Description
Technical field
The utility model relates to field of automobile, especially a kind of rear axle housing body be arranged on automobile.
Background technology
Automobile rear axle housing generally has cast housing, punching weldering housing two kinds, cast housing is made up of cast steel or vermicular iron, it is large to there is stock left for machining in this cast housing, manufacturing cost is high, quality is unstable, inherent quality is unstable, the problems such as reliability of service difference, due to the uncontrollability of cast housing inherent quality, cause the quality extremely unstable of cast housing, in Automobile Transportation process, back axle phenomenon of rupture happens occasionally, huge potential safety hazard is brought to vehicle driver, also certain economic loss is caused, at present, good terms of settlement is not still had to this problem, punching weldering housing cast housing of comparing has low cost of manufacture, manufacturing process is simple, the advantage that quality controllability is good, Fig. 1 is a kind of common automobile punching weldering rear axle housing body, wherein spring perch 21 is welded on rear axle housing body, rear axle housing body is formed by two symmetrical upper half-shell 22 and housing lower half 26 butt welding, the cylindrical of upper half-shell 22 and housing lower half 26 is smooth arc surface, rear axle housing body is connected by weld seam 23 butt welding with axle tube 25, for ensureing the weld strength of butt welding place weld seam, reinforced company's female connector 24 is increased at the inner chamber of rear axle housing body and axle tube 25, the intensity of rear axle housing body is increased to some extent, , still often there is the problem of back axle fracture in Automobile Transportation process, bring very large potential safety hazard to automobile, also cause certain economic loss in the defect of this punching weldering housing due to structure existing.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile rear axle housing, and it can solve current automobile and rush poor, the normal problem that fracture occurs of postwelding axle shell intensity and toughness.
In order to solve the problem, the technical solution adopted in the utility model is:
A kind of automobile rear axle housing, comprise upper half-shell and housing lower half, described upper half-shell and housing lower half butt welding are connected into hollow rear axle housing body, described upper half-shell outside is provided with spring perch, the two ends of described rear axle housing body extend vertically, this extension is the cylinder pipeline section that diameter is less than described rear axle housing body cross-sectional diameter, and be arc transition between this cylinder pipeline section and described rear axle housing body, the outer face of described cylinder pipeline section is connected with small circle ring; Described rear axle housing body outside face is connected with braking convex shoulder near the excessive place of circular arc; Its wall of described rear axle housing body is provided with vertically the outer reinforced rib of circular arc of some projections, its inwall is provided with the interior reinforced rib of lath-shaped vertically.
In above technical scheme, further scheme can be: described cylinder pipeline section and described rear axle housing body entirety compressing, the cylindrical of wherein said cylinder pipeline section is provided with some sections of axle journals.
Further: described outer reinforced rib and described upper half-shell, the common one of housing lower half are compressing, and described interior reinforced rib is welded on the madial wall of described upper half-shell, housing lower half.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, rear axle housing body and axle tube were processed weld together again by the past by the utility model respectively, and making into unites two into one rear axle housing body and axle tube makes one, only retains the port section of former axle tube, instead of the axle tube in original design; 2, adopt the automobile rear axle housing intensity and toughness of the utility model structure manufacture to increase, back axle phenomenon of rupture greatly reduces; 3, take the automobile rear axle housing of the utility model structure manufacture to reduce to some extent than original design manufacturing cost, automobile axle is extended service life.
