Patent ID: 7900941

Claim:
A suspension system operable to provide a suspension between wheels and a frame of a vehicle, the system comprising one or more arm beams, each arm beam being substantially pivotally mounted to the frame at a proximate end of the arm beam and coupled substantially at a distal end of the arm beam to a guiding assembly operable to enable the arm beam to pivot in substantially a vertical direction and to be substantially restrained in lateral directions substantially perpendicular to the vertical direction, wherein each arm beam further includes: (a) a spring and damper assembly near or at its distal end for providing a dampened resilient mount for the suspension; (b) a wheel axle beam coupled to the one or more arm beams so that in operation a load borne by the wheels of the vehicle is transmitted directly substantially in-line with a central axis of the spring and damper assembly; and (c) a stabilizing arrangement coupled between the arm beam and the frame, the stabilizing arrangement being operable to at least partially resist a lateral rolling motion of the vehicle by way of torsional compliance exhibited by the stabilizing arrangement, the suspension system being configured so that the stabilizing arrangement is included between the proximate end of the one or more arm beams and their damper and spring assemblies and so that a portion of the stabilizing arrangement generally perpendicular to the arm beam is disposed between the arm beam and the wheel axle beam.
