Distributed drive motor axle for heavy commercial vehicles

The invention provides a distributed driving motor axle for a heavy commercial vehicle, and relates to the technical field of power systems. The axle comprises a power assembly, an axle housing, a hub reduction gear and a hub assembly. The two power assemblies are installed on the axle housing through supporting structures and are symmetrical about the front and back of the axle housing. The output end of any power assembly is connected with the corresponding hub reduction gear, so that power is transmitted to the corresponding hub assembly. A power assembly of the whole vehicle is integrated on the axle, so that the arrangement space of the whole vehicle is released, and the weight and the gravity center of the whole vehicle are reduced; the gravity center of the whole bridge is on the central axis of the bridge, the structural reliability is high, and low-frequency impact caused by eccentricity of the gravity center of the whole bridge is effectively reduced; according to the mounting structure, decoupling
