Embodiment Construction

[0072] First of all, according to figure 1 The general structure of the hybrid module according to the invention is explained.

[0073] The hybrid module is designed for connection to the crankshaft 1 of an adjoining (not shown in the drawing) internal combustion engine system. For this purpose, a dual-mass flywheel 2 is usually used, which is connected in a rotationally fixed manner to the crankshaft 1 and to the disconnect clutch 10 of the hybrid module.

[0074] In this case, the counterpressure disk 11 of the disconnect clutch 10 is connected in a rotationally fixed manner to the dual mass flywheel 2 . Counter pressure plate 11 is mounted on countershaft 80 or on crankshaft 1 by means of support bearing 12 .

[0075] The disconnect clutch 10 is formed substantially by a counter pressure plate 11 as well as a pressure plate 13 and at least one clutch disc 15 positioned between the pressure plate 13 and the counter pressure plate 11 . Furthermore, the disconnect clutch 10...

Abstract

The invention relates to a clutch device as well as a hybrid module and a drive for a motor vehicle. The clutch device is in particular a disconnect clutch (10) and comprises a clutch disc (120, 220, 230) and a pressing element (201, 211, 212) for loading the clutch disc with a pressing force ( 120, 220, 230) for friction-fit transmission of torque between said pressing element (201, 211, 212) and said clutch disc (120, 220, 230). The pressing elements (201, 211, 212) are odd in number and are axially displaceable. One of the clutch discs (120) is fixed axially. The clutch device is designed such that an axially acting force (240) can be introduced into at least one of the pressing elements (201, 211, 212) for generating a pressing force and can be transferred from the pressing element Applied as a compressive force on the clutch discs (120, 220, 230). As a reaction to a pressing force directed against said clutch disc, the axially fixed clutch disc (120) can be supported axially by means of a supporting force (250) directed against said pressing force, wherein said axial Both the acting force ( 240 ) and the supporting force ( 250 ) are supported at rotationally fixed elements of the clutch device, in particular at a supporting wall ( 21 ) of the clutch device. The clutch arrangement and the hybrid module combine energy-efficient operation with a reduced axial load on the connected unit.

Description

technical field [0001] The invention relates to a clutch device and a hybrid module with the clutch device for coupling to an internal combustion engine for a motor vehicle, such as a passenger car, a van or another commercial vehicle, and to a motor vehicle with the clutch device according to the present invention Invented drive unit for the hybrid module. Background technique [0002] Clutch arrangements or clutches are well known. The clutch device or clutch is designed to transmit torque between clutch elements, for example between a pressure plate and a clutch plate, mostly frictionally. In this case, the clutch device or the clutch opens and closes the torque transmission path as required. In this case, the corresponding force for adjusting the clutch element can be varied. Correspondingly, the components coupled to the clutch arrangement are subjected to different loads. [0003] The hybrid module generally comprises a coupling device for mechanically coupling the...
