Stent system

Technical Field

The invention relates to a carrier system for a friction clutch.

Background

Friction clutches are known for selectively transmitting torque between an input side and an output side, which friction clutches have a friction disk carrier. The friction lining carrier is connected in a torque-locking manner to at least one friction lining or steel friction lining. The friction lining carrier is connected to the flange by riveting.

Disclosure of Invention

It is an object of the present invention to provide an improved carrier system for a friction clutch.

This object is achieved by the carrier system for a friction clutch according to the invention. Advantageous embodiments are given in the preferred embodiments.

According to the invention, an improved carrier system for a friction clutch can be provided by: the carrier system is mounted so as to be rotatable about an axis of rotation and has a friction lining carrier and a joint element. The friction lining carrier can be coupled to a friction pair of the friction clutch. The coupling piece can be coupled to the input side or the output side of the friction clutch. The friction plate holder and the joint member are connected to each other by a connecting portion. The connecting part is constructed to be detachable without damage.

In this way, the assembly and disassembly of the friction clutch can be simplified. Furthermore, the axial installation space required for the connection between the adapter piece and the friction lining carrier is reduced. In general, the friction clutch can be designed to be narrower in the axial direction, or additional friction pairs can be provided with the same installation space requirement, so that the friction clutch can transmit higher torques than known friction clutches.

In this case, it is particularly advantageous if the connection is designed as a bayonet connection. Such a connection is particularly suitable for use in a friction clutch for a motorcycle, in which the friction pair must be replaced at a defined distance.

In another embodiment, the adapter has a first opening, wherein the first opening has a first section extending in the circumferential direction and a second section adjoining the first section. The first section has a smaller cross section in the radial direction than the second section.

In this case, it is particularly advantageous if the friction lining carrier has a counter element extending substantially in the axial direction, wherein the counter element passes at least partially through the first opening in the first section.

In a further embodiment, the friction lining carrier has a receptacle, wherein the receptacle extends substantially in the circumferential direction and is preferably of channel-shaped configuration. The socket is fitted into the receiving portion. In a further embodiment, the receptacle is arranged radially inside on the mating element and is configured in the axial direction in accordance with the socket, wherein the receptacle preferably extends in the circumferential direction over the entire extension of the mating element.

In order to securely fix the friction lining carrier to the adapter, a securing device is provided, wherein the securing device engages in the second section and is designed to prevent a rotation of the friction lining carrier relative to the adapter at least partially by a contact of the friction lining carrier on the securing device.

It is particularly advantageous here if the securing device comprises a securing element and a ring section, wherein the ring section extends substantially in the radial direction, wherein the securing element is arranged on the ring section, wherein the securing element extends substantially in the axial direction.

It is also advantageous if the securing element is connected with a fixed end to the ring section, wherein the securing element has an abutment surface at a free end, wherein the first opening has a circumferential surface, wherein the securing element is designed such that the abutment surface is pressed against the circumferential surface and the securing device is fixed in a force-fitting manner to the friction lining carrier.

It is furthermore advantageous if the ring segment has a second opening, wherein the second opening has substantially the same extent in the circumferential direction as the first opening, wherein the fitting element fits into the second opening, wherein the securing element is arranged to abut on the second opening.

Detailed Description

Fig. 1 shows a perspective view of a carrier system 10 for a friction clutch 15. To better illustrate the construction of the mounting system 10, fig. 2 and 3 show perspective views of the mounting system 10 shown in fig. 1 in a partially installed state, respectively. Fig. 4 illustrates a perspective view of the safety 20 of the rack system 10 shown in fig. 1-3. Fig. 1 to 4 are collectively described below.

The friction clutch 15 is mounted so as to be rotatable about an axis of rotation 25 and is designed to selectively provide a torque-locking connection of the input side 30 to the output side 35. The input side 30 may, for example, be connected with a piston engine, while the opposite output side 35 may, for example, be coupled with a transmission input shaft. Of course, the input side 30 may be swapped with the output side 35. Furthermore, the friction clutch 15 comprises a pressure head 40, which is coupled to an actuating device, not shown. The pressure head 40 is arranged radially inside with respect to the adapter piece 50. The pressure head 40 is arranged axially displaceable relative to the adapter piece 50.

