摘要： A vehicle suspension system includes a gas spring. The gas spring includes a cylinder and a rod movable relative to the cylinder. The rod and the cylinder at least partially define a chamber having a variable volume and containing a first pressurized gas therein. The gas spring further includes an accumulator in communication with the chamber and containing a second pressurized gas therein. The gas spring provides a first spring rate when the first pressurized gas is pressurized below a threshold pressure and a second spring rate when the first pressurized gas is pressurized above the threshold pressure.

摘要： The suspension system for a trailer is disclosed. The suspension system includes a torsion axle and an air spring operating to accommodate a wide range of a load weight applied to the trailer without any change in ride comfort. The air spring can be adjusted for its pressure inside to cover a heavy load weight, while the torsion axle can have relatively softer spring materials therein to cover a light (and zero) load weight. The air spring and the torsion axle are arranged in series to provide adequate suspension based on the load weight.

摘要： A suspension system includes a spring assembly including a gas spring and an accumulator, and a controller. The accumulator is coupled to the gas spring and includes a bladder. The accumulator has a compressed state and an uncompressed state. The controller is configured to a) determine a target amount of gas in the spring assembly and b) adjust the amount of gas in the spring assembly towards the target amount of gas based on a pressure difference across the bladder.

摘要： A vehicle suspension is disclosed having a hydraulic actuator, a cylinder, a piston mounted inside the cylinder dividing the cylinder into a compression chamber and an extension chamber, and a supply hydraulic circuit connected to the actuator to supply the compression chamber and the extension chamber with working fluid. The supply hydraulic circuit includes a high-pressure line connected to a delivery port of a hydraulic pump, a low-pressure line connected to a suction port of the pump, a spool valve connected to the compression and extension chambers of the actuator and to the high-pressure line and to the low-pressure line to put the chambers of the actuator in communication with the lines of the supply hydraulic circuit, and a first pressure accumulator connected to the high-pressure line . The spool valve connects the compression chamber and/or the extension chamber of the actuator with the high-pressure line.

摘要： A fluid tank for storing a compressible fluid may have a translucent wall is disclosed. A light emitting diode (LED) may be configured to illuminate the wall. The fluid tank may comprise a tube and two end caps. The tube may be coupled to the end caps. Connecting rods disposed in the tube may be coupled to the end caps to squeeze the end caps onto the opposed ends of the tube. The LED may be disposed between one of the end portions of the tube and the end cap attached to that end portion of the tube. When the LED is illuminated, light is projected into the tube so that the tank now has a color to it.

摘要： A vehicle includes a body, a pair of front gas springs coupling a pair of front wheel end assemblies to the body, and a pair of rear gas springs coupling a pair of rear wheel end assemblies to the body. At least one of the rear gas springs includes a cylinder, a rod extending within the cylinder and movable relative to the cylinder, the rod and the cylinder together at least partially defining a chamber having a variable volume and receiving a first pressurized gas therein, and an accumulator in communication with the chamber and containing a second pressurized gas therein. The second pressurized gas within the accumulator is held at a threshold pressure creating a first spring rate when the first pressurized gas is below the threshold pressure and a second spring rate when the first pressurized gas is above the threshold pressure.
