Hydraulic Slave Cylinders & Wheel Cylinders Product Guide

中英文对照资料外文翻译文献Automobile Brake SystemThe braking system is the most important system in cars. If the brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes.Two complete independent braking systems are used on the car. They are the service brake and the parking brake.The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set.The brake system is composed of the following basic components: the “master cylinder” which is located under the hood, and is directly connected tothe brake pedal, converts driver foot’s mechanical pressure into hydraulic pressure. Steel “brake lines” and flexible “brake hoses” connect the master cylin der to the “slave cylinders” located at each wheel. Brake fluid, specially designed to work in extreme conditions, fills the system. “Shoes” and “pads” are pushed by the slave cylinders to contact the “drums” and “rotors” thus causing drag, which (hopefully) slows the car.The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure).Basically, all car brakes are friction brakes. When the driver applies the brake, the control device forces brake shoes, or pads, against the rotating brake drum or disks at wheel. Friction between the shoes or pads and the drums or disks then slows or stops the wheel so that the car is braked.In most modern brake systems (see Figure 15.1), there is a fluid-filled cylinder, called master cylinder, which contains two separate sections, there is a piston in each section and both pistons are connected to a brake pedal in the driver’s com partment. When the brake is pushed down, brake fluid is sent from the master cylinder to the wheels.At the wheels, the fluid pushes shoes, or pads, against revolving drums or disks. The friction between the stationary shoes, or pads, and the revolving drums or disks slows and stops them. This slows or stops the revolving wheels, which, in turn, slow or stop the car.The brake fluid reservoir is on top of the master cylinder. Most cars today have a transparent r reservoir so that you can see the level without opening the cover. The brake fluid level will drop slightly as the brake pads wear. This is a normal condition and no cause for concern. If the level drops noticeably over ashort period of time or goes down to about two thirds full, have your brakes checked as soon as possible. Keep the reservoir covered except for the amount of time you need to fill it and never leave a cam of brake fluid uncovered. Brake fluid must maintain a very high boiling point. Exposure to air will cause the fluid to absorb moisture which will lower that boiling point.The brake fluid travels from the master cylinder to the wheels through a series of steel tubes and reinforced rubber hoses. Rubber hoses are only used in places that require flexibility, such as at the front wheels, which move up and down as well as steer. The rest of the system uses non-corrosive seamless steel tubing with special fittings at all attachment points. If a steel line requires a repair, the best procedure is to replace the compete line. If this is not practical, a line can be repaired using special splice fittings that are made for brake system repair. Y ou must never use copper tubing to repair a brake system. They are dangerous and illegal.Drum brakes, it consists of the brake drum, an expander, pull back springs, a stationary back plate, two shoes with friction linings, and anchor pins. The stationary back plate is secured to the flange of the axle housing or to the steering knuckle. The brake drum is mounted on the wheel hub. There is aclearance between the inner surface of the drum and the shoe lining. To apply brakes, the driver pushes pedal, the expander expands the shoes and presses them to the drum. Friction between the brake drum and the friction linings brakes the wheels and the vehicle stops. To release brakes, the driver release the pedal, the pull back spring retracts the shoes thus permitting free rotation of the wheels.Disk brakes, it has a metal disk instead of a drum. A flat shoe, or disk-brake pad, is located on each side of the disk. The shoes squeeze the rotatin g disk to stop the car. Fluid from the master cylinder forces the pistons to move in, toward the disk. This action pushes the friction pads tightly against the disk. The friction between the shoes and disk slows and stops it. This provides the braking action. Pistons are made of either plastic or metal. There are three general types of disk brakes. They are the floating-caliper type, the fixed-caliper type, and the sliding-caliper type. Floating-caliper and sliding-caliper disk brakes use a single piston. Fixed-caliper disk brakes have either two or four pistons.The brake system assemblies are actuated by mechanical, hydraulic or pneumatic devices. The mechanical leverage is used in the parking brakes fitted in all automobile. When the brake pedal is depressed, the rod pushes the piston of brake master cylinder which presses the fluid. The fluid flows through the pipelines to the power brake unit and then to the wheel cylinder. The fluid pressure expands the cylinder pistons thus pressing the shoes to the drum or disk. If the pedal is released, the piston returns to the initialposition, the pull backsprings retract the shoes, the fluid is forced back to the master cylinder and braking ceases.The primary purpose of the parking brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by the driver when a separate parking braking hand lever is set. The hand brake is normally used when the car has already stopped. A lever is pulled and the rear brakes are approached and locked in the “on” position. The car may now be left without fear of its rolling away. When the driver wants to move the car again, he must press a button before the lever can be released. The hand brake must also be able to stop the car in the event of the foot brake failing. For this reason, it is separate from the foot brake uses cable or rods instead of the hydraulic system.Anti-lock Brake SystemAnti-lock brake systems make braking safer and more convenient, Anti-lock brake systems modulate brake system hydraulic pressure to prevent the brakes from locking and the tires from skidding on slippery pavement or during a panic stop.Anti-lock brake systems have been used on aircraft for years, and some domestic car were offered with an early form of anti-lock braking in late 1990’s. Recently, several automakers have introduced more sophisticated anti-lock system. Investigations in Europe, where anti-lock brakin g systems have been available for a decade, have led one manufacture to state that the number