动力输出总成的设计(720转/分)摘要动力输出轴是拖拉机的重要工作部件,动力输出主要用于拖拉机在行进中输出发动机动力以驱动农机具,如割草机、喷药机等。
动力输出总成的设计是基于减速增扭的原理。
动力从变速箱引出,再进过一对大小齿轮减速,转速减小的同时,扭矩成比例的增加。
动力输出没有标准的设计过程,主要根据变速器和减速器的设计,确定齿轮的传动类型、传动关系、受力分析、建立数学模型。
依据传统的设计方法,本着半经验半理论的设计原则通过类比的方法,参考已有车型的动力输出的设计过程,然后验算零件的强度和机械应力情况,最后确定了采用半独立式的动力输出机构方案,动力直接从发动机的曲轴引出,这种输出类型现在被广泛使用,特别受到欧美的青睐。
本次设计采用的主动的直齿滑动齿轮啮合,主动齿轮可以在高速轴上滑动,以提供啮合和分离的选择。
这种设计最大的优点是结构简单,便于安装和维修。
而且为了避免动力输出轴头在高速旋转下危及人身的事故发生,本次设计专门设计了动力输出轴保护罩,保证外露的高速旋转部件不会伤害人,提高了使用的安全性。

At the same time ,the PTO shaft increases the torque ,for when speed is lost through gears, torque is gained in the same proportion . According to the design of the transmissions in consideration of the simplicity and reliability. According to the traditional mean of design, part experience and theory and analogism. We firstly chose gear type, make selection of the gear parameter, then establish the mathematic model dose the type of the being.In this thesis, we dose semi-independent type. This type of PTO shaft is popular not only in our country, but also in Europe. The merit of this type is outstanding, We choose spur gear to transmit the drive.the driving gear can be slid along the splines on the internal end of shaft and into mesh with driven gear. The means of this type is easy for fixing and mending.To avoid the accident of the wound from the revolving of the end of PTO shaft, the shaft and universal joint of PTO should be guarded by commercially available shields ,which cover moving part, so it will improve the softy.Key words:PTO shaft, semi-independent, driving gear, driven gear目录第一章绪论........ .. .. .. .. ..

汽车悬架原理外文文献及翻译(文档含中英文对照即英文原文和中文翻译)The rinciple Of Car SuspensionsBy William HarrisUniversity of MichiganWhen people think of automobile performance, they normally think of horsepower, torque and zero-to-60 acceleration. But all of the power generated by a piston engine is useless if the driver can't control the car. That's why automobile engineers turned their attention to the suspension system almost as soon as they had mastered the four-stroke internal combustion engine.The job of a car suspension is to maximize the friction between the tires and the road surface, to provide steering stability with good handling and to ensure the comfort of the passengers. In this article, we'll explore how car suspensions work, how they've evolved over the years and where the design of suspensions is headed in the future.1.Vehicle DynamicsIf a road were perfectly flat, with no irregularities, suspensions wouldn't be necessary. But roads are far from flat. Even freshly paved highways have subtle imperfections that can interact with the wheels of a car. It's these imperfections that apply forces to the wheels. According to Newton's laws of motion, all forces have both magnitude and direction. A bump in the road causes the wheel to move up and down perpendicular to the road surface. The magnitude, of course, depends on whether the wheel is striking a giant bump or a tiny speck. Either way, the car wheel experiences a vertical acceleration as it passes over an imperfection.Without an intervening structure, all of wheel's vertical energy is transferred to the frame, which moves in the same direction. In such a situation, the wheels can lose contact with the road completely. Then, under the downward force of gravity, the wheels can slam back into the road surface. What you need is a system that will absorb the energy of the vertically accelerated wheel, allowing the frame and body to ride undisturbed while the wheels follow bumps in the road.The study of the forces at work on a moving car is called vehicle dynamics, and you need to understand some of these concepts in order to appreciate why a suspension is necessary in the first place. Most automobile engineers consider the dynamics of a moving car from two perspectives:1)Ride - a car's ability to smooth out a bumpy road2)Handling - a car's ability to safely accelerate, brake and cornerThese two characteristics can be further described in three important principles - road isolation, road holding and cornering. The table below describes these principles and how engineers attempt to solve the challenges unique to each.A car's suspension, with its various components, provides all of the solutions described.2.The Chassis SystemThe suspension of a car is actually part of the chassis, which comprises all of the important systems located beneath the car's body.These systems include:1)T he frame - structural, load-carrying component that supports the car's engine and body, which are in turn supported by the suspension2)T he suspension system - setup that supports weight, absorbs and dampens shock and helps maintain tire contact3)T he steering system - mechanism that enables the driver to guide and direct the vehicle4)T he tires and wheels - components that make vehicle motion possible by way of grip and/or friction with the roadSo the suspension is just one of the major systems in any vehicle.With this big-picture overview in mind, it's time to look at the three fundamental components of any