Friction clutch or brake having a friction element comprising a sheet metal support and a deposition of sintered friction material.

摘要

1. Friction clutch or friction brake, in particular a synchronizing ring (4) with lubricated friction surfaces which are not flat and/or which connot be developed geometrically, a separatetly premanufactured friction body (1) being employed for the friction surface, this friction body preferably being applied to a metal base body in a manner such that it is secured by material-to-material bonding by positive mechanical engagement, or by non-positive frictional engagement, characterized in that the friction body (1) is shaped from a backing plate with a friction coating which has been produced thereon by powder-application and in-situ sintering, and which has been compacted by means of a pressing treatment that may be repeated at least once.
