The invention discloses a novel rear axle housing which comprises an upper axle blank and a lower axle blank. The novel rear axle housing is characterized in that the upper axle blank and the lower axle blank are welded together, a semicircular groove is formed at the position between the upper axle blank and the lower axle blank, an axle shaft connection flange hole is formed, and the left end and the right end of the upper axle blank are each provided with a main reduction assembling hole. By means of the arrangement, the novel rear axle housing is drawn to be formed after integrally blanking, the tailored-welding process of a middle triangular plate is omitted, the gas leakage phenomenon caused by subsequent installation and welding is avoided, and the novel rear axle housing saves time and labor and is attractive in appearance. The novel rear axle housing is simple in structure and convenient to produce, reduces the production cost, and improves the production efficiency.
