Abstract
An air spring has first and second axially spaced end members with a flexible bellows sealingly clamped to the end members and extending therebetween and forming an intervening air chamber. A flexible elastomeric sleeve having at least one convolution resiliently mounts a rigid restraining cylinder to one of the end members. The cylinder extends co-axially along and outside of the bellows. The flexible sleeve is bonded or snap-fitted to the cylinder.
