Abstract:
A multi-speed clutch-damper assembly for selectively connecting an output of a power-source to an input of a transmission includes a planetary gear-set. The planetary gear-set is encased in a housing and configured to provide two selectable speed ratios and a damper between the power-source output and the transmission input. The planetary gear-set includes first, second, and third gear members. The second gear member is configured to be connected to the transmission input and the third gear member is configured to be selectively fixed to the housing. The planetary gear-set also includes an elastic element operatively connected to the second gear member and configured to generate torsional vibration damping between the output of the power-source and the input of the transmission. The clutch-damper assembly also includes a first clutch configured to selectively connect the power-source output to the first gear member for transmitting torque of the power-source to the transmission.
