  • Ancillary oil pumping for gear box assembly
    Patent number: 7963186
    Abstract: A gear box assembly as used in an inverted portal axle or transfer case includes a drive gear and at least one driven gear in meshing engagement with the drive gear at a contact point. A gear housing closely surrounds portions of an outer circumference of the drive and driven gears to form a baffle area. The gear housing includes an discharge orifice that is located near the contact point and a fluid gallery that extends from the discharge orifice to other locations within the gear housing. As the drive gear drives the driven gear, fluid is pumped into the discharge orifice and through the fluid gallery to fluid outlets positioned at desired locations to lubricate other gear box components. Radial inlets with elongated chamfers and stator vanes can be formed within the gear housing to draw air ingested during pumping away from the discharge orifice. Additionally, a bypass loop can be used to scavenge unwanted air ingested into meshing gear teeth.

  • Low floor drive unit assembly for an electrically driven vehicle
    Patent number: 7866423
    Abstract: An automotive vehicle drive unit assembly which is located near the sides of a vehicle includes a first driving axle shaft, a second driving axle shaft, a first gear box, a second gear box, a first electric motor, and a second electric motor. The first driving axle shaft drives a first wheel hub of the vehicle and the second driving axle shaft drives a second wheel hub. Together the first and second driving axle shafts define an axis of rotation about which the first and second wheel hubs rotate. The first gear set drives the first wheel and the second gear set drives the second wheel. A first electric motor is mounted in an angular relationship relative to the axis of rotation and drives the first gear set. A second electric motor is mounted in an angular relationship relative to the axis of rotation and drives the second gear set. A plurality of electric motors can be used to drive each wheel hub.
