Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide an automobile rear axle housing in view of the above-mentioned technical deficiencies, which adopts the method of setting a reinforcement case at the swelling part of the axle case, and setting a reinforcement bend at the mounting flange of the reinforcement case. side, which solves the problem of single wall thickness of the stamped and welded axle housing, which is prone to oil leakage and breakage during use
The invention also provides a process for processing the rear axle housing of an automobile, which adopts a flexible core frame in the bridge bag to be formed of a rectangular bridge tube, and performs mechanical bulging on the flexible core frame through the action of two punches on the upper and lower sides, so as to solve the problem of forming The process is complicated, and the deformation of the axle housing increases the workload of plastic surgery

The invention relates to the technical field of automobile parts manufacturing, in particular to an automobile rear axle housing and a processing technology thereof. It includes a bridge bag in the middle and a rectangular bridge tube arranged on both sides of the bridge bag. The front and rear sides of the bridge bag are respectively provided with a reinforcement cover, and the middle part of the reinforcement cover corresponds to the position of the bridge package. A flange plate is provided, the inner edge of the flange plate is protruded with a reinforced curved edge, and the rear side opening of the bridge bag is provided with a back cover, and the reinforced curved edge is embedded in the said rear cover after installation. inside the back cover. A reinforced cover is set at the expansion bag of the axle housing, and a reinforced flange is set at the mounting flange of the reinforced cover, which increases the resulting strength of the axle housing. Improved sealing performance and bond strength.
Description
technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automobile rear axle housing and a processing technology thereof. Background technique [0002] The axle housing is an important bearing and force-transmitting part in the automobile. Its main function is to support and protect the main reducer, differential and half shafts, etc., and requires high strength, rigidity and fatigue life. The automobile axle housing generally consists of an axle bag in the middle and an axle tube accommodating the half shafts on both sides; at present, it can be made by casting, stamping welding and steel tube expansion forming. The cast axle housing has high strength and rigidity, but is heavy, pollutes the environment during the production process, and consumes energy from consumables. The weight of the stamped and welded axle housing is lighter than that of the cast axle housing, but the wall thickness is single, which i...
