Abstract
A multi-directional planetary transmission mechanism adapted to establish plural torque flow paths between a driving member and a driven member including a one-way torque delivery clutch located in the torque flow path from the torque input element of the planetary gear system and a torque output shaft, and a friction brake means for anchoring the torque input element of the planetary gearing to establish a change in torque ratio wherein provision is made for disengaging the one-way clutch to interrupt torque delivery therethrough in either a driving direction or a coast direction and simultaneously anchoring said torque input element of said gearing to provide a torque reaction point.
