Description

Mixed motion module
Technical Field
The present application relates to a hybrid module for coupling and decoupling an internal combustion engine to and from a powertrain of a motor vehicle. The hybrid module has an electric motor and a disconnect clutch which is arranged in the radial direction of the hybrid module in the electric motor and which has a counter plate, a pressure plate which is limitedly displaceable in the axial direction of the hybrid module, and an intermediate pressure plate which is arranged between the counter plate and the pressure plate and is limitedly displaceable in the axial direction. The separating clutch further has a clutch disk which can be clamped in a friction fit between the counter plate, the intermediate plate and the pressure plate.
Background
The drive train of a hybrid vehicle generally comprises a combination of an internal combustion engine and an electric motor, and enables a purely electric mode of operation, for example in densely populated areas, with both sufficient availability and sufficient useful travel during long-distance driving. Furthermore, there is the possibility of being driven by both the internal combustion engine and the electric motor under specific operating conditions. In hybrid vehicles, the electric motor generally replaces, on the one hand, the more early usual starter for the internal combustion engine and, on the other hand, the more early usual generator, in order to reduce the weight increase of the hybrid vehicle relative to a vehicle running only the internal combustion engine.
As is known from EP 0 773 A1, a disconnect clutch can be provided between the internal combustion engine and the electric motor in order to disconnect the internal combustion engine from the electric motor and the remaining drive train of the hybrid vehicle. In the pure electric mode, the off-clutch, also referred to as the K0 clutch, is then disengaged and the internal combustion engine is switched off, so that the drive torque of the hybrid vehicle is applied only by the electric motor.
Such disconnect clutches are typically operated by means of a hydraulic operating system. Hydraulic actuating systems generally have a master cylinder which transmits the pressure generated at the master cylinder to a slave cylinder via a hydraulic pressure line. The slave cylinder, with the clutch release bearing interposed, transmits hydraulic pressure to a lifting system by means of a piston displaceable in the axial direction, by means of which the friction fit at the release clutch is formed or released. All-hydraulic steering systems, as they are typically used in hybrid modules, can be equipped with, for example, a central separator, also commonly referred to as a Concentric Slave Cylinder (CSC). The central separator-based handling system requires a relatively large installation space within the mixing module.
The hybrid modules can be divided into the following categories P0 to P5 according to the arrangement or engagement points of the electric motor in the powertrain:
p0: the electric motor is arranged upstream of the internal combustion engine in the torque path and is coupled to the internal combustion engine, for example via a belt. In this arrangement of the electric motor, the electric motor is sometimes also referred to as a belt starter generator (RSG).
P1: the electric motor is disposed in the torque path immediately downstream of the internal combustion engine. The electric motor can be arranged, for example, in a torque path upstream of the starting or shifting clutch in a manner fixed to the crankshaft.
P2: the electric motor is disposed in the torque path between a disconnect clutch, commonly referred to as a K0 clutch, and a start or shift clutch, but is disposed in the torque path upstream of the vehicle transmission.
P3: the electric motor is disposed in the vehicle transmission and/or on the transmission output shaft.
P4: the motor is located at an existing or separate axle.
P5: the electric motor is arranged at or in the driven wheel, for example as a hub motor.
The disconnect clutch required for the hybrid drive of a conventional drive train must meet specific requirements with respect to design size and energy efficiency in comparison to conventional starting or shifting clutches. In particular, the disconnect clutch for the P2 hybrid module must be of particularly low drag torque in the disconnected or disconnected state. If the motor vehicle is driven by an electric motor and the internal combustion engine is switched off, a high rotational speed difference usually occurs in the disengaged clutch between the drive side and the driven side of the clutch over a longer period of time. Even small drag torques occurring in the disconnect clutch can rapidly cause an unacceptably large energy input due to large rotational speed differences. If the energy input in the disengaged clutch is too high, this may cause increased wear of the friction linings of the clutch discs and thus early failure of the disengaged clutch. The high energy input into the disengaged disconnect clutch can also negatively impact the effective travel that the motor vehicle can travel with battery charging without internal combustion engine support.
Disclosure of Invention
The object of the present application is to make it possible to realize a hybrid module having as compact a design as possible.
According to the present application, the object is achieved by a hybrid module having the features of the independent claims. Preferred embodiments of the mixing module are set forth in the dependent claims.
