Semi-trailing arm for twist beam rear axle is made from pipe using internal high-pressure technique and wall thickness in tubular fitting is thicker than that in pipe

摘要

The device has a tubular fitting (6) on the inner end that ends in an end surface (11) to which a transverse torsion profile (5) can be butt welded. The semi-trailing arm is made from a pipe using the internal high-pressure technique and the wall thickness in the fitting is thicker than that in the pipe.
