The invention discloses a driving system for a pure electric vehicle, which comprises a pure electric power system consisting of a front wheel single motor and a rear wheel two-hub motor, the system mainly comprises a main motor, a left rear wheel hub motor with a clutch, a right rear wheel hub motor with a clutch, a main clutch, a differential mechanism, a main control inversion all-in-one machine, a power battery and a battery management system, a whole vehicle controller comprises a three-clutch mode switching system, an electronic controller and the like, and the three motors are permanent magnet synchronous motors; the electromagnetic resistance and the mechanical resistance of the permanent magnet synchronous motor which does not work are cut off through the on-off of the clutch, so that the working efficiency of the motor is greatly improved, the power consumption is reduced, and the driving range is increased. Meanwhile, the hub motor with the clutch can provide torque to maintain the stability of a vehicle body in the slipping or swinging process of the vehicle, and the driving safety and comfort are improved.

    本发明公开了一种所述用于纯电动汽车的驱动系统,其中包括一种前轮单电机和后轮两轮毂电机组成的纯电动动力系统,主要包括主电机、左后轮带离合轮毂电机、右后轮带离合轮毂电机、主离合器、差速器、主控制逆变一体机、动力电池与电池管理系统、整车控制器包括三离合模式切换系统、电子控制器等,其中三部电机均为永磁同步电机;过离合器的通断切断了不工作永磁同步电机的电磁阻力和机械阻力,大大提高了电机的工作效率,减少了电耗,增加了续驶里程。同时,带离合轮毂电机的设置能够在车辆打滑或摆动的过程中提供力矩维持车身稳定,提高了驾驶的安全性和舒适性。
