Abstract
An axle assembly for frame rail vehicles is described herein. The axle assembly also includes a drive unit housing that includes an interior cavity enclosing first and second electric machines, a common gear reduction, a differential gear set, and a speed change mechanism with the first and second axle shafts partially disposed within the interior cavity and extending out of the drive unit housing. The drive unit housing includes a central cavity, a lower cavity, a first machine cavity, and a second machine cavity. The central cavity includes the common gear reduction and the axis of rotation of the first and second axle shafts. The lower cavity accumulates a volume of gearbox fluid with the speed change mechanism at least partially immersed in the lower cavity. The first machine cavity includes the first electric machine and the second machine cavity includes the second electric machine.
