Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of commercial vehicle electric drive axles, in particular to an integrated dual-motor distributed drive electric drive axle. Background technique

[0002] In recent years, with the continuous development of the new energy vehicle industry, major car companies and end users have paid more and more attention to the power system of new energy vehicles, especially the structural form of the power system and the spatial layout of the vehicle. At present, domestic and foreign products mostly adopt the direct drive form of the drive motor and the traditional axle. The power is generated by the drive motor, and the power is transmitted to the traditional drive axle through the reduction box or gearbox through the transmission shaft to realize the drive of the whole vehicle. On the other hand, the axle adopts simple integration with the motor, mostly connecting the drive motor with the axle through bolts. For the fi...
