Its function is to transmit the force and torque between the wheel and the frame, buffer the impact force transmitted from the uneven road to the frame or body, and attenuate the vibration caused by it, so as to ensure that the vehicle can run smoothly. The typical suspension system structure is composed of elastic elements, guide mechanism and shock absorber. Some structures also have buffer blocks, transverse stabilizer bars and so on. The elastic elements include leaf spring, air spring, coil spring and torsion bar spring. The suspension system of modern cars mostly adopts coil spring and torsion bar spring, and some high-end cars use air spring. Suspension system is an important assembly in the automobile. It connects the frame and wheels elastically, which is related to the various performance of the automobile. From the appearance, the car suspension system is only composed of some rods, cylinders and springs, but don't think it's very simple. On the contrary, the car suspension is a car assembly that is difficult to meet the perfect requirements, because the suspension system should not only meet the comfort requirements of the car, but also meet the requirements of its handling and stability, and these two aspects are opposite to each other. For example, in order to achieve good comfort, the vibration of the car needs to be greatly buffered, so the spring should be designed softer, but if the spring is soft, it is easy to make the car have serious adverse tendencies of braking "nodding", accelerating "looking up" and left and right roll, which is not conducive to the direction of the car and easy to lead to unstable operation of the car.
