The invention relates to a plug-in module for arrangement in a hybrid module of a motor vehicle, a hybrid module for a motor vehicle for coupling a

Internal combustion engine and a transmission with the plug-in module according to the invention and a drive train for a motor vehicle with a

Internal combustion engine and a hybrid module according to the invention. Furthermore, the invention relates to a method for assembling a

Drive train according to the invention.

Currently available hybrid modules by coupling an internal combustion engine to a drive train of a vehicle, an electric motor operation with a

Combustion engine operation usually include an electric motor, a disconnect clutch, their actuation system, bearings and housing components that connect the three main components to a functional unit.

The electric motor allows electric driving, performance gain for

Internal combustion engine operation and recuperation. The separating clutch and their

Actuation system ensure the coupling or uncoupling of the

Combustion engine. If a hybrid module is combined with a dual clutch in such a way that the hybrid module is located in the torque transmission direction between the internal combustion engine and the transmission, in the vehicle the internal combustion engine, the hybrid module, must have the double clutch with its

Actuation systems and the transmission are arranged behind or next to each other.

Such a positioned hybrid module is also referred to as a P2 hybrid module. However, such an arrangement very often leads to considerable installation space problems that also influence or impede the assembly.

From DE 10 2009 059 944 A1 a hybrid module is known, which the

Disconnect coupling within a rotor of an electric machine.

Part clutches of a dual clutch device are axially offset next to the Rotor of the electric machine and thus also next to the separating clutch

arranged. The partial clutches are nested radially. The actuating systems for the individual clutches are arranged axially offset next to these clutches.

DE 10 2007 008 946 A1 teaches a multiple clutch for a vehicle with a hybrid drive. In this hybrid module, two friction clutches are arranged within the space enclosed by the rotor of the electric machine. The available space in the hybrid module is largely determined by the electrical machine used and their laminated core.

On this basis, the present invention seeks to provide a plug-in module, a hybrid module and a drive train for a motor vehicle available, which combine a small space with the possibility of easy installation and compliance with low tolerances.

This object is achieved by the plug-in module according to claim 1, by the hybrid module according to the invention according to claim 8, by the

Drive train according to claim 9 and by the invention

The inventive method for assembling the drive train according to claim 10 solved. Advantageous embodiments of the plug-in module are specified in the dependent claims 2-7.

The features of the claims may be combined in any technically meaningful manner, for which purpose the explanations of the following description as well as features of the figures may be consulted which comprise additional embodiments of the invention. The directions axially and radially refer to the common axis of rotation of said

Aggregates. Thus, the axial direction is oriented orthogonal to friction surfaces of the slats. The invention relates to a plug-in module for arrangement in a hybrid module of a motor vehicle, comprising a substantially rotationally symmetrical

Plate carrier and at least two coupling devices, in particular a Disconnect clutch and at least one starting clutch, wherein the

Coupling devices each having at least one disk set, each of which at least one lamella is fixedly connected to a driving means, in particular a toothing, of the disk carrier. Of the

The plate carrier essentially has the shape of a hollow annular cylinder composed of two rotationally symmetrically arranged hollow cylinders. It is envisaged that the entrainment means are arranged in the radially delimited by the disk carrier space on at least one of the radially spaced and facing sides of the hollow annular cylinder.

The coupling devices can be configured as wet clutches.

The disconnect device is in particular connected to an input side of the hybrid module. Preferably, in addition to the separating clutch, two partial coupling devices of a dual clutch device are provided, the disk sets of which are connected to an output side of the hybrid module.

The torque-resistant application of a blade of a disk set to a driving device can allow an axial displacement. For this purpose, the entrainment device is preferably designed as a spline. A hollow annular cylinder is a body whose inner hollow cylinder forms an outer side which is radially opposite the inner side of the outer hollow cylinder.

Thus, as a subassembly or subassembly, an outside one

Hybrid module testable plug-in module provided, which at

Inclusion of three coupling devices also called triple clutch.

