[0002] “Multiple coupling for media lines and coupling supports”

[0003] The invention relates to a multiple 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. The invention further relates to a plate-like coupling carrier for a multiple coupling.

[0004] Multiple couplings for media lines with plate-like coupling supports are known in the prior art in a variety of designs for different applications. Multiple couplings are always used when a plurality of media lines need to be coupled together simultaneously in an assembly process. To avoid having to connect all media lines individually, the media lines are connected to a first or second plate-like coupling support via plug-in coupling parts, so that by connecting the two coupling supports, all media lines are connected to one another. In addition to simplifying assembly, this also simplifies maintenance work, for example.

[0005] In common multiple couplings, a coupling carrier often has a multitude of receptacles for interacting with different plug-in coupling components. This ensures maximum flexibility and adaptability when configuring a multiple coupling for a specific application. However, the number of different components also increases the risk of assembly errors. If ventilation or vent valves are to be provided, additional components are often required for their arrangement, and the space required increases.

[0006] The present invention is therefore based on the object of specifying a multiple coupling for media lines in which the risk of assembly errors is reduced and which ensures an advantageous arrangement of ventilation and venting valves while at the same time having a compact shape.

[0007] The aforementioned object is achieved in a generic multiple coupling for media lines according to the characterizing part of claim 1 in that the first coupling carrier has at least one fluid channel. The fluid channel has at least one first connection interface and at least one second connection interface. The second connection interface is arranged in the coupling carrier such that it extends at an angle to the first connection interface. For example, the angle is determined at the center axis of the fluid line at the first connection interface or the second connection interface.

[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. Each receptacle has fixing means, e.g. locking arms with locking projections, for holding, in particular in a form-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 receptacles for plug-in coupling parts. Particularly preferably, the multiple coupling has one plug-in coupling part for each receptacle of a coupling support.However, it is also intended that, depending on the intended use, only some of the receptacles of a coupling carrier are equipped with plug-in coupling parts.

[0010] Preferably, at least two corresponding plug-in coupling parts for the first two receptacles of the coupling carriers are made of brass or plastic. With a total of two receptacles per coupling carrier, 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. A plug-in coupling part made of brass or plastic preferably has a connection dome.

[0011] 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 rusting and / or screwing. The first coupling carrier and the second coupling carrier can in particular be connected to one another directly. 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 orientation to one another, whereby the media lines connected or connectable to the coupling carriers are correctly assigned to one another. It is also 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.

[0012] 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 an 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.

[0013] At least the first coupling carrier has, in addition to the first receptacle, at least one first fluid channel. The fluid channel has at least one first connection interface and at least one second connection interface. For example, the first fluid channel extends only between the first connection interface and the second connection interface. The course of the fluid channel in and / or on the coupling carrier is such that a first connection interface of the fluid channel extends at an angle, in particular orthogonally, to the second connection interface. The first connection interface extends, in particular, orthogonally to the second connection interface.

[0014] As a result, a valve, in particular a ventilation valve, can advantageously be arranged at the second connection interface while saving installation space - in particular in the thickness direction of the multiple coupling.

[0015] For example, the angle is in a range between 75° and 105°; preferably, the angle is approximately 90°. Advantageously, the central axis of the fluid channel at the first connection interface extends at an angle to the central axis of the fluid channel at the second connection interface. The fluid channel has at least one deflection along its extension between the first connection interface and the second connection interface, in particular a deflection corresponding to the angle, preferably a 90° deflection.

[0016] The first fluid channel extends at least partially, in particular completely, within the first clutch carrier. For example, the first fluid channel, in particular also the first connection interface and the second connection interface, are formed integrally with the first clutch carrier.

[0017] Preferably, the first connection interface is formed parallel to the joining direction of the first coupling carrier and the second coupling carrier.

