The invention belongs to the technical field of vehicle hybrid power systems, and provides a dual-motor two-gear power dividing driving system which is provided with a power generation motor and a driving motor, and a planetary power dividing mechanism is arranged between the power generation motor and an engine. The planetary power dividing mechanism transmits redundant part power of the engine to the power generation motor for power generation, the other part of power is coupled with power transmitted to the output shaft by the driving motor to drive a vehicle, double-motor hybrid power is achieved, the oil saving efficiency of the driving system is improved, and the pause feeling generated by power interruption of the driving motor in the gear shifting process can be reduced. Power source switching is realized by adopting a speed change device and a planetary power dividing mechanism; due to the fact that vehicle power can be provided by power coupling of the driving motor and the engine, the engine can be maintained in an efficient working area by changing the proportion of the power provided by the driving motor in total power.
本发明属于车辆混合动力系统技术领域,提供了一种双电机两挡功率分流驱动系统,驱动系统设有发电电机和驱动电机,发电电机和发动机之间设有行星功率分流机构。行星功率分流机构将发动机的冗余部分动力传递至发电电机用于发电,另一部分与驱动电机传递到输出轴上的动力耦合驱动车辆,实现双电机混动提高驱动系统的节油效率,并能够降低换挡过程中驱动电机动力中断产生的顿挫感;采用变速装置和行星功率分流机构,实现动力来源切换;由于车辆动力可以由驱动电机和发动机的动力耦合提供,可以通过改变驱动电机提供的动力在总动力中所占比例,使发动机维持在高效工作区。
