Energy regeneration device of suspension system for vehicle

An energy regeneration device of a suspension system for a vehicle, the device comprising:

• a suspension link that connects a wheel carrier to a vehicle body;
• a bush unit that is disposed between a vehicle body connection portion of the suspension link and the vehicle body and outputs hinge motion of the suspension link through an output gear;
• a one-way power transmission mechanism that is connected with the output gear of the bush unit, receives the hinge motion transmitted from the output gear through an input gear, and outputs only one-way rotational power;
• a generator that is disposed at a side of the vehicle body and generates electricity while being rotated by the transmitted one-way rotational power;
• a speed-up mechanism that is disposed between the generator and the one-way power transmission mechanism, speeds up one-way rotational power transmitted from the one-way power transmission mechanism, and transmits the one-way rotational power increased in speeds to a rotary shaft of the generator;
• a rectifier that is electrically connected with the generator and rectifies the electricity generated by the generator;
• and
• a battery that is electrically connected with the rectifier and accumulates electric energy.