suspension: springs, dampers and anti-sway bars.figure 2-1 Chassis3.SpringsToday's springing systems are based on one of four basic designs:1)Coil springs - This is the most common type of spring and is, in essence, a heavy-duty torsion bar coiled around an axis. Coil springs compress and expand to absorb the motion of the wheels.2)Leaf springs - This type of spring consists of several layers of metal (called "leaves") bound together to act as a single unit. Leaf springs were first used on horse-drawn carriages and were found on most American automobiles until 1985. They are still used today on most trucks and heavy-duty vehicles.3)Torsion bars - Torsion bars use the twisting properties of a steel bar to provide coil-spring-like performance. This is how they work: One end of a bar is anchored to the vehicle frame. The other end is attached to a wishbone, which acts like a lever that moves perpendicular to the torsion bar. When the wheel hits a bump, vertical motion is transferred to the wishbone and then, through the levering action, to the torsion bar. The torsion bar then twists along its axis to provide the spring force. European carmakers used this system extensively, as did Packard and Chrysler in the United States, through the 1950s and 1960s. 4)Air springs - Air springs, which consist of a cylindrical chamber of air positioned between the wheel and the car's body, use the compressive qualities of air to absorb wheel vibrations. The concept is actually more than a century old and could be found on horse-drawn buggies. Air springs from this era were made from air-filled, leather diaphragms, much like a bellows; they were replaced with molded-rubber air springs in the 1930s.Based on where springs are located on a car -- i.e., between the wheels and the frame -- engineers often find it convenient to talk about the sprung mass and the unsprung mass.4.Sprung and Unsprung MassThe sprung mass is the mass of the vehicle supported on the springs, while the unsprung mass is loosely defined as the mass between the road and the suspension springs. The stiffness of the springs affects how the sprung mass responds while the car is being driven. Loosely sprung cars, such as luxury cars (think Lincoln Town Car), can swallow bumps and provide a super-smooth ride; however, such a car is prone to dive and squat during braking and acceleration and tends to experience body sway or roll during cornering. Tightly sprung cars, such as sports cars (think Mazda Miata), are less forgiving on bumpy roads, but they minimize body motion well, which means they can be driven aggressively, even around corners.So, while springs by themselves seem like simple devices, designing and implementing them on a car to balance passenger comfort with handling is a complex task. And to make matters more complex, springs alone can't provide a perfectly smooth ride. Why? Because springs are great at absorbing energy, but not so good at dissipating it. Other structures, known as dampers, are required to do this.5.Shock AbsorbersUnless a dampening structure is present, a car spring will extend and release the energy it absorbs from a bump at an uncontrolled rate. The spring will continue to bounce at its natural frequency until all of the energy originally put into it is used up. A suspension built on springs alone would make for an extremely bouncy ride and, depending on the terrain, an uncontrollable car.Enter the shock absorber, or snubber, a device that controls unwanted spring motion through a process known as dampening. Shock absorbers slow down and reduce the magnitude of vibratory motions by turning the kinetic energy of suspension movement into heat energy that can be dissipated through hydraulic fluid. To understand how this works, it's best to look inside a shock absorber to see its structure and function.A shock absorber is basically an oil pump placed between the frame of the car and the wheels. The upper mount of the shock connects to the frame (i.e., the sprung weight), while the lower mount connects to the axle, near the wheel (i.e., the unsprung weight). In a twin-tube design, one of the most common types of shock absorbers, the upper mount is connected to a piston rod, which in turn is connected to a piston, which in turn sits in a tube filled with hydraulic fluid. The inner tube is known as the pressure tube, and the outer tube is known as the reserve tube. The reserve tube stores excess hydraulic fluid.When the car wheel encounters a bump in the road and causes the spring to coil and uncoil, the energy of the spring is transferred to the shock absorber through the upper mount, down through the piston rod and into the piston. Orifices perforate the piston and allow fluid to leak through as the piston moves up and down in the pressure tube. Because the orifices are relatively tiny, only a small amount of fluid, under great pressure, passes through. This slows down the piston, which in turn slows down the spring.Shock absorbers work in two cycles -- the compression cycle and the extension cycle. The