[0018] For example, the first receptacle of the first coupling carrier is aligned parallel to the joining direction. Advantageously, the first connection interface and the first receptacle are aligned parallel to each other. For example, the first connection interface extends parallel to the joining direction from the connection area to the second coupling carrier. Preferably, the second connection interface is arranged in an imaginary plane to which the joining direction F is a plane normal.

[0019] 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%.

[0020] 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 multiple coupling according to the invention enables the filling and testing of the commercial vehicle axle prior to its actual assembly on the vehicle frame.

[0021] The invention has the advantage over the prior art that sealing planes and separation points are eliminated, thus reducing the risk of leakage. Furthermore, assembly effort is reduced, as fewer parts need to be assembled with respect to the first coupling carrier compared to prior art multiple couplings. Furthermore, manufacturing is simplified, as fewer individual parts need to be manufactured compared to prior art. The arrangement of valves is simplified, and the angled arrangement of the connection interfaces saves installation space.

[0022] According to a first embodiment of the multiple coupling, the first receptacle of the first coupling carrier is oriented parallel to the joining direction of the first coupling carrier and the second coupling carrier. A plug-in coupling part is thus inserted into the first receptacle parallel to the joining direction of the first coupling carrier and the second coupling carrier. The same applies to the first receptacle of the second coupling carrier. Preferably, the first connection interface of the first fluid channel is also oriented parallel to the joining direction of the first coupling carrier and the second coupling carrier.

[0023] For example, the first connection interface of the fluid channel is aligned parallel to the first receptacle. This allows contact to be made with the first connection interface from the same direction as the first receptacle, in particular with a plug-in coupling part inserted into the first receptacle. This simplifies line routing. The first connection interface and the plug-in coupling part inserted into the first receptacle of the first coupling carrier extend away from the second coupling carrier or the joining plane with the second coupling carrier. A further embodiment of the multiple coupling provides that the first coupling carrier has at least one second receptacle for a plug-in coupling part and the second coupling carrier has at least one second receptacle for a plug-in coupling part. Preferably, two further plug-in coupling parts are also included, so that a plug-in coupling part can be inserted into or inserted into each receptacle of each coupling carrier.is introduced.

[0024] Preferably, the second receptacles of the first coupling carrier and the second coupling carrier have a diameter that differs from the diameter of the first receptacles of the first coupling carrier and the second coupling carrier. This ensures that only the plug-in coupling part intended for it can be inserted into the respective receptacle.

[0025] The connection functionality of the multiple coupling can be improved in particular by providing, according to a further embodiment, that the first coupling carrier has at least one second fluid channel and / or at least one third fluid channel and / or at least one fourth fluid channel. Preferably, each of the existing fluid channels has a first connection interface and a second connection interface aligned at an angle, in particular at an angle of 90°, to the first connection interface. The angle between the first connection interface and the second connection interface is preferably the same for all fluid channels. For example, the angle lies in a range between 75° and 105°. Preferably, the angle is approximately 90°. In particular, each first connection interface is aligned orthogonally to the associated second connection interface of the fluid channel.

[0026] For example, the first connecting interfaces of three fluid channels are aligned parallel to one another, in particular in the same direction, and the second connecting interfaces of the three fluid channels are also aligned parallel to one another, in particular in the same direction. It is particularly preferably provided that at least one fluid channel has only a first connecting interface. For example, it is provided that at least one fluid channel ends on a rear side of a coupling carrier, e.g. the first coupling carrier. This allows, for example, ventilation into the space between the first coupling carrier and the second coupling carrier in the assembled state. The fluid channel has, for example, a first connecting interface and then opens into the rear side of the first coupling carrier.For example, the first connecting interfaces of three fluid channels are aligned parallel to one another, in particular in the same direction, and the second connecting interfaces of the three fluid channels are also aligned parallel to one another, in particular in the same direction. In a fourth fluid channel, only the first connecting interface is aligned parallel to the first connecting interfaces of the other three fluid channels. A second connecting interface is not present for the fourth fluid channel in this variant.

