  • Patent number: 8727052
    Abstract: An axle tube comprising a dry section interposing a first wet section and a second wet section, the first and second wet sections housing a liquid lubricant, the dry section having an interior isolated from the liquid lubricant, at least one of the first and second wet sections includes a power train, and at least one of the first and second wet sections includes an electric motor, wherein the electric motor is at least partially received within the dry section, wherein a fluidic seal interposes the electric motor and the dry section, and wherein the electric motor is not rigidly mounted to the dry section.
    Type: Grant
    Filed: February 24, 2011
    Date of Patent: May 20, 2014

  • Patent number: 8485289
    Abstract: A method and associated apparatus for controlling fluid levels within an axle tube, the method comprising: (a) establishing a first predetermined level of a liquid lubricant within a transmission and an electric motor operatively coupled to the electric motor, the axle tube housing the electric motor and the transmission, where a cavity interposing a wall of the axle tube and the electric motor is occupied by the liquid lubricant reservoir at a second predetermined level; and, (b) lowering the first predetermined level of a liquid lubricant within the electric motor and the transmission by changing a gas pressure exerted upon the liquid lubricant, where changing the gas pressure exerted upon the liquid lubricant within the axle tube raises the second predetermined level of liquid lubricant within the cavity.