compression cycle occurs as the piston moves downward, compressing the hydraulic fluid in the chamber below the piston. The extension cycle occurs as the piston moves toward the top of the pressure tube, compressing the fluid in the chamber above the piston. A typical car or light truck will have more resistance during its extension cycle than its compression cycle. With that in mind, the compression cycle controls the motion of the vehicle's unsprung weight, while extension controls the heavier, sprung weight.All modern shock absorbers are velocity-sensitive -- the faster the suspension moves, the more resistance the shock absorber provides. This enables shocks to adjust to road conditions and to control all of the unwanted motions that can occur in a moving vehicle, including bounce, sway, brake dive and acceleration squat.6.Struts and Anti-sway Barsfigure 6-1 Common strut designAnother common dampening structure is the strut -- basically a shock absorber mounted inside a coil spring. Struts perform two jobs: They provide a dampening function like shock absorbers, and they provide structural support for the vehicle suspension. That means struts deliver a bit more than shock absorbers, which don't support vehicle weight -- they only control the speed at which weight is transferred in a car, not the weight itself.Because shocks and struts have so much to do with the handling of a car, they can be considered critical safety features. Worn shocks and struts can allow excessive vehicle-weight transfer from side to side and front to back. This reduces the tire's ability to grip the road, as well as handling and braking performance.7.Anti-sway BarsAnti-sway bars (also known as anti-roll bars) are used along with shock absorbers or struts to give a moving automobile additional stability. An anti-sway bar is a metal rod that spans the entire axle and effectively joins each side of the suspension together.When the suspension at one wheel moves up and down, the anti-sway bar transfers movement to the other wheel. This creates a more level ride and reduces vehicle sway. Inparticular, it combats the roll of a car on its suspension as it corners. For this reason, almost all cars today are fitted with anti-sway bars as standard equipment, although if they're not, kits make it easy to install the bars at any time.8.The Future of Car SuspensionsWhile there have been enhancements and improvements to both springs and shock absorbers, the basic design of car suspensions has not undergone a significant evolution over the years. But all of that's about to change with the introduction of a brand-new suspension design conceived by Bose -- the same Bose known for its innovations in acoustic technologies. Some experts are going so far as to say that the Bose suspension is the biggest advance in automobile suspensions since the introduction of an all-independent design.How does it work? The Bose system uses a linear electromagnetic motor (LEM) at each wheel in lieu of a conventional shock-and-spring setup. Amplifiers provide electricity to the motors in such a way that their power is regenerated with each compression of the system. The main benefit of the motors is that they are not limited by the inertia inherent in conventional fluid-based dampers. As a result, an LEM can extend and compress at a much greater speed, virtually eliminating all vibrations in the passenger cabin. The wheel's motion can be so finely controlled that the body of the car remains level regardless of what's happening at the wheel. The LEM can also counteract the body motion of the car while accelerating, braking and cornering, giving the driver a greater sense of control.Unfortunately, this paradigm-shifting suspension won't be available until 2009, when it will be offered on one or more high-end luxury cars. Until then, drivers will have to rely on the tried-and-true suspension methods that have smoothed out bumpy rides for centuries.汽车悬架的原理当人们考虑汽车性能的时候,他们通常认为是马力,扭矩和零到60的加速时间。

大学生F1方程式赛车整车设计毕业论文大学生F1方程式赛车整车设计摘要本文基于汽车理论课程实践所做的BAJA赛车模型,并结合FSAE 赛车比赛规则和赛道的布置特点,进行拓展设计一款大学生F1方程式赛车。
从赛车底盘角度出发,本文侧重于汽车车架的设计,因为车架是整车的重要组成部分,它不仅承受着来自路面的各种复杂载荷,同时也是其他总成的安装载体。
通过有限元法对车架结构进行分析,对提高整车的各种性能有重要的意义。
本文根据《中国FSC大赛规则(2012)》要求,首先利用UG6.0软件对赛车车架进行结构设计,建立起多个车架的三维模型,然后将设计出来的多个车架以及BAJA模型的车架导入到有限元软件中,对车架进行静力学分析,通过对比静力和应力分布图分析选出更优秀的车架。
同时对Formula SAE赛车的发动机系统、车轮系统、传动系统、悬架系统、转向系统、制动系统等进行选型和整体布置,然后根据所选的总成参数对整车动力性能进行匹配以及整车动力性能进行分析,从而设计出一款符合大赛要求同时性能优异的赛车。
关键词:UG,大学生F1方程式赛车,车架,有限元分析,动力匹配Formule SAE Collegiate Design of The Racing CarABSTRACTThe article is Based on the BAJA racing car model which is made at the Practice of Automobile Theory Course , and at the same time with combinations of the FSAE car racing game rules and the circuit layout characteristics, to expand the design of a formula sae race car. Start from the chassis of the car , this article focuses on the design of automobile frame, because the frame is an important part of vehicle, it not only suffered from a variety of complex surface load, at the same time it is the carrier to installthe other assembly.

