Description

[0001] “Coupling for media lines and plate-type coupling carrier”

[0002] The invention relates to a coupling for media lines, comprising at least one first plate-like coupling carrier, at least one second plate-like coupling carrier, and at least two plug-in coupling parts. The first coupling carrier has at least one first receptacle, and the second coupling carrier also has at least one first receptacle. The receptacles of the coupling carriers are each designed for inserting and securely holding a plug-in coupling part. Furthermore, the first coupling carrier and the second coupling carrier are designed such that the plug-in coupling parts of corresponding receptacles—here the two first receptacles—that can be arranged in the receptacles can be coupled to one another by joining the first coupling carrier and the second coupling carrier. Furthermore, the invention relates to a plate-like coupling carrier for a coupling, in particular a multiple coupling.

[0003] Couplings for media lines, especially multiple couplings, with plate-like coupling supports are known in the art in a variety of designs for different applications. Such couplings are used whenever different media lines need to be coupled together in an assembly process.

[0004] In particular, to avoid having to connect multiple media lines individually, the media lines are connected to a first or second plate-like coupling support via plug-in coupling parts, so that all media lines are connected to one another by connecting the two coupling supports. In addition to simplifying assembly, this also simplifies maintenance work, for example. However, couplings and coupling supports known from the prior art are limited in their functionality to connecting media lines.

[0005] The present invention is therefore based on the object of specifying a coupling for media lines and a coupling carrier which are expanded in terms of their functionality.

[0006] The aforementioned object is achieved in a generic coupling having the features of the characterizing part of claim 1, namely in that at least one intermediate space is formed between the first coupling carrier and the second coupling carrier in the assembled state. At least one fluid channel opens into the intermediate space, in particular in such a way that a fluid conveyed in the fluid channel can escape into the intermediate space. The fluid channel is, for example, part of the first and / or second coupling carrier.

[0007] For example, the fluid channel is formed integrally with the first coupling carrier. Alternatively, the fluid channel is formed in one of the plug-in coupling parts, which is arranged in one of the receptacles. At least one damping element made of a gas-permeable, in particular open-pore, material is arranged in the intermediate space such that a fluid flowing out of the fluid channel can flow through the damping element. Preferably, the fluid flowing out of the fluid channel must flow through the damping element.

[0008] The term "media line" generally refers to line connections for any flow and / or pressure media, such as gases or liquids. Media lines are generally pipes or hoses, as well as their connecting and connection elements, which are part of a system for conveying a medium. Such media lines are generally made of plastic.

[0009] The plate-like coupling supports preferably have a substantially flat base surface in which the receptacles are formed. The base surface is preferably surrounded by a circumferential side wall. Each receptacle has fixing means, e.g. locking arms with locking projections, for holding, in particular in a form-fitting or force-fitting manner, an insertable plug-in coupling part. The plug-in coupling parts are in particular inserted into the respective receptacle. The first and the second coupling supports each have at least one first receptacle, which are arranged opposite one another in the assembled state. It is also preferably provided that each coupling support has more than one receptacle, for example at least or exactly two or at least or exactly three or at least or exactly four or at least or exactly five or at least or exactly six receptacles for plug-in coupling parts.Each plug-in coupling part has, in particular, a fluid channel or a part of a fluid channel and at least one connection interface. Furthermore, it is particularly provided that at least one coupling carrier has at least one second fluid channel with at least one first connection interface and at least one second connection interface, which are preferably arranged at an angle to one another. The fluid channel, which opens into the intermediate space, has at least one connection interface, for example, a mandrel profile.

[0010] Particularly preferably, the multiple coupling has a plug-in coupling part for each receptacle of a coupling carrier. However, it is also possible that, depending on the intended use, only some of the receptacles of a coupling carrier are equipped with plug-in coupling parts.

[0011] Preferably, at least two corresponding plug-in coupling parts for the two first receptacles of the coupling carrier are made of brass or plastic. With a total of two receptacles per coupling carrier, in particular at least four plug-in coupling parts - two for each coupling carrier - are made of brass or plastic. Preferably, all plug-in coupling parts are made of brass or plastic. For example, a plug-in coupling part made of brass or plastic has a connection dome. The first coupling carrier and the second coupling carrier can preferably be connected to one another in exactly one orientation, in particular by locking and / or screwing or by being locked and / or screwed. The first coupling carrier and the second coupling carrier can in particular be connected directly to one another.For example, it is provided that the first coupling carrier and the second coupling carrier each have at least one alignment means that enables the first coupling carrier and the second coupling carrier to be joined together in only one alignment with one another, whereby the media lines connected or connectable to the coupling carriers are correctly assigned to one another.

