The two-gear electric drive axle system comprises a first motor and a second motor; the first driving gear is connected with the first motor; the second driving gear is connected with the second motor; the first intermediate shaft is fixedly connected with a driven gear, a first planet row and an intermediate shaft combination gear in sequence; the second intermediate shaft and the first intermediate shaft are coaxially arranged, the second intermediate shaft is sequentially and fixedly connected with a synchronous gear sleeve and a second planet row, and the synchronous gear sleeve can be switched among a first position, an intermediate position and a second position; the differential mechanism is connected with a first output half shaft and a second output half shaft and is connected with a planet carrier of the second planet row; the first hub reduction mechanism is respectively connected with the first output half shaft and a first wheel; and the second hub reduction mechanism is respectively connected with the second output half shaft and a second wheel. The two combination teeth are located on the same side of the synchronous gear sleeve, and three-gear switching is achieved. The fixed shaft gear and the double planet rows are connected in series for transmission, and the functions of large reduction ratio and large torque transmission can be achieved.

    提供了一种两挡电驱动桥系统,包括:第一电机和第二电机;第一主动齿轮,与第一电机连接;第二主动齿轮,与第二电机连接;第一中间轴,依次固定连接有被动齿轮、第一行星排和中间轴结合齿;第二中间轴,与第一中间轴共轴布置,且依次固定连接有同步齿套和第二行星排,该同步齿套可在第一位置、中间位置和第二位置之间切换;差速器,连接有第一输出半轴和第二输出半轴,且与第二行星排的行星架连接;第一轮边减速机构,分别与第一输出半轴和第一车轮连接;以及第二轮边减速机构,分别与第二输出半轴和第二车轮连接。两结合齿位于同步齿套同一侧布置,实现三挡位切换;定轴齿轮加双行星排串联传动,可以实现大减速比,传递大扭矩的功能。