The advantage of this plug-in module lies in particular in the high dimensional accuracy or the low mounting tolerances in the mounted state due to the fact that almost all assembly steps and surveying operations that are necessary for the production of the plug-in module outside a rotor of an electric machine of a hybrid module, for which the plug-in module is provided, so that reliably all geometric relationships of

Coupling devices can be adjusted to each other and with respect to the plate carrier to the respective desired actual size. In addition, adjusting operations on the coupling devices can thereby be made simpler or more accurate.

Furthermore, the plug-in module according to the invention, this allows for

to manufacture different hybrid modules or rotor carrier, wherein only the contour of the plug-in module is ready to customize the rotor carrier to provide a unit as a so-called "Add in" available, which can be integrated anywhere and time independent in a rotor carrier.

In particular, it is provided that Lammellenpakte of two

Coupling devices are arranged radially offset from one another and the

Carrier devices for connection to at least one blade of a

Disc packs are arranged in the radially delimited by the disk carrier space at the two radially spaced and facing inner sides of the two hollow cylinder of the hollow annular cylinder. That means that the

Mitnehmereinrichtungen are arranged in a radially delimited by the disk carrier hollow annular cylinder space at radially opposite inner sides, where the disk sets are rotatably connected, so that the

Lamella packages are connected to opposite inner sides. In a further preferred embodiment, a further coupling device is arranged axially adjacent to one of the two coupling devices, of which likewise at least one lamella is arranged on a driver device on the inside of the hollow cylinder, on which at least one lamella of the

Disc packs of the axially adjacent coupling device is arranged.

This means that the disk set of the third coupling device has such a distance from the common axis of rotation of the coupling devices that the disk sets of the axially adjacent coupling devices overlap in the radial direction. The fins of both disk sets are rotatably connected on the same side of the same hollow cylinder with the local entrainment facilities.

Despite the arrangement of three disc packs, the invention provides

Slide-in module has the advantage of easy handling during assembly, in particular on the assembly line, and when used in a rotor carrier of a hybrid module to be generated, so that the assembly and assembly can be done in a simplified manner and not susceptible to interference manually or automated. In particular, it is provided that the disk packs of a first

Partial coupling device and a second partial coupling device a

Double clutch device are arranged on the inside of the outer hollow cylinder and the disk set of a separating clutch are arranged on the outside of the inner hollow cylinder. On these pages of said hollow cylinder, the slats of the disk packs are realized there on entrainment devices

connected.

Preferably, the entrainment devices are designed as toothings which have a plurality of teeth distributed on the respective circumference and having axially extending teeth. In this case, at least one support element can be integrated in this toothing, which serves to axially on a coupling device

applied actuating force to actuate the respective coupling device. Thus, e.g. such a support element to be a gap in the toothing, on which axially supports a counter-plate of a plate pack or can support.

Formed to form a mechanical unit that simplifies the assembly operations, it is provided that the hollow annular cylinder of the disk carrier has at least one front-side connecting element which radially connects the two hollow cylinders of the hollow annular cylinder.

To a torque of a rotationally driven component on the

To transfer disk carrier or in the reverse direction is provided that the disk carrier at least one on its radial outer side

Having torque transmission element, for transmitting a torque from the plate carrier to a radially connected thereto component. In this way, a torque can be transmitted from the disk carrier to a rotor carrier of a hybrid module surrounding it radially, and in the opposite direction. The torque transmission element may also be a toothing, which allows an axial insertion of the disk carrier or the entire plug-in module in a rotor carrier. The disk carrier can be made in one or more parts, in particular two parts, wherein it has an inner part and an outer part and a mechanical

Connection of the inner part and the outer part is carried out at a radial position between the radial positions of the inner hollow cylinder and the outer hollow cylinder. Thus, in particular a front-side connecting element may be divided into two, wherein an outer part of the front-side connecting element is arranged on the outer part of the disk carrier or is executed by this, and an inner part of the front-side connecting element is arranged on the inner part of the disk carrier or is executed by this, and a mechanical connection between the inner part of the front-side connecting element and the outer part of the front-side connecting element is executed. This mechanical

Connection can be carried out by a variety on the circumference of the connection area realized screw or rivet or clinch or welded joints. The multi-part design of the disk carrier makes it possible to produce the disk carrier with simpler or more cost-effective production methods.

