Abstract: A suspension device for a wheeled vehicle with a plurality of air springs is described. Two main air chambers of two air springs of a respective vehicle axle are connected together via a transverse air chamber which forms an intermediate volume. A compressor arranged between the two transverse air chambers is connected to the first transverse air chamber via a first connecting line in which a first switchable valve is arranged, and to the second transverse air chamber via a second connecting line in which a second switchable valve is arranged, so that direct filling/direct evacuation of the intermediate volumes of the two transverse air chambers is possible.

Abstract: Vehicle suspension system applicable to vehicles provided with rolling arrangements that have a resistance to the roll, pitch vertical rebound, and axle crossing movement such that allows a weight distribution on every rolling arrangement. The rolling arrangements are connected to a central device that is attached to the vehicle body. The central device includes elastic devices that receive the movements and forces originated in each rolling arrangement because of the weight variations and dynamic forces created when the vehicle is traveling. Vertical forces and movements detected in the vehicle wheels are transmitted to the central device through hydraulic and/or mechanical devices.

Abstract: A hydraulic control apparatus including a housing including first sliding-related portions; a piston assembly including second sliding-related portions which cooperate with the first sliding-related portions to provide pairs of first and second sliding-related portions; and elastically deformable sealing members each of which is supported by one of the first and second sliding-related portions of a corresponding one of the pairs, such that the each sealing member is slideable on the other of the first and second sliding-related portions. The pairs of first and second sliding-related portions and the sealing members cooperate with each other to separate an inner space of the housing into hydraulic chambers. When the piston assembly is moved in the housing in a movement direction, the each sealing member supported by the one of the first and second sliding-related portions is slid on the other of the first and second sliding-related portions, and a volume of each of the hydraulic chambers is changed. At least one pair of first and second sliding-related portions of the pairs of first and second sliding-related portions exhibits, when the piston assembly is positioned, in the movement direction, at different positions relative to the housing, different resistances to the movement of the piston assembly relative to the housing.

Abstract: A suspension system includes an air spring and a shock absorber disposed between the sprung and unsprung portions of a vehicle. A vehicle height sensor sends signals to a control system which adjusts the height of the vehicle by increasing or decreasing the air pressure within the spring. This same air pressure is provided to the shock absorber in order to increase the damping rate for high loads and decrease the damping rate for low loads. The air pressure to the shock absorber is provided to a valve assembly which controls fluid flow between the working chamber of the shock absorber and a reserve chamber.
