Description

The invention relates to a shaft-hub connection for a drive train of a motor vehicle for connecting a dual mass flywheel secondary flange (ZMS Sekundärflansches) to a torque receiving part, with an inner toothing having dent, wherein in the internal teeth external teeth of a hub is fitted, wherein between the Hub and the dent on both components a radially biased spring plate with a closed cross-section is inserted so that the preferably metallic, eg. Steel spring plate, on the one hand with a support surface supported on a portion of the hub and on the other hand with a support surface radially opposite support surface so supported on a portion of the shaft that the friction on the support surface and the support surface for each counterpart partner from shaft or hub inhibiting acts on a relative rotation of the hub to the shaft.

Solutions for the integration and connection of secondary flanges of a dual-mass flywheel to a torque receiving part in the manner of a shaft of a clutch or a transmission are already known from the prior art.

Numerous torque transmission devices are already known from the prior art. For example, the DE 10 2005 037 514 A1 a torque transmission device in the drive train of a motor vehicle for torque transmission between a drive unit, in particular an internal combustion engine, with an output shaft, in particular a crankshaft, and a transmission with at least two transmission input shafts which are each rotatably connected to a clutch disc having friction linings, wherein between the friction linings of a clutch disc and the friction linings of the other clutch disc an intermediate pressure plate is arranged, which is non-rotatably connected to the output shaft of the drive unit, wherein the friction linings of the clutch discs between the intermediate pressure plate and the pressure plates are arranged by means of an actuator in relation to the transmission input shafts, relative to the axial direction to the intermediate pressure plate are movable to pinch the friction linings between the intermediate pressure plate and the pressure plates. In that earlier patent publication, a plate spring between a coupling housing part and an output part is used.

From the prior art, namely the DE 10 2015 219 251 A1 is also a shaft-hub connection in connection with clutches, in particular double clutches disclosed, which is in this field, the invention. Thus, the earlier published patent publication discloses a hub for a shaft-hub connection, in particular for a drive train of a motor vehicle, with an inner profile, in particular an internal toothing, for positive cooperation with an outer profile, in particular an external toothing, a shaft rotatable about a rotation axis, and a A receiving space for receiving a clamping means for reducing a clearance between the inner profile and the outer profile, wherein the inner profile is partially broken in the receiving space, wherein the receiving space at least one location radially inner hub inside arranged with a radially outer hub outside by at least one in the axial direction between connecting the first hub end and a second hub end disposed continuously to improve the shaft-hub connection structurally and / or functionally by receiving the clamping means. That prior disclosure employs a biasing means having tensioning portions that contact a hub with the radially outer side of an outer profile of a shaft portion during insertion into a receiving space / groove. On the radial outer side of the hub, a support ring is inserted.

A shaft-hub connection for transmitting torque in a drive train of a motor vehicle, a method for mounting such a connection and a method for operating the drive train is in DE 10 2014 212 844 A1 disclosed. There, a shaft-hub connection for torque transmission in a drive train of a motor vehicle is presented, in particular between a torsional vibration damper for damping rotational irregularities of a motor shaft of an automotive engine and a clutch for coupling the motor shaft with a transmission input shaft of a motor vehicle transmission provided with an external toothing for a spline toothing Shaft, an internal toothing for the spline having hub and a voltage applied to the shaft and the hub spring element to provide a torque transmission between the shaft and the hub on the spline past, with a maximum torque on the spring element transferable torque M _R by a frictional engagement of the spring element is limited to the shaft and / or the hub. By the spring element can be achieved with correspondingly low torques below M _R , especially in idling mode of the motor vehicle engine, a frictional rotationally fixed connection of the shaft with the hub, so that a possible by a backlash of the spline mutual engagement of the tooth flanks of the internal teeth and the external teeth is avoided , which allows a powertrain with low noise emissions. There are several Embodiments presented, among other things, a spring element is presented as a ring body, wherein the ring body is designed in particular as a circumferentially closed polygon ring, which deviates from a strictly hollow cylindrical shape.

The subject invention thus relates to an axial spline between a ZMS secondary flange and an input hub to a clutch or a transmission. While it is already set from the prior art to the introduction of an additional friction between the two sides of a toothing by sheet metal components, it has been found that, for example, during prolonged operation, the noise occurs again. This disadvantage is also evident in certain operating conditions with flat, closed Blechpolygonringen between the hub and the shaft, in particular arranged on the side on which the toothing is not formed. Even open, springy wire rings between hubs and shafts are not sufficient solution in isolation. They are arranged on the toothed side and act on the one toothing. Although these three already known solutions have disadvantages, but are much cheaper than the hitherto customary choice of custom-fit Verzahnungsherstellens. Up to those three older inventions it was customary to avoid the rattling noises in the toothing caused by engine vibrations due to precisely fitting toothings. The otherwise always present "certain" play in the gearing can be reduced or even eliminated with such precisely fitting gearing, but unfortunately is very cost-intensive.