In addition, the multi-part of the disk carrier opens up the possibility of a different mounting sequence of the disk carrier in a rotor carrier of a hybrid module, since initially one of the parts inner part and outer part can be arranged in or on the rotor carrier, possibly coupling devices in the rotor of the electric

Machine of the hybrid module surrounding space can be used and only then the other part can be used, which was possibly previously equipped with a disc pack another coupling device.

Another aspect of the present invention is a hybrid module for a

Motor vehicle for coupling an internal combustion engine and a

Gear, which comprises a plug-in module according to the invention and an electrical machine whose rotor is rotatably connected to a rotor carrier comprises. The rotor carrier is rotatably coupled to the plug-in module, so that from the rotor applied electrical machine torque to the plug-in module is transferable. For actuating axially arranged side by side

Coupling devices may be an axially acting actuator, which is mechanically connected to a pressure plate of one of the two coupling devices

is connected, through the disk set of axially adjacent

Pass coupling device to implement through this disc pack through an axial motion transmission. The this lamella package

comprehensive coupling device is associated with an actuating system, which may be located within or outside of the radially and axially enclosed by the plate carrier space. Accordingly, a can also

Actuating system, which is mechanically coupled to the axially overlapping the disk assembly actuator, inside or outside the radially and axially enclosed by the disk carrier space. The aforementioned actuation systems can the two partial coupling devices of a

Be associated with dual clutch device.

The entrainment means preferably provided as toothing are arranged for transmitting the torque to the two axially juxtaposed coupling devices with equal radial distances to the common axis of rotation, but in one of the axially adjacent coupling devices, the lamellae, not with the

Co-driver devices of the disk carrier cooperate, have a smaller radial extent than that of the adjacent coupling device, since between the radial end faces of these disks and the driver, the axially acting actuator is passed through the disk set. An actuating system for the separating clutch can be arranged axially on the two opposite sides of the actuator systems mentioned opposite sides of the disk carrier, in which case a this actuating system associated

Actuator axially an end-side connecting element of the hollow

Passes through annular cylinder of the disk carrier.

The rotor carrier is preferably at least partially complementary in terms of its shape designed to the outer shape of the disk carrier, so that the rotor carrier forms a recess in the form of a hollow cylinder, in which the Insert module according to the invention can be used and is preferably positively connected to the rotor carrier, for example by means of external toothing, which cooperates with an internal toothing of the rotor carrier rotatably. That means that the

Rotor carrier radially surrounds the plate carrier at least partially.

Due to the separately manufacturable plug-in module, a modular assembly of the hybrid module can take place.

Likewise, the present invention relates to a drive train for a motor vehicle with an internal combustion engine and a hybrid module according to the invention and with a transmission, wherein the hybrid module with the

Internal combustion engine and the transmission mechanically over

Coupling devices of the plug-in module in the hybrid module can be connected or connected. In addition, according to the invention, a method for assembling a drive train according to the invention is provided, in which a

Is provided according to the invention plug-in module, a rotor carrier of a hybrid module to be produced is provided, an output shaft of a

Internal combustion engine is provided, the plate carrier of the

Plug-in module is used in the space radially enclosed by the rotor carrier space, and a non-rotatable mechanical connection between the output shaft and one of the coupling means of the plug-in module and a non-rotatable mechanical connection between the plate carrier and the rotor carrier is realized. In this case, the steps of realizing a respective rotationally fixed connection are not necessarily to be carried out in the stated order.

Before realizing a non-rotatable mechanical connection between the output shaft and one of the coupling devices of the plug-in module, a housing part of the hybrid module to be provided with the plug-in module can be rotatably mounted on the output shaft.

An actuator or an actuating system for actuating one of

Coupling devices, in particular a separating clutch, can be arranged in or on a wall of the housing part. The rotor carrier on which the rotor of the electric machine is arranged rotationally fixed relative to the rotor carrier, can be arranged on a portion of the housing part, so that the rotor carrier is rotatable relative to the housing part. During assembly, the plug-in module is housed with it

Disconnect coupling and another coupling device, such. one

Starting clutch, axially inserted into the rotor carrier. An intermediate shaft coupled to the plug-in module or means, e.g. is coupled to an input side of the clutch, is rotatably coupled to the output shaft of the internal combustion engine.

