TWIST-AXLE OF VARIABLE WALL THICKNESS

摘要

The invention relates to a twist-axle that includes a cross-beam member and two trailing arms, each trailing arm rigidly secured to the cross-beam member in one of t wo connection regions of the cross-beam member or formed integrally with and extending fro m one of the two connection regions. The cross-beam member is formed from a tubular blank and has a torsionally elastic central portion and two torsionally stiff connection regions. The cross-beam member has a wall thickness that varies longitudinally along the length of t he cross-beam member from the torsionally elastic central portion to each of the torsional ly stiff connection regions.
