（二）底盘
底盘作用是支承、安装汽车发动机及其各部件、总成,形成汽车的整体造型,并接受发动机的动力,使汽车产生运动,保证正常行驶.底盘由传动系、行驶系、转向系和制动系组成.
1、传动系
传动系由离合器、变速器、万向传动装置和驱动桥组成,用来将发动机输出的动力传给驱动轮,并使之适合与汽车行驶的需要.
离合器固定于发动机飞轮后端面,并和变速器相连.离合器经常处于接合状态.当驾驶员踩下离合器踏板时,离合器分离,动力传递中断,以便进行起步、换档和制动等项作业.离合器还可通过打滑对传动系实行过载保护.
变速器上设有若干个前进挡和一个倒挡,各挡传动比都不相同,可以满足汽车在不同行驶阻力和不同车速下的需要.倒挡可以使汽车实现倒驶.“空挡”可以将动力传递中断.
万向传动装置位于变速器和驱动桥之间,将变速器输出的动力传至驱动桥.
驱动桥由主减速器、差速器、半轴和桥壳组成,其中有一个桥（多半是后桥）是驱动桥,驱动汽车,而另一个桥（多半是前桥）为从动桥,不起驱动作用.但越野汽车所有的车桥都是驱动桥,因此在变速器后面设有分动器,负责向各桥分配动力.
2、行驶系
行驶系是汽车的基础,由车架、车桥、车轮与轮胎以及位于车桥和车架之间的悬挂装置组成.车架是汽车的装配基体,将整个汽车装成一体.车桥与车轮负责汽车的行驶,悬挂装置组成.车架是汽车的装配基体,将整个汽车装成一体.车桥与车轮负责汽车的行驶,悬挂装置将车桥安装于车架,起到传力、导向和缓冲减震的作用.行驶系除影响汽车的操纵稳定性外,还对汽车的乘座舒适性起重要影响.
3、转向系
转向系用来改变或者恢复汽车的行驶方向.它是通过使前轮相对与汽车纵向平面偏转一定的角度来实现转向的.转向系主要由转向操纵机构、转向器和转向传动机组成.
4、制动系
制动系的作用是使行进中的汽车迅速减速直至停车,是停放的汽车可靠地驻留原地不动.行车制动装置由设在每个车轮上的制动器和制动操纵机构组成,由驾驶员通过制动踏板来操纵.驻车制动装置的制动器有装在变速器第二轴上的,但大多数是与后桥制动器合一的,驻车制动器由手操纵杆来操纵.
（三）车身
车身容纳驾驶员、乘客和货物,并构成汽车的外壳.载重汽车车身由驾驶室的货厢组成,客车与轿车的车身由统一的外壳构成.其他专用车辆还包括其他特殊装备等.车身还包括车门、窗、车锁、内外饰件、附件、座椅及车前各钣金件等.
（四）电器设备
电器设备由电源和用电设备组成.电源包括发电机和蓄电池.用电设备的内容很多,不同车型不太一样,主要有点火系、起动系、照明、仪表信号系统、空调以及其他用电设备等.

(B) chassis
Role is to support the chassis, engine and the installation of car parts, assembly, to form the overall shape of the car, and accept the power of the engine so that the sports car have to ensure normal traffic. The chassis by the power train, traveling system, steering and braking system components.
1, power train
By the power train clutch, transmission, universal joints and drive axle gear, the engine will be used to export power to the driving wheel, as well as to adapt with the car.
Clutch in the fixed-end after the engine flywheel and transmission and connected. Often in a state of clutch engagement. When the driver down the clutch pedal, clutch, power transmission interrupted for starting, braking and shifting operations items. Clutch can slip through the implementation of the transmission line overload protection.
Transmission has on a number of forward gear and a reverse gear, the gear transmission ratio is not the same as to meet the vehicle traveling at different speeds and under the resistance. Reverse gear can make the car drive down the achievement. "Gap" can interrupt transmission of power.
Universal gear transmission is located between the bridge and drive to the output of power transmission drives can be spread to the bridge.
Bridge drive from the main reducer, and differential and axle and axle housing, of which there is a bridge (most of the rear axle) is the drive axle, the car driver, and another bridge (most of the front axle) driven to the bridge , The role can not afford to drive. However, off-road vehicle drivers are all vehicular bridge at the bridge, the transmission in the back with sub-actuators, is responsible for the distribution of power to the bridge.
2, the Department of traveling
Department of motor vehicles traveling on the basis of the frame, Axles, wheels and tires and the vehicle-bridge is located between the frame and suspension components. Frame of a car assembly base, will be loaded into one vehicle as a whole. Axle and wheel responsible for driving the car, suspension components. Frame of a car assembly base, will be loaded into one vehicle as a whole. Axle and wheel responsible for driving the car, the suspension of vehicular bridge will be installed in the chassis, power-play, directed and shock absorption buffer. In addition to the impact of the Department of driving the vehicle handling and stability, but also for cars traveling in comfort plays an important influence.
3, to the Department of
Department to be used to restore or change the car's direction of travel. It is by making the front car with a relatively flat vertical deflection of a certain angle to the realization. To the main line to manipulation by the agencies, and the steering gear-shift composition of the motive.
4, braking system
The braking system is so moving up to the rapid deceleration of the vehicle to stop, the car is parked in the presence of a reliable stay put. Traffic in the brake on each wheel brakes and brake control agencies, through the brake pedal by the driver to manipulate. Parking brake brakes are installed in the transmission of the second axis, but most of the rear axle and brake-in-one, parking brake by hand to manipulate the joystick.
(C) body
Body to accommodate drivers, passengers and cargo, and constitute a case of motor vehicles. From the cab of the truck body Huoxiang, and the passenger of the car body constituted by the unification of Shell. Other special vehicles also includes other special equipment. Body also includes doors, windows, locks, internal and external accessories, accessories, car seats and the former sheet metal, and so on.
(D) electrical equipment
Electrical equipment from power and electricity equipment. Including power generators and batteries. The contents of a lot of electrical equipment, different models is not as mainly in the ignition system, starting system, lighting, instrument signal system, air-conditioning and other electricity equipment.