According to a first aspect, a hybrid module for coupling an internal combustion engine to and decoupling an internal combustion engine from a drive train of a motor vehicle is proposed, having an electric motor and a separating clutch which is arranged in the radial direction of the hybrid module within the electric motor and which has a counter plate, a pressure plate which is displaceably limited in the axial direction of the hybrid module and an intermediate pressure plate which is arranged between the counter plate and the pressure plate and is displaceably limited in the axial direction, and having a clutch disk which is clamped between the counter plate, the intermediate pressure plate and the pressure plate in a friction fit, wherein the electric motor has a rotor which is rotatably supported with respect to a stator of the electric motor by means of rotor webs, wherein the rotor webs are connected to a rotor carrier or transition into the rotor carrier outside the clutch disk in the radial direction, and the rotor is formed in a rotationally fixed manner with respect to the rotor carrier on the outer side of the rotor carrier. Since the pressure plate and/or the intermediate pressure plate is/are attached to the rotor carrier via the leaf springs on the inner side of the rotor carrier in a rotationally fixed manner or the rotor webs are or counter pressure plates, a compact design is possible.
According to a preferred embodiment, the rotor web is supported by the rotor bearing in a fixed position in the axial direction and rotatably at a support wall which indirectly or directly carries the stator of the electric motor. The required installation space is further reduced by the type of support.
It is furthermore advantageous if the rotor carrier and/or the rotor has recesses distributed in the circumferential direction of the mixing module, by means of which recesses the mixing module can be connected, in particular connected, in a rotationally fixed manner to the torque converter and/or the torque converter bridging clutch. By means of the recess, the required installation space can be reduced even further.
According to a further preferred embodiment, the pressure plate is in abutment with a pressure tank of a concentric hydraulic actuating device rotating with the rotor carrier for engaging and/or disengaging the separating clutch. Since a separate release bearing can thereby be dispensed with, the required installation space can be further reduced.
According to a further preferred embodiment, at least one of the clutch disks is connected in a rotationally fixed manner and in an axial direction to an input shaft which can be connected in a rotationally fixed manner to the internal combustion engine. As a result, the plug-in teeth that are movable in the axial direction do not have to be retained, whereby the required installation space can be further reduced.
Furthermore, it is advantageous if the input shaft is rotatably supported on the rotor web of the electric motor by means of axial and radial bearings. Thereby, the structural space required by the hybrid module is also further reduced.
Preferably, the input shaft has a flange, to which at least one of the clutch disks is attached in a rotationally fixed and elastic manner in the axial direction via at least one spring device, whereby the installation space required by the hybrid module can be further reduced.
It is furthermore advantageous if the first spring plate of the first spring device has perforations spaced apart in the circumferential direction of the mixing module, through which the axial section of the second spring device of the other clutch disk extends in the axial direction. The construction enables a particularly compact clutch disc assembly, whereby the structural space required by the hybrid module can be further reduced.
It is particularly advantageous if the friction linings of the further clutch disk are arranged on one side of the first spring plate in the axial direction and the second spring plate of the second spring device is arranged on the other side of the first spring plate in the axial direction for elastic attachment to the flange of the input shaft in the axial direction, as a result of which the installation space requirements of the clutch disk assembly or the hybrid module can be further reduced.
According to a second aspect, which can also preferably be considered independently of the first aspect and/or the preferred embodiments described above, a hybrid module for coupling an internal combustion engine to and decoupling it from a drive train of a motor vehicle is proposed, which has an electric motor and a separating clutch which is arranged in the radial direction of the hybrid module in the electric motor and which has a counter plate, a pressure plate which is limitedly displaceable in the axial direction of the hybrid module, and at least one clutch disk which is clamped between the counter plate and the pressure plate in a friction-fit manner, wherein the clutch disk is connected in an axially rotationally fixed manner in the rotor of the electric motor to an input shaft of the hybrid module. Since the input shaft is rotatably mounted with respect to the support wall of the electric motor, which indirectly or directly carries the stator, and is formed in the rotor in the axial direction without axial and radial bearings, the installation space of the hybrid module can be reduced.
Advantageously, the input shaft is rotatably supported by means of axial and radial bearings at the rotor webs of the electric motor, and the rotor webs are rotatably supported by means of the rotor bearings on the support wall. The installation space required by the mixing module can thereby be further reduced.