[0012] It is preferably provided that the first coupling carrier and / or the second coupling carrier has at least one, preferably two recesses, in particular for receiving threaded nuts or threaded sleeves, for screwing the two coupling carriers together.

[0013] The plug-in coupling parts are designed such that the two plug-in coupling parts are fluidically connected to one another by two corresponding receptacles, namely those receptacles of the first coupling carrier and the second coupling carrier which are opposite one another in the assembled state, when the first coupling carrier and the second coupling carrier are joined together. Each plug-in coupling part has at least one interface for connecting to another plug-in coupling part. When two plug-in coupling parts are intended to be joined together, at least one interface of one of the two plug-in coupling parts has at least one sealing means. On the side facing away from the coupling carrier in the assembled state, a plug-in coupling part preferably has a connection interface to a media line, for example a connection dome or a plug-in socket, or another media line interface or a functional component, for example a valve.Preferably, the connecting interface of the fluid channel is formed parallel to the joining direction of the first coupling carrier and the second coupling carrier. For example, the first receptacle of the first coupling carrier is aligned parallel to the joining direction.

[0014] For example, it is provided that the first clutch carrier is manufactured in one piece, in particular by an injection molding process, and / or that the second clutch carrier is manufactured in one piece, in particular by an injection molding process. Preferably, the first clutch carrier and / or the second clutch carrier are made of a plastic, in particular a glass fiber reinforced plastic. In particular, the glass fiber content in the plastic is between 25% and 45%, preferably 30%.

[0015] The damping element arranged in the intermediate space is designed to be gas-permeable, in particular fluid-permeable. The damping element is particularly preferably designed for the flow of pressurised gases, in particular compressed air. The damping element in particular has such a porosity, in particular microporosity, that the damping element can be penetrated by a pressurised gas. The damping element preferably serves to reduce or dampen the noise of a fluid, in particular gas, escaping from the fluid channel. For example, a volume of approximately 0.1 to 0.4 litres under pressure, e.g. between 5 and 9 bar, is released via the fluid channel over a short period of time. This pressure surge escapes from the fluid channel into the intermediate space. In order to prevent or dampen any noise resulting from this.To dampen, the damping element made of the gas-permeable, in particular porous, material is arranged in the intermediate space.

[0016] In particular, it is provided that the damping element is made of a filter material that, in particular, slows down the flow velocity of a fluid emerging from the fluid channel. The damping element is made, for example, of a sintered material. Sintered metals, in particular sheets made of sintered metals, sintered ceramics, or sintered plastics, have proven to be particularly suitable sintered materials. Examples of suitable metals include aluminum, bronze, nickel, titanium, or alloys, e.g., Monel (material number 2.4360, 65% nickel, 33% copper, and 2% iron). The damping element is preferably a highly porous sintered metal filter.

[0017] In particular, the damping element is made of plastic, for example, high-density polyethylene (HDPE), low-density polyethylene (LDPE), polytetrafluoroethylene (PTFE), or ultra-high-molecular-weight polyethylene (UHMW-PE). For example, it is a sintered plastic. The damping element is particularly preferably made of microporous HDPE, porous HDPE, porous LDPE, porous UHMW-PE, or porous PTFE.

[0018] It is also envisaged that the damping element is constructed in multiple layers of the same material with different properties, or in multiple layers of different materials, particularly in multiple layers in the flow direction. For example, the damping element is constructed in multiple layers of a gas-permeable plastic and a gas-permeable metal.

[0019] A sintered metal with a theoretical pore size between 75 pm and 225 pm, in particular 100 pm or 200 pm, is particularly preferred. The damping element is made, for example, from sintered metal spheres with a diameter between 0.25 mm and 0.8 mm, in particular between 0.35 mm and 0.45 mm or between 0.65 mm and 0.7 mm. After sintering, the metal spheres are preferably arranged in between 2 and 5 layers, in particular between 2 and 2.5 layers or between 4 and 5 layers. Furthermore, it is provided that the damping element has or is formed from at least one knitted fabric or a braid made of wire, in particular of metal wire.

[0020] Particularly preferably, the damping element is designed as a plate-shaped, circular disc with a thickness between 0.5 mm and 3 mm. The damping element, in particular a plate-shaped one, is preferably arranged with a surface exposed to the flow substantially orthogonal to a central axis of the fluid channel. However, it is also particularly contemplated that a surface exposed to the flow of the damping element is arranged at an angle to a central axis of the fluid channel in order to ensure an oblique flow to the damping element.

