Description
Technical field
The present invention relates to a kind of tripod joint (Tripodegelenk) for transmitting torque between two axles rotated of angular misalignment each other.
Background technique
Tripod joint principle is known and has universal joint exterior part (Gelenkau enteil) and three rolling elements (Rollelement), it can move relative to universal joint exterior part.These rolling elements to be arranged in the inside of universal joint exterior part and translationally can to balance the dislocation of two axles in its axial direction.In addition, each rolling element has the receiving bore for bearing journal (Zapfen).This axle journal is a part for driven shaft, and driven shaft can be connected with each rolling element in like fashion.The angular misalignment between driven shaft and the axle be connected with universal joint exterior part may be made to become possibility via axle journal.In other words, known tripod joint is used for balancing the angular misalignment of two axles and movement along its axis and making the moment of torsion transmission between these two axles become possibility simultaneously.It is also known that rolling element is provided with backstop, its by between rolling element and universal joint exterior part, relative movement especially between the cage (Kaefig) and universal joint exterior part of rolling element is restricted on path of travel.Correspondingly, such backstop is implemented in known manner, to fix the first and second end positions.For two end positions normally running for this, rolling element does not leave the inside of universal joint exterior part on the one hand, and the motion of rolling element is also limited in the inside of universal joint exterior part on the other hand.
But can cause in the dynamic motion conditions of height, the relative movement between cage and the case of rolling element occurs in an undesired manner.In other words, this means, for strong especially between rolling element and universal joint exterior part or move fast especially, relative movement that is less desirable and that can not estimate may occur between cage and the case of rolling element.In like fashion, the preposition for the corresponding end position of normal path of travel also moves.According to the direction of this movement, this can cause, and rolling element can move outside predetermined path of travel relative to universal joint exterior part now.This especially can cause, and when sailing in universal joint exterior part, rolling element is in and contacts with the wall of universal joint exterior part, especially bottom wall.Such contact can cause, the other element of cage, case or rolling element due to this contact damaged.Especially in the universal joint exterior part of forging and in the inclination of the corresponding standard in universal joint exterior part place, this can cause, the rolling bearing region of cage curve inwardly and cause the friction that improves thus or cause rolling element be obstructed completely functional.In other words, in the result of the dynamic motion conditions of height, the so less desirable relative movement between cage and case can cause, and the parts of tripod joint or tripod joint can not use on the whole.
Summary of the invention
The object of the invention is the above-mentioned problem eliminating known tripod joint.In particular, the object of this invention is to provide a kind of tripod joint with universal joint exterior part and rolling element, it can be tackled (abfangen) and to move dynamically to the corresponding relative movement between case and height at the cage of rolling element and stop functional infringement of tripod joint.
Above object is realized by the tripod joint of the feature with independent claims 1.Other characteristic sum details of the present invention draws from dependent claims, specification and accompanying drawing.
Tripod joint according to the present invention has universal joint exterior part and at least one rolling element.In particular, in tripod joint according to the present invention, apply three rolling elements, it distributes with star.This at least one rolling element has cage and case (it is with the receiving bore of the axle journal for supporting tripod star (Tripodestern)).Via this axle journal it is possible that tripod star can be angled relative to the axle be connected with universal joint exterior part with the axle be connected therewith.In addition, there is the rolling element be associated with case being used for guide rail respect to one another (Laufbahn) place case being supported on universal joint exterior part.The rolling element that this rolling element is especially barrel-shaped or ball, it makes the support in the freedom of motion of the translation of rolling element become possibility.Rolling element keeps avoiding less desirable motion by cage, thus it makes dual rolling become possibility.Rolling element rolls on the other hand thus on the one hand on the guide rail of universal joint exterior part on the case of rolling element self.Therefore can say and produce case via cage to telescopic (teleskopartig) motion on rolling element, and vice versa.
