The invention provides an integrated double-motor distributed drive electric drive axle. The drive axle comprises an integrated power assembly, an axle housing and a hub reduction system, the integrated power assemblies are respectively arranged at the front end and the rear end of the axle housing; the integrated power assembly comprises a driving motor, a speed reducer and a differential mechanism; the driving motor drives the speed reducer and the differential; the hub reducers are respectively arranged at the left and right ends of the axle housing; the hub reduction gear arranged at the left end of the axle housing is in transmission connection with the differential mechanism of the integrated power assembly arranged at the rear end of the axle housing through a first half shaft; thehub reduction gear arranged at the right end of the axle housing is in transmission connection with the differential mechanism of the integrated power assembly arranged at the front end of the axle housing through the second half shaft, and therefore the integrated power assembly has the advantages that the weight of the assembly is reduced, the overall efficiency of the axle is improved, and meanwhile the space utilization rate of the whole vehicle is increased.

    本发明提出了一种集成式双电机分布式驱动电驱动桥,包括集成式动力总成、桥壳和轮边减速系统,集成式动力总成分别设置于桥壳的前端和后端,集成式动力总成包括驱动电机、减速器和差速器,驱动电机用于驱动减速器和差速器,轮边减速器分别设置于桥壳的左右两端,置于桥壳左端的轮边减速器和置于桥壳后端集成式动力总成的差速器之间通过第一半轴传动连接,置于桥壳右端的轮边减速器和置于桥壳前端集成式动力总成的差速器之间通过第二半轴传动连接,借此,本发明具有降低了总成重量,提高了车桥整体的效率,同时也提高了整车的空间利用率的优点。
