Description
Technical field
The present invention relates to be used to protect the guard shield of constant velocity universal joint; this constant speed universal joint for example is arranged on the live axle (power transmission shaft) that power can be passed to the vehicle bridge wheel hub from the differential gear of automobile etc., relates in particular to a kind ofly to be located at the outer surface of constant velocity universal joint shell and to be fixed on Sealing between the interior perimeter surface of larger diameter side end of the guard shield on this outer surface.
Background technique
Constant velocity universal joint has been used in for example opposed end place of automobile driving axle.In addition, also be connected with the flexible guard of the curved section that has covered constant velocity universal joint,, and prevent the foreign matter that comes from the outside such as the invasion and attack of dust and water so that sealing is used for the grease of lubricated constant velocity universal joint.The larger diameter side end of guard shield and smaller diameter side end are fastening respectively and be fixed on the outer surface of differential gear (differential mechanism) side of constant velocity universal joint shell (shell) or hub side and on the outer surface of drive shaft section with belt usually.
In general, the shell of outer surface with simple circle cylindrical shape is used on the hub side (outside) of constant velocity universal joint.
In this case, by on the interior perimeter surface that makes the larger diameter side end of being located at the constant velocity universal joint guard shield or the projection of therefrom stretching engage with the peripheral groove of upwards being located in the shell outer surface in week, just can prevent that the interior perimeter surface of constant velocity universal joint guard shield and the outer surface of constant velocity universal joint shell from moving each other, and they are sealed.
On the other hand, on the differential mechanism side (inboard) of constant velocity universal joint, usually used tripod joint (tripod joint) (three port joints), it constitutes by in trichotomous mode three groups of rollers for example being set axially slidably on the axial region of live axle.
In order to realize thinner and lighter effect, for example in the shell of tripod joint along circumferentially having formed three axial grooves in the mode of disperseing, they be arranged on outer surface axially on.In this case, for example formed in the interior perimeter surface of the larger diameter side end of constant velocity universal joint guard shield from the shape of axially looking outstanding conglobate thick portion, this thick portion can be adapted to the groove face of shell axial groove.
When using the tripod joint by this way, also consider, by make the peripheral groove that is formed in the shell with the outside in the projection that is formed on the shroud of identical mode engage, just can prevent that the outer surface of shell and the interior perimeter surface of guard shield from moving, and they are sealed.
Yet, when peripheral groove is formed in the groove face of the axial groove in the shell outer surface, existing when the preparation shell machining very complicated problems that becomes, this has just increased cost.
In order to address this problem, having known has following technological means, and it can prevent the sealing on mobile and the realization differential mechanism side (inboard).
That is to say, in the outer surface of larger diameter side end, be provided with the groove that is used for fastening belt, locate to be provided with a plurality of circumferential seal lips under the groove in the larger diameter side end on week, the larger diameter side end is by fastening piece such as belt and fix from outer circumferential side, the outstanding end of sealing lip is forced on the outer surface of shell, thereby has realized sealing.And, be arranged in the circumferential inside of guard shield on axially at sealing lip and be provided with anti-mobile recess, on the outer surface end of tripod joint shell, be provided with the projection that can engage with this anti-movable part, thus can prevent to move (for example see that Fig. 4 among day disclosure model utility communique No.62-16541 waits and day disclosure special permission communique No.2003-202034 in Fig. 1 etc.).
Yet these prior aries have following shortcoming.
1. depart from the position of preventing movable part in the axial direction because sealing lip is located at, so the volume of guard shield is bigger, has wasted material, and cost increases.In addition, guard shield also can't be satisfactory to the insertion performance in the shell.
2. because anti-movable part is located at the position of departing from the belt restraint location in the axial direction wittingly, therefore just can regulate towards the moving of guard shield smaller diameter side end, yet it is very little to be used to the power that moves of regulating towards the larger diameter side end.
In addition, the technology described in the patent documentation 2 also has following shortcoming.
3. in the axial groove of the outer surface of tripod joint shell, be provided with crimping (projection) therein and in the interior week of guard shield larger diameter side end, be provided with in the structure of the recess that can engage with crimping, because the existence of crimping, guard shield further descends to the insertion performance in the shell.
