摘要:
A friction material includes a resin and a fibrous base material impregnated with the resin. The fibrous base material has a single ply, and includes a plurality of aramid fibers present in a first amount, a plurality of polyacrylonitrile-based carbon fibers present in a second amount that is less than the first amount, a plurality of carbon particles present in a third amount that is less than or equal to the second amount, a plurality of mineral fibers present in a fourth amount that is less than or equal to the second amount, and diatomaceous earth present in a fifth amount that is greater than the first amount. A friction member for operatively contacting a lubricated surface includes a substrate and the friction material. The friction material defines a first surface bonded to the substrate and a second surface configured for operatively contacting the lubricated surface.
摘要:
A friction material which includes a porous base material, at least one type of resin material, and at least one type of friction modifying particle is disclosed. The resin material is substantially uniformly dispensed throughout the base material and a layer of a predetermined amount of the friction modifying materials forms a porous top surface on the base material.
摘要:
A friction plate for a clutch assembly includes a core plate and a plurality of friction segments made of a friction material. A plurality of grooves are disposed between said plurality of friction segments. Each segment has tapered sides so that the grooves have a first width adjacent the outer diameter of the core plate and a smaller second width smaller adjacent the inner diameter of the core plate. This tapered groove structure directs oil from the outside the clutch assembly to the inside to improve cooling efficiency.

摘要:
A friction material has a first layer of a base material and a second layer of at least one type of friction modifying particle having substantially symmetrical geometric shapes on a top surface of the base material. The second layer has an average thickness of about 30 to about 200 microns and the surface area coverage of about 80 to about 100% such that the top layer has a fluid permeability lower than the first layer.
