Description

Rotating assembly and torque transmission device for a clutch and/or damper device

Technical Field

The present invention relates to a rotating group for a clutch or damper device of a drive train of a vehicle, in particular of a motor vehicle. The invention further relates to a torque transmission device, in particular a clutch or damper device, for a drive train of a vehicle, in particular a motor vehicle.

Background

During operation, a crankshaft of a cyclically operating internal combustion engine of a motor vehicle exhibits overlapping rotational irregularities during the rotation of the crankshaft, wherein the pattern and/or frequency thereof varies with the rotational speed of the crankshaft. In contrast, severe rotational irregularities occur during operation of the motor vehicle when the torque of the internal combustion engine changes, for example, when the torque demand is changed by the driver of the motor vehicle. Furthermore, torsional vibrations are excited in the drive train of the motor vehicle by the combustion process in the internal combustion engine, in particular during traction operation.

In order to reduce rotational irregularities and/or torsional vibrations in the drive train, a torsional vibration damper, which optionally has a centrifugal force pendulum device, can be used, wherein the torsional vibration damper is able to substantially eliminate relatively severe rotational irregularities and the centrifugal force pendulum device is able to substantially eliminate substantially periodic torsional vibrations in the rotational speed range of the internal combustion engine. Torsional vibration dampers, which may also be referred to as torsional vibration dampers, can be used in particular as damper devices between an internal combustion engine and a conventional transmission or an automatic transmission of a motor vehicle.

Thus, torsional vibration dampers can be used, for example, on/in dual-mass converters, in converters or hydraulic torque converters or on/in clutch disks or friction disk carriers of friction clutches. The centrifugal force pendulum device is often a component of a torsional vibration damper, wherein the centrifugal force pendulum device can be assigned to a hydraulic torque converter of an automatic transmission, for example, a turbine or a turbine. Due to cost pressures, increased performance and/or the ever smaller installation space of the drive train of a motor vehicle, developers are increasingly concerned with this which, until now, has caused only a few or simply to be eliminated.

Such a problem range exists in the design of torsional vibration dampers having one or more damper stages for a small installation space. In the torsional vibration damper, a torque can be introduced into the side discs via the inner or outer disk carrier of the clutch, the intermediate element and the rivet connection. From the two side disks, which are often also designed as retainers, torque can be transmitted into the transmission input shaft via/in the energy store ((linear/arcuate) compression springs) and the hub flange of the torsional vibration damper. The side disks serve to hold and guide the energy accumulator, wherein the side disks are fixedly connected by means of a rivet connection or a welded connection.

In order to be able to introduce a torque into the torsional vibration damper, an intermediate component is present between the inner or outer disk carrier and the actual torsional vibration damper. That is, an additional riveted or welded connection with a large number of rivets is required between the inner or outer friction lining carrier and the side disk. Furthermore, a riveted connection with a large number of rivets is required between the side discs, wherein either special rivets or rivets and bushings are mainly used. Instead of rivet connections, which are relatively cost-intensive, it is of course also possible to use relatively expensive welded connections. Furthermore, the associated torsional vibration damper is simple to construct and is therefore inexpensive to maintain.

Disclosure of Invention

The object of the present invention is to provide an improved rotating assembly for a clutch or damper device of a drive train of a vehicle, in particular a motor vehicle, and a corresponding torque transmission device. The improved rotating assembly reduces the cost of manufacturing the damper assembly and/or the clutch. In addition, a damper arrangement and/or a clutch which can be provided in this way has a low axial and/or radial installation space requirement for efficient power transmission, for example in converters. Furthermore, it is to have a structure which is simple and compact in construction and easy to assemble and is furthermore cost-effective in terms of its manufacture, assembly, operation and/or maintenance.

The object of the invention is achieved by means of a rotating assembly for a clutch or damper device of a drive train of a vehicle, in particular a motor vehicle; and is realized by means of a torque transmission device, in particular a clutch or damper device, for a drive train of a vehicle, in particular a motor vehicle.