[0021] The damping element is preferably attached to one of the coupling supports and / or fastened between the coupling supports. In particular, it is also provided that the fluid channel, which opens into the intermediate space, is formed in a plug-in coupling part arranged in a receptacle of the first coupling support. The damping element is held in the corresponding receptacle of the second coupling support, which is particularly opposite in the assembled state, so that fluid flowing out of the fluid channel passes through the damping element. For example, the damping element is held on a support in the receptacle, which advantageously cooperates with fastening means of the receptacle.

[0022] The invention has the advantage over the prior art that a pressurized volume, for example a pneumatic shift cylinder of a commercial vehicle, can be easily released into the space between the two clutch supports with no or very little noise. The connection effort is reduced because connection interfaces of the clutch can be used. A first embodiment of the clutch provides that the fluid channel is at least partially, in particular completely, covered by the damping element and / or that the damping element protrudes at least partially into the fluid channel. Particularly preferably, the damping element is plate-shaped and completely covers the mouth of the fluid channel or a volume arranged behind the mouth of the fluid channel, such that all of the fluid escaping from the fluid channel must pass through the damping element.In particular, the damping element completely covers a free cross-section of the fluid channel or a cross-sectional extension of the fluid channel. Alternatively or additionally, the damping element extends at least partially into the fluid channel.

[0023] According to a further embodiment of the coupling, it has proven particularly advantageous if the damping element is held in a force-fitting and / or form-fitting manner, in particular on the first coupling carrier. For example, the first coupling carrier has at least one recess in which the damping element is at least partially arranged. The damping element is, for example, fastened to the coupling carrier in a form-fitting manner or is clamped in the coupling carrier under the action of force, so that in the assembled state it is arranged in the intermediate space on or in front of the fluid channel. Fastening to the first coupling carrier has the advantage that the damping element is secured during transport of the coupling or the coupling carrier, in particular even before the coupling is assembled.

[0024] According to a particularly preferred embodiment, it is also provided that the first coupling support has at least one elastic retaining arm, and that the damping element can be fastened to the coupling support by means of the retaining arm. Preferably, the elastic retaining arm is designed such that it elastically deflects upon insertion of the damping element and subsequently engages around the damping element, for example, with a locking recess. The damping element is preferably held in a form-fitting manner between the retaining arm and an opposite side wall of the coupling support. The elastic retaining arm clamps the damping element, in particular, against a side wall of the first coupling support.

[0025] Preferably, the damping element is designed as a substantially circular disc, and the distance between the elastic retaining arm and an opposite side wall of the first coupling carrier is less than the diameter of the damping element. For example, the elastic retaining arm deflects during assembly to at least temporarily increase the distance to the side wall to the diameter of the damping element. Once a center point has passed between the retaining arm and the side wall, the locking arm springs back to its original position and secures the damping element.

[0026] A further embodiment of the coupling provides that the first coupling carrier has at least one section in a sidewall edge region that is adapted to an outer contour of the damping element. The sidewall region is shaped such that at least one section of it rests against the outer contour of the damping element. If, for example, the damping element is circular, the sidewall region is designed as a circular segment. In particular, it is provided that the section of the sidewall region has a circular contour or a radius.

[0027] Particularly preferably, this section is arranged opposite the elastic retaining arm. For example, in the assembled state, the damping element is held between the elastic retaining arm and the section of the side wall. Preferably, the distance between the elastic retaining arm and the section of the side wall is less than the diameter of the preferably circular damping element, so that the damping element can be held essentially without clamping force, in particular purely by positive engagement.In order to advantageously and reliably secure the damping element in the intermediate space against loosening due to vibrations, a further embodiment provides that the first coupling carrier has at least one dome which, in the assembled state, interacts with a dome formed on the second coupling carrier, for example by a screw being passed through a recess in the domes in order to fasten the coupling and / or connect the coupling carriers. The dome on the first coupling carrier has at least one recess into which the damping element can at least partially enter. Particularly advantageously, the recess is arranged such that, in the assembled state, the damping element is clamped between the recess on the dome of the first coupling carrier and the second coupling carrier, in particular an opposite dome of the second coupling carrier. In particular, each coupling carrier has at least or exactly two domes.

