The invention relates to the technical field of electric drive axles, and discloses a highly-integrated integrated electric drive axle system which comprises an integrated shell, a motor shaft and rotor sub-assembly is arranged in the integrated shell, a stator sub-assembly is arranged at one side of the motor shaft and rotor sub-assembly, a water channel is formed in one side of the stator sub-assembly, one side of the stator sub-assembly and one side of the water channel are fixedly connected with the same motor end cover, a differential shaft sub-assembly is arranged on the inner wall of the integrated shell, and an axle housing sub-assembly is arranged on one side of the differential shaft sub-assembly. A driving motor, a speed reducer and a differential mechanism are integrated into a whole to form the highly-integrated integrated electric drive axle assembly, the comprehensive weight reduction effect is good, errors caused by separated machining and assembly errors of the motor and the speed reduction box are avoided, transmission errors of gears are reduced, NVH of a driving system is optimized, the cost is reduced, and the enterprise revenue is improved.

    本发明涉及电驱动桥技术领域,且公开了一种高度集成的一体化电驱动桥系统,包括一体化壳体,所述一体化壳体的内部设有电机轴及转子分总成,电机轴及转子分总成的一侧设有定子分总成,定子分总成的一侧设有水道,所述定子分总成和水道的一侧固定连接有同一个电机端盖,所述一体化壳体的内壁上设有差速器轴分总成,且差速器轴分总成的一侧设有桥壳分总成。本发明将驱动电机、减速器及差速器都集成为一体,组成一个高度集成的一体化电驱动桥总成,综合减重效果好,避免了由于分开式加工带来的误差及电机与减速箱的装配误差,降低了齿轮的传递误差,优化了驱动系统的NVH,降低成本,提高企业效益。
