Abstract
A transfer case (30) and a method of assembly can include a range shifting assembly (60) and a clutch assembly (80) located axially adjacent to one another along a common primary axis. An actuating device (32) can include a concentric gear located coaxially interposed between the range shifting assembly (60) and the clutch assembly (80) for rotation about the common primary axis. The concentric gear (48) can actuate the range shifting assembly (60) during a portion of angular rotation about the common primary axis and can actuate the clutch assembly (80) during a mutually exclusive portion of angular rotation about the common primary axis. The actuating device (32) can include a barrel cam (59), a plurality of springs engageable between the barrel cam (59) and the concentric gear (48), and a shift fork (68) operably engageable with a cam surface groove (57) for guided axial movement to actuate the range shifting assembly (60) between a low-range and high-range drive mode.
