What is the function of automobile chassis?

The function of automobile chassis is to support and install the automobile engine, its parts and assemblies, form the overall shape of the automobile, accept the power of the engine, make the automobile move and ensure the normal running.

Automobile chassis is another important part besides engine. The chassis is provided with a transmission system, a driving system, a steering system and a braking system. The transmission system is generally composed of clutch, transmission, universal transmission, main reducer, differential and half shaft. The function of the transmission system is to transfer the power of the automobile engine to the driving wheels through the transmission system. The transmission system has the functions of deceleration, speed change, commutation, power failure, wheel difference and axle difference. Working with the engine can ensure the normal running of the car under various working conditions, with good power and economy.

The drive consists of frame, axle, wheel and automobile suspension. The function of the driving system is to receive the power of the transmission system and generate traction through the action of the driving wheel and the road surface, so that the car can run normally; Bear the total weight of the car and the ground reaction force; Relieve the impact of uneven road surface on the car body, attenuate the vibration of the car when driving, and maintain the ride comfort.

The steering mechanism is mainly composed of steering wheel, steering shaft and steering column. The steering gear converts the rotation of the steering wheel into the swing of the steering rocker arm or the linear reciprocating motion of the rack shaft to amplify the steering force. The function of the braking system is to make the moving car slow down or even stop according to the driver's requirements, so that the stopped car can stop smoothly under various road conditions and keep the speed of the downhill car stable.
