    Abstract: An axle assembly for frame rail vehicles is described herein. The axle assembly includes a first axle shaft and a second axle shaft orientated along a first axis of rotation. A first electric machine is orientated along a second axis of rotation and a second electric machine is spaced from the first electric machine and orientated along a third axis of rotation. A differential gear set is disposed about the first axis of rotation and is coupled to and driven by a common gear reduction to transfer rotational torque from the first and second electric machines to the first and second axle shafts. A speed change mechanism is coupled between the common gear reduction and the differential gear set to change the rotational torque transferred to the first and second axle shafts.

    Abstract: An axle assembly for a low floor vehicle is described herein. The axle assembly includes an axle housing and a drive unit for driving a wheel assembly. The drive unit includes an axle shaft, a wheel end assembly, an electric machine, and a transmission unit. The axle shaft extends along an axle centerline axis between a first axle end and a second axle end. The wheel end assembly is coupled to the first axle end. The electric machine is positioned within the axle housing and includes a rotor shaft, a drive pinion coupled to the rotor shaft, and an electric motor for rotating the rotor shaft. The rotor shaft extends along a rotor shaft centerline axis that is orientated parallel to the axle centerline axis. The transmission unit is positioned within the axle housing and is configured to transfer torque from the electric machine to the axle shaft.

    Abstract: An axle assembly for frame rail vehicles is described herein. The axle assembly includes a drive unit that includes a first drive unit assembly, a second drive unit assembly, a first axle shaft, and a second axle shaft. The first drive unit assembly includes a first electric machine, a first output assembly, and a first offset gear reduction assembly. The second drive unit assembly includes a second electric machine, a second output assembly, and a second offset gear reduction assembly. The first electric machine and the second electric machine are orientated in a same direction, and spaced such that the axle centerline axis is positioned between the first electric machine and the second electric machine. The first offset gear reduction assembly is spaced from the second offset gear reduction assembly such that the axle centerline axis is positioned between the first offset gear reduction and the second offset gear reduction.
