Unit 10 Anti-lock Brake System 汽车专业英语教学课件

Unit 10 Anti-lock Brake System
The anti-lock brake control module monitors the electromechanical components of the system.
Malfunction of the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
Unit 10 An brake booster. (3) Brake master cylinder. (4) Necessary brake tubes and hoses.
The anti-lock brake system consists of the following components: (1) Hydraulic Control Unit (HCU). (2) Anti-lock brake control module.
Unit 10 Anti-lock Brake System
Unit 10 Anti-lock Brake System
The ABS is a four-wheel system that prevents wheel lock-up by automatically modulating the brake pressure during an emergency stop. By preventing the wheels from locking, it enables the driver to maintain steering control and to stop in the shortest possible distance under most conditions[1].

由于暴露于空气中，盘式制动器的散热效果比鼓式 好。这意味着盘式制动器能持续使用更长的时间， 也就是说其抗热衰退性（因受热导致制动效能下降） 要好得多。
制动器效能因数 ：在制动鼓或制动盘的作用半径只上所得 到的摩擦力(Mp/R)与输入力Fo之比

In case of hydraulic braking force actuation, the brakes are applied by means of floating pressure pistons whose travel is not fixed, and which develop tensioning forces which are equal in both directions. One of the two shoes is the leading shoe, i.e. the frictional forces between the brake lining and the brake drum act to support the application force, whereas the frictional forces in the case of the trailing shoe act to oppose the tensioning force.
汽车从原地起步(静止)加速到某一速度需要能量，储存在汽 车中的那部分能量称为动能。要降低车速,制动器必须把动能 转换为热能；转换的速度决定了汽车减速的快慢。
A braking system consists of energy-supplying device, a control device, a transmission device and the brake.

Text A Battery




Charging and Discharging Principle (Fig.7.3) A battery charges and discharges electrical energy through the chemical reaction of the electrolyte. (a) Electrical energy is generated when the sulfuric acid of the electrolyte reacts with lead and turns into water. At this time, the sulfuric acid combines with the pole plates, causing the positive and negative pole plates to turn into lead sulfate. (b) Because sulfuric acid is discharged from the pole plates, the electrolyte turns into sulfuric acid, and the specific gravity of the electrolyte increases. The positive pole plates turn into lead dioxide and the negative pole plates turn into sponge lead.
Text C Charging System
Text A Battery

The starter battery supplies and stores the energy for the electrical systems in a motor vehicle. As it can be recharged, it is also referred to as an accumulator. The composition of a common battery is shown as Fig.7.2. When the engine is running, it stores the used electricity.

Task 1 Before reading the passage, see how much you know about wheel alignment. 1.Do you know what wheel alignment is? How often should a car be aligned? Reference 1
Reading A-2 A
Text
When the front wheels are not aligned to the rear thrust line, a common result would be that the vehicle would possibly “pull” to the side. This can happen from normal wear and stress, whether your vehicle has adjustable or nonadjustable rear suspension. To steer straight ahead, you would have to steer the front wheels slightly to the right.

To carry out orders from TCM, the automatic transmission has solenoid valves.
The transmission itself is very complicated. It consists of the following:
❖ 4、The hydraulic system which uses a special transmission fluid sent under pressure by an oil pump through the valve body to control the clutches and bands in order to command the planetary gear sets. 液压系统使用一种特殊的变速箱油，这种油通过油泵的压力， 经过阀体来传动，目的是控制离合器和制动带，以便指挥行 星齿轮排。

Transmission
Structure and components of automatic transmission
To input data, the automatic transmission needs various sensors such as VSS, TPS, input shaft speed sensor, output shaft speed sensor and transmission fluid temperature sensor. Also there is a gear switch that can input data such as P (park), R(rear), N(neutral) OD(overdrive), D(drive), 2, 1.
