The invention belongs to the technical field of electric drive assemblies, and particularly provides an electric drive assembly for an electric vehicle and the electric vehicle. According to the electric drive assembly, the electric drive assembly is composed of an input shaft integrated with a motor rotor and a gear box first-stage driving gear, three intermediate shafts integrated with gear box first-stage driven gears and a second-stage driving gear, and a differential integrated with a second-stage driven gear. The three intermediate shafts are uniformly arranged around the input shaft. The power of the motor is divided into three paths from the first-stage driving gear through three intermediate shafts and is transmitted to the second-stage driven gear on the differential mechanism. The structure is small in size, light in weight and large in load transmission capacity, the problem that a planetary gear ring adopted by a traditional coaxial electric drive assembly structure is poor in manufacturing precision is solved, and the NVH performance is better.

    本发明属于电驱动总成技术领域,具体提供一种用于电动车辆的电驱动总成及一种电动车辆。本发明提供了一种电驱动总成,该电驱动总成由一根集成有电机转子及齿轮箱一级主动齿轮的输入轴、三根集成有齿轮箱一级从动齿轮及二级主动齿轮的中间轴、一个集成有二级从动齿轮的差速器组成。三个中间轴均匀布置在输入轴周围。电机的动力从一级主动齿轮处经三根中间轴均分三路传递至差速器上的二级从动齿轮。该结构体积小、重量轻、传递载荷的能力大,回避了传统同轴电驱动总成结构所采用的行星齿轮齿圈的制造精度差的问题,在NVH性能上更优。
