Abstract

An engaging and disengaging clutch includes a clutch disk having friction linings on each of two sides thereof, the friction linings being made from an organically bound friction material; a counterrotating member and a pressure plate both disposed adjacent the clutch disk; and a friction element disposed on at least one of the counterrotating member and the pressure plate and defining a friction surface being made from a sintered metal material. The sintered metal material contains therein any heavy components adapted for use in the friction linings of the clutch disk and in the friction element for achieving an optimum friction pairing therebetween, the organically bound friction material thereby being free of the heavy components.
