Abstract
A vehicle drive system capable of selectively providing all-wheel drive and single-driven-axle modes includes a front drive unit having a planetary gearset with a grounded ring gear and a sun gear driven by the transaxle's drive spool via an input shaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby selectively provide both an available low range and a front axle disconnect. The front drive unit further defines a power take-off unit with a clutch selectively coupling the input shaft to a propshaft. The rear drive unit includes a planetary gearset with a grounded ring gear, a sun gear driven by the propshaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby likewise selectively provide both an available low range and a rear axle disconnect.
