ABSTRACT:
A lightweight drive shaft, such as for use as an automotive vehicle engine drive shaft for transmitting engine power, has an elongated extruded tube of uniform external diameter. The tube is formed with a center section and integral opposite end sections which are extruded integrally so as to have similar metallurgical structures. The center section is longer than the end sections. The center section has a thin wall and the end sections each have thick walls of the same thickness, with the thin walls being roughly less than half or about one half the thickness of the thick walls. Also, a coupling formation is formed on the exterior of the thick wall in sections to connect the shaft to a power supply and power take off within a power transmission system.