外文文献原稿和译文原稿A New Type Car -- Hybrid Electric VehicleWith skyrocketing fuel prices and changes in weather patterns, many car manufacturers claimed to develop the kind of vehicles that will increase the mileage and reduce the emissions. Hybrid car is a kind of vehicle which can meet above requirements. A hybrid car features a small fuel-efficient gas engine combined with an electric motor that assists the engine.The reasons of building such a complicated machine are twofold: to reduce tailpipe emissions and to improve mileage. Firstly, hybrid cars are good for the environment. They can reduce smog by 90 percent and they use far less gasoline than conventional cars. Meanwhile, hybrid cars burn less gasoline per mile, so they release fewer greenhouse gases. Secondly, hybrid cars are economical. Hybrid cars, which run on gas and electricity, can get up to 55 to 60 miles per gallon in city driving, while a typical SUV might use three times as much gas for the same distance! There are three reasons can mainly account for that: 1) Hybrid engines are much smaller than those on conventional cars. A hybrid car engine is to accommodate the 99% of driving time when a car is not going up hills or accelerating quickly. When extra acceleration power is needed, it relies on the battery to provide additional force. 2) Hybrid gasoline engine can shut off when the car is stopped and run off their electric motor and battery.3) Hybrid cars often recover braking energy. Electric motors could take the lost kinetic energy in braking and use it to charge the battery. Furthermore, hybrids are better than all-electric cars because hybrid car batteries recharge as you drive so there is no need to plug in. Most electric cars need to be recharged every 50-100miles. Also, most electric cars cannot go faster than 50-60 mph, while hybrids can.Hybrid cars bridge the gap between electric and gasoline-powered cars by traveling further and driving faster and hybrid gas-electric cars are proving to be a feasible alternative at a time of high gas prices. So, in my opinion, hybrid cars will have a bright future.How Does Hybrid Electric Vehicle Work?You probably own a gasoline or diesel-engine car. You may have heard of electric vehicles too. A hybrid vehicle or hybrid electric vehicle (HEV) is a combination of both. Hybrid vehicles utilize two or more sources of energy for propulsion. In the case of HEVs, a combustion engine and an electric motor are used.How it works depends on the type of drive train it has. A hybrid vehicle can either have a parallel or series or parallel-series drive train.Parallel HybridThe parallel hybrid car has a gas tank, a combustion engine, transmission,electric motor, and batteries.A parallel hybrid is designed to run directly from either the combustion engine or the electric motor. It can run using both the engine and the motor. As a conventional vehicle, the parallel hybrid draws its power from the combustion engine which will then drive the transmission that turns the wheels. If it is using the electric motor, the car draws its power from the batteries. The energy from the batteries will then power the electric motor that drives the transmission and turns the wheel.Both the combustion engine and the electric motor are used at the same time during quick acceleration, on steep ascend, or when either the engine or the motor needs additional boost.Since the engine is directly connected to the wheels in a parallel drive train, it eliminates the inefficiency of converting mechanical energy into electrical energy and back. This makes a very effective vehicle to drive on the highway.Series HybridThe series hybrid car also has a gas tank, a combustion engine, transmission, electric motor, and batteries with the addition of the generator. The generator can be the electric motor or it can be another separate component.The series configuration is the simplest among the 3. The engine is not connected to the transmission rather it is connected to the electric motor. This means that the transmission can be driven only by the electric motor which draws its energy from the battery pack, the engine or the generator.A hybrid car with a series drive train is more suited for city driving conditions since the engine will not be subjected to the varying speed demands (stop, go, and idle) that contributes to fuel consumption.Series-Parallel HybridThe series-parallel configuration solves the individual problems of the parallel and series hybrid. By combining the 2 designs, the transmission can be directly connected to the engine or can be separated for optimum fuel consumption. The Toyota Prius and the Ford Escape Hybrid use this technology.Honda’s hybridFor those of you who have toyed with the idea of buying a hybrid but were discouraged by the price, you are not alone. In fact, despite the growing concern for the environment, not to mention the skyrocketing price of gas, hybrid cars still only represent a small