Abstract
A suspension system includes a torsion bar having at least one adjuster arm. The adjuster arms extend radially from the torsion bar to contact respective stop members when the torsion bar is subjected to a predetermined torsion. When an adjuster arm contacts a stop, a portion of the torsion bar is rotationally fixed and the effective length of the torsion bar is reduced. By reducing the effective length of the torsion bar, the effective spring, rate of the torsion bar is increased. The present invention therefore provides a suspension system for a vehicle which can enhance riding comfort and handling by modifying the effective length of the torsion bar to achieve multiple spring constants with a single constant diameter torsion bar.
