Definitions

• the present invention relates to a hybrid module for a drive train of a motor vehicle, with a clutch (K0) for selectively engaging and disengaging an internal combustion engine from an electric motor driven intermediate shaft, with a coupling device which is prepared for selective torque transmission (torque transfer) to a transmission input shaft, and with a housing.
• Hybrid modules are well known in the art.
• DE 10 2009 059 944 A1 discloses a hybrid module for a drive train of a motor vehicle having a first disconnect clutch, an electric motor and a second disconnect clutch, the first disconnect clutch in the torque flow between an internal combustion engine in the drive train and the electric motor and the second disconnect clutch in the torque flow between Electric motor and a transmission are arranged in the drive train, wherein the first separating clutch and the second separating clutch are arranged in a common wet space.
• hybrid modules with a triple clutch or with three clutches are very complex and seen in particular in the axial direction space consuming / space-consuming.
• hybrid modules are already known in which the separating clutch is arranged outside the housing of the hybrid module or the transmission and are thus designed as a dry clutch.
• the actuating forces on a dry running clutch through the grease lubricated release bearing are severely limited.
• such release bearings require additional space.
• the object of the invention is therefore to avoid or at least mitigate the disadvantages of the prior art, and in particular to provide an arrangement of the triple clutch, which has a reduced space requirement, the complexity of the structure is reduced and high operating forces, in particular on the separation coupling, are possible.
• the object of the invention is achieved in a generic hybrid module according to the invention in that the separating clutch is arranged outside of the housing, while the coupling device is disposed within the housing.
• the separating clutch is designed as a dry clutch. This makes it possible to arrange them outside of the space limited by the housing of the hybrid module.
• the coupling device is designed as a wet clutch. With wet-running clutches, the bleeding of the clutches is easier, which means that there are less drag torques. Furthermore, the maximum possible actuating forces of the actuating unit or the disengaging device, for example in the form of a double CSC (a double Concentric Slave Cylinder) are higher than in a dry-running clutch unit. It has proven to be advantageous if the coupling device is designed as a double clutch with a first part clutch (K1) and a second part clutch (K2). For this purpose, it is particularly advantageous if the double clutch radially and axially within a rotor of an electric machine, such as.
• K1 first part clutch
• K2 second part clutch
• an electric motor is arranged, wherein the partial clutches in the radial direction preferably stacked, or nested, are arranged.
• the space in the axial direction can be further reduced, while the space in the radial direction remains at least equal (or is also reduced).
• the separating clutch has a bearing on the intermediate shaft and mitfitendes with this release system.
• a co-rotating release system is both axially and radially space-saving.
• the co-rotating release system comprises a rotary feedthrough.
• the co-rotating disengagement system has a drive housing arranged on the intermediate shaft.
• This arrangement has the great advantage that the transferable forces are not dependent on a release bearing and therefore can be designed very high, since the separating clutch is constructed so that the co-rotating release system, the clutch and the driver housing, an internal, self-contained Kraft Wegverlauf enable. This allows a dry single-disc clutch to be used and the motor-side driver to be mounted directly on the DMF side (on the side of the dual-mass flywheel). In order to seal the co-rotating release system from its environment, it is advantageous if the co-rotating release system is sealed with respect to the intermediate shaft and the driver housing each with a (rod) seal.
• a fluid line for control or actuation of the co-rotating disengaging system extends transversely through the intermediate shaft and the housing or runs longitudinally along the transmission input shaft. It is particularly advantageous if the fluid line radially from extends externally through the intermediate shaft and the housing and a rotary feedthrough, which allows the passage of the fluid from the line to the co-rotating disengagement system, between a housing portion and the intermediate shaft or the fluid line runs parallel within the transmission input shaft, wherein the rotary union outside the Transmission input shaft is provided.
• the invention consists in that the separating clutch KO and the clutches K1 and K2 are provided separately from each other.
• the K0 coupling should run outside the installation space of the hybrid module, preferably in a dry version. This is controlled by means of a rotary feedthrough.
• the clutches K1 and K2 run in the wet space, are mounted within the rotor and arranged radially nested. Furthermore, they are operated via a double CSC. This approach is extremely space-saving.
• a rotor position sensor can optionally, depending on the desired design, be arranged left or right of the rotor.
• the invention provides a hybrid module in which a dual clutch, which comprises a first and a second partial clutch, is provided within the hybrid module, more specifically radially and axially within a rotor of an electric machine of the hybrid module.
• a disconnect clutch is provided separately from the dual clutch outside of a housing of the hybrid module.
• the separating clutch is a dry clutch and the dual clutch is a wet clutch.

