Abstract

An automobile includes an active suspension system and a leveling system. The leveling system receives high pressure fluid from the active suspension system in order to change static vehicle height and compensate for static load changes.

First claim

What is claimed is:

1. A corner assembly comprising:
a top mount assembly;
a wheel assembly;
a shock absorber disposed between said top mount assembly and said wheel assembly, said shock absorber including a pressure tube defining a first fluid chamber and a piston slidably disposed within said pressure tube, said piston dividing said first fluid chamber into an upper working chamber and a lower working chamber;
an upper spring mount attached to said top mount assembly;
a lower spring mount attached to said wheel assembly;
a spring disposed between said upper spring mount and said lower spring mount; wherein
one of said upper spring mount and said lower spring mount is adjustable, said one of said upper spring mount and said lower spring mount includes: an inner housing assembly attached to one of said wheel assembly and said top mount assembly; an outer housing assembly attached to said spring; and a second fluid chamber disposed between said inner housing assembly and said outer housing assembly, said second fluid chamber being in fluid communication with said first fluid chamber defined by said pressure tube of said shock absorber.

2. The corner assembly according to claim 1 , wherein said inner housing assembly is attached directly to said shock absorber.

3. The corner assembly according to claim 1 , wherein said second fluid chamber is in fluid communication with said lower working chamber defined by said shock absorber.

4. The corner assembly according to claim 1 , wherein said fluid chamber is a sealed fluid chamber.

5. The corner assembly according to claim 1 , wherein said lower spring mount is adjustable:
said inner housing assembly is attached to said wheel assembly;
said outer housing assembly slidably engages said inner housing assembly.

6. The corner assembly according to claim 5 , wherein said inner housing assembly is attached directly to said shock absorber.

7. The corner assembly according to claim 5 , wherein said second fluid chamber is in fluid communication with said lower working chamber defined by said shock absorber.

8. The corner assembly according to claim 5 , wherein said fluid chamber is a sealed fluid chamber.

9. The corner assembly according to claim 1 , wherein said upper spring mount is adjustable:
said inner housing assembly is attached to said top mount assembly;
said outer housing assembly slidably engages said inner housing assembly.

10. The corner assembly according to claim 9 , wherein said inner housing assembly is attached directly to said shock absorber.

11. The corner assembly according to claim 9 , wherein said second fluid chamber is in fluid communication with said lower working chamber defined by said shock absorber.

12. The corner assembly according to claim 9 , wherein said fluid chamber is a sealed fluid chamber.

13. The corner assembly according to claim 9 , wherein said second fluid chamber is in fluid communication with said upper working chamber defined by said shock absorber.

14. The corner assembly according to claim 1 , wherein said second fluid chamber is in fluid communication with said upper working chamber defined by said shock absorber.
