Abstract
The utility model discloses a rear axle housing structure of a commercial vehicle. The rear axle housing structure of the commercial vehicle comprises a rear axle housing body. Hydro-pneumatic spring cylinder support frames are respectively arranged on rear portions of two ends of the rear axle housing body. Meanwhile, a steady trussing support frame is additionally arranged on the rear axle housing body. In order to match with a suspension system which uses a hydro-pneumatic spring cylinder as an elastic element, the hydro-pneumatic spring cylinder support frame is additionally arranged in the rear of a traditional rear axle housing and used for tightly fixing the hydro-pneumatic spring cylinder on a rear axle so as to improve rigidity and bearing capacity of the whole suspension system and comfort of the whole vehicle. Compared with a traditional steel sheet spring, the rear axle housing structure fixes the whole hydro-pneumatic spring cylinder on the rear of the rear axle and enables elastic elements of the suspension system to be compact and concentrated so that other surrounding parts can be arranged reasonably. The rear axle housing structure of the commercial vehicle is simple in structure, convenient to install and capable of solving the problem of fixation of the hydro-pneumatic spring cylinder.
