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.

A gas spring for a vehicle suspension system, comprising:
- a cylinder;
- a rod disposed within the cylinder, wherein a relative movement between the rod and the cylinder changes the volume of a chamber formed between the rod and the cylinder;
- and
- an accumulator in communication with the chamber, wherein compression of gas in the chamber at least partially provides a first spring rate for deflections of the gas spring below a threshold, wherein compression of gas in the chamber at least partially provides a second spring rate for deflections of the gas spring above the threshold, and wherein the first spring rate is greater than the second spring rate.
A gas spring for a vehicle suspension system, comprising:
- a cylinder;
- a rod disposed within the cylinder, wherein a relative movement between the rod and the cylinder changes the volume of a chamber formed by the rod and the cylinder;
- an accumulator in communication with the chamber;
- and
- a sensor coupled to at least one of the rod and the cylinder, wherein the sensor is configured to provide a signal indicative of a ride height of the vehicle suspension system based upon the relative position of the rod and the cylinder.
