ABSTRACT:
A torsional vibration damping mechanism (30) is disclosed in a free standing clutch plate (26) for a vehicle driveline. The mechanism (30) includes composite C-shaped springs (41,42) for attenuating driveline torsionals and transmitting driveline torque, and a viscous damper (48) for controlling the rate of flexing of the springs. The mechanism also includes input and output drives (46,44) for flexing the springs only radially inward. The C-shaped composite springs are formed by removing a minor arc of a closed ring comprising a plurality of layers of reinforcing filaments, or by cutting a composite cylinder into closed rings and removing the minor arc.
