Abstract
The utility model provides a kind of back axle integral structure, it comprises rear bridge tube, described rear bridge tube two ends respectively and be symmetrical arranged Hose support, hind axle, damper bracket, leaf spring seat board and locating convex block, two ends of described rear bridge tube arrange described hind axle, rear bridge tube near described hind axle arranges damper bracket and leaf spring seat board, the opposite of described damper bracket arranges described Hose support, arranges described locating convex block above described leaf spring seat board.A kind of symmetrical expression compact back axle integral structure, design symmetry, reduces and repeats or similar part exploitation, save cost of development; Compact arrangement, saves arrangement space.
Description
Technical field
The utility model relates to automobile manufacturing field, particularly relates to a kind of back axle integral structure.
Background technology
Automobile axle is a very crucial part in Automobile Chassis Parts, for support wheel be connected rear wheel, play a part to bear vehicle rear load, therefore need enough strength and stiffness, to bear and to transmit the various force and moments acted between road surface and vehicle frame or vehicle body, rear axle structure wants simple simultaneously, and fabrication properties is good, easy to manufacture, easy to maintenance.The rear-suspension system of my company is generally the semi-independent suspension frame structure of multi link coil spring at present, and back axle is generally driving back axle, shown in Fig. 1 specific as follows.
But this structure exists following not enough:
Complex structure, takies too much space, be unfavorable for that chassis is arranged, and manufacturing cost is higher, and maintenance is inconvenient, is not suitable for the demand of low cost loading car.
Existing patented technology (the non-driven back axle 201020620880.X for automobile), existing patent structure arrangement of parts is loose, takies larger chassis arrangement space, is not suitable for compact sedan and arranges.
Utility model content
In order to solve problem in prior art, the utility model provides a kind of symmetrical expression compact back axle integral structure, design symmetry, reduces and repeats or similar part exploitation, save cost of development; Compact arrangement, saves arrangement space.
A kind of back axle integral structure, it comprises rear bridge tube, described rear bridge tube two ends respectively and be symmetrical arranged Hose support, hind axle, damper bracket, leaf spring seat board and locating convex block, two ends of described rear bridge tube arrange described hind axle, rear bridge tube near described hind axle arranges damper bracket and leaf spring seat board, the opposite of described damper bracket arranges described Hose support, arranges described locating convex block above described leaf spring seat board.
As further improvement of the utility model, described rear bridge tube is integrally-built cylinder.
As further improvement of the utility model, described hind axle line of centers is higher than the line of centers of rear bridge tube.
As further improvement of the utility model, described hind axle is symmetrical structure.
The beneficial effects of the utility model are: on the basis of existing product structure, design a kind of brand-new symmetrical expression compact beam rear axle, and this structure rear axle can not only reduce repetition or similar part exploitation, saves cost of development; And owing to taking compact arrangement, can also arrangement space be saved.Simultaneously the integrally-built rear bridge tube axle housing that instead of punching press, be welded, improves Rigidity and strength; By making hind axle line of centers higher than back axle tube hub line, thus improve the line of centers of rear brake and rear tyre, improve the height of the roll center of back axle suspension, improve the roll stability of car load.

Fig. 1 is the structure of existing product;
Fig. 2 is the utility model back axle integrated symmetric formula structural representation;
Fig. 3 is the utility model hind axle design symmetry schematic perspective view;
Fig. 4 is the utility model hind axle design symmetry lateral plan;
Fig. 5 is the utility model back axle compact design schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 2 to 5, Fig. 2 is the utility model back axle integrated symmetric formula structural representation, this kind of new construction back axle is used for the non-driven back axle of automobile, it comprises rear bridge tube 1, be hind axle 3 at the two ends of rear bridge tube 1, the bridge tube 1 near hind axle 3 have left damper bracket 4, right damper bracket 7 and leaf spring seat board 5 successively, left damper bracket 4 be left Hose support 2 below, be right Hose support 8 after right damper bracket 7, leaf spring seat board 5 is locating convex block 6 above.
The axle housing that integrally-built rear bridge tube instead of punching press, is welded, improves Rigidity and strength; By making hind axle line of centers higher than back axle tube hub line, thus improve the line of centers of rear brake and rear tyre, improve the height of the roll center of back axle suspension, improve the roll stability of car load.
Back axle integral structure symmetrical expression designs, and reduces and repeats or similar part exploitation, save development time and cost; With the axle housing that solid drawn pipe substitutes punching press, is welded, not only reduce processing intensity and cost, and improve the Rigidity and strength of back axle.
Not only back axle is design symmetry, and hind axle is also take design symmetry, and same part both can be contained in the back axle left side also can be contained in the right; Hind axle line of centers, higher than back axle tube hub line, which improves the line of centers of rear brake and rear tyre, thus improves the height of the roll center of back axle suspension, improves the roll stability of car load.
Back axle compact arrangement designs, and hind axle, Hose support, damper bracket, leaf spring seat board, locating convex block compact Layout, in back axle the right and left, neither affect the assembling of part, can save a lot of arrangement space again, and the outward appearance of same back axle is also more attractive in appearance.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
