Abstract:
A drive module that includes a Ravigneaux gearset, a first input shaft, first through fourth gears, and a differential assembly. The Ravigneaux gearset has a carrier, a first sun gear, a second sun gear, and a plurality of first planet gears that are journally supported by the carrier and drivingly coupled to the first and second sun gears. The first input shaft is coupled to the first sun gear for rotation therewith. The first gear is coupled to the first input shaft. The second gear is meshingly engaged to the first gear. The differential assembly has a differential input and first and second differential outputs. The differential input is coupled to the second gear for rotation therewith. The third gear is coupled to the carrier for rotation therewith. The fourth gear is coupled to the first differential output for rotation therewith and is meshingly engaged to the third gear.