The rotary assembly according to the invention comprises at least one damper rotary component and a rotary component, preferably a clutch rotary component, in particular a friction lining carrier, on the damper input side or on the damper output side, wherein the damper rotary component is directly fixed in/on the rotary component or the friction lining carrier in a rotationally fixed manner in the circumferential direction of the rotary assembly. The torque transmission device according to the invention has a rotating assembly according to the invention. According to the invention, the at least one damper rotary component is fixed or fixed in/on the rotary component or the friction lining carrier in a rotationally fixed manner without one or more intermediate components. Here, the damper rotating member may be configured as a side disc, a counter disc, a flange, a support plate, a clutch rotating member, and/or a friction plate.

In one embodiment of the invention, the at least one damper rotary element is suspended centrally in or on the rotary element or the friction lining carrier by means of a toothing.

Furthermore, the side disk and/or the counter disk are centered by being fixed in a rotationally fixed manner to the hub and serve as an input element or output element for the damper device.

According to the invention, the damper rotary component can be fixed in/on the rotary component or the friction lining carrier indirectly or directly in the axial direction of the rotary component by means of a fixing ring, a wedge and/or a pin fixing. At least one spring or energy accumulator, in particular at least one disk spring, is arranged inside the rotary assembly between the components of the rotary assembly for reducing the play of the rotary assembly in the axial direction. Here, the springs can preferably be arranged between the fixed ring and the damper rotary member, between the flange and the side disc, between the damper rotary member and the side disc, and/or between the damper rotary member and the flange in the rotary assembly.

According to the invention, the two damper rotary components are held in/on the rotary component or the friction lining carrier in the axial direction of the rotary assembly with a mechanical pretension against each other.

The two damper rotary members can be two side discs of the rotary assembly, or the at least one damper rotary member can be configured as a side disc. According to the invention, the rotating assembly, which is essentially enlarged toward the damper device, can be at least between two side discs and/or the side discs can be attached to the input element or the output element of the damper device without a rivet or rivets.

In one embodiment of the invention, the rotary component or the friction lining carrier and the damper rotary component of the rotary assembly can be designed in such a way that the guiding of the damper rotary component in/on the rotary component or the friction lining carrier in the axial direction and/or in the circumferential direction can be achieved by means of the rotary component or the friction lining carrier. In addition, the mechanical forces in or from the rotary component can be received in the axial direction in the rotary component or in the friction lining carrier indirectly or directly via the side discs. The mechanical force is preferably a mechanical spring force, and the force comes from an energy store, preferably from a spring, in particular a disk spring.

The flange of the rotating assembly can be displaced in the axial direction and is fixed directly in/on the rotating component or the friction lining carrier in a rotationally fixed manner in the circumferential direction. A rotating component or a friction lining carrier can be used as a mechanical coupling element for the two side discs, wherein mechanical forces can be transmitted from one side disc to the other side disc (usually called counter disc) by means of the rotating component or the friction lining carrier. In addition, the two side disks can be mounted in/on the rotating component or the friction disk carrier in one axial direction or in two opposite axial directions indirectly or directly, wherein the two side disks are preferably fixed in/on the rotating component or the friction disk carrier in a rotationally fixed manner in the circumferential direction, preferably directly.

According to the invention, the rotary component or the friction disk carrier can be designed such that it receives an axial force inside or from the rotary component instead of rivets, wherein the rotary component or the friction disk carrier serves to center, position and/or support at least one side disk and/or flange of the rotary component. The rotary element or the friction lining carrier can be designed such that it can be coupled to an electric motor (electric machine), can be connected to the rotor of the electric motor, can be connected to a further clutch, or be designed as a rotor of the electric motor.

In an embodiment of the invention, the rotational damper member, the rotational member and/or the friction lining carrier can be constructed in one piece, in one piece of material, simply and/or in one piece. Furthermore, the rotating member may be configured as a cage, a coupling element or a clutch rotating member. Furthermore, the friction lining carrier can be designed as a friction lining holder or essentially as a ring or a tube. Furthermore, the friction lining carrier can be designed as an outer friction lining carrier or as an inner friction lining carrier. Preferably, the friction linings are configured as friction linings or clutch friction linings and/or the fastening part is configured as a rivet or weld.

