The invention relates to an electric drive axle system which comprises a differential mechanism, a first planet carrier, a first drive part, a second drive part and at least two hub reduction assemblies, the first planet carrier is fixedly connected with the power input end of the differential mechanism, and the first drive part is in transmission connection with a first rotating shaft through a first primary gear reduction part; the second driving part is in transmission connection with the power input end of the differential mechanism through the second primary gear speed reducing part; according to the electric drive axle system, the hub speed reduction assembly is arranged at the power output end of the differential mechanism, the torque transmission stability is improved, the second drive piece can continuously provide power during gear shifting, it is guaranteed that the differential mechanism can always guarantee power output in the gear shifting process, the car sliding risk in the gear shifting process is reduced, and the service life of the electric drive axle system is prolonged. In addition, the electric drive axle system can meet the speed reduction transmission requirement only by using the first-stage gear speed reduction part, the number of speed reduction gears is effectively reduced, the integration degree of the electric drive axle is improved, and the production cost is reduced.

    本申请涉及一种电驱动桥系统,包括差速器、第一行星架、第一驱动件、第二驱动件和至少两个轮边减速组件,第一行星架与差速器的动力输入端固定连接,第一驱动件通过第一一级齿轮减速件与第一旋转轴传动连接,第二驱动件通过第二一级齿轮减速件与差速器的动力输入端传动连接;本申请的电驱动桥系统,通过在差速器动力输出端设置轮边减速组件,增加扭矩传递的稳定性,使第二驱动件在换挡时可不间断提供动力,保证在换挡过程中差速器始终能够保证动力输出,减少了换挡过程中的溜车风险,且本申请的电驱动桥系统仅使用一级齿轮减速件即可满足减速传动需求,有效减少减速齿轮数量,提高了电驱动桥的集成度并降低了生产成本。
