  • Axle with variable volume sump
    Patent number: 8707826
    Abstract: An axle having a variable volume sump. The axle includes an axle housing that defines a gear chamber and a separate reservoir. The gear chamber and the reservoir are in fluid communication with each other via an opening. A regulator is located adjacent the opening. The regulator is operable to assume a first closed position that obstructs the opening when a temperature in the axle is below a predetermined value, and is also operable to assume a second open position that places the gear chamber and the reservoir in fluid communication via the opening when the temperature is above the predetermined value.

  • Three stages differential assembly and method of operating the same
    Patent number: 7294085
    Abstract: Differential assembly and a method of operating the same. The assembly includes a differential case and a pinion housing including a first pinion gear and a second pinion gear positioned substantially therein. A first side gear and a second side gear are operably coupled to the first pinion gear and the second pinion gear. A sliding collar selectively engages at least one of the differential case, the pinion housing, and the first and second side gears. The sliding collar provides at least three engagement modes. The method includes providing a differential case and a pinion housing including a first pinion gear and a second pinion gear positioned substantially therein. A first side gear and a second side gear are provided. At least one of the differential case, the pinion housing, and the first and second side gears are selectively engaged in one of at least three engagement modes.
