Abstract: An electronically locking differential assembly constructed in accordance to the present disclosure includes a differential casing, a first and second side gear, a lock actuation assembly and a lock detect mechanism. The first gear defines a first shaft opening configured to provide a first torque transmitting connection with a first output shaft received within the first output shaft opening. The second side gear defines a second output shaft opening configured to provide a second torque transmitting connection with a second output shaft received within the second output shaft opening. The lock actuation mechanism selectively moves between a locked state where the side gears are fixed for concurrent rotation and an unlocked state where the side gears rotate relative to each other. The lock detect mechanism detects whether the lock actuation mechanism is in the locked or unlocked state.

Abstract: A locking differential assembly includes a differential case defining an axis of rotation and a gear chamber. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case opposite the first end for selectable rotation relative to the differential case. At least two pinion gears are rotatably supported in the gear chamber in meshing engagement with the first side gear and the second side gear. A solenoid is at the first end. A plunger is selectably magnetically actuatable by the solenoid. A lock ring is selectably engagable with the second side gear to selectably prevent the side gear from rotating relative to the differential case. At least two relay rods are each connected to the plunger and to the lock ring to cause the lock ring to remain a fixed predetermined distance from the plunger.

Abstract: A locking differential assembly includes a differential case defining an axis of rotation. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case. A stator is disposed at the first end. A solenoid is fixedly attached to the stator. The stator is selectably magnetically actuatable to translate an axial translation distance by the solenoid. A lock ring is selectably engagable with the first side gear to prevent the first side gear from rotating relative to the differential case. At least two relay pins are connected to the lock ring and in contact with the stator to space the lock ring at least a predetermined distance from the stator.
