ABSTRACT:
A roll stabilizing system for vehicle wheel spring suspension includes piston and cylinder units mounted between the chassis and respective suspension control arms at opposite sides of the vehicle to counteract roll of the vehicle sprung mass during cornering maneuvers. A single ended piston rod in each cylinder unit defines pressure chambers of unequal cross-sectional area and adverse affects of such inequality on the suspension system are prevented by a force compensating hydraulic circuit including additional piston and cylinder combinations responsive to hydraulic pressures sustained in the suspension control arm hydraulic units.