[0027] Preferably, at least or exactly one, at least or exactly two, at least or exactly three, or at least or exactly four of the existing fluid channels have a first connection interface and a second connection interface aligned at an angle, in particular at an angle of 90°, to the first connection interface. The angle between the first connection interface and the second connection interface is preferably the same for at least or exactly two, at least or exactly three, or at least or exactly four fluid channels. For example, the angle lies in a range between 75° and 105°. Preferably, the angle is approximately 90°.

[0028] In order to advantageously contact the first and second connection interfaces, a further embodiment provides that at least the first connection interface, in particular of the first fluid channel, has at least one locking collar or at least one connection dome. The locking collar is preferably designed such that it can be engaged behind by a locking means, for example a clamping ring or locking arm, in particular a substantially C-shaped one. The locking collar is preferably designed such that it can interact with a locking system disclosed in EP 2 759 757 B1, in particular with a holding part disclosed in Figs. 6 to 8 of the aforementioned document for fastening a coupling element disclosed in Fig. 1 of EP 2 759 757 B1, for example in the form of a connection dome.Preferably, at least two first connection interfaces have a locking collar and are designed to at least partially receive a coupling element (see, for example, Fig. 1 of EP 2 759 757 B1).

[0029] A connecting mandrel is designed, for example, for connecting to a media hose and preferably has a plurality of retaining projections. Preferably, each first connection interface of each existing fluid channel has at least one locking collar or at least one connecting mandrel or at least one connector, in particular for quick coupling. Furthermore, alternatively or additionally, the second connection interface, in particular of the first fluid channel, or of each existing fluid channel, is designed as a receptacle, in particular for a venting and / or venting valve.

[0030] The respective second connection interface is designed such that a ventilation and / or venting valve can be inserted and fixed in the receptacle. For this purpose, the respective second connection interface has, for example, an internal thread that is designed to interact with a valve, in particular a ventilation and / or venting valve. It is preferably provided that a ventilation and / or venting valve can be or is inserted into each of the second connection interfaces. As a result, the ventilation and / or venting valves are arranged in a space-saving manner in the side region of the coupling carrier, thereby saving installation space, in particular in the thickness direction.

[0031] According to a further embodiment of the multiple coupling, it is particularly preferred if the first coupling carrier has at least or exactly four fluid channels, and that each fluid channel has a first connection interface and a second connection interface aligned at an angle to the first connection interface. Furthermore, it is preferably provided that such a first coupling carrier has two receptacles, i.e., a first receptacle and a second receptacle for a plug-in coupling part. A plug-in coupling part is advantageously inserted into both receptacles. The second coupling carrier has, in particular, two corresponding receptacles with corresponding plug-in coupling parts.

[0032] Alternatively, it is preferably provided that at least three of the four fluid channels have a first connection interface and a second connection interface aligned at an angle to the first connection interface, and that a further fluid channel has a first connection interface.

[0033] To simplify connection of the fluid channels, it is preferably provided that the first connection interfaces of all four fluid channels are aligned parallel to one another, in particular in the same direction, preferably away from the second coupling carrier or a joining plane with the second coupling carrier. Preferably, the first connection interfaces of all four fluid channels are aligned parallel to the joining direction of the first coupling carrier and the second coupling carrier or parallel to the first receptacle and the second receptacle.

[0034] It is further preferably provided that three of the four second connection interfaces are aligned parallel to one another in the same direction and a further, second connection interface is aligned in a different direction. Preferably, the second connection interfaces of all four fluid channels are aligned parallel to one another, but it is provided that one of the second connection interfaces of a fluid channel is aligned opposite to the second connection interfaces of the remaining three fluid channels. All second connection interfaces are preferably each arranged in an imaginary plane to which the joining direction F is a plane normal. The second connection interfaces advantageously extend in the lateral region of the first coupling carrier.

[0035] It is further preferably provided that three second connection interfaces are aligned parallel to each other in the same direction.

