Abstract
The invention seeks to minimize the vibration and noise in a clutch plate system, by damping either or both the clutch plate and pressure plate with the use of various engineered viscoelastic materials. A clutch plate assembly is provided, comprising a plate body having a first surface and a second surface. In a first embodiment of the invention, the plate body is formed from a laminated sheet structure including two layers of steel having a viscoelastic core between the two layers and coextensive with the two layers. The viscoelastic core may be tunable to damp at different temperatures. In a second embodiment of the invention, an engineered viscoelastic material is used as a layer of bonding material for the first and second surface of the plate body. A method for damping a clutch plate assembly is provided.
