Description

Clutch device and hybrid module
Technical Field
The present invention relates to a clutch device according to the preamble of claim 1. The invention further relates to a hybrid module according to claim 10.
Background
A clutch device is known, for example, from DE 102018101019 a 1. A hybrid module is described, which has a plurality of clutches that can be actuated separately from one another and a clutch carrier that accommodates the clutches. The electric motor is connected to the clutch carrier via a drive device, which is embodied separately from the clutch carrier and is supported in the transmission housing via a further bearing.
Disclosure of Invention
The aim of the invention is to improve the mounting of a clutch device. Furthermore, the clutch device should be inexpensive to implement. The clutch device should enable a stronger vibration decoupling. Furthermore, a hybrid module having such a clutch is proposed.
At least one of these tasks is solved by a clutch device having the features according to claim 1. This improves the support of the clutch device and makes it possible to implement the clutch device more inexpensively. The clutch stator associated with the first clutch element can be dispensed with. The bearing tolerance can be reduced. By means of such a one-sided mounting of the clutch device, a reliable guidance of the first clutch element can be achieved, which in turn contributes to the vibration behavior and efficiency of the electric motor.
The clutch device can be embodied to be wet-running. The clutch device may have a second clutch having a third clutch element which can be rotated about a rotational axis, a fourth clutch element and a second friction region which is arranged to act between the third and fourth clutch elements and is used for a releasable friction-locking connection between the third and fourth clutch elements. The first and third clutch elements can be connected to one another, in particular rotationally fixed (drehfest). The first clutch element may be embodied in one piece with the third clutch element. The first, second, third and/or fourth clutch element can be embodied as an inner diaphragm carrier or as an outer diaphragm carrier.
The first drive device may be embodied as an internal combustion engine. The driven device may be embodied as a transmission.
The first and second clutches may be arranged to act in series. The fourth clutch element can be connected in a rotationally fixed manner to a driven element of the output, for example to the transmission input shaft. The second clutch element can be connected in a rotationally fixed manner to a drive element of the first drive, for example to a drive shaft. The second clutch may be arranged to act between the second drive means and the driven means.
The first and second clutches may be arranged axially side by side. The second clutch can also be supported at least radially on the receiving housing only via the first clutch element, which is supported on the housing element by the bearing arrangement.
A torsional vibration damper, for example a dual mass flywheel, can be connected upstream of the clutch device. The bearing device may be arranged axially between the torsional vibration damper and the first friction region or axially between the output device and the first friction region. This may result in an improved decoupling between the first drive and the output. In particular, damping and isolation of radial and/or axial vibrations triggered by the first drive device may be enhanced.
The first and/or second clutch can be actuated completely hydraulically. The housing element can have a fluid opening for the introduction of a pressure fluid for actuating the first and/or second clutch.
The first and/or second bearing elements may be deep groove ball bearings. The first and/or second bearing elements may be thrust needle bearings.
The first and/or second clutch and the rotor may be supported at least in the axial direction via a support device.
In a preferred embodiment of the invention, there is no component for torque transmission in the axial intermediate region between the first and second bearing elements. This makes it possible to achieve a more reliable and more cost-effective support.
In a particular embodiment of the invention, the rotor is arranged concentrically with the first clutch element. The installation space can thereby be reduced.
In a preferred embodiment of the invention, the first and second bearing elements are arranged radially within the first friction region. The first and second bearing elements may be arranged radially at the same level or radially offset from one another.
In a particular embodiment of the invention, the first clutch element has a fluid opening for the passage of fluid. These fluid openings may be arranged axially between the first and second bearing elements. The fluid may be a pressure medium for operating the first and/or second clutch. The fluid may be a cooling fluid for cooling the first and/or second clutch. The housing element can have fluid openings for the fluid to flow through, which are each connected to a fluid opening in the first clutch element.
In a preferred embodiment of the invention, the first clutch element extends radially within the housing element in the region of the bearing device.
In a particular embodiment of the invention, the first clutch element is embodied as a rotor carrier, and the rotor is connected to the first clutch element in a rotationally fixed manner and is accommodated thereon. The rotor can thereby be radially supported on the housing element via the bearing device with reduced bearing tolerances.
In a preferred embodiment of the invention, the rotor is arranged radially outside the first friction region. Thereby improving the torque capacity of the electric motor.
In a preferred embodiment of the invention, the first clutch element is arranged radially outside the drive element, which is connected in a rotationally fixed manner to the second clutch element, and/or radially outside the driven element of the driven device. The first clutch element and the drive element and/or the driven element may be axially stacked.
In order to solve at least one of the above-mentioned objects, a hybrid module is furthermore proposed, which has an electric motor embodied as a second drive device, which has a stator and a rotor which is rotatable relative to the stator, and which has a clutch device having at least one of the above-mentioned features.
