Abstract:
A transfer case for use in a vehicle having a power source and first and second drivelines, comprising:an input shaft adapted to receive drive torque from the power source; a first output shaft adapted to transmit drive torque to the first driveline; a second output shaft adapted to transmit drive torque to the second driveline; a planetary gearset having a sun gear driven by said input shaft, a ring gear, and pinion gears rotatably supported from a carrier and which are meshed with said sun gear and said ring gear; a range clutch fixed to said ring gear such that said ring gear translates with said range clutch, said range clutch moveable between first second positions, said range clutch operable in its first position to couple said ring gear to said sun gear for establishing a first speed ratio drive connection between said input shaft and said carrier, and said range clutch is operable in its second position to couple said ring gear to a stationary member for establishing a second speed ratio drive connection between said input shaft and said carrier; an interaxle differential having an input member driven by said carrier, a first output member driving said first output shaft, and a second output member; a transfer assembly interconnected to said second output shaft; a lockout clutch moveable between first and second positions, said lockout clutch is operable in its first position to couple said second output member of said interaxle differential to said transfer assembly and said lockout clutch is operable in its second position to couple said second output member of said interaxle differential to one of said input member of said interaxle differential and said first output shaft; and a shift system for controlling movement of said range clutch and said lockout clutch.
