Abstract: A transfer case for a vehicle is provided having a normal two wheel drive mode and a selective four wheel drive mode. The transfer case has a common motor for range shifting and clutch actuation and further has an anti-neutral drive biasing device preventing the range shifting assembly from dropping out of high or low gear to a neutral mode inadvertently.

Abstract: A product may include a case, and a shaft that rotates may extend into the case. A bearing may support the shaft at the case. A seal may be positioned around the shaft outboard from the bearing. The bearing may have a first side facing the seal and a second side facing away from the seal. The case may define an inlet to an area between the bearing and the seal. A baffle may extend over the inlet on the second side and radially outside the bearing.

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).

Abstract: A transfer case (16) for translating torque from an engine (12) to first and second differentials (20, 22), including: a housing (42), a primary shaft (44) supported in the housing (42) with an input end (52) in communication with the engine (12) and an output end (54) in communication with the first differential (20), a secondary shaft (46) spaced from the primary shaft (44) and in communication with the second differential (22), a clutch assembly (48) in communication with the shafts (44, 46) for selectively translating torque therebetween, and a sleeve (50) operatively attached to the primary shaft (44) between ends (52, 54). The sleeve (50) has an outer surface (68) with a plurality of radially spaced flutes (70) defined therein for directing lubricant from a predetermined location (72) of the housing (42) toward the clutch assembly (48) during rotation of the primary shaft (44).

Abstract: A vehicle transfer case is provided including input and output shafts mounted within a housing, a secondary shaft selectively driven by the output shaft, a first hub having an inner diameter splined section having a first extreme neutral position with exclusive torsional engagement with the output shaft, and in a second intermediate high position having torsional engagement with the output shaft and input shafts, and in a third extreme low position having exclusive torsional engagement with the input shaft. A second hub is provided, rotatably mounted on the first hub and axially fixed therewith. The second hub is torsionally fixed to the output shaft, and a shift fork is provided to translate the second hub.