4. after forging, do not carry out turning processing.Therefore, the fuse of the guard shield that links to each other and the concentricity of the live axle in the shell descend, and all shortened the working life of guard shield in many cases.
5. because the recess that engages with crimping also is arranged among thick of larger diameter side end, so recess constituted back-off when moulding, the demoulding difficulty that becomes, formability can't be satisfactory.
6. because crimping still forms by forging, so the fluctuation ratio of dimensional accuracy is bigger in turning processing.Unless the recess of shroud is provided with the gap, otherwise this recess will drop on the crimping.Even when fastening belt, Sealing also can't be worked in some cases.
The present invention's development is used for solving the problem of conventional art, its objective is moving between the outer surface that prevents to have the constant velocity universal joint guard shield that forms thick portion outstanding from the interior perimeter surface of larger diameter side end and tripod joint shell, strengthen the sealability between them, further strengthen the insertion performance of guard shield in the shell, reduce the cost of guard shield material, make thereby realization reduces cost, the shell preparation cost is also convenient.

Should be noted in the discussion above that the peripheral groove 19 or the conical surface 21 are not formed among the above-mentioned axial groove 13b in the outer surface of shell 1.
Below, Fig. 3 is the view of outward appearance that has shown this embodiment's constant velocity universal joint guard shield.As shown in Figure 3, guard shield 25 is entirely formed as columniform shape, and has the larger diameter side end 27 on shell 1 one sides that are fixed on constant velocity universal joint, and is fixed on the smaller diameter side end 29 on the axial region one side (not shown) of live axle.And, between larger diameter side end 27 and smaller diameter side end 29, having formed bellows 31, it has flexibility and is configured to flexible.Should be noted that, in this embodiment, guard shield 25 is formed by rubber-like resin such as thermoplastic polyester based elastomeric, is less than or equal to the resin of hardness of the outer circumferential side of part outside the guard shield 25 such as larger diameter side end by hardness and forms and be located at the collar 23 on interior all sides of larger diameter side end.Yet the present invention is not limited to this example.For example, the main body of guard shield 25 can comprise the outer peripheral portion of larger diameter side end, and the collar can for example be waited integrally by molding and forming by identical resin material and forms.The collar 33 can be formed by rubber.
Bellows 31 is constructed such that the cylinder axis at guard shield 25 makes progress, promptly is provided with at upwardly extending convex portion 31a of week and recessed portion 31b on the Vertical direction in Fig. 3 repeatedly.That is to say that the cross section of bellows 31 is protruded on the outer circumferential side of convex portion 31a, and the cross section of bellows 31 is protruded on interior all sides of recessed portion 31b.For example be provided with five convex portion 31a in this embodiment, on a side of larger diameter side end 27, be provided with corresponding recessed portion 31b at each convex portion 31a.And the diameter of convex portion 31a and recessed portion 31b is set at 27 increases towards the larger diameter side end from smaller diameter side end 29.As a result, bellows 31 fully forms the shape of cone basically.
In the outer surface of larger diameter side end 27, be provided with the surface portion 35 that forms the external diameter that has substantial constant in the axial direction.
The opposed end place of the belt fastening part 35 that makes progress at the cylinder axis of guard shield 25 has formed step part 37,39, and it is used to prevent that belt from moving in the axial direction.
In addition, Fig. 4 is the view that guard shield 25 is looked from the end face side of larger diameter side end 27.As shown in Figure 4, formed on the interior perimeter surface of larger diameter side end 27 and outstandingly to be circular thick 41, they can be adapted to be formed on the groove face of the axial groove 13b in the outer surface of shell 1.Should be noted in the discussion above that for simplicity the zone except that thick 41 on the internal surface of this larger diameter side end 27 will be called thin portion 43 hereinafter.
Fig. 5 is the sectional view of arrow V-V in Fig. 4, and is the zoomed-in view of guard shield 25 in the thin portion 43 of larger diameter side end 27.As shown in Figure 5, in thin portion 43, the interior perimeter surface of larger diameter side end 27 forms down and is recessed into roughly trapezoidal cross-sectional shape, forms corresponding to this trapezoidal upper base and surface portion 45 with maximum inner diameter and makes its internal diameter substantial constant in the axial direction.
