The present invention relates to a multi-clutch device for a hybrid module connected to an internal combustion engine and provided for vehicles such as, for example, passenger cars, lorries or other commercial vehicles. Further, the present invention relates to a hybrid module itself having a multi-clutch device.

The hybrid module usually includes a connection device for mechanical connection of an internal combustion engine; a separable clutch enabling torque to be transmitted from the internal combustion engine to the hybrid module and separating the hybrid module from the internal combustion engine; electric machines for generation of drive torque using rotors; and a double clutch device enabling transmission of torque from the electric machine and/or from the split clutch to the power train. The double clutch device includes a first partial clutch and a second partial clutch. Each of the respective deployed clutches is assigned one actuating system.

The electric machine enables electric driving, increased power for combustion engine mode, and regenerative braking. A detachable clutch and its actuation system provide for engagement or disengagement of a combustion engine.

If the hybrid module is integrated into the power train together with the double clutch in such a way that the hybrid module is disposed between the combustion engine and the transmission in the direction of transmission of torque, in the vehicle the combustion engine, the hybrid module, the double clutch with its own operating systems, and Transmissions must be arranged one after the other or next to each other. However, this arrangement sometimes causes mounting space problems.

Due to the use of multiple actuation systems for opening and engaging the individual clutches, forces from multiple locations, in most configurations having different directions and/or magnitudes, are introduced into each multi-clutch device or into each hybrid module. . Thus, depending on the respective operating state of the individual clutches, very different load-carrying patterns of the clutches or connected device assemblies can occur, perceptible in wear phenomena.

In this case, the electric machine is connected with the clutch device by means of a chain drive. The clutch assembly includes a center bearing disposed in an area extending axially from the shaft area, which center bearing supports the clutch device as well as the separable clutch. The center bearing is designed as a double-row angular contact ball bearing for axial and radial forces.

A German patent application with Korean Intellectual Property Office Application No. 102016203384.0, which has not been published as prior art, discloses a clutch assembly for a power train of a vehicle including a hybrid drive unit, and the electric machine of the hybrid drive unit is a clutch assembly through a belt drive. connected with The clutch assembly includes a first clutch and a second clutch, each of which includes rotational members that are rotatably separable from each other, the first rotational member of the first clutch and the first rotational member of the second clutch. , and coupled to rotate integrally with a central bearing disposed on the shaft region of the first rotating member of the second clutch. The center bearing is used as the axial and radial bearing of the first rotating member.

DE 10 2009 002 805 A1 teaches a parallel hybrid drive for vehicles with a vehicle transmission with a variable transmission ratio. The parallel hybrid drive also includes an electric machine and a combustion engine. An electrical machine may be connected to the transmission output shaft via a frictionally coupled shifting member. In this case, the rotational axis of the electric machine extends coaxially with the output shaft of the combustion engine and the input shaft of the transmission.

WO 2008/052909 A1 discloses a power train for a hybrid vehicle for mechanically coupling an electrical machine and a combustion engine by means of a clutch, wherein the clutch selectively connects the combustion engine with the electrical machine selectively entirely or electrically. completely disconnected from the machine. In this case, the rotational axis of the electric machine extends coaxially with the output shaft of the combustion engine and the input shaft of the transmission.

An object of the present invention is to provide a multi-clutch device with a low installation space requirement and a long useful life, and a hybrid module for automobiles equipped with the multi-clutch device.

The above object is solved through the present multi-clutch device according to claim 1 and the present hybrid module according to claim 9.

Preferred embodiments of the present multi-clutch device are specified in the dependent claims 2 to 8. A preferred embodiment of the hybrid module is specified in dependent claim 10 .

The features of the claims may be combined in their own technically meaningful type and manner, to which features in the following description and drawings including complementary features of the present invention may be added.

The concepts of radial and axial are always related to the axis of rotation of a multi-clutch device or hybrid module within the scope of the present invention.

The present invention relates to a multi-clutch device for a hybrid module for connecting an internal combustion engine. The multi-clutch device of the present invention includes a separable clutch that enables torque to be transmitted from an internal combustion engine to the multi-clutch device and separates the multi-clutch device from the internal combustion engine; and a further clutch device enabling transmission of torque from the electric machine and/or from the decoupled clutch to the power train. The additional clutch device may in particular be a double clutch device with a first partial clutch and a second partial clutch. In addition, the multi-clutch device of the present application includes a housing; and a common rotational member rotatably coupling the additional clutch and the separable clutch, wherein the multi-clutch device includes a fixed bearing and a floating bearing for rotational support of the common rotational member with respect to the housing. Including, the fixed bearing and the floating bearing are each supported by the housing and the common rotating member in the radial direction.

