Description

Clutch device, hybrid module and drive device for a motor vehicle
Technical Field
The present invention relates to a clutch device for arrangement in a drive train of a motor vehicle, a hybrid module for a motor vehicle and a drive for a motor vehicle.
Background
From the prior art, various clutch devices are known for arrangement in a drive train of a motor vehicle.
Furthermore, hybrid modules provided in a drive device for a motor vehicle are known, which have a clutch device.
In this case, it can be provided that the clutch device is arranged in the torque transmission path between the internal combustion engine of the drive and the electric rotating machine of the hybrid module. Such a drive arrangement therefore has a so-called P2 setting so that completely different driving modes can be realized.
The clutch device is usually a releasable clutch for transmitting torque in a friction-fit manner between the input side and the output side of the clutch device. In the case of clutch devices of this type which are arranged as a friction-engaging separating clutch in the torque transmission path between the internal combustion engine and the transmission as the output device, for example, the torque transmission path can therefore be separated by opening the clutch device, whereby, for example, a change of the gear position, i.e. a gear change, can be carried out in the transmission.
In one known embodiment of the clutch device, the clutch device is designed to operate in dry mode and comprises a pressure plate and a counter-pressure plate and a clutch disk arranged between the plates, on which a friction lining is arranged. If, for example, a torque is transmitted to the clutch disk as the input side of the clutch device in order to set the clutch disk into a rotary motion, the pressure plate can be displaced by means of the actuating force in the direction of the clutch disk, so that the clutch disk is clamped in a friction-fitting manner between the pressure plate and the counter-pressure plate and the friction-fitting brings about the pressure plate and the counter-pressure plate in the rotary motion of the clutch disk. The clutch device is thus closed.
The actuating force can be provided by a rotationally fixed piston-cylinder unit of the actuating device, wherein an actuating bearing is provided in the actuating force transmission path between the piston-cylinder unit and the pressure plate, said actuating bearing allowing a relative rotation between the pressure plate and the piston-cylinder unit. In this embodiment, the actuating force that can be transmitted by the piston-cylinder unit to the pressure plate is limited, however, by the size of the piston-cylinder unit and the pressure prevailing therein.
In an alternative embodiment of the clutch device, the clutch device is designed to be wet, which means that the friction lining is in a wet environment. The wet design, however, results in a lower coefficient of friction at the friction surfaces of the elements of the clutch which rub against one another, so that a greater pressing force and/or pressing surface is required. Wet clutch devices are therefore usually provided with a plurality of clutch disks and an additional intermediate plate, which in turn increases the installation space requirement of the clutch device.
SUMMERY OF THE UTILITY MODEL
Starting from this, the invention is based on the object of providing a clutch device, a hybrid module equipped therewith and a drive assembly which ensure effective and reliable use in a structurally simpler and more space-saving manner.
The object is achieved according to the clutch device of the invention. Supplementarily, a hybrid module for a motor vehicle according to the invention is provided, the hybrid module having a clutch device according to the invention.
Furthermore, a drive device is provided with a clutch device according to the invention and/or a hybrid module according to the invention.
The features of the claims can be combined in any technically meaningful way and in any case, wherein the features set forth in the description below and in the drawings are also considered, which includes the additional embodiments of the invention.
The terms "axial" and "radial" always relate to the axis of rotation of the clutch device in the context of the present invention.
The utility model relates to a clutch device for setting in the power assembly of motor vehicle. The clutch device comprises a clutch disk coupled to the drive side and a pressure device coupled to the driven side, which has an axially displaceable pressure plate for pressing the pressure plate against the clutch disk in order to move the pressure plate in a frictional manner in the rotational movement of the clutch disk. The pressing device also has a pressure pot for applying a force to the pressure plate for the axial displacement thereof. The pressure tank is mounted in a housing of the clutch device so as to be axially displaceable and the housing partially delimits a pressure space for receiving a pressure fluid. According to the utility model discloses, the overhead tank can be driven in its rotational motion by clamp plate and/or casing.
This can be achieved in a simple embodiment such that the bearing pressure pot is carried out in a friction fit in the rotary motion. In particular, the driving is effected by a friction-fit connection, preferably a friction-fit connection with the housing. This means that no relative rotational movement takes place between the pressure tank and the pressure plate and between the pressure tank and the housing, so that a high tightness of the pressure space is ensured and the clutch device can be designed correspondingly as a dry clutch device.
