Method of manufacturing a transverse support as a component of a twist beam axle

摘要

A transverse support as a component of a twist beam axle of a passenger car has a bending resistant, torsionally yielding tubular profiled member formed by cold-forming a tube blank of a micro-alloyed, high-strength steel or a polyphase, higher strength steel, wherein the profiled member has a torsionally yielding central longitudinal section with a double-wall cross-section and opposed torsion-proof end sections. The tubular profiled member can also be made of special steel such as a stainless high-alloy chrome steel.