The radial support of the fixed and floating bearings on the housing and on the common rotating member is preferably carried out without intervening or directly on the components. In this case, the housing is in particular a static component of the multi-clutch device, on which the common rotational member can rotate relative to it. However, in this case, it is not excluded that the housing can also perform rotational movement within the power train as the case may be.

The fixed bearing is preferably a double row roller bearing and the floating bearing is a needle bearing.

The arrangement of the fixed bearings ensures absorption of the axial forces acting in the multi-clutch device, so that no axial forces are exerted on the further components of the multi-clutch device, or only slightly.

For the purpose of using a multi-clutch device in a double-clutch transmission, the additional clutch device is a double clutch device having a first partial clutch and a second partial clutch, and the multi-clutch device herein provides a first operation for operating the first partial clutch. and an actuation system with a second actuating device for actuating the device and the second partial clutch. Axial forces from the first actuating device and the second actuating device are transmitted to a common rotating member, from which the axial forces are transmitted back to the fixed bearing. And axial forces from the fixed bearings are introduced into the fixed housing.

The first actuating device and the second actuating device may at least partially overlap each other in the radial direction. In other words, a radially nested double central locking device or a double central release device can be applied here for the double clutch device. In this case, the two actuating devices can each comprise a substantially annular piston/cylinder unit having a piston which can be displaced substantially in translation in the axial direction, in addition, each comprising said piston/cylinder unit and each A portion of the clutch may also include an annular actuating bearing allowing relative rotational movement between the clutch members to be actuated, in which case the radial extension of each piston/cylinder unit in relation to the axis of rotation extends to the axis of rotation of the raceway of the respective actuating bearing. is exactly the same size as the separation distance of

In another embodiment of the present multi-clutch device, the two-part clutch each comprises an inner plate carrier, in particular with lining plates, and an outer plate carrier, in particular with steel disks, wherein the inner plate carrier and the outer plate carrier are torqued. For the purpose of transmission, the forces applied by the respective operating devices may reach a state of frictional engagement with each other, wherein each inner plate carrier may be or is connected to rotate integrally with the transmission input shaft, and each outer plate The carrier is connected for rotation integrally with the common rotational member or is formed by the common rotational member.

The split clutch can be overlapped radially by means of a double clutch device. In this case, the split clutch can be arranged radially inward with respect to the double clutch device, and the two part clutches of the double clutch device can be arranged substantially axially next to each other.

In one embodiment of the present multi-clutch device, the fixed bearing and the floating bearing are supported on a housing with their respective radially inner faces and supported on a common rotating member with their respective radially outer faces. This means that in the above embodiment of the present multi-clutch device, the common rotating member is arranged on the radially inner face of the housing in relation to the at least one section of the housing.

In particular, the common swivel member may have a protrusion extending substantially in the axial direction, the radially inner surface of the protrusion being used for support via a fixed bearing.

Further, the housing may include a substantially axially extending protrusion, the radially outer face of which is used for support via a fixed bearing. Thus, in this embodiment the fixed bearing is disposed between the two axially extending protrusions of the housing and the common rotary member. A floating bearing can be arranged next to the fixed bearing, so that it can likewise be supported by the axial projection of the housing.

In one embodiment, the fixed bearing is arranged radially inside the split clutch. In the preferred configuration of the additional clutch device as a double clutch device, the fixed bearing is located radially also inside the partial clutches of the double clutch device. In particular, an embodiment is provided in which the two-part clutch of the double clutch device radially overlaps the split clutch, and the split clutch radially overlaps the fixed bearing. In doing so, a multi-clutch device requiring a very small mounting space in the axial direction is provided. In this case, the floating bearing can be arranged axially outside the split clutch or outside the partial clutches of the double clutch device, the floating bearing having substantially the same rotational diameter as the fixed bearing and axially in relation to the fixed bearing. is offset in the direction of the internal combustion engine connection.

Preferably, the split clutch is assigned a split clutch actuation system by means of which a substantially axial force can be applied to the split clutch for the purpose of actuating the split clutch.

