The invention provides a double-motor electric drive axle and a vehicle and a machine comprising the electric drive axle. The double-motor electric drive axle comprises a main drive motor assembly, an auxiliary drive motor assembly and an axle transmission assembly. Wherein the main driving motor assembly is connected with the axle transmission assembly and provides driving force for the axle transmission assembly or reverse charging of the power battery is achieved through the axle transmission assembly; the auxiliary driving motor assembly is configured to be controllably connected with the axle transmission assembly through the joint assembly, and provides driving force for the axle transmission assembly or achieves reverse charging of the power battery through the axle transmission assembly during connection according to requirements. According to the double-motor electric drive axle, the main motor and the auxiliary motor can work simultaneously or independently, the best loading and climbing performance is achieved, mechanical loss is reduced, and meanwhile the problem that power of the drive axle is not interrupted is solved. During operation, the motor always operates in an economical power consumption area, and the best power consumption economy can be achieved.

    本发明提供了一种双电机电驱动桥及包括该电驱动桥的车辆和机械。所述双电机电驱动桥包括主驱动电机组件、辅助驱动电机组件和车桥传动总成;其中,主驱动电机组件与车桥传动总成连接,为车桥传动总成提供驱动力或通过车桥传动总成实现为动力电池的反充电;辅助驱动电机组件构造成通过接合组件与车桥传动总成可控连接,根据需求在连接时为车桥传动总成提供驱动力或通过车桥传动总成实现为动力电池的反充电。本发明的双电机电驱动桥能够主、副双电机同时或单独工作,实现最好的载重和爬坡性能,降低机械损耗,同时解决驱动桥动力不中断的难题。运行时电机一直在经济电耗区运转,可以实现最好的电耗经济性。
