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.

Nonsynchronous five-speed transaxle having bidirectional coupling

A hydrokinetic multiple ratio transmission having a compound planetary gearset with clutches and brakes that are selectively engageable and released to establish two underdrive ratios, a direct drive ratio and an overdrive ratio, as well as a reverse ratio, the clutches and brakes being operable by fluid pressure operated servos, the clutches and brakes for establishing the underdrive ratios and the direct drive ratios being disposed between the planetary gearing and a hydrokinetic torque converter, a friction clutch engageable for overdrive operation and disposed on the opposite side of the planetary gearing and two torque input shafts, one being concentrically disposed with respect to the other, the torque input shaft for overdrive operation being connected to torque input portion of the overdrive clutch through an intermediate shaft adapted for articulation to accommodate eccentricities between the bearing supports disposed on opposite sides of the planetary gearing.
