Abstract
A power transmission assembly includes an input member adapted to receive drive torque from a source of torque, an output member adapted to provide drive torque to an output device and a bi-directional roller clutch including a first ring fixed for rotation with one of the input and output members. A second ring is spaced apart from the other of the input and output members. Rollers are positioned in aligned cam tracks formed in facing surfaces of the first and second rings. Neither the first ring nor the second ring support the input member or the output member on the other. The second ring may circumferentially index relative to the first ring for causing the rollers to ride up the cam tracks and force the second ring to frictionally engage the other of the input and output members, thereby establishing a drive connection between the input and output members.