Preferably, the axial and radial bearings of the input shaft overlap the center of gravity of the input shaft in the axial direction. By this type of support no additional support bearing is required in order to prevent tilting of the input shaft, whereby the installation space required by the hybrid module can be further reduced.
Advantageously, the counter-pressure plate forms the rotor webs, as a result of which the installation space required by the mixing module can be further reduced.
According to a further preferred embodiment, the end of the input shaft on the combustion engine side has a guide bearing, by means of which the input shaft is rotatably supported on the crankshaft of the combustion engine. The mixing module itself can be constructed more compactly by this type of support.
According to a third aspect which can be considered preferably independently of the first and/or second aspect and/or the preferred embodiments above, a clutch disc assembly for a multi-disc disconnect clutch of a hybrid module for coupling and decoupling an internal combustion engine to and from a drive train of a motor vehicle is proposed, which has at least one first clutch disc and at least one second clutch disc, which are both rotationally fixed and fixedly fastened to a flange in the axial direction of the clutch disc assembly, and which each have spring means acting in the axial direction. Since the spring devices of the first clutch disk have perforations which are spaced apart in the circumferential direction of the clutch disk assembly, through which the axial sections of the spring devices of the second clutch disk extend in the axial direction, the clutch disk assembly can be embodied particularly compactly.
According to a preferred embodiment, the perforations are evenly spaced from each other in the circumferential direction by an angular dimension. Furthermore, the axial sections are uniformly spaced apart from one another in the circumferential direction by the same angular dimension, so that, when two clutch discs are assembled, they can be assembled rotationally relative to one another by an integer multiple of the angular dimension. Thereby, the structural space required by the clutch disc assembly can also be further reduced.
It is furthermore advantageous if the first clutch disk has a first imbalance and the second clutch disk has a second imbalance, and the two clutch disks are rotationally assembled relative to one another such that the total imbalance formed by the first imbalance and the second imbalance is minimized. A particularly compact clutch disk assembly can thereby also be achieved, in particular if no separate balancing weights are provided at the clutch disk assembly.
Preferably, the first clutch disk is attached to the flange in a rotationally fixed manner and in an axial direction by way of at least a first spring plate as the first spring means. Since the first spring plate has perforations which are spaced apart in the circumferential direction, the clutch disc assembly can be embodied particularly compactly.
It is furthermore advantageous if the second spring device has at least a spacer pin as an axial section, a lining carrier ring and a second spring plate, wherein the lining carrier ring is arranged on one side of the first spring plate and the second spring plate is arranged on the other side of the first spring plate, and the spacer pin connects the inner region of the lining carrier ring to the outer region of the second spring plate through a perforation in the first spring plate. Thus, a particularly compact clutch disc assembly is possible.
Preferably, the two spring plates are connected, preferably riveted, to the flange on different sides of the flange. The installation space requirement of the clutch disk assembly can thereby be further reduced.
Furthermore, a hybrid module for coupling and decoupling an internal combustion engine to and from a drive train of a motor vehicle is proposed, which has an electric motor and a separating clutch which is arranged in the radial direction of the hybrid module and which has a counter plate, a pressure plate which is limitedly displaceable in the axial direction of the hybrid module and an intermediate pressure plate which is arranged between the counter plate and the pressure plate and is limitedly displaceable in the axial direction, and a clutch disc assembly according to one of the embodiments described above, wherein a first clutch disc between the counter plate and the intermediate pressure plate and a second clutch disc between the intermediate pressure plate and the pressure plate are clampable in a friction fit. Such a hybrid module can be constructed particularly compactly.
Preferably, the electric motor has a rotor which is rotatably supported by a rotor tab with respect to a stator of the electric motor, wherein the counter plate forms the rotor tab. The installation space requirement of the hybrid module can thereby be further reduced.
It is also preferred that the flange is formed on the input shaft which is rotatably connected to the internal combustion engine, as a result of which the installation space of the mixing module is further reduced.
Furthermore, a method for mounting a clutch disc assembly of a multi-disc disconnect clutch of a hybrid module for coupling an internal combustion engine to and decoupling from a drive train of a motor vehicle, in particular according to one of the above-described embodiments, is proposed, which clutch disc assembly has at least one first clutch disc with a first imbalance and at least one second clutch disc with a second imbalance, wherein the two clutch discs are rotated relative to one another such that the total imbalance formed by the first imbalance and the second imbalance is minimized, and the two clutch discs are fixedly secured to a flange with the smallest total imbalance in torsion and in the axial direction of the clutch disc assembly. The method enables a particularly compact mounting of the clutch disc assembly.
