The invention provides a rear axle housing assembly of a dumper and the dumper. The rear axle housing assembly of the dumper comprises a rear axle housing; longitudinal rib plates which are arranged on the inner wall of the rear axle shell at intervals in the circumferential direction; transverse rib plates which are connected with two adjacent longitudinal rib plates, and one end faces of the longitudinal rib plates, one end face of each transverse rib plate and one end face of the rear axle shell are flush with one another and form a supporting face; and a flange which is installed on the end face of the rear axle shell and a supporting face formed by the longitudinal rib plates and the transverse rib plates. In the rear axle housing assembly, the flange can be supported by the longitudinal rib plates and the transverse rib plates besides being supported by the rear axle shell, so that the mounting contact area of the flange is increased, the reliability of the connection between the flange and the longitudinal rib plates and the transverse rib plates is ensured, and the defect that the flange cannot be connected with the longitudinal rib plates and the transverse rib plates, and only the flange can be supported through the rear axle shell, so that the supporting surface is insufficient in prior art is overcome.
本发明提供了一种自卸车后桥壳总成和自卸车,自卸车后桥壳体总成包括:后桥壳体;多个纵向筋板,沿周向方向间隔设置在后桥壳体的内壁上;横向筋板,连接多个纵向筋板中相邻的两个,且多个纵向筋板的一端面、横向筋板的一端面、后桥壳体的一端面相互平齐并形成一支撑面;法兰,安装在后桥壳体的端面、多个纵向筋板和横向筋板形成的支撑面上。在该技术方案中,除了利用后桥壳体对法兰进行支撑之外,还能够通过纵向筋板、横向筋板对法兰起到支撑作用,这样就提高了法兰安装的接触面积,保证了法兰能够分别与多个纵向筋板和横向筋板连接可靠性,弥补了现有方案中,只能够通过后桥壳体对法兰进行支撑而导致支撑面不足的缺陷。
