Description
Technical field
The present invention relates to a kind of tripod universal joint (Tripodegelenk) for transmitting torque between the axle of each other two rotations of angular misalignment.
Background technique
Be known on the tripod universal joint principle and have universal joint exterior part (Gelenkau enteil) and three rolling elements (Rollelement) that it can move with respect to the universal joint exterior part.These rolling elements be installed in the inside of universal joint exterior part and can its axially on the dislocation of two axles of translation ground balance.In addition, each rolling element has the receiving bore for bearing journal (Zapfen).This axle journal is the part of driven shaft, and driven shaft can be connected with each rolling element in this mode.May make at driven shaft with angular misalignment between the axle that the universal joint exterior part is connected via axle journal becomes possibility.In other words, known tripod universal joint is used for and making simultaneously in the moment of torsion transmission between these two axles along the angular misalignment of two axles of its axis balance and movement becomes possibility.Be known that also rolling element is provided with backstop, its will between rolling element and the universal joint exterior part, especially be restricted on the path of travel at the cage (Kaefig) of rolling element and the relative movement between the universal joint exterior part.Correspondingly, such backstop is implemented in known manner, in order to fix the first and second end positions.Two end positions that are used for normal operation are used for this, and rolling element does not leave the inside of universal joint exterior part on the one hand, and the motion of rolling element also is limited in the inside of universal joint exterior part on the other hand.
Yet, in the dynamic motion conditions of height, can cause, the relative movement between the case of cage and rolling element occurs in the mode of not expecting.In other words, this means, for the strong especially or especially fast motion between rolling element and universal joint exterior part, the relative movement that between the case of cage and rolling element, may occur not expect and can not estimate.In this mode, also mobile for the preposition of the corresponding end position of normal path of travel.According to this direction that moves, this can cause, and rolling element now can be mobile outside predetermined path of travel with respect to the universal joint exterior part.This especially can cause, and rolling element is in the wall of universal joint exterior part in the time of in sailing the universal joint exterior part into, especially bottom wall contacts.Such contact can cause, and the other element of cage, case or rolling element is because this contact is damaged.Especially in the universal joint exterior part that forges and in the inclination of the corresponding standard in universal joint exterior part place, this can cause, the rolling bearing zone of cage curve inwardly and cause thus the friction that improves or cause rolling element be obstructed fully functional.In other words, in the result of the dynamic motion conditions of height, the such relative movement of not expecting between cage and case can cause, and the parts of tripod universal joint or tripod universal joint can not use on the whole.
Summary of the invention
The objective of the invention is to eliminate the above-mentioned problem of known tripod universal joint.In particular, the purpose of this invention is to provide a kind of tripod universal joint with universal joint exterior part and rolling element, it can tackle (abfangen) in functional infringement of cage and the corresponding relative movement between the case and high dynamic motion and the prevention tripod universal joint of rolling element.
Realize above purpose by the tripod universal joint with the feature of independent claims 1.Other feature of the present invention and details draw from dependent claims, specification and accompanying drawing.
Tripod universal joint according to the present invention has universal joint exterior part and at least one rolling element.In particular, use three rolling elements in tripod universal joint according to the present invention, it distributes with star.This at least one rolling element has cage and case (its band is useful on the receiving bore of the axle journal of supporting tripod star (Tripodestern)).Via this axle journal possible be that the tripod star can be angled with respect to the axle that is connected with the universal joint exterior part with the axle that is connected therewith.In addition, there is the rolling element that is associated with case of locating for the guide rail respect to one another (Laufbahn) that case is supported on the 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 the motion that avoids not expecting by cage, thereby it makes dual rolling become possibility.Rolling element rolls at the case of rolling element self on the guide rail of universal joint exterior part and on the other hand on the one hand thus.Therefore can say to produce case via cage telescopic (teleskopartig) motion to the rolling element, and vice versa.
