Abstract
A friction lining (5) for a device which is cooled with fluid or lubricant and is intended for transferring torque, in particular a friction clutch, synchronizing element or brake, the friction lining being fastened on a carrier body (2) in order to form a friction surface (6) and the torque being transferred to a counter-surface, is constructed from at least two different layers, and in particular from at least one porous substrate (11, 11') which is fastened on the carrier body (2) and which is constructed like a composite material from a cellulose base with synthetic fibers and filler, and from a porous friction layer (12) which is fastened on the substrate (11,11') and is made of synthetic fibers, preferably carbon, which are bonded with a thermoset resin.
Claims18
A fluid-cooled friction lining for attachment to a carrier body in a torque-transferring device, the friction lining including a friction surface facing away from the carrier body, the friction lining comprising a porous substrate layer which can be bonded to the carrier body and which includes a mixture of cellulose and synthetic fibers, filler and a thermoset resin, and a porous friction layer which provides said friction surface and which includes a mixture of non-woven synthetic fibers in a thermoset resin, said substrate layer having a weight from 200 to 1500 g/m.sup.2 and said friction layer having a higher porosity than said substrate layer.
