Abstract:
1. An energy renewal device provided in a hybrid or electric vehicle having wheels, the energy renewal device comprising: shock absorbers (A) provided for each separate one of the wheels; an accumulator (B); a hydraulic motor (D); a generator (E); an oil tank (C); a converter (O); and a battery (P), the shock absorbers (A) each including an oil suction valve port (A while the vehicle is traveling, extension and contraction of the shock absorbers (A) causing the shock absorbers (A) provided for each separate one of the wheels to act as oil pumps, the shock absorbers (A) performing two functions, namely (i) a function of acting as oil pumps and (ii) a function of bringing about a damping effect, during the contraction of the shock absorbers (A) and during the extension of the shock absorbers (A), respectively, such that during the contraction of the shock absorbers (A), each of the shock absorbers (A) pressure-feeds oil into the accumulator B through the oil discharge valve port (A the oil pressure-fed from the shock absorbers (A) being accumulated in the accumulator (B) and having its pressure raised, the oil pressure thus raised driving the hydraulic motor (D), electricity being produced by the generator (E) coupled to the hydraulic motor (D) and being transmitted to the battery (P) so that the hybrid or electric vehicle is charged with auxiliary electric power.