According to a fourth aspect which can be considered preferably independently of the first and/or second and/or third aspect and/or the preferred embodiments above, a hybrid module for coupling an internal combustion engine to and decoupling from a drive train of a motor vehicle is proposed, which has an electric motor and a separating clutch which is arranged in the radial direction of the hybrid module within the electric motor and which has a counter plate, a pressure plate which is limitedly displaceable in the axial direction of the hybrid module and an intermediate pressure plate which is arranged between the counter plate and the pressure plate and is limitedly displaceable in the axial direction, and a clutch disk which is clamped between the counter plate, the intermediate pressure plate and the pressure plate in a friction fit, wherein the electric motor has a rotor which is rotatably supported by means of a rotor web in relation to a stator of the electric motor. Since the counter-pressure plate forms the rotor web, the mixing module can be constructed particularly compactly.
According to a preferred embodiment, the rotor web, which is formed as a counter plate, is connected to the rotor carrier outside the clutch disk in the radial direction or merges into the rotor carrier, on the outside of which the rotor is formed in a rotationally fixed manner with the rotor carrier. The installation space required by the mixing module can thereby be further reduced.
Advantageously, the pressure plate and/or the intermediate pressure plate are/is attached to the rotor carrier or the rotor web on the inner side of the rotor carrier in a rotationally fixed manner. The installation space required by the mixing module can thereby also be reduced further.
According to a fifth aspect which can be considered preferably independently of the first and/or second and/or third and/or fourth aspects and/or the preferred embodiments above, a hybrid module for coupling and decoupling an internal combustion engine to and from a drive train of a motor vehicle is proposed, which has an electric motor and a separating clutch which is arranged in the radial direction of the hybrid module in the electric motor and which has at least two pressure plates, at least one of which is rotationally fixed in a rotor carrier by means of a rivet connection by means of a leaf spring and can be moved in the axial direction of the hybrid module towards the other pressure plate in order to clamp a clutch disk between the pressure plates in a friction fit, on the outside of which the rotor of the electric motor is rotationally fixed to the rotor carrier. Since the rivet connection delimits the engagement path of one pressure plate before the wear limit of the clutch disk is reached, separate components for delimiting the engagement path can be omitted, as a result of which the hybrid module can be constructed particularly compactly.
Preferably, the wear limit of the clutch disc is reached if the friction lining of the clutch disc has the same height as the head of the rivet with which the friction lining is riveted with the spring means of the clutch disc.
According to a further preferred embodiment, the head of the riveted connection of the leaf spring can be brought into abutment with a further pressure plate or a component fixed with respect to the rotor carrier in order to delimit the engagement path of the one pressure plate. The installation space required by the mixing module can thereby be further reduced.
It is furthermore advantageous if one pressure plate is formed as a pressure plate and the other pressure plate is formed as a counter pressure plate of a single-disk or multi-disk clutch, which counter pressure plate is fixed in the axial direction.
Alternatively, it is advantageous if one pressure plate is formed as a pressure plate and the other pressure plate is formed as an intermediate pressure plate of the multi-disk clutch.
Furthermore, it is alternatively advantageous if one pressure plate is formed as an intermediate pressure plate and the other pressure plate is formed as a counter pressure plate of the multi-disk clutch, which is fixed in the axial direction.

Detailed Description
In fig. 1 to 7c, an embodiment of a hybrid module 1, more precisely of a P2 hybrid module, a clutch disc assembly 33 for a multi-disc disconnect clutch 7 of a hybrid module 1 and a method for mounting the clutch disc assembly 33 is shown. The features and feature combinations shown in the description of fig. 1 to 7c are not to be understood as optional as essential to the application.
The hybrid module 1 shown in fig. 1 in a half section has an input side 2 and an output side 3. The hybrid module 1 can be connected indirectly or directly to the internal combustion engine 4 via the input side 2. In the exemplary embodiment shown, the internal combustion engine 4 is connected to an input-side torsional vibration damper 5, which is, for example, a dual-mass flywheel with a curved spring or a straight compression spring, in particular in combination with a centrifugal pendulum. The torsional vibration damper 5 on the input side is connected in a rotationally fixed manner to the input side 2 of the hybrid module 1 via the output side of the hybrid module, preferably by means of a plug-in toothing 9.