In embodiments of the invention, the spring can be received in the rotating assembly on a radially inner radius of the rotating assembly. Furthermore, the mechanical pretension or the mechanical force in the axial direction can be a mechanical spring pretension or a mechanical spring force. Furthermore, the two side discs can be mounted in/on the rotary component or the friction lining carrier in opposite axial directions. Furthermore, a slide housing can be provided between the rotating element or the friction lining carrier and the energy accumulator of the rotating assembly. And furthermore, one side disc can have a toothing which fits into a second side disc or hub. According to the invention, the vibration damper arrangement is in particular designed as a torsional vibration damper arrangement.

Drawings

Fig. 1 to 8 of the drawings each show an embodiment of a first variant of the invention in a half-section through the center, cut out on both sides in the axial direction, of a torsional vibration damper associated with a multi-plate clutch with an assembly according to the invention, the damper rotary component of the assembly being directly fixed in a rotationally fixed manner in the circumferential direction of the assembly or being mounted in a rotary component of the multi-plate clutch, which is designed as an outer disk carrier. Furthermore, fig. 9 to 15 each show an embodiment of a second variant of the invention, also in a half-section of the center, cut out on both sides in the axial direction, of a torsional vibration damper associated with a multi-plate clutch and having an assembly according to the invention, wherein at least one damper rotary member, preferably two damper rotary members, are received in/on the rotary member in a bearing manner in the axial direction of the assembly towards the rotary member.

Detailed Description

The following explanations of the invention relate to the axial Ax, the rotational axis Ax, the radial Ra and the circumferential Um of the torque transmission device according to the invention with a clutch, damper device and/or the axial Ax, the rotational axis Ax, the radial Ra and the circumferential Um of the drive train of a motor vehicle (e.g. passenger cars, passenger vehicles, motorcycles, commercial vehicles, (heavy) trucks, construction vehicles, engineering machines, utility vehicles, etc. with a gasoline engine or diesel engine). The position information also relates, for example, to a crankshaft, a drive train, a transmission and, if applicable, a converter of an internal combustion engine of the motor vehicle.

The torque transmission device 0 is configured, for example, as an automatic transmission 0, a clutch transmission 0 or a transmission 0. Furthermore, the torque transmission device 0 can be a dual mass converter, a (hydraulic) torque converter, a damper, if appropriate with a damper device or a (trapezoidal) centrifugal force pendulum device, a component or a combination thereof. The clutch 2 can be, for example, a multi-clutch 2, a dual clutch 2, a single clutch 2, or a partial clutch 2 or a clutch device 2, in particular in the drive train of a motor vehicle and is preferably designed as a wet clutch 2. The clutch 2 is here, for example, a (friction) multiplate clutch 2, for example, a main clutch 2, a starting clutch 2, or a converter (tap-off) clutch 2. The damper device 4 is currently embodied as a torsional vibration damper device 4 or a torsional vibration damper device 4. The damper device 4 may have a damper device or a (trapezoidal) centrifugal pendulum device.

According to the invention, a rotary assembly 3 is defined, which has at least one single rotary damper component 30 (second variant of the invention, fig. 9 to 15),40 (first variant of the invention, fig. 1 to 8) and a rotary component 20, in particular a friction lining carrier 20, on the input side of the damper or on the output side of the damper (not shown in the figures). The rotary component 3 can therefore be assigned not only to the damper device 4 but also to the clutch 2 or to the clutch device 2. That is, the rotating assembly 3 may also be referred to as a damper assembly 3 and/or a clutch assembly 3. It is to be noted that the second variant of the invention can also be used on a mechanism or in a device which is different from the clutch 2 or the clutch device 2.

The clutch rotor 20 or rotor 20 of the first variant of the invention can be configured, for example, as an outer or inner friction disk carrier 20, an outer or inner friction disk holder and an outer or inner ring or basically as a tube, which is represented by the term friction disk carrier 20 in the framework of the present description. Furthermore, the rotating component 20 of the second variant of the invention can also be designed as an outer or inner cage or as a coupling or connecting element, which is represented by the term friction lining carrier 20 within the framework of the present description. The embodiment in which the inner disk carrier is present instead of the outer disk carrier 20 is essentially statically reversed, i.e., the force or torque flow occurs not radially outside but radially inside relative to the

rotary damper component

30, 40.

