    摘要： A method that includes: providing a blank; heating the blank; forging the heated blank to form a forged gear having a plurality of spiral bevel gear teeth; machining the forged gear to a predetermined thickness while locating off of the plurality of gear teeth to form a green machined forged gear; rotationally and axially engaging a die to the gear teeth of the green machined forged gear to induce plastic flow in the gear teeth to form an intermediate gear in which the plurality of gear teeth conform to a predetermined tooth form; heat-treating the intermediate gear to form a hardened intermediate gear; and lapping the plurality of gear teeth of the hardened intermediate gear with a spiral bevel pinion gear; wherein the plurality of gear teeth are not machined in a chip-producing machining operation before the plurality of gear teeth are lapped.

    摘要： A method is used to manufacture a drawn tube having a hollow low interior for housing an axle shaft. The method includes the steps of placing a billet into a first die assembly and pressing the billet into the first die to producing a pre-formed billet. The method also includes the steps of moving the pre-formed billet from the first die assembly to a second die assembly and pressing the pre-formed billet into the second die assembly to produce an extruded tube. The method further includes the steps of moving the extruded tube from the second die assembly to a third die assembly and pressing the extruded tube into the third die assembly to further elongate the extruded tube and decrease the thickness of the wall of the extruded tube to of from about 3 to about 18 millimeters to produce the drawn tube having the yield strength of at least 750 MPa.

    摘要： A differential assembly (26) for a vehicle includes a differential casing (40) rotatable about an axis. A pair of side gears (68a,68b) are disposed within the differential casing (40). A first, second, third and fourth pair of pinion bores are formed in the differential casing. A first, second, third and fourth pair of pinion gears (100a,100b,102a,102b,104a,104b,106a,106b) are slidably and rotatably disposed in the first, second, third and fourth pair of pinion bores (110a,110b,112a,112b,114a,114b,116a,116b) respectively. A window opening (124) is formed in the differential casing (40) between the first (100) and fourth pair (106) of pinion gears. The second pair of pinion bores (112) are radially offset an equivalent distance from the first (110) and third pair (114) of pinion bores. The third pair (114) of pinion bores are radially offset an equivalent distance from the second (112) and the fourth pair (116) of pinion bores. The differential assembly (26) incorporates a cross pin adapted to limit inward movement of a pair of axle shafts and a spacer adapted to limit inward movement of the side gears.

    摘要： A method for forming a stepped shaft includes: forming a billet of a predetermined mass; heating the billet; cross-wedge rolling the billet to form an intermediate workpiece having a first cylindrical portion and a second cylindrical portion that are axially spaced apart by a neck that is smaller in diameter than the first and second cylindrical portions; and performing at least one upset forging operation on the end of the intermediate workpiece to enlarge the first cylindrical portion such that in at least one location its diameter is larger than a diameter of any other portion of the stepped shaft and larger than a diameter of the billet.

    摘要： A wheel speed measurement system for a drive axle is provided within a differential assembly. The system includes a differential side bearing adjustment ring (96) configured for adjusting the position of a differential carrier bearing assembly (98). A tone ring (82) is provided having an inner bore to accommodate a coaxial axle shaft. A retainer ring member (94) is snap-fit between the differential side bearing adjustment ring (96) and the tone ring (82), permitting relative rotation of the tone ring (82). Sensors (76) are provided in sensor mounts integrally formed on an exterior of a differential assembly housing (32).

    摘要： A power transmission device includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft. A carrier is fixed for rotation with the output shaft. A pump assembly includes an inner rotor supported for rotation on the carrier and an outer rotor encompassing the inner rotor. The outer rotor is in driving meshed engagement with the ring gear. The pump provides pressurized fluid to one of first and second fluid ports. A flow restrictor is moveable to selectively restrict fluid flow relative to one of the first and second ports.
