Usually including suspension arms, suspension springs, suspension shock absorbers, suspension brackets, suspension bearings, suspension controllers, and other components. Usually includes three types of components:
(1) The connecting rod between the wheel and the frame controls the way and angle of wheel movement. The commonly heard types of connecting rods include double arm, single arm, and multi link.
(2) The spring located between the connecting rod and the frame is used to support the weight of the vehicle and also provides cushioning when the wheels pass through uneven obstacles. There are many types of springs, including spiral, steel plate, torque rod, and even a rubber or an air filled capsule.
(3) The function of a shock absorber is to reduce oscillations. In addition to stabilizing the vehicle, it is more important to ensure good contact between the wheels and the ground.
