  • Differential gear assembly
    Patent number: 8287418
    Abstract: A differential gear assembly is disclosed. In some embodiments, 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 can be in mating engagement with each other. In some embodiments, 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.
