  • Patent number: 10323693
    Abstract: An axle disconnect system for drive axles that utilizes an engagement spring, an electric motor and a slidable gear. The motor is connected to the slidable gear which moves along threads thereby engaging or disengaging clutch teeth on a first side gear which selectively engages a second side gear. The engagement spring is located between a bearing and the first side gear wherein when engagement is desired, but blocked by misalignment of the teeth, the engagement spring can apply a load to allow for engagement once alignment of the teeth is achieved. The use of a second engagement spring allows for the disengagement of the system when disengagement is typically blocked due to high driveline torques without having to reapply current to the motor.

  • Patent number: 9868351
    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.
