    摘要: A drive shaft assembly (10) includes an aluminum torque tube (12) and aluminum yokes (14) that are arc welded to the ends of the torque tube. The torque tube has a hollow cylindrical end portion (16) at each end that is pressed onto an annular end portion (20) of the respective yoke to form a narrow annular slit (30, 230). The two parts are then arc welded together by forming an electric arc between the parts at the narrow annular slit and a consumable aluminum based electrode (34). The electric arc is sustained with a pulsed high amperage direct current to fill the narrow annular slit with aluminum based material from the consumable electrode in a single pass.

    摘要: An aluminum driveshaft assembly (10) is dynamically balanced by locating steel plates (14) at desired locations on an exterior surface of an aluminum driveshaft (12), inserting tapered aluminum studs (16) through tapered holes (15) of the aluminum or steel plates (14), and inertia or friction welding (17) the bases of the aluminum studs (16) to the exterior surface of the driveshaft (12) to retain the steel plates (14). Alternatively steel plates (114) with round cylindrical holes (115) are attached to the driveshaft (12) by round cylindrical studs (116). The cylindrical studs (116) are friction welded to the driveshaft (12) after the aluminum or steel plates (14) are located on the driveshaft (12) and steel plates with cylindrical holes (114) are then inserted onto the studs (116). Cylindrical studs (116) may also be friction welded before the aluminum or steel plates (114) are added. In this case aluminum or steel plates (114) are then added and the stud (116) is rolled over in a secondary operation.

    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.
