Articulated shaft for automotive vehicles and method of producing an articulated shaft

摘要

The vehicle propeller shaft is a tube with a longitudinal welded seam, of an aluminum alloy without additives. The aluminum alloy is hardened, using AlMgSi, with a tube wall thickness of≥1 mm. Before welding, the aluminum alloy is given a solution annealing followed by quenching followed by a heated dwell time. The tube has a heated dwell time after welding. The seam is welded by high frequency induction (HFI) welding, with the raised welded seam height within a tolerance of 0.2 mm.
