The invention relates to the technical field of vehicle power assemblies, in particular to an electric drive axle, a power assembly and an electric vehicle. The electric drive axle comprises a motor, a first planet row and a second planet row, an output shaft of the motor is connected with a sun gear of the first planet row, a gear ring of the first planet row is connected with an axle housing, a planet carrier of the first planet row is connected with a sun gear of the second planet row, a gear ring of the second planet row is connected with the axle housing, and a planet carrier of the second planet row is connected with a driving shaft; the motor, the first planet row and the second planet row are coaxially arranged on the driving shaft in a sleeving mode. According to the electric drive axle, through the arrangement mode that the motor, the first planet row and the second planet row are coaxially arranged on the drive shaft in the sleeving mode, it can be guaranteed that the cross section of the axle shell can be close to a circle, and no other radial protrusions exist, so that the trafficability of a chassis is remarkably improved, and arrangement work of other parts located around the electric drive axle is more convenient.
本公开涉及车辆动力总成技术领域,尤其涉及一种电驱动桥、动力总成以及电动汽车。该电驱动桥包括:电机、第一行星排和第二行星排;所述电机的输出轴与所述第一行星排的太阳轮连接,所述第一行星排的齿圈与桥壳连接,所述第一行星排的行星架与所述第二行星排的太阳轮连接,所述第二行星排的齿圈与桥壳连接,所述第二行星排的行星架与驱动轴连接;所述电机、所述第一行星排和所述第二行星排均同轴套设在所述驱动轴上。该电驱动桥,通过将电机、第一行星排和第二行星排同轴套设在驱动轴上的设置方式,可以保证桥壳的截面可以接近圆形,不会有其他径向上的凸起,从而显著地提高了底盘的通过性,以及更加方便位于电驱动桥周围的其他零件的布置工作。
