Abstract:
1. A drive module comprising: a transmission having a transmission housing, a first planetary gearset and a second planetary gearset, the first planetary transmission having a first ring gear and a first transmission output member, the second planetary transmission having a second ring gear and a second transmission output member; a differential assembly having a differential case that is rotatably coupled to the second transmission output member, the differential assembly having a first differential output and a second differential output; a first shaft coupled for rotation to both the first differential output and the first transmission output member; a second shaft coupled to the second differential output for rotation therewith; wherein the first ring gear is rotatably mounted in the transmission housing, wherein the second ring gear is non-rotatably mounted in the transmission housing, wherein the first and second ring gears nest such that one of the first and second ring gears has a bearing hub that is received into a bushing bore that is formed into the other one of the first and second ring gears, and wherein the bearing hub frictionally engages an inside surface of the bushing bore when the bearing hub is received into the bushing bore to thereby align a central axis of the first ring gear to a central axis of the second ring gear.
