ABSTRACT:
An electric drive unit for a vehicle wheel includes an electric motor that powers a planetary drive having a first stage gear set and a second stage gear set. Each of the first and second stage gear sets includes a sun gear that is driven by a motor output shaft. Each of the first and second stage gear sets also includes a plurality of planet gears that are in meshing engagement with a respective one of the sun gears. The first and second stage gear sets share a common ring gear. A planet carrier of the second stage gear set provides driving output to a wheel shaft that drives the vehicle wheel.
