ABSTRACT:
A differential gear assembly is disclosed. The differential gear assembly includes a first sun gear and a second sun gear coaxially aligned with each other; a first set of planetary gears in mating engagement with the first sun gear; and a second set of planetary gears in mating engagement with the second sun gear. The first and second sets of planetary gears are in mating engagement with each other. The differential gear assembly also includes a first set of friction members, each of which faces a respective one of axial ends of the first set of planetary gears; and a second set of friction members, each of which faces a respective one of axial ends of the second set of planetary gears. The differential gear assembly further includes a first body connecting at least a plurality of said first set of friction members together, and a second body connecting at least a plurality of said first set of friction members together.
