Abstract
() A roll control system () for installation between axially aligned wheels of a motor vehicle, the roll control system comprising a torsion bar (); a damper () attached to one end () of the torsion bar and attachable to one of the wheels; and attachment means () attached to the other end () of the torsion bar and attachable to the other wheel; wherein the damper comprises an axially extending cylindrical housing (); a piston () slidably mounted inside the housing; a piston rod () connected to the piston, extending out of one end () of the housing, and movable in an axial direction relative to the housing; a floating piston () slidably mounted in the housing between the piston and the other end of the housing; a compensation chamber () between the floating piston and the other end () of the housing containing a first pressurised fluid; a compression chamber () between the floating piston and the piston containing a second pressurised fluid; a rebound chamber () between the piston and the one end of the housing containing the second pressurised fluid; valve means () on the piston allowing restricted flow of the second pressurised fluid between the compression chamber and the rebound chamber; a rebound stop () positioned in the rebound chamber between the piston and the one end of the housing and providing a spring-effect on the movement of the piston towards the one end of the housing; and a compression stop () providing a spring-effect on the movement of the piston towards the floating piston. Provides an improved passive roll controle system.