The carrier system 10 includes a first friction plate carrier 45 and a joint 50. The first friction lining carrier 45 is connected to the adapter 50 in a torque-locking manner by a connecting part 55, which is designed as a bayonet connection. The connecting part 55 is designed in this case to be able to be removed without damage and is designed to transmit torque between the first friction lining carrier 45 and the adapter 50.

Furthermore, the friction clutch 15 has a friction device 56. The friction device 56 comprises a plurality of first friction pairs 60 and a plurality of second friction pairs 65, which are arranged alternately axially adjacent to one another.

The first friction lining carrier 45 has a first toothing 75 and a supporting section 80. The support section 80 extends substantially perpendicularly to the rotational axis 25 and is connected to the first toothing 75. As a result, first friction lining carrier 45 has a substantially pot-shaped configuration. In this embodiment, the first friction pair 60 is fitted into the first tooth 75 on the radially inner side. As a result, first friction partner 60 is connected to first friction disk carrier 45 in a torque-locking manner and is axially displaceable. The first friction pair 60 is designed here as a steel friction disk and has no friction linings, for example. The second friction pair 65 is configured as a facing friction plate. It is of course also conceivable for the first friction pair 60 to be configured as a facing friction plate and for the second friction pair 65 to be configured as a friction plate without a friction facing. Of course, other configurations of the friction device 56 are also contemplated.

Furthermore, the friction clutch 15 comprises a second friction lining carrier 70. The second friction lining carrier 70 has a second tooth 71, which is arranged radially on the inside with respect to the friction device 56. The second friction pair engages radially on the outside into the second toothing 71 and is connected to the second friction lining carrier 70 in a torque-locking manner and axially movably via the second toothing 71. Furthermore, the second friction disk carrier 70 is connected in a torque-locking manner to the input side 30, and the adapter piece 50 is connected in a torque-locking manner to the output side 35. In order to press the friction pairs 60,65 against one another and thus to provide a frictional engagement between the friction pairs 60,65, the pressure head 40 is designed to introduce an actuating force F from the actuating device into the friction device 56. The support section 80 serves here to: supporting the operating force introduced into the friction device 56. Thus, the input side 30 can be selectively coupled with the output side 35 in a torque-locking manner by means of friction locking.

A counter element 85 is arranged axially adjacent to the first toothing 75 on the side opposite the support section 80. The counter element 85 here has, for example, parts of the toothing 75, so that it is thus of particularly rigid design. Of course, it is also contemplated that the mating element 85 could be otherwise configured. The mating element 85 extends substantially in the axial direction. Of course, it is also conceivable for the mating element 85 to be oriented obliquely with respect to the axis of rotation 25 and also to extend partially radially inward or outward. Radially on the inside, a receptacle 90 is provided on the mating element 85, wherein the receptacle 90 is of substantially trough-shaped configuration and extends substantially in the circumferential direction over the entire extension of the mating element 85. Of course, it is also conceivable for the receptacle 90 to extend in the circumferential direction only partially over the circumferential extent of the mating element 85.

The socket 50 has a first opening 95. The first opening 95 has a first section 100 and a second section 105. The first segment 100 is arranged adjacent to the second segment 105 in the circumferential direction. The first section 100 has a smaller cross section in the radial direction than the second section 105. The cross section of the second portion 105 is adapted in the radial direction to the radial extent of the mating element 85 and has a radial extent which is at least the same as the mating element 85 or greater than the mating element 85. The second section 105 is sufficiently wide in the circumferential direction so that the engagement element 85 can be moved in the axial direction by the second section 105 when the first friction lining carrier 45 is mounted on the adapter 50. The receptacle 90 is formed at least in the axial direction on the adapter part 50, preferably also in the radial direction on the first portion 100. It is particularly advantageous here if the receptacle 90 has an axial extent in the axial direction which substantially corresponds to the thickness of the socket 50 in the first region 110.