The above-described invention will be explained in detail in the background of the relevant technical background with reference to the accompanying drawings, which show preferred embodiments. The invention is not limited by the purely schematic drawings in any way, it being noted that the embodiments shown in the drawings are not limited to the dimensions shown. It is shown in Figure 1: a hybrid module according to the invention in partial section,

2 shows a plate carrier of a first embodiment in partial section,

3 shows a plate carrier of a second embodiment in partial section,

4 shows a plate carrier of a third embodiment in partial section. An intermediate shaft 32 of the hybrid module 10 coupled to the hybrid module 10 shown in FIG. 1 is coupled or connected to an output shaft of an internal combustion engine not shown, for example via a damper (not shown here), such as a dual mass flywheel.

The output side of an input side 1 1 of the hybrid module 10 representing intermediate shaft 32 is rotatably coupled to an outer disk carrier 54 of a separating clutch 50. Slats of the disk set 51 of the separating clutch 50 are in an annular cylinder space 91 which is formed by a plate carrier 90, arranged here, namely here on the outer side 94 of a first hollow cylinder 93 of the disk carrier 90th

The disk carrier 90 has a front-side connecting element 1 10, with which the first hollow cylinder 93 is radially coupled to a second hollow cylinder 95. On the inside 96 plate packs 71, 81 of a first

Partial coupling device 70 and a second partial coupling device 80, which together form a dual clutch device 60, arranged.

An inner disk carrier 74 of the first partial clutch device 70 is to

configured to transmit torque from the disk set 71 of the first part clutch device 70 to a first transmission input shaft, not shown here.

An inner disk carrier 84 of the second partial clutch device 80 is configured to transmit a torque from the disk set 81 of the second partial clutch device 80 to a second transmission input shaft (not illustrated here). The two inner disk carrier 74,84 form the output side 12 of the hybrid module 10. On the outer side 94 of the first hollow cylinder 93 as well as on the inside 96 of the second hollow cylinder 95 entrainment devices 100, preferably in the form of gears, arranged in a form-fitting manner with lamellae of the disk sets 51, 71, 81 of the separating clutch 50, the first

Partial coupling device 70 and the second partial coupling device 80

interact.

The first hollow cylinder 93 and the second hollow cylinder 95 of the disk carrier 90 are arranged coaxially with each other. The disk carrier 90 has on the outer side 94 of the first hollow cylinder as well as on the inner side 96 of the second hollow cylinder 95 each have a support element 101, here in the form of a notch or groove. This support element 101 serves to receive and axial support of the counter plate 73 of the first

Partial coupling device 70 on the inside 96 of the second hollow cylinder 95 and the inclusion and axial support of the counter-plate 53 of the separating clutch 50 on the outer side 94 of the first hollow cylinder 93, when the respective disk packs 51, 71 are axially loaded by the respective actuating systems 52, 72 and are supported on the counter plates 53, 73.

It can be seen that an axially acting actuating element 83 for actuating the second partial coupling device 80 extends axially through the disk set 71 of the first partial coupling device 70.

An actuator 52 for operating the disconnect clutch 50 is provided on an axial side of the hybrid module 10 facing the internal combustion engine in a state where the hybrid module 10 is installed in a power train of a hybrid vehicle. Actuators or actuation systems 72, 82 for actuating the first part-coupling device and the second one

Partial coupling device 80 are provided on one side of the hybrid module 10, which in a state in which the hybrid module 10 in the drive train of

Hybrid vehicle is installed facing the transmission. This means that the actuator or operating system 52 for actuating the separating clutch 50 has an actuating direction which is directed in an opposite direction with respect to the actuating direction of the actuating systems 72, 82 or actuators for actuating the first partial clutch device 70 and / or the second partial clutch device 80 is.

The plate carrier 90 for supporting lamellae of disc packs 71, 81 of the first partial clutch device 70 and the second partial clutch device 80 is considered to be rotatable relative to a rotor carrier 30 of the hybrid module 10

Arranged arrangement of a rotor 22 of an electrical machine 20 separate component.

