摘要： A vehicle suspension control system is disclosed for use in load-carrying vehicles. The system controls a response of a suspension cylinder configured to support a main body of a vehicle in relation to a ground-contacting portion of the vehicle. A main accumulator is configured to contain a main compressible gas volume and is fluidly connected with the suspension cylinder. An auxiliary accumulator is configured to contain an auxiliary compressible gas volume. A valve is configured to selectively fluidly connect the auxiliary accumulator to the suspension cylinder. When the valve is open, compressing the suspension cylinder compresses both the main compressible gas volume and the auxiliary compressible gas volume. When the valve is closed, the auxiliary accumulator is fluidly isolated from the suspension cylinder. A processor is configured to automatically open or close the valve using a solenoid actuator based on one or more operating parameters of the vehicle.

摘要： An improved hydraulic suspension unit has a springing force and rebound damping which are related to one another so as to allow certain wheel movements to occour without the resistance of rebound damping. A primary springing force provided by a pressurized gas, a coil spring and elastomer or any combination therof acts directly through the shock fluid via a floating piston, bladder or flexible diaphragm. The primary spring force acts directly through the shock fluid, and thus directly on a rebound damping valve so that the rebound damping valve is only able to dampen the stored energy. The spring provides a maximun in tuning and adjustment capability for varying conditions with easily variable reload and rate. The rebound damping valve can also be adjusted, both to determine the maximum rebound resistance when damping springing energy, and thus maximum shock shaft velocity, and to determine the magnitude of th shaft movements that are allowed to occur without rebound damping. Compression damping can also be adjusted independently of rebound damping, and provides very high flow rates, and a much more desirbale compression damping control. These adjustments can be made external to the suspension unit and require no disassembly. A lightweight vehicle is disclose which utlizes the improved hydraulic suspension unit.

摘要： An apparatus for stabilizing a material handling vehicle which enables or disables a vehicle's suspension system. Pilot-to-open check valves are mounted on hydraulic cylinders secured between the axle and frame of the vehicle. In a first embodiment, a pneumatically actuated check valve is opened or closed to permit or prevent fluid communication between the hydraulic cylinders. The absence of pneumatic pressure in the pneumatic circuit causes the check valves to close, thereby locking the axle to the frame for stability. The presence of pneumatic pressure in the circuit opens the check valves to permit fluid communication between the cylinders. In an alternative embodiment, a second electro-hydraulic circuit is provided in place of the pneumatic circuit for opening and closing pilot-to-close check valves mounted on the hydraulic cylinders.

摘要： The present invention relates to an improved vehicle suspension system. More particularly, the present invention relates to an independent suspension system for light and medium duty trailers which utilizes a flexible bladder mounted between the vehicle frame and the axle. The flexible bladder is housed within a casing to control the flow of air into the bladder and to provide for flexible movement of the axle relative to the vehicle frame. In the preferred embodiment, the flexible bladder is a traditional break-chamber housing and multiple break-chamber housings may be utilized to increase the load-carrying capacity of the trailer.

A primary springing force provided by a pressurized gas, a coil spring, an elastomer or any combination thereof acts directly through the shock fluid via a floating piston, bladder or flexible diaphragm. The primary spring force acts directly through the fluid, and thus directly on a rebound damping valve so that the rebound damping valve is only able to dampen the stored energy of the spring, allowing other extension movements of the suspension unit to take place undamped, if these movements are not caused by the spring returning stored energy. The spring provides a maximum in tuning and adjustment capability for varying conditions with easily variable reload and rate. The rebound damping valve can also be adjusted, both to determine the maximum rebound resistance when damping springing energy, and thus maximum shock shaft velocity, and to determine the magnitude of the shaft movements that are allowed to occur without rebound damping.

摘要： An air spring apparatus for a vehicle suspension. An active air cylinder and piston of the apparatus are connected in series with the vehicle suspension. An inactive air cylinder constituting an air column extension of the active air cylinder is connected in series with the active air cylinder by an air conduit. The spring rate of the system is automatically adjustable to produce optimum isolation of impulsive forces and to maintain the forces on the road under dynamic conditions essentially equal to those forces under static conditions.
