Abstract: 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.

Abstract: A vehicle suspension system includes a vehicle body, a plurality of wheels arranged in lateral and longitudinal spaced relation to support the vehicle body. Two hydraulic rams are between each wheel and the vehicle body, with one ram of each wheel connected by a fluid circuit with a ram of the laterally adjacent wheel and the other ram of each wheel connected by a fluid circuit to the ram of the longitudinally adjacent wheel. A respective sensor for each wheel is adapted to generate a signal indicative of the positional relation of that wheel relative to the vehicle body. A programmed controller is arranged to receive the signals from each sensor and compare the positional relation of the body with respect to a preset datum position, and a fluid adjustment device is operable in respect to a detected variation of the positional relation from the datum position to adjust the volume of fluid in the relevant fluid circuit to correct the positional relation if required.

Abstract: A vehicle having a load support body, and a pair of front ground engaging wheels and a pair of rear ground engaging wheels connected to the body to support the body is shown, with each wheel being displaceable relative to the body in a generally vertical direction. A double acting fluid ram has a piston and is interconnected between each wheel and the body. Each ram includes a first and second fluid filled chamber on opposite sides of the ram piston, with the first and second chambers varying in volume in response to vertical movement between the respective wheel and the body. First conduits provide fluid communication between the first chambers of the front and rear rams on the same side of the vehicle, and second fluid conduits provide communication between the second chambers of the front and rear rams on the same side of the vehicle. A first further fluid communicating conduit interconnects the first fluid conduit on each side of the vehicle to the respective second fluid conduit on the opposite side of the vehicle, to thereby provide two fluid circuits, each including one of the first conduits, one of the second conduits, and one of the first further conduits interconnecting the first and second conduits. Each circuit is adapted to resiliently vary the fluid capacity of the circuit by an accumulator to accommodate fluid displaced from rams in that circuit with a resultant pressure rise in the circuit.

Abstract: 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).

Abstract: A vehicular suspension system for a vehicle includes at least one pair of transversely adjacent front surface engaging members and at least one pair of transversely adjacent back surface engaging members for supporting a body of the vehicle. The suspension system further includes a first force transmitting device interconnecting the at least one pair of transversely adjacent front surface engaging members, and a second force transmitting device interconnecting the at least one pair of transversely adjacent back surface engaging members. The force transmitting devices transfer forces between the interconnected surface engaging members. Each force transmitting device includes an adjustment device for progressively varying the magnitude and direction of the force transferred between the associated surface engaging members by the force transmitting devices as a function of the relative positions of and the load applied to at least two pairs of the interconnected surface engaging members. The adjustment devices are functionally linked such that the magnitude and the direction of the force transmitted between associated surface engaging members by each of the force transmitting devices is progressively varied to thereby maintain and return the attitude of the vehicle to a position that is at least substantially parallel to the average surface plane supporting the vehicle.

Abstract: A vehicle having a suspension comprising a double acting ram (13, 14, 17, 18) connecting each wheel (1, 2, 3, 4) independently to the body (5) of the vehicle, each ram (13, 14, 17, 18) having respective first (13a, 14a, 17a, 18a) and second (13b, 14b, 17b, 18b) chambers that vary in volume as the wheels move relative to the vehicle body (5). Each front wheel ram (13, 18) is connected to the diagonally opposite rear wheel ram (14, 17) by a respective pair of conduits (8, 10) and (8a, 10a) arranged so the first chamber (13a, 18a) of one wheel is connected to the second chamber (14b, 17b) of the other wheel. Each first and second chamber and the conduits connected thereto are filled with fluid and independent of external fluid and pressure sources. Diagonal interconnection of the front and rear rams minimizes roll movement in a lateral direction and pitch movement in the longitudinal direction of the vehicle.

Abstract: A vehicle having a body 25 supported respective pairs of front and rear wheels, 30, 31, 32, 33, two piston and cylinder units, 23-24, 35-36, 37-38, 34-39, being associated with each wheel and connected between the wheel 30 and body 25 so the piston moves in the cylinders in response to relative movement between the wheel and the body. An individual fluid circuit 40, 41, 42, 43, connecting one piston and cylinder unit 23 of each wheel 30 to a corresponding unit 34 longitudinally spaced therefrom on the same side of the vehicle, and the other piston and cylinder unit 24 of each wheel to a corresponding unit 35 on the transversely opposite side of the vehicle. This arrangement results in the fluid pressure in any two piston and cylinder units interconnected by an individual fluid circuit being equal, and relative movement between any one wheel and the vehicle body induces an opposite relative movement between the vehicle body and the wheel in fluid circuit therewith to maintain tractive ground engagement of all wheels.