percentage of global car sales, and a major reason for this is the cost.Hybrids are considered the wave of the future because they not only reduce emissions, addressing the issue of climate change, but they get great gas mileage, an important consideration with the current price of oil. It should be noted that hybrids can also improve the power of the engine, which compromises any advantages in fuel efficiency and emissions. Whatever the application, however, the technology makes the cars more expensive.Because of this, they are the vehicle of choice for only a small niche of people who can afford them, and they currently enjoy a special status amongst the image conscious celebrity-set. For most average consumers, however, they are not an option.That may soon change.Honda Motor Corporation, one of the largest car manufacturers in the world and a leader in fuel efficient technology, has unveiled it’s plan to introduce a low-cost hybrid by 2009. If they can pull it off, they hope to make the hybrid a more mainstream car that will be more appealing to the general public, with the ultimate goal of achieving greater sales and broader appeal than their current incarnation.This, of course, is making Detroit nervous, and may signal a need for American car makers to start making greener and more fuel efficient vehicles, something they could afford to ignore in the past because hybrid cars weren’t worth their attention (due to such a small market share) while gas-guzzling SUVs have such high profit margins.Honda, meanwhile, has had to confront a growing need to compete with Toyota, which has not only grown to be the world’s largest automaker, but makes the car that has become synonymous with the hybrid movement, the Prius. Honda is therefore faced with the seemingly insurmountable task of challenging Toyota’s dominance in the market.Concurrently, Toyota is racing to lower production costs on the Prius, as well, which would hopefully result in a lower cost to the consumer. All eyes are on a potentially favorable car buyers market in 2009.In the meantime, with even adamant global warming naysayers warming up (no pun intended) to the possibilities of an ecological disaster on the horizon, maybe it’s time that we got over our need to drive huge SUVs and start moderating our fuel consumption.Then again, as gas prices hovering around $4.00 and with no ceiling in sight, we may have little choice in the matter.Engine Operating PrinciplesMost automobile dngines are internal combustion, reciprocating 4-stroke gasoline engines, but other types have been used, including the diesel, the rotary ( Wankel ) , the 2-srtoke, and stratified charge.Reciprocating means up and down or banck and forth, It is the up and down action of a piston in the cylinder blick, or engine block. The blick is an iron or aluminum casting that contains engine cylinders and passges called water jackets for coolant circulation. The top of the block is covered with the cylinder head. Which forms the combustion chanber. The bottom of the block is covered with an oil pan or oil sump.Power is produced by the linear motion of a piston in a cylinder. However, this linear motion must be changed into rotary motion to turn the wheels of cars of trucks. The piston is attached to the top of a connecting rod by a pin, called a piston pin or wrist pin. The bottom of the connecting rod is attached to the crankshaft. The connecting rod transmits the up-and-down motion of the piston to the crankshaft, which changes it into rotary motion.The connecting rod is mounted on the crankshaft with large beaings called rodbearings. Similar bearings, called main bearings, are used to mount the crankshaft in the block. Shown in Fig. 1-1The diameter of the cylinder is called the engine bore. Displacement and compression ratio are two frequently used engine specifications. Displacement indicates engine size, and compression ratio compares the total cylinder volume to compression chamber volume.The term stroke is used to describe the movement of the iston within the cylinder, as well as the distance of piston travel. Depending on the type of engine the operating cycle may require either two or four strokes to complete. The 4-stroke engine is also called Otto cycle engine, in honor of the German engineer, Dr. Nikolaus Otto, who first applied the principle in 1876. In the 4-stroke engine, four strokes of the piston in the cylinder are required to complete one full operating cycle. Each stroke is named after the action it performs intake, compression, power, and exhaust in that order, shown in Fig1-2.1、Intake strokeAs the piston moves down, the vaporized mixture of fuel and air enters the cylinder through open intake valve. To obtain the maximum filling of the cylinder the intake valve opens about 10°before t.b.c., giving 20°overlap. The inlet valve remains open until some 50°after b.d.c. to take advantage of incoming mixture.2、 Compression strokeThe piston turns