ABSTRACT:
A shift apparatus for shifting a transfer case between a High-Range operating mode and a Low-Range operating mode. The shift apparatus includes a sector plate supported within the transfer case for rotation about an axis. A range pin member extends into a range slot formed in the sector plate. The range pin member is adapted to move a first shift fork in response to selective rotation of the sector plate between first and second positions corresponding to the High-Range operating mode and the Low-Range operating mode of the transfer case. The range slot has a first camming edge provided for moving the range pin and first shift fork toward the first position upon rotation of the sector plate in a first direction, and a second camming edge for moving the range pin and first shift fork toward the second position in response to rotation of the sector plate in a second direction. According to the present invention, the first and second camming edges are dissimilar for causing different axial force characteristics to be exerted on the range pin member during movement thereof between the first and second positions in response to the direction of rotation of the sector plate.