The clutch rotating member 20 or the rotating member 20 according to the first and second variants of the invention is mechanically directly coupled as a rotating assembly 3 with at least one

damper rotating member

30, 40 at least in the circumferential direction Um, i.e. there is no member between them which transmits forces along the circumferential direction Um, i.e. torque between these two members. Here, it is preferred according to the first variant that the separate damper rotary member 40 is preferably fixed in/on the clutch rotary member 20 in both axial directions Ax. Furthermore, according to a second variant, it is preferred that each of the two damper rotary members 30 is fixed in/on the rotary member 20 only in one axial direction Ax, in particular opposite to each other, and a spring force acts between them.

According to the damper arrangement 4 appearing from the observation, see for example fig. 3 or 5, the

damper rotary member

30, 40 can also be referred to as

clutch rotary member

30, 40, but this is represented in the framework of the present description by the term

damper rotary member

30, 40. In such an embodiment of the invention, such a component takes over the basic functions of the clutch 2 and the damper arrangement 4. In the illustrated embodiment of the invention, according to a first modification, the damper rotary member 40 may be configured as a side disc 40, a counter disc 40, a flange 40, a support plate 40, a friction plate 40, or a clutch friction plate 40. In the illustrated embodiment of the invention, according to a second modification, the damper rotary member 30 may be configured as the side disc 30, the counter disc 30, or the flange 30.

The damper device 4 and, if appropriate, the rotating assembly 3 occupy the input side 1 and the output side 5, wherein an energy store 60 of the damper device 4 is arranged in the force flow through the damper device 4 between the input side 1 and the output side 5. The corresponding component or element on this side of the damper device 4 can be referred to as an input element or an output element. The input side 1 and the output side 5 of the damper device 4 can of course be exchanged. The energy store 60 can be designed as a spring element 60, in particular as a linear compression spring 60 or as a bow compression spring 60. In this case, a plurality of spring elements 60 are arranged in one another, as is shown in the present exemplary embodiment. That is, one spring element 60 is inserted inside the second spring element 60.

In operation of the damper arrangement 4, it damps rotational irregularities between its input side 1 and output side 5, for example from the clutch 2, and transmits the torque from the clutch 2 to the transmission input shaft 55 via the hub 50 assigned to the damper arrangement 4, preferably via a spline or spline shaft connection. Due to the narrow installation space and for reasons of cost, it is preferable to keep such a damper device 4 or the mechanical connection of the damper device 4, for example, to the clutch 2, as small as possible in terms of its size and to construct it with as few non-standard components as possible. Furthermore, it is preferable to keep the number of riveted and/or welded connections of the damper device 4 small.

In order to introduce torque, for example from the clutch 2, into the damper arrangement, a further component, for example an intermediate component, is required in the prior art. With such an additional intermediate part, a riveted or welded connection between the intermediate part and the damper arrangement is required. It is therefore desirable to be able to eliminate the intermediate component and, in addition, to also be able to dispense with a riveted and/or welded connection of the intermediate component. The problem is solved by a first and a second variant of the invention, wherein the solution of the problem is explained in detail below only with reference to fig. 1 to 8 of the first variant. As can be seen directly from fig. 9-15, a second variant of the invention also solves this problem.

The solution according to the object of the invention is to attach the damper rotary member 30 directly to the clutch rotary member 20 configured as a friction plate carrier 20. Here, the damper rotating member 30 is fixedly connected to the friction plate carrier 20 at least along the circumferential direction Um except for the mechanical gap. According to the invention, the damper rotary component 30 is arranged in/on the friction disk carrier 20 so as to be movable in one axial direction Ax or in both axial directions Ax. Furthermore, the damper rotary member 30 can be prevented from moving, i.e., fixed, relative to the disk carrier 20 in one axial direction Ax or in both axial directions Ax. Friction lining carrier 20 can be designed in particular as an outer friction lining carrier 20 or as an inner friction lining carrier.

