Description
Technical field
The utility model relates to a kind of vehicle driving axle housing, belongs to Machining Technology field.
Background technology
At present, the hot pressing of domestic and international production or the driving axle housing be made of colding pressing, be generally transition between cross section and cross section wall thickness homogeneous phase with, namely the axle housing housing of driving axle housing and the cross section wall thickness of the central siphon that is connected to axle housing housing two ends consistent, because driving axle housing is as the main force transmission element of automobile and load member, not only support the load-carrying of automobile, load is passed to wheel, also bear by the tractive force driving wheel to pass over, braking force, side force, the counter-force of vertical force and counter torque, for same cross-sectional thickness driving axle housing regional area stressed unsmooth, stress concentration phenomenon can be produced, very easily cause axle housing housing weak area, flange region and the central siphon of axle housing housing rupture, in order to improve the quality of above-mentioned driving axle housing, improve driving axle housing intensity, take the mode increasing the overall wall thickness of axle housing at present, although this mode enhances the intensity of driving axle housing, but too increase the weight of axle housing simultaneously, and wall thickness is thicker also can bring certain difficulty to shaping.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of structure simple, the driving axle housing that lightweight and mechanical strength is high, and to solve in prior art, driving axle housing global sections wall thickness is comparatively large, weight is large and the problems such as difficult forming.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of driving axle housing, comprise the shaping axle housing housing of integrated punching and be arranged on the central siphon at described axle housing housing two ends, it is characterized in that, described axle housing housing comprises the body section and flange section that connect as one, described body section comprises the first noumenon section connected successively, second body section and the 3rd body section, described the first noumenon section, second body section, 3rd body section, natural transition between the cross section of flange section and central siphon, in the first noumenon section, second body section, in the cross section wall thickness of the 3rd body section and flange section, the cross section wall thickness of described second body section is maximum.
Further, described 3rd body section cross section wall thickness is X, and described second body section cross section wall thickness is X+B, wherein, and 8<X<40mm, 0<B≤4mm.
Further, the cross section wall thickness of described the first noumenon section is X+A, and the cross section wall thickness of described flange section is X+C, and the cross section wall thickness of described central siphon is X+D, wherein 0≤A<C<B≤D4mm.
The beneficial effects of the utility model are: concentrate the cross section wall thickness of carrying to position second body section of weakness to increase to easily producing stress separately, the flange section relatively weak for carrying and the cross section wall thickness of central siphon also thicken, achieve the effect of the enhancing of overall driving axle housing intensity, also meet the overall weight-saving requirement of driving axle housing simultaneously.
