Abstract: A roll correction system for use in a vehicle including a body, wheels, and a suspension coupling the body to the wheels includes a roll correction apparatus hydraulically actuated by a hydraulic signal indicative of a roll direction. A hydraulic signal source provides the hydraulic signal conditioned to indicate a roll position in response to a first steering direction. A countersteer correction element maintains the condition of the hydraulic signal to indicate the roll direction in response to countersteer in a second steering direction opposite the first steering direction as would occur, for example, in a skid.

Abstract: An anti-roll system for turn compensation in a vehicle generates a differential hydraulic signal in which a pressurizing potential corresponds to a first curve direction and a complementary return hydraulic potential. The system includes a pair of rear wheel cylinder and piston assemblies and a pair of front wheel cylinder and piston assemblies. A hydraulic circuit is connected to conduct the pressurizing potential to move the pistons in a first rear wheel cylinder and piston assembly and a first front wheel cylinder and piston assembly, while conducting the return signal to move the pistons in second front wheel cylinder and piston assembly and a second rear wheel cylinder and piston assembly. A hydraulic conductor directly connects corresponding ends of the rear wheel cylinder and piston assemblies to provide a hydraulic conduction between those assemblies in response to conduction of the differential hydraulic signal.

Abstract: The invention concerns a tilt correction system with at least one pair of cylinder and piston assemblies which are hydraulically operated. The extent of tilt correction is limited by grooves internal to the cylinders of the assemblies which short hydraulic potentials once the pistons of the assemblies have moved from a rest position to a position adjacent the grooves. A preferable arrangement includes connecting each assembly between an anti-roll bar and an axle.

Abstract: First and second cross-bars extend laterally across the width of a vehicle and are pivotally connected intermediate their lengths in scissors fashion. One end of each cross-bar is pivotally connected to a wheel support assembly which is in turn pivotally connected to the vehicle body by a spring and damper assembly. The other end of the first cross-bar is pivotally connected to the vehicle body by a hydraulic cylinder and piston assembly. The other end of the second cross-bar is pivotally connected via a lever to the actuator of a variable flow hydraulic valve. Lateral forces exerted by the wheels and cross-bars relative to the vehicle body during a turn operate the hydraulic valve to send a proportionate amount of hydraulic fluid to the upper or lower portion of the hydraulic cylinder to thereby prevent rolling of the vehicle body.
