A bi-directional overrunning clutch assembly ( 10, 110, 210 ) including a drive member ( 12, 112, 212 ) that is rotatable about an axis (A) and a pair of driven members ( 14, 16; 114, 116; 214, 216 ) that are similarly rotatable about the axis of rotation. and are disposed on either side of the drive member ( 12, 112, 212 ). A first engagement mechanism ( 26, 126, 226 ) is supported between the confronting surfaces of the drive member ( 12, 112, 212 ) and one of the driven members ( 14, 114, 214 ). A second engagement mechanism ( 28, 128, 228 ) is supported between the confronting surfaces of the drive member ( 12, 112, 212 ) and the other driven member ( 16, 116, 216 ). A pair of actuators ( 32, 34; 132, 134; 232; 234 ) are associated with the first and second engagement mechanisms ( 26, 28; 126, 128; 226, 228 ). Each actuator is operable to move its associated engagement mechanism in an axial direction between the disengaged and engaged positions.
