The invention discloses an electric motor coach dual-power driving system and a torque distribution method, and relates to the technical field of pure electric motor coaches. The electric motor coachdual-power driving system comprises a first power battery, a first high-voltage power distribution cabinet, a first motor controller and a first motor which are connected in sequence, and further comprises a second power battery, a second high-voltage power distribution cabinet, a second motor controller and a second motor which are connected in sequence; the first motor and the second motor rotate coaxially and transmit driving force to a front axle or a rear axle through a transmission shaft. According to the invention, two sets of driving systems which operate independently are configured,the two motors in the driving systems rotate coaxially, and the torques are superposed to jointly drive the front axle or the rear axle, so that the phenomenon of single-motor overheating caused by continuous large-torque output can be avoided, the output balance of the two batteries can be ensured, the condition of single-battery overload is avoided, therefore, the service lives of the motor andthe batteries are effectively prolonged, and the stability and reliability of the driving system are improved.
本发明公开了一种电动客车双动力驱动系统及扭矩分配方法,涉及纯电动客车技术领域,该电动客车双动力驱动系统包括依次连接的第一动力电池、第一高压配电柜、第一电机控制器和第一电机,还包括依次连接的第二动力电池,第二高压配电柜、第二电机控制器和第二电机;所述第一电机和第二电机同轴旋转,并通过一传动轴传递驱动力至前桥或者后桥。本发明配置有两套独立运行的驱动系统,并且驱动系统中两电机同轴旋转,扭矩相互叠加,共同驱动前桥或者后桥,由此可避免持续性大扭矩输出而造成单电机过热的现象,并且可保证两电池输出平衡,避免出现单电池过负载的状况,从而有效延长电机和电池的使用寿命,提高了驱动系统的稳定性和可靠性。