[0036] All four fluid channels extend at least partially within the first clutch carrier. In particular, it is provided that all four fluid channels, in particular also all first and second connection interfaces, are formed integrally with the first clutch carrier.

[0037] In the design with four fluid channels, it has proven advantageous if at least two first connection interfaces have at least one locking collar for interacting with a C-shaped retaining ring or retaining part, in particular according to EP 2 759 757 B1 - as described above.

[0038] Alternatively or additionally, it is provided that at least two first connection interfaces have at least one connection dome.

[0039] Preferably, the two connection domes have a different diameter.

[0040] Furthermore, alternatively or additionally, it is provided that at least three, in particular at least four, second connection interfaces are designed to accommodate a valve, in particular a ventilation and / or venting valve. In particular, a ventilation and venting valve, in particular with at least one oil-separating filter fleece and at least one membrane, is arranged in at least three second connection interfaces, and a venting valve is arranged in at least one of the second connection interfaces. The membrane is preferably impermeable to water and permeable to vapor diffusion and is made, for example, from polytetrafluoroethylene (PTFE). The venting valve is preferably arranged in the second connection interface, which is aligned parallel to the other connection interfaces but in an opposite direction.

[0041] According to a further embodiment, which also has at least or exactly four fluid channels, it is advantageously provided that at least three second connection interfaces have a matching inner diameter. Alternatively or additionally, it is provided that at least two first connection interfaces have a matching inner diameter. Furthermore, alternatively or additionally, it is provided that at least two first connection interfaces have a connection dome.

[0042] When arranging a valve for venting in at least one second connection interface, it has proven advantageous if an inner sleeve made of metal, in particular brass, is pressed into at least one second connection interface, in particular into exactly one second connection interface. During the lifting and lowering movements of the valve, the inner sleeve prevents the inner circumference of the connection interface from becoming worn. Preferably, an inner sleeve made of brass is pressed into the second connection interface with the vent valve and surrounds the vent valve.

[0043] According to a further embodiment, two fluid channels have a first diameter, one fluid channel has a second diameter, and one fluid channel has a third diameter, and the first diameter, the second diameter, and the third diameter are different from one another. Thus, the fluid channels are adapted to the different requirements of the media being supplied.

[0044] To keep the plug-in coupling parts fixed in the receptacles, a further embodiment of the multiple coupling provides that at least the first receptacles and the second receptacles each have a plurality of locking arms, each with at least one locking projection. The locking arms are arranged such that they can deflect in the radial direction of the receptacles in order to engage the locking projections with a locking recess on a plug-in coupling part, in particular in a form-fitting or force-fitting manner. The locking arms are preferably aligned substantially parallel to the longitudinal or central axis of a receptacle.

[0045] Advantageously, the locking arms of the receptacles, which are opposite one another when the first coupling carrier and the second coupling carrier are in the assembled state, are designed such that they interact in the assembled state to prevent the release of inserted plug-in coupling parts for removal. The lengths of the locking arms are preferably coordinated with one another so that short locking arms in the first coupling carrier and long locking arms in the second coupling carrier, or long locking arms in the first coupling carrier and short locking arms in the second coupling carrier, are opposite one another. When the two coupling carriers are joined together, the long and short locking arms interact in such a way that none of the locking arms can move from its locking position with an inserted plug-in coupling part. The plug-in coupling parts are thus reliably fixed in their locking position.

[0046] A further embodiment of the multiple coupling provides that at least one plug-in coupling part, particularly on the side applied to the coupling carrier in the assembled state, has at least one connection dome and / or at least one valve, particularly a check valve or drain stop valve with backflow prevention, and / or at least one oil separator filter fabric and / or at least one membrane. The membrane is preferably impermeable to water and vapor diffusion and is made, for example, from polytetrafluoroethylene (PTFE). In this way, the plug-in coupling parts can be adapted to the requirements. Plug-in coupling parts with a connection dome are preferably inserted into all receptacles.

