Distributed driving motor axle for heavy commercial vehicle

The invention belongs to the technical field of motor axles, and discloses a distributed driving motor axle for a heavy commercial vehicle, which comprises an assembling axle housing, a left power assembly and a right power assembly are mounted in the assembling axle housing, and the two power assemblies are mounted in the assembling axle housing through four supporting structures; the opposite faces of the two power assemblies are connected with hub reducers through output shafts. The power assemblies are installed on the assembling axle housing through the supporting structures, the two power assemblies are symmetrically installed on the front side and the rear side of the assembling axle housing correspondingly, the gravity center of the whole axle is located on the central axis of the axle, the structural reliability is high, and low-frequency impact caused by eccentricity of the gravity center of the whole axle is effectively reduced; meanwhile, decoupling of bearing and transmission is achieved through
