Embodiment Construction

[0052] figure 1 The dual clutch 10 shown in FIG. 2 can decouple a drive shaft 12 from a first transmission input shaft 16 and a second transmission input shaft 18 via a torsional vibration damper 14 designed as a dual-mass flywheel. For this purpose, a multi-disc clutch 20 is provided in each case, each having a corresponding plate 22 coupled to the drive shaft 12 and a pressure plate displaceable by means of an actuating element 24 designed as a rigid actuating pot 26, wherein, the pressing plate 26 can also press the middle plate 34, and the middle plate is arranged between the first lining ring 28 of the clutch disc 32 and the second lining that can move axially relative to the first lining ring 28 Between rings 30. For this purpose, an actuating force, in particular for closing the multidisc clutch 20 , can be introduced into the actuating element 24 by the hydraulic actuating element 36 . The pressure plate 26 is connected at least indirectly to the counter plate 22 via...

Abstract

The invention relates to a multi-disk clutch, in particular a two-disk clutch, comprising a counter plate (22), a clutch disk (32) having a first lining ring (28), a second lining ring (30) and an intermediate plate (34). A number of n intermediate plates (34) and a number of n+1 lining rings (28, 30) are provided, wherein the motion of the intermediate plate is coupled to the motion of the pressure plate by means of a coupling mechanism (44) in the axial direction. At least along a partial path between an opening position of the pressure plate corresponding to the open position of the multi-disk clutch and a maximum closing position of the pressure plate corresponding to the closed position of the multi-disk clutch in the event of worn lining rings, a current displacement transmission ratio i(sA) of the axial displacement of the pressure plate to the axial displacement of the intermediate plate furthest from the pressure plate in the axial direction deviates from i(sA) = n+1 in the event of an axial position sA of the pressure plate and / or a current displacement transmission ratio i(sA)j of the axial displacement of the pressure plate to the axial displacement of a j-th intermediate plate deviates from i(sA)j = (n+1 ) / j in the event of an axial position sA of the pressure plate, wherein j is counted from the counter plate in the direction of the pressure plate. By means of the displacement transmission ratio of the coupling mechanism deviating from n+1, the multi-disk clutch can be easily adapted to differently dimensioned lining rings and / or different intended operating modes such that the transmission of a particularly high torque is made possible for different designs of a motor vehicle drive train by means of a friction clutch.

Description

technical field [0001] The invention relates to a multi-plate clutch, in particular a two-plate clutch, by means of which a drive shaft of a motor vehicle motor can be coupled to at least one transmission input shaft, wherein the multi-plate clutch is especially suitable for dual clutches. Background technique [0002] According to the current state of the art, dry double clutches usually have one disk per partial clutch. These discs each have two friction surfaces, with which the discs bear against their adjacent components (such as the pressure plate and the central plate or the corresponding plate), if the discs are clamped by the clutch for torque transmission And thus these plates form two friction points with the clutch. The transmissible torque of the clutch can also be increased with the same pressing force, the same diameter and the same friction ratio (friction coefficient) by increasing the number of friction points. This principle is frequently used in multi-pl...
