ENERGY REGENERATION DEVICE OF SUSPENSION SYSTEM FOR VEHICLE

摘要

Disclosed is an energy regeneration device of a vehicle suspension. The disclosed energy regeneration device of a vehicle suspension includes i) a suspension link connecting a wheel carrier with a vehicle body and in which bumps and rebounds continuously occur in accordance with a road condition; ii) a bush unit installed between a connection portion at the vehicle body side of the suspension link and the vehicle body, to output two-way rotary power of the vehicle-body-side connection portion generated by vertical hinge motion of the suspension link, to an output gear; iii) a one-way power transferring means connected to the output gear of the bush unit to receive the two-way rotary motion transferred from the output gear to an input gear to output only the one-way rotary power to a multiplying gear; iv) a generator installed at one side of the vehicle body to generate electrical energy while being rotated by the transferred one-way rotary power; v) a gearbox disposed between the generator and the one-way power transferring means to accelerate the one-way rotary power transferred from the one-way power transferring means and transfer the one-way rotary power to a rotary shaft of the generator; vi) a rectifier electrically connected with the generator to rectify generated electricity; vii) and a battery electrically connected with the rectifier to store the electrical energy, wherein the bush unit may include an elastic member transferring the rotary power to the generator by absorbing external force and torsional force inputted by the vehicle-body-side connection portion.