Individual features of the invention are described in detail below with respect to fig. 1-8. Fig. 1 and 2 therefore show a direct torque transmission between the clutch 2 and the damper arrangement 4, wherein a direct connection is established between the friction lining carrier 20 and the damper rotary component 40 of the damper arrangement 4, which is designed as a side disc 40, without intermediate components. Instead of the side discs 40, corresponding discs 40 may also be used. Fig. 4 furthermore shows a torque transmission 0 by means of a direct connection between the friction lining carrier 20 and the damper rotary component 40 of the damper arrangement 4, which is designed as a flange 40, without intermediate components.

Fig. 3 shows the torque transmission by means of the direct connection between the friction lining carrier 20 and the support plate 40 of the friction lining 200 of the clutch 2 and from said support plate directly to the side disk 41 of the damper arrangement 4. Here, the support plate 40 is referred to as a damper rotating member 40, and a corresponding disc 41 may also be used instead of the side disc 41. Fig. 5 also shows the torque transmission via the direct connection between the friction lining carrier 20 and the friction lining 40 or the clutch friction lining 40 of the clutch 2 and the direct transmission from said friction lining to the side disk 41 of the damper arrangement 4. In fig. 3 and 5, the intermediate component can also be omitted, since the function of the intermediate component is taken over here by the support plate 40 or the friction lining 40.

The side disk 40 or counter disk 40 is centered by means of the friction disk carrier 20 and preferably torque-transmitting by means of the tooth profile (input side 1, fig. 1, 2 and 6 to 8). Furthermore, the side disk 41 or counter disk 41 is centered by means of a rivet 410 with the support plate 40 (input side 1, fig. 3) or with a rivet 410 with the friction plate 40 or clutch plate 40 (input side 1, fig. 5). Instead of a rivet connection, a welded connection may also be used. Furthermore, the

side disks

42, 44 or the

counter disks

44, 42 can be centered by a hub connection (output side 5, fig. 4). In this case, the flange 40 of the damper arrangement 4, which is designed as a damper rotary component 40, is then connected to the friction lining carrier 20 (input side 1) in a manner similar to the side disk of fig. 1 or 2.

Friction lining carrier 20 is preferably constructed in one piece, from one piece of material or as a single piece. If a multi-part friction lining carrier 20 is used, its individual parts are connected to one another in a rotationally fixed manner. The friction lining carrier 20 can simultaneously take over the task of guiding and centering not only the (conventional) friction lining 200 (facing carrier) of the clutch 2 but also the task of guiding and centering the side disk 40 or counter disk 40 (fig. 1, 2 and 6 to 8). Furthermore, friction lining carrier 20 can simultaneously perform the task of guiding and centering (conventional) friction lining 200 (lining carrier) as well as the task of guiding and centering flange 40 (fig. 4). In other words, in this case, the torque transmission takes place uniformly via the friction lining carrier 20 (lining carrier) and at least one side disk 40 or counter disk 40 (fig. 1, 2 and 6 to 8) or flange 40 (fig. 4).

Hub 50 (fig. 1-8) and/or hub flange 42 (fig. 1-3 and 5-8) are centered by transmission input shaft 55 and can be positioned axially by bearings 500 (fig. 1-4) or by retaining ring 552 (fig. 8). According to a second variant of the invention, the bearing 500, in particular the axial bearing 500, can be eliminated, or the securing ring 552 can be eliminated. The securing ring 400 in the friction lining carrier 20 serves to axially secure the side disk 40 or the counter disk 40 (fig. 1, 2 and 6 to 8), the flange 40 (fig. 4), the support plate 40 (fig. 3), the friction lining 40 or the clutch plate 40 (fig. 5) at least in one direction (which may optionally be supported by a spacer 402 (fig. 7), which may be a component of the friction lining carrier 20) and thus limits the axial movement of the damper device 4.

