Abstract
An electric drive system in a battery electric vehicle (BEV) includes 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; and a housing that receives the differential having an outer surface that is configured to couple to a rotating electrical machine of the BEV, wherein the pinion gears engage the face gear and permit angular displacement of the output shaft relative to another output shaft.

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;
- and
- a housing that receives the differential having an outer surface that is configured to couple to a rotating electrical machine of the BEV, wherein the pinion gears engage the face gear and permit angular displacement of the output shaft relative to a second 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.
