Abstract

An air spring assembly, for use on an associated vehicle suspension system having a mounting member and a damping member, includes spaced apart first and second end members. A flexible wall is secured on the first and second end members and defines a spring chamber therebetween. An isolator is supported on and sealingly engages the first end member. The isolator includes and isolator passage sealingly receiving the damping member. The isolator and the first end member at least partially form a first load transmission path such that a damping member load is distributed to the mounting member through the isolator and the first end member. The first end member at least partially forms a second load transmission path such that an air spring load is distributed to the mounting member through the first end member without substantial transmission through the isolator.