Further advantages and advantageous embodiments of the invention result from the description and the illustration of the figures.

The present invention is described in detail below with reference to the accompanying drawings. Wherein in detail:
FIG. 1: a half section of a hybrid module with a clutch device in a particular embodiment of the invention is shown;
FIG. 2: a half-section of a hybrid module with a clutch device is shown in a further particular embodiment of the invention.
Detailed Description
Fig. 1 shows a half-section of a hybrid module 10 with a clutch device 12 in a particular embodiment of the invention. The hybrid module 10 is arranged in a drive train of a motor vehicle between a first drive, in particular an internal combustion engine, and a driven element, in particular a transmission.
The hybrid module 10 comprises a second drive 16, which is designed as an electric motor 14. The electric motor 14 includes: a stator 20 firmly connected to the stationary receiving housing 18 and a rotor 22 rotatable relative to the stator along a rotation axis a. The rotor 22 is arranged radially inside the stator 20. Furthermore, the hybrid module 10 comprises a clutch device 12 having a first clutch 24 and a second clutch 26 connected in series with the first clutch. The first and second clutches 24, 26 are embodied wet-running.
The first and second clutches 24, 26 are arranged together with the rotor 22 and the stator 20 on one side of a housing element 28 which is firmly connected to the receiving housing 18. The housing element 28 has a substantially radially extending section 30, with an axially extending section 32 coupled to the section 30 at a radially inner portion. A drive element 34 of a first drive device, which is mounted on a first clutch element 38 via two radial needle bearings 36, is guided radially within the housing element 28.
The first clutch element 38 is designed in two parts and has a radially inner first clutch part 38.1 and a radially outer second clutch part 38.2 connected in a rotationally fixed manner to the first clutch part. The first clutch element 38 is embodied as a rotor carrier. The rotor 22 of the electric motor 14 is accommodated here on the second clutch part 38.2 and is connected in a rotationally fixed manner to it. On the motor side, a rotor position sensor 40 is arranged on the rotor 22.
The first clutch element 38 and the second clutch element 44 can be releasably frictionally connected via the first friction region 42. The second clutch element 44 is embodied as an inner diaphragm carrier and is formed integrally with the drive element 34. Actuation of the first clutch 24 takes place via a first clutch piston 46, which can be moved apart against the action of a first return spring element 50 (here a disc spring) by means of a fluid pressure of the fluid in a first pressure chamber 48 in the direction of the first friction area 42. The return spring element 50 can also be embodied as a helical spring.
The first clutch 24 is arranged axially next to the second clutch 26, which has a third clutch element 52 and a fourth clutch element 56 which can be releasably connected to the third clutch element via a second friction region 54. The first clutch element 38 and the third clutch element 52 are embodied in one piece with one another. The second clutch part 38.2 assigned to the first clutch element 38 comprises an internal toothing in which the friction diaphragms of the respective first and second friction regions 42, 54 are suspended in an axially displaceable manner.
The fourth clutch element 56 is embodied as an inner diaphragm carrier and is connected to a driven element 58 of the driven device. Driven element 58 may embody a transmission input shaft. The actuation of the second clutch 26 takes place via a thrust element 60, which passes axially through the first clutch 24 and is connected to a second clutch piston 62, which can be deflected against the restoring force of a second restoring spring element 66 (here a disk spring) via the fluid pressure of the fluid in a second pressure chamber 64. The second restoring spring element 66 can also be embodied as a helical spring.
The first and second clutches 24, 26 can be actuated as fully hydraulic clutches via the fluid pressure present in the first and second pressure chambers 48, 64. The fluid pressure is caused by the fluid which can be fed via the fluid opening 68 in the first clutch part 38.1 of the first clutch element 38. The fluid opening 68 of the first clutch element 38 is coupled here to a fluid opening 70 in the housing element 28, which is supplied with fluid. In addition to the clutch actuation pressure provided via the fluid, one of the fluid openings 70 is also used to deliver cooling fluid for cooling the first and second clutches 24, 26. The further fluid opening 70 is also arranged in the first clutch element 38 and the housing element 28.
A seal 72 between the drive element 34 and the housing element 28 effects a seal against an interior space 74 formed by the receiving housing 18 for receiving the cooling fluid. The first pressure chamber 48 is delimited by the first clutch piston 46 and the seal retainer 75. A centrifugal force compensation chamber 76 is arranged on the side of the first clutch piston 46 axially opposite the first pressure chamber 48. The second pressure chamber 64 is delimited by the second clutch piston 62 and a seal retainer 80 which is axially secured to the first clutch element 38 via a snap ring 78. Opposite the second pressure chamber 64 is a further centrifugal force compensation chamber 82.
The first clutch 24 is preferably designed to disconnect the first drive element from the subsequent drive train, in particular from the driven element 58. The second clutch 26 may cause disengagement of the driven member 58 from the electric motor 14. The rotor 22 is arranged concentrically with the first clutch element 38.
