Abstract
The utility model discloses an axle housing of a stamping and welding structure. The axle housing is integrally formed by stamping an axle housing main body, an axle housing cover and a wall of an axle tube, wherein the wall of the axle tube is only provided with one lengthways welding line. The axle housing eliminates the manufacturing procedure and the welding procedure of a back cover and a triangular plate, is less in manufacturing procedures, is short in period, is low in cost, is good in integrity, is less in the welding line, is good in tightness, greatly improves the intensity and the fatigue life compared with the conventional axle housing, leads the carrying capacity of a rear axle assembly to be increased by about 15% compared with a rear axle with the conventional structure.
Description
Technical field
The utility model relates to a kind of automobile axle housing structure, is specifically related to a kind of press welding axle housing.
Background technology
Automobile axle housing production at present mainly contains four kinds of technologies, the one, adopt foundry technique, the 2nd, adopt skill towards the welder, go out the two halves axle housing respectively, the two halves shell is welded into an integral housing (does not contain the set square part as half shell, also need to weld set square), the 3rd, employing garden pipe is slotted, is rived, the process program of hole enlargement, shaping, undergauge, repair welding set square, and the 4th, adopt square tube, technology is rived, dilated to middle fluting.Along with developing of automobile industry, press welding axle housing is used for the production of axle housing in a large number.Traditional press welding axle housing assembly is made up of annexes such as the upper and lower body of axle housing, ring stiffener, axle housing lid, flange and spring blocks, process for making is loaded down with trivial details, the welding job amount is big, contaminated environment, especially flange diameter variation place easily forms stress concentration in the termination, cause termination flanged shaft fracture, the fatigue life of product is low, and seepage oil easily takes place.Therefore, how improving the intensity of axle housing and the fatigue life of prolongation axle housing is the problem that needs solution at present.
Summary of the invention
The purpose of this utility model provides welding of automotive axle housing behind a kind of monolithic molding, thereby increases the globality of axle housing greatly, improve axle housing intensity, prolong service life of axle housing.
For achieving the above object, the utility model is achieved by the following technical solution: a kind of punching press welded structure axle housing comprises: with the axle housing of the whole drawing of axle housing lid, the longitudinal seam on the central siphon wall.
This automobile axle housing relatively has following advantage with the present normally used punching press welded structure of people axle housing: this axle housing belongs to integrally formed and is welded, do not need other accessory structure, the manufacturing and the welding procedure of bonnet and set square have been saved, Fabrication procedure is few, cycle is short, cost is low, integrally formed good integrity, weld seam is few, good airproof performance, all be greatly increased at more former traditional axle housing aspect intensity and fatigue life, make the back axle assembly load-carrying capacity increase about about 15% than conventional confguration back axle.
Description of drawings
In order to make the utility model be convenient to understand, specific embodiment of the utility model is described in conjunction with the accompanying drawings now.
Fig. 1 is the structural representation of a preferred embodiment of punching press welded structure axle housing of the present utility model.
Fig. 2 is the pictorial diagram of the embodiment of punching press welded structure axle housing of the present utility model shown in Figure 1.
Fig. 3 is the shaped structure scheme drawing of the axle housing lid of preferred embodiment of the present utility model shown in Figure 1.
Fig. 4 is that the deburring of preferred embodiment of the present utility model shown in Figure 1 is dashed and lacked the stage structures scheme drawing.
Fig. 5 is the flange stage structures scheme drawing of preferred embodiment of the present utility model shown in Figure 1.
Fig. 6 is the whole stage structures scheme drawing of the side of preferred embodiment of the present utility model shown in Figure 1.
Each mark is represented respectively among the figure:
1. axle housing, 2. longitudinal seam, 3. axle housing lid, 4. central siphon wall, 5. plate embryo, 6. plate embryo limit, 7. breach, 8. axle housing sidewall, 9. mould, 10. retarder mounting hole.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
One preferred embodiment of punching type of the present utility model welding axle housing comprise axle housing 1, with axle housing 1 integrally formed axle housing lid 3, central siphon wall 4 and central siphon wall 4 on longitudinal seam 2.
Concrete processing technology of the present utility model is as follows:
(1) be shaped: stamp out the structure of axle housing lid 3 on plate embryo 5, the geomery of plate embryo 5 is determined by the size of required axle housing.
(2) deburring is dashed and is lacked: the centre that shear out as shown in the figure on plate embryo limit 6 is expanded, and the shape that two ends are narrower, and the at both ends midway location is gone out two breach.
(3) flange: with 6 bendings of plate embryo limit, form axle housing sidewall 8, the end of central siphon wall 4 is " U " shape.
(4) side is whole: utilize 9 pairs of axle housing sidewalls 8 of mould to do the processing that is shaped, form the shape of retarder mounting hole 10.
(5) shaping: further the axle housing that tentatively obtains is done orthopedic processing, obtain final products.
Claims (1)
1. punching press welded structure axle housing, comprise axle housing (1), axle housing lid (3), central siphon wall (4), it is characterized in that: axle housing (1), axle housing lid (3), central siphon wall (4) are the integrated punching shaped structure, have only a longitudinal seam (2) on the central siphon wall (4).
