Abstract

An assembly for an air spring includes an outer gaiter defined in part by an interior portion, an inner gaiter defined in part by an exterior portion, at least one floating ring extending from a first floating ring end to a second floating ring end, the first floating ring end coupled with the inner gaiter and the second floating ring end is coupled with the outer gaiter, where the at least one floating ring allows the outer gaiter to move relative to the inner gaiter.

First claim

What is claimed is:

1. An air spring assembly comprising:
a piston;
an inner gaiter coupled to the piston;
an outer gaiter; and
a floating ring coupled between the inner gaiter and the outer gaiter.

2. The air spring assembly as recited in claim 1 , wherein the inner gaiter is configured to telescope within the outer gaiter.

3. The air spring assembly as recited in claim 1 , wherein a first diameter of the outer gaiter is greater than a second diameter of the inner gaiter.

4. The air spring assembly as recited in claim 1 , wherein the floating ring comprises:
a first flange coupled to the inner gaiter; and
a second flange coupled to the outer gaiter.

5. The air spring assembly as recited in claim 1 , further comprising:
one or more of clamps, snap fit, a weld joint, or overmolding,
wherein the inner gaiter is coupled to the floating ring by the one or more of clamps, snap fit, weld joint, or overmolding.

6. The air spring assembly as recited in claim 1 , further comprising:
one or more of clamps, snap fit, a weld joint, or overmolding,
wherein the outer gaiter is coupled to the floating ring by the one or more of clamps, snap fit, weld joint, or overmolding.

7. The assembly as recited in claim 1 , wherein the floating ring comprises a top end and a bottom end, and
wherein the top end of the floating ring is coupled to a top end of the inner gaiter and the bottom end of the floating ring is coupled to a bottom end of the outer gaiter.

8. An air spring assembly, comprising:
an outer gaiter;
a floating ring connected to the outer gaiter; and
an inner gaiter connected to the floating ring,
wherein the outer gaiter and the inner gaiter move relative to one another in a telescoping manner when force is applied to the air spring assembly.

9. The air spring assembly of claim 8 , wherein the floating ring comprises:
a plurality of flanges, the plurality of flanges comprising a first flange
integrally formed as part of a floating ring first end and connected to the inner gaiter and a second flange
integrally formed as part of a floating ring second end and connected to the outer gaiter,
wherein the first flange extends away from the floating ring in a direction opposite to a direction in which the second flange extends away from the floating ring.

10. The air spring assembly of claim 8 , further comprising:
a piston connected to the inner gaiter; and
a guide tube connected to the outer gaiter.

11. The air spring assembly of claim 10 , further comprising:
an end of the inner gaiter connected to the piston; and
an end of the outer gaiter connected to the floating ring,
wherein the end of the inner gaiter connected to the piston is disposed at a longitudinal position that is substantially the same as the end of the outer gaiter connected to the floating ring when the air spring, assembly is in a compressed position.

12. The air spring assembly of claim 10 , wherein as the air spring assembly is changed between the compressed position and a decompressed position, the piston and the guide tube move relative to one another, and the floating ring moves relative to both the piston and the guide tube.

13. The air spring assembly of claim 8 , the floating ring is formed to have a Z-shaped cross section.

14. The air spring assembly of claim 8 , wherein a portion of the outer gaiter circumscribes at least a portion of the inner gaiter, independently of a position of the floating ring.

15. The air spring assembly of claim 8 , wherein the floating ring circumscribes a portion of the inner gaiter.

16. The air spring assembly of claim 8 , wherein a portion of the outer gaiter circumscribes the floating ring.

17. The air spring assembly of claim 8 , wherein a portion of the outer gaiter circumscribes at least a portion of the inner gaiter.
