The invention belongs to the technical field of vehicle electric drive, and particularly relates to a two-gear double-clutch coaxial electric drive axle. The two-gear double-clutch coaxial electric drive axle comprises a drive motor, three clutches, three planet rows and two output half shafts. Compared with the prior art, power switching of two speed ratio states can be achieved through mutual actuation control of the first clutch and the second clutch, motor design is quite friendly, coaxial high-compactness arrangement is achieved through preferable connection of the double-inner-meshing planet row, the light differential mechanism and the like, the number of parts is reduced, the weight of the parts is reduced, and cost is reduced. And the manufacturing cost is reduced.

    本发明属于车辆电驱动技术领域,具体涉及一种两挡双离合同轴电驱动桥。所述两挡双离合同轴电驱动桥包括:驱动电机、三个离合器、三个行星排、两个输出半轴;与现有技术相比较,本发明利用第一离合器和第二离合器的互位作动控制,可实现两种速比状态的动力切换并对电机设计十分友好,利用双内啮合行星排、轻型差速器等的优选连接,实现了同轴高紧凑布置,减轻了零件数和重量,降低了制造成本。
