Axle assembly with torque distribution drive mechanism

摘要

An axle assembly with a motor, a differential assembly, a housing, a transmission and a reduction gearset. The transmission has a first and second planetary gearsets that have associated (i.e., first and second) ring gears, planet carriers and sun gears. The first planet carrier is coupled to a differential carrier of the differential assembly for common rotation. The second ring gear is non-rotatably coupled to the housing. The second planet carrier is coupled to the second differential output for common rotation. The second sun gear is coupled to the first sun gear for common rotation. The reduction gearset is disposed between an output shaft of the motor and the first ring gear and includes a first gear, which is coupled to the output shaft for rotation therewith, and a second gear that is coupled to the first ring gear for rotation therewith.

1. An axle assembly comprising:
a motor having an output shaft disposed along an output shaft axis; a differential assembly having a differential carrier and first and second differential outputs received in the differential carrier, the first and second differential outputs being rotatable about an output axis and being capable of rotating relative to the differential carrier; a housing; a transmission received in the housing, the transmission having first and second planetary gearsets, the first planetary gearset having a first ring gear, a first planet carrier and a first sun gear, the first planet carrier being coupled to the differential carrier for common rotation, the second planetary gearset having a second ring gear, a second planet carrier and a second sun gear, the second ring gear being non-rotatably coupled to the housing, the second planet carrier being coupled to the second differential output for common rotation, the second sun gear being coupled to the first sun gear for common rotation; and a reduction gearset disposed between the output shaft and the first ring gear, the reduction gearset having a first gear, which is coupled to the output shaft for rotation therewith, and a second gear that is coupled to the first ring gear for rotation therewith.
