Process of manufacturing a friction ring for use in a clutch or brake

摘要

A process is described for manufacturing a friction ring for use in a clutch or brake. Said friction ring comprises a sintered friction lining that is provided on at least one peripheral surface of a conical or cylindrical carrying ring, which has been formed from a flat sheet metal blank after a coating comprising a sinterable powder mixture has been formed on the flat sheet metal blank. In order to permit a shaping of the sheet metal blank independently of the ductility of the sintered friction lining, it is proposed that the sinterable powder mixture for making the friction lining is mixed with an expellable synthetic resin binder before said mixture is applied to the flat sheet metal blank to form said coating, said coating is set, the sheet metal blank provided with said coating is shaped to form the friction ring when said coating has been set, and the friction lining is subsequently sintered while or after the synthetic resin binder is expelled at least in part.
