Abstract

The invention discloses a method for manufacturing a thin-plate high-load heavy-truck axle housing. The method includes the following steps that a 9.5 mm half-shell is put on line and is subjected toplane milling, groove milling and burr removing for preliminary treatment, and longitudinal seams generated by buckling of two half-shell sets are welded; pipa holes are cut and rounding inspection isperformed; the pipa holes are machined, reinforcement rings are welded, and then leveling is carried out; excess parts at the both ends of the axle housing are removed, alignment is carried out, oiland gas holes are drilled, shaft heads are welded at the both ends of the axle housing, and then straightening is carried out; trimming lathing and flange welding are carried out, and then straightening is carried out; a back cover is welded, and then straightening is carried out; and accessories are welded, then straightening is carried out, the axle housing is cleaned and repaired to go offlineafter the axle housing is qualified, and otherwise corrections are made. The method can realize welding processing of the high-load axle housing with the thickness being 9.5 mm, deformation and stressof the welding process can be controlled, the axle housing bench test is qualified, a truck is safe and reliable, and the purpose of lightweighting the axle housing is achieved.

Description

technical field [0001] The invention belongs to the field of automobile parts manufacturing, and relates to an improvement of a lightweight manufacturing method of a heavy truck, in particular to a manufacturing method of a thin-plate high-load heavy truck axle housing. Background technique [0002] The axle housing is the basic part for the axle to install the final drive, differential, half shaft, wheel hub and suspension, and its main function is to support and protect. At the same time, the axle housing is one of the main components of the driving system. The axle is a key component of the vehicle quality, and its weight accounts for 11-16% of the total weight of medium-sized trucks, and it accounts for a larger proportion for heavy-duty trucks. The weight of the driving axle of ordinary heavy trucks largely depends on the structure of the axle housing. Therefore, reducing the weight of the driving axle housing is an important way to reduce the weight of the whole vehic...
