PROBLEM TO BE SOLVED: To provide a motor driven transfer case with concentric actuation.SOLUTION: A transfer case 30 and a method of assembly can include a range shifting assembly and a clutch assembly located axially adjacent to each other along a common primary axis. An actuating device can include a concentric gear 48 located coaxially interposed between the range shifting assembly and the clutch assembly for rotation about the common primary axis. The concentric gear 48 can actuate the range shifting assembly during a portion of angular rotation about the common primary axis and can actuate the clutch assembly during a mutually exclusive portion of angular rotation about the common primary axis. The actuating device can include a barrel cam 59, a plurality of springs engageable between the barrel cam 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 between a low-range and high-range drive mode. |