Tripod joint according to the present invention is characterised in that, at least one safety backstop (Sicherungsanschlag) is arranged in the inside of universal joint exterior part and/or at universal joint exterior part place.The layout of safety backstop realizes like this in mode according to the present invention, makes to stop cage to contact with the wall of universal joint exterior part when cage moves relative to universal joint exterior part.Safety backstop namely independent of rolling element, especially independent of cage and the case of rolling element.Safety backstop is such as in the inside of universal joint exterior part and preferably independent of the normal path of travel of rolling element between two end positions.Preferably, only when there is high dynamic motion, less desirable relative movement namely between cage and the case of rolling element, safety backstop is just intervened.So ensured by the geometrical arrangements scheme of safety backstop, rolling element, especially its cage only can continue motion in like fashion, although it have left normal path of travel, however do not contact with the wall of universal joint exterior part.Its especially depended on wall is the bottom wall of universal joint exterior part at this.For this reason, safety backstop is such as installed in its inside at the side wall surface place of universal joint exterior part.
Safety backstop not only can construct a part for wall-forming in mode according to the present invention, and can construct discretely with this wall.In addition, except protective function, correction function (Rekalibrierungsfunktion) can also be met again by this safety backstop.If produce the relative movement between cage and rolling element in tripod joint according to the present invention, then path of travel moves.By this mobile restriction on the area, it is allow to safety backstop in the contact to be avoided of cage and universal joint exterior part.Correspondingly, calibrating again by performing by means of this restriction of safety backstop, that is, forcing relative movement conversely between cage and case.In other words, cage and case by cage is stopped at safety backstop place again with before because height produced relative movement movement on the contrary of moving dynamically is returned, near initial position.Not only can stop the mechanically deformation of cage in like fashion, and to calibrate in addition be also possible again, thus also can keep application when there is no additional maintenance or repair cost according to tripod joint of the present invention after height moves dynamically.
The stop surface of safety backstop is correspondingly configured in cage or its place.In particular, cage also has and is configured to the synergistic stop surface with safety backstop.Be configured in this accordingly especially geometrically and/or on region preparing like this, make to realize in safety backstop and cage, contact especially between its stop surface.Safety backstop in tripod joint according to the present invention is preferably arranged on the side wall surface place of universal joint exterior part at this.
Within the scope of this invention when in tripod joint according to the present invention, design cage makes it can move relative to universal joint exterior part between at least two end positions like this, can be favourable.This means, limited the standard path of travel of cage by two end positions, it is between these two end positions.In addition, in such form of implementation of the present invention, at least one safety backstop can be arranged in outside the region between these two end positions.The layout of this safety backstop is namely outside standard path of travel.In other words this means, cage can move in standard is run between these two end positions, and does not contact with safety backstop.Namely safety backstop does not engage with the cage of rolling element in normal operation, thus at all generation safety backstop and cage wearing and tearing or contact.When cage leave standard path of travel between two end positions and by exist cage impinge upon the risk at wall place of universal joint exterior part time, safety backstop just works on its protective function.Namely in the normal operation of tripod joint, safety backstop is not restrictive.Especially can trace back to the existing structure of tripod joint at this, thus also can apply this safety backstop as the remodeling function for so existing tripod joint.
When being configured with at least one safety backstop with the form of the jut on the wall of case exterior part in tripod joint according to the present invention, can be favourable equally.At this, this jut is especially configured in the side wall surface place of universal joint exterior part.This jut preferably constructs like this, makes when cage enters in the danger being in and contacting with wall, the especially bottom wall of universal joint exterior part, and this jut can geometrically and contact with cage partly at least piecemeal.The safety backstop of such structure especially cost-effective and can manufacturing simply.Like this be the so-called impression portion (Pr gewarze) on this wall with the manufacturing feasibility of the safety backstop of the form of the jut on the wall of universal joint exterior part.At this, produce such impression portion particularly by the impression on the outside of universal joint exterior part.Such impression on the outside of universal joint exterior part causes the distortion also on the inner side of universal joint exterior part, thus on the side wall surface of universal joint exterior part, be configured with corresponding jut, and it is used as safety backstop according to the present invention.Effect from the outside brings this advantage, namely also can reduce manufacture cost further.
When being configured with in tripod joint according to the present invention with at least one safety backstop of the form of groove (utilizing it to guide cage at least partly at least partially), can be favourable equally.This groove in the inside of universal joint exterior part is especially configured in the material of universal joint exterior part.Preferably, be provided with and enter inclined-plane (Einlaufschr ge), easily enter in this groove the rolling element that enables in other words with cage to enable cage easily in insertion groove.This guiding need not cover the whole standard operation area of rolling element forcibly at this, but is especially only configured in its end regions about the end position of the key of standard path of travel.In other words, when cage only to enter in groove and meets protective function in mode according to the present invention by groove after leaving standard path of travel, be enough.
