The invention provides a self-energized magneto-rheological shock absorber for a hub motor driven electric vehicle, and belongs to the field of vehicle system shock absorption. The self-energized magneto-rheological shock absorber is composed of a magneto-rheological shock absorber and a linear electromagnetic dynamic vibration absorber which are in rigid connection, is easy to control, small in energy consumption, and is used for restraining vehicle body vibration, and improving taking comfort of the hub motor driven electric vehicle; the linear electromagnetic dynamic vibration absorber comprises a stator and a rotor and always works in a passive energy feedback mode; the linear electromagnetic dynamic vibration absorber is a mass-rigidity-damping resonance system acting on wheels, doesnot need external control, so that vehicle body acceleration, tire dynamic load and suspension dynamic deflection in the resonance frequency band of the wheels are effectively reduced, vibration of the wheels is restrained, and driving safety of the hub motor driven electric vehicle is improved. When the stator and the rotor perform relative linear motion, a coil winding generates induction current to provide energy for the magneto-rheological shock absorber to realize self-energization of the shock absorber; and meanwhile, residual energy is stored in the storage battery to realize energy recovery.

    本发明提供了一种轮毂电机驱动电动汽车自供能磁流变减振器,属于车辆系统减振领域。本发明由刚性连接的磁流变减振器和直线电磁动力吸振器组成,控制简单、能耗较小的磁流变减振器用于抑制车身振动,提高轮毂电机驱动电动汽车乘坐舒适性;直线电磁动力吸振器包括定子和动子,且始终工作在被动馈能模式;直线电磁动力吸振器为作用于车轮的质量‑刚度‑阻尼共振系统,无需外部控制,有效降低车轮共振频段车身加速度、轮胎动载荷和悬架动挠度,抑制车轮的振动,提高轮毂电机驱动电动汽车行驶安全性。当定子与动子发生相对直线运动时,线圈绕组产生感应电流,为磁流变减振器提供能量,实现减振器自供能,同时,剩余能量储存至蓄电池,实现能量回收。
