  • Patent number: 6691830
    Abstract: A device for lubricating a power gearbox having a variable orientation and a closed space has a lubricating unit that supplies lubricant to at least one element of the gearbox, which needs to be lubricated. A collecting reservoir collects lubricant from the closed space. A drain screw chamber, within the closed space, has a number of orifices disposed between different zones of the closed space and the drain screw chamber for passing lubricant there between. At least one rotary drain screw, which is produced in the form of an Archimedean screw, is disposed in the drain screw chamber to convey the lubricant from the drain screw chamber to the collecting reservoir. A drive unit drives the drain screw in rotation for conveying the lubricant. The orifices open respectively different zones of the closed space to the drain screw chamber such that the drain screw chamber can always collect lubricant from the different zones regardless of the orientation of the gearbox.

  • Patent number: 6622583
    Abstract: A shifter system includes an automatic transmission shifter lever movable along a first shift path in forward and rearward directions and a transfer case shifter lever movable along a second shift path in the forward and rearward directions. The automatic transmission shifter lever is also movable in lateral directions to provide an auto stick option. The second shift path is laterally adjacent the first shift path a short distance to reduce space. An interlock mechanism is provided to prevent contact between the shifter levers. The interlock mechanism includes a blocker pivotable between a locking position wherein the blocker limits movement of the transfer case shifter lever along the second shift path and an unlocking position wherein the blocker does not limit movement of the transfer case shifter lever along the second shift path.
