Abstract

An annular spring assembly includes an annular spring, an annular first container including a first well and an annular second container including a second well. The first well and second well open towards one another and hold the annular spring therebetween. The second well is configured to telescopically receive the first well when the annular spring is compressed.

First claim

What is claimed is:

1. An annular spring assembly, comprising:
an annular spring;
an annular first container including a first well; and
an annular second container including a second well, said first well and said second well being open towards one another and holding said spring therebetween, said second well being configured for telescopically receiving said first well when said spring is compressed, said annular second container including a second inner wall defining an inner boundary of said second well and a second through-hole and said annular first container including a first inner wall defining an inner boundary of said first well and said first inner wall further defining a recess configured to receive said second inner wall when said spring is compressed.

2. The annular spring assembly according to claim 1 , wherein at least one of said annular spring, said annular first container and said annular second container has a toroidal shape.

3. The annular spring assembly according to claim 2 , wherein said annular spring, said annular first container and said annular second container each have a geometric center, said geometric centers being aligned on a common axis.

4. The annular spring assembly according to claim 2 , wherein said annular first container has a first outer radial distance and said annular second container has a second inner radial distance, said second inner radial distance being greater than said first outer radial distance.

5. The annular spring assembly according to claim 4 , wherein said annular first container has a first inner diameter and said annular second container has a second inner diameter, said first inner diameter being equal to said second inner diameter.

6. The annular spring assembly according to claim 5 , wherein said first inner diameter is configured to prevent further telescoping of said first well within said second well.

7. The annular spring assembly according to claim 4 , wherein said first well has an inner well diameter and said annular second container has a second inner diameter, said inner well diameter being greater than said second inner diameter.

8. The annular spring assembly according to claim 7 , wherein at least one gap is formed between said annular spring and at least one of said first well and said second well.

9. The annular spring assembly according to claim 8 , wherein said annular spring is configured to expand into said at least one gap when compressed.

10. The annular spring assembly according to claim 9 , wherein said annular spring includes at least one of an air spring, a urethane component, a microcellular urethane component, and a rubber component.

11. The annular spring assembly according to claim 1 , wherein said second well is configured to telescopically receive said first well such that said annular spring does not expand outside of said second well.

12. A spring system, comprising:
a first spring assembly and a second spring assembly, each of said first spring assembly and said second spring assembly respectively including:
an annular spring;
an annular first container including a first well and a first side opposing said first well; and
an annular second container including a second well and a second side opposing said second well, said first well and said second well being open towards one another and holding said spring therebetween, said second well being configured for telescopically receiving said first well when said spring is compressed,

said second side of said second container of said second spring assembly being positioned adjacent to said first side of said first container of said first spring assembly, said annular second container including a second inner wall defining an inner boundary of said second well and a second through-hole and said annular first container including a first inner wall defining an inner boundary of said first well and said first inner wall further defining a recess configured to receive said second inner wall when said spring is compressed.

13. The spring system according to claim 12 , wherein said first spring assembly and said second spring assembly each have a toroidal shape with a through-hole.

14. The spring system according to claim 13 , wherein said first spring assembly has a first geometric center and said second spring assembly has a second geometric center, said first geometric center and said second geometric center lying on a common axis.

15. The spring system according to claim 14 , further including a damper placed along said common axis.

16. A method of forming a spring system, said method comprising the steps of:
providing a first spring assembly and a second spring assembly, each of said first spring assembly and said second spring assembly respectively including:
an annular spring;
an annular first container including a first well and a first side opposing said first well; and
an annular second container including a second well and a second side opposing said second well, said first well and said second well being open towards one another and holding said spring therebetween, said second well being configured for telescopically receiving said first well when said spring is compressed; and

positioning said second side of said second container of said second spring assembly adjacent to said first side of said first container of said first spring assembly, said annular second container including a second inner wall defining an inner boundary of said second well and a second through-hole and said annular first container including a first inner wall defining an inner boundary of said first well and said first inner wall further defining a recess configured to receive said second inner wall when said spring is compressed.

17. The method according to claim 16 , wherein said first spring assembly and said second spring assembly each have a toroidal shape with a through-hole.

18. The method according to claim 17 , further including the step of aligning a first geometric center of said first spring assembly and a second geometric center of said second spring assembly on a common axis.

19. The method according to claim 18 , further including the step of holding said first spring assembly and said second spring assembly together by placing a damper through said through-holes along said common axis.

20. The method according to claim 16 , further including the step of compressing at least one of said first spring assembly and said second spring assembly.
