  • Patent number: 10077691
    Abstract: A lubrication and hydraulic actuation system for a transfer case (120) includes a pump (220), a pump sump (210) formed in the transfer case (120), and having an opening (430) in communication with an interior of the transfer case (120), and a fluid retention element (510, 710). The fluid retention element (510, 710) is disposed in the opening (430) of the pump sump (210) and has at least one baffle structure (550) to allow fluids to enter the pump sump (210) through the fluid retention element (510, 710) and restrain fluids from exiting the pump sump (210) through the fluid retention element (510, 710).
    Type: Grant

  • Patent number: 7673539
    Abstract: An arrangement and method for removing a shaft from a gearbox housing without having to totally disassemble the housing. The gear box has an aperture in the housing. The aperture is used to gain access to the retaining ring that locks the shaft within the housing. Once the retaining ring is removed, the shaft may then slide out of the housing. A plug member is used to cover the aperture when it is not necessary to remove the shaft.

  • Patent number: 6230577
    Abstract: Shift control assembly for a power transmission device includes an electric drive motor and gear train having an output which is coupled to and bi-directionally rotates a shift rail. The shift rail includes a pair of spaced-apart cam followers. Freely rotatably receiving the shift rail and disposed thereon between the cam followers is a shift fork assembly. The shift fork assembly includes a body having a pair of spaced-apart helical cam surfaces engaged by the cam followers and a fork engaging a shift clutch collar. As the shift rail rotates bi-directionally, the shift fork assembly and clutch collar bi-directionally translate. A circular plate is disposed for rotation with the shift rail and includes an array of apertures. A plurality of sensors are disposed in adjacent, sensing relationship to the circular plate.