The rotor carrier 30 and the plate carrier 90 are over

Torque transmission elements 120 such rotatably connected or coupled to each other such that a rotation of the rotor carrier 30 causes rotation of the disk carrier 90. The torque transmitting member 120 may be realized by, for example, a milling, a screwing, a boring, a pinning, or the like. The disk carrier 90 is rotatably arranged in a space formed by the rotor carrier 30 space on the rotor carrier 30.

The rotor carrier 30 serves to receive or arrange one at the radial

Inside a stator 21 of an electric machine 20 arranged rotor 22. The rotor 22 and the rotor carrier 30 and the plug-in module 40 are all arranged coaxially on a common axis of rotation 1 substantially.

The rotor arm is supported via roller bearings 140 on a housing part 31, which in turn is supported radially on the intermediate shaft 32. Due to the design of the rotor carrier 30 and the plate carrier 90 as

separate components can be a separating clutch 50 and the

Anfahrkupplungseinnchtungen, here designed as a partial coupling devices 70,80, exhibiting insertion module 40 can be created, which can be pushed axially in a simple manner in the rotor support 30 of the hybrid module 10, which allows a modular assembly of the hybrid module 10.

When assembling the hybrid module 10 in the drive train or installing the hybrid module 10 in the drive train, the housing part 31 is mounted on an output shaft of the internal combustion engine such that the output shaft is rotatable relative to the housing part 31. An actor or a

Actuation system 52 for actuating the disconnect clutch 50 is disposed in a wall of the housing part 31. The rotor carrier 30, on which the rotor 22 of the electric machine 20 is arranged so as to be non-rotatable relative to the rotor carrier 30, is mounted on a portion of the housing part 31 such that the rotor carrier 30 is rotatable relative to the housing part 32. The plug-in module 40 with the disconnect clutch 50 and the partial clutch devices 70,80 is inserted into the rotor carrier 30 such that the intermediate shaft 32 of the plug-in module 40, which is coupled to an input side of the disconnect clutch 50, or rotatably coupled to the output shaft of the internal combustion engine or is connected. The Lamellenträger90 is connected to the rotor carrier 30 to transmit torque. As can further be seen from FIG. 1, the hybrid module 10 comprises radially between the housing part 31 and the rotor carrier 30, which is partially coaxial with the rotor

Housing part 31 extends, a spacer element 150, which is also referred to as a spacer. This spacer element 150 lies with its radial

Inner side 151 on the radial outer side of the housing part 31 and is supported there radially. In this case, the spacer element 150 blocks an axial movement of the rolling bearing 140, which also between the rotor carrier 30 and the

Housing part 31 is arranged and axially supported on the spacer element 150 opposite side on a shoulder of the housing part 1. At the rolling bearing 140 axially opposite side is located on the

Spacing element 150 to a fixing element 170, which is formed here in the form of a special nut. The internal thread 171 of this special nut on an external thread 172 of the housing part 31st The fixing element 170 or the

Special nut has circumferentially distributed engagement holes 163 in the form of a special tool can be inserted to rotate the fixing element and thus move axially, and thus the distance between the

Adjustment element 170 and the rolling bearing 140. Accordingly, an axial bias can be generated in the spacer element 150, so that the spacer element 150 presses axially against the roller bearing 140 and against the fixing element 170 like a spring. This ensures the axial position of the

Rolling bearing 140.

Between the spacing element 150 and the rotor carrier 30, a further rotation bearing 160 is arranged, which in the embodiment shown here is a needle bearing. This rotary bearing 160 thus serves the further radial

Supporting the rotor carrier 30 on the housing part 31, namely by introducing radial forces in the rotary bearing 160 and from there to the

Spacer element 150, which is supported radially on the housing part 31. In the embodiment shown here, however, this is not the only one

Function of the spacer element 150, but it also serves to supply or adjustment of a lubricant volume flow in the space radially enclosed by the plug-in module 40 in which the coupling devices 50,70, 80 are located. For this purpose, the spacing element comprises a Through hole 180, which is part of the flow path 181 of the lubricant. This through-opening 180 is aligned in the radial direction with a passage 190 in the housing part 31 arranged on the radially outer side of the spacing element 150, and a passage 191 in the rotor support 30 arranged on the radially inner side of the spacing element 150, these two passages 190, 191 likewise being one Form part of the flow path 181. By the

Dimensioning of the passage opening 180 and the positioning of the

Spacing element 150, the inside diameter of the flow path 181 and thus the volume flow of a lubricant to be supplied can be adjusted.