The separable clutch may include an inner plate carrier, in particular with lining plates, and an outer plate carrier, in particular with steel plates, which can be frictionally engaged with each other by means of a force applied by the separable clutch actuation system for the purpose of transmitting torque, The outer plate carrier is connected to rotate integrally with the clutch input shaft, and the inner plate carrier is coupled to rotate integrally with the common rotation member.

In an alternative embodiment, the outer plate carrier is integrally rotatably connected with the clutch input shaft and the inner plate carrier is integrally rotatably coupled with the common rotational member.

The split clutch actuation system is axially supported on or within the housing. The separable clutch also includes a back pressure member for counteracting an axial force applied by the separable clutch actuation system, the back pressure member forming an inner plate carrier of the separable clutch and being at least axially connected directly with the axially extending protrusion of the common rotational member. It is fixedly connected in a direction or at least axially fixedly connected directly with the shell carrier of the separable clutch. The back pressure member applies a force that counteracts the axial force caused by the split clutch actuation system, causing the plates of the split clutch to come into close contact with each other, thereby engaging the split clutch.

In this case, the back pressure member is supported on the common rotational member or the axial projection of the common rotational member, or supported on the shell carrier of the separable clutch, and this shell carrier is again fixedly connected with the common rotational member. Thus, in both embodiments, the reaction force to the axial force exerted by the split clutch actuation system is introduced into a common rotating member supported on the fixed bearing, so that the fixed bearing as a whole must withstand the axial loading.

The detachable clutch actuation system preferably comprises a substantially annular piston/cylinder unit having a substantially axially translationally displaceable piston; In addition, an annular actuating bearing allowing relative rotational motion between the piston/cylinder unit and a clutch member to be actuated of the detachable clutch. In this case, the piston/cylinder unit is accommodated in or in the housing.

In addition, the multi-clutch device of the present invention may include a transmission element for forming a transmission between the electric machine and the multi-clutch device for the purpose of transmitting rotational motion between the electric machine and the multi-clutch device. The shift member is a chain sprocket for forming a chain drive, a belt pulley for forming a belt drive, or a gear wheel for forming a gear drive. The realized gear drive can be single-stage or multi-stage.

In this case, the individual clutches and shift member of the multi-clutch device of the present invention may be arranged in one wet chamber.

In particular, the multi-clutch device of the present application is formed in such a way that a common rotating member has circumscribed teeth on an outer surface in the radial direction, and a gear wheel engaged with the circumscribed teeth to mesh with teeth on a rotor of an electric machine is provided. can In this way, torque can be transferred from the multi-clutch device to the electric machine via the gear drive for the purpose of regenerative braking and vice versa for the purpose of driving the electric motor.

The structure allows the use of wear-reducing wet clutches without the need to omit the combination with the operation of an electric motor for the formation of a hybrid module. The multi-clutch device of the present invention may be formed in such a way that the clutches and the gear member are coaxially arranged around a common rotational axis. In this case, the effective diameter of the gear member is larger than the effective diameter of the components of the detachable clutch that transmit torque by frictional engagement. In other words, by arranging the effective pitch circle of the gear member radially outward with respect to the split clutch, the radial separation distance of the effective pitch circle of the gear member through which torque transmission by the gear member is made to the rotational axis is increased. , greater than the radial separation distance to the axis of rotation of the plates of the separable clutch, which are used to transmit torque inside the separable clutch via frictional engagement. However, the radial distance of the effective pitch circle of the gear element, through which the transmission of torque by the gear element, to the axis of rotation is the radial distance of the plates of the partial clutches used to transmit the torque inside the respective clutch through frictional engagement. smaller than

In another preferred embodiment, the fixed bearing is formed as a single-low ball bearing, and the present multi-clutch device includes an additional fixed bearing disposed between the housing and the clutch input shaft. The clutch input shaft is used to rotatably connect the multi-clutch device to the internal combustion engine.

The additional fixed bearing is preferably a single row ball bearing as well. In this case, the clutch input shaft is fixedly engaged with the input side of the separable clutch in a rotational manner. In this way, an additional axial support of the separable clutch components on the housing is realized, and the first mentioned fixed bearing is correspondingly relieved in the axial direction.

In addition, in order to solve the problem of the ball invention, a hybrid module including a multi-clutch device according to the present invention and an electric machine for generating drive torque using a rotor is provided, in which case the rotor is a multi-clutch device and a rotary type In short, it is preferably connected by a gear device including a gear member of a multi-clutch device. Accordingly, torque or rotational motion is transferred from the electric machine to the multi-clutch device by means of the gearing, for driving the multi-clutch device and thus driving the drive module, or from the multi-clutch device in the opposite direction for the purpose of regenerative braking. It can be transferred to an electric machine.

