Abstract:
A suspension system for a vehicle having a body and two wheels on opposite sides thereof, the system comprising a pair of suspension arms for supporting the two wheels, a pivot connecting each suspension arm to the vehicle body, and a pair of struts each arranged for connection between the vehicle body and one of the suspension arms, at a respective distance from the pivot, to control rotation of the suspension arm about its pivot thereby to control vertical movement of the respective wheel relative to the vehicle body,wherein each strut comprises a cylinder and a piston which together define a working chamber having a volume, the piston having a working area and being movable relative to the cylinder to change the volume, the two working chambers are interconnected with each other; the struts are asymmetrically arranged; and the cross sectional areas of the pistons and the distances between the struts and the respective pivots are arranged such that equal vertical movements of the wheels in the same direction produce equal but opposite changes in the volume of the respective working chambers.
