ABSTRACT:
A torsional vibration damping mechanism (30) 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 center portion of 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 center portion. The composite springs include expanded end portions (41a,41b,42a,42b or 106b) to facilitate attachment of end brackets (72) to the springs without need of fasteners penetrating the composite.
