Abstract
One implementation of a vehicle power transfer unit (PTU) assembly—such as thatfor an automobile—includes an input shaft, a planetary gear set, an intermediate shaft, a ring gear, and an output gear. The planetary gear set includes a sun gear, multiple planet gears, and an annular gear. The sun gear is attached to a housing of the vehicle PTU and does not rotate in use. The planet gears are interconnected to the input shaft and are driven by the input shaft. The annular gear is in turn driven by the planet gears. The intermediate shaft is interconnected to and driven by the annular gear. The ring gear is interconnected to the intermediate shaft, and the output gear is driven by the ring gear.
