Automobile energy renewable vibration absorber

The invention discloses an automobile energy renewable vibration absorber, comprising an upper working cylinder and a lower working cylinder, wherein the lower working cylinder is connected into the upper working cylinder in a sliding mode; a energy renewable motor and a transmission mechanism are arranged in the upper working cylinder; and a motion transformation mechanism is arranged in the lower working cylinder. The motion transformation mechanism is a ball screw rod pair, transfers linear motion caused by the vibration of automobile wheels to rotary motion and transfers up and down motion to unidirectional rotary motion through overrunning clutchs with mutual opposite clutch directions in the transmission mechanism, and energy is transferred to electric power for use by the energy renewable motor.
