Abstract
The utility model relates to a universal-joint, in particular to a cold extruding cross-pin universal-joint assembly. The assembly mainly solves the problems that the universal-joint in the prior art is generally made from hot forging, truning is also needed after hot forging, procedures are more complicated, and the production cost is higher. The assembly also solves the technical problems that the hermetic performance of an oil seal cannot reach the requirements after cold extruding for universal-joints. The assembly comprises a cross-pin (1), wherein four end portions of the cross-pin (1) are provided with shaft sleeves (2), needle rollers (3) are arranged in the shaft sleeves, the oil seal (4) is arranged between the inner end of the shaft sleeve (2) and the root portion of the cross-pin (1), the oil seal is of 'X' shape, and four sealing lips are respectively contacted on a cross-pin body, a cross-pin root portion, a cross-pin shaft body and the shaft sleeves.
Description
Technical field
The utility model relates to a kind of universal joint, especially relates to the isostructural improvement of a kind of cold hobbing Hooke's joint assembly.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high strength Hooke's joint (notice of authorization number: CN 2464984Y), it comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer, the end of outer ring is provided with packing holder, is provided with seal ring skeleton and seal placed on it on described packing holder; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and three lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, and the needle roller end face ring with place the cross axle spindle nose end face of needle roller inboard in the same plane, the inboard of needle roller end face ring is provided with the pad chamber, it is built-in with glass nylon Composition spacer, and the exterior edge face of Composition spacer flushes substantially with described needle roller end face ring; The center line of grinding undercut and bottom plane, outer ring are 35 °～55 ° angles, and its degree of depth is 0.25～0.6mm, and the end is the circular arc ring that radius is 0.3～5.0mm.But this Hooke's joint generally is to be made by forge hot, also needs to carry out cylindrical turning after the forge hot, and operation is comparatively miscellaneous, and cost of production is also higher.
The model utility content
The utility model technical issues that need to address provide a kind of cold hobbing Hooke's joint assembly, it mainly is to solve the existing in prior technology universal joint, generally is to be made by forge hot, also needs to carry out cylindrical turning after the forge hot, operation is comparatively miscellaneous, and cost of production is problem of higher also; The utility model also solved universal joint with cold hobbing after, the sealing of oil sealing does not reach the technical problem of requirement etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cold hobbing Hooke's joint assembly of the present utility model, comprise cross axle, four ends of cross axle are provided with axle sleeve, be provided with needle roller in the axle sleeve, it is characterized in that being provided with oil sealing between described axle sleeve the inner and the cross axle root, oil sealing is " X " shape, and its four sealing lips contact respectively on cross axle body, cross axle root, cross axle axis body, axle sleeve.Cross axle generally comprises the body of hollow, and uniform criss-cross axis body on the body.Axle sleeve, needle roller are formed bearing, and it is socketed on the cross axle.Because cross axle has adopted cold-extrusion technology, oil sealing originally is just inapplicable, and therefore the luggage with oil sealing is designed to " X " shape.The oil sealing of " X " shape has four sealing lips of diverging, and the footpath upwards is in two outside sealing lip height and is higher than two sealing lip height that are in inside.
As preferably, described axle sleeve outer end is cambered outwards circular arc.Axle sleeve the inner is bent inwardly into the needle roller back-up ring that blocks needle roller.
As preferably, be provided with buffer stopper between the end of described cross axle axis body and the end of axle sleeve.Buffer stopper has increased the weight of cross assembly and has been contained in the moment that joint is stuck, and weakens axial motion in use.Because the elasticity of buffer stopper is better than oil sealing, therefore prolonged service time greatly.
As preferably, the end of described cross axle axis body has cavity, and buffer stopper places in the cavity, and stretch out on the inwall that cavity withstands on axle sleeve the buffer stopper outer end.Buffer stopper withstands between cavity and the axle sleeve, and buffer stopper only moves in the cavity of cross axle axis body like this, prevents that it from shifting to other position after stressed.
Therefore, the utlity model has Hooke's joint and process, reduced the operation of cylindrical turning by cold hobbing, manufacturing efficiency is higher, and cost of production is lower, and the oil sealing that adopts is " X " shape, can play the better seal effect, characteristics such as simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: cross axle 1, axle sleeve 2, needle roller 3, oil sealing 4, buffer stopper 5.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of cold hobbing Hooke's joint assembly of this example, as Fig. 1, a cross axle 1 is arranged, four ends of cross axle are provided with axle sleeve 2.As Fig. 4, be provided with needle roller 3 between axle sleeve 2 and the cross axle 1, axle sleeve the inner bends to the needle roller back-up ring that can locate needle roller.Axle sleeve 2 outer ends are cambered outwards circular arc, and are provided with buffer stopper 5 between the inwall of axle sleeve 2 ends and the cross axle axis body end.Cross axle 1 axis body end has cavity, and buffer stopper 5 places in the cavity, and its outer end withstands on axle sleeve 2 inwalls.Be provided with oil sealing 4 between the inner of axle sleeve 2 and cross axle 1 root, oil sealing is " X " shape, and its four sealing lips contact respectively on cross axle body, cross axle root, cross axle axis body, axle sleeve.
During use, the utility model packed into to get final product in the Motor Vehicle.