Tripod universal 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, so that stop cage to contact with the wall of universal joint exterior part when cage moves with respect to the universal joint exterior part.Safety backstop namely is independent of rolling element, especially is independent of cage and the case of rolling element.Safety backstop is for example in the inside of universal joint exterior part and preferably be independent of the normal path of travel of rolling element between two end positions.Preferably, only when high dynamic motion, the i.e. relative movement of not expecting between the case of cage and rolling element occurring, safety backstop is just intervened.Geometrical arrangements scheme by safety backstop guarantees so, and rolling element, especially its cage only can continue motion in this mode, although it has left normal path of travel, does not however contact with the wall of universal joint exterior part.Its wall that especially depends on is the bottom wall of universal joint exterior part at this.For this reason, safety backstop for example is installed in its inside at the side wall surface place of universal joint exterior part.
Safety backstop not only can be constructed the part of wall-forming in mode according to the present invention, and can construct discretely with this wall.In addition, except protective function, also can satisfy again correction function (Rekalibrierungsfunktion) by this safety backstop.If produce the relative movement between cage and the rolling element in tripod universal joint according to the present invention, then path of travel moves.On this zone, it is allowing aspect to be avoided contact of cage and universal joint exterior part safety backstop with this mobile restriction.Correspondingly, carry out again calibration by this restriction by means of safety backstop, that is to say, force relative movement conversely between cage and case.In other words, cage and case move with the relative movement that produces owing to high dynamic motion before again by cage being stopped at the safety backstop place on the contrary, near initial position.Not only can stop the mechanically deformation of cage in this mode, and in addition again calibration also be possible, thereby also can maintenance application in the situation that not have additional maintenance or repair cost according to tripod universal joint of the present invention after the dynamic motion of height.
The stop surface of safety backstop correspondingly is configured in the cage or its place.In particular, cage also has and is configured to and the synergistic stop surface of safety backstop.Be configured in accordingly this especially on how much and/or prepare like this on the zone, so that can be implemented in safety backstop and cage, contacting between its stop surface especially.Safety backstop in tripod universal joint according to the present invention preferably is arranged on the side wall surface place of universal joint exterior part at this.
In scope of the present invention when in tripod universal joint according to the present invention like this design cage so that it can move with respect to the universal joint exterior part between at least two end positions the time, can be favourable.This means that limit 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 zone between these two end positions.The layout of this safety backstop is namely outside the standard path of travel.In other words this means that cage can move in that standard is in service, and does not contact with safety backstop between these two end positions.Safety backstop does not namely in servicely engage with the cage of rolling element normal, thereby does not produce the wearing and tearing of safety backstop and cage at all or contact.When cage left the standard path of travel between two end positions and will exist cage to impinge upon the risk at wall place of universal joint exterior part, safety backstop just worked at its protective function.Namely the safety backstop normal in service at the tripod universal joint is not restrictive.Especially can trace back to the existing structure of tripod universal joint at this, thereby also can use this safety backstop as the remodeling function for so existing tripod universal joint.
When at least one safety backstop of in tripod universal joint according to the present invention, being configured with the form of the jut on the wall of case exterior part, can be favourable equally.At this, this jut especially is configured in the side wall surface place of universal joint exterior part.This jut is preferably constructed like this, so that enter when being in wall, especially in the danger that contacts of the bottom wall of universal joint exterior part when cage, this jut can and contact with cage on how much partly at least piecemeal.The safety backstop of such structure especially cost suits and can make simply.The manufacturing feasibility with at the safety backstop of the form of the jut on the wall of universal joint exterior part like this is the so-called impression section (Pr gewarze) on this wall.At this, especially produce such impression section by the impression on the outside of universal joint exterior part.Cause the also distortion on the inboard of universal joint exterior part at the such impression on the outside of universal joint exterior part, thereby be configured with corresponding jut at the side wall surface of universal joint exterior part, it is used as safety backstop according to the present invention.From the outside effect brings this advantage, namely also can further reduce manufacture cost.
When at least one safety backstop of in tripod universal joint according to the present invention, being configured with the form of groove (utilizing it to guide at least partly at least a portion of cage), can be favourable equally.This groove in the inside of universal joint exterior part especially is configured in the material of universal joint exterior part.Preferably, be provided with and enter inclined-plane (Einlaufschr ge), make in other words with the rolling element of cage easily in the insertion groove in this groove so that cage can easily enter.This guiding needn't cover the whole standard operation area of rolling element forcibly at this, but especially only is configured in its end regions about the end position of the key of standard path of travel.In other words, entering after cage is only leaving the standard path of travel in the time of can satisfying protective function by groove in the groove and in mode according to the present invention, is enough.
