  • Transfer case—method of controlling lubrication—eco— mode operation
    Patent number: 9752671
    Abstract: A transfer case is provided with a primary shaft which is selectively engagable with a secondary shaft via a clutch mechanism. The clutch mechanism is inclusive of a friction pack. A hub of the clutch mechanism is connected on the primary shaft and the clutch housing is torsionally fixed with a primary sprocket rotatively mounted on the primary shaft. A passive or active controlled lubricant collection receptacle is provided which maximize fluid retention in conditions wherein there is not a high demand of torque for the clutch system of the transfer case thereby minimizing fluid that is unnecessarily churned by engagement with the hub connected with the secondary shaft.
    Type: Grant

  • Lubrication in a transfer case without a mechanical pump
    Patent number: 9506504
    Abstract: A transfer case is provided with a primary shaft which is selectively engagable with a secondary shaft via a clutch mechanism. The clutch mechanism is inclusive of a friction pack. A hub of the clutch mechanism is connected on the primary shaft and the clutch housing is torsionally fixed with a primary sprocket rotatively mounted on the primary shaft. A reservoir system is provided for delivering splashed oil axially along the primary shaft overlapping the friction pack. The reservoir system has a collective fluid receptacle that is connected via a stationary passage with a lubrication passage radially inward of the friction pack of the hub.