[0028] In order to fix the damping element, in particular finally, in the space between the first coupling carrier and the second coupling carrier, a further embodiment of the coupling provides that the second coupling carrier has at least one clamping element, and that the clamping element effects a force on the damping element when the first coupling carrier and the second coupling carrier are joined together. The force is preferably exerted by the clamping element orthogonally on a surface of the damping element. The force is preferably exerted by the clamping element off-center on a circular damping element. The clamping element is designed, for example, as a cylindrical web, advantageously in one piece with the second coupling carrier. It is particularly preferably provided that the clamping element effects such a force on the damping element that the damping element is at least partially elastically deformed. For this purpose, the clamping element is, for example,slightly longer than a parting plane between the first coupling carrier and the second coupling carrier. A further embodiment of the coupling provides that the first coupling carrier has at least one counter-bearing for the damping element, in particular for interacting with the clamping element. In the assembled state, the counter-bearing is preferably arranged opposite the clamping element. For example, the counter-bearing comprises at least three wall sections that converge towards a central web and are connected to it. In the assembled state of the first coupling carrier and the second coupling carrier, the damping element is preferably clamped between the clamping element and the counter-bearing in order to reliably hold the damping element in its position in the intermediate space.

[0029] Particularly preferably, the counterbearing is designed to be set back, particularly relative to other support areas for the damping element, particularly relative to the recess in a dome, so that the set-back arrangement of the counterbearing causes elastic deformation of the damping element by the clamping element. This preload or elastic deformation of the damping element reliably prevents the damping element from becoming loose during use.

[0030] The assembly of the coupling can be simplified in a simple manner by providing the first coupling support with at least one opening, in particular a slot-shaped opening, and by allowing the damping element to be introduced into the intermediate space through the opening. For example, the opening is formed in a side wall, preferably in a corner region, of a coupling support. If the coupling support is plate-shaped, in particular circular, the opening is preferably slot-shaped. The opening is preferably aligned substantially parallel to a parting plane between the first coupling support and the second coupling support.

[0031] For example, the opening is arranged in such a way that when, for example, a circular damping element is pushed through the opening, the damping element is supported on the section of the side wall opposite the holding arm and, due to the circular shape, deforms the holding arm until the diameter of the damping element has passed between the section of the side wall and the flexible holding arm, so that the holding arm, after the diameter has passed through, can return to its original position and thereby prevents the damping element from escaping through the opening.

[0032] Advantageously, at least one retaining projection is arranged in the region of the opening. When the first coupling carrier and the second coupling carrier are assembled, the damping element advantageously rests against the retaining projection, which prevents the damping element from escaping through the opening. Preferably, the height of the opening above the retaining projection approximately corresponds to the thickness of the damping element. This allows the damping element to be inserted through the opening above the retaining projection, but subsequently, the damping element can no longer exit through the opening when it rests against the retaining projection. Consequently, the damping element can override the retaining projection when inserted into the opening.

[0033] A further embodiment of the coupling provides that the fluid channel in the first coupling carrier has at least one cross-sectional widening. The cross-sectional widening preferably forms the mouth of the fluid channel. In particular, the cross-sectional widening is approximately cylindrical. The damping element is preferably arranged in the region of the cross-sectional widening. Preferably, the damping element completely covers the cross-sectional widening. Due to the cross-sectional widening, the effective area for the fluid escaping from the fluid channel on the damping element is larger, so that pressure can be reduced more quickly by the fluid escaping from the fluid channel being able to pass through the damping element over a larger area. In addition, the cross-sectional widening prevents a backflow of the fluid, thereby advantageously preventing excessive back pressure, which could impair the functionality of, for example, a pneumatic switching cylinder.

[0034] Depending on the amount of fluid escaping from the fluid channel into the intermediate space, it has proven advantageous according to a further embodiment of the coupling if the first coupling carrier has at least one venting recess. The fluid entering the intermediate space from the fluid channel can escape through the venting recess into the surroundings of the coupling without pressure building up in the intermediate space. It is preferably provided that the fluid can escape both through the opening for introducing the damping element and through the venting recess. The first coupling carrier preferably has a plurality of venting recesses. For example, the venting recesses are formed in a side wall of the coupling carrier. It is particularly preferably provided that the venting recess is arranged directly adjacent to the second coupling carrier.As a result, a side wall of the second coupling carrier also limits the ventilation recess when assembled.

