Abstract
A torque transfer assembly includes input and output members configured to transfer torque from a prime mover to an automotive transmission. A torque transfer component, such as a torque converter or a dual-mass fly wheel, and a clutch are coupled to the input member. A torsional vibration damper includes a planetary gear set having first, second, and third nodes. First and second spring engagement elements are connected to two of the first, second, and third nodes. One or more springs contacts both of the first and second spring engagement elements. An outgoing member of the torque multiplying device is coupled to the first node of the planetary gear set, a driven element of the clutch is connected to the second node of the planetary gear set, and the output member is coupled to the third node of the planetary gear set.
