Abstract

The clutch disc for a motor vehicle friction clutch comprises a friction damper with friction linings resiliently braced in axially between disc parts. The friction linings have surface regions with different coefficients of friction which can be brought into operative engagement according to choice by control means for the adjustment of the friction torque of the friction damper. In this way the friction torque can be adjusted for the compensation of construction tolerances of the clutch disc, without variation of the spring stress of the friction damper.