[0035] The invention further relates to a plate-type clutch carrier for a clutch according to one of the described embodiments. The plate-type clutch carrier preferably corresponds to the first clutch carrier according to at least one of the described embodiments. In particular, the plate-type clutch carrier has at least one fluid channel, which opens in particular on a rear side of the plate-type clutch carrier. The at least one damping element made of a gas-permeable, in particular open-pore, material is arranged on the clutch carrier in such a way that a fluid flowing out of the fluid channel can flow through the damping element.

[0036] The invention is particularly suitable for use on commercial vehicle components, in particular for pre-assembling a commercial vehicle axle with at least one electric motor, a manual transmission, and a differential. The use of a coupling according to the invention, in particular a multiple coupling, enables the filling and testing of the commercial vehicle axle prior to its actual assembly on the vehicle frame.

[0048] In the various figures of the drawing, identical parts are always provided with the same reference symbols.

[0049] With regard to the following description, it is claimed that the invention is not limited to the exemplary embodiments and not to all or several features of described combinations of features, but rather each individual partial feature of the / each exemplary embodiment is also important for the subject matter of the invention, even independently of all other partial features described in connection therewith, and also in combination with any features of another exemplary embodiment.

[0050] Fig. 1, 2, 4, 5 and 6 show an embodiment of a first plate-like coupling carrier 2 for a coupling 1, in particular a multiple coupling 1, for media lines, as shown, for example, in Fig. 7 and 8, in various views. Fig. 3 shows an embodiment of a second plate-like coupling carrier 3 for a coupling 1 according to Fig. 7 and 8. Fig. 9 shows an embodiment of a coupling 1 according to Fig. 7 and 8 in a section, wherein a plug-in coupling part 4 is inserted into each of the second receptacles 6.

[0051] In the illustrated embodiment, each of the coupling supports 2, 3 has two plug-in coupling parts 4 (see, for example, Fig. 9), wherein each plug-in coupling part 4 can be inserted and fixed into a first receptacle 5 or a second receptacle 6. The first coupling support 2 and the second coupling support 3 are designed such that the plug-in coupling parts 4 of corresponding receptacles 5, 6 arranged in the receptacles 5, 6 can be coupled by joining the first coupling support 2 and the second coupling support 3 when the coupling supports 2, 3 are joined together to form a coupling according to Figs. 7 and 8 (see in particular Fig. 9). A first fluid channel 7 is formed in each of the plug-in coupling parts 4. The first coupling support 2 has four locking elements 27 which, in the assembled state, positively connect the first coupling support 2 and the second coupling support 3 (see in particular Figs. 7 and 8).

[0052] 1, 2, 4, 5, 7 and 8, the first clutch carrier 2 has a total of three second fluid channels 8 which are directly connected to the first clutch carrier 2. The three second fluid channels 8 each have a first connection interface 9 and a second connection interface 10. Furthermore, the first clutch carrier 2 has a third fluid channel 11 which has only a second connection interface 10, here in the form of a dome profile. In the assembled state, the third fluid channel 11 opens into an intermediate space 12 (see, for example, Fig. 8) between the first clutch carrier 2 and the second clutch carrier 3. The intermediate space 12 is formed by the corresponding cavities 12a of the first clutch carrier 2 and 12b of the second clutch carrier 3. Fig. 1, 2 and 5 show a coupling carrier rear side 2a of the first coupling carrier 2, at which the third fluid channel 11 opens, so that in the assembled state it opens into the intermediate space 12.

[0053] A damping element 13 made of an open-pore material, here sintered metal, is arranged on the fluid channel 11 opening into the intermediate space in such a way that the damping element 13 can be flowed through by a fluid flowing out of the fluid channel 11 into the intermediate space 12. In the illustrated embodiment, the damping element 13 is designed as a plate-shaped circular disk - see in particular Figs. 4 and 6. The damping element 13 is arranged in such a way that the fluid must flow completely through the damping element 13. The entire free cross-section of the fluid channel 11 is covered by the damping element (see in particular Figs. 1, 6 and 8). This advantageously reduces the pressure of the fluid and minimizes the noise caused by the outflowing fluid. In particular, the damping element 13 acts as a diffuser, dividing the fluid flow emerging from the fluid channel 11 into many individual fluid flows, in particular due to its porous shape.

[0054] The damping element 13 is held in a force-fitting and form-fitting manner on the first coupling carrier 2. For this purpose, the first coupling carrier 2 has an elastic holding arm 14 (see Figs. 1, 2, 5 and 6) which has a locking recess 15 for receiving the damping element 13.