of traffic accidents could be reduced by seven and a half percent if all cars hadanti-lock brakes. So some sources predict that all cars will offer anti-lock brakes to improve the safety of the car.Anti-lock systems modulate brake application force several times per second to hold the tires at a controlled amount of slip; all systems accomplish this in basically the same way. One or more speed sensors generate alternating current signal whose frequency increases with the wheel rotational speed. An electronic control unit continuously monitors these signals and if the frequency of a signal drops too rapidly indicating that a wheel is about to lock, the control unit instructs a modulating device to reduce hydraulic pressure to the brake at the affected wheel. When sensor signals indicate the wheel is again rotating normally, the control unit allows increased hydraulic pressure to the brake. This release-apply cycle occurs several time per second to “pump” the brakes like a driver might but at a much faster rate.In addition to their basic operation, anti-lock systems have two other things in common. First, they do not operate until the brakes are applied with enough force to lock or nearly lock a wheel. At all other times, the system stands ready to function but does not interfere with normal braking. Second, if the anti-lock system fail in any way, the brakes continue to operate without anti-lock capability. A warning light on the instrument panel alerts the driver when a problem exists in the anti-lock system.The current Bosch component Anti-lock Braking System (ABSⅡ), is a second generation design wildly used by European automakers such as BWM,Mercedes-Benz and Porsche. ABSⅡsystem consists of : four wheel speed sensor, electronic control unit and modulator assembly.A speed sensor is fitted at each wheel sends signals about wheel rotation to control unit. Each speed sensor consists of a sensor unit and a gear wheel. The front sensor mounts to the steering knuckle and its gear wheel is pressed onto the stub axle that rotates with the wheel. The rear sensor mounts the rear suspension member and its gear wheel is pressed onto the axle. The sensor itself is a winding with a magnetic core. The core creates a magnetic field around the winding, and as the teeth of the gear wheel move through this field, an alternating current is induced in the winding. The control unit monitors the rate o change in this frequency to determine impending brake lockup.The cont rol unit’s function can be divided into three parts: signal processing, logic and safety circuitry. The signal processing section is the converter that receives the alternating current signals form the speed sensors and converts them into digital form for the logic section. The logic section then analyzes the digitized signals to calculate any brake pressure changes needed. If impending lockup is sensed, the logic section sends commands to the modulator assembly. Modulator assemblyThe hydraulic modulator assembly regulates pressure to the wheel brakes when it receives commands from the control utuit. The modulator assembly can maintain or reduce pressure over the level it receives from the master cylinder, it also can never apply the brakes by itself. The modulator assembly consists ofthree high-speed electric solenoid valves, two fluid reservoirs and a turn delivery pump equipped with inlet and outlet check valves. The modulator electrical connector and controlling relays are concealed under a plastic cover of the assembly.Each front wheel is served by electric solenoid valve modulated independently by the control unit. The rear brakes are served by a single solenoid valve and modulated together using the select-low principle. During anti-braking system operation, the control unit cycles the solenoid valves to either hold or release pressure the brake lines. When pressure is released from the brake lines during anti-braking operation, it is routed to a fluid reservoir. There is one reservoir for the front brake circuit. The reservoirs are low-pressure accumulators that store fluid under slight spring pressure until the return delivery pump can return the fluid through the brake lines to the master cylinder.汽车制动系统制动系统是汽车中最重要的系统。

外文原文Automobile chassisChassis include the clutch , the transmission, the drive shaft, the final drive assembly, the front suspension, the rear suspension, the steering system ,the brake system, the wheels and tires.1.ClutchThe engine produces the power to drive the vehicle . The drive line or drive train transfer the power of the engine to the wheels . The drive train consists of the parts from the back of the flywheel to the wheels . These parts include the clutch , the transmission ,the drive shaft ,and the final drive assembly .The clutch which includes the flywheel ,clutch disc , pressure plate , springs , pressure plate cover and the linkage necessary to operate the clutch is a rotating mechanism between the engine and the transmission . It operates through friction which comes from contact between the parts . That is the reason why the clutch is called a friction mechanism . After engagement, the clutch must continue to transmit all engine torque to transmission depending on the friction without slippage . The clutch is also used to disengage the engine from the drive train whenever the gears in the transmission are being shifted from gear ratio to another .To start the engine or shift the gears , the driver has to depress the clutch pedal with the purpose of disengagement the transmission from the engine . At that time , the driven members connected to the transmission input shaft are either stationary or rotating at a speed that is slower of faster than the driving members connected to engine crankshaft . There is no spring pressure on the clutch assembly parts . So there is no friction between the driving members and driven members . As the driver lets loose the clutch pedal , spring pressure increase on the clutch parts . Friction between the parts also increases . The pressure exerted by the springs on the driven members is controlled by the driver through the clutch pedal and linkage . The positive engagement of the driving and driven members is made possible the friction between the surfaces of the members . When full spring pressure is applied , the speed of the driving and driven members should be the same . At the moment , the clutch must act as a coupling device and transmit all engine power to the transmission , without slipping .However , the transmission should be engaged to the engine gradually in order to operate the car smoothly and minimize