Abstract
The multiplate clutch for an automatic transmission includes a composite separator plate that reduces chatter and the frequency of vibrations transmitted through the separator plate. The separator plate includes a first rigid steel member, a second rigid steel member, and a layer of a viscoelastic material bonded between the two rigid members. The separator plate has projections extending from the first and second rigid members and the viscoelastic layer to engage a rotating drum or a splined shaft. Each of the rigid members has a thickness of between 0.010 to 0.090 inches, and the viscoelastic layer has a thickness of between 0.001 to 0.005 inches.