On the output side 3 of the hybrid module, the hybrid module 1 is connected in a rotationally fixed manner to a torque converter and/or a torque converter bridging clutch 50. A transmission shaft 49 arranged coaxially with the input shaft 8 of the hybrid module 1 can extend through the torque converter and/or the torque converter jumper clutch 50. The input shaft 8 of the mixing module 1 extends in the axial direction a of the mixing module 1 and defines the rotation axis D of the mixing module 1.
The hybrid module 1 has an electric motor 6 and a disconnect clutch 7. The electric motor 6 is an electric motor which can be operated both as a drive and as a generator as a current generator. The disconnect clutch 7 is a so-called K0 clutch, which K0 clutch is designed to couple and decouple the internal combustion engine 4 to and from a drive train of the motor vehicle, in which the hybrid module 1 is arranged. The disconnect clutch 7 is arranged in the radial direction R of the hybrid module 1 within the electric motor 6. In the illustrated embodiment, the disconnect clutch 7 is configured as a dry multi-plate clutch, but can also be configured as a dry plate clutch or a dry single-plate clutch. As a design of the wet plate clutch, it is also possible.
On the input side 2 of the hybrid module 1, the torque of the internal combustion engine 4 can be transmitted either directly or indirectly via the torsional vibration damper 5 on the input side to the input shaft 8 of the hybrid module 1. The input shaft 8 can also be referred to as a countershaft or a hybrid shaft.
The input shaft 8 can also be the crankshaft itself of the internal combustion engine 4 or an extension of the crankshaft when the internal combustion engine 4 is directly attached to the hybrid module 1. The input shaft 8 is rotatably supported with respect to the motor 6 by bearings on the input side, which are designed as axial and radial bearings 11. For this purpose, an axial and radial bearing 11 is arranged between the inner input shaft 8 in the radial direction R and the outer rotor web 20 of the electric motor 6 in the radial direction R.
The input shaft 8 has an end 13 on the internal combustion engine side and an end 14 on the transmission side. The transmission-side end 14 defines the end of the input shaft 8 facing away from the internal combustion engine 4. In the exemplary embodiment shown, the end 14 of the input shaft 8 on the transmission side has a transmission shaft bearing 19, via which the input shaft 8 is supported and centered on the transmission shaft 49, when the plug-in toothing 9 is formed on the end 13 of the input shaft 8 on the internal combustion engine side. In the embodiment shown in fig. 1, the axial and radial bearings 11 on the one hand and the flange 10 of the input shaft 8 on the other hand are arranged in the axial direction a between the end 13 on the engine side and the end 14 on the transmission side.
The flange 10 of the input shaft 8 is formed inside the disconnect clutch 7 in the axial direction a. Likewise, the flange 10 of the input shaft 8 is formed in the radial direction R in the separating clutch 7. Furthermore, in the embodiment shown in fig. 1, the flange 10 is arranged in the axial direction a between the axial and radial bearings 11 and the transmission shaft bearing 19.
The flange 10 is part of a clutch disc assembly 33, which in the embodiment shown in fig. 1 has a first clutch disc 34 and a second clutch disc 35. At least one of the clutch disks 34, 35 is therefore fixedly connected in a rotationally fixed manner and in the axial direction a to the input shaft 8 which is rotatably connected to the internal combustion engine 4.
The separating clutch 7 has a counter-pressure plate 24 which is positionally fixed in the axial direction a, a pressure plate 27 which is limitedly displaceable in the axial direction a, and an intermediate pressure plate 26 which is arranged between the counter-pressure plate 24 and the pressure plate 27 and which is limitedly displaceable in the axial direction a. Furthermore, the separating clutch 7 has a clutch disk assembly 33 which can be clamped in a friction fit between the counter plate 24, the intermediate pressure plate 26 and the pressure plate 27, wherein the first clutch disk 34 can be clamped in a friction fit between the counter plate 24 and the intermediate pressure plate 26 and the second clutch disk 35 can be clamped in a friction fit between the intermediate pressure plate 26 and the pressure plate 27.
