Abstract
An end member assembly includes a first end member and a second end member. An air spring assembly can be formed using an end member assembly on one end thereof. A method is also described.
Claims24
An air spring assembly comprising:
- a first end member including a first end and a first side wall;
- a second end member spaced from said first end member;
- a flexible wall including opposing first and second ends, said first end disposed along said first end member and including a first wall portion, a second wall portion spaced outwardly from said first wall portion, and a flexed wall portion disposed between said first and second wall portions of said first end, said second end of said flexible wall secured on said second end member;
- a retaining member disposed along said first wall portion of said flexible wall opposite said first side wall of said first end member;
- and,
- a third end member positioned adjacent said first end member, said third end member disposed in abutting engagement with said first end member and said flexed wall portion of said first end of said flexible wall.

A method of assembling an air spring, said method comprising:
- a) providing:
- a first end member including a first end wall and a first side wall extending approximately transverse to said first end wall, said first side wall having an outermost dimension;
- a second end member being cooperative with said first end member and including a second side wall having a greater outermost dimension than said first side wall of said first end member and a second end wall extending approximately transverse to said second side wall;
- a third end member;
- and,
- a flexible wall extending longitudinally between opposing first and second ends, said flexible wall including a first wall portion disposed along said first end, a second wall portion spaced longitudinally-inwardly from said first end and a third wall portion disposed between said first and second wall portions;
- b) positioning said flexible wall along said first side wall of said first end member such that said first wall portion is capable of extending beyond said first end member with said second wall portion disposed along said first side wall of said first end member;
- c) providing a first retaining member and securing said second wall portion of said flexible wall along said first end member using said first retaining member;
- d) folding said first wall portion of said flexible wall outwardly of said second wall portion such that said third wall portion forms an outermost longitudinal extent of said flexible wall;
- e) providing a second retaining member and securing said first wall portion along said first end member using said second retaining member;
- f) positioning said second end member in cooperative engagement along said first end member such that said second end wall is in abutting engagement with said third wall portion of said flexible wall and securing said second end member along said first end member;
- and,
- g) securing said second end of said flexible wall along said third end member.

A method of assembling an air spring, said method comprising:
- a) providing an end member assembly including a first component and a second component, said first component including a side wall and a first outermost radial extent, and said second component including an end wall and a second outermost radial extent that is greater than said first outermost radial extent;
- b) providing a piston including an outside wall;
- c) providing a sleeve including first and second ends;
- d) placing a first section of said sleeve adjacent said first end along said side wall and bordering said first outermost radial extent of said end member assembly;
- e) securing said sleeve along said side wall;
- f) folding a second section of said sleeve away from said first section to form a folded section;
- g) positioning said second component in abutting engagement with said first component and said folded section and securing said first component to said second component;
- and,
- h) securing said piston along said second end of said sleeve such that a portion of said sleeve is disposed along said outside wall of said piston.
