ABSTRACT:
A clutch assembly includes a hub with a hub friction surface and an inner surface that cooperate to define a cavity. A damper member is situated within the cavity and is in contact with the hub friction surface. The damper member is rotatable with respect to the hub so that relative movement between the damper ring and the hub friction surface results in energy absorption and dissipation to minimize unwanted clutch vibration. The damper ring is located inside the clutch hub so that it does not adversely affect transmission packaging. The clutch assembly preferably includes a member configured to direct lubricant along an inner diameter of the damper member so that it subsequently flows between the damper ring and the hub friction surface and through holes in the hub to lubricate clutch plates.