[0047] The invention further relates to a, in particular first, plate-like coupling carrier according to one of the above-described embodiments. Further advantageous embodiments of the invention will become apparent from the following description of the figures and the dependent subclaims.

[0048] They show:

[0049] Fig. 1 to Fig. 5 an embodiment of a first plate-like coupling carrier for a multiple coupling in different views, and

[0050] Fig. 6 an embodiment of a second plate-like

[0051] Coupling carrier for a multiple coupling in perspective view.

[0052] In the various figures of the drawing, identical parts are always provided with the same reference symbols.

[0053] 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.

[0054] Figs. 1 to 5 show an embodiment of a plate-like first coupling carrier 1 for a multiple coupling for media lines. Fig. 1 shows a perspective top view of the top side of the coupling carrier 1—facing away from a joining plane to the second coupling carrier 2—Fig. 2 shows a top view of the top side of the coupling carrier, Fig. 3 shows the underside of the coupling carrier 1—with the joining plane to a second coupling carrier 2—, Fig. 4 shows a first side view of the coupling carrier 1, and Fig. 5 shows a view of the coupling carrier 1 from an upper end face.

[0055] Fig. 6 shows an embodiment of a plate-like second coupling carrier 2, which can be joined to a first coupling carrier 1, for example according to Figs. 1 to 5, to form a multiple coupling. In the state shown in Fig. 6, a plug-in coupling part 3 is introduced into the second coupling carrier 2. For connection to plug-in coupling parts 3, the first coupling carrier 1 has a first receptacle 4 and the second coupling carrier 2 likewise has a first receptacle 5. The receptacles 4, 5 serve for inserting and fixedly holding plug-in coupling parts 3 - see also Fig. 1.

[0056] The first coupling carrier 1 and the second coupling carrier 2 are designed such that the plug-in coupling parts 3 of corresponding receptacles 4, 5 that can be arranged or are arranged in the receptacles 4, 5 can be coupled by joining the first coupling carrier 1 and the second coupling carrier 2.

[0057] 1 to 5, the first coupling carrier 1 has at least a first fluid channel 6a with a first connection interface 7a and a second connection interface 8a. The fluid channel 6a extends between the first connection interface 7a and the second connection interface 8a. The second connection interface 8a is aligned at an angle, here at an angle of approximately 90° to the first connection interface 7a and extends in the upper side region of the coupling carrier 1. In this exemplary embodiment, the first receptacle 4 of the first coupling carrier 1 and the first connection interface 7a of the fluid channel 6a are aligned parallel to the joining direction F of the first coupling carrier 1 and the second coupling carrier 2.

[0058] 1 to 5, the first coupling carrier 1 further comprises a second receptacle 9 and the second coupling carrier 2 further comprises a second receptacle 10 - see also Fig. 6. According to Fig. 6, no plug-in coupling part 3 is introduced into the second receptacle 10 of the second coupling carrier 2. In this exemplary embodiment, the first receptacles 4, 5 of the first coupling carrier 1 and of the second coupling carrier 2 have a different diameter than the second receptacles 9, 10 of the first coupling carrier 1 and of the second coupling carrier 2 in order to prevent the plug-in coupling parts 3 from being mixed up. Locking arms 11 with locking projections 12 are provided in the first and second receptacles 4, 5, 9, 10 in order to lock the plug-in coupling parts 3 in a form-fitting manner in the first and second receptacles 4, 5, 9, 10.

[0059] According to the embodiment of Figs. 1 to 5, the first coupling carrier 1 further comprises a second fluid channel 6b with a first connection interface 7b and a second connection interface 8b. Furthermore, a third fluid channel 6c with a first connection interface 7c and a second connection interface 8c and a fourth fluid channel 6d with a first connection interface 7d and a second connection interface 8d are provided.

[0060] The first connection interface 7a of the first fluid channel 6a and the first connection interface 7b of the second fluid channel 6b are essentially identical. The first fluid channel 6a and the second fluid channel 6b have the same inner diameter. The first connection interfaces 7a, 7b each have a locking collar 13, which is designed in particular to cooperate with a holding part according to EP 2 759 757 B1 (Figs. 5 to 7).