When cage in tripod universal joint according to the present invention has at least one guiding projection (it joins in the groove and is configured to stop at least one safety backstop place of groove), it is another advantage.Such guiding projection for example can be configured to the protuberance of nose shape, and it fully or at least partly is guided through groove.In particular, guiding projection angularly, especially stretches out from cage about the moving direction of cage with meeting at right angles like this.Such form of implementation make cage and universal joint exterior part simplification be constructed to possibility so that other functional adjustment of the rolling element that groove and guiding projection can be separate keep in cage with by cage.In addition, provide the especially reliably form of implementation of safety backstop by the guiding of guiding projection in groove.
When in scope of the present invention, when being configured with at least one safety backstop, can being favourable by stopping element (it is arranged in the inside of universal joint exterior part) equally.The universal joint exterior part is especially constructed and insert to the such stopping element that is used for the structure safety backstop discretely at this with the universal joint exterior part.For example can use plate inserts (Blecheinleger), it provides safety backstop according to the present invention for the tripod universal joint.Therefore also can reequip the system that has existed of tripod universal joint in simple especially mode, because do not need the mechanically deformation of universal joint exterior part.Manufacture cost also reduces, because needn't disturb existing processing method, but can continue the application standard method.Such stopping element especially fixes about the position of its part in the inside of universal joint exterior part.Thus there for example can be adhesively, screw ground, riveted joint ground or connect by the interlock kayser and fix.
When cage in tripod universal joint according to the present invention has the first stop surface and case when having stop surface associated with it (it arranges like this, thereby determines that thus cage is with respect to the first and second end positions of case), be favourable equally.In other words, cage and case self, be that the rolling element of tripod universal joint itself is used as thus to the definition of end position and therefore as the definition possibility to the standard path of travel.Therefore end position is independent of the universal joint exterior part and limits.Especially in such form of implementation, cage is dangerous with respect to the slippage (Durchrutschen) of case, because additional backstop is not set within the universal joint exterior part fully.Correspondingly, in mode according to the present invention safety backstop is set and causes, the risk of case distortion is reduced in the dynamic motion conditions of height.
When universal joint exterior part in scope of the present invention is configured to tank shape and has bottom wall and during at least one side wall surface, can be favourable equally.Tank shape means that at this universal joint exterior part for example is configured to hollow cylinder, and it utilizes bottom wall to seal in a side.Yet, in scope of the present invention, certainly also can consider more complicated cross-sectional geometry, especially for the cross-sectional geometry of cross section take the star of three wedge angles as the basis.Side wall surface and bottom wall this especially at an angle to each other, (+/-10 °) particularly preferably roughly meet at right angles.
It in tripod universal joint according to the present invention, is furnished with like this at least one safety backstop so that when stoping at least cage to contact with the bottom wall of universal joint exterior part, can be favourable equally.Because bottom wall is the wall on the direct direction of the moving direction that is in rolling element of universal joint exterior part, the contact of cage and bottom wall will be relevant with the maximum infringement to cage.Relate to head-on crash (Frontalcrash) at this, it will be attended by maximum mechanical influence.Namely bring this advantage according to embodiment of the present invention, namely can avoid the most risky situation by safety backstop according to the present invention.

Embodiment
Figure 1 illustrates the form of implementation according to tripod universal joint 100 of the present invention.It has universal joint exterior part 120 and tripod star 110.This tripod star 110 is used for moment of torsion is delivered on the tripod star 110 and makes simultaneously universal joint exterior part 120 and the dislocation angled and that point in the direction of axis of tripod star 110 becomes possibility from universal joint exterior part 120.Be provided with three rolling elements 10, it is arranged around tripod star 110 with star for this reason.In Fig. 1, with schematic cross section one the cut-away section that passes in the rolling element 10 is shown.Each of rolling element 10 has receiving bore 30, and the axle journal 112 of tripod star 110 is bearing in wherein.But the dislocation with this mode balance angle.Be provided with case 20 and cage 50 for each rolling element 10 in addition.In cage 50, be fixed with in this form of implementation the rolling element 40 with the form of ball.These balls, be that rolling element 40 is supported between the working surface 122 of the case 20 of rolling element 10 and universal joint exterior part 120.Make between rolling element 10 and universal joint exterior part 120 relative movement with the type of the translation possibility that becomes in this mode.Can realize in addition the relative movement between case 20 and the cage 50.Can say that in this mode acquisition is in the case 20 on the cage 50 and the flexible relative movement between the universal joint exterior part 120.
