Abstract
The utility model discloses a counteractive rod support welding structure. The counteractive rod support welding structure comprises a counteractive rod support and an axle housing, and is characterized in that the counteractive rod support is provided with a gap which is positioned in the center of a welding part between the counteractive rod support and the axle housing; two sides of the gap are respectively welded with the axle housing through welding seams. According to the counteractive rod support welding structure, the welding stress and the deformation can be reduced, the stressed states of the welding seams are improved, and the crack failure rate of the axle housing is reduced.
Description
Technical field
The utility model belongs to automotive field, is specifically related to a kind of back reaction rod support welding structure.
Background technology
At present, China's heavy duty truck more than 90% is steel plate punched welding axle housing with drive axle, and back reaction rod support welding is on axle housing, and weld seam is one whole section, and after shell welding, deflection and internal stress are larger like this, and the easy crackle in commissure causes a whole set of axle housing to scrap.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency of the prior art, and a kind of back reaction rod support welding structure is provided.
The technical solution of the utility model is: a kind of back reaction rod support welding structure, comprise back reaction rod support and axle housing, it is characterized in that described back reaction rod support is provided with breach, described breach is positioned at back reaction rod support and center, shell welding position, and breach both sides and axle housing are each adopts one section of weld seam to weld.
The beneficial effects of the utility model are: back reaction rod support of the present utility model and shell welding punishment are two sections, be divided into two sections relatively short weld seams by a traditional long section weld seam, therefore reduce weld seam internal stress and welding deformation, reduced axle housing crack fault rate, extended service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further to disclose.
Embodiment 1
A kind of back reaction rod support welding structure, comprise back reaction rod support 1 and axle housing 2, described back reaction rod support 1 is provided with breach 3, and described breach 3 is positioned at back reaction rod support 1 and axle housing 2 centers, weld, and breach 3 both sides and axle housing 2 are each adopts one section of weld seam to weld.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited to above-mentioned giving an example, those of ordinary skill in the related art, in essential scope of the present utility model; variation, remodeling, interpolation or the replacement made, all should belong to protection domain of the present utility model.
Claims (1)
