The invention discloses an integrated speed reducer, a power system of an electric automobile and the electric automobile. The integrated speed reducer comprises a main shell, a driving motor, a planetary mechanism and a differential mechanism, the main shell extends in the first direction, a partition plate is arranged in the main shell, and a shaft hole is formed in the partition plate; the partition plate divides the main shell into a first inner cavity and a second inner cavity in the first direction, the driving motor is installed in the first inner cavity and comprises an output shaft, the planetary mechanism is installed in the second inner cavity and connected with the output shaft through a shaft hole, and the differential mechanism is installed in the second inner cavity and connected with the planetary mechanism. According to the technical scheme, the driving motor, the planetary mechanism and the differential mechanism are all installed in the main shell, only the partition plate is arranged between the driving motor and the planetary mechanism, the driving motor and the planetary mechanism are connected through the shaft hole, high integration of the speed reducer is achieved, the size of a transmission mechanism is reduced, materials are saved, and cost is reduced.

    本发明公开一种集成化减速器、电动汽车的动力系统以及电动汽车,所述集成化减速器包括:主壳体、驱动电机、行星机构以及差速器,主壳体沿第一方向延伸,主壳体内设有隔板,隔板开设有轴孔,隔板将所述主壳体沿第一方向分为第一内腔和第二内腔,驱动电机安装在所述第一内腔,驱动电机包括输出轴,行星机构安装在第二内腔,所述行星机构通过轴孔与所述输出轴连接,差速器安装在第二内腔,差速器与行星机构连接,本发明技术方案中驱动电机、行星机构以及差速器全部安装在主壳体内,仅在驱动电机和行星机构之间设置一隔板,通过轴孔相连,实现了减速器的高度集成化,缩小了传动机构的体积,节省材料降低成本。
