Solid girdle hoop for an air spring

摘要

A fluid device such as an air spring (2) includes a pair of parallel spaced end members (3,4) and an elastomeric sleeve interposed therebetween to define a fluid pressure chamber therein. A girdle hoop (1) is formed of cold rolled solid steel in a toroidal configuration and is molded into the elastomeric sleeve parallel and preferably spaced equidistant from the end plates.
