Rear axle shell assembly

Abstract

The invention discloses a rear axle shell assembly. The rear axle shell assembly comprises a shell, wherein the shell comprises an upper airfoil surface, a lower airfoil surface, a front vertical surface and a rear vertical surface; the shell is of an integrally cast structure; the distance from each point of the lower airfoil surface to the central line of the shell is greater than the distance from the corresponding point on the upper airfoil surface to the central line of the shell. According to the rear axle shell assembly, the weight of an axle shell can be effectively reduced on the premise that the strength of the axle shell is guaranteed, and the waste of the material is avoided.
本发明公开了一种后桥桥壳总成,包括:壳体,所述壳体包括:上翼面、下翼面、前立面、后立面,所述壳体为整体铸造结构,所述下翼面上各点与壳体中心线的距离大于所述上翼面上对应点与壳体中心线的距离。本发明的后桥桥壳总成可以在保证桥壳的强度下,有效地降低桥壳的重量,并避免材料的浪费。