torsional shock on the drive train because an engine at idle just develop little power . Otherwise , the driving members are connected with the driven members too quickly and the engine would be stalled .The flywheel is a major part of the clutch . The flywheel mounts to the engine’s crankshaft and transmits engine torque to the clutch assembly . The flywheel , when coupled with the clutch disc and pressure plate makes and breaks the flow of power the engine to the transmission .The flywheel provides a mounting location for the clutch assembly as well . When the clutch is applied , the flywheel transfers engine torque to the clutch disc . Because of its weight , the flywheel helps to smooth engine operation . The flywheel also has a large ring gear at its outer edge , which engages with a pinion gear on the starter motor during engine cranking .The clutch disc fits between the flywheel and the pressure plate . The clutch disc has a splined hub that fits over splines on the transmission input shaft . A splined hub has grooves that match splines on the shaft . These splines fit in the grooves . Thus , the two parts held together . However , back – and – forth movement of the disc on the shaft is possible . Attached to the input shaft , the disc turns at the speed of the shaft .The clutch pressure plate is generally made of cast iron . It is round and about the same diameter as the clutch disc . One side of the pressure plate is machined smooth . This side will press the clutch disc facing are against the flywheel . The outer side has shapes to facilitate attachment of spring and release mechanism . The two primary types of pressure plate assemblies are coil spring assembly and diaphragm spring .Diaphragm spring pressure plate assemblies are widely used in most modern cars . The diaphragm spring is a single thin sheet of metal which yields when pressure is applied to it . When pressure is removed the metal spring back to its original shape . The center portion of the diaphragm spring is slit into numerous fingers that act as release levers . When the clutch assembly rotates with the engine these weights are flung outwards by centrifugal plate and cause the levers to press against the pressure plate . During disengagement of the clutch the fingers are moved forward by the release bearing . The spring pivots over the fulcrum ring and its outer rim moves away from the flywheel . The retracting spring pulls the pressure plate away from the clutch plate thus disengaging the clutch .When engaged the release bearing and the fingers of the diaphragm spring move towards the transmission . As the diaphragm pivots over the pivot ring its outer rim forces the pressure plate against the clutch disc so that the clutch plate is engaged to flywheel .The advantages of a diaphragm type pressure plate assembly are its compactness , lower weight , fewer moving parts , less effort to engage , reduces rotational imbalance by providing a balanced force around the pressure plate and less chances of clutch slippage .2. Automatic transmissionThe modern automatic transmission is by far , the most complicated mechanical component in today’s aut omobile . It is a type of transmission that sifts itself . A fluid coupling or torque converter is used instead of a manually operated clutch to connect the transmission to the engine .There are two basic types of automatic transmission based on whether the vehicle is rear wheel drive or front wheel drive . On a rear wheel drive car , the transmission is usually mounted to the back of the engine and is located under the hump in the center of the floorboard alongside the gas pedal position . A drive shaft connects the transmission to the final drive which is located in the rear axle and is used to send power to the rear wheels . Power flow on this system is simple and straight forward going from the engine , through the torque converter , then trough the transmission and drive shaft until it reaches the final drive where it is split and sent to the two rear transmission .On a front wheel drive car , the transmission is usually combined with the final drive to form what is called a transaxle . The engine on a front wheel drive car is usually mounted sideways in the car with the transaxle tucked under it on the side of the engine facing the rear of the car . Front axles are connected directly to the transaxle and provide power to front wheels . In this example , power floes from the engine , through the torque converter to a larger chain that sends the power through a 180 degree turn to the transmission that is along side the engine . From there , the power is routed through the transmission to the final drive where it is split and sent to the two front wheels through the drive axles .There are a number of other arrangements including front drive vehicles where the engine is mounted front to back instead of sideways and there are other systemsthat drive all four wheels but the two systems described here are by far the most popular . A much less popular rear and is connected by a drive shaft to the torque converter which is still mounted on the engine . This system is found on the new Corvette and is used in order to balance the weight evenly between the front and rear wheels for improved performance and handling . Another rear drive system mounts everything , the engine , transmission and final drive in the rear . This rear engine arrangement is popular on the Porsche.The modern automatic transmission consists of many components and systems that designed to work together in a symphony of planetary gear sets , the hydraulic system, seals and gaskets , the torque converter , the governor and the modulator or throttle cable and computer controls that has evolved over the years into what many mechanical inclined individuals consider to be an art from .3.The Differential SystemWhen a vehicle is cornered the inner wheel moves through a shorter distance than the outer wheel . This means that the inner wheel must slow down and the outer wheel must speed up . During this period it is desirable that each driving maintains its driving action . The differential performs these two tasks . The principle of the bevel type differential can be seen if the unit is considered as two discs and a lever .When the vehicle is traveling straight , the lever will divide the diving force equally and both discs will move the same amount .When the vehicle corners , the driving will still be divided equally but the inner disc will now move through a smaller distance ;this will cause the lever to pivot about its center which will prize forward the outer