Abstract
A shaft connected to a component of a planetary gearset is driveably connected by a coupling to alternate friction elements in accordance with the relative speeds of the coupling members and the direction of rotation of the driven coupling member. The coupling includes a radially inner one-way coupling and an outer one-way coupling, the outer race of the inner coupling and inner race of the outer coupling being the intermediate race, which is connected to the gearset. The inner race and outer race have cam surfaces contacting roller clutch elements located in a cage and spaced mutually about the coupling axis. The cam surfaces of the races are inclined with respect to the adjacent surface of the intermediate race in opposite directions, so that when one coupling drives, the other coupling overruns.
