ABSTRACT:
A friction clutch element is disposed for mounting to a rotatable clutch disc. The element is designed to improve the uniformity in coefficient of friction values over a friction surface area thereof during clutch operation, particularly when such surface is formed of ceramic material. The element includes friction facings having symmetrically disposed radially inner and outer subportions integrally joined by a center subportion of a circumferentially shorter dimension. The facings contain radially disposed, continuously arcuate leading and trailing edges, and in a preferred embodiment, the leading and trailing edge portions of the outer and inner subportions are convex, while those of the center subportion are concave.
