Abstract
A bi-directional overrunning clutch differential for controlling torque transmission between a pinion input shaft and at least one output hub. The clutch having a clutch housing and the roll cage mounted within the housing. An engagement control assembly is provided for controlling the relative position of the roll cage with respect to a cam surface on the clutch housing. The engagement control assembly includes an electronically controlled actuation device, such as a coil or solenoid, which when activated causes the roll cage to rotate into a second position relative to the clutch housing to engage the rolls with the cam surface and an outer surface of the hub. A spring is engaged with the clutch housing and has an end engaged with the roll cage for biasing the roll cage into a neutral position when the roll cage is in its second position.
