ABSTRACT:
A torque transmitting device has a plurality of friction discs alternately splined to a housing and a hub. A fluid operated piston is slidably disposed in the housing and is fluid actuated to enforce frictional engagement between the friction discs and establish a torque transmitting interface between the housing and the hub. A one-way device is disposed in the housing at a location axially spaced from the piston. The one-way device has one member splined to the housing and another member splined to the hub. A plurality of actuating elements are disposed between the one-way members to enforce axial separation thereof upon a speed differential between the one-way members in one direction. The axial separation causes engagement of the friction discs to halt the speed differential and provide a one-way torque transmitting apparatus independent of the piston.