Correspondingly, the pressure pot and thus also the pressure space can be designed such that a large surface is available, whereby a large force for moving the pressure pot and thus the pressure plate and a correspondingly large contact pressure force of the pressure plate on the clutch disk result at a defined fluid pressure in the pressure space, so that a correspondingly large torque can be transmitted by the clutch device.
The pressure pot and the pressure plate jointly form an actuator which can be rotated together. The pressing device comprises a pressure plate and a pressure tank, wherein the pressure tank acts on the pressure plate by means of pressure when delivering fluid into the pressure space and is used for moving the pressure plate.
The pressure tank thus constitutes a piston of a piston-cylinder system, which is movable when delivering fluid into a pressure space, also referred to as a cylinder space.
With the aid of the clutch device according to the invention, a torque can thus be transmitted from the drive side to the driven side in the rotary movement of the clutch disk as a result of the friction force driving the pressure plate. However, a torque transmission in the opposite direction is not excluded, for example in order to start an internal combustion engine connected thereto via the drive side of the clutch device by means of an electric rotating machine coupled to the driven side.
In one embodiment of the invention, the clutch device is a dry clutch device, wherein the pressure space is substantially liquid-tight.
In an embodiment of the pressure tank and of the embodiment of the housing of the clutch device delimiting the pressure space, it is proposed that the pressure tank is arranged displaceably in a liquid-tight manner on the housing. The liquid-tight displaceability is realized in particular in such a way that a seal, preferably in the form of a sealing ring, is provided between the pressure tank and the housing. For this purpose, for example, at least one sealing ring is provided in each case on the radially inner side or radially outer side of the pressure space. The respective sealing ring can be connected in a form-fitting manner to the housing or the pressure tank, so that a relative movement between the respective sealing ring and one of the elements, i.e. the housing or the pressure tank, is likewise achieved when the pressure tank is moved relative to the housing. In particular, it is preferred that the respective sealing ring is arranged in a radial recess in the housing.
According to a further aspect of the invention, the pressure plate and the pressure pot are two separate components which rest against one another for force transmission. In this way, the pressure pot and the pressure plate are set up for the axial transmission of force from the pressure pot to the pressure plate for its displacement. In an alternative embodiment, it is provided that the pressure plate and the pressure pot are integral components of a common component, which thus forms the pressure pot as a subregion close to the common axis of rotation and forms the pressure plate with respect to this remote from the axis of rotation.
According to a further embodiment, a counter plate is arranged on the side of the clutch disk axially opposite the pressure plate in a rotationally fixed manner with respect to the housing.
The counter plate serves to support the clutch disk when pressure is applied by the pressure plate and thus to achieve a static equilibrium in the axial direction when the clutch device is closed. This also results in a closed system with regard to the force flow, since the fluid pressure in the pressure space also acts on the side of the housing opposite this axial direction, so that the entire housing and thus the output side of the clutch device are in static equilibrium in the axial direction in the open state and also in the closed state. On the side of the counter-pressure plate axially opposite the clutch disk, a retaining ring can be provided which is connected to the housing and which fixes the axial position of the counter-pressure plate and via which the pressing force acting axially on the counter-pressure plate is thus supported at the housing.
In a further advantageous embodiment, the clutch device has a damper, wherein the pressure pot is arranged in the axial direction between the damper and a wall of the housing of the clutch device, which wall is arranged on the side of the pressure plate facing axially away from the clutch disk.
The clutch disk is coupled in a rotationally fixed manner to the damper via the friction lining carrier via an intermediate hub, wherein the output element of the damper is connected to the toothing of the intermediate hub.
The clutch disk therefore comprises, in addition to the friction linings, also referred to as friction linings, a friction lining carrier for positioning the friction linings at a defined distance from the axis of rotation of the clutch device and for introducing a torque from the intermediate hub into the friction linings. In particular, the toothing of the intermediate hub forms a driving toothing having an external toothing into which an internal toothing of the output element of the vibration damper engages in a rotationally fixed manner.
It can be provided that the intermediate hub is supported, preferably axially and radially, via a rotary bearing at the housing of the clutch device.
According to a further embodiment, the clutch device has at least one, in particular a plurality of springs, such as, for example, leaf springs, which are mechanically connected to the pressure plate and to the housing for transmitting a torque from the pressure plate to the housing and/or for resetting the pressure plate which is moved in the direction of the clutch disk.
