Embodiment Construction

[0036] exist figure 1 The multi-disk dual clutch 10 shown in FIG. 2 is capable of coupling a drive shaft 12 via a torsional vibration damper 14 designed as a dual mass flywheel with a first transmission input shaft 16 and a second transmission input shaft 18 . For this purpose, a multiplate clutch 20 is provided in each case, which each has a counter pressure plate 22 coupled to the drive shaft 12 and a pressure plate 26 which is displaceable by means of an actuating element 24 designed as a rigid actuating pot, wherein The pressure plate 26 is also able to press an intermediate plate 34 which is arranged between the first backing ring 28 of the clutch disk 32 and the second backing ring 30 which is axially displaceable relative to the first backing ring 28 . For this purpose, an actuating force, in particular for closing the multi-plate clutch 20 , can be introduced into the actuating element 24 by the hydraulic actuating system 36 . The pressure plate 26 is connected at lea...

Abstract

The invention relates to an intermediate plate (34) for a multi-disk clutch (20), in particular a two-disk clutch. The multi-disk clutch is used for coupling a drive shaft (12) of a motor-vehicle motor to at least one transmission input shaft (16, 18) of a motor-vehicle transmission, in particular for a dual clutch (10). The intermediate plate comprises: an annular body (48) for pressing, in a friction-closed manner, between a counterplate (22) that can be coupled to the drive shaft (12) and a pressure plate (26) that can be axially displaced in relation to the counterplate (22); and a contact tab (46), in particular formed integrally with the annular body (48), for displacably coupling the annular body (48) to the pressure plate (26), wherein the contact tab (46) has a contact body (42), which is formed by plastically deforming part of the contact tab (46) and which protrudes in the axial direction, for axially stopping against a restoring spring (38), which is connected to a pressure plate (26) or further intermediate plate following the intermediate plate (34) in the axial direction and which is designed in particular as a leaf spring. By means of the contact body (42) formed by plastically deforming the contact tab (46), transmission of an especially high torque by means of a friction clutch (20) in the case of different structural forms of a drive train of a motor vehicle is enabled by means of the additional friction surfaces provided by the annular body (48).

Description

technical field [0001] The invention relates to an intermediate plate for a multi-plate clutch and a method for producing such an intermediate plate, which can be pressed between a counter-pressure plate and a pressure plate movable relative to the counter-pressure plate, so that This increases the number of friction contacts and the size of the entire friction surface of the multi-plate clutch, so that correspondingly high torques can be transmitted by means of the multi-plate clutch. Background technique [0002] According to the prior art, dry double clutches usually have one plate for each partial clutch. These disks each have two friction surfaces by means of which the disk rests against its adjacent component (for example pressure plate or center disk or counter-pressure plate) when the disk is clamped by the clutch for torque transmission, And then constitute two friction parts with clutch. The transmissible torque of the clutch can also be increased with the same p...
