US 2017/0370423 A1 · CLUTCH PLATE HAVING DISCONTINUOUS FRICTION MATERIAL PATTERN

Abstract

The invention comprehends friction plates, typically fabricated of metal, having friction material that is disposed in multiple concentric bands disposed in interrupted or discontinuous segments or a combination of both. In a first embodiment, the friction material is arranged in two concentric bands on each face, an inner band having a smaller radial width and an outer band having a larger radial width. In a second embodiment, the inner band is replaced with a plurality of discontinuous sections or segments wherein their circumferential separation is greater than their circumferential length. A third embodiment is similar to the second embodiment except that the inner, discontinuous segments have a circumferential length greater than their circumferential separation.
