Abstract
A clutch disc assembly for a friction torque device has a clutch damper assembly which includes a hub defining an axis of rotation and a concentric steel disc. The damper assembly includes a plurality of cushion elements fixed to the steel disc. First and second friction rings are disposed on opposite sides of the cushion elements and are rotatively fixed to the steel disc. First and second friction discs have an equal number of keyhole slots defining an equal number of arms. A friction pad is fixed to each arm, with friction pads on the first friction disc being in substantial alignment with the friction pads on the second friction disc.
