Abstract
The utility model discloses an axle-tube light automobile axle housing, belonging to the technical field of the manufacturing of a light car. The utility model provides an axle-tube light automobile axle housing which can effectively avoid the damage of a half-axle oil-seal lip in the assembling process of a half-axle assembly. The axle-tube light automobile axle housing comprises half-axle bushing assemblies which are respectively installed on two ends of a reducer shell assembly, wherein a free end of each half-axle bushing assembly is respectively provided with a half-axle installation hole, a half-axle oil seal is respectively arranged inside each half-axle installation hole, the half-axle installation hole, on the inner side of the half-axle oil seal, is also provided with a half-axle installation supporting structure, and the diameter of an inner hole of the half-axle installation supporting structure is smaller than that of an inner hole of the half-axle oil seal.
Description
Technical field
The utility model relates to a kind of shaft tube type lilliput car axle housing, belongs to lilliput car manufacturing technology field.
Background technology
Half axle assembly of at present all shaft tube type lilliput car axle housings is installed on axle housing, because half axle assembly weight is larger, usually reach the 10Kg left and right, the workman in when operation due to half axle assembly tenesmus, cause half shafts section to damage the axle-shaft oil seal lip on the axle tube assembly, thereby oil leakage fault often appears in the automobile axle that general assembly is completed, the serious automobile that causes can't normally dispatch from the factory.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of in the fitting process of half axle assembly, the shaft tube type lilliput car axle housing that can effectively avoid the axle-shaft oil seal lip to damage.
For solving the problems of the technologies described above adopted technical scheme, be: a kind of shaft tube type lilliput car axle housing, comprise the axle tube assembly that is arranged on respectively reducing gearbox assembly two ends, free end at described each part axle tube assembly is provided with the semiaxis mounting hole, be furnished with axle-shaft oil seal in described semiaxis mounting hole, also be furnished with semiaxis mounting support structure on the semiaxis mounting hole of described axle-shaft oil seal inboard, the diameter of bore of described semiaxis mounting support structure is less than the diameter of bore of described axle-shaft oil seal.
Further, described semiaxis mounting support structure is the rapid wear oil seal seat be arranged on described semiaxis mounting hole, and the diameter of bore of described rapid wear oil seal seat is much smaller than the diameter of bore of described axle-shaft oil seal.
Further, described rapid wear oil seal seat is over-surplus fit structure with half axle assembly be arranged in described semiaxis mounting hole.
Further, described rapid wear oil seal seat is made by the rapid wear plastics.
The beneficial effects of the utility model are: by arranging semiaxis mounting support structure on the semiaxis mounting hole in described axle-shaft oil seal inboard, and make the diameter of bore of described semiaxis mounting support structure be less than the diameter of bore of described axle-shaft oil seal.Like this, in the fitting process of half axle assembly, when half larger axle assembly gravitate of weight drops, what at first collide is described semiaxis mounting support structure, thereby actv. has been avoided the damage of double shafting oil envelope lip of half axle assembly.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of shaft tube type lilliput car of the utility model axle housing
The A section enlarged drawing that Fig. 2 is Fig. 1.
In figure, be labeled as: reducing gearbox assembly 1, axle tube assembly 2, semiaxis mounting hole 3, axle-shaft oil seal 4, semiaxis mounting support structure 5, half axle assembly 6.
The specific embodiment
Be as shown in Figure 1 and Figure 2 the utility model provide a kind of in the fitting process of half axle assembly, the shaft tube type lilliput car axle housing that can effectively avoid the axle-shaft oil seal lip to damage.Described shaft tube type lilliput car axle housing comprises the axle tube assembly 2 that is arranged on respectively reducing gearbox assembly 1 two ends, free end at described each part axle tube assembly 2 is provided with semiaxis mounting hole 3, be furnished with axle-shaft oil seal 4 in described semiaxis mounting hole 3, also be furnished with semiaxis mounting support structure 5 on the semiaxis mounting hole 3 of described axle-shaft oil seal 4 inboards, the diameter of bore of described semiaxis mounting support structure 5 is less than the diameter of bore of described axle-shaft oil seal 4.Arrange semiaxis mounting support structure 5 by above-mentioned on the semiaxis mounting hole 3 of described axle-shaft oil seal 4 inboards, and make the diameter of bore of described semiaxis mounting support structure 5 be less than the diameter of bore of described axle-shaft oil seal 4.Like this, in the fitting process of half axle assembly 6, when half larger axle assembly 5 gravitates of weight drop, what at first collide is described semiaxis mounting support structure 5, thereby actv. has been avoided the damage of 6 pairs of axle-shaft oil seal 4 lips of half axle assembly.
In above-mentioned embodiment, in order to reduce production costs, do not affect again the use after described automobile axle housing has assembled simultaneously, described semiaxis mounting support structure 5 is set to be arranged on the rapid wear oil seal seat on described semiaxis mounting hole 3, and the diameter of bore of described rapid wear oil seal seat is much smaller than the diameter of bore of described axle-shaft oil seal 4, with advancing, described rapid wear oil seal seat and half axle assembly 6 be over-surplus fit structure, and described rapid wear oil seal seat is made by the rapid wear plastics.Like this, in the use procedure of described automobile axle housing postorder, as long as during half axle assembly work, once rotating, can make easily describedly to make the rapid wear oil seal seat by the rapid wear plastics and come off from described rear-axle casing, reduce the manufacturing cost of described semiaxis mounting support structure 5, can not affect again the use after described automobile axle housing has assembled.