Each of the axially adjacent coupling devices 70,80 is associated with a pressure element 85,86. The pressure element 75 of the first

Clutch device 70 is supported axially directly or directly on the

Disc pack 71 of the first part clutch device 70 from.

The pressure element 85 of the second partial clutch device 80 is supported indirectly on the disk set 81 of the second partial clutch device 80, namely here via the axially acting actuating element 83, which leads through fins of the disk set of the first partial clutch device 70.

Each of the two partial coupling devices 70,80 is also associated with a plate spring 76,86. These disk springs 76, 86 are supported by their respective radially outer edge 200 on the inside 96 of the second hollow cylinder 95 of the disk carrier 90. For this purpose, the plate carrier 90 at these points stepped elements 97.

The radially inner edge 201 of a respective plate spring 76, 86 acts axially against a respective pressure element 75, 85. A respective pressure element 75,85 is mechanically in communication with a respective actuating system 72,82 of the two partial coupling devices 70,80.

When such an actuation system 20, 82 is actuated, a force is transmitted axially to the respective pressure element 75, 85, which directly or indirectly transmits the axial force to a respective plate pack 71, 81. Such are the

Slats of the disk set 71, 81 pressed together and it can be transmitted torque with the respective part clutch device 70,80. In this respect one Partial coupling device 70,80 to be opened again, the operation of the respective actuation system 72,82 is terminated. A respective plate spring 76,86 now causes an axial return movement of the respective pressure element 75,85, so that the lamellae of the disk set 71, 81 can separate from each other.

Figure 2 shows the plate carrier 90 as a one-piece component. In particular, the driver device 100 can be seen, which is arranged on the outer side 94 of the first hollow cylinder 93 and also on the inner side 96 of the second hollow cylinder 95. The two hollow cylinders 93,95b are frontally over the

Connecting element 1 10 mechanically connected.

However, the disk carrier 90 can also be designed as a timed component, as can be seen from FIGS. 3 and 4. In the case of the two-part component is provided as mechanical Verbindungl 32 between an inner part 130 and an outer part 131 as a mechanical connection 132, a parting line of the two individual parts adjacent to the separating clutch 50, as shown in Figure 3. This parting joint or mechanical connection 132 may, for example, a

Be welded joint.

Figure 4 shows a further alternative of the structural design of the

Disk carrier 90, in which the inner part 130 and the outer part 131 of the

Slat carrier 90 axially overlap each other and with several

Screw connections or with one or more welded joints as a mechanical connection 132 are fastened together. FIGS. 5, 6 and 7 show different embodiments of the supports of the disk springs 76, 86 on the disk carrier 90.

It can be seen from these 3 figures that an axial opening 87 in the axially acting actuating element 83 of the second partial coupling device 80 has a larger radial extent or a larger diameter than the outer diameter of the two plate springs 76, 86. This allows for already mounted axially acting actuator 83, the possibility of subsequent use of the plate springs 76,86 in the plate carrier 90th Figure 5 shows that the plate spring 76 of the first part clutch device and the plate spring 86 of the second part clutch device 80 each at a

stepped element 97 of the plate carrier 90 or on the inside 96 of the second hollow cylinder 95 are applied and are supported there axially.

FIG. 6 shows an alternative embodiment, in which the plate spring 86 continues to be axially supported only on a step-shaped element 97, but the plate spring 76 is supported on a support ring 98, which in turn is supported axially on a step-shaped element 97.

The embodiment according to FIG. 7 differs from the embodiment shown in FIG. 6 in that, instead of the bearing ring 98, a retaining ring 99 is arranged, on which the radially outer edge 200 of the disc spring 76 is axially supported.

In the figures 8 and 9 is a section of the invention

Hybrid module shown, wherein Figure 9 illustrates the relevant area even more enlarged.