In this case, the rotor of the electric machine may be disposed outside the wet chamber, and may be connected to rotate integrally with an additional gear member forming a gear unit together with the gear member of the multi-clutch device, or may be connected. A further gear element can likewise be arranged in the wet chamber, and a seal for sealing the wet chamber can be arranged between the further gear element and the rotor of the electric machine.

Complementary to this, a drive system for a vehicle having an internal combustion engine and a hybrid module according to the present invention as well as a vehicle transmission is provided, in which case the hybrid module is mechanically connected with the internal combustion engine and the vehicle transmission via clutches of the hybrid module.

The present invention described above is explained in detail in the following with reference to related drawings in which preferred embodiments are shown in a related technical background. It should be noted that the present invention is not limited in any way by the schematic drawings, and the embodiments shown in the drawings are not limited to the extent shown.

1 is a partial sectional view of a first embodiment of a multi-clutch device according to the present invention.
2 is a partial cross-sectional view of a second embodiment of a multi-clutch device according to the present invention.
3 is a partial cross-sectional view of a third embodiment of a multi-clutch device according to the present invention.

The embodiment according to FIG. 1 comprises a double-row fixed bearing 60 and a floating bearing 61 designed as a needle bearing.

Corresponding bearings are also provided in the embodiment shown in FIG. 2 . This embodiment includes a transmission member 70 mounted on a hollow shaft 140 by means of a needle bearing 150, which gear member is here formed as a gear wheel and has circumscribed teeth on a common rotary member 80 and are combined

Another difference of the embodiment shown here with respect to the embodiments shown in Figs. 1 and 3 is that in the embodiment shown in Fig. 2 the diameter of the working bearing 20 of the separating clutch 10 is in that it is substantially exactly the same size as the diameter of the piston/cylinder unit 12 of the system 11.

The embodiment shown in FIG. 3 includes a fixed bearing 60 only as a single row ball bearing.

The following description of the invention relates to all three embodiments shown in FIGS. 1-3.

On the common rotational axis 1 there are disposed not only a split clutch 10, but also an additional clutch device 30 designed as a double clutch device. The double clutch device 30 includes a first partial clutch 40 and a second partial clutch 50 . All three clutches 10, 40, 50 may be disposed within one wet chamber 90. This means that in the above embodiment of the multi-clutch device, all three clutches 10, 40 and 50 are formed as wet clutches. In addition, all three clutches 10, 40 and 50 are rotatably coupled to each other via one common rotating member 80.

To the split clutch 10 is assigned a split clutch actuation system 11 comprising an annular piston/cylinder unit 12 and a working bearing 20 . In this case, the radial extension 13 of the piston/cylinder unit 12 is greater than the radial separation of the raceway 21 of the working bearing 20 to the axis of rotation 1 .

It can be seen that the effective diameter of the shift member 70 is larger than the effective diameters of the components of the detachable clutch that transmit torque by frictional engagement. Based on the relatively large separation distance of the transmission member 70 from the rotating shaft 1, it is possible to construct an electric machine having a relatively small driving output or a torque resulting therefrom. In addition to this, the possibility of arranging the electric machine in an axis-parallel manner, spaced apart from the axis of rotation, enables the realization of a more flexible arrangement of hybrid modules with excellent mounting space efficiency or device assemblies of hybrid modules within the power train of a vehicle. let it

When one of the partial clutches 40 and 50 connected to the common rotation shaft 80 is engaged, the torque from the partial clutches 40 and 50 is applied to each of the first outer plate carriers 44 and the second outer plate carriers 54. It is transmitted to each of the first inner plate carrier 42 to the second inner plate carrier 52 and to the first transmission input shaft 100 to the second transmission input shaft 101 via the . For this purpose, either the first pressure port 46 by means of the first actuating device 41 or the second pressure port 56 by means of the second actuating device 51 is connected to the respective partial clutch 40 , 50 . is displaced in the axial direction for fastening.

A fixed bearing 60 is disposed between the housing 110 and the common rotating member 80, and an additional fixed bearing 62 is disposed between the clutch input shaft 130 and the housing 110.

