ABSTRACT:
A torque converter turbine, clutch and output shaft are interconnected by a planetary gear arrangement. The gear arrangement combines the output of the turbine and clutch, when engaged, at the torque converter output shaft. The turbine provides a reaction for the gear set so that transient torque spikes, or torsional vibrations, are effectively dampened by permitting the turbine to decrease in speed, and thereby absorb the torque spike energy. A clutch, between the turbine and output shaft, prevents the turbine from overrunning the output shaft when the torque converter clutch is disengaged. The clutch transmits torque from the turbine to the output shaft when the torque converter clutch is disengaged.