When in tripod joint according to the present invention, cage has at least one guiding projection (it to join in groove and is configured to the stop at least one the safety backstop place at groove), it is another advantage.Such guiding projection such as can be configured to the protuberance of nose shape, and it fully or is at least partly guided through groove.In particular, such guiding projection angularly, especially at a right angle stretches out from cage about the moving direction of cage.What such form of implementation made the simplification of cage and universal joint exterior part is constructed to possibility, and groove and guiding projection can separately be adjusted in the other functional of cage and the rolling element that kept by cage.In addition, the form of implementation especially reliably of safety backstop is provided by the guiding of guiding projection in groove.
When being configured with at least one safety backstop by stopping element (it is arranged in the inside of universal joint exterior part) within the scope of this invention, can be favourable equally.Such stopping element for constructing safety backstop especially to construct discretely with universal joint exterior part at this and inserts in universal joint exterior part.Such as can use plate inserts (Blecheinleger), it provides safety backstop according to the present invention for tripod joint.Therefore the system existed of tripod joint can also be reequiped in a particularly simple way, because do not need the mechanically deformation of universal joint exterior part.Manufacture cost also reduces, because need not disturb existing processing method, but can continue application standard method.Such stopping element especially fixes about the position of its local in the inside of universal joint exterior part.Thus there such as can adhesively, screw ground, riveted joint ground or by occlusion kayser connect fix.
When in tripod joint according to the present invention, cage has the first stop surface and case has stop surface associated with it that (it is arranged like this, thus determine first and second end positions of cage relative to case thus) time, be favourable equally.In other words, the rolling element of cage and case self, i.e. tripod joint itself is used as the definition of end position and thus therefore as the definition possibility to standard path of travel.Therefore end position limits independent of universal joint exterior part.Especially, in such form of implementation, cage is dangerous relative to the slippage (Durchrutschen) of case, because do not arrange additional backstop completely within universal joint exterior part.Correspondingly, arrange safety backstop cause in mode according to the present invention, in the dynamic motion conditions of height, the risk of case distortion is reduced.
When universal joint exterior part is configured to tank shape and has bottom wall and at least one side wall surface within the scope of this invention, can be favourable equally.Tank shape means at this, and universal joint exterior part is such as configured to hollow cylinder, and it utilizes bottom wall to close on side.But, certainly also can consider more complicated cross-sectional geometry, especially for the cross-sectional geometry of cross section based on the star of three wedge angles within the scope of this invention.Side wall surface and bottom wall are at this especially at an angle to each other, particularly preferably (+/-10 °) roughly at a right angle.
In tripod joint according to the present invention, being furnished with at least one safety backstop like this when making it at least stop cage to contact with the bottom wall of universal joint exterior part, can be favourable equally.Because bottom wall is the wall be on the direct direction of the moving direction of rolling element of universal joint exterior part, the contact of cage and bottom wall is by relevant with to the maximum infringement of cage.Relate to head-on crash (Frontalcrash) at this, it will be attended by maximum mechanical influence.Namely this advantage is brought, namely by the most risky situation being avoided according to safety backstop of the present invention according to embodiment of the present invention.

Embodiment
Figure 1 illustrates the form of implementation according to tripod joint 100 of the present invention.It has universal joint exterior part 120 and tripod star 110.This tripod star 110 is for be delivered to moment of torsion tripod star 110 from universal joint exterior part 120 and to make the dislocation that is angled and that be directed upwards towards in the side of axis of universal joint exterior part 120 and tripod star 110 become possibility simultaneously.Be provided with three rolling elements 10, it is arranged around tripod star 110 with star for this reason.With schematic cross section, the cut-away section through in rolling element 10 is shown in FIG.The each of rolling element 10 has receiving bore 30, and the axle journal 112 of tripod star 110 is bearing in wherein.The dislocation of angle can be balanced in like fashion.In addition case 20 and cage 50 are provided with for each rolling element 10.Rolling element 40 in the form of balls in this form of implementation is fixed with in cage 50.These balls, i.e. rolling element 40 are supported between the case 20 of rolling element 10 and the working surface 122 of universal joint exterior part 120.The relative movement of the type with translation between rolling element 10 and universal joint exterior part 120 is made to become possibility in like fashion.In addition the relative movement between case 20 and cage 50 can be realized.The flexible relative movement between case 20 and universal joint exterior part 120 obtained on cage 50 can be said in like fashion.
