Abstract
A power transfer mechanism includes a shift mechanism translating a shift sleeve to a first position where an input shaft is directly drivingly coupled to a first output shaft and to a second position where a reduced speed drive ratio connection exists between the input shaft and the first output shaft as well as the input shaft and a second output shaft via a first planetary gearset. The shift system includes a second planetary gearset having a planet gear fixed for rotation with a lead screw threadingly engaged with the shift sleeve. Rotation of the planet gear axially translates the shift sleeve. A first clamp arm restricts rotation of one member of the second planetary gearset to cause rotation of the planet gear in a first direction. A second clamp arm restricts rotation of another member of the planetary gearset to rotate the planet gear in an opposite direction.
