The invention relates to the technical field of electric automobiles, in particular to a coaxial planet row wheel edge electric drive system. The combination of the compound planetary gear reducer and the oil cooling motor is adopted, large reduction ratio and high volume power density can be achieved, and the left-right symmetrical design is adopted, so that modular design of parts is facilitated, and cost reduction is also facilitated. A double-electric-control integration scheme is adopted, and the problem of reliable connection of six UVW three-phase high-voltage lines and double-motor rotary transformer low-voltage lines is solved structurally, so that electric control modularization is realized, and the cost of the shell and the interface can be reduced. The two driving units adopt one oil cooling system, so that the system is simplified, and the cost is reduced. By the adoption of the wheel-side electric drive structure with the left motor and the right motor independently controlled, the torque of each wheel of an automobile with the wheel-side electric drive structure is independently controlled, the wheel-side electric drive structure is suitable for driving or braking working conditions, has the advantage of being large in system power torque reserve, and can meet the requirement for high-performance power of the whole automobile, and meanwhile a power system is safer and more energy-saving.

    本发明涉及电动汽车技术领域,具体涉及一种同轴行星排轮边电驱系统。采用复合行星齿轮减速器与油冷电机组合,能够实现较大的减速比,体积功率密度高,而采用左右对称设计,利于零件模块化设计,也利于降低成本。采用双电控集成方案,且结构上解决了UVW三相共6根高压线及双电机的旋变低压线的可靠连接的难点,既实现电控模块化,又能降低壳体和接口成本。两套驱动单元采用一套油冷系统,简化系统,降低成本。采用左右电机独立控制的轮边电驱结构,使具有其的汽车实现各轮扭矩独立控制,适用于驱动或制动工况,具有系统功率扭矩储备大的优势,能够在满足整车高性能动力需求的同时,使动力系统更安全更节能。
