Description
Technical field
The present invention relates to a kind of single spheroid constant velocity universal joint drive spindle assembly.
Background technique
The constant velocity universal joint drive spindle assembly that current car assembles comprises fixed end universal joint, semiaxis, dirt-proof boot, sliding end universal joint assembly, wherein, dirt-proof boot is corrugated, and its one end is fixed on semiaxis by clip, and the other end is fixed on the housing of fixed end universal joint by clip.The constant velocity universal joint drive spindle assembly of this structure, needs to make dirt-proof boot fix on semiaxis and fixed end universal joint with pliers clamping stirrup when assembling dirt-proof boot, and assembly technology is complicated.Moreover this dirt-proof boot is corrugated, namely semiaxis becomes larger angle with fixed end universal joint when the vehicle is turning, and the wave pitch of this dirt-proof boot side can reduce even can stack, and timing is returned in direction, and dirt-proof boot restores.So repeatedly, then easily cause dirt-proof boot fatigue aging and breakage, the working life of dirt-proof boot is shortened.Usually, semiaxis also adopts shaft block ring make semiaxis keep relative fixing with the star sleeve of fixed end universal joint, and adopt sliding end universal joint that semiaxis can be moved axially at differential mechanism end.The constant velocity universal joint drive spindle assembly complex structure of this structure, assembly process are many, increase car manufacturing cost.
Summary of the invention
In order to overcome the deficiency of background technique, the invention provides a kind of dirt-proof boot long service life, the simple single spheroid constant velocity universal joint drive spindle assembly of structure.
The technical solution used in the present invention is: a kind of single spheroid constant velocity universal joint drive spindle assembly, comprises universal joint, semiaxis, and the housing outer surface of described universal joint has ectosphere face; Also comprise the dirt-proof boot be made up of all flat material in mountain, the internal surface of described dirt-proof boot has the inner ball surface portion suitable with described ectosphere face, described dirt-proof boot one end is fixed on described semiaxis, on the ectosphere face that the other end is overlapped on described housing and the opening end of described housing described housing when described dirt-proof boot rotates drop on all the time in described dirt-proof boot.
On the basis of such scheme and as the preferred version of such scheme: described dirt-proof boot is made up of all flat material in mountain.
On the basis of such scheme and as the preferred version of such scheme: be provided with lug boss at the internal surface of described dirt-proof boot near open end, the ectosphere face of described lug boss and described housing offsets.
On the basis of such scheme and as the preferred version of such scheme: described lug boss and described ectosphere face are in linear contact lay.
On the basis of such scheme and as the preferred version of such scheme: described lug boss is M shape, V-arrangement or fan-shaped along the cross section on described dirt-proof boot axial direction.
On the basis of such scheme and as the preferred version of such scheme: also comprise spring ring, be provided with recess at the outer surface of described dirt-proof boot near open end, described spring ring is arranged on described recess.
On the basis of such scheme and as the preferred version of such scheme: described universal joint also comprises star sleeve, and described star sleeve and described semiaxis realize being in transmission connection by means of only spline tooth structure, and described semiaxis can move along the axial direction of described star sleeve.
The present invention compared with prior art its beneficial effect is: the present invention adopts the universal joint with ectosphere face and the dirt-proof boot matched with this universal joint, when the angle that universal joint and semiaxis are formed changes, then by relatively rotating the angle change adapting to universal joint and semiaxis, there is not the situation of dirt-proof boot distortion in dirt-proof boot and universal joint.Therefore this dirt-proof boot effectively avoids fatigue aging, makes the long service life of dirt-proof boot and this drive shaft assembly structure is simple.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in Figure 1, a kind of single spheroid constant velocity universal joint drive spindle assembly of the present invention, comprise universal joint 1, semiaxis 2, the outer surface of the housing 3 of described universal joint has ectosphere face 4; Also comprise dirt-proof boot 5, the internal surface of described dirt-proof boot 5 has the inner ball surface portion 6 suitable with described ectosphere face 4, described dirt-proof boot one end is fixed on described semiaxis 2, on the ectosphere face 4 that the other end is overlapped on described housing and the opening end 11 of described housing described housing when described dirt-proof boot rotates drop on all the time in described dirt-proof boot 5.On the ectosphere face that the present invention adopts dirt-proof boot to be overlapped on housing and the opening end of described housing described housing when described dirt-proof boot rotates drops in described dirt-proof boot all the time, make the space between universal joint and dirt-proof boot with opposing seal, reach dust-proof object, moreover the inner ball surface portion structure that the present invention adopts ectosphere face and matches with this ectosphere face, when the angle that universal joint and semiaxis are formed changes, make universal joint and dirt-proof boot by relatively rotating to adapt to the angle change of universal joint and semiaxis, and there is not the situation of dirt-proof boot distortion, therefore this dirt-proof boot effectively avoids fatigue aging, make the long service life of dirt-proof boot.
In such scheme, dirt-proof boot preferably adopts all puts down (Santoprene) material by mountain and makes.Similarly, also can be made up of other material.
As shown in Figure 2, in the cavity entered between housing and dirt-proof boot to prevent dust, be provided with lug boss 7 at the internal surface of described dirt-proof boot near open end, the ectosphere face 4 of this lug boss and described housing offsets.
In order to reach dust blowing better effects if, effectively avoid dust to enter object in cavity, this lug boss 7 and ectosphere face 4 are in linear contact lay.As shown in Figure 2, described lug boss is M shape along the cross section on described dirt-proof boot axial direction, similarly, also may adopt V-arrangement or fan-shaped.Certain lug boss also can adopt other shape, but adopts M shape, V-arrangement or fan-shaped structure, and lug boss and ectosphere face form linear contact lay, dust blowing better effects if, effectively avoid dust to enter in cavity.
In order to make dirt-proof boot more firmly be fixed on housing, as shown in Figure 3, also comprise spring ring 8, be provided with recess 9 at the outer surface of described dirt-proof boot near open end, described spring ring is arranged on described recess.
Further, described universal joint also comprises star sleeve 10, and described star sleeve and described semiaxis realize being in transmission connection by means of only spline tooth structure, and described semiaxis can move along the axial direction of described star sleeve.Single spheroid constant velocity universal joint drive spindle assembly of this structure, eliminate in conventional ADS driving axle assembly for making semiaxis and star sleeve keep relatively-stationary shaft block ring, semiaxis and star sleeve is adopted to realize being in transmission connection by means of only spline tooth structure, utilize the feature that semiaxis can slide axially relatively with the spline tooth on star sleeve, in order to compensate moving axially of semiaxis, thus sliding end universal joint can be omitted.During use, semiaxis is directly inserted differential mechanism end to realize being in transmission connection, universal joint and hub bearing are in transmission connection.Therefore, the present invention has the advantages that structure is simple, user cost is lower.
The present embodiment should not be considered as limitation of the present invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
