The invention relates to the field of driving systems, in particular to an electric driving system with a planetary gear train. The electric driving system with the planetary gear train comprises a driving motor and the planetary gear train driven by the driving motor, the planetary gear train comprises a power output shaft, a rotating shaft of the driving motor is a hollow rotating shaft, the power output shaft penetrates through the hollow rotating shaft, a first power output end is formed at one end of the power output shaft, and a second power output end is formed at the other end of the power output shaft. And the other end forms a second power output end. Due to the fact that the rotating shaft of the driving motor is the hollow rotating shaft, the power output shaft can penetrate through the driving motor to be arranged, the power output shaft extending towards the two sides is formed, and power output on the two sides is conducted at the same time through the first power output end and the second power output end at the two ends. The problem that in the prior art, an input shaft in an electric drive system is a solid shaft and is coaxially arranged with a power output shaft, so that an output shaft of the electric drive system can only face one side, and consequently the four-wheel drive structure of a vehicle is complex is solved.

    本发明涉及驱动系统领域,尤其涉及一种具有行星轮系的电驱动系统。具有行星轮系的电驱动系统,该电驱动系统包括驱动电机和被驱动电机驱动的行星轮系,行星轮系包括动力输出轴,所述驱动电机的转轴为空心转轴,动力输出轴贯穿空心转轴,且动力输出轴的一端形成第一动力输出端,另一端形成第二动力输出端。由于驱动电机的转轴为空心转轴,因此可以将该动力输出轴贯穿驱动电机进行布置,那么就形成了向两边进行延伸的动力输出轴,通过两端的第一动力输出端和第二动力输出端同时进行两侧的动力输出,进而解决了现有技术中电驱动系统中的输入轴为实心轴且和动力输出轴同轴布置使得电驱动系统的输出轴只能朝向一侧引起的车辆的四驱结构复杂的问题。
