  • Modular split shaft transfer case
    Patent number: 8069741
    Abstract: A split shaft transfer case includes a first housing portion and a second housing portion that are secured together along a plane of engagement to form an enclosure. An input shaft and an output shaft that are each supported for rotation about an axis of rotation that is generally parallel to the plane of engagement defined by the first and second housing portions. A first operating shaft is supported for rotation about an axis of rotation, and a first operating clutch selectively connects the first operating shaft to the input shaft for rotation therewith. A second operating shaft supported for rotation about an axis of rotation, and a second operating clutch selectively connects the second operating shaft to the input shaft for rotation therewith. The axis of rotation of at least one of the first and second operating shafts is movable relative to the axis of rotation of the input and output shafts.
