The control cylinder includes a housing body portion having two cylinder chambers which are divided by a partition wall portion; and a piston assembly which is formed by coupling two pistons with each other using a coupling rod. Two outer side control chambers and two inner side control chambers are connected to respective absorber chambers. Pressure receiving areas of outer side pressure-receiving surfaces and inner side pressure-receiving surfaces of the pistons and damping characteristics of the shock absorbers are set such that a direction in which the piston assembly moves in a region where an operation speed is low is opposite to a direction in which the piston assembly moves in a region where the operation speed is high.

Abstract: The object of this invention is to detect an abnormality of a roll-motion restricting device including a hydraulic circuit. It is possible to determine that a fluid leakage takes place if actual fluid pressure in fluid passages 72, 74 connecting the corresponding fluid chambers of front-wheel-side hydraulic cylinder 30 and rear-wheel-side hydraulic cylinder 60 is lower than a value determined by a lateral acceleration value of a vehicle. On the basis of a relationship between a state of rolling of the vehicle and the fluid pressure, the hydraulic circuit can be diagnosed for any abnormality. In the event of detection of an abnormality, solenoid-operated shut-off valves 100, 102 are closed to isolate the two hydraulic cylinders 30, 60 from each other, and isolate one of the hydraulic cylinders or a portion of the fluid passage, which suffers from the fluid leakage, from the other hydraulic cylinder, so that this other hydraulic cylinder can generate a fluid pressure difference depending upon the rolling state of the vehicle, enabling a stabilizer bar to generate a resilient force, whereby the deterioration of a roll-motion restricting effect can be made smaller, than in the case where the two hydraulic cylinders are disabled to normally function.

Abstract: A system is provided for use on large vehicles of the type wherein the vehicle frame (12) is supported on vehicle axle assemblies (14, 20, 22) through air bags (26, 30, 32), and each air bag has a lower end coupled to the lower end of an arm such as a swing arm (112) whose upper end is pivotally mounted on the frame. The height of the air bag is sensed by a pair of tilt sensors (50, 52), one on a tilt arm such as the swing arm (112), that has one end pivotally connected to the vehicle frame and an opposite end at least pivotally connected to the vehicle axle assembly. The other sensor senses tilt of the vehicle frame about an axis parallel to the axes of pivoting of the tilt arm. Each tilt sensor senses tilt of its location with respect to gravity, and the difference in tilt indicates air bag height.

Abstract: A rough terrain vehicle having a vehicle frame which maintains the vehicle platform and body in a relatively level position even when traversing slanted or uneven terrain is disclosed. The vehicle frame includes first and second forwardly-extending frame arms, and third and fourth rearwardly-extending frame arms. A central axle connects the frame arms at a midpoint of the vehicle and permits relative movement of the frame arms about pivot points at each side of the vehicle. Length-adjustable connecting members are provided at each side of the vehicle for controlling relative movement of the frame arms about the pivot points. A control mechanism is operatively associated with the connecting members for adjusting the relative positions of the frame arms so that the central axle remains relatively level even as the wheels follow the contour of slanted or uneven terrain. The vehicle platform and body are supported by the central axle so the vehicle body which carries the driver also remains level as the vehicle travels over the ground surface.
