Sheet metal pressure plate and pressure pot as joint component

Abstract

The invention relates to a clutch for a motor vehicle, having a pressure plate which is set up to clamp a torque transmission member, such as a disk or friction disk, together with a counterpressure plate, wherein a force transmission path is provided between an actuating unit via a pressure transmission member, wherein the pressure transmission member is configured as an integral part of the pressure plate. The invention also relates to a method for producing a pressure plate for a clutch, wherein the pressure plate is formed with an integrated pressure transmission member from a sheet metal plate via a chipless forming process.

1 . A clutch for a motor vehicle, comprising a pressure plate adapted for clamping a torque transmission member together with a counter-pressure plate, with a force transmission path being provided via a pressure transmission member to an actuator unit, wherein the pressure transmission member is an integral component of the pressure plate. 
     
     
         2 . The clutch according to  claim 1 , wherein the pressure plate is formed as a metal plate and includes a section providing the pressure transmission member. 
     
     
         3 . The clutch according to  claim 2 , wherein the metal plate is formed in a chipless fashion. 
     
     
         4 . The clutch according to  claim 2 , wherein the metal plate has a constant thickness or a reducing thickness towards a contact area of the pressure transmission member with the actuating unit. 
     
     
         5 . The clutch according to  claim 2 , wherein the metal plate comprises a spring-elastic section. 
     
     
         6 . The clutch according to  claim 1 , wherein the pressure plate comprises a friction area adapted to cooperate with at least one of the torque transmission member or an actuator group. 
     
     
         7 . The clutch according to  claim 1 , wherein the pressure transmission member is perforated by recesses in order to allow a supply of cooling fluid in a direction of the torque transmission member. 
     
     
         8 . The clutch according to  claim 1 , wherein a spring element engages the pressure plate acting primarily in an axial direction. 
     
     
         9 . The clutch according to  claim 1 , wherein individual parts are adjusted and arranged in reference to each other such that in a slippage phase energy is absorbed. 
     
     
         10 . A method for producing a pressure plate for a clutch, comprising forming the pressure plate from a metal plate via a chipless formation process with a pressure transmission member integrated therein. 
     
     
         11 . The clutch according to  claim 2 , wherein the pressure transmission member is embodied like a tongue.
