Abstract
A bi-directional overrunning clutch differential is disclosed for controlling torque transmission between a pinion input shaft and at least one output hub in a vehicle. The differential includes clutch a clutch housing and a roll cage. An electromagnetic indexing device is mounted adjacent to the cage and adapted to place the cage in position to engage the output hub to the input shaft. An electrohydraulic device is mounted adjacent to the clutch housing and includes a housing attached to the clutch and adapted to rotate in combination with the clutch housing. A hydraulic piston is located adjacent to a drive plate and adapted to cause the drive plate to engage to the housing when actuated, thereby providing dynamic torque between the output hub and the clutch housing.
