  • Patent number: 8783393
    Abstract: The present invention provides an interface for aligning a power-producing device and a power-transferring device in a vehicle. The interface includes an axle tube housing and a flange integrally coupled at one end of the axle tube housing. The flange has a rear surface. The interface also includes a motor housing and a drive housing. The motor housing is configured to contain the power-producing device and the drive housing is configured to contain the power-transferring device. A plate is removably coupled to one end of the motor housing. The plate is coupled to the axle tube housing and has an outer diameter. The interface further includes a spindle coupled to the drive housing. The spindle has a front surface and an inner diameter. The outer diameter of the plate contacts the inner diameter of the spindle when the spindle is coupled to the flange.

  • 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.
