Airsprings

摘要

A high ratio L/D sleeve type rolling lobe airspring is modified to provide column stabilization and correct a "weinering" effect by reason of a collar mounted at the plug end of the airspring sleeve. The collar prevents the inflated sleeve from rolling over a mounting ring that retains the sleeve on the plug. In another embodiment a rigid member is mounted inside of the airspring to limit the kink effect of the sleeve at a full jounce position such that upon being repressurized under restrained load the sleeve returns to an axially symmetric configuration.
