Patent attributes
An electronically triggered locking differential includes a differential case, at least one pinion gear and a pair of side gears. A clutch pack is disposed between one of the side gears and the differential case and retards relative rotation between the differential case and the side gear. A cam member is disposed adjacent the clutch pack so that the clutch pack engages when the cam member ramps up. An engagement shaft has one end engaged with the cam member and an opposite end extending through the differential case and engaged with a sprocket. A magnetic coil and flux conductor magnetically couple the sprocket to the differential case when the coil is energized. This coupling retards rotation of the engagement shaft and the cam member relative to the gear case, initiating engagement of the clutch pack to lock the differential.
