Abstract:
An actuator for a transfer case includes an actuator member, a face cam mechanism, and a motor. The actuator member includes a circumferential flange and an annular body extending from an inner periphery of the circumferential flange. The annular body includes a circumferential slot opposite the flange defined between two end walls formed by the annular body. One of the end walls includes a bearing member coupled thereto. The face cam mechanism includes a follower coupled to a cam member. The cam member is configured to displace axially when rotated. The follower is disposed within the slot. In a first range of motion, the annular member is rotated independent of the face cam mechanism. In a second range of motion, the bearing member engages the follower to rotate the second cam member relative to the first cam member, and the follower moves axially along the bearing member.
