International Classification:

B60G 17/052
B60G 11/30
F16F 9/24
F16F 9/43

US Classification:

280 6157, 267 6428, 188297

Abstract:

A vehicle suspension system includes a pump, a gas spring, and an accumulator. The gas spring assembly includes a cylinder, a rod, and a chamber for supporting gas. The rod is coupled to the cylinder and moveable relative to the cylinder. The chamber is formed between the cylinder and the rod, where movement of the rod relative to the cylinder changes the volume of the chamber. The accumulator is configured for receiving, storing, and releasing potential energy from gas of the chamber. The accumulator is coupled to the chamber, and is in gaseous communication with the chamber such that a continuous body of gas extends between the chamber and the accumulator when the accumulator is receiving or releasing the potential energy.

US Classification:

280 6157, 267 6411, 267 6428

Abstract:

A gas spring for a vehicle suspension system includes a cylinder, a rod, and an accumulator. The rod is disposed within the cylinder, and relative movement between the rod and the cylinder changes the volume of a chamber formed between the rod and the cylinder. The accumulator is in gaseous communication with the chamber such that a continuous body of gas extends between the chamber and the accumulator.

Abstract:

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.

Abstract:

A vehicle has a vehicle body and a vehicle suspension system supporting the vehicle body. The vehicle suspension has a gas spring, and includes a cylinder, a rod, and an accumulator. The cylinder has a longitudinal axis. The rod is partially disposed within the cylinder and is movable relative to the cylinder along the longitudinal axis of the cylinder. The rod and cylinder together at least partially define a chamber having a variable volume that receives a first pressurized gas. The accumulator is in communication with the chamber and contains a second pressurized gas held at a threshold pressure creating a first spring rate opposing relative movement between the rod and cylinder when the first pressurized gas within the chamber is pressurized below the threshold pressure and a second spring rate when the first pressurized gas within the chamber is pressurized above the threshold pressure.

Abstract:

A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, the rod and the cylinder at least partially defining a chamber, and an accumulator in communication with the chamber. The rod and the cylinder are configured such that a relative movement therebetween changes the volume of the chamber. Gas in the chamber and the accumulator are configured to cooperate to at least partially provide a spring rate that varies based on at least one of a deflection and a spring force associated with at least one of the rod and the cylinder.

US Classification:

280 6157, 267 6411, 267 6426

Abstract:

A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, a relative movement between the rod and the cylinder changing the volume of a chamber formed between the rod and the cylinder, and an accumulator in communication with the chamber. Compression of gas in the chamber at least partially provides a first spring rate for deflections of the gas spring below a threshold, compression of gas in the chamber at least partially provides a second spring rate for deflections of the gas spring above the threshold, and the first spring rate is greater than the second spring rate.
