Abstract

A transfer case includes an input shaft, first and second output shafts and a planetary gearset including a ring gear fixed for rotation with the input shaft. A planet carrier is fixed for rotation with the first output shaft. A range clutch is operable in a first range position to drivingly connect the ring gear and the planet carrier as well as in a second range position to restrict the sun gear from rotation to drive the first output shaft at a reduced speed. A mode clutch is operable to connect and disconnect the first output shaft and the second output shaft. A range actuator moves the range clutch between its first and second range positions. A mode actuator moves the mode clutch between its first and second mode positions. A control system controls the range clutch and the mode clutch.