The electric motor 6 has a rotor 16 which is rotatably supported by a rotor web 20 with respect to the stator 15 of the electric motor. The rotor web 20 is connected to the rotor carrier 21 outside the clutch disks 34, 35 in the radial direction R or outside the clutch disk assembly 33 in the radial direction R or merges into the rotor carrier 21. On the outside of the cylindrical or pot-wall-shaped rotor support 21, the rotor 16 is formed in a rotationally fixed manner with the rotor support 21. The pressure plate 27 and/or the intermediate pressure plate 26 are attached to the rotor carrier 21 or the rotor web 20 or the counter pressure plate 24 via leaf springs 30 on the inner side of the rotor carrier 21 in a rotationally fixed manner.
In particular, the leaf springs 30 with the pressing plates 27 fastened thereto and the leaf springs 30 with the intermediate pressing plates 26 fastened thereto are disposed so as to be distributed in the circumferential direction U of the hybrid module 1. Where desired, the leaf springs 30 are spaced apart from the counter-pressure plate 24 in the axial direction a by intermediate elements 25, for example intermediate rings. In order to fasten the leaf spring 30 to the counter plate 24, a rivet connection 31 is preferably formed, which extends in the axial direction a through the counter plate 24, the intermediate element 25 and the leaf spring 30, more precisely through the end of the leaf spring 30 that is fixed in position in the axial direction a. The rivet connection 31 connects all three components or component groups, namely the counter plate 24, the intermediate element 25 and the leaf spring 30 to one another.
The rotor carrier 21 is arranged in the radial direction R outside the counter plate 24 or outside the intermediate element 25. The rotor carrier 21 is connected at its end facing the output side 2 of the mixing module 1 in a rotationally fixed and axially fixed manner to the counter-pressure plate 24 and/or the intermediate element 25. It is also possible here for the rotor carrier 21 to be formed in one piece with the counter plate 24 or with the intermediate element 25, wherein in the latter case the rotationally fixed and axially fixed attachment to the counter plate 24 is achieved by means of a riveted connection 31.
At its end facing the output side 3 of the hybrid module 1, the rotor carrier 21 has a rotor carrier flange 22 extending outwards in the radial direction R. The rotor carrier flange 22 is arranged in the axial direction between the rotor 16 on one side and the torque converter and/or torque converter crossover clutch 50 on the other side. The rotor carrier flange 22 has recesses 23 distributed in the circumferential direction U, which correspond to corresponding recesses extending in the rotor 16 in the axial direction a and corresponding recesses introduced into the housing of the torque converter or converter bridging clutch 50, in order to enable a rotationally fixed attachment of the hybrid module 1 to the torque converter or converter bridging clutch 50. For this purpose, screws are screwed, for example, by means of screws, which extend from the input side 2 through the rotor 16 and the rotor support flange 22 into the housing of the torque converter or the torque converter bridging clutch 50.
The rotor web 20 is connected in a rotationally fixed manner to the counter-pressure plate 24 in the region of the input-side end of the rotor carrier 21. Furthermore, the rotor web 20 is mounted in a fixed and rotatable manner in the axial direction a by means of the rotor bearing 18 on a support wall 17 which indirectly or directly carries the stator 15 of the electric motor 6. For this purpose, the rotor web 20 has a flange section in the region of the bearing, on the inner side of which the axial and radial bearings 11 are arranged, and on the outer side of which the rotor bearing 18 is arranged. The stator 15 is connected either directly to the support wall 17 or to a housing component which in turn is connected to the support wall 17.
The pressure plate 27 is in contact with a pressure tank 28 of a concentric hydraulic actuating device 29 which rotates together with the rotor carrier 21 for engaging and/or disengaging the separating clutch 7. The operating device 29 can be supported on a torque converter or a torque converter bridging clutch 50. Alternatively or additionally, the actuating device 29 can be supported on a transmission shaft 49. In any case, it is advantageous to supply the oil of the actuating device 29 via the transmission shaft 49.
The input-side clutch disc assembly 33 has at least a first clutch disc 34 and a second clutch disc 35. The two clutch disks 34, 35 are fastened to the flange 10 in a rotationally fixed manner and in the axial direction a of the clutch disk assembly 33 or the hybrid module 1. The first clutch disk 34 can be clamped in a friction fit between the counter plate 24 and the intermediate pressure plate 26. The second clutch disk 35 can be clamped in a friction fit between the intermediate pressure plate 26 and the pressure plate 27.
The two clutch discs 34, 35 each have a spring device 36, 37 which acts in the axial direction a. The spring means 36 of the first clutch disk 34 has perforations 40 spaced apart in the circumferential direction U of the clutch disk assembly 33 or the hybrid module 1. The axial section of the spring means 37 of the second clutch disc 35 extends in the axial direction a through the perforation 40.
