The invention provides a dual-motor electric drive axle assembly with a hub reduction gear. The dual-motor electric drive axle assembly comprises a first drive motor M1 and a second drive motor M2 which are distributed on the two sides of an axle. The first driving motor M1, the first gear transmission speed reduction module, the second gear transmission speed reduction module and the third gear transmission speed reduction module are connected in sequence, and the power output of the first driving motor M1 transmits power to the third gear transmission speed reduction module through the first gear transmission speed reduction module and the second gear transmission speed reduction module in sequence; and the power output of the second driving motor M2 transmits the power to the third gear transmission speed reduction module through the fourth gear transmission speed reduction module and the fifth gear transmission speed reduction module in sequence to be converged with the power of the first driving motor M1. Driving force is coupled differently at different vehicle speeds and under different loads, real-time power distribution is achieved, and the power performance of the whole vehicle is improved; single-motor driving is achieved under common working conditions, the motor load rate is increased, and the whole vehicle economy is improved.

    本发明提供一种带轮边减速器双电机电驱动桥总成,包括:分布在车桥两侧的第一驱动电机M1和第二驱动电机M2;第一驱动电机M1、第一齿轮传动减速模块、第二齿轮传动减速模块以及第三齿轮传动减速模块依次连接,第一驱动电机M1动力输出依次通过第一齿轮传动减速模块、第二齿轮传动减速模块将动力传递到第三齿轮传动减速模块;第二驱动电机M2动力输出依次通过第四齿轮传动减速模块、第五齿轮传动减速模块将动力传递到第三齿轮传动减速模块,与第一驱动电机M1动力汇合。本发明在不同车速、不同负载下的驱动力不同耦合,实现动力实时分配,提高整车动力性;普通工况单电机驱动,提高电机负载率,提升整车经济性。