up, the intake valve closes, the mixture is compressed within the combustion chamber, while the pressure rise to about 1Mpa, depending on various factors including the compression ratio, throttle opening and engine speed. Near the top of the stroke the mixture is ignited by a spark which bridges the gap of the spark plug.3、 Power strokeThe expanding gases of combustion produces a rise in pressure of the gas to some 3.5Mpa, and the piston is forced down in the cylinder. The exhaust valve opens near the bottom of the stroke.4、Exhust strokeThe piston moves back up with the exhaust valve open some 50°before b.d.d., allowing the pressure within the cylinder to fall and to reduce ‘back’pressure on the piston during the exhaust stroke, and the burned gases are pushed out to prepare for the next intake stroke.The intake valve usually opens just before the exhaust stroke. This 4-stroke cycle is continuously repeared in every as long as the engineremains running.A 2-stroke engine also goes through four actions to complete one operating cycle.However, the intake and the compression actions are combined in one seroke, and the power and exhaust actions are combined in the other stroke. The term2-stroke cycle or 2-stroke is preferred to the term 2-cycle, which is really not accurate.In automobile engines, all pistons are attached to a single crankshaft. The more cylinders an engine has, the more power strokes produced for cach revolution. This means that an 8-cylinder engine runs more smoothly bdcause the power atrokes arecloser together in time and in degrees of engine rotation.The cylinders of multi-cylinder automotive engines arranged in one of three ways. 1、Inline engines use a single block of cylinder.Most 4-cylinder and any 6-cylinder engines are of this design. The cylinders do not have to be vertical. They can be inclined either side.2、V-type engines use two equal bands of cylinders, usually inclined 60degrees or 90degrees from the cach other. Most V-type engines have 6 or 8 cylinders, although V-4 and V-12 engines have been built.3、Horizontally opposed or pancake engines have two equal banks of cylinders 180degreeas apart. These space saving engine designs are often air-cooled, and are found in the Chevrolet Carvair, Porsches, Subaus, and V olkswagens. Subaus design is liquid cooled.Late-model V olkswagen vans use a liquid-cooled version of the air cooled VWhorizontally opposed engine.译文新型汽车----混合动力汽车在油价飞涨的今天,汽车制造商被要求发展一种排放低,行驶里程长的汽车。

Design of an SAE Baja Racing Off-Road Vehicle PowertrainI was fortunate enough to be able to lead powertrain design on the Baja team for two years in a row, which allowed me to not only test theories and modify them, but also to learn from mistakes. A brief review of the 2014 car powertrain design is in order, as it informs many of the design decisions made for the 2015 Baja car.The 2014 Akron Baja Car (ZB14) uses a Comet 780 series CVT coupled to a two stagechain reduction to couple the Engine to the 22 inch diameter tires. The layout of this chain reduction was designed with two things in mind. First, there was a desire to see the acceleration benefits of raising the Engine higher in the car, thus raising the center of mass of the car and the subsequent longitudinal weight transfer during acceleration. This increase in longitudinal weight transfer would theoretically provide more tractive ability for the rear tires during an acceleration run. The second objective of the chain layout was to reduce the wheelbase as much as possible.We found that there was not too much benefit gained by the increased height of the center of gravity during acceleration. In addition, the negative effect this higher center of gravity had on lateral handling and rollover completely outweighs any positive acceleration effects gained by a raised engine. Ideally, the bottom of the engine should be placed as low as possible for the best handling car. The shorter wheelbase accomplished with the unique packing of the driveline did help with navigating tight obstacles in maneuverability, as demonstrated by our 22nd finish in maneuverability at the 2014 competition in Illinois (See results compilation in appendix for full placement details).This car was also used to verify the effectiveness of the gear reduction ratio calculated from theory that will presented later in this report. From this testing it was found that only a slight modification to the originally calculated gear ratio was necessary to reach a well performing vehicle.Chain Drive versus Spur Gear DriveBefore the design of the powertrain for the 2015 Akron Zips Baja Racecar (ZB15) could begin, an important decision needed to be made. This decision was whether to use an uncovered chain reduction similar to ZB14 or to use an enclosed, continuously-lubricated spur gearbox. Both selections have strengths and weaknesses and each aspect of what makes a sound Baja powertrain must be examined to determine which type is better. Each