Thus, the clutch input shaft 130 is supported via an additional fixed bearing 62 . In addition to the fixed bearing 60, a floating bearing 61 in the form of a needle bearing is arranged towards the connection of the internal combustion engine. This floating bearing 61 is used for absorption of radial forces. Thus, only a slight radial force is applied to the fixed bearing 60 as well as to the further fixed bearing 62, so that the fixed bearings can be designed substantially for the loading of axial forces, correspondingly Thus, wear in bearings can be reduced. It can be seen that the floating bearing 61 is not positioned radially inside the detachable clutch 10 . In this way, the floating bearing 61 can cancel the tilting moment in the split clutch or even in the additional clutch device 30 .

The fixed bearing 60 and the floating bearing 61 support, with their radially outer faces, a common rotational member 80 or a protrusion 81 extending in the axial direction of the common rotational member, which protrusion is the clutch input. It extends between the shaft 130 and the detachable clutch 10 . In this case, the fixed bearing 60 and the floating bearing 61 run on or within the housing 110, in short here substantially parallel to the axially extending protrusion 81 of the common rotating member 80. While extending in the axial direction, it is seated on the protrusion 111 of the housing 110.

The axial force exerted by the split clutch actuation system 11 is such that the lining plate 23 as well as the steel plate 26 are pressed together so that a torque can be transmitted through said plates 23, 26. (10) works. A further clutch device 30 formed as a double clutch device comprises a first partial clutch 40 and a second partial clutch 50, which include a first operating device 41 and a second operating device 51 is assigned The actuation devices 41, 51 likewise transmit an axial force through their pressure pots 46, 56, which axial force is applied by the split clutch actuation system 11. directed in the direction opposite to the directional force. Via the respective lining plates 43, 53 and the steel plates 45, 55 alternately arranged therewith, the axial force generated by the actuating devices 41, 51 is applied to the first shell carrier ( 44) and transferred to the second shell carrier 54. In this case, the two shell carriers 44 and 54 are arranged on or formed by a common rotational member 80 . The common rotating member 80 is again axially supported on a fixed bearing 60, which in turn is axially supported on the housing 110.

Torque can be transmitted from a drive shaft or clutch input shaft 130, which can be coupled with a combustion unit not shown here, into the split clutch 10 via the shell carrier 25 of the split clutch 10. When engaging the separable clutch 10 using the operation of the separable clutch actuation system 11, the torque from the separable clutch 10 is transmitted to the common rotating member 80, that is, the torque applied by the separable clutch actuation system 11 A reaction force to the force is transmitted by the back pressure member 14. These forces cause the plates 23 and 26 of the detachable clutch 10 to be pressed against each other.

In the embodiment shown in FIG. 1 , the back pressure member 14 is fixedly engaged with the common rotation member 80 in the axial direction, so that the axial force introduced into the back pressure member 14 is directly connected to the common rotation member 80. and is applied to the fixed bearing 60 from this common rotating member.

In the embodiment shown in Fig. 2, the back pressure member 14 is a component of the shell carrier 25 of the separable clutch 10, and this component is fixedly connected with the common rotational member 80 or said common rotational member. is formed by Correspondingly, here again the axial forces are transmitted via the common rotating member 80 to the stationary bearing 60 .

In the embodiment shown in FIG. 3 , the back pressure member 14 is in fixed connection with the clutch input shaft 130 in the axial direction, whereby the axial forces introduced into the back pressure member 14 are reduced by the additional fixed bearing 62 ) and is directly transmitted to the clutch input shaft 130 supported on the housing 110.

On the common rotary member 80, a shift member 70, which in the embodiment shown here is a chain sprocket for the formation of a chain drive, is fixedly arranged. The chain drive is coupled with a pinion of an electric machine (not shown here) disposed outside the wet chamber 90 . In this way, torque is transmitted from the electric machine to the common rotating member 80 and thus to all three clutches 10, 40, 50 in total and vice versa. A seal, not shown here, for sealing the wet chamber 90 is arranged between the pinion assigned to the electric machine and the rotor of the electric machine.

Although the first actuating device 41 assigned to the first partial clutch 40 and the second actuating device 51 assigned to the second partial clutch 50 are radially arranged in an interleaving manner with each other, , structures arranged side by side with each other in the axial direction are not excluded.

Therefore, based on the invention proposed here, the arrangement of the fixed bearing ensures the absorption of axial forces so that no or very little axial force is exerted on the further components of the multi-clutch device, A multi-clutch device and hybrid module combining reduced wear with reduced axial and radial mounting space is provided.
