Differentials with face gears for electrical drive systems

An electric drive system in a battery electric vehicle (BEV), comprising:

• an output shaft, configured to couple with a drive wheel of the BEV, having a face gear at a distal end;
• a differential, including a pinion gear cage receiving pinion gears rotatably connected to the pinion gear cage via gear pins, having radially-outwardly-facing gear teeth that are oriented at a non-zero angle relative to an axis of rotation;
• a housing receiving the differential that is configured to couple to a rotating electrical machine of the BEV, and engages the radially-outwardly-facing gear teeth preventing radial and axial movement of the differential relative to the housing;
• and
• one or more reduction gearboxes coupled to the output shaft and configured to couple to the drive wheel of the BEV, wherein the pinion gears engage the face gear and permit angular displacement of the output shaft relative to another output shaft;
• wherein the pinion gear cage includes a central hub, spokes, pinion gear slots and apertures on an outer surface of the pinion gear cage that receive the gear pins and rotatable secure the pinion gears relative to the pinion gear cage.
