Abstract
In accordance with one aspect of the present invention, a material for an element of a power transmission-absorption assembly and the method of making such material is disclosed. The material has a pre-selected channel configuration to permit flow of a cooling medium thereacross or therethrough.
Claims79
A friction facing material comprising:
- (a) a plurality of first yarns positioned in substantially parallel relationship to each other;
- and
- (b) a plurality of second yarns woven over and under said first yarns to form a texture having a plurality of plateaus and low points;
- said plurality of first yarns and said plurality of second yarns are woven to provide a plurality of channels or paths each of which comprise an entry and exit for channelling said cooling medium in a desired flow path.
1 more element
A friction power absorption or power transmission assembly comprising:
- (a) a first member;
- (b) a second member situated in opposed relationship to said first member;
- (c) a friction facing material affixed to one of said first and second members, said friction facing material comprising:
- (1) a plurality of fill yarns positioned in substantially parallel relationship to each other;
- and
- (2) a plurality of warp yarns woven over and under said fill yarns to form a texture having a plurality of plateaus and low points;
- wherein only said plateaus of said warp yarns engage the other of said members , said plurality of fill yarns and said plurality of warp yarns being woven to define a plurality of channels each of which comprise an entry and exit for channeling a cooling medium in a desired flow path.
4 more elements
A friction facing material for use in a clutch or brake environment, comprising:
- (a) a plurality of first yarns;
- and
- (b) a plurality of second yarns woven with said plurality of first yarns to form a plurality of flow paths or channels, each of said plurality of flow paths channels having an entry and an exit to control fluid flow between a low pressure area and a high pressure area.
A product comprising a friction material, said friction material comprising:
- a plurality of fibers formed into strands woven or braided together into a fabric, said strands having a binder so that said fibers are bound together;
- said strands being woven to define a flow path comprising an entry and an exit for oil to inhibit formation of a hydrodynamic film across an engagement surface of the friction material.