Correspondingly, the leaf spring can be used to input torque from the clutch disk into the housing in addition to the existing counter plate. Furthermore, it also causes a return movement of the pressure plate pressed against the clutch disk in order to open the clutch device.
The pressure tank can also be reset in the pressure space by means of the pressure plate being reset by the leaf spring. The pressure tank is thereby displaced axially in the direction of the housing.
In an embodiment with an advantageous embodiment, at least one first flow channel is formed in the housing, which first flow channel is fluidically connected to the pressure space for feeding pressure fluid into the pressure space and/or discharging pressure fluid from the pressure space.
In this embodiment, it can furthermore be provided that the clutch device has an intermediate shaft which is coupled in a rotationally fixed manner to the housing, wherein a second flow duct is formed in the intermediate shaft, which second flow duct is fluidically connected to the first flow duct for supplying and/or discharging pressure fluid into and/or from the pressure space. The rotationally fixed coupling between the housing and the intermediate shaft can be realized by means of a toothing system, wherein the housing forms an inner toothing system on the radial inside, which engages with an outer toothing system on the radial outside of the intermediate shaft. In particular, the teeth are inserted in such a way that the housing can be inserted in the axial direction onto the intermediate shaft when the clutch device is installed or the intermediate shaft can be inserted in the axial direction into the housing for forming a rotationally fixed connection.
The second flow duct can be fluidically coupled to an axial bore in the intermediate shaft, which is likewise used for conducting the pressure fluid.
The countershaft can also form the output side or output element of the clutch device and correspondingly form a clutch device for engaging the transmission input and/or a further clutch device, for example a dual clutch device, or for coupling the rotor of the electric rotating machine in a rotationally fixed manner. The output element of a further possible device or clutch device for coupling to the intermediate shaft as the output side can be a torque converter.
The pressure space has substantially the shape of a hollow cylinder in cross section. The inner radius of the hollow cylinder is preferably smaller than the distance of the mechanical coupling of the clutch disk to the intermediate hub with respect to the axis of rotation.
The outer radius of the hollow cylinder can be greater than the distance of the mechanical contact of the pressure plate on the pressure tank from the axis of rotation. Alternatively or simultaneously, the outer radius of the hollow cylinder can also be greater than the distance of the driving ring gear of the intermediate hub for engaging the vibration damper with respect to the axis of rotation.
In other words, the pressure space may extend in the radial direction more radially outward than a radially innermost position of the pressure plate and/or may extend more radially outward than a radial position of the driving ring gear.
The pressure space may extend more radially inwards than the clutch disc.
The clutch device according to the invention has the advantage that the additional bearing between the piston-cylinder unit and the pressure plate can be dispensed with by the pressure pot rotating together.
By the piston-cylinder unit, which provides the operating force for the pressure plate, being formed by the pressure tank as a piston and by the housing as a cylinder, no relative rotation takes place between the pressure plate and the piston. The transmission of the actuating force for actuating the clutch device can thus be transmitted directly from the pressure tank to the pressure plate.
Furthermore, the pressure pot realizes a large axial surface which can be acted upon by the pressure caused by the pressure fluid, so that a large axial force for closing the clutch device can be realized by means of the pressure pot.
Furthermore, according to the invention, a hybrid module for a motor vehicle for coupling an internal combustion engine is provided, which has a clutch device according to the invention and an electric rotating machine, wherein a rotor of the electric rotating machine is coupled in a rotationally fixed manner to a driven side of the clutch device.
In one embodiment of the hybrid module, the hybrid module is designed for coupling a transmission.
This means that the rotor and/or the transmission of the electric rotating machine are coupled with the intermediate shaft.
For mounting the intermediate shaft, a support bearing, which is designed as a roller bearing, for example, can be provided here, which supports the intermediate shaft at a hybrid module housing wall of the hybrid module housing. The hybrid module housing wall is arranged in particular axially between the clutch device and the electric rotating machine, so that the clutch device and the electric rotating machine are spatially separated from one another. Furthermore, the clutch disk and the pressure pot are arranged substantially axially between the damper and the hybrid module housing wall.
The hybrid module can furthermore have a sensor unit for detecting the angular position and/or the rotational speed of the rotor of the electric rotating machine. The sensor unit comprises a transmitter element and a sensor element, wherein one of the two elements is connected in a rotationally fixed manner to the hybrid module housing and the respective other element is connected at least indirectly in a rotationally fixed manner to the rotor of the electric rotating machine.
