  • Vehicle drivetrain component having an internal vent relocation tube for venting a housing of the vehicle drivetrain component
    Patent number: 10054213
    Abstract: A transfer case having a chain drive disposed in a housing. The housing defines a vent aperture and a sump. A lubricating fluid is disposed in the sump and portions of the chain drive travel through the lubricating fluid so that a lubrication surge zone and a splash lubrication zone are formed. The vent aperture is disposed in at least one of the surge zone, the splash lubrication zone and the sump when the transfer case is disposed in at least one orientation in a predetermined range of operating positions in which the transfer case can be operated. A breather relocation conduit is employed to permit air to be vented from the housing to the vent aperture without intaking lubricating fluid into the breather relocation conduit.
