Abstract: The present invention is directed to a pump arrangement for use in a gear box housing. The interior surface of the gear box housing has a collection wall arranged in the interior surface of the housing. A shaft is rotatably disposed through the gear box housing and has a longitudinal bore extending through the shaft that provides a lubrication delivery arrangement for distributing lubricant through the gear box housing. A pump housing circumscribes the shaft and has a discharge cavity connected to the longitudinal bore. Additionally, the pump housing has an inlet port for receiving lubrication from the collection wall. Contained within the pump housing is a pump member that has an impeller face and helical threaded surface that pressurizes and introduces the lubricant into the lubricant delivery arrangement.

Abstract: A motor vehicle transfer case includes an input shaft and an electromagnetic brake for retarding rotation of the input shaft. An electromagnetic coil is mounted to the front of the transfer case about the input shaft. An armature plate is secured to the input shaft adjacent the electromagnetic coil. Energization of the coil retards rotation of the input shaft and cancels neutral drag torque from the transmission thereby eliminating relative rotation between the shifting elements of the transfer case and providing smoother shifts.
