Abstract
An electronic self-locking connect and disconnect system for vehicles. The system includes a motor which turns a gear that meshes with a ring gear contained within a housing. The ring gear meshes with a lead screw thread on an outer surface of a lead screw. When the motor is activated the ring gear rotates the lead screw thread which selectively engages or disengages the clutch. A groove extends on the outer surface of and transverse to the lead screw thread. A pin extends radially inward from an inner surface of the housing till part of the pin is located within the groove. When the pin contacts a radial wall of the groove it prevents further rotation of the lead screw which prevents the stub shaft from axially moving beyond predetermined points. A spring and a sliding collar may be utilized to accommodate full motor travel regardless of the clutch state.
