| 发明名称 | Gas spring assembly for a vehicle suspension system | ||
| 摘要 | 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. | ||

| 主权项 | 1. 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. | ||
