Abstract
The utility model relates to a constant velocity cardan joint, in particular to a rzeppa universal joint with the outer surface provided with conical faces, and mainly aims at solving the technical problems that a constant velocity cardan joint in the prior art is relatively complex in structure, not easy to assemble, not firm in connection, and the like. The rzeppa universal joint with the outer surface provided with the conical faces comprises an bell housing (1), and is characterized in that one end of the bell housing (1) is provided with a thread head (2), the outer surface of the other end of the bell housing (1) is provided with a plurality of sections of conical faces (3), a star-shaped sleeve (4) is arranged inside the bell housing (1), round arc faces (5) are arranged on the inner wall of the bell housing and the outer surface of the star-shaped sleeve, a steel ball (6) is connected on the round arc faces in sliding mode, and the steel ball is fixed inside the bell housing through a holder (7).
Description
Technical field
The utility model relates to a kind of constant velocity universal joint, especially relates to a kind of rzeppa universal joint of the outer surface belt conical surface.
Background technique
Rzeppa universal joint is that automobile is with the critical component in the constant velocity universal joint drive spindle; The usability of rzeppa universal joint and quality life-span directly influence the view of people to automobile itself; Along with popularizing of automobile, people require increasingly high to the travelling comfort of vehicle operation performance and use.For a long time, constant velocity universal joint exists all the time and is easy to generate noise and vibration, short-life defective in the using process.Chinese patent discloses a kind of rzeppa universal joint, and (notice of authorization number: CN2690657), it comprises outer race, star sleeve, retainer and steel ball, and retainer is contained in the outer race inner ball surface; Steel ball places in six fenestras of retainer; And contact with the star sleeve outer spherical surface, the outer race inner ball surface is made up of three sections variation circular arcs, and wherein the radius of arc at two ends is identical; The radius of arc of intermediate section is different from the radius of arc at two ends, these three sections smooth connections of circular arc; After the assembling, the outer spherical surface of retainer contacts with the circular arc at outer race inner ball surface two ends, has the gap between outer race inner ball surface intermediate section circular arc and retainer outer spherical surface.But this constant velocity universal joint structure is comparatively complicated, assembles comparatively difficultly, connects more insecure.
The model utility content
The utility model provides a kind of rzeppa universal joint of the outer surface belt conical surface, and it mainly is that to solve existing in prior technology constant velocity universal joint structure comparatively complicated, assembles comparatively difficultly, connects the technical problem of more insecure grade.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The rzeppa universal joint of the outer surface belt conical surface of the utility model; Comprise outer race, described outer race one end is provided with thread head, and the outer surface of the other end has the multistage conical surface; Outer race inside is provided with star sleeve; Outer race inwall and star sleeve outer surface are provided with arc surface, slidely connect steel ball on the arc surface, and steel ball is fixed on outer race inside through retainer.Can be connected with automotive hub through thread head, make that connection is comparatively firm.The outer race outer surface is the multistage conical surface, can more easily universal joint be encased in the Motor Vehicle.
As preferably, described outer race is provided with gyration center.
As preferably, described outer race middle part outer surface has involute outer spline, can be connected with the motor differential mechanism of automobile like this.
As preferably, described star sleeve internal surface has involute inner spline, can be connected with the axostylus axostyle of vehicle like this.
Therefore, the utility model is provided with thread head at an end of outer race, is convenient to it and wheel hub is fixed together, and can other parts of universal joint and Motor Vehicle be connected through external splines in the involute in addition, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Component, position and numbering among the figure: outer race 1, thread head 2, the conical surface 3, star sleeve 4, arc surface 5, steel ball 6, retainer 7, gyration center 8, involute outer spline 9, involute inner spline 10.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the rzeppa universal joint of the outer surface belt conical surface that this is routine like Fig. 1, has an outer race 1; Outer race one end is provided with thread head 2; The outer surface of the other end has the multistage conical surface 3, and outer race inside is provided with star sleeve 4, and outer race inwall and star sleeve outer surface are provided with arc surface 5; Slidely connect steel ball 6 on the arc surface, steel ball is fixed on outer race inside through retainer 7.Outer race is provided with gyration center 8.Outer race middle part outer surface has involute outer spline 9.The star sleeve internal surface has involute inner spline 10.
During use, at involute outer spline 9 place's junctor motor vehicle engine differential mechanisms of outer race 1, involute inner spline in star sleeve 4 10 connects the axostylus axostyle of automobiles bottom, the more whole device Motor Vehicle of packing into is got final product.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