Furthermore, the securing ring 400 can be used to support the damper device 4 axially toward the bearing 500 (fig. 1 to 4). This can also be done by means of a shoulder of the transmission input shaft 55 (fig. 8), by means of a fastening ring arranged on the transmission input shaft 55 on the transmission side or by means of a bearing on the transmission input shaft 55. Furthermore, the fixing in both axial directions Ax is achieved by means of a fixing ring 400 and friction plates or clutch plates 40 which are substantially fixed in both axial directions Ax (fig. 5); this also applies to the support plate 40 (fig. 3). In general, the axial fixing in both axial directions Ax can be achieved solely by fixing means in the friction disk carrier 20 (fig. 5 to 7), solely by fixing means at/on the transmission input shaft 55, by combinations thereof, or by means of an axial bearing (500) and fixing means in/on the friction disk carrier 20 (fig. 1 to 4) or at/on the transmission input shaft 55.

Furthermore, instead of or in addition to the fastening ring 400 in the disk carrier 20, a wedge 400 (fig. 6 and 7) of the disk carrier 20 can be used for fastening the associated damper rotary element 40 in at least one axial direction Ax. Similarly, pinning between the friction plate carrier 20 and the associated damper rotational member 40 is also applicable. According to the invention, the vibration damper arrangement 4 can have a spring 420, in particular a disk spring 420, for avoiding or reducing any axial play that may occur. Thus, for example, it is possible for the spring 420 to be arranged between the securing ring 400 and the side disk 40 or counter disk 40 (fig. 2) for adjusting the targeted friction, between the flange 40 and the side disk 42 or counter disk 42 (fig. 4), between the side disk 40 or counter disk 40 and the hub flange 42 (fig. 7), or between the counter disk 44 or the side disk 44 and the hub flange 42 (fig. 8). Application between the securing ring 552 and the hub 50 or hub flange 42 is also permitted.

According to the first modification of the present invention, the intermediate member may be removed, and the rivet connection of the intermediate member between the clutch 2 and the damper device 4 may be omitted by directly attaching the damper device 4 to the friction plate carrier 20. This can also be applied in the second modification of the present invention. Furthermore, it is desirable to design the damper arrangement 4 and the friction lining carrier 20 or another rotating component, for example a cage or another coupling element, which is optionally assigned to it, in such a way that the damper arrangement 4 itself has no rivet connections or weld connections. A second variant of the invention achieves this object, as will become clear from the explanations given below with reference to fig. 9-15.

The solution according to the invention for this purpose consists, on the one hand, in the fact that the damper rotary component 30 or the damper rotary components 30 are attached directly to the clutch rotary component 20, which is configured here as a friction plate carrier 20, similarly to the above (fig. 9 to 15), and, on the other hand, in that an outwardly directed axial force is provided in the damper arrangement 4 (fig. 9 to 12, 14 and 15) or the two side discs 30, 30 (fig. 13) are supported radially on the outside in the axial direction Ax against one another. That is, the friction disk carrier 20 can alternatively also be a cage or a coupling element for positioning, guiding and/or supporting the spring force from or to the damper device 4, which damper device 4 is received directly by the side disks 30, wherein the friction disk carrier 20, the cage or the coupling element serves as a coupling element for the

side disks

30, 30. The damper device 4 therefore has no connecting rivets between the side discs in the axial direction, nor does it require the use of a welded connection or other connection.

The individual features of fig. 9-15 are described in detail below. The friction lining carrier 20, the cage or the coupling element in turn serves as a damper input element 20 or damper output element which receives axial forces instead of a rivet or welded connection between the

side discs

30, 30. The friction plate carrier 20, cage or coupling element serves to center, position and/or support the

side discs

30, 30. If a cage is used, it is implemented by interruptions in the peripheral area. The friction lining carrier 20 can be embodied as a tube with a web-like connecting element between the

side disks

30, 30. The tubular element can thus be configured as a base of a rotor of an electric motor with teeth.

The

side discs

30, 30 are preferably guided centrally by means of a guide element, for example a friction lining carrier 20, in the vicinity of their outer diameter (fig. 9 to 15). In this case, the

side disks

30, 30 can be guided within the disk carrier 20 in the toothing in the axial direction Ax (fig. 9 to 13 and 15), wherein the

side disks

30, 30 can be guided by means of the cylindrical section of the disk carrier 20 or by means of separate webs. Furthermore, the side disks 32 can have toothing systems which transmit the torque into the side disks 34 or into a hub 50 connected to the side disks 34 (fig. 14). Preferably, the teeth of the two

side discs

32, 34 are configured radially inward. In addition, the flange 30 of the damper device 4 is preferably engaged in the friction lining carrier 20 by means of a toothing, which does not have to be axially fixed.

