Abstract

See full text

An output transfer group, or drop box, can include a housing and a gear transfer train, rotatably supported within the housing, that includes an input gear adapted for enmeshing engagement with a transmission output shaft and a gear transfer output shaft that is rotatable upon rotation of the input gear. A coupler can be provided that includes a hub rotatively coupled with the gear transfer output shaft, a bearing carrier, a coupler output shaft rotatively coupled to the bearing carrier, and a coupling mechanism rotatively coupled to the bearing carrier. The coupling mechanism can be movable between an engaged position, wherein the coupling mechanism is rotatively coupled to the hub, and a disengaged position, wherein the coupling mechanism is disengaged from the hub. A solenoid can be arranged with the coupling mechanism to selectively move the coupling mechanism from the disengaged position to the engaged position.