It is therefore the object of the present invention to optimize a shaft-hub connection so that the costs are kept low, but the noise emission is reduced or even eliminated, and also permanently. In particular, a migration of the noise reduction component should be prevented.

This object is achieved in a generic shaft-hub connection according to the invention that at least one predominantly radially outwardly facing securing hook is formed on the spring plate. It should be noted that under a spring plate is not necessarily only a flat component with spring properties to understand, but the spring plate may well have a round or elliptical cross-section in the sense of a wire.

One could also say that the invention relates to a polygon sheet with one or more optional threading tabs, retaining tabs and spacer tabs, wherein the retaining tab or tabs are present on the side of the teeth of the shaft-hub connection. The spring steel sheet can also be referred to as a polygon sheet or polygon sheet metal. The spring plate / polygon sheet can thus be present in the toothing engagement of the internal teeth with the external teeth or directly offset axially thereto. Alternatively, it is also possible to use a polygon ring in a groove of a transmission input shaft, which provides the internal toothing. The internal teeth then interact with a ZMS hub with their external teeth.

This alternative solution thus relates to a shaft-hub connection for a drive train of a motor vehicle, for connecting a ZMS secondary flange to a torque receiving part, with an internal toothing having a shaft, wherein in the internal teeth external teeth of a hub is fitted, wherein between the hub and the shaft on both components a radially biased spring plate with open or closed cross-section is inserted so that the spring plate, in particular a metallic or steely formed spring plate on the one hand with a support surface supported on a portion of the hub and on the other hand with one of the support surface radially opposite Supporting surface so supported on a portion of the shaft that the friction on the support surface and the support surface to the respective counterpart (from shaft or hub) inhibiting acts on a relative rotation of the hub to the shaft. The inventive solution in development of this generic device then consists in that made of wire material, such as round cross-section spring plate, in a groove in that the internal toothing forming component is inserted so that it contacts the external teeth.

Advantageous embodiments of the invention are claimed in the subclaims and are described below.

Thus, it is advantageous if the safety hook is formed as, for example, in the development rectangular retaining tab, namely as an integral / one-piece / einmaterialiger part of a main body of the spring plate. In this way, cost-effective and time-efficient working non-cutting forming processes, such as punching and bending processes can be used.

In operation, it has been found to be particularly advantageous if the spring plate has a polygonal cross-section, such as in the manner of a four-, six- or octagon, for example. With rounded corners, has. The production of the spring plate is in this case also particularly simple and possible in high numbers of cycles.

It is also useful if the safety hook as a nearly or exactly orthogonal formed by the main body projecting / bent retaining tab. In the case of orthogonality, it is advantageous to provide a flat abutment of the retaining lug on the face-shaped hub section made in the manner of a solid shaft by the ZMS secondary flange.

It has also proven useful when a plurality of retaining tabs, such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or more, distributed over the circumference, preferably evenly distributed, are present. Even with two retaining tabs, the spring plate / polygon ring is held sufficiently tipping safe, whereas in three retaining tabs this condition is improved. Particularly preferred is the presence of four retaining tabs, since then tilting is effectively excluded.

An advantageous embodiment is also characterized in that protrudes at a front end of the main body, such as the gear or motor-side distal end of the main body, the safety hook. If the safety hook is on the gearbox side end, it can be hooked to a rear grip or engagement point on the inside of the (hollow) shaft, whereas a fixing to a distal end of the (hollow / gearbox) input shaft in the presence of the safety hook on motor-side distal end is beneficial.

So it has proven, for example, when the safety hook on the shaft position fixes attacking.

It is preferred if the safety hook engages in a groove on the inside of the (hollow) shaft (on / behind) or abuts against a front end of the shaft, for example in the region of a collar, as embracing or attacking the local distal end ,

In particular, in a further development of said alternative, it is advantageous if the contact between the outer toothing and formed as a polygon ring spring plate on the radial outer side of the outer toothing occurs.

It is advantageous if a groove bottom of the groove is provided by a one-piece / integral part of the shaft.

An advantageous embodiment is further developed in that the groove has two groove walls or open on one side.

The assembly is simplified if the spring plate is arranged in the region of the internal toothing and the external toothing or axially offset thereto. It should also be pointed out that the shaft provides a mating surface for abutment with the support surface or preferably the support surface and the hub provides a complementary surface for abutment with the support surface or preferably the support surface. In this way, frictional forces between the spring plate and the shaft on the one hand and frictional forces between the spring plate and the hub on the other hand can produce, which counteract damping of unwanted rotation of the hub relative to the shaft and thus act noise-preventing.

