Technical Problem
[0002]现有技术的电驱动总成中，通常通过螺旋伞齿轮作为主齿轮进行减速传动，以确保稳定的传动比并且具有较低的噪音，目前的电驱动总成中通常将驱动电机、行星轮减速器、主齿轮、差速器沿电机转子轴的轴线依次排列，使得电驱动总成的轴向尺寸较长，导致电驱动总成车内的空间占比较大
Benefits of technology
[0017]本申请提供的电驱动总成，通过电机模块的转子轴提供动力，行星模块与转子轴传动连接，对电机模块的传输动力进行一级减速，并通过锁紧螺栓将行星模块与主动齿轮转动连接，在主动齿轮的齿轮轴内部开设有供锁紧螺栓连接的连接孔，且转子轴与行星模块传动连接的一端开设有避让槽用于容置锁紧螺栓，缩短了行星模块沿转子轴轴向分布的尺寸，使得转子轴、行星模块以及主动齿轮依次紧密分布，之后通过被动齿轮传动连接差速器模块，使得电机模块、行星模块、主动齿轮、差速器模块沿转子轴的轴向依次分布，缩短了电驱动总成的轴向尺寸，降低了电驱动总成的空间占比。
