At present, the automobile suspension is a device that elastically connects the frame and the axle in the automobile. It is generally composed of shock-absorbing springs, guide mechanisms, shock absorbers and other components, and its main task is to ease the impact transmitted from the uneven road to the frame to improve the comfort of the car.

When passing through an uneven road surface, the shock-absorbing spring is used to filter the vibration of the road surface, but the shock-absorbing spring itself will have reciprocating motion, and the shock absorber installed in parallel with the shock-absorbing spring is mainly used to suppress the shock when the spring rebounds after absorbing shock and the shock from the road surface. shock. In order to attenuate the vibration, the shock absorber used in the automobile suspension system is mostly a hydraulic piston shock absorber. Its working principle is that when there is relative movement between the frame (or body) and the axle, the piston in the shock absorber Moving up and down, the oil in the shock absorber cavity will repeatedly flow from one cavity through different pores into another cavity.

Under normal circumstances, these vibration energies cannot be converted or stored in time and are wasted. With the popularization of automobile use, more and more energy is wasted.

The suspension system currently on the market still stays on the simple buffering and shock absorption function, and does not provide a good technical solution for converting mechanical energy into other energy.
