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.
