Vehicle suspension systems.

摘要

A suspension system includes a chassis (2), first and second wheel supports (4) on opposite sides of the chassis, a first torsion bar (18) of generally U-shape which extends across the chassis and whose limbs (20) are connected to a respective wheel support (4) and a second torsion bar which extends across the chassis and whose ends are connected to a respective wheel support (4). The second torsion bar is so constructed that a torque applied to one end produces a torque in the opposite sense at the other end. The second torsion bar is divided into two portions, each of which has an outer limb (26) and an inner limb (28) which extend generally parallel to the length of the chassis and which are connected by a central limb (24). The two inner limbs (28) are connected by respective first pivotal connections (32) to a rigid bar (30) which extends between the inner limbs. The rigid bar (30) is connected by a second pivotal connection (36) to a rigid coupling (34) which is connected by a third pivotal connection (38) to the chassis (2).
