A transfer case is provided with a range unit, an interaxle differential, a clutch
assembly and a power-operated actuation mechanism. The range unit includes a planetary
gearset driven by an input shaft, and a synchronized dog clutch assembly for releasably
coupling one of the input shaft or an output component of the planetary gearset
to an input member of the interaxle differential. The interaxle differential further
includes a first output member driving a first output shaft, a second output member
operably driving a second output shaft. The clutch assembly is a multi-plate friction
clutch operably disposed between the first and second output shafts. The power-operated
actuation mechanism includes a range actuator assembly, a ball-ramp clutch actuator
assembly and a motor assembly operable to control actuation of the range actuator
assembly and the clutch actuator assembly.