In Fig. 2 a and 2b, describe the form of implementation according to tripod joint 100 of the present invention in detail, wherein, set forth the working principle of protection.The rolling element 10 according to tripod joint 100 of the present invention is shown in fig. 2 a with schematic cross section.In this form of implementation, not only cage 50 but also case 20 have stop surface 22 and 52, which defines two end position K1 and K2 of cage 50 in the inside of universal joint exterior part 120.At this, show the position of cage 50 in the K1 of first terminal position in fig. 2 a and show the position of cage 50 in the second end position K2 in figure 2b.The normal path of travel of rolling element 10 and therefore cage 50 is between these two end position K1 and K2.As can be identified from Fig. 2 a equally, between first terminal position K1 and safety backstop 70, there is spacing.This means, cage 50 between two end position K1 and K2 during proper motion safety backstop 70 do not contact with cage 50.
The safety backstop 70 of this form of implementation is configured to jut 70a, and it is realized by the outside impression from universal joint exterior part 120.By this mechanically deformation, in the inside of universal joint exterior part 120, produce jut, it is geometrically constructing like this, makes it prevention cage 50 be exceeded safety backstop 70 and continues motion.
Following reference drawing 2a and 2b elaborates the working principle according to safety backstop 70 of the present invention.If perform high dynamic motion when cage 50 moves between two end position K1 and K2, then can occur, perform the relative movement between cage 50 and case 20 in an undesired manner.Less desirable relative movement is like this motion being occurred (hinausgehen) by the rolling of rolling element 40.This less desirable motion also can be called as the slippage of case 20 relative to cage 50.Such slippage causes, such as, exceed this first terminal position K1 at cage 50 when the side of first terminal position K1 moves upward from the second end position K2.In other words, after such height moves dynamically, cage 50 leaves predetermined normal path of travel.As long as cage 50 can be avoided to collide in the sidewall of universal joint exterior part 120 one, especially bottom wall (as it forms the right closure (Abschluss) of universal joint exterior part 120 in fig. 2 a) place, this is no problem.Realize this in mode according to the present invention by safety backstop 70 to avoid.If namely after slippage in an undesired manner, cage 50 motion exceedes first terminal position K1, then this motion only can realize in the mode such as limiting it with the safety backstop 70 of the form of jut 70a.The motion exceeding safety backstop 70 is impossible.According to the present invention, avoid the mechanically deformation of the wall of cage 50 and universal joint exterior part 120, the contact especially between bottom wall and cage 50 thus in like fashion.
Show the form of implementation that two of safety backstop 70 are alternative in figures 3 and 4.Safety backstop 70 is embodied as groove 70b in figure 3 thus.Cage 50 has guiding projection 58, and it schematically shows in figure 3 and is such as configured to impression and the corresponding jut on the relative side of the contact pin at cage 50.This guiding projection 58 to join in groove 70b and causes desired stop.Also can pick out from Fig. 3, groove 70b only must extend in the region needing safety backstop 70.On the direction of the second end position K2, namely on left side, do not need such groove in figure 3, because be impossible by cage 50 and the contact of the wall of universal joint exterior part 120 here.For the purpose of clear, remove case 20 in figure 3, make to pick out groove 70b and corresponding guiding projection 58 better.
Another form of implementation according to tripod joint 100 of the present invention shown in Figure 4.In this form of implementation, safety backstop 70 is configured to stopping element 70c.As can be picked out, stopping element 70c is the component be separated with universal joint exterior part 120.It can be arranged in the part area place in the inside of universal joint exterior part 120, but also can arrange therein around the periphery of universal joint exterior part 120.At this, stopping element especially can adhesively, riveted joint ground, screw ground or by occlusion kayser connect be connected with universal joint exterior part 120.Stopping element is also configured in universal joint exterior part 120 place by forming technique.
Certainly, form of implementation discussed above only illustrates the present invention in the scope of example.Certainly, as long as each feature of each embodiment technically rationally also freely mutually can be combined, and scope of the present invention is not left.
