Locking differential assembly

The invention provides a lock-up differential assembly. The lock-up differential assembly includes a differential housing defining an axis of rotation. A lock ring is selectively engageable with the first side gear to selectively prevent rotation of the first side gear and the second side gear relative to the differential housing. A coil is disposed at an end of the differential housing. The armature is selectively geomagnetically actuatable by the coil. An armature position indicator arm is rigidly attached to the armature for simultaneous movement with the armature. At least two relay pin assemblies are each connected to the lock ring and to the armature to space the lock ring from the armature a predetermined distance for translation parallel to the axis of rotation. A sensor is connected to the differential housing to detect proximity of the armature position indicator arm to the sensor and output an electrically detectable signal indicative of an engaged state of the lock ring. 本发明提供了一种锁止式差速器组件，该锁止式差速器组件
