Description

Hybrid module and drive for a motor vehicle
Technical Field
The invention relates to a hybrid module for coupling an internal combustion engine and a transmission for a motor vehicle and to a drive for a motor vehicle.
Background
The mixing module generally comprises: a connecting device for mechanically coupling the internal combustion engine; a clutch device, by means of which torque can be transmitted from the internal combustion engine to the hybrid module and by means of which the hybrid module can be decoupled from the internal combustion engine; an electric machine having a rotor for generating a drive torque. The electric machine enables electric driving, power augmentation for the operation of the internal combustion engine and energy recovery. The clutch device and its actuation system ensure the coupling and decoupling of the internal combustion engine.
Hybrid modules of axially short design are known from the prior art.
For this purpose, DE 102014209833 a1 discloses a mixing module having: disengaging the clutch; an intermediate shaft drivable by the crankshaft; a clutch disk connected with the intermediate shaft in a torsion-proof manner; a counter plate which can be connected to the transmission input shaft and which is connected to the clutch disk in a rotationally fixed manner in at least one engagement position of the separator clutch; a first rolling bearing radially supporting at least the intermediate shaft; and a carrier element which is intended for radially supporting a rotor of the electric motor, wherein the first rolling bearing is arranged radially nested between the support section of the carrier element and an outer circumferential side of the intermediate shaft. The intermediate shaft is axially supported by a securing ring in a groove of the intermediate shaft, which securing ring is seated in a section of a damper, in particular a hub of a vibration damper, of the hybrid module.
When the hybrid module is integrated into a hybrid vehicle having an internal combustion engine, the axial movement of the crankshaft of the internal combustion engine is transmitted to the input shaft of the hybrid module. This causes a corresponding axial movement of the input shaft of the hybrid module and thus a high axially acting load in the hybrid module. In hybrid modules according to the prior art, the input shaft is usually supported axially rigidly. The axial loading of the input shaft causes correspondingly high loading of the bearing of the input shaft.
Disclosure of Invention
In view of this, it is an object of the present invention to provide a hybrid module and a drive device equipped therewith, which make it possible to realize an axial loading of an input shaft in the hybrid module in a structurally simple manner and in an effectively utilized installation space.
This object is achieved by a mixing module according to the invention according to claim 1. Advantageous embodiments of the mixing module are given in the dependent claims 2 to 8. In addition, a drive device for a motor vehicle having a hybrid module according to claim 10 is provided.
The features of the claims can be combined in any technically meaningful way and in any technically meaningful way, wherein the features set forth in the description below and in the drawings can also be added to this, which comprise additional embodiments of the invention.
The terms "axial" and "radial" always relate to the axis of rotation of the hybrid module within the scope of the invention.
The invention relates to a hybrid module for coupling an internal combustion engine and a transmission for a motor vehicle, comprising an input shaft and a support spring, wherein the input shaft is axially supported by means of the support spring. This means that the support spring serves to axially support the input shaft.
The hybrid module furthermore advantageously comprises a rotor support and an electric machine having a rotor, which is connected in a rotationally fixed manner to the rotor support, and a clutch device, for example a separating clutch.
The support spring can be axially supported on a component which is coupled in a rotationally fixed manner to the output side of the clutch device.
The component is an axially flexible plate component for coupling the output side of the clutch device to a shaft to be connected, for example a transmission input shaft.
An axially flexible plate element, also referred to as a flexplate, can itself be provided for connection to the transmission input shaft by means of a toothing, for example a splined internal toothing. In particular, the transmission input shaft includes splined shaft external teeth that are configured complementary to splined shaft internal teeth of the axially flexible plate member. The toothing can comprise an axial stop for axially bearing against the axially flexible plate member in order to absorb a counter force to the supporting force exerted by the supporting spring. If necessary, the support spring is supported in the radial region of the axially flexible plate element, which is likewise elastically effective, so that the support spring acts not only axially on the input shaft alone, but also the elastic restoring force of the axially flexible plate element.
In a constructively advantageous embodiment, the supporting spring is a disk spring. In particular, it is proposed here that the radially outer edge of the disk spring is supported on an axially flexible plate element and that the disk spring acts on the input shaft by means of its radially inner region.