[0061] The second connection interfaces 8a, 8b, 8c of the first, second, and third fluid channels 6a, 6b, 6c are also identical and designed as a receptacle for a vent valve. For this purpose, the second connection interfaces 8a, 8b, 8c preferably have an internal thread for interacting with a valve, in particular a venting and / or venting valve. A venting and venting valve 21 is inserted into each of the second connection interfaces 8a, 8b, 8c and secured there—see Fig. 5. The third fluid channel 6c has a different diameter than the first and second fluid channels 6a, 6b and also a different diameter than the fourth fluid channel 6d. The first connection interface 7c of the third fluid channel 6c is designed as a connecting mandrel that extends substantially parallel to the joining direction F of the first coupling carrier 1 and the second coupling carrier 2.The first connection interface 7d of the fourth fluid channel 6d is also designed as a connecting mandrel with a different diameter than the diameter of the connecting mandrel of the first connection interface 7c of the third fluid channel 6c. The connecting mandrel of the first connection interface 7d of the fourth fluid channel also extends parallel to the joining direction F. The second connection interface 8d of the fourth fluid channel 6d is designed as a receptacle for a vent valve. A vent valve 19 is arranged in the second connection interface 8d of the fourth fluid channel 6d. Preferably, a brass sleeve, in which the vent valve 19 is arranged, is introduced into the second connection interface 8d of the fourth fluid channel 6d.

[0062] In this exemplary embodiment, the first connection interfaces 7a, 7b, 7c, 7d are aligned substantially orthogonally to the second connection interfaces 8a, 8b, 8c, 8d. The second connection interfaces 8a, 8b, 8c, 8d are arranged in imaginary planes, to which the joining direction F is a plane normal. As a result, the second connection interfaces 8a, 8b, 8c, 8d are arranged in lateral regions of the first coupling carrier 1, resulting in advantageous space savings.

[0063] The first connection interfaces 7a, 7b, 7c, 7d of all four fluid channels 6a, 6b, 6c, 6d are aligned parallel to one another, in particular parallel to the joining direction F. All four first connection interfaces 7a, 7b, 7c, 7d are also aligned in the same direction, namely extending away from an upper side of the first coupling carrier 1. Three of the four second connection interfaces 8a, 8b, 8c are also aligned parallel to one another and in the same direction, namely in a first, upper lateral direction of the first coupling carrier 1. The second connection interface 8d of the fourth fluid channel 6d is also aligned parallel to the other three second connection interfaces 8a, 8b, 8c, but in an opposite direction - in a lower lateral region of the first coupling carrier 1.

[0064] All four fluid channels 6a, 6b, 6c, 6d run at least partially within the first clutch carrier 1. All four fluid channels 6a, 6b, 6c, 6d are formed integrally with the first clutch carrier 1.

[0065] The three second connecting interfaces 8a, 8b, 8c of the first, second, and third fluid channels 6a, 6b, 6c have a matching inner diameter. With respect to the fluid channels 6a, 6b, 6c, 6d, only the first and second fluid channels 6a, 6b have a matching diameter; the diameter of the third fluid channel 6c differs from that of the first two fluid channels 6a, 6b. Furthermore, the diameter of the third fluid channel 6c also differs from that of the fourth fluid channel 6d and that of the first two fluid channels 6a, 6b.

[0066] The first coupling carrier 1 has two receptacles 14 into which threaded nuts 18 are inserted to screw the first coupling carrier 1 to the second coupling carrier 2. The second coupling carrier 2 has corresponding recesses 15. In order to lock the first coupling carrier 1 to a second coupling carrier 2, the first coupling carrier 1 also has four locking arms 16 that extend essentially parallel to the joining direction F of the first coupling carrier 1 and the second coupling carrier 2. The locking arms 16 preferably have resilient locking tongues.
