Automotive Chassis System

Nov 12, 2021

Automotive Chassis System

The automobile chassis is composed of four parts: transmission system, driving system, steering system and braking system. The role of the chassis is to support and install the car engine and its various parts and assemblies to form the overall shape of the car and receive the power of the engine to make the car move and ensure normal driving.

Transmission system Series

The transmission system is generally composed of clutch, transmission, universal transmission, main reducer, differential and half shaft.


The power from the car engine is transmitted to the driving wheels by the drive train. The drive train has the functions of deceleration, shifting, reversing, power interruption, wheel-to-wheel differential and shaft-to-axle differential. It works with the engine to ensure the normal driving of the car under various working conditions, and has good power and Economy.

Species composition

The transmission system can be divided into mechanical transmission, hydraulic transmission, hydraulic transmission, electric transmission, etc. according to different energy transmission methods

Brake system Series

A series of special devices used to make the outside world (mainly the road surface) exert a certain force on certain parts of the car (mainly the wheels) to perform a certain degree of forced braking are collectively called the braking system. Its function is to make the driving car decelerate or even stop forcibly according to the driver's request; make the stopped car park stably under various road conditions (including on the ramp); keep the speed of the car driving downhill stable.

Driving system Series

The driving system is composed of the frame, axle, wheels and suspension of the car. The frame, axle, wheels and suspension of a car form the driving system. The functions of the driving system are:

1. Accept the power of the drive shaft, and generate traction through the action of the driving wheel and the road, so that the car can drive normally;

2. Withstand the total weight of the car and the reaction force of the ground;

3. Alleviate the impact of uneven roads on the body, attenuate the vibration of the car in driving, and maintain the smoothness of driving;

4. Cooperate with the steering system to ensure the steering stability of the car