And, surface portion 45 axially on opposed end on formed outstanding sealing lip 47,49.
The sectional shape of sealing lip 47,49 is a triangle, and as shown in Figure 5, its outstanding end (apex portion) is circular, yet the present invention is not limited to this example.And the outstanding end on guard shield 25 axial (width direction of sealing lip 47,49) in the corresponding sealing lip 47,49 roughly is in the middle part of sealing lip.
And, on guard shield 25 the opposite side on axially, formed the conical surface 51,53 with respect to the surface portion 45 which is provided with above-mentioned sealing lip 47,49.When the guard shield 25 with this embodiment's constant velocity universal joint is inserted in the shell 1 of above-mentioned tripod joint, these conical surfaces 51,53 bear against respectively on the conical surface 19a of peripheral groove 19 of outer surface 13 of the conical surface 21 on the edge of the open end 3 that is formed at shell 1 and shell 1.The anti-moving end-wall of these conical surface that leans on mutually 51,53 effects, it can prevent that guard shield 25 from moving in the axial direction with respect to shell 1.These conical surfaces 51,53 form and its internal diameter is increased along with the distance from sealing lip 47,49 and reduce.
Should be noted in the discussion above that in this embodiment the conical surface 51,53 has been arranged to consider the insertion performance when connecting, however these surfaces can on the diametric(al) of larger diameter side end 27, vertically be provided with, these designs can change within the scope of the invention.
These conical surfaces 51,53 will be called anti-moving end- wall 51,53 hereinafter.
In addition, sealing lip 47,49 and anti-moving end-wall (conical surface) 51,53 be arranged on belt fastening part 35 under.
And Fig. 6 is the sectional view of arrow VI-VI in Fig. 4, and is the zoomed-in view of guard shield 25 in thick 41 of larger diameter side end 27.
As shown in Figure 6, in this embodiment, the anti-moving end-wall (conical surface) 51,53 that is similar in the thin portion is not set in thick 41, but on thick 41 surface 55, has formed sealing lip 47,49 yet.
That is to say that sealing lip 47,49 is formed on the whole circumference of interior perimeter surface of larger diameter side end 27, no matter be on thick 41 or in thin portion 43.Should be noted in the discussion above that the zone that is provided with these sealing lips 47,49 forms on thick 41 surface 55 and axially to have a substantially the same sectional shape along guard shield 25.
Fig. 7 A and 7B have shown that guard shield is connected/is fixed on the state on the shell 1 of tripod joint, wherein Fig. 7 A has shown according to this embodiment's constant velocity universal joint guard shield and the relation between the tripod joint shell, and Fig. 7 B has shown the relation between traditional guard shield and the tripod joint shell.Fig. 8 A is the zoomed-in view of the major component of Fig. 7 A, and Fig. 8 B is the zoomed-in view of the major component of Fig. 7 B.
Therefore, will introduce the comparison of this embodiment (Fig. 7 A and 8A) and traditional approach (Fig. 7 B and 8B) below.
In this embodiment, sealing lip 47,49 is arranged between the anti-moving end-wall 51 and 53.On the other hand, in traditional approach, as seen in from Fig. 8 B, anti-mobile recess 301 is arranged on for sealing lip 302 is located at the position of guard shield 300 on axially in the position of bias internal.And the projection 201 that engages with anti-mobile recess 301 is arranged on the end of the outer surface on the tripod joint shell 200.In this structure, the volume of guard shield is very big in conventional art, and this has just wasted material, and the insertion performance in shell also can't be satisfactory.On the other hand, according to this embodiment, thickness is less, and volume is also less, therefore can waste material, and the insertion performance in shell is also very good.
