A full-time two-speed transfer case (20) is equipped with an integrated planetary gearset assembly (42) and a range shift mechanism (44) to provide high-range and low-range drive connections. The integrated planetary gearset assembly (20) includes a first gearset (48) which acts as a two-speed reduction unit and second gearset (50) which acts as an interaxle differential. The synchronized range shift mechanism (44) is arranged to concurrently move two components (68,70) of the first gearset (48) and can be synchronized to permit on-the-move range shifts.
L'invention concerne une boîte de transfert à deux rapports en prise permanente comprenant un ensemble train planétaire intégré et un mécanisme de changement de gamme assurant des liaisons d'entraînement à gamme haute et à gamme basse. Cet ensemble train planétaire intégré comprend un premier train agissant comme une unité de réduction à deux rapports et un second train agissant comme un différentiel inter-ponts. Le mécanisme de changement de gamme synchronisé est conçu pour déplacer simultanément deux composants du premier train, et peut être synchronisé de façon à permettre des changements de gamme en cours de déplacement.
