What parts does the basic structure of a car include?

A car is mainly composed of four parts:

1, engine engine is the power plant of the car. Its function is to make the fuel burn to generate power, and then drive the wheels through the transmission system of the chassis to make the car run. There are two main types of engines: gasoline engines and diesel engines. A gasoline engine consists of a crank-connecting rod mechanism, a valve train, an oil supply system, a cooling system, a lubrication system, an ignition system and a starting system. The ignition mode of diesel engine is compression ignition, so there is no ignition system.

2. Chassis The function of the chassis is to support and install the automobile engine, its parts and assemblies, form the overall shape of the automobile, and accept the power of the engine to make the automobile move and ensure normal running. The chassis consists of four parts: transmission system, running system, steering system and braking system.

3. The car body is installed on the frame of the chassis for drivers and passengers to ride or load goods. The body of a car or bus is generally an integral structure, and the body of a truck is generally composed of a cab and a cargo box.

4. Electrical equipment Electrical equipment consists of power supply and electrical equipment. Power supply includes battery and generator. Electrical equipment includes the starting system of engine, the ignition system of gasoline engine and other electrical equipment.

An automobile is generally composed of four basic parts: engine, chassis, body and electrical equipment.

Automobile structure: divided into two parts: engine and chassis.

The engine is mainly composed of two mechanisms and five systems.

The function of transmission system: the power generated by the automobile engine is transmitted to the driving wheels through the transmission system.

Type and composition of transmission system: transmission system can be divided into mechanical transmission, hydraulic transmission, hydraulic transmission and electrical transmission according to different energy transmission modes.
