Abstract:
A transfer case comprising:an input shaft; first and second output shafts; a planetary gearset including a sun gear fixed to said input shaft, a ring gear, and a set of pinion gears meshed with said ring gear and said sun gear and which are rotatably supported from a carrier; a range sleeve fixed to said ring gear and moveable between first and second positions, said range sleeve is operable in its first position to couple said ring gear to said sun gear and is operable in its second position to couple said ring gear to a stationary member; an interaxle differential driven by said carrier and having a first output operably fixed for rotation to said first output shaft, a second output operably fixed for rotation with said second output shaft, and a gearset for transferring drive torque from said carrier to said first and second outputs while permitting speed differentiation therebetween; and an actuator for controlling movement of said range sleeve.
