ABSTRACT:
There is disclosed an improved automotive clutch in which the clutch diaphragm is supported by rotational bearings, preferably spherical balls which are carried in a circular groove on the upper surface of a raised rim on the pressure plate. In some applications the rotational bearings can also be provided at the fulcrum support for the diaphragm. In the pull-off type of clutch, the base of the diaphragm is supported by rotational bearings carried on the undersurface of the clutch housing cover, and additional rotational bearings are provided on a raised rim on the pressure plate. In either application, the rotational bearings can be spherical balls, or elongated rollers.