[0055] When mounted on the first coupling carrier 2 according to Figs. 1 and 6, the damping element 13 rests in a recess 16 on a dome 17 and in a recess 6a on the second receptacle 6 in the first coupling carrier 2. The recesses 16, 6a have a radius that corresponds to the radius of the damping element 13. The height of the recesses 16, 6a corresponds approximately to the thickness of the damping element 13 or is slightly less, so that bracing with an opposite dome 20 of the second coupling carrier 3 is possible (see Figs. 3 and 8).

[0056] The holding arm 14 and a section 18 of a side wall 19 of the first coupling carrier 2 are arranged relative to one another, in particular according to Figs. 1 and 6, such that the distance A of the section 18 of the side wall 19 from the elastic holding arm 14 is less than a diameter of the damping element 13. As a result, at least the elastic holding arm 14 is deformed upon insertion of the damping element 13 until the diameter at the narrowest point between section 18 and holding arm 14, which corresponds to the distance A, has passed through, i.e. the center point M of the damping element is arranged behind the smallest distance A between the section 18 and the elastic holding arm 14. As a result, the damping element 13 is already fastened to the first coupling carrier 2 in the sense of a transport lock.

[0057] When the first clutch carrier 2 and the second clutch carrier 3 are joined to form a clutch 1, the damping element 13—as already described above—is clamped at least in the recess 16 on the dome 17, at least between the dome 17 and an opposite dome 20 of the second clutch carrier 3. Furthermore, the second clutch carrier 3 has a clamping element 21 in the form of a cylindrical projection, which, in the assembled state according to Fig. 8, acts on a surface of the damping element 13 such that the damping element 13 is elastically deformed, namely, deformed or bent downwards according to Fig. 8. The clamping element 21 is arranged such that it acts off-center, i.e., next to the center point M, on the damping element 13. To effect the elastic deformation, the clamping element 21 is, in particular, somewhat longer than a parting plane T between the first clutch carrier 2 and the second clutch carrier 3.

[0058] According to Figs. 2 and 8, a counter bearing 22 is provided on the first coupling carrier 2, here in the form of a web with three walls running centrally to the web. In Fig. 8, the section is through the web and a wall of the counter bearing 22. The counter bearing 22 is set back from the remaining bearing points, for example the recess 16 of the damping element 13 (downward according to Fig. 8), so that the clamping element 21 can deform the damping element 13 in the direction of the counter bearing 22 until the damping element 13 rests against the counter bearing 22 with elastic deformation. The damping element 13 is thereby reliably fixed in the intermediate space 12.

[0059] To insert the damping element 13 into the intermediate space 12, in particular into the first coupling carrier 2, the first coupling carrier 2 has a slot-shaped opening 23 according to Figs. 2, 4, 6, 7, and 8. The opening 23 is formed in a corner region of the first coupling carrier 2 in a side wall 19.

[0060] Furthermore, the first coupling carrier 2 according to Fig. 2, 6, 7 and 8 has a retaining projection 24 which is arranged in the opening 23 and projects at least partially into the opening 23. During assembly, the damping element 13 can extend beyond the retaining projection 24, since the remaining height of the opening 23 is sufficient for this. However, after the second coupling carrier 3 has been mounted, the clamping element 21 presses the damping element 13 towards the first coupling carrier 2, so that the damping element 13 also rests against a side edge of the retaining projection 24 and can no longer protrude through the opening 23. At the same time, the elastic deformation and the bracing between the clamping element 21 and the counter bearing 22 take place. As a result, the damping element 13 is finally and reliably fixed in the intermediate space 12.

[0061] According to Figs. 2, 5, and 8, the fluid channel 11 has a cross-sectional widening 25 in the first clutch carrier 2. The cross-sectional widening 25 is completely covered by the damping element 13. This cross-sectional widening 25 increases the effective area for a fluid escaping from the fluid channel 11, so that the fluid can more easily pass through the damping element 13.

[0062] To allow fluid entering the intermediate space 12 to escape into the environment, the first clutch carrier 2 has three venting recesses 26 located in an edge region of the side wall 19 adjacent to the second clutch carrier 3. The fluid entering the intermediate space 12 from the fluid channel 11 can then escape into the environment through the venting recesses 26.

[0063] The invention is not limited to the illustrated and described embodiments, but also encompasses all equivalent embodiments within the meaning of the invention. It is expressly emphasized that the embodiments are not limited to all features in combination; rather, each individual partial feature can also have an inventive significance in itself, independently of all other partial features. Furthermore, the invention is not yet limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed as a whole.