And in conventional art, above-mentioned anti-moving structure (201 and 301) departs from belt fastening part 400 (adopting label 500 to represent belt in the figure) wittingly.Therefore, though can regulate guard shield 300 towards the smaller diameter side end move (the L direction moves in figure) time, yet it is also very little to be used for the power that moves (along moving of figure R direction) of regulating towards the larger diameter side end.On the other hand, in this embodiment since anti-moving end- wall 53,51 and sealing lip 49,47 be arranged on belt fastening part 35 under, so the fastening force of belt 63 acts on front/rear anti-moving end- wall 53,51 and the sealing lip 49,47.Therefore, can regulate moving on any direction of forward/backward in the axial direction, and sealability is also very good.
As mentioned above,, only need on the outer surface 13 of constant velocity universal joint shell 1, carry out machining, not need forging plane is carried out the surface finishing that unavoidably will carry out of micro-cutting surplus the peripheral groove 19 and the conical surface 21 according to this embodiment.Simplify the effect of amount of finish when therefore, can be implemented in the manufacturing of constant velocity universal joint shell 1.
Fig. 8 C has shown that the shell 1 (with the part shown in the solid line) of the tripod joint of using in this embodiment is stacked and placed on the tripod joint of using in traditional approach shell (with the part shown in the double dot dash line) goes up with the view of the state of machining allowance relatively.Owing to needn't cut by the part shown in the figure section line A in this embodiment, therefore more economically.
And sealing lip 47,49 can bear against on the larger-diameter surface portion of having of tripod joint shell 1 (projection) 23.Therefore, in each sealing lip 47,49, and surface portion (projection) 23 contacted parts and and the contacted part of axial groove 13b between border 17 in bend angle reduce.Therefore just can strengthen sealability.This principle is introduced with reference to figure 9.Fig. 9 is the view of axially watching shape of the groove face of axially watching shape and axial groove 13b of the bottom surface of axially watching shape, peripheral groove 19 of shape, the surface portion 23 (by the formed surface of machining mother metal) of the outer surface that shown the mother metal of the shell 1 among this embodiment (by forging the surface that forms).Outer surface shape by the mother metal that forges the shell 1 that forms is illustrated by solid line 101.The surface configuration with sealing lip 47,49 contacted surface portions 23 in the shell 1 is illustrated by dotted line 103.In addition, the surface configuration on the bottom land surface of peripheral groove 19 is illustrated by single-point line 105.And sealing lip 47,49 for example can be configured to join with peripheral groove 19, and the external diameter of peripheral groove 19 can form very little by the surface of cutting shell 1.In this structure, sealing lip 47,49 bends to relatively large angle beta on the bottom land surface of peripheral groove 19 and surperficial contacted point 107 places of axial groove 13b.When sealing lip 47,49 bent to relatively large angle by this way, the sealability in this curved section will descend.On the other hand, in this embodiment, sealing lip 47,49 is in the surface of surface portion 23 and the surperficial contacted point 109 places bending of axial groove 13b, but therefore its bend angles alpha can think that than littler in the bending angle at point 107 places sealability improves.
In addition, according to this embodiment, the surface portion 45 in being in of larger diameter side end 27 on all sides and can form very thin as the thin portion 43 between the belt fastening part 35 on the outer circumferential side at the back side.Therefore, can alleviate the weight of guard shield 25, and reduce used material.And the rigidity of larger diameter side end 27 descends, and this part becomes pliable and tough, therefore helps the attended operation in the shell 1.
In addition, the guard shield 25 that comprises smaller diameter side end 29, bellows 31 and larger diameter side end 27 is mainly formed by resin, and the collar 33 is formed by the material of hardness less than the hardness of the resin that forms guard shield 25, and sealing lip 47,49 can be by forming with the collar 33 identical materials.Therefore, can reduce the hardness of sealing lip 47,49, thereby guarantee enough elastic deformation amounts, and therefore strengthen sealability significantly.
Should be noted in the discussion above that the present invention is not limited to the foregoing description, but can suitably change within the scope of the invention.For example, the projection as sealing lip can form another kind of shape.The quantity of projection is not limited to two among this embodiment, but can be still less or more.In this case, when increasing the quantity of projection, can further strengthen sealability.In addition, the collar can be formed by rubber, and another part can be formed by resin, and whole guard shield can only be formed by rubber or resin.
