Abstract

To enable prescribed functional values of pressure plate units of motor vehicle friction clutches to be observed with smaller tolerances than hitherto, it is proposed that a housing-spring component initially be pre-assembled from clutch housing (1) and diaphragm spring (7) and that this component be measured together with a master pressing plate. Geometry (diameter 25 and axial height 27) which is optimum for minimum tolerances of a contact bevel 15 is calculated by means of the measured result, and a pressing plate (13) with this bevel geometry is produced. The measured spring-housing component is finally assembled together with this specially produced pressing palte 913).
