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