The diagram shows a very simple two-speed transmission in neutral. Let's look at each of the parts in this diagram to understand how they fit together: The input shaft comes from the engine through the clutch. The input shaft and the gear on it are connected as a single unit.
Clutch
In this article, we will learn why you need a clutch, and understand how the clutch in your car works. The reason of you need a clutch in the car is that the engine spins all the time, but the car wheels don't. In order for a car to stop without killing the engine, the wheels need to be disconnected from the engine somehow. The clutch allows us to smoothly engage a spinning engine to a nonspinning transmission by controlling the slippage between them.
Inter-mediate shaft are also connected as a single piece, so all of the gears on the inter-mediate shaft and the intermediate shaft itself spin as one unit. The input shaft and the inter-mediate shaft are directly connected through their meshed gears so that if the input shaft is spinning, so is the inter-mediate shaft . In this way, the inter-mediate shaft receives its power directly from the engine whenever the clutch is engaged. The gears 1 ride on bearings， so they spin on the output shaft. If the engine is off but the car is coasting, the output shaft can turn inside the gears1 while the gears1 and the inter-mediate shaft are motionless.

1. Description The steering system is the means by which the driver of a vehicle is able to control the position of the front wheels. The system must provide ease of handling, good directional control, and stability. This is achieved by the steering system in conjunction with the suspension system. (1) Manual steering ① Steering linkage The steering linkage includes the steering arms that are attached to the steering knuckle, tierods and tie-rod ends, adjusting sleeves and clamps, a center link (relay rod or drag link), an idler arm, and a pitman arm. There are the two most common types of steering linkage on passenger cars, shown in Fig.2-4-1 ball joints 球形接头 from side to side 从一端到 另一端 split 开口 clamp 夹紧 tie rod ends 横拉杆接 头

2 . Water Jacket
The water jacket is a collection of passages within the block and head. These passages let the coolant circulate around the “ hot spots ” ( valve seats and guides, cylinder walls, combustion chamber, etc. ) in order to cool them off. One interesting way to reduce the demands on the cooling system is to reduce the amount of heat that is transferred from the combustion chamber to the metal parts of the engine
Figure 4- 1 the cooling system of a water-cooled engine
1 . Water Pump
The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously.

Chapter 1 Automotive Basics（汽车基础）(1) Today s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: body, engine, chassis and electrical equipment 。
当今的车辆一般都由15000多个分散、独立且相互配合的零部件组成。
这些零部件主要分为四类：车身、发动机、底盘和电气设备。
1.1 Body（车身）(2) The body is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle.车身的设计要保证乘客安全舒适。
车身的款式使得汽车看起来漂亮迷人、色彩斑斓、时尚前卫。
1.2 Engine（发动机）(3)The internal combustion engine is most common: this obtains its power by burninga liquid fuel inside the engine cylinder. There are two types of engine: gasoline and diesel . Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the transmission .内燃机是最常见的，其动力来自气缸里液体燃料的燃烧。

1.Basic Parts of Steering System
The basic steering system (Figure 4-1) can be divided into three main assemblies:
·The spindle and steering arm assemblies. ·The linkage assembly connecting the steering arms and steering gear. ·The steering wheel, steering shaft, and steering gear assembly.
2. Types of Steering System There are two types of steering systems: manual steering and power steering systems. In the manual steering systems, driver does all the work of turning the steering wheel, steering gear, and tires. In the power steering systems, hydraulic or electric power-assisted steering is used to reduce the effort required by turning the steering wheel. There are three types of the steering gears in use: recirculating ball steering gear, worm-and-roller steering gear and rack-and-pinion steering gear. 3. Power Steering Systems Hydraulic lack-and-pinion power steering system. This system consists of mechanical rack-and-pinion steering gear, hydraulic working cylinders with working plungers, rotary slide valve, oil pump, pressure-limiting valve and oil reservoir (Figure 4-2).

Chapter 4 Steering and Suspension Systems
4.1 Steering System
Electro-hydraulic power steering system-Servotronic.
Servotronic is an electronically controlled rack-and-pinion steering system in which the hydraulic assisting forces are influenced by the driving speed. At low driving speeds, the full assisting force of the hydraulic rack-and pinion steering takes effect. The hydraulic assisting force is reduced as driving speed increases. So, Servotronic is a speed-sensitive power steering. Servotronic consists of electronic speedometer, ECU, hydraulic rack-and-pinion steering gear, oil reservoir, electro-hydraulic converter and oil pump (Figure 4-3).

4.1 Steering System
Electric power steering-Servolectric. With Servolectric
(Figure 4-4), the assisting force is generated by an electronically controlled electric motor. The electric motor is only switched on when required.
The steering torque applied by the driver is measured via a torsion rod with a torque sensor and in addition the speed is measured via a speed sensor. The two signals are fed to the ECU. The ECU calculates the torque required and its force-transfer direction using stored program maps and sends the relevant output signals to the electric motor. The latter generates an assisting torque which is transformed by a worm-gear pair and transmitted to the rack and-pinion steering gear.
