AI Technical Summary

Problems solved by technology

This slight skew here leads to uneven loading of the balls, so that individual balls or parts of the raceway can be overloaded and damaged
This will lead to the impression that the life of the bearing is greatly reduced
[0004] Assembly of drive trains with such clutch assemblies is also difficult due to the required fit between the central bearing and the corresponding transmission input shaft
[0005] In addition, the machining of the fit required between the central bearing and the corresponding transmission input shaft also means an increase in manufacturing costs

Embodiment Construction

[0024] figure 1 The clutch assembly 1 shown in the figure comprises two friction clutches 2 , 3 which are shown in a disengaged state, ie in an open state. The clutch assembly 1 is part of the drive train of a motor vehicle, tractors, work machines, trucks, passenger cars and the like being understood by motor vehicles. The drive train connects the internal combustion engine to the driven wheels and includes, in addition to the clutch assembly, a parallel transmission and further transmission mechanisms such as shafts, differentials, and the like. The clutch assembly thus forms a double clutch comprising two clutch disks 4 , 5 which can be connected to different transmission input shafts.

[0025] The clutch disks 4 , 5 carry friction disks 6 , 7 radially on the outside, which can be clamped axially on the counter pressure disk 8 common to the two friction clutches 2 and 3 and which are assigned to the respective friction clutch 2 or 3 between the compression plates 9,10. ...

Abstract

The invention relates to a torque transmission device in the drive train of a motor vehicle, said torque transmission device being supported on a transmission input shaft (23) via a support bearing (27), wherein the transmission input shaft and the support bearing pass through a The directional positively engaging connection means are connected to one another.

Description

technical field [0001] The invention relates to a torque transmission device in a drive train of a motor vehicle, which is supported on a transmission input shaft via a support bearing. In particular, the present invention relates to a clutch assembly in a drive train of a motor vehicle, the clutch assembly having a pressure plate, a counter pressure plate and a clutch disc arranged between the pressure plate and the counter pressure plate, wherein the The counter pressure plate is mounted rotatably on the transmission input shaft by means of a support bearing, wherein the support bearing comprises a bearing inner ring and a bearing outer ring. Background technique [0002] A (double) clutch with such a bearing is known from DE 10 2005 037 514 . In this document, the bearing of the central plate (=the counter-pressure plate of the two single clutches of the dual clutch) is mounted or axially supported on one of the transmission input shafts by means of a so-called central b...