According to a further embodiment, a plain bearing is arranged axially between the support spring and the input shaft for axially transmitting the support force exerted by the support spring to the input shaft.
The plain bearing can be designed as a disk, on the first side of which the input shaft is arranged and on the second side of which the support spring is arranged, wherein the disk can effect a slipping of the input shaft and/or the support spring at the respective bearing, so that a relative rotation between the input shaft and the support spring can be achieved. In this case, the disk can be produced as a plain bearing from a material such as teflon and/or have a surface or coating of a material such as teflon on its first and/or second side, whereby friction is minimized.
According to a further aspect, the hybrid module comprises a housing, wherein the input shaft is axially supported at the housing by means of a counter-support force which is directed counter to the support force of the support spring.
The housing is advantageously designed to be open on the side facing the transmission to be connected, so that the axially flexible plate element provided in the axial position can be used to axially support the input shaft via the support spring.
In particular, it can be provided that the support of the input shaft on the housing is realized by means of a plain bearing.
In a supplementary embodiment, the input shaft is radially supported on the housing by means of at least one needle bearing.
In particular, two needle bearings are provided for radially supporting the input shaft.
According to a further advantageous embodiment, the hybrid module further comprises a clutch actuation device, which is designed to actuate the clutch device, wherein the clutch actuation device is designed essentially as a piston-cylinder unit arranged coaxially with the rotational axis of the hybrid module.
Piston-cylinder units, also referred to as "concentric slave cylinders" (CSCs), generally comprise a cylinder serving as a pressure chamber and a piston which is translatably movable in the cylinder and whose movement serves to open and/or close a clutch device.
According to a further aspect, the support spring is connected substantially rotationally fixed to a component coupled to the clutch device.
This is achieved in particular in that, in the case of a support spring designed as a disk spring, the radially extending section of the disk spring or its outer edge projects through the wall of the component, in particular when the component is designed as an axially flexible plate component, in order to prevent rotation about the rotational axis of the hybrid module in such a form-fitting manner.
The hybrid module according to the invention has the advantage that the input load can be absorbed by the supporting springs, which allow a slight force-dependent movement of the input shaft. Correspondingly, the needle bearings provided for radial support of the input shaft are designed such that they allow small axial deflections so that no axial loads have to be absorbed.
Furthermore, according to the invention, a drive device for a motor vehicle is provided, which has a hybrid module according to the invention, a drive unit, in particular an internal combustion engine, and a transmission, wherein the hybrid module is connected on the input side to the drive unit and on the output side to the transmission.
The input side of the hybrid module is preferably realized here by an input shaft.

The invention is not limited in any way by the purely schematic figures, wherein it is to be noted that the embodiments shown in the figures are not limited to the specifications shown. Shown in the drawings are:
fig. 1 shows a cross-sectional view of a hybrid module according to the invention.
Detailed Description
The illustration of the hybrid module 1 shows a partial sectional side view of the hybrid module 1 integrated in the drive train. The hybrid module 1 includes an input shaft 10, a clutch device 50, a motor 40, an axially flexible plate member 60, and a damper 72. The hybrid module 1 further comprises a housing 2 in which the damper 72, the input shaft 10 and the motor 40 are arranged and in part the clutch device 50 is arranged.
The stator 41 of the electric motor 40 is connected in a rotationally fixed manner to the housing 2, wherein the rotor 42 of the electric motor 40 is arranged on a rotor carrier 43 so as to be rotatable about the rotational axis 5 of the hybrid module 1. For this purpose, the rotor carrier 43 is supported by means of a rotor carrier support section 44 in the radial direction via the support bearing 32 on the radially inner housing section 4 of the housing wall 3 of the housing 2 extending radially inward. The input shaft 10 of the hybrid module 1 is arranged radially inside the radially inner housing section 4 and is supported in the radial direction at the radially inner housing section 4 and thus at the housing 2 via two needle bearings 33 arranged on the radially outer side 11 of the input shaft 10. A damper 72 coupled to the input side 6 of the hybrid module 1 is arranged on the side of the housing wall 3 axially opposite the electric machine 40 and is connected in a rotationally fixed manner to the first axial end region 15 of the input shaft 10. Furthermore, the input shaft 10 comprises, on its side axially opposite the first axial end region 15 connected to the input shaft 10, a second axial end region 16 having a connecting section 12 for transmitting a torque to the clutch device 50.
