The invention discloses a two-gear coaxial dual-motor composite electric driving device, which belongs to the technical field of vehicle electric driving and is characterized in that a rotor shaft of a first driving motor, a rotor shaft of a second driving motor, a first output half shaft and a second output half shaft are coaxial; the first driving motor and the second driving motor are coupled through the planet row transmission mechanism to drive the first output half shaft and the second output half shaft to rotate so as to achieve power equalization of the first output half shaft and the second output half shaft when the vehicle runs straight, and power flows back from the output shaft on the low-speed side to the output half shaft on the high-speed side when the vehicle turns. Mechanical transmission recycling of steering regeneration power is achieved in dynamics, the requirement for motor power is lowered, the whole two-gear coaxial dual-motor composite electric driving device is simple and compact in structure, the vehicle size constraint condition is met, the straight driving stability and steering flexibility are improved, and application of series-connection type pure electric driving to a high-power vehicle is promoted.

    本发明公开了一种两挡同轴双电机复合电驱动装置,属于车辆电驱动技术领域,第一驱动电机的转子轴、第二驱动电机的转子轴、第一输出半轴、第二输出半轴同轴;第一驱动电机与第二驱动电机通过行星排传动机构耦合驱动第一输出半轴与第二输出半轴转动,用于实现车辆直驶时第一输出半轴与第二输出半轴的功率均分,车辆转向时功率从低速侧的输出轴向高速侧的输出半轴功率回流。在动力学上实现了转向再生功率的机械传动回收利用,降低了对电机功率的需求,整个两挡同轴双电机复合电驱动装置结构简单紧凑,满足车辆尺寸约束条件,提高了直驶稳定性和转向灵活性,促进串联式纯电驱动在大功率车辆上的应用。
