The rear axle housing assembly comprises a rear upper axle housing body, a rear lower axle housing body, a rear left axle housing tube, a rear right axle housing tube and half-shaft casing flange plates. The rear upper axle housing body and the rear lower axle housing body are in a butt welding mode to form a rear axle housing body. The half-shaft casing flange plates are welded to the two ends of the formed rear axle housing body through the rear left and right axle housing tubes respectively. Reinforcing rings are arranged at the rear portion of the rear upper axle housing body and the rear portion of the rear lower axle housing body so as to connect the rear upper axle housing body with the rear lower axle housing body. The rear lower axle housing body is provided with an oil drain plug base. A left upper trailing arm support is arranged on the upper surface of the rear left axle housing tube. A left lower trailing arm support welding assembly is arranged on the lower surface of the rear left axle housing tube. A right upper trailing arm support is arranged on the upper surface of the rear right axle housing tube. A right lower trailing arm support welding assembly is arranged on the surface of the front side of the rear right axle housing tube.