More precisely, the first clutch disk 34 is attached to the flange 10 in a rotationally fixed manner and elastically in the axial direction a via at least one first spring plate 38 as a first spring device 36. Friction linings 43 are attached to both sides of the first spring plate 38 in a rotationally fixed manner in order to be able to bear against the friction surfaces of the counter-pressure plate 24 and the intermediate pressure plate 26 in a friction fit. The first spring plate 38 has perforations 40 spaced apart in the circumferential direction U.
The second spring device 37 has at least a spacer pin 42 as an axial section, a lining support ring 41 and a second spring plate 39. The lining carrier ring 41 is arranged on one side of the first spring plate 38, while the second spring plate 39 is arranged on the other side of the first spring plate 38. The spacer pins 42 connect the inner region of the lining carrier ring 41 with the outer region of the second spring plate 39 through the perforations 40 in the first spring plate 38. In the outer region of the lining support ring 41, friction linings 43 are mounted on both sides of the lining support ring 41 in a rotationally fixed manner, in order to be able to rest in a friction fit on the friction surfaces of the intermediate pressure plate 26 and the pressure plate 27. In summary, the friction linings 43 of the second clutch disk 35 are thus arranged on one side of the first spring plate 38, while the second spring plate 39 of the second spring device 37 is arranged on the other side of the first spring plate 38 for elastic attachment to the flange 10 of the input shaft 8 in the axial direction a.
The two spring plates 38, 39 are connected to the flange 10 on different sides of the flange in the axial direction a. Preferably, the connection is performed by riveting. It should be noted at this point that the separating clutch 7 can also be configured as a single-disk clutch, so that at least one of the clutch disks 34 or at least one spring device 36, 37 is attached to the flange 10 of the input shaft 8 in a rotationally fixed manner and in the axial direction a.
The embodiment of the hybrid module 1 shown in fig. 2 differs from the embodiment of the hybrid module 1 shown in fig. 1 in that the input shaft 8 is formed overall shorter. Thus, the flange 10 of the input shaft 8 forms a transmission-side end 14 of the input shaft 8. The input shaft 8 is rotatably mounted with respect to a support wall 17 of the electric motor 6, which carries the stator 15 indirectly or directly, and is formed in the rotor 16 in the axial direction a without axial and radial bearings. That is, unlike the embodiment of the hybrid module 1 shown in fig. 1, the transmission-side end 14 of the input shaft 8 does not extend into the transmission shaft 49 and does not have the transmission shaft bearing 19.
In the embodiment of the hybrid module 1 shown in fig. 2, the input shaft 8 is rotatably supported on the rotor web 20 of the electric motor 6 only by means of the axial and radial bearings 11. The rotor web 20 is rotatably supported on the support wall 17 by means of a rotor bearing 18. The axial and radial bearings 11 of the input shaft 8 overlap the center of gravity of the input shaft 8 in the axial direction a.
It should be noted that although the separating clutch 7 of the hybrid module 1 shown in fig. 2 is configured as a double-disk or multi-disk clutch, the separating clutch 7 can also be configured as a single-disk clutch having a counter-pressure plate 24 that is positionally fixed in the axial direction a and a pressure plate 27 that is limitedly displaceable in the axial direction a, and a single clutch disk that is arranged between the counter-pressure plate 24 and the pressure plate 27 in the axial direction a.
The embodiment of the hybrid module 1 shown in fig. 3 can also be constructed. The embodiment of the hybrid module 1 shown in fig. 3 differs from the embodiment of the hybrid module 1 shown in fig. 2 in that the input shaft 8 extends towards the input side 2 of the hybrid module 1, i.e. towards the internal combustion engine 4, and has a guide bearing 12 at its end 13 on the internal combustion engine side, preferably on the outer circumference of the input shaft 8. By means of the guide bearing 12, the input shaft 8 can be rotatably supported, for example, on an input flange of the input-side torsional vibration damper 5 or on another component connected to the crankshaft of the internal combustion engine 4 in a rotationally fixed manner. In particular, the input shaft 8 can be rotatably supported by means of a guide bearing 12 on the crankshaft of the internal combustion engine 4. It follows that the axial and radial bearings 11 of the input shaft 8 no longer overlap the center of gravity of the input shaft 8 in the axial direction a.
