Tubular stabilizer bar for a vehicle chassis, and vehicle chassis comprising the tubular stabilizer bar

Abstract

The present invention relates to a tubular anti-roll bar for a vehicle chassis, produced from a metal tubular body, comprising a torsion spring portion, two limbs bent off from the torsion spring portion and a bending portion, arranged between the torsion spring portion and the respective bent limb and having an inside bending radius (IB) and an outside bending radius (OB), wherein the tubular anti-roll bar has a structure with grains with a grain size distribution and an average grain size, wherein the structure has a ratio between the average grain size in the bending portion of the inside bending radius (IB) in relation to the average grain size in the torsion spring portion in the range of 73% to 77%.
