Abstract
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.
