Abstract
An improved airspring assembly includes a collapsible support member disposed within the pressurizable chamber of an airspring having a flexible sidewall. The support member is configured such that it extends and collapses along a longitudinal axis of the chamber responsive to pressurization and depressurization of the chamber, respectively. The support member also is configured such that it retains a substantially rigid outer perimeter, thereby restricting movement of the chamber's flexible sidewall toward the longitudinal axis when the chamber is depressurized. The support member also is configured such that it does not interfere with the full stroke of the airspring.
