Limited slip differential using face gears and a pinion housing

A system comprising:

• a pinion housing having:
• a ring including an outer radial surface defined between first and second side surfaces, the ring including a plurality of holes extending through the outer radial surface and a plurality of channels aligned transversely to and extending through the plurality of holes, wherein each of the plurality of holes is configured to support a plurality of radially-extending helical pinions with helical teeth, and each of the plurality of channels is configured such that the helical teeth extend through the plurality of channels to engage helical face side gears;
• and
• one or more transfer formations configured to transfer torque received from a differential case,
• wherein at least one of the one or more transfer formations includes an annular surface that is continuous with and extends radially outwardly from the outer radial surface of the pinion housing;
• at least another one of the one or more transfer formations extends axially from and is substantially parallel to an axial surface of the pinion housing;
• and the at least another one of the one or more transfer formations is curved and disposed radially inward from the outer radial surface of the pinion housing.
