It connects the frame and wheels elastically and is related to the various performances of the car. From the outside, the suspension of a car is only composed of some rods, cylinders and springs, but don't think it is simple. On the contrary, the suspension of a car is a car assembly that is difficult to achieve perfect requirements. This is because the suspension must meet the requirements of both the comfort of the car and its handling stability, and these two aspects are mutually opposed. For example, in order to achieve good comfort, it is necessary to greatly buffer the vibration of the car, so the spring must be designed to be softer, but a soft spring can easily cause the car to "nod" when braking, "raise its head" when accelerating, and have a serious tendency to tilt left and right, which is not conducive to the steering of the car and easily leads to unstable handling of the car.
