Hybrid vehicles drive system and drive method that use elasticity power and drive engine power

摘要

PURPOSE: A driving system of a hybrid vehicle is provided to reproduce the energy about to be consumed through braking frictional force to elastic energy. CONSTITUTION: A driving system of a hybrid vehicle comprises: a spring power shaft(110) being rotated by the brake friction generated by the brake of a vehicle from back wheels, which is formed to correspond to a vehicle power shaft(20); a pair of the sub power source(120), which is in the both side of the spring power shaft, facing each other; a screw(130) for storing elastic energy in the state of spring winded through the rotation of the spring power shaft; and a sub-power control part(140) for controlling the screw spring and supplying the sub power source accumulated during braking and supplying the power during accelerating.
