摘要： Methods for making an aluminum drive shaft for automobiles or trucks or other drive shaft applications from aluminum alloy tube and methods for making said tube including using an aluminum alloy containing about 0.5 to 1.3% magnesium, about 0.4 to 1.2% silicon, and about 0.6 to 1.2% copper and preferred practices for making the tube. The preferred practices include extrusion temperature and other aspects of extrusion, along with cold drawing. One preferred practice includes reducing tube diameter and increasing wall thickness at one or both ends of the drive shaft tube shortly after solution heating and quenching and applies to various 6000 Series type aluminum alloys.

摘要： Methods for making an aluminum drive shaft for automobiles or trucks or other drive shaft applications from aluminum alloy tube and methods for making drive shafts. The method includes (a) providing an 6000 series type alloy hollow elongate tube; and (b) reducing the diameter of at least one portion of the hollow elongate tube to form a reduced diameter section and transition section between the reduced diameter section and the tube; the transition section having at least three subsections: i. a first subsection having a first slope; ii. a second subsection having a second slope; and iii. a third subsection located between the first and second subsections having a third slope which is less than the first and second slopes, the third section forming a circumferential step to stiffen the transition section. The drive shafts can also be made of metals other than aluminum alloys.

摘要： Methods for making an aluminum drive shaft for automobiles or trucks or other drive shaft applications from aluminum alloy tube and methods for making drive shafts. The method includes providing an aluminum tube member is joined to drive shaft end members. The method includes the steps of (a) providing a 6000 series type alloy; (b) extruding the alloy within about 500.degree. to 800.degree. F. into a hollow elongate tube; (c) drawing the tube to a reduction of at least 15% in metal cross-sectional area; (d) solution heat treating the alloy at a temperature of at least about 990.degree. F. and then quenching; and (e) reducing the diameter of the tube and increasing the tube wall thickness to provide a relatively short tube length of reduced diameter, a transition section and thicker wall thickness at one or both ends of a drive shaft suitable length of said tube. The transition section has a non-linear wall. In a preferred embodiment, the transition section has central circumferential stiffener section. In a more preferred embodiment the central circumferential stiffener section has a slope of from 0.degree. to 5.degree.. The circumferential steps stiffen the transition section and prevents "oil canning" of the drive shaft under periods of high torque. The drive shafts can also be made of metals other than aluminum alloys.
