Abstract
A drive assembly, receiving rotational power from an input shaft rotatable about a rotation axis, includes a drive housing and first and second stage planetary gear sets. The first stage planetary gear set includes a first stage sun gear that may be coupled to the input shaft to turn a plurality of first stage planet gears rotatably mounted to a first stage planet carrier that turns with respect to a first stage ring gear, which is fixed with respect to the drive housing. The second stage planetary gear set includes a second stage sun gear turned by the first stage planet carrier to turn a plurality of second stage planet gears rotatably mounted to a second stage planet carrier, which is fixed with respect to the drive housing and about which turns a second stage ring gear. An output hub is rotated about the rotation axis with respect to the drive housing by rotation of the second stage ring gear on the second stage planet carrier.
