Conventional roll stabiliser bars fitted to most modern vehicles work well to reduce vehicle body roll during cornering but also greatly increase single wheel and articulation stiffness, which reduce ride comfort and the vehicles ability to maintain equal wheel loading on uneven surfaces. Suspension designers struggle to find a balance between these ride parameters as each compromises the other. The Kinetic Reverse Function Stabiliser System or RFS can retain conventional bounce and damping methods and works by splitting the roll stabiliser bars using a simple cradle device incorporating a double acting hydraulic cylinders. These cylinders are connected using kinetics unique proprietary RFS arrangement . This arrangement passively frees the bars to allow articulation and single wheel type movements but will not permit vehicle body roll. This roll stiffness and "articulation looseness" are achieved simultaneously with neither mode effecting the other. This system requires no computers, pumps or motors.