In Fig. 2 a and 2b, describe the form of implementation according to tripod universal joint 100 of the present invention in detail, wherein, set forth the working principle of protection.In Fig. 2 a, show rolling element 10 according to tripod universal joint 100 of the present invention with schematic cross section.In this form of implementation, not only cage 50 but also case 20 have stop surface 22 and 52, and it defines two end position K1 and the K2 of cage 50 in the inside of universal joint exterior part 120.At this, in Fig. 2 a, illustrated cage 50 in the K1 of first terminal position the position and the position of cage 50 in the second end position K2 has been shown in Fig. 2 b.Rolling element 10 and therefore the normal path of travel of cage 50 between these two end position K1 and K2.As can from identifying Fig. 2 a, between first terminal position K1 and safety backstop 70, having spacing equally.This means, cage 50 between two end position K1 and the 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 impresses to realize by the outside from universal joint exterior part 120.By this mechanically deformation, in the inside of universal joint exterior part 120, produce jut, it is constructed on how much like this, continues motion so that it will stop cage 50 to surpass safety backstop 70.
Next elaborate working principle according to safety backstop 70 of the present invention with reference to figure 2a and 2b.If when cage 50 moves, carry out high dynamic motion between two end position K1 and K2, then can occur, carry out relative movement between cage 50 and case 20 in the mode of not expecting.The relative movement of not expecting like this is the motion that occurs (hinausgehen) by the rolling of rolling element 40.This motion of not expecting also can be called as case 20 with respect to the slippage of cage 50.Such slippage causes, and for example surpasses this first terminal position K1 at cage 50 from the second end position K2 when the direction of first terminal position K1 is moved.In other words, after so high dynamic motion, cage 50 leaves predetermined normal path of travel.As long as can avoid in the sidewall of universal joint exterior part 120 one of cage 50 collision, especially bottom wall (forming the right closure (Abschluss) of universal joint exterior part 120 such as it in Fig. 2 a) is located, this is no problem.This is avoided by safety backstop 70 realizations in mode according to the present invention.If namely surpassing first terminal position K1 with 50 motions of cage after the mode slippage do not expected, then this motion only can realize in the mode that limits it such as the safety backstop 70 with the form of jut 70a.The motion that surpasses safety backstop 70 is impossible.According to the present invention, avoid cage 50 and the wall of universal joint exterior part 120, contacting and the thus mechanically deformation of cage 50 between the bottom wall especially in this mode.
Two alternative forms of implementation of safety backstop 70 have been shown in Fig. 3 and 4.Safety backstop 70 is embodied as groove 70b in Fig. 3 thus.Cage 50 has guiding projection 58, and it is schematically illustrated and for example be configured to impress and corresponding jut on the relative side of the contact pin of cage 50 in Fig. 3.This guiding projection 58 joins among the groove 70b and causes desired stop.Also can pick out from Fig. 3, groove 70b only must extend in the zone that needs safety backstop 70.On the direction of the second end position K2, namely in Fig. 3, on the left side, do not need such groove, because the contacting of wall here by cage 50 and universal joint exterior part 120 is impossible.For the purpose of clear, in Fig. 3, remove case 20, so that can pick out better groove 70b and corresponding guiding projection 58.
Another form of implementation according to tripod universal 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 picking out, stopping element 70c is the member that separates with universal joint exterior part 120.It can be arranged in the place, part area in the inside of universal joint exterior part 120, but also can be arranged in around the periphery of universal joint exterior part 120 in its inside.At this, stopping element especially can be adhesively, riveted joint ground, screw ground or connect by the interlock kayser and be connected with universal joint exterior part 120.Stopping element also can be configured in universal joint exterior part 120 places by forming technique.
Certainly, form of implementation discussed above only illustrates the present invention in the scope of example.Certainly, as long as technically rationally can freely mutually make up each feature of each embodiment, and do not leave scope of the present invention yet.
