DETAILED DESCRIPTION

[0018] It should be understood that the specific embodiments described herein are merely intended to explain the present application, and are not intended to limit the present application.

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figs. 1-3 As shown, a rear axle housing assembly with reinforcing ribs includes a rear cover 4 for accommodating the transmission structure; a middle section 3 of the axle housing is symmetrically connected and fixed to the rear cover 4; a stepped shaft 2 is fixed to the middle section 3 of the axle housing; a shaft head 1 is fixed to the stepped shaft 2; by providing multiple clearance grooves 7 and fixing holes 8 on the rear cover 4, the overall weight of the rear axle housing can be reduced; then, multiple second reinforcing ribs 10 are fixed to the inner plane of the rear cover 4; multiple first reinforcing ribs 9 are fixed to the inner arc-shaped surface of the rear cover 4, so that the thickness of the rear cover 4 can be reduced, thereby reducing the overall weight.

[0022] A fixed side plate 5 is symmetrically fixed to the middle section 3 of the bridge housing; multiple mounting holes 6 are provided on the fixed side plate 5.

[0023] Multiple third reinforcing ribs 11 are fixed to the outer surface of the back cover 4. The multiple third reinforcing ribs 11 reduce the weight of the back cover 4 while maintaining the structural strength of the back cover 4.
