Abstract
A friction energizing drive such as a clutch disc in a friction clutch for automotive clutches, starting clutches for continuously variable transmissions and heavy-duty clutches for heavy equipment or off-the-road vehicles, wherein a ceramic material in the form of discs or buttons comprise the friction material. To smooth the generally abrupt torque curve and reduce the harsh feel of a ceramic material clutch, the ceramic material in the form of circular members, alone or secured to disc backings, are rotatably mounted on an annular clutch disc or plate located between a flywheel and pressure plate in a clutch assembly.