The structure is simplified when the support surface is a radially outer surface of the spring plate and the support surface is a radially inner surface of the spring plate or vice versa.

Furthermore, it has proven useful if the securing tab comes into abutment with a preferably facing the motor end face of the shaft and is formed. If the spring plate is arranged approximately in extension of an imaginary axially extending separation plane through the location of the positive connection between the external toothing and the internal toothing, so a compact design can be achieved.

Finally, the invention also relates to a drive train with a ZMS secondary flange and a clutch transmission input shaft, which forms a shaft-hub connection of the type according to the invention.

In other words, a spline toothing has been used to avoid gear rattle. This is too expensive, which is why alternative solutions, such as those of DE 10 2005 037 514 A1 , those of DE 10 2015 219 251 A1 and those of DE 10 2014 212 844 A1 Have advantages. In particular, those on the type of Axialbügeln have advantages, but are not yet sufficiently optimized. It is therefore necessary to turn off the previous disadvantages.

Although dual-clutch / hybrid / CVT dampers, which begin in the region of the connection between the damper and the transmission input, are known, but it is common to avoid tooth splines. The standard solution is so far a damper hub with cleared teeth and a correspondingly toothed transmission input shaft or an externally toothed damper hub on an internally toothed transmission input shaft. Here, however, the invention begins and relies on a frictional connection for realizing a friction solution and / or a form fit for realizing a bracing solution and / or an adhesive bond for realizing an adhesive solution. For the application of externally toothed damper hubs on internally toothed transmission input shafts, these are thus compared the prior art and the consequent interlocking play optimized under the otherwise occurring causing an acoustic impairment.

For example, the traction / friction solution is based on an axial brace. The solution is in addition to the known parts such as transmission input shaft and ZMS hub and that Axialspange. The Axialspange is a bent wire which is arranged perpendicular to the joining direction in the transmission input shaft. During joining, the wire is pushed / pushed radially outward, which results in a return force on actuation. In operation, a friction torque is thereby generated, which prevents or reduces the gearing rattling.

Another adhesion / friction solution has been found in the insertion of a polygon sheet. This polygon sheet is designed in one piece. The solution is then in addition to the known parts such as transmission input shaft and ZMS hub and a polygon sheet. The polygon sheet is a curved, closed sheet metal. The polygon sheet is arranged perpendicular to the joining direction in the transmission input shaft. For axial securing this polygon sheet has on the circumference securing hooks which engage in a securing groove in the transmission input shaft. When joining the sheet is pressed / pushed locally outward. By pressing it comes to a restoring force. In operation, a friction torque is thereby generated, which prevents or reduces the gearing rattling.

Another polygon sheet metal ring with a closed contour, for example. Using a latch, this is alternatively used. The solution is then in addition to the known parts, such as transmission input shaft and ZMS hub, and a polygon sheet metal ring. The polygon sheet metal ring can be made closed with a notch. A positive connection is realized at the ends. For axial securing the polygon sheet metal ring also has safety hooks on the circumference. When joining the sheet metal ring is locally pushed outward / operated. By pressing it comes to a restoring force. In operation, a friction torque is thereby generated, which prevents or reduces the gearing rattling.

Alternatively, a polygon ring can be used. The solution is then in addition to those known parts such as transmission input shaft and ZMS hub, also made of a polygonal wire ring. The polygon wire ring is a bent wire that is perpendicular to the joining direction in the transmission input shaft. For axial securing this is inserted in a groove in the transmission input shaft. When joining the wire is actuated radially outward. By pressing it comes to a restoring force. In operation, a friction torque is thereby generated, which prevents or reduces the gearing rattling.

In addition, a form-fitting / bracing solution is to be seen that relies on a split shaft. The solution is then in addition to the known parts such as transmission input shaft and ZMS hub, and a toothed disc. The toothed disc is mounted twisted in the circumferential direction to the hub teeth. Hub and disc are fixed by an elastomer. The connection is achieved by vulcanization. To facilitate assembly, the toothing of the ZMS hub is provided with a threading bevel. When joining the disc is rotated to the hub. Both gears are then in flight.

In addition, an adhesive / bonding solution can be used, wherein a securing agent / bonding adhesive is applied to the toothed surface of the hub and / or the shaft. Especially in the context of dual mass flywheels (DMF) show great advantages of the invention in practice. Especially in the area of an axial spline between the ZMS secondary flange and an input hub of the clutch or gearbox, the desired application area can be seen. A play in the internal teeth relative to the external teeth due to engine vibrations, which leads to rattling noises is prevented. The use of precise gears can be dispensed with. The always occurring "certain" game is accepted and the otherwise occurring negative consequences are eliminated or at least reduced.