disc to give it a greater movement . This action shows that the torque applied to each driving wheel is always equal – hence the differential is sometimes called a torque equalizer .4.Brake SystemThe breaking system is the most important system in cars . If the brakes fail , the result can be disastrous . Brakes are actually energy conversion devices , which convert the kinetic energy ( momentum ) of the vehicle into thermal ( heat ) . When stepping on the brakes , the driver commands a stopping force ten times as powerful as the force that puts the car in motion . The braking system can exert thousands of pounds of pressure on each of the four brakes .The brake system is composed of the following basic components : the “master cylinder” which is located under the hood , and is directly connected to the brak e pedal , converts driver foot’s mechanical pressure into hydraulic pressure . Steel “brake lines” and flexible “brake hoses” connect the master cylinder to the “slave cylinders” located at each wheel . Brake fluid , specially designed to work in extreme c ondition , fills the system . “Shoes” and “Pads” are pushed by the salve cylinders to contact the “drum” and “rotors” thus causing drag , which ( hopefully ) slows the car .The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder .Stepping on the brake pedal , a plunger is actually been pushing against in the master cylinder which forces hydraulic oil ( brake fluid ) through a series of tubes and hoses to the braking unit at each wheel . Since hydraulic fluid ( or any fluid for that matter ) cannot be compressed , pushing fluid through a pipe is just like pushing a steel bar through pipe . Unlike a steel bar , however , fluid can be directed through many twists and turns on its way to its destination , arriving with the exact same motion and pressure that it started with . It is very important that the fluid is pure liquid and that there are no air bubbles in it . Air can compress , which causes a sponginess to the pedal and severely reduced braking efficiency . If air is suspected , then the system must be bled to remove the air . There are “bleeder screws” at each wheel and caliper for this purpose .On a disk brakes , the fluid from the master cylinder is forced into a caliper where it pressure against a piston . The piton , in-turn , squeezes two brake pads against the disk ( rotor ) which is attached to the wheel , forcing it to slow down or stop . This process is similar to the wheel ,causing the wheel to stop . In either case , the friction surface of the pads on a disk brake system , on the shoes on a drum brake convert the forward motion of the vehicle into heat . Heat is what causes the friction surfaces ( lining ) of the pads and shoes to eventually wear out and require replacement .Brake fluid is a special oil that has specifics properties . It is designed to withstand cold temperatures without thickening as well as very high temperatures without boiling . ( If the brake fluid should boil , it will cause you to have a spongy pedal and the car will be hard to stop ) .The brake fluid reservoir is on top of the master cylinder . Most cars today have a transparent reservoir so that you can see the level without opening the cover . The brake fluid lever will drop slightly as the brake pads wear . This is a normal condition and no cause for concern . If the lever drops noticeably over a short period of time or goes down to about two thirds full , have your brakes checked as soon as possible . Keep the reservoir covered expect for the amount of time you need to fill it and never leave a can of brake fluid uncovered . Brake fluid must maintain a very high boiling point . Exposure to air will cause the fluid to absorb moisture which will lower that boiling point .The brake fluid travels from the master cylinder to the wheels through a series of steel tubes and reinforced rubber hoses . Rubber hoses are only used in places that require flexibility , such as at the front wheels , which move up and down as well as steer . The rest of the system uses non-corrosive seamless steel tubing with special fittings at attachment points . If a steel line requires a repair , the best procedure is to replace the complete line . If this is nit practical , a line can be repaired using special splice fittings that are made for brake system repair . You must never use brass “compression” fittings or copper tubing repair a brake system . They are dangerous and illegal .5.Steering SystemSteering system's basic components: to control, steering gear and steering transmission mechanism composed of three parts.The steering converts the steering –wheel rotary motion into a turn motion of the steered wheels of the vehicle .The basic steering system in most cars is the same . The steering gear of steering box is the heart of the steering system .This is usually next to the engine . A shaft extends from the back of the steering gear . This shaft is connected to the steering column or steering shaft . The steering wheel is at the top of the steering column . Another shaft comes from the bottom of the steering gear . This shaft connects to the arms , rods , and links . This parts assembly , called the steering linkage , connects the steering gear to the parts at the wheels . The wheels and tires mount to the steering knuckles , As shown in fig , the knuckles are pivoted at the top and bottom . Thus , the wheels and rites can turn from side top side .Types of Steering SystemA steering box must have the following qualities :1) no play in the straight-ahead position2)low friction , resulting in high efficiency3)high rigidity ,4 )read justabilityFor these reasons , these are several different types of steering gears . However , there are only two types of steering systems : manual steering systems and power steering systems . In the manual type , the driver dose all the work of turning the steering wheel , steering gear , wheels and tires . In the power , hydraulic fluid assists the operation so that driver effort is reduced .On today’s cars , two types of steering systems commonly are used to provide steering control :1) recirculating ball2) rack and pinionEither of these two types of steering mechanisms may be a fully mechanical systems or a power –assisted system .6.Front SuspensionThe front suspension is more complicated than the rear suspension . This is because the front wheels must move in several different directions . The wheels must move up and down with the suspension and turn left to right with the steering . Since the car goes in the direction in which the front wheels point , the alignment of