  • METHOD AND DEVICE FOR ASSEMBLING SHAFT TO VEHICLE COMPONENT
    Publication number: 20200408296
    Abstract: A vehicle component including a casing and a cap. The casing defines an opening. The cap is removably coupled to the casing such that the cap plugs the opening. The cap including a membrane portion and a rim portion extending around the membrane portion. The cap is configured to be removed from the casing after a shaft is inserted through the membrane portion and at least partially through the opening.

  • Active torque biasing differential using a variable viscosity fluid
    Patent number: 7575531
    Abstract: An active torque biasing differential includes a housing and an outer annulus disposed within the housing. An inner annulus is contained within the outer annulus. The inner annulus includes a plurality of slots. A plurality of vanes are disposed in the slots in the inner annulus. The vanes slidably contact the outer annulus. The vanes include a plurality of orifices formed therein. An electromagnetic coil is placed to apply a magnetic field to a chamber bounded by the outer annulus and inner annulus.

  • 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.
