摘要： A hypoid gear set for a vehicle drivetrain includes a pinion gear in meshing engagement with a ring gear. The hypoid gear set has a negative pinion offset. The hypoid pinion and ring gears provide a predetermined gear ratio that can be varied up to a fifty percent faster ratio within a single carrier packaging envelope defined by a maximum ring gear diameter.

摘要： 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.

摘要： A drive axle assembly is provided that includes an axle housing having a cavity. A differential case is disposed within the cavity. The ring gear is supported on the differential case such as by fastening the ring gear to a flange extending from the differential case. A pinion cage eccentrically supports the driveshaft and pinion, which are rotatable about a first axis. The pinion cage may be used for different axle assemblies having different gear ratios. Moreover, the same differential case may be used for the different axle assemblies. The pinion cage is rotatable relative to the carrier housing between first and second positions in which the first axis is spaced from the ring gear first and second distances, respectively. In this manner, the pinion offset and gear mounting distance may be varied. The pinion cage is secured to the housing, preferably by fasteners, in one of the positions to accommodate a particular gearset.
