Claim Text:
1. A vehicle axle electromagnetic disconnect system, comprising: an output housing having an armature with a coil and an output shaft bearing, the coil and the output shaft bearing fixedly attached to the output housing; an output shaft having splines and angled cams disposed on an end thereof; a pressure plate in contact with the armature; a sliding dog clutch having angled cams, slidably attached to the output shaft angled cams, and the output shaft axially disposed through an opening in the output housing and in rotational contact with the output shaft bearing; an input housing fixedly attached to the output housing, the input housing having an input shaft bearing fixedly attached thereto; a disengagement spring; and an axially fixed dog clutch rigidly attached to an end of an input shaft that is axially disposed through an opening in the input housing and in rotational contact with the input shaft bearing; wherein, the coil is energized with rotational torque from the input shaft to the output shaft present, the output shaft cams are unseated within the sliding dog angled cams by the armature and the pressure plate, thus the sliding dog clutch is in slidable mechanical engagement with the axially fixed dog clutch and the output shaft cams self-lock a transfer of the input shaft rotational torque to the output shaft; and wherein, the coil is de-energized to seat the sliding dog angled cams within the output shaft angled cams, to disengage the armature and the pressure plate by way of the disengagement spring, and no longer transfer rotational torque from the input shaft to the output shaft.
