The stabilizer has a chemical composition containing at least C: 0.15% by mass or more to 0.39% by mass or less, Mn, B, and Fe, and also has a metal structure 90% or more of which is a martensite structure.

A torsion bar spring is disclosed. The torsion bar spring can include a first elongated spring bar made of a resiliently flexible material. The first elongated spring bar can have a first coupling interface portion at a distal end and an interior opening oriented along a longitudinal axis. The torsion bar spring can also include a second elongated spring bar made of a resiliently flexible material. The second elongated spring bar can have a second coupling interface portion at the distal end. The second elongated spring bar can be disposed at least partially in the interior opening of the first elongated spring bar. The first and second elongated spring bars can be directly coupled to one another at the first and second coupling interface portions such that uncoupled portions of the first and second elongated spring bars are rotatable relative to one another about the longitudinal axis.

The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.
