    摘要： A pneumatic suspension system for a vehicle is provided comprising a mounting arrangement for mounting a portion of the vehicle on a chassis; the mounting arrangement including at least one pneumatic spring to be arranged and coupled between the portion of the vehicle and the vehicle chassis. A vehicle state control system is provided that provides a pressure set value in the pneumatic spring and a pressure controller is arranged to a valve device alternatively for pressurizing or depressurizing the each pneumatic spring. The valve device comprises at least a first valve having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal. A support structure (102) distinct from the sealing edge (104) is provided arranged to providing supporting contact to the sealing face to counteract deformations of the sealing face.

    摘要： An air suspension system of a tandem axle assembly for a trailer includes a front axle air spring configured to be coupled to a front axle assembly of the tandem axle assembly and a rear axle air spring configured to be coupled to a rear axle assembly of the tandem axle assembly. The air suspension system further includes an air reservoir in fluid communication with the front axle air spring and the rear axle air spring and a ratio valve in fluid communication with the air reservoir, the front axle air spring, and the rear axle air spring. The ratio valve is positioned between the air reservoir and the front axle air spring. Further, the ratio valve is selectively operable to send a lesser amount of air from the air reservoir to the front axle air spring than to the rear axle air spring.

    摘要： A valve is disclosed for use in a system and process for controlling vehicle loading on a multi-axle vehicle and improving maneuverability. The valve partially exhausts air from an axle air bag when the vehicle is maneuvering at slow speed, reduces the load on the axle, and thus reduces damaging forces that affect tire wear and suspension component wear. The valve is a normally open, pilot operated valve that delivers supply air pressure upon receiving a sustained air pressure input of a pilot signal. Using an inversion function, the valve then dumps the delivery pressure through a high capacity exhaust upon receiving the pressure input of a secondary control signal. The hold function of the valve traps a reduced amount of delivery air pressure by closing the exhaust valve, and the hold function is actuated at a predetermined delivery pressure to trap a volume of air in the associated air suspension system until the valve member is returned to a supply position.
