The invention discloses an electrically driven power transmission device which comprises a shell, a drive motor, a planet row gear mechanism, a first friction operation device and a second friction operation device, the planet row gear mechanism comprises a first sun gear, a second sun gear, a planet carrier, a first planet gear and a second planet gear, and the first planet gear and the second planet gear are arranged on the planet carrier. The first planetary gear is meshed with the first sun gear, the second planetary gear is meshed with the second sun gear, and the first friction running device is arranged to be used for braking the first sun gear; the second friction operation device is arranged to be used for controlling the first sun gear and the second sun gear to rotate synchronously so that the whole planet row gear mechanism can rotate. According to the electrically-driven power transmission device, power output can be kept through mutual cooperation of the two friction operation devices in the gear shifting process, and power interruption in the gear shifting process is avoided; and a planetary mechanism composed of the cylindrical outer gears is adopted, machining and manufacturing are convenient, and the product development difficulty is lowered.

    本发明公开了一种电驱动动力传动装置,包括壳体、驱动电机、行星排齿轮机构、第一摩擦运行装置和第二摩擦运行装置,行星排齿轮机构包括第一太阳轮、第二太阳轮、行星架以及设置于行星架上的第一行星齿轮和第二行星齿轮,第一行星齿轮与第一太阳轮相啮合,第二行星齿轮与第二太阳轮相啮合,第一摩擦运行装置被设置成用于制动第一太阳轮;第二摩擦运行装置被设置成用于控制第一太阳轮和第二太阳轮同步旋转,以使行星排齿轮机构整体转动。本发明的电驱动动力传动装置,可以在换挡过程中通过两个摩擦运行装置相互配合,保持动力输出,避免了换挡过程的动力中断;而且采用由圆柱外齿轮构成的行星式机构,便于加工制造,降低产品开发难度。
