Abstract
An air spring that can be used in an air suspension system includes a hollow piston, a hollow shaft and a body. The hollow piston has a hole through it. The hollow shaft has a shaft interior volume in communication with the hole in the piston. The body has a body interior volume in communication with the hole in the hollow piston. The hole in the hollow piston in communication with the shaft interior volume and the body interior volume provides a total interior volume. Wherein, the total interior volume is greater than the body interior volume thereby providing a linearized spring rate.