the front wheels is important . The wheels must point in just the right direction for the car to move straight down the road and turn properly .Modern cars uses an independent front suspension . In this system , each wheel mounts separately to the frame and has its own individual spring and shock absorber . Thus , the wheels act independently of one another . When one wheel hits a bump or hole in the road , the other wheel dose no9t deflect .Front Wheel AlignmentAs a car moves down the high-way , the suspension moves the front wheels up and down . At the same time , the steering mechanism moves the front wheels , sometimes to make turns and sometimes to make the travel straight . The angular relationship between the wheels and suspension parts during this motion is thefront-end geometry . Since the geometry can change the alignment of front wheels is adjustable . You can change the adjustment to compensate for spring sag .The alignment of the front wheels affects the operation of a car . Poor alignment ca make a car pull to one side and stop the front wheels from returning to the straight-ahead position after a turn . The three normally adjustable angles are caster , camber , and toe .1 )CasterCaster is the forward or backward of spindle or steering the knuckle at the top when viewed from the side . Forward tilt is negative caster and backward tilt positive caster . Caster is measured in the number of degrees that it is forward or backward from true vertical and is adjustable on many vehicle .2.) Kingpin AngleThe kingpin angle is the inclination of the steering axis relative to the longitudinal plane , measured in the transverse plane of the vehicle . Kingpin angle is 2°-16°and determines the steering aligning torque in conjunction with steering offset and wheel caster . It is measured only with the vehicle loaded .3.) CamberCamber is the inward or outward tilt of the wheel at the top . Inward tilt is negative camber and outward tilt is positive camber . The tilt of the wheel is measured inn degrees and is adjustable on many vehicles .4) Toe-inToe-in specifies the degree to which non-parallel front wheels are closer together at the front than at th e rear ; measured at the edges of the rims at the wheel center height . front non-driven wheels , toe-in is approximately 2-3 mm , and between 3mm and-2mm for driven wheels . Toe-in reduces the tendency of the wheels to shimmy .7.Rear SuspensionThe purpose of the rear suspension is to support the weight of the rear of the vehicle . As with the front suspension , this system contributes to the stability and ride of the vehicle . Rear suspension may be of the solid axle or independent design . Many cars have solid axle rear suspension . Either design may have different kinds of springs , including torsion bars . However , the coil spring and leaf spring types are most popular .8.Wheels and TiresTo maintain grip when a vehicle is traveling at speed over a bumpy surface , a wheel must be light in weight . Also it must be strong , cheap to produce , easy to clan and simple to remove .WheelsThe structure of the wheel is shown in Fig . The rim is made in one piece , with the wheel center welded or riveted to it . Most modern vehicles use the drop center type . This drop center provides a well for tire bead to drop into for tire removal . A slight hump at the head ledge holds the tire in place should it go flat while driving .TiresTires are important to your safety and comfort . They transmit the driving and braking power to the road . The car’s directional con trol , road-ability and riding comfort are greatly dependent on the tires . Tires should be selected and maintained with great care .There are two basic types of tires –those with inner tubes and those without ( called “tubeless” tires ) . Most mode rn automobile tires are of the tubeless type . Truck and bus tire are usually of the tube type .Tires are made of several layers of nylon , rayon , or polyester fabric bonded together with belts of rayon , fiberglass , or steel cord . The rubber used in tires is a blend of natural and synthetic rubber .中文译文汽车底盘底盘包括：离合器、变速器、传动轴、主减速器、前悬架、后悬架、制动系、转向系、车轮和轮胎。

In January2005 the HV2 Series rod bushing and bolted retainer design wererevised to allow more universal interchange with Miller H and HVSeries cylinders. This change resulted in two different style rod bush -ing and rod seal kits; one for the July 2002 version and another for theJanuary 2005 version. Additionally, the July 2002 HV2 had a standard nodular iron bushing without a cataloged material option: the January 2005 HV2 has a standard bronze bushing and an optional nodular iron bushing. The January 2005 HV2 model code was revised with an additional seal field that will identify the new design.Cylinders ordered after January 5, 2005 can be identified by a model code that includes a seal material specification. See the example below (or refer to Catalog M1140-2 or later) and compare to the cylinder label model number. Cylinders ordered prior to January 5, 2005 do not have a seal material specification in the model code HV272B2N-04.00-8.000-0175-S11T -0 - where T =Class 1 seals, V =C lass 5 seals RodDia.Seal TypeClass 1 Service Polyurethane & Buna-NClass 5 Service FluorocarbonBronze Bushing Kits † Nodular Iron Bushing Kits † Rod Seal Kits † Bronze Bushing Kits † Nodular IronBushing Kits †Rod SealKits †5/8HV2-KR110-63HV2-KR120-63HV2-KR310-63HV2-KR210-63HV2-KR220-63HV2-KR410-631HV2-KR110-100HV2-KR120-100HV2-KR310-100HV2-KR210-100HV2-KR220-100HV2-KR410-1001 3/8HV2-KR110-138HV2-KR120-138HV2-KR310-138HV2-KR210-138HV2-KR220-138HV2-KR410-1381 3/4HV2-KR110-175HV2-KR120-175HV2-KR310-175HV2-KR210-175HV2-KR220-175HV2-KR410-1752HV2-KR110-200HV2-KR120-200HV2-KR310-200HV2-KR210-200HV2-KR220-200HV2-KR410-2002 1/2HV2-KR110-250HV2-KR120-250HV2-KR310-250HV2-KR210-250HV2-KR220-250HV2-KR410-2503HV2-KR110-300HV2-KR120-300HV2-KR310-300HV2-KR210-300HV2-KR220-300HV2-KR410-3003 1/2HV2-KR110-350HV2-KR120-350HV2-KR310-350HV2-KR210-350HV2-KR220-350HV2-KR410-3504HV2-KR110-400HV2-KR120-400HV2-KR310-400HV2-KR210-400HV2-KR220-400HV2-KR410-4005HV2-KR110-500HV2-KR120-500HV2-KR310-500HV2-KR210-500HV2-KR220-500HV2-KR410-5005 1/2HV2-KR110-550HV2-KR120-550HV2-KR310-550HV2-KR210-550HV2-KR220-550HV2-KR410-550† Contents and Part Numbers of Seal Kits For Rod Bushings (Seekey to part numbers on page 1)Rod Bushing Kits – Contain items 14, 40, 41, 45, 115 (2002 HV2 only), (43 class 2 & 5 only except 5/8" & 1" rod in 2004 HV2.)Rod Seal Kits – Contain items 40, 41, 45, 115 (2002 HV2 only), (43 class 2 & 5 only except 5/8" & 1" rod in 2004 HV2.)Cushion Screw Assembly – Screw type: 69, 70.

