Patent ID: 7033300

Claim:
A transfer case comprising: an input shaft; first and second output shafts; a range unit driven at a reduced speed relative to said input shaft; a range clutch operable in a first range position to establish a drive connection between said input shaft and said first output shaft and further operable in a second range position to establish a drive connection between said range unit and said first output shaft; a mode clutch operable in a first mode position to disengage said second output shaft from driven engagement with said first output shaft and further operable in a second mode position to establish a drive connection between said first output shaft and said second output shaft; a geartrain having an input gear driving an output gear; a motor driving said input gear; a range actuator driven by said output gear for moving said range clutch between its first and second range positions; a mode actuator driven by said output gear for moving said mode clutch between its first and second mode positions; and a control system for actuating said motor to control the magnitude and direction of rotation of said output gear through three distinct ranges of travel so as to coordinate movement of said range clutch and said mode clutch.
