Abstract
This invention concerns a pneumatic spring consisting of a hose roll bellows of elastomer material which is equipped, in particular, with stiffening supports. The ends of the hose roll bellows are pushed onto a connecting element and attached there by a radially ductile clamping ring particularly made out of metal. According to the invention, the connecting element and/or clamping ring are made thicker with a covering elastomer strip in the area of clamping. The elastomer strip is a component which is separate from the hose roll bellows. Several variants are presented.
