Abstract:
A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.