It can be seen here that in an axial end region 300 of the disk carrier 90 this projecting from its second hollow cylinder 95 radially outwardly

Form elements 301, so-called fingers having. This radially outward

protruding mold elements 301 penetrate the rotor carrier 30 in radial

Direction, namely by arranged for this purpose recesses 303 in the rotor support 30, which in particular have the form of slots. These

Recesses 303 are incorporated in the embodiment shown here in the end face 304 of the rotor carrier 30. Such can be in a simple and

Space-saving manner transmit torque between the rotor carrier 30 and the plate carrier 90 and the insertion module 40 formed therewith. In order to secure the axial position of the disc carrier 90 with respect to

Rotor carrier 30 is on the radially inner side of the rotor carrier 30 a

Secured securing element 305, which is radially embedded in the rotor carrier 30 and blocked by an axial abutment on the plate carrier 90, an axial displacement of the plate carrier 90 and consequently of the plug-in module 40. In the embodiment shown here it is not yet the only element which blocks an axial displacement, but also on the first hollow cylinder 93 of the disk carrier 90 between the radial inner side and the rotor support 30 is another element for blocking the translational degree of freedom

Lamellenträgers 90 arranged, namely here a spring ring 306 which is arranged in a groove 309 in the rotor carrier 30.

As a further constructive element for the positive transmission of

Torque between the rotor carrier 30 and the plate carrier 90 is a

Pass pin 307 provided in the front-side connecting element 1 10 of the

Slat support 90 and rotor arm 30 inserted.

For the purpose of realizing a structurally simple operation of the illustrated

Disconnect 50 is in the rotor arm 30 as well as in the frontal

Connecting element 1 10 at least one passage opening 308, preferably a plurality of such passage openings 308, provided by the one

Clutch actuating element 310 passes through to act on the fins of the separating clutch 50 with an actuating force.

FIG. 10 shows a further detail of a hybrid module according to the invention, namely here in particular the separating clutch 50, which is likewise located within the

Lamellenträgers 90 is arranged. It can be seen that the plate carrier 90 rests with its radial inner boundary on the rotor carrier 30. To secure the axial position of the disk carrier 90 and the thus equipped

Slide-in module 40 with respect to the rotor carrier 30 is a locking element, here in the form of the illustrated spring ring 306, disposed between the rotor carrier 30 and plate carrier 90.

In the illustrated position of the spring ring 306, in which he has a larger

Diameter than the rotor carrier 30, the spring ring 306 is free of stress and extends to the contour shown in dashed lines. After mounting the spring ring 306 on the rotor support 30 and before the axial insertion of the

Disk carrier 90 and the insertion module 40 equipped therewith in the

Rotor carrier 30, the spring ring 306 consequently represents an axial blockage against the insertion process. In order to enable insertion, axially extending through openings 400 are formed in the two inner disk carriers 74, 84 of the first partial clutch device 70 and the second partial clutch device 80. Such

Through opening 400 is also in the outer disk carrier 54 of the

Disconnect 50 is formed. The passage openings 400 are arranged such that they can be axially aligned with one another, as shown in FIG.

This allows the axial insertion of a tool 401 in the

Through openings 400. With the tool, the radially outstanding

Spring ring 306 are moved into the rotor carrier 30 to allow unhindered insertion of the disk carrier 90 in the rotor carrier 30.

Preferably, a plurality of uniformly distributed through openings 400 are present in the inner disk carriers or the outer disk carrier, which allow the simultaneous axial engagement of a plurality of tools 401.

Further assistance in inserting the disk carrier 90 into the rotor carrier 30 is effected by a section with an at least partially oblique course 403 on the disk carrier 90. This section 403 is arranged between the inner, first hollow cylinder 93 of the disk carrier 90 and the substantially perpendicularly extending end-side connecting element 1 10. This oblique area or there provided rounding on the plate carrier 90 causes when inserting the plate carrier 90 in the rotor carrier a wedge effect on the radially projecting spring ring 306 so that it is pushed away during the insertion movement of the disc carrier 90 in the rotor carrier 30 to axially inside.

With the plug-in module proposed here and the thus produced

Hybrid module units are provided, which can be mounted in a simple and manual as well as automated manner with low tolerances. LIST OF REFERENCE NUMBERS
