Abstract

The invention is directed to an air spring having a sleeve-type flexible member made of elastomeric material. The flexible member has end sections which are attached to connecting parts by radially plastically deformed clamping rings. The clamping ring attaches an end section of the sleeve-type flexible member to a particular connecting part with a friction-contact connection to enable the attachment of the flexible member to withstand higher pull-out forces.