By the rotationally fixed coupling of the rotor to the intermediate shaft, which in turn is connected rotationally fixed to the housing of the clutch device, it can be provided that one of the elements of the sensor unit, i.e. the transmitter element or the sensor element, is connected to the housing of the clutch device and the respective other element of the sensor unit is connected to a hybrid housing wall of the housing of the hybrid module. In particular, the sensor unit can thus alternatively be arranged on the side of the hybrid module housing wall facing the electric rotating machine on the side of the hybrid module housing wall facing the clutch device.
In a preferred embodiment, the device coupled to the output side of the clutch device is supplied with fluid, so that a fluid line can be used to supply fluid to the device or to drain it in order to supply pressurized fluid to the clutch device for actuating the clutch device. Thus, the additional fluid line can be dispensed with.
Furthermore, according to the present invention, there is provided a drive device for a motor vehicle, the drive device comprising: clutch device according to the invention and/or hybrid module according to the invention; a drive device, in particular an internal combustion engine; and a transmission, wherein the clutch device or the hybrid module is mechanically connected with the drive device via a drive side of the clutch device and with the transmission via a driven side of the clutch device.
Drawings
The invention described above is explained in detail below in the context of the relevant art with reference to the associated drawings, which show preferred embodiments. The invention is not limited in any way by the pure schematic figures, wherein it is to be noted that the embodiments shown in the figures are not limited to the dimensions shown. In which is shown:
fig. 1 shows a partially sectioned side view of a drive device according to the invention with a hybrid module according to the invention and a clutch device according to the invention.
Detailed Description
The detail here shows only a part of the hybrid module housing 70 of the hybrid module and the clutch device 1 according to the invention.
The clutch device 1 includes a damper 30, an intermediate hub 40, a clutch disc 10, a pressing device 20, a housing 4, and an intermediate shaft 50.
The vibration damper 30 forms the drive side 2 of the clutch device 1 and serves to engage the internal combustion engine of the drive device, wherein the intermediate shaft 50 forms the driven side 3 of the clutch device 1 and is mechanically connectable to the transmission of the drive device and to the electrical rotating machine of the hybrid module.
The output element 31 of the damper 30 has an internal toothing 32 and is connected in a rotationally fixed manner via said internal toothing to the toothing 41 of the intermediate hub 40. The intermediate hub 40 also forms a further toothing 42, by means of which it is connected to the clutch disk 10. The toothing 42 of the intermediate hub 40 forms a driving ring with an external toothing, into which the internal toothing 32 of the output element 31 of the damper 30 engages in a rotationally fixed manner. The pivot bearing 80 supports the intermediate hub 40 at the housing 4 of the clutch device 1.
For connection to the intermediate hub 40, the clutch disk 10 comprises a friction lining carrier 12 with internal toothing 13, by means of which the friction lining carrier 12 engages in a further toothing 42 of the intermediate hub 40, which is designed as an external toothing. In the radial direction, friction linings 11 are arranged on the outer side of the rotational axis 6 of the clutch device 1 on the friction lining carrier 12 and on both sides in the axial direction. The friction lining 11 of the clutch disk 10 is here arranged axially between the pressure plate 21 and the counter-pressure plate 22 of the pressure device 20.
The pressing device 20 furthermore comprises a pressure tank 23, wherein the pressure plate 21, the counter-pressure plate 22 and the pressure tank 23 are arranged in the housing 4 of the clutch device 1 and are connected thereto. The counter plate 22 is arranged on the axial side of the clutch disk 10 facing the damper 30 and is connected in a rotationally fixed manner to the housing 4 of the clutch device 1. On the side of the counter plate 22 axially opposite the clutch disk 10, a securing ring 25 is provided which is connected to the housing 4 and fixes the axial position of the counter plate 22 and via which a contact pressure acting axially on the counter plate 22 when closing the clutch device 1 is supported at the housing 4.
The pressure plate 21 is arranged on the side of the clutch disk 10 facing axially away from the damper 30 and is connected in a rotationally fixed manner to the housing 4 of the clutch device 1 via a plurality of leaf springs 24. The leaf spring 24 serves to transmit a torque from the pressure plate 21 to the housing 4 and/or to axially reset the pressure plate 21, which is moved in the direction of the clutch disk 10.
