Lesson 7 The Brakes
Lesson 7 TheBrakes The brakes may also be operated by mechanical linkages from the foot pedal and hand brake lever. mechanical linkage 机械连接 制动器也可以用制动踏板 制动手柄的机械制动装置操纵 制动踏板和 的机械制动装置操纵。 制动器也可以用制动踏板和制动手柄的机械制动装置操纵。 Common practice is to operate both front and rear brakes hydraulically with a secondary mechanical system operating the rear brakes only from the hand lever. 通常惯例是前、后制动器均为液压操纵，同时仅仅利用手柄的 仅仅利用手柄的辅助机 通常惯例是前、后制动器均为液压操纵，同时仅仅利用手柄的辅助机 械系统来操纵后制动器 来操纵后制动器。 械系统来操纵后制动器。 One of the great advantages of hydraulic operation is that the system is self-balancing, which means that the same pressure is automatically produced at all four brakes, whereas mechanical linkages have to be very carefully adjusted for balance. 液压操纵的最大优点之一是系统的自动平衡（自动调节） 液压操纵的最大优点之一是系统的自动平衡（自动调节），这就意味 着所有的四个制动器自动产生相等的压力， 着所有的四个制动器自动产生相等的压力，而机械传动装置必须经过 非常仔细的调整才能达到平衡。 非常仔细的调整才能达到平衡。

Part I Technical and Practical Reading
Passage A
Suspension Components
The components of the suspension system perform six basic functions: 1. Maintain correct vehicle ride height 2. Reduce the effect of shock forces 3. Maintain correct wheel alignment 4. Support vehicle weight 5. Keep the tires in contact with the road 6. Control the vehicle’s direction of travel
Figure 7-5
Shock Absorber
Shock absorber is a device that controls unwanted spring motion, which is important in keeping the tires in firm contact with the road. Shock absorbers control spring movements in both directions: when the spring is compressed and when it is extended. Without shock absorber, the spring will extend and release the energy which may allow the tires to lose contact with the road.

UNIT 7有许多不同类型的点火系统。
这些系统大多可以被置于三个不同的群体：传统的断路器点式点火系统（使用自20世纪初），电子点火系统（70年代中期以来，流行）和无分电器点火系统（介绍80年代中期）。
汽车点火系统有两个基本功能：它必须控制烧制，适用于不同的发动机要求的火花塞的火花和定时的，并且它必须增加电池电压到一个点，在那里将克服阻力所提供的火花塞间隙和火灾插头。
点式点火系统汽车点火系统分为两个电路- 初级和二次回路（图7-1）。
的主电路进行低电压。
此电路的工作，只在电池电流，并控制断路器分点火开关。
次级电路包括在线圈的次级绕组，分销商之间的高压导线的线圈（俗称线圈导线），分电器盖，分火头，火花塞引线和火花塞。
分配器的系统的控制元件。
切换初级电流和关闭，以及分配电流每次火花需要适当的火花塞。
分销商是一个固定的旋转轴周围的壳体。
通过分配器由发动机的凸轮轴驱动齿轮轴在一个半发动机转速驱动。
分配器轴的顶部附近有一凸轮发动机的每个气缸的一个肺叶。
的凸轮操作的接触点，它们被安装在分配器壳体内的一盘。
连接的转子到分配器轴的顶部。
时，分电器盖，在盖的中心在一个弹簧加载的金属片接触的转子上的金属带。
在转子的外端通过连接到火花塞的联系方式非常接近信息，分电器盖的外侧周围。
线圈（图7-2）是点火系统的心脏。
从本质上讲，它是什么以上的变压器，以相对低的电压（12伏）可从电池，增加一个点，它就会高达40,000伏火火花塞。
术语“线圈”也许是用词不当，因为实际上有两个线圈铁芯线绕约。
这些线圈是彼此绝缘的，并将整个装置是封闭在一个充满油的情况下。
重型线的圈数较少，初级线圈，它由被连接到位于在线圈顶部上的两个主端子。
次级线圈由多匝细线。
它是连接到连接的线圈的顶部（从分配器的线圈导线插入到塔）的高张力。
正常工作条件下，从电池的电源供给通过一个电阻器或向一次侧回路的线圈的电阻丝，然后通过在分配器的点火点（点）接地。
电池电压产生的激励线圈的初级电路的初级绕组，导致一个非常大的，强磁场的电流流过。

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。
Troubleshooting for Automatic

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.

For vehicles with non-adjustable rear suspensions, we can do as follows:
• Angle readings are measured at all four wheels.
Reading A
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.