• the hybrid module 1 has a separating clutch (also called KO clutch) 2, which is used for selective engagement and disengagement of an internal combustion engine (not shown) of an electric motor driven intermediate shaft 3, and a Kupplungsvorrich- device 4, which for selectively transmitting torque to a Transmission input shaft 5 is prepared.
• a separating clutch also called KO clutch
• the hybrid module 1 comprises a housing 6, which spatially separates the separating clutch 2 and the coupling device 4 from each other and thus the building cavities in a dry area 7, which is left side of the housing 6 in Fig. 1, and a wet area. 8 , which is arranged in Fig. 1, the right side of the housing, divides.
• the coupling device 4, which is located in the wet area 8 has a first partial clutch (also called K1 clutch) 9 and a second partial clutch (also called K2 clutch) 10, which are arranged nested in the radial direction and therefore in axial direction require very little space.
• the separating clutch 2 is designed as a dry clutch, which has a co-rotating release system 1 1 and a driver housing 12. Both the co-rotating release system 1 1 and the driver housing 12 are arranged on the intermediate shaft 3 so that they rotate with the intermediate shaft 3. On the driver housing 12, a pressure plate 13 and a counter-pressure plate 14 are attached. Between the pressure plate 13 and the counter-pressure plate 14 clutch discs 15 are arranged, which are attached to an internal combustion engine side driver 16, which in turn is mounted directly on the side of a dual mass flywheel 17 (ZMS side). This is possible because the counter-pressure plate 14 is limited on the side facing the dual mass flywheel 17 radially outward by a support ring 36 in its axial movement.
• ZMS side dual mass flywheel 17
• the co-rotating release system 1 1 has a rotary feedthrough (not shown), which allows a fluid which is passed through a fluid line 18 is conveyed into a piston 19, which also rotates with the intermediate shaft 3 with, and to Displacement of the release system 1 1 is used, whereby the separating clutch 2 is actuated.
• the piston 19 is sealed off from the dry area 7 via seals 20, 21, which are preferably designed as rod seals, in order to prevent fluid leakage (leakage) within the dry area 7.
• the piston 19 applies an axial force to the clutch pack of the clutch 2.
• the transmission input shaft 5 is made in two parts in the embodiment shown here and hollow inside.
• the fluid line 18, which supplies the co-rotating release system 1 1 with fluid in this case runs parallel to the transmission input shaft 5 and is sealed by a sealing ring 23 with respect to the cavity 22 of the transmission input shaft 5.
• the intermediate shaft 3 is mounted on the transmission input shaft 5 via a bearing 24 in order to enable a relative rotation between the intermediate shaft 3 and the transmission input shaft 5.
• the intermediate shaft 3 and the transmission input shaft 5 overlap in the axial direction in the region of the bearing 24, wherein the intermediate shaft 3 is arranged radially outside of and around the transmission input shaft 5 circumferentially.
• the intermediate shaft 3 also has a cavity, which is provided with the reference numeral 35.
• the housing 6 is supported on the intermediate shaft 3 via a bearing device 25.
• an electric machine 26 is arranged in the form of an electric motor.

• the stator 27 is rotatably connected to the housing 6 and rotatably attached thereto (not shown here) and the rotor 28 is supported via a central bearing 30 on the housing 6.
• Radially inside the rotor 28, the coupling device 4 is arranged so that the first part clutch 9 and the second part clutch 10 are arranged radially nested one inside the other.
• the coupling device 4 is actuated via a double executed CSC (Concentric Slave Cylinder) 31, which may also be referred to as a double CSC 31.