Install one piston seal in the groove nearest the rod. The two ‘lips’ of this Lipseal should face toward the rod end of the piston. Install the back-up washer in the same groove opposite the 'lips' of the seal. Lubricate the cylinder body ID and insert the piston – cap end first – into the cylinder body as shown.Next, turn the cylinder body on its side and push the piston through the tube just far enough to expose the groove for the second seal. Now, install the second Lipseal and back-up washer in the exposed groove with the two ‘lips’ facing away from the rod. Then pull the piston into the cylinder tubeHi-Load PistonKits for Hi-Load pistons contain two sets of seals for 1½" - 6"bore cylinders and one set of seals for 7" - 8" bore cylinders.Each seal set includes one filled PTFE sealing ring (119) andan elastomeric energizing ring (120). The kit also contains twowear rings (121). Install the inner energizing ring(s) in the sealgroove(s).Install the wear rings in the two grooves on each end ofthe piston. Stretch the PTFE seal ring(s) by hand until it fitsover the wear ring. Push the outer ring(s) over the wearring and into the seal groove(s). With the outer ring(s) inthe groove(s), compress them with a ring compressor.Alternatively, the PTFE rings can be compressed using alarge hose clamp over thin shim stock. In all cases, take carenot to damage the sealing ring(s). Keep the sealing ring(s)compressed for some time before inserting the piston intothe tube. A starting sleeve having an ID the same size as thecylinder bore, and tapered at one end, will aid the installationprocess.Cast Iron Piston RingsKits for cast iron piston rings contain four rings (48). Ironpiston rings seldom need replacement. If the rings show nosigns of damage or abnormal wear, they may be reused.To install piston rings, collapse the rings one at a time whileinserting the piston into the cylinder body, using a light oil toaid this process.Cylinder Modifications or RepairsCylinders as shipped from the factory are not to be disassem-bled and or modified. If cylinders require modifications, thesemodifications must be done at company locations or by TheCompany's certified facilities. The Cylinder Division Engineer-ing Department must be notified in the event of a mechanicalfracture or permanent deformation of any cylinder component(excluding seals). This includes a broken piston rod, tie rod,mounting accessory or any other cylinder component. Thenotification should include all operation and application details.This information will be used to provide an engineered repairthat will prevent recurrence of the failure.It is allowed to disassemble cylinders for the purpose of replac-ing seals or seal assemblies. However, this work must be doneby strictly following all the instructions provided in this bulletin.Although Miller Hydraulic Cylinders are designed to make on-site maintenance or repairs as easy as possible, some opera-tions can only be carried out in our factory. It is standard policyto fit a cylinder returned to the factory for repair with thosereplacement parts which are necessary to return it to ‘as goodas new’ condition. Should the condition of the returned cylinderbe such that repair would be uneconomical, you will be notified.The piston is sealed and securely locked to the piston rod withanaerobic adhesive. This threaded connection is ONLY to be: Some cylinders contain heavily loadedsevere bodily injury or death. Always disassemble a cylindercontaining a spring by following the instructions in Bulletin0805-G-TSD-1.After the cylinder has been disassembled, carefully remove theseals that will be replaced to avoid damaging groove surfaces.Carefully clean all parts.Seals will be easier to install if they are lubricated. Alwayslubricate seals and other components of a hydraulic cylinderwith the operating fluid. Cylinders fitted with Class 3 seals(EPR) cannot be lubricated or operated with petroleum basedproducts.Servicing Piston SealsThe cylinder bore and piston must be closely examined forsigns of scoring. If either the cylinder tube or piston is damagedthey must be replaced.When a cylinder is overhauled, a new set of piston seals isrequired. It is also recommended that the cylinder be reassem-bled with new cylinder tube O-rings. All piston seal kits containpiston seals as well as two cylinder tube O-rings (47) and for7 and 8 inch bore hydraulic cylinders, their mating back-upwashers (26).1 1/2 - 6" Bore7" & 8" BoreCylinder AssemblyThe cylinder should be re-assembled as follows:1) The back-up washers, where fitted, and then the tubeO-rings should be lightly lubricated and pressed into the grooves in the head and cap, without twisting. The cylinder tube, with the piston and rod already fitted, can then be assembled to the cap by ‘rocking’ it down over the O-ring until the cylinder tube is in contact with the cap. The head is then fitted over the piston rod and assembled to the cylinder tube. Rock gently until the tube and head are in metal-to-metal contact.2) Lightly lubricate the bushing seals.3) Slide the bushing over the piston rod end, taking care not to damage the seal lips. Slide the small circular or full square retainer over the bushing. Orient holes in full square retainers over the tie rod holes in the head or line up holes in smaller retainers with threaded mounting holes. Assemble bolts that secure bolt-on retainers finger tight. 4) Ensuring that the head and cap are kept in alignment, refit the cylinder tie rods.Note: Some cylinder configurations have tie rods threaded into a component other than tie rod nuts(e.g. head, cap, flange plate, etc). Before torquing thetie rods, use paint on the tie rods as an indicator that adequate thread engagement is achieved. Ensure thatno unpainted thread is exposed at the connection to the mating component.For both style retainers, torque tie rod nuts to values listed on page 6. Torque tie rods gradually starting at one corner and work in a diagonal pattern to ensure evenness of tightening. DO NOT TORQUE ONE TIE ROD COMPLETELY AND THEN THE OTHERS. Then, on cylinders with bolt-on retainers, torque bolts to the values listed on page 6.Trunnion MountsTrunnion mount with trunnion in groove on cylinder body – Torque cap end tie rods to value listed in table, then torque head tie rods to the same value.Trunnion mounts with trunnion located against a single shoulder on the cylinder body – Torque tie rods on the larger diameter side of the shoulder to approx. 