Air-spring assembly

Abstract

An air-spring assembly includes a flexible bellows extending from a top end to a bottom end and enclosing an air-spring chamber between the top end and the bottom end, a first panel partially defining the air-spring chamber and movable in response to a pressure of the air-spring chamber, an enclosure partially defining a working chamber fluidly isolated from the air-spring chamber, a second panel partially defining the working chamber and movable relative to the enclosure, and a linkage member fixed relative to the first panel and to the second panel and defining a fixed distance between the first panel and the second panel. The top and bottom ends are fixable to a frame and a wheel of a vehicle, respectively. A volume of the air-spring chamber varies with movement of the bottom end relative to the top end. Movement of the second panel changes a volume of the working chamber.
