ABSTRACT:
A clutch plate for use in friction clutches has an output component in the form of a hub which is connectable to the input shaft of a variable-speed transmission, and an input component in the form of two spaced-apart disc-shaped walls which receive torque from a flywheel when the clutch is engaged. Two dampers are installed between the input and output components, and two diaphragm springs are provided to maintain the members of one damper and the elements of the other damper in proper axial positions relative to each other and relative to the components of the clutch plate. Plastic inserts are used to reduce wear upon metallic parts. One of the dampers is operative alone during a first stage of angular movement of the input and output components relative to each other, and the other damper is operative alone during the next-following stage of such angular movement. Relatively weak energy storing springs operate between the input and output members of the one damper, and stronger or stiffer energy storing springs operate between the input and output elements of the other damper.
