Formed friction plate for wet friction clutch

摘要

A friction clutch pack exhibiting improved high speed stability includes a first plurality of friction plates or discs preferably having friction material on both faces interleaved with a second plurality of thicker reaction plates or discs. The friction plates comprise a formed core plate having multiple obliquely oriented or angularly offset sinusoidal waves. Male splines around the periphery of each friction plate engage complementary splines on a cylindrical housing. The reaction plates are flat and thicker than the friction plates and include female splines around an inner opening which engage complementary splines on a shaft or quill.

1. A friction clutch pack having reduced spin loss comprising, in combination,
an inner hub having an outer surface defining a plurality of axially extending male splines, an outer member having an inner surface defining a plurality of axially extending female splines, a plurality of reaction plates having a plurality of female splines complementary to and engaged by said plurality of male splines, and a plurality of friction plates having opposed surfaces and including friction material disposed on said surfaces, said plurality of friction plates defining a plurality of sinusoidal waves angularly offset from lines of radius.