In the embodiment shown in fig. 4, the counter plate 24 of the disconnect clutch 7 forms a rotor web 20, by means of which the rotor 16 of the electric motor 6 is rotatably supported with respect to the stator 15 of the electric motor 6. More precisely, the counter plate 24 forming the rotor tab 20 is rotatably supported on the support wall 17 by means of the rotor bearing 18. The rotor webs, which are embodied as counter plates 24, are connected to the rotor carrier 21 in the radial direction R outside the clutch disks 34, 35, or, as shown in fig. 4, pass into the rotor carrier 21, i.e., are preferably embodied as one piece with the rotor carrier 21. On the outside of the rotor carrier 21, the rotor 16 of the electric motor 6 is formed rotationally fixed to the rotor carrier 21. The pressure plate 27 and/or the intermediate pressure plate 26 are attached to the rotor carrier 21 or to the rotor web 20 via leaf springs 30 on the inner side of the rotor carrier 21 in a rotationally fixed manner.
The separating clutch 7 of the hybrid module 1 shown in fig. 4 can be designed as a single-disc clutch or as a double-disc clutch or as a multiple-disc clutch, although only a single clutch disc 34 is shown in fig. 4. The same applies to the embodiment of the disconnect clutch 7 of the hybrid module 1 shown in fig. 5 and 6.
The separating clutch 7 of the hybrid module 1 shown in fig. 5 and 6 has at least two pressure plates 24, 26, 27, at least one pressure plate 26, 27 of which is rotationally fixed in the rotor carrier 21 by means of a leaf spring 30 by means of a rivet connection 31 and can be moved in the axial direction a of the hybrid module 1 toward the other pressure plate 24, 26 in order to clamp the clutch disk 34, 35 between the pressure plates 24, 26, 27 in a friction fit. The rivet connection 31 delimits the engagement path of the pressure plates 26, 27 before the wear limit of the clutch discs 34, 35 is reached. The wear limit of the clutch discs 34, 35 is reached when the friction linings 43 of the clutch discs 34, 35 have the same height H as the heads 45 of the rivets 44 with which the friction linings 43 are riveted with the spring means 36, 37 of the clutch discs 34, 35. In particular, the head 32 of the rivet connection 31 of the leaf spring 30 can be brought into contact with the other pressure plate 24, 26 or with a component fixed with respect to the rotor carrier 21 in order to delimit the engagement path of the one pressure plate 26, 27.
One pressure plate 26, 27 can be designed as a pressure plate 27, and the other pressure plate 24, 26 can be designed as a counter pressure plate 24 of the single-disk or multi-disk clutch 7, which is fixed in the axial direction a. Alternatively, one pressure plate 26, 27 can be designed as a pressure plate 27, and the other pressure plate 24, 26 can be designed as an intermediate pressure plate 26 of the multi-disk clutch 7. Alternatively, one pressure plate 26, 27 can be formed as an intermediate pressure plate 26, and the other pressure plate 24, 26 can be formed as a counter pressure plate 24 of the multiplate disconnect clutch 7, which is fixed in the axial direction a.
Fig. 7a to 7c show a method for mounting a clutch disk assembly 33 for a multi-disk disconnect clutch 7 of a hybrid module 1. The first clutch plate 34 has a first imbalance 46. The second clutch disc 35 has a second imbalance 47. The two clutch plates 34, 35 are rotated relative to each other such that the total imbalance 48 formed by the first and second imbalances 46, 47 is minimized. The two clutch disks 34, 35 are fastened to the flange 10 in a rotationally fixed manner with minimal overall imbalance 48 and in the axial direction a of the clutch disk assembly 33 or the hybrid module 1.
It is particularly advantageous here if the bores 40 provided in the spring arrangements 36 of the first clutch disk 34 are uniformly spaced apart from one another in the circumferential direction U by an angular dimension, and the axial sections of the spring arrangements 37 of the second clutch disk 35 are uniformly spaced apart from one another in the circumferential direction U by the same angular dimension, so that the two clutch disks 34, 35 can be assembled in a rotationally fixed manner relative to one another by an integer multiple of the angular dimension when they are assembled. The first clutch disc 34 with its first imbalance 46 and the second clutch disc 35 with its second imbalance 47 are then rotationally assembled with respect to each other such that the total imbalance 48 formed by the first and second imbalance 46, 47 is minimized, as shown in fig. 7 c.
