Abstract
The pressure plate actuation fingers of a friction clutch are provided with means for noise attenuation by the application of acoustical materials, alteration of the mass of vibrating parts, or surface treatment of slipping parts either individually or collectively to prevent the generation of objectionable noise due to resonance and sympathetic vibrations that are initiated by the stick-slip phenomenon as the non-rotating clutch release bearing contacts the relatively rotating actuation fingers.