When the adapter 50 is mounted on the first friction lining carrier 45, the counter element 85 is initially pushed through the second portion 105. Then, in contrast, the first friction plate carrier 45 is twisted relative to the adapter 50 in the circumferential direction in the direction of the first section 100, so that the adapter 50 is fitted into the receptacle 90 on the radially inner side in a region 110 arranged radially inwardly of the first section 100.

The safety device 20 is configured to: after the region 110 has been inserted into the receptacle 90, the first friction disk carrier 45 is prevented from twisting relative to the adapter 50 (see fig. 1). To this end, the securing device 20 comprises a securing element 115 and a ring section 120. The ring section 120 is arranged here to abut axially on the side of the fitting 50 opposite the friction device 56. The ring section 120 is configured in a disk-like manner and extends substantially in the radial direction. The securing element 115 is arranged on the ring segment 120 in each case.

The fuse element 115 has a fixed end 125 and a free end 130. The securing element 115 is connected to the ring segment 120 with a fastening end 125. The securing element 115 extends substantially in the axial direction. Here, an abutment surface 135 is provided radially on the outside at the free end 130.

The ring section 120 has a plurality of second openings 140. The second opening 140 has substantially the same extension in the circumferential direction as the first opening 95. In the radial direction, the second opening is configured analogously to the second section 105 or corresponds to the radial extent of the mating element 95. Here, the fixed end 125 is arranged to abut on the first side 145 of the second opening 140. The first side 145 extends here substantially in the radial direction.

The securing element 115 has an extent in the circumferential direction which is adapted to the mating element 85 in such a way that the mating element 85 and the securing element 115 together have the extent of the first opening 95 or the second opening 140. The ring segment 120 rests with the first end face 150 against the second end face 155 of the socket 50, whereby the securing element 115 engages in the first opening 95. Further, the fitting member 85 is fitted into the second opening 140. The position of the mating element 85 relative to the socket 50 in the circumferential direction is thereby ensured at this time: a second side 160 of the mating element 85 facing the securing element 115 rests against a third side 165 of the securing element 115. In contrast, the fourth side 170 of the securing element 115 rests against the fifth side 175 of the first opening 95. Opposite the fourth side 170 in the circumferential direction, the sixth side 180 rests against the seventh side 185 of the second opening 140 and against the eighth side 190 of the first opening 95. By the abutment of the flanks 145,160,165,170,175,180,185,190, a rotation of the first plate carrier 45 in the circumferential direction relative to the adapter part 50 is prevented by the flanks 145,160,165,170,175,180,185,190 coming into contact with one another.

To fix the axial position of the securing device 20, the securing element 115 presses the contact surface 135 radially outward against the outer circumferential surface 195 of the first opening 95. The securing device 20 is thereby connected in a force-fitting manner to the socket 50. Of course, it is also conceivable to arrange a detent lug on the free end 130, which detent lug engages the fitting 50 on the side of the fitting 50 facing the friction device 56. It is also conceivable to provide a spring device, in particular a belleville spring, which presses the securing device 20 against the adapter piece 50.

In this embodiment, the friction clutch 15 is designed as a dual clutch, wherein the coupling piece 50 is connected in a torque-locking manner to a further friction lining carrier (not shown). Of course, it is also conceivable for the friction clutch 15 to be constructed as a wet friction clutch or a dry friction clutch or in another manner.

The configuration of the stent system 10 depicted in fig. 1 through 4 has the following advantages: the carrier system 10 is axially shorter than in the conventionally known embodiment, as a result of which the installation space requirement of the friction clutch 15 can be reduced overall. Of course, it is contemplated that the stent system 10 may be otherwise configured. In this case, it is particularly conceivable for the first friction lining carrier 45 to be designed as an outer friction lining carrier. It is also contemplated that the connection 55 may be otherwise configured. It is essential here, however, that the connection 55 can be detached without damage. In this way, both the assembly of the friction clutch 15 and the disassembly of the friction clutch 15 can be carried out in a simple manner, in particular in the case of motorcycle clutches in which the friction partners 60,65 have to be replaced at a defined distance.