The housing 4 encloses the pressure pot 23 in the radial and axial direction, wherein the pressure pot 23 directly bears against the housing 4 radially on the inside and radially on the outside and is axially displaceable relative to the housing 4. The housing 4 furthermore forms a wall 5 of the housing 4 on the side of the pressure tank 23 facing axially away from the vibration damper 30, which wall extends along a section of the contour of the pressure tank 23 adjacent thereto in substantially the radial direction.
The abutment of the pressure tank 23 on the housing 4 enables the pressure tank 23 to be brought about in a friction-fit manner during the rotational movement of the housing 4.
The pressure plate 21 is axially seated on the pressure pot 23 on the side of the pressure pot 23 axially opposite the wall 5 of the housing 4.
The wall 5 of the housing 4 and the pressure tank 23 delimit a pressure space 60 for accommodating a pressure fluid, wherein a radial recess 62 with a sealing ring 61 arranged therein is provided in each case in the housing 4 both at the radially outer contact of the pressure tank 23 on the housing 4 and also at the radially inner contact of the pressure tank 23 on the housing 4, so that a high tightness of the pressure space 60 is ensured.
The pressure space 60 is in fluid connection with a first flow channel 63 formed in the housing 4. The first flow channel 63 is here guided in a substantially radial direction through the housing 4 in the direction of the intermediate shaft 50. The housing 4 of the clutch device 1 is arranged on the intermediate shaft 50 and is connected in a rotationally fixed manner to the intermediate shaft 50 via a plug-in toothing 51. A second flow channel 64 is formed in the intermediate shaft 50, which second flow channel is in flow connection with the first flow channel 63. The second flow duct 64 corresponds here to a bore extending radially through the intermediate shaft 50, an axial bore 65 being arranged radially centrally in the intermediate shaft 50, said axial bore being flow-coupled to the second flow duct 64. A flow connection is thus realized between the axial bore 65 and the pressure space 60 for conveying pressure fluid into the pressure space 60 and/or out of the pressure space 60.
The intermediate shaft 50 is mounted at a radially inner end of the hybrid module housing wall 71 by means of a support bearing 81, which is arranged on the intermediate shaft 50 on the side of the second flow channel 64 axially opposite the plug toothing 51.
Furthermore, the intermediate shaft 50 forms a connection region 52 on the side of the hybrid module housing wall 71 axially opposite the clutch device 1 for at least indirectly and rotationally fixed coupling of the intermediate shaft 50 to the rotor of the electric rotating machine of the hybrid module of the drive and to the input element of the transmission of the drive. The closing of the clutch device 1 is effected in such a way that the pressure fluid is conducted through an axial bore 65 in the intermediate shaft 50 into a second flow channel 64 in the intermediate shaft 50, from where it flows into a first flow channel 63 in the housing 4 of the clutch device 1 and subsequently into the pressure space 60. The pressure built up by the pressure fluid in the pressure space 60 now displaces the pressure tank 23 relative to the housing 4 in the axial direction away from the wall 5 of the housing 4. The pressure plate 21, which is applied directly on the pressure tank 23, is correspondingly axially displaced by means of the pressure tank 23 or pushed by it. The pressure plate 21 is thereby pressed against the clutch disc 10 and the clutch disc 10 is in turn pressed against the counter plate 22 so that a friction-fit connection between the clutch disc 10 and the pressure plate 21 and the counter plate 22 is achieved. The torque transmission path between the drive side 2 of the clutch device 1 and the driven side 3 of the clutch device 1 is therefore closed.
With the clutch device 1 according to the invention, when it is closed, a torque is thus transmitted between the drive side 2 of the clutch device 1 and the output side 3 of the clutch device 1. This means that the torque provided by the internal combustion engine can be transmitted via the clutch device 1 to the electric rotating machine and to the transmission, for example in order to drive a motor vehicle provided with a drive and/or to operate the electric rotating machine in charging mode, and the torque provided by the electric rotating machine can be transmitted via the clutch device 1 to the internal combustion engine, for example in order to start the internal combustion engine with the aid of the electric rotating machine.
Since the pressure vessel 23 is designed to rotate together, additional operating bearings between the force-exerting element and the pressure plate 21 can be dispensed with. Furthermore, the pressure pot 23 can be provided with a correspondingly large surface, so that a high axial pressing force can be exerted by the pressure pot 23.
With the help of according to the utility model discloses a clutch device, according to the utility model discloses a hybrid module and according to the utility model discloses a drive arrangement can ensure effectual and reliable use with the mode that the structure is simpler and more practice thrift the structure space.
