Transmission system
The power generated by the passenger car engine is transmitted to the driving wheels by the drive train. The drive train has the functions of deceleration, shifting, reversing, power interruption, inter-wheel differential and inter-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.
Driving system
Accepts the power of the drive train, generates traction through the action of the driving wheels and the road, so that the car runs normally; bears the total weight of the car and the reaction force of the ground; relieves the impact of uneven roads on the body, attenuates the vibration of the car during driving, and maintains Ride comfort; cooperate with the steering system to ensure the steering stability of the car.
steering system
The special mechanism used on the passenger car to change or restore its driving direction is called the car steering system.
Braking System
A series of special devices on passenger cars that allow the outside world (mainly the road surface) to exert a certain force on certain parts of the car (mainly the wheels), so as to perform a certain degree of forced braking on it, collectively called the brake 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.
Chassis accessories
There are many accessories for passenger car chassis. In actual design, chassis accessories are usually designed by special personnel, which is conducive to the generalization of chassis design and the uniformity of layout.