of the categories that will serve as the performance metrics bywhich to compare the transmission types will be measured on a scale from 1 to 5. If a transmission type receives a 5 in any particular category, it will mean that that particular transmission type fulfills that performance metric better than any other transmission type known to this application.As weight is of overwhelming pertinence in a racing application, it must be the first metric under consideration. The double chain reduction has been shown to be a lightweight setup, but requires many heavy mounting tubes on the frame in its original configuration. A preliminary survey of teams with well-tested single-speed gearboxes shows that an optimized weight for gears and gear case is around 12-15 pounds. Combining this with 30 pounds for the CVT/belt and 50 pounds for the engine yields an approximate transmission weight (ignoring CV axles) of roughly 92-95 pounds. This is in comparison to the 109.46 pounds that the transmission on the Akron Baja 2014 car weighed in at. However, some consideration must be made that this gearbox would be a first iteration for our team, so we must add at least 10 to 15 pounds in order to be conservative until welearn how to make gears well. Even with the extra conservatism, the gear drive will receive a rating of 4 for weight while the chain drive receives a rating of 3 for weight.CostChain drives are very common for this type of application in the industry. For example, most lawn equipment and ATVs will use a chain or belt drive as a primary means of power. For this reason, commercially available parts make constructing a chain-drive transmission cheap and quick. For this reason, the double chain reduction of the ZB14 racecar receives a rating of 5 for cost. Lightweight, racing spur gears are typically “one off” jobs that are highly labor intensive. This is because the face width of the gear is not necessary throughout the web of the gear, so plenty of machining must be done to optimize weight. Gears must also be heat treated to provide acceptable tooth performance, which adds in addition cost and time. For these reasons, a spur gear reduction receives a rating of 2 in cost for a Baja racing application. Design SimplicityFor chain drives, much of what comes commercially available needs no modifications to be ready for service on a Baja car. This makes for a transmission that is more “plug-and-play” than a spur gear drive. Chain drives also have the advantage of many teeth on a sprocket sharing load, such that teeth may be very small and sprockets may be made out of low quality steel. For a gear drive,only one tooth on eachpinion/gear is carrying the load much of the time, so great care must be exercised in designing the teeth properly. In addition to additional complexity of a spur gearbox in loading, appropriate center-to-center distances between shafts are more complicated and need to be much more precise on a spur gear drive. On a chain drive, any errors in center-to-center distances may be easily accommodated by creating a longer or shorter chain. However, on a spur gear drive, even an error of .030 inches could be deadly to the proper meshing of spur gears. For this reason, the chain reduction receives a rating of 5 when considering design simplicity, and the gear drive receives a 3.FamiliarityObviously, since a chain drive has always been used on Akron Baja teams, and a spur gear reduction has never (or has rarely) been used, the chain drive receives a rating of 5 while the spur gear reduction receives a rating of 3.Ease of ManufactureThe metric ease of manufacture comes in two parts. The first part is the ease by which the rotating components of the transmission may be manufactured. The second is the ease by which the components may be attached to the chassis of the vehicle. For the chain reduction, component machining was simple. It only took some simple lathe and mill work to manufacture the required shafts and hubs. However, the chain reduction of the ZB14 car required a very intricate setup on the chassis to accommodate each of the rotating shafts. The spur gearbox required plenty of CNC (Computer numerical control) machining not only to lighten the gears, but also to manufacture the housing which would surround the gears and contain bearings. On the other hand, the gearbox mounts into the car with simply two bolts. In summary, chain drives require more intricate mounting on the chassis itself while requiring less machining work to manufacture. Furthermore, gear drives require much more complex machining while their mounting schemes into a cha ssis may be much simpler. Thus, in terms of ease of manufacture, we rate ZB14’s chain reduction 4 and the spur gear reduction 5.LubricationProperly lubricating metal surfaces which are in sliding or rolling contact is of great interest in engines and transmissions. This aspect of transmission design is something that design judges at