The (first) axial fixing of the at least one side disk 30 is effected, for example, by means of at least one fixing ring 300, spring ring 300 or retaining ring 300 (fig. 9 to 15). The axial force (axial fixation) is supported here by the connecting elements (friction lining carrier, web, cage, coupling element) with the sections of the toothing of the side disk 30. A second support or fixing can likewise be ensured by means of a further fixing ring 300, a spring ring 300 or a retaining ring 300 (fig. 9, 10 and 12 to 15). Furthermore, this can be ensured by means of one or more elements formed by connecting elements (friction lining carrier, web, cage, coupling element) or wedges 300 (fig. 11). Pins may also be used between the friction plate carrier 20 and the side disc or

discs

30, 30.

The outer diameter of the damper arrangement 4 is now transmitted with torque to the outer disk carrier 20 by means of the toothing of at least one side disk 30, but preferably both

side disks

30, 30. Torque transmission takes place similarly in the inner disk carrier on the inner diameter of the damper arrangement 4. By means of one or more springs 320, in particular one or more disk springs, the friction in and/or on the damper device 4 can be set in a targeted manner (fig. 9 to 12, 14 and 15). The axial position or orientation of the hub 50 or the hub flange 32 can thereby be influenced or determined (fig. 9 to 12, 14 and 15), whereby the axial bearing can be eliminated (see fig. 1 to 8 axial bearing 500). In the illustrated embodiment of the second variant, the hub 50 is movably arranged on the transmission input shaft 55 in both axial directions Ax. It may be advantageous to fix the hub 50 to the transmission input shaft 55 in one or both axial directions Ax, if necessary.

Belleville springs 320 may be disposed between hub flange 32 and one side disk 30 (FIGS. 9-12 and 15) on one side. An arrangement on both sides is also possible, i.e. one belleville spring 320 each between the

side discs

30, 30 and the hub flange 32. This can similarly be applied to the flange 30 and one side disc 34 or both side discs 32, 34 (fig. 14). Generally, the springs 320, and in particular the belleville springs 320, are disposed radially inward (fig. 9-12, 14 and 15) and/or radially outward and/or axially inward (fig. 9-12, 14 and 15) and/or outward of the shock absorber device 4. The disk springs 320 can be centered on the shoulders or flanges of the

side disks

30, 32, 34 and/or the

flanges

30, 32.

The flange 30 according to the embodiment of fig. 14 is centered by means of the friction lining carrier 20 and positioned in the axial direction by means of the

side disks

32, 34 and the disk spring 320. For transmitting torque, flange 30 can engage friction lining carrier 20. In the case of the outer disk carrier 20 shown, the toothing is arranged radially on the outside, and in the case of the inner disk carrier the toothing is arranged radially on the inside. Inside the flange 30, for example radially inside, openings 340 (fig. 12 and 15) can be provided in order to allow a volumetric flow of coolant and/or lubricant (oil) in the axial direction and/or in the radial direction. The opening 340 can be additionally or alternatively provided in the hub 50, for example due to engagement with the side disk 32 (fig. 14).

According to the invention, a slide housing 330 (fig. 13 and 15) can be used, which is supported internally, for example, on a curved section of the side disk 30 (fig. 13) or on a connecting element (friction lining carrier, web, cage, coupling element) (fig. 15). Preferably, the slide housing 330 has a torsion-proof element on the periphery, which is fitted into the side disk 30, against torsion in the circumferential direction Um (fig. 15). Furthermore, it is possible to achieve such a rotationally fixed connection to the connecting element. The slip shell 330 serves to support the spring force and protect the connecting elements from wear. It is particularly permissible that these two variants of the invention be implemented together where appropriate. It is also possible to use one or more features of one variant in another variant and, of course, vice versa.
