摘要： An electric drive unit (10) for a vehicle wheel (12) includes an electric motor (14) that powers a planetary drive (16) having a first stage gear set (40) and a second stage gear set (42). Each of the first and second stage gear sets includes a sun gear (44) that is driven by a motor output shaft (18). Each of the first and second stage gear sets also includes a plurality of planet gears (46) 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 (54). A planet carrier (62) of the second stage gear set provides driving output to a wheel shaft (22) that drives the vehicle wheel (12).