10% of torque table value. Then torque the tie rods on the opposite end to the full table value.Trunnion mounts located on a cylinder body without a shoulder – Assemble short set of tie rods first, using paint marks on the cylinder body as a location guide. Ensure the trunnion pins are square to the body. Install the longer tie rods and torque to values in the table.Servicing Cushion Needle and Check ValvesLeakage from cushion adjusters or check valve screws indicates that the screw or cartridge-type assembly must be replaced. The replacement assembly includes a new O-ring. RemovalThe screw/cartridge assembly should be unscrewed and its mounting hole cleaned, paying close attention to the surface on which the O-ring sits.Installation – Cushion Needle ValvesWhere a cartridge-type adjuster is fitted, lightly lubricate the screw threads and torque to the figures shown in the tableon page 6. With both types, the hex-headed screw may be adjusted to provide the required cushioning performance. Installation – Check ValveEnsure that the ball is correctly positioned. Screw-type adjusters should be screwed fully home, and then backed off by a full turn. Servicing Cylinder Bushing SealsFluid leakage from the piston rod at the bushing normally indicates worn rod seals. The cylinder should, if possible, be removed for overhaul, or the piston rod disconnected. Removal1) Inspect the piston rod to make sure it is free from burrs or damage which would prevent the bushing sliding offthe rod.The Miller bushing is a cartridge design consisting of a bronze or iron bushing (14), primary rod seal (41), back-up washer (43) for all hydraulic cylinder seal classes, and a double lip wiperseal (40). The HV2 bushing is usually held in place with a bolt-on retainer. However, some HV2 Series mounting styles with oversize piston rod diameters will utilize a retainer plate held in place by tie rods.2) Where the bushing is secured by a circular retainer, undo the socket head cap screws and slide the bushing and retainer off the piston rod.3) Remove the seals using a sharp pointed instrument, taking care not to damage the bushing. Clean and inspect the bushing bore and seal grooves. If any wear is present replace with a Rod Bushing Kit containing seals of the correct type for the conditions.Inspect the surface of the piston rod for damage which could cause early seal failure. When fitting the bushing over the rod thread, a slight rotary motion will help prevent damage to the seals. In addition, shim stock or other thin, tough material can be wrapped around the threads to protect the seal lips.1) Ensure that the kit contains seals of the correct type. Lubricate the bushing and seals, and fit the wiper (40) into the groove closest to the outside face of the bushing.2) If a Class 1 material rod seal is being fitted to a standard bushing, no back-up washer is necessary. A back-up washer (43) is included in seal kits for all other service classes. Install this in the rod seal groove, against the wall closest to the wiper. Install the lipseal (41) in the groove, with the lips facing the pressure (cylinder) side of the bushing.3) Slide the bushing cartridge over the piston rod end thread and into the cylinder head. Place the retainer plate over the bushing, install the mounting bolts and torque to the values listed on page 6. Note that some mounting styles with oversize piston rod diameters will utilize a retainer plate held in place by tie rods.4) Each kit contains an O-ring (45) which seals the bushing to the cylinder head. This O-ring is a static seal, and the original must be left in place unless it is faulty.For cylinders that utilize a retainer plate held in place by tie rods, torque the rod nuts to values listed on page 6. Torque tie rods gradually starting at one corner and work in a diagonal pattern to ensure evenness of tightening.DO NOT TORQUE ONE TIE ROD COMPLETELY AND THEN THE OTHERS.Rod seals are pressure activated and do not need adjustment.Miller Fluid Power 500 South Wolf RoadDes Plaines, IL 60016 USA Tel.: (847) 298-2400 Fax: (800) 892-1008Miller Fluid Power 160 Chisholm Drive Milton, Ontario Canada L9T 3G9Tel.: (905) 693-3000Fax: (905) 876-1958© Copyright 2005, 2009, 2015 Miller Fluid Power.

Whether it’s compact winches in closed cir-cuit, winch drives in open circuit or secondary control drives for maximum dynamics: Rexroth is the right partner when it comes to winch drives in all performancecategories.Our specialty – compact winches in closed cycle operation Rexroth’s compact winches are characterized by their flexible and straightforward installation. This dispenses with the need for com-plicated pipework.MOBILEX GFT-WHydrostaticMOBILEX gearboxMOBILEX GFT-W- gearboxes are ideal drive components for crane winches with low-noise operation. As a result of their extremely installa-tion-friendly and compact design they can be fitted directly into the cable reels, thus saving space.In addition to an extensive range of standard products, Rexroth offers solutions specially devel-oped for marine applications. This means optimum adaptation of your requirements to the winch drive.44WMM16TH7A10VSO A6VM WCB Winch control block Whether it’s a towline winch with high un-laden rope speed, a mooring winch with automatic rope tight-ening or an anchor winch with an initial break-away torque increased by 50 %: the WCB, with its sea-water-resistant deck construction and mo-dular design, caters for every eventuality, both on its own or when used in combination. The WCB also fea-tures a choice between manual, hydraulic or electric controls.Hydraulic motors The robust A6VM hydraulic motor with its broad adjustment range and high power-density permits high unladen rope speeds.Swashplate pumpThe A10VSO open circuit swashplate pump has proved it-self as a standard for winch units. And this is not the only reason why these pumps have been used for more than 20 years in maritime applications all over the world.Remote control devicesThe TH7 remote con-trol device enables sen sitive control of the winch by using different control curves.Winch valvesThe WMM 16 SO840 proportional valve, featuring an electric or hydraulic remote control facility, has been specially de-veloped to meet the demand for smooth and jerk-free start-up of winch drums. This is in part achieved by means of a particular-ly low-friction valvepiston.5Rudder Systems –Right