Embodiment Construction

[0035] 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

According to the invention, an intermediate plate (34) is proposed for a multi-plate clutch (20), especially a double-plate clutch, in particular for a double clutch (10) and for connecting a motor vehicle engine The drive shaft (12) is coupled with at least one transmission input shaft (16, 18) of the motor vehicle transmission, and the intermediate plate has: an annular body (48) for being pressed into the drive shaft (12) with a friction fit ) between the counter pressure plate (22) coupled and the pressure plate (26) that can move axially relative to the counter pressure plate (22); It is used to couple the ring body (48) with the pressure plate (26) in a stroke transmission mode, wherein the contact piece (46) has a contact body (42) protruding in the axial direction, which is used for the axial stop in the especially On the return spring (38) configured as a leaf spring, the contact body is formed by plastic deformation of a part of the contact lug (46), said return spring is connected to the pressure plate ( 26) or other intermediate board connections. Through the contact body (42) formed by the plastic deformation of the contact web (46), by means of the additional friction surface provided by the annular body (48), in the case of different structural forms of the drive train of the motor vehicle, by means of The friction clutch (20) achieves transmission of particularly high torques.

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...
