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.