A clutch device 50 is arranged radially between the input shaft 10 and the rotor 42 of the electric machine 40, wherein the clutch device 50 comprises two clutch discs 54, which are connected in a rotationally fixed manner to the connecting section 12 of the input shaft 10. The output 52 of the clutch device 50 is connected in a rotationally fixed manner to the rotor carrier 43 of the electric motor 40. The hybrid module 1 further comprises a clutch actuation device 53, which is designed as a piston-cylinder unit, wherein the clutch actuation device 53 is arranged on the side of the housing wall 3 of the housing 2 facing the electric motor 40 and engages through the rotor carrier support section 44 for actuating the clutch device 50.
An axially flexible plate member 60 is arranged axially beside the clutch device 50 and comprises a hub 61 and a resiliently acting radial area 62. The radial region 62 of the plate member 60 is connected in a rotationally fixed manner to the rotor carrier 43, wherein the hub 61 of the plate member 60, which is fixedly connected to the radial region 62, has an internal toothing 63, which is connected to an external toothing 71 of a transmission input shaft 70, which is partially shown here. Correspondingly, an axially flexible plate member 60 serves as the output side 7 of the hybrid module 1.
Furthermore, the hybrid module 1 comprises a support spring 20, a slide bearing 30 and a further slide bearing 31. The support spring 20 is designed here as a disk spring, wherein the support spring rests in the axial direction by means of the radially inner region 22 indirectly via the plain bearing 30 on the first contact region 13 of the connecting portion 12 of the input shaft 10 and by means of the radially outer region 21 on the elastically acting radial region 62 of the axially flexible plate element 60.
In this case, a plurality of projections 23 of the support spring 20 at its radially outer region 21, which projections are distributed over the circumference, project through openings (not visible here) in a radial region 62 of the plate member 60, in order to prevent a rotation about the axis of rotation 5 thereby while forming a form-fitting connection with the radial region 62. A further plain bearing 31 is arranged in the axial direction between the second contact region 14 of the connecting portion 12 of the input shaft 10 and the radially inner housing portion 4 of the housing wall 3 of the housing 2.
In a drive train of a hybrid vehicle, the hybrid module 1 is connected to an internal combustion engine as an input side 6 of the hybrid module 1 via a damper 72 and to a transmission unit as an output side 7 of the hybrid module 1 via an axially flexible plate element 60 via a transmission input shaft 70.
The torque provided by the internal combustion engine is correspondingly transmitted via the damper 72 to the input shaft 10 and thus via its connecting section 12 to the clutch device 50. In the clutch device 50 closed by the clutch actuation device 53, the torque is transmitted to the rotor carrier 43 and is further transmitted to the transmission unit via the axially flexible plate member 60. The torque provided by the electric machine 40 is transmitted directly via the rotor carrier 43 and via the plate member 60 to the transmission unit. The electric machine 40 and the internal combustion engine can thus provide torque in parallel for transmission to the transmission unit. In addition, in generator operation, torque can be transmitted from the internal combustion engine to the electric machine 40 for generating electrical energy. The electric machine 40 is also capable of delivering torque to the internal combustion engine for start-up assistance to the internal combustion engine.
Axial movements which are input into the hybrid module 1 and thus into the input shaft 10 by the internal combustion engine, in particular the crankshaft of the internal combustion engine, are absorbed by the supporting springs 20. The support spring 20 serves to axially support the input shaft 10. When the clutch device 50 is disconnected, relative rotation between the input shaft 10 and the plate member 60, and therefore between the input shaft 10 and the support spring 20, can occur. This relative rotation is facilitated here by the plain bearing 30. Furthermore, the spring force of the supporting spring 20 acts on the input shaft 10 axially in the direction of the internal combustion engine, wherein axial movement of the input shaft 10 in the direction of the internal combustion engine is correspondingly blocked by the contact of the input shaft 10 against a further plain bearing 31 on the radially inner housing section 4, wherein likewise the further plain bearing 31 allows relative rotation between the input shaft 10 and the housing 2.
With the hybrid module according to the invention and the drive according to the invention, axial loading of the input shaft in the hybrid module can be achieved in an efficient manner in terms of installation space and in a constructionally simple manner.
