The invention relates to the field of electric drive axles, and discloses an efficient single-motor gear shifting symmetrical electric drive axle which comprises a motor, an output shaft of the motor is fixedly connected with a first parallel shaft through a coupler, one end of the first parallel shaft is fixedly connected with a first-stage driving gear, and the outer wall of the first-stage driving gear is connected with a first-stage driven gear in a meshed mode. The invention discloses an efficient single-motor gear shifting symmetrical electric drive axle. A motor, a first parallel shaft, a first-stage driving gear, a first-stage driven gear, a second parallel shaft, a second-stage driving gear, a second-stage driven gear, a third parallel shaft, a second-gear driving gear, a first-gear driving gear, a first-gear combination gear, a first-gear and second-gear gear shaft, a second-gear combination gear, a spline gear hub, a gear shifter, a third-gear combination gear, a fourth-stage driven gear and a differential case are arranged. And the second-gear driven gear and the first-gear driven gear are symmetrically arranged, so that the NVH problem caused by the offset axle can be reduced, the structure of the electric drive axle is more stable, and the spatial arrangement is more reasonable.

    本发明涉及电驱桥领域,且公开了一种高效单电机换挡对称电驱桥,包括电机,所述电机的输出轴通过联轴器固定连接有第一平行轴,所述第一平行轴的一端固定连接有一级主动齿轮,所述一级主动齿轮的外壁啮合连接一级被动齿轮。该高效单电机换挡对称电驱桥,通过设置的电机、第一平行轴、一级主动齿轮、一级被动齿轮、第二平行轴、二级主动齿轮、二级被动齿轮、第三平行轴、二挡主动齿轮、一档主动齿轮、一档结合齿轮、一二档齿轮轴、二挡结合齿轮、花键齿毂、换挡器、三挡结合齿轮、四级被动齿轮、差速器壳、二挡从动齿轮和一档从动齿轮,对称式布置,能够减少偏置桥带来的NVH问题,使电驱桥结构更稳定、空间布置更合理。
