Abstract
A full-time transfer case is equipped with an integrated planetary gearset assembly and a synchronized range shift mechanism to provide high-range and low-range drive connections. The integrated planetary gearset assembly includes a first gearset which acts as a two-speed reduction unit and second a gearset which acts as an interaxle differential. The synchronized range shift mechanism is arranged to concurrently move two components of the first gearset and is synchronized to permit on-the-move range shifts.
