Multiple Disc Clutch

Abstract

A multi-disc clutch, in particular a two-disc clutch, having a counter plate (22), a clutch disc (32) with a first lining ring (28) and a second lining ring (30) and having an intermediate plate (34 ), wherein, there are n intermediate plates (34) and n+1 lining rings (28, 30), wherein the movement of the intermediate plate and the movement of the extrusion plate pass through the coupling mechanism (44) along the Coupling in the axial direction, wherein at least between the open position of the pressure plate corresponding to the open position of the multi-disc clutch and the maximum closed position of the pressure plate corresponding to the closed position of the multi-disc clutch when the lining rings are worn Current travel of the axial displacement of the compression plate relative to the axial displacement of the intermediate plate furthest away from said compression plate in the axial direction at the axial position SA of the compression plate in the section section The conversion ratio i(SA) deviates from i(SA)=n+1, and / or in the case of the axial position SA of the squeeze plate, the axial displacement of the squeeze plate relative to the axial direction of the j-th intermediate plate The shifted current stroke conversion ratio i(SA)j deviates from i(SA)j=(n+1) / j, where j is counted from the corresponding plate towards the squeeze plate. Through the stroke conversion ratio of the coupling mechanism deviating from n+1, the multi-disc clutch can be easily adapted to different design dimensions of the lining ring and / or to the desired different operating modes, so that particularly high torque transmission is possible In various designs of the drive train of the motor vehicle, this is achieved 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...

In addition, multi-plate clutches are mostly not properly vented when the friction points between the plates and the plate carrier are not lubricated by oil