on Course Maximum maneuverability,optimum efficiency, safety and economy in operation – Rexroth supplies the technology to ensurethat you steer the right course.In order to ensure smooth opera-tion of the rudder system, Rexroth supplies robust and reliable com-ponents reflecting state-of-the-art technology.Proportional valves with integra-ted switch position monitoringSo as to enabling monitoring ofthe function and position of therudder at any time, Rexroth hasopted for the WRZ proportionalvalve with integrated switch po-sition monitoring. This valve hasbeen specially developed for these applications.Axial piston pumpsThe extremely robust and reliable A4CSG axial piston pump, with integral feed pump and valve tech-nology, has proved itself in relation to these applications.CylindersRexroth supplies the right cylinder for all the steering power required. The pressurized parts of the cy-linders are supplied with certified material in accordance with the re-levant classification specifications.A4CSG CylinderWRZ Redundant rudder system for a 7,500 TEUcontainer freighter6Powerful, safe and efficient operation – Rexroth brings motion into play .Turning, lifting, pushing: efficient power application hand-in-hand with maximum reliability in ope-ration– behind all this is Rexroth technology.Power UnitsRexroth supplies matching “power packs” to meet the requirements of every drive in marine techno-logy – manufactured to a uniform standard, as with all our compo-nents and systems. This guarantees economic efficiency, long service life and reliability.Swivel Drives The hydrostatic MOBILEX-GFB swivel drives are used for therotary movements in ships’ cranes and with side rolling hatch cover drives. They have proved them-selves in tough applications and under adverse conditions of use.M4-12MOBILEX-GFBPower Unit Cranes, Davits, Hatch Covers – Motion with Rexroth SystemsHigh Pressure Control BlocksThe crane is controlled by the high pressure control blocks M4-12, 15 and 22 in disc design. These blocks operate with load sensing to save energy. For different loads and where a number of actuators are operated at the same time, load pressure compensation ensures that the same speed can be main-tained. The blocks can be operated mechanically, hydraulically, elec-tro-hydraulically or with on-board electronics. In addition, the M7-22 monoblock with its load-indepen-dent flow distribution ensures that all the actuators can continue to run at a proportionally reduced speed even where the volume flow is insufficient.7Valves and Cylinders with protec-tion against seawater Rexroth offers you a unique range of components featuring protec-tion against seawater. Seawater-resistant steel or even brass is used at critical points in construc-tion. It goes without saying that robust electrical interfaces with corresponding IP Protection are included. For harsh conditions of use in aggressive seawater our cylinders feature the piston rod coating from Ceramax Engineered Coatings, based on the latest oxide coating (plasma).Hydraulics in Special ApplicationsArctic temperatures, extreme con-ditions in relation to pressure in the deep seas, hazardous situa-tions in environments at risk from explosions – everywhere Rexroth components developed specially for your application operate auto-matically, safely and reliably.Special Projects for deep sea applications Deep water projects place particu-lar demands on the components as regards pressure and temperature ratios. Rexroth offers specially designed valves and components for pressure-compensated sub-oil application. With these, usage is possible down to a depth of 3,500 meters.Components for sub-zero temperature applicationsRexroth even supplies solutions and special technologies for use under the harshest conditions of the Arctic regions. These include special valves for open deck appli-cations at ambient temperatures of down to 50 °C below zero.Components in accordance with ATEX DirectivesIn close co-operation with the cus-tomer Rexroth has implemented complete drive and control solu-tions for areas at risk from explo-sions. The products used for this, such as valves, hydraulic cylinders and power units are produced and supplied under strict observance of the ATEX Directive 94/9/EG.8Example: Cargo Pump DriveThe requirements:Control concept for loading and unloading a bitumen and chemi- cal tanker in an area at risk from explosion. Depending on the me-dium to be conveyed, the housing and storage temperatures of the cargo pump, together with the suction and delivery pressure of the pump, must be variable. As bitumen has to be kept permanent-ly at a minimum temperature and circulated, a high level of avail- ability is required.The solution:Visualization via touch panel with bus link to PLC. Inputting of sensor technology in the field via intrinsically safe circuits is followed by processing in the PLC. Monitoring and control of hy-draulics, cooling and lubrication systems. Complete switching sys-tem designed for 300 KW in each case. In order to guarantee the required availability the complete system has been designed so as to be redundant.Control and Automation Technology – Everything to Hand on BoardComplete control and automation technology, along with co-ordi-nated power electronics – with our individual total concepts we offer solutions that provide for the future.Power component with PLC and isolating amplifierClassified Products Bosch Rexroth has decades of experience in working with Clas-sification Societies. Test engi-neers from all the well-known classification societies conductregular acceptance tests at our premises.Rexroth components meet the strict specifications of the Classi-fication Societies as regards design principles, the selection of mate-rials and environmental require-ments for the electronic compo-nents. Right at the beginning of the project the test criteria that are to be observed are defined together with the test engineer. Collabora-tion with the customer at an early stage guarantees that the project runs smoothly and on schedule. Examples of type-tested componentsA4V PumpAxial piston variable displacement pump with hp control for constant power, tested in accordance with Det Norske Veritas.Voith-Schneider propeller used as a ships’s propulsion: Bosch Rexroth supp-lies the system, approved by the Classifi-cation Society, for pitch adjustment of the VSP (power unit, control block and cylin-der).
