Abstract
An on-demand two-speed transfer case is equipped with a planetary gearset and a range shift mechanism to provide high-range and low-range drive connections. The range shift mechanism is arranged to concurrently move two components of the planetary gearset and can be synchronized to permit on-the-move range shifts.