competition regard as sacred. The chain reduction setup of ZB14 was not protected from dirt and mud, and was therefore acceptable to increased wear from the elements. This was seen as a major downfall of the design of thesystem by judges at competition. A spur gear reduction, when properly designed, has a gear case which has an oil bath which continuously lubricates the gears during operation. This extends the life of metal surfaces and can, with the right oil, allow even smaller face widths than with a lower quality oil. Because of the great weight placed on this aspect of the transmission at competition, the spur gear reduction earns a rating of 5 while the double chain reduction earns a 1.Powertrain EfficiencyFor a chain reduction, studies on bicycle roller chain have shown average efficiencies of roughly 92-95% [1]. For an external spur gear reduction, the efficiency associated with each gear set meshing is normally in the range of 97-99% [2]. Assuming that the efficiency of the rubber belt CVT and final drive Rzeppa joint axles are 94% .It is clear from this equation that a spur gear reduction is far more efficient than a chain reduction. For this reason, the chain reduction of the ZB14 is rated 2 for powertrain efficiency and the spur gear drive is rated 4. Note that the spur gear drive, once optimized for fluid bath level, heat treatment (distorting teeth), and shaft misalignments, would be rated 5. However, with our first year design we must account for errors in mesh losses and fluid churning losses associated with a new design.PackagingIn the ZB14 chain reduction, center-to-center distances had to be large to avoid excessively large chain angle with respect to the line connect the centers of the shafts. If this angle were to become very large, the number of teeth that were carrying the load on the smaller sprocket would become less and potentially cause sprocket damage. With a spur gear reduction, center-to-center distances are small and the gears can be oriented in a way which optimizes space usage, without concern of the necessity to tension chains. For this reason, the chain reduction receives a rating of 3 for packaging while the spur gear reduction receives a rating of 5.ServiceabilityThe term serviceability in this category refers to the ease by which rotating parts may be removed from the driveline, replaced, and then put back onto the car. The chain reduction involves the de-tensioning of chains and bolts which hold bearing housings to the chassis, making for roughly 2 hours of work to swap everything on the system. The spur gear reduction will obviously involve draining of transmission fluid,removal of the gearbox from the car, separation of the gearbox, replacing components, and then re-sealing the gearbox, a process that could take up to 12 hours. However, with some clever design work, components which need to be removed often, such as axles and CVT pulleys, may be designed in such a ways as to allow their removal without removing the gearbox itself. The internal components of the gearbox, however, will always be more difficult to replace than the components of a chain drive. For this reason, the chain drive receives a score of 4 in serviceability while the spur gear reduction receives a score of 3.SafetyOperator safety is always a huge concern, whether you are at a Baja competition or in the industry. The safest transmission would not allow any accidents to happen during operation. Clearly, with a stationary gear case surrounding rotating gears of the transmission, a bystander is not likely to get his/her hands caught amongst rotating components. However, with the chain reduction of ZB14, even with the chain guards in place, it is still possible to injure oneself with some degree of ease on the rotating components (or the sharp-edged chain guards themselves). Moreover, if a piece of some rotating component were to become detached from the drivetrain during operation, a gear case is much more likely to contain the wreckage than chain guards, making it safer. For these reasons, the double chain reduction receives a score of 2 for safety while the spur gear reduction earns a 5.Final ResultsThe spur gear reduction has emerged victorious! Observing table 2 below, we see by the final tally of the design decision matrix that the spur gear reduction is a more optimal design Transmission Design DecisionsTesting: Engine Dynamometer W.O.T. PerformanceAfter the preliminary hardware selection stage, a powertrain designer’s next point of interest is in designing the appropriate gear ratios that the vehicle will need to perform. These gear ratios will inevitably, after some hardware tuning during setup, allow maximum performance usage of the internal combustion engine. It then follows that a comprehensive understanding of how the engine performs over its rotational speed spectrum is absolutely critical to the aspiring powertrain designer.Baja动力总成设计连续几年,这使我不仅可以测试理论和修改它们,还要学习从错误。
