Abstract
A clutch and brake friction assembly for a heavy duty vehicle is provided which includes a metal shoe having an exterior backing surface. The surface is provided with a multitude of burr-like protuberances arranged in a predetermined pattern throughout the surface. Molded to the backing surface and mechanically interlocking with the burr-like protuberances thereof is a lamina of friction material.
Claims3
A clutch and brake friction assembly suitable for use on heavy duty vehicles such as over-the-highway trucks and the like comprising
- (a) a metallic shoe having an exposed continuous planar backing surface;
- (b) a first lamina overlying said backing surface and comprising a multitude of metallic fibers agglomerated in overlapping fashion and metallurgically fused to one another and to said backing surface so as to form a plurality of interstices and a multitude of protuberances outwardly-extending from said backing surface;
- and
- (c) a second lamina of friction material overlying said first lamina, juxtaposed portions of said second lamina filling said interstices and being mechanically interlocked with the outwardly-extending protuberances so as to secure said second lamina to said first lamina and said backing surface.
