Abstract

An energy recovery system for a vehicle comprises an arm mounted between a chassis of a vehicle and an axle of the vehicle. The arm is configured to pivot with respect to the chassis and the axle when the chassis is vertically displaced with respect to the axle. A one-way ratchet assembly couples the arm to an output shaft and is movable between an engaged position and a disengaged position. A torsion spring is coupled to the output shaft such that when the output shaft is rotated in a first direction, the torsion spring is tightened. An electromechanical assembly is configured to move the ratchet assembly from the engaged position to the disengaged position when the torsion spring reaches a pre-determined tightness, so that when the ratchet assembly is in the disengaged position, the torsion spring loosens and induces rotation of the output shaft in the second direction. A generator is coupled to the output shaft.
