Main types of suspension and their functions

Suspension is an important part of the car. Its main function is to transfer various forces such as supporting force, driving force, braking force and lateral reaction force to the frame or load-bearing body to ensure the stable driving of the car. The types of suspension include longitudinal leaf spring non-independent suspension, McPherson independent suspension, multi-link independent suspension, double wishbone front independent suspension and double wishbone rear independent suspension and air adjustable suspension. Each type of suspension has its specific functions and advantages. For example, multi-link independent suspension can achieve the best position of the kingpin caster angle, greatly reduce the force from the front and rear directions of the road surface, improve the driving smoothness and comfort, and ensure the stability of straight-line driving. The air adjustable suspension can automatically adjust the height of the chassis according to the speed and load of the vehicle, improving the stability when driving at high speed or the passability in complex road conditions.
