The invention discloses an electric drive axle assembly for a vehicle, and relates to the technical field of vehicles, the electric drive axle assembly comprises a middle axle electric drive axle assembly and a rear axle electric drive axle assembly, the middle axle electric drive axle assembly comprises a middle axle shell section speed reduction assembly, and the rear axle electric drive axle assembly comprises a rear axle shell section speed reduction assembly. The middle axle electric drive axle assembly and the rear axle electric drive axle assembly further comprise electric drive main speed reducer assemblies, and the electric drive main speed reducer assemblies comprise any one of the first electric drive main speed reducer assembly, the second electric drive main speed reducer assembly and the third electric drive main speed reducer assembly. According to the electric drive axle assembly, multi-stage and multi-gear speed change can be achieved, the output of the middle axle electric drive axle assembly and the output of the rear axle electric drive axle assembly can meet power of various working conditions, and the effects of large torque and large rotating speed are provided for a vehicle when the vehicle needs large power during starting, accelerating and climbing and the vehicle provides large rotating speed during high-speed running are achieved; therefore, the performance index of the whole vehicle is improved, and the use cost of the whole vehicle is reduced.

    本发明公开了一种用于车辆的电驱动桥总成,涉及车辆技术领域,包括中桥电驱桥总成和后桥电驱桥总成,中桥电驱桥总成包括中桥壳段减速总成,后桥电驱桥总成包括后桥壳段减速总成,中桥电驱桥总成和后桥电驱桥总成还包括电驱动主减速器总成,电驱动主减速器总成包括第一电驱动主减速器总成、第二电驱动主减速器总成和第三电驱动主减速器总成中的任意一种。本发明提供的电驱动桥总成能实现多级多档变速,使中桥电驱桥总成和后桥电驱桥总成的输出可以满足多种工况的动力,在车辆处于启动、加速、爬坡需要大动力和车辆高速行驶时提供大转速时分别为车辆提供大扭矩和大转速的效果,从而有助于提升整车的性能指标,降低整车使用成本。
