摘要: A roll control system for a vehicle suspension system and a method for controlling the control system is disclosed. The vehicle has at least one pair of laterally spaced front wheel assemblies and at least one pair of laterally spaced rear wheel assemblies. Each wheel assembly includes a wheel and a wheel mounting permitting wheel movement in a generally vertical direction relative to the vehicle body, and vehicle support means for providing at least substantially a major portion of the support for the vehicle. The roll control system includes: wheel cylinders respectively locatable between each wheel mounting and the vehicle body. Each wheel cylinder includes an inner volume separated into first and second chambers by a piston supported within, and first and second fluid circuits respectively providing fluid connection between the wheel cylinders by fluid conduits. Each of the fluid circuits provide fluid communication between the first chambers on one side of the vehicle and the said second chambers on the opposite side of the vehicle to thereby provide roll support decoupled from a warp mode of the vehicle suspension system by providing a roll stiffness about a level roll attitude whilst simultaneously providing substantially zero warp stiffness. The method includes bypassing fluid flow from at least a substantial portion of the conduits during predetermined wheel inputs to the control system to thereby minimize line damping and/or fluid inertia effects on the damping of the control system.

摘要: A vehicle suspension control system that allows substantially vertical motion of each wheel relative to the vehicle body includes front and rear resilient support means for supporting the body, a front roll stabilization assembly interconnecting at least one forward pair of wheels and a rear roll stabilization assembly interconnecting at least one rearward pair of wheels. Each roll stabilization assembly includes at least one lateral torsion bar (2) and a double-acting hydraulic actuator (3) interconnected to the at least one lateral torsion bar (2), the front and rear hydraulic actuators (3) being interconnected by first and second fluid conduits (5). Roll moments applied to the vehicle body generate pressure within the fluid conduits (5) thereby transmitting the roll moment into each lateral torsion bar (2). Warp motions of the wheels generate flow along the fluid conduits (5) resulting in a displacement of one hydraulic actuator (3) in a proportional and opposite direction to the other hydraulic actuator (3). The front and rear roll stabilization assemblies provide roll stiffness during both roll and warp motions while at the same time providing substantially zero warp stiffness. The system includes an hydraulic fluid supply means (12) and fluid conduit valve means (13) for selectively communicating the fluid conduits (5) with the hydraulic fluid supply means (12) to regulate the average pressure in both fluid conduits (5).

摘要: A suspension system is provided for a vehicle having a chassis supported on at least one front pair of laterally spaced wheels and at least one rear pair of laterally spaced wheels. The suspension system includes vehicle support devices for supporting the chassis above each pair of wheels, and roll moment reaction devices for providing location of the chassis about a substantially level roll attitude. The roll moment reaction devices include a respective roll attitude control mechanism for each pair of laterally spaced wheels for passively controlling the position of the wheels relative to each other and the chassis. Each roll attitude control mechanism is connected to at least one other roll attitude control mechanism by roll mechanism interconnection devices. The roll mechanism interconnection devices are arranged such that the roll moment reaction devices resist roll of the vehicle chassis with respect to the wheels, while simultaneously permitting cross-axle articulation motions of the wheels. The vehicle support devices for at least one pair of wheels include at least a first support for supporting at least a portion of the load on the vehicle support devices. The first support provides substantially zero roll stiffness of the vehicle. The roll moment reaction devices are separate devices from the vehicle support devices, thereby providing substantially zero load carrying capacity.
