The invention belongs to the automobile conservation technology and the novel suspension field, and in particular relates to an automobile suspension vibration energy regeneration system. The novel energy reclaiming suspension system comprises a lower-mobility parallel mechanism, a rotary ultrasonic motor, a super capacitor and a storage battery. The novel energy reclaiming suspension system can convert vertical vibration of the automobile suspension into rotary movement of the rotary ultrasonic motor by the lower-mobility parallel mechanism, and the rotary movement makes the surface of a piezoelectric disk of the ultrasonic motor be deformed under the action of the friction to generate electrical energy. The system has simple structure, high rigidity, high sensitivity and high energy conversion efficiency, and can effectively achieve the suspension vibration energy recovery.