The first and second clutches 24, 26 and the rotor 22 are supported radially on the stationary receiving housing 18[ YJ1] exclusively via the first clutch element 38 and the bearing arrangement 84 on the housing element 28. The bearing arrangement 84 comprises a first bearing element 84.1 accommodated directly on the housing element 28 and a second bearing element 84.2 arranged axially spaced apart from the first bearing element and accommodated directly on the housing element 28. This improves the support of the clutch device 12, and makes it possible to implement the clutch device 12 at low cost. The clutch stator assigned to the first clutch element 38 can be dispensed with. The bearing tolerance can be reduced. A reliable guidance of the first clutch element 38 can be achieved by the one-sided mounting of the clutch device 12, which in turn contributes to the vibration behavior and the efficiency of the electric motor 14.
The first and second bearing elements 84.1, 84.2 are embodied as deep-groove ball bearings, and the axial intermediate region 85 between the first and second bearing elements 84.1, 84.2 is free of components which transmit torque. The first and second bearing elements 84.1, 84.2 are arranged radially within the first and second friction areas 42, 54. The first clutch element 38 is arranged radially within the housing element 28 in the region of the bearing 84. The rotor 22 is arranged radially outside the first and second friction areas 42, 54.
The bearing means 84 also causes a support in the axial direction towards the first drive means. In the opposite axial direction, the clutch device 12 can be axially supported on the driven element 58. The axial spacing required here can be provided via an adjusting washer.
The output element 58 is arranged within a housing wall 86 associated with the receiving housing 18. The clutch device 12 is arranged axially between the housing wall 86 and the first housing element 28. The housing wall 86 and the housing element 28 are firmly connected to one another here.
Fig. 2 shows a half-section of a hybrid module 10 with a clutch device 12 in a further particular embodiment of the invention. The bearing arrangement 84 is arranged here on the housing element 28 arranged on the output side with respect to the first clutch 24 and the second clutch 26.
The first and second clutches 24, 26 are arranged axially between the housing element 28 and the drive-side clutch cover 88. The clutch cover 88 is sealed with respect to the drive element 34 of the first drive device via a seal element 90. The clutch cover 88 is associated in a rotationally fixed manner with the receiving housing 18, which also receives the stator 20 of the electric motor 14, and can be embodied as a sheet metal component.
The first and second bearing elements 84.1, 84.2 are embodied as radial needle bearings, but can also be deep groove ball bearings, respectively. The first and second clutches 24, 26 and the rotor 22 of the electric motor 14 are supported radially on the receiving housing 18 only via a bearing 84 arranged between the housing element 28 and the first clutch element 38. The housing element 28 has an axial section 32, in particular a clutch bell base, and the bearing 84 is arranged on this section 32.
The clutch device 12 is axially supported on the clutch cover 88 in the axial direction via a thrust needle bearing 90 or a thrust washer. Two thrust needle bearings 92 are arranged between the second clutch element 44, the fourth clutch element 56 and the first clutch element 38. In the opposite axial direction, the clutch device 12 is supported via an adjusting washer 94 between the first clutch element 38 and the driven element 58. The axial play can be adjusted via the adjusting washer 94 for compensating for the deformation. Alternatively, the axial bearing can also be carried out via the bearing device 84, which for this purpose preferably has at least one deep groove ball bearing. Alternatively or additionally, at least one thrust washer and/or at least one thrust needle bearing may also be arranged between the first clutch element 38 and the housing element 28.
The output element 58 of the output device is arranged radially within the first clutch element 38 and is connected in a rotationally fixed manner to the fourth clutch element 56. The first clutch element 38 is arranged radially within the axial section 32 of the housing element 28.
The first and second return spring elements 50, 66 are preferably embodied as helical springs, but can also be embodied as disk springs. The supply of the pressure fluid and the cooling fluid takes place via the transmission-side housing element 28, which for this purpose has a fluid opening 70. Due to the fact that the alignment of the transmission side and the line length to the transmission hydraulic system are small, pressure losses during fluid supply can be reduced. Furthermore, costs can be reduced due to simpler line guidance.
The fluid opening 70 in the housing element 28 is connected to the fluid opening 68 in the first clutch element 38, from which the pressure fluid and the cooling fluid are conducted into the clutch device 12. The cooling fluid flows along the cooling fluid flow 96 to cool the first and second clutches 24, 26. The common cooling fluid flow 96 may act on the first and second clutches 24, 26.
The hybrid module 10 can be inserted as a preassembled unit into the receiving housing 18, in particular the entire transmission housing, which receives the stator 22. The rotor position sensor 40 is arranged radially between the housing element 28 and the first clutch element 38, which is embodied as a rotor carrier, and can be embodied as an eddy current sensor.
