The invention belongs to the technical field of electric drive bridges, and discloses a coaxial three-gear double-motor electric drive bridge structure. The motor comprises a first motor body and a second motor body, a first cavity is formed in the first motor body, a second cavity is formed in the second motor body, the first motor body and the second motor body are coaxially and adjacently installed on an axle of a vehicle, a first planetary gear set is installed in the first cavity, and a third planetary gear set is installed in the second cavity. The problem that in the prior art, when an electric drive axle structure achieves three-gear adjustment, the occupied size of the axial space of a transmission shaft is large is solved.

    本发明属于电驱桥技术领域,公开了一种同轴式三挡双电机电驱桥结构。其中包括第一电机和第二电机,第一电机内形成有第一腔体,第二电机内形成有第二腔体,第一电机和第二电机同轴并相邻安装在车辆的桥上,第一腔体内安装有第一行星齿轮组,第二腔体内安装有第三行星齿轮组;解决现有技术下电驱桥结构实现三挡调节的时候在传动轴轴向空间占用体积较大的问题。
