ABSTRACT:
A torsion bar springing means for a suspension system, in which angular motions of first and second control members of the suspension linkage are respectively coupled to separate points of securement on the torsion bar, giving rise to a differential torsional spring resistance to displacements in the vehicle suspension system. This double-acting arrangement differs from conventional single-acting torsion bar springing mechanisms in which a spring device is interposed between an attachment point on the suspension linkage and an attachment point on the chassis of the vehicle. Advantages of simplicity, flexibility of adjustment and economy result from a Differential Torsion Spring mechanism according to the invention, which resists deflection of the suspension from within its geometric linkage.
