Abstract
An air spring has a pair of spaced end members for mounting the spring at spaced locations on a structure. A flexible sleeve of elastomeric material is sealingly engaged with the end members and forms a pressurized fluid chamber therebetween. A post is mounted on one of the end members and extends into the fluid chamber. A shock absorbing two-piece bumper includes a rigid base which is formed with an axial opening and is seated upon one of the end members with the post extending into the opening. An elastomeric member is mounted within the axial opening of the rigid base member and is snap-fitted onto the post. The upper end of the elastomeric member extends outwardly over the upper end of the base to engage the opposite end member upon the air spring failing or experiencing a large deflection. The two-piece bumper provides a high load carrying capability with low deflection and replaces the heretofore used single member elastomeric bumper.
