Abstract

Systems for inspecting and servicing a tire assembly are provided. In one embodiment, a tire assembly service cart is provided that includes a tire assembly support structure. The tire assembly support structure may include a side support member that is positioned to support a side of the tire assembly. The tire assembly support structure may also include a first bottom support member positioned to support a bottom portion of the tire assembly. The side support member may include a first roller and the first bottom support member may include a second roller. Further, the first and second rollers may be positioned to allow the tire assembly to rotate around a rotation axis while supported by the tire assembly support structure.

First claim

The invention claimed is:

1. A tire assembly service cart comprising:
at least one tire assembly support structure, the at least one tire assembly support structure comprising:
a side support member positioned to support a side portion of a tire assembly positioned on the at least one tire assembly support structure, wherein the side support member includes a first roller and a second roller positioned above the first roller and in line with the first roller; and
a first bottom support member positioned to support a bottom portion of the tire assembly, wherein the first bottom support member comprises a third roller; and
wherein the first roller, the second roller, and the third roller are positioned to allow the tire assembly to rotate around a rotation axis of the tire assembly service cart while supported by the at least one tire assembly support structure.

2. The tire assembly service cart of claim 1 , wherein the first roller and the third roller are positioned substantially perpendicular to each other.

3. The tire assembly service cart of claim 1 , wherein the rotation axis is substantially perpendicular to the side support member.

4. The tire assembly service cart of claim 1 , wherein the at least one tire assembly support structure includes a second bottom support member, wherein the second bottom support member includes a fourth roller, and wherein the second bottom support member is substantially parallel to the first bottom support member.

5. The tire assembly service cart of claim 4 , wherein the first bottom support member and the second bottom support member are connected to the side support member.

6. The tire assembly service cart of claim 4 , wherein the first bottom support member is coupled to the side support member by at least a first structural member that connects to a protruding end or an interior end of the first bottom support member, and wherein the second bottom support member is coupled to the side support member by at least a second structural member that connects to a protruding end or an interior end of the second bottom support member.

7. The tire assembly service cart of claim 4 , wherein the first bottom support member and the second bottom support member are positioned between 15 and 25 inches apart.

8. The tire assembly service cart of claim 4 , wherein the first bottom support member and the second bottom support member are positioned between 36 and 54 inches from a bottom of the tire assembly service cart.

9. The tire assembly service cart of claim 1 , wherein the first roller and the second roller are spaced apart along the side support member to support tire assemblies ranging from 20 to 35 inches in diameter.

10. The tire assembly service cart of claim 1 , wherein the first roller, the second roller, and the third roller include a conveyor roller.

11. The tire assembly service cart of claim 1 , wherein the side support member is tilted from vertical with a lean angle.

12. The tire assembly service cart of claim 11 , wherein the lean angle is greater than or equal to 5 degrees and less than or equal to 20 degrees.

13. The tire assembly service cart of claim 1 , wherein a height of the first bottom support member from a bottom of the tire assembly service cart is adjustable.

14. The tire assembly service cart of claim 1 , wherein the tire assembly service cart comprises two tire assembly support structures symmetrically positioned on opposite sides of the tire assembly service cart.

15. The tire assembly service cart of claim 14 , wherein the two tire assembly support structures are connected by at least one upper member and at least one lower member.

16. The tire assembly service cart of claim 1 , further comprising:
a plurality of vertical lifts positioned to stabilize the tire assembly service cart during servicing of the tire assembly.

17. A tire assembly support structure comprising:
a side support member positioned to support a side of a tire assembly positioned on the tire assembly support structure; and
at least two bottom support members positioned to support the tire assembly from the bottom,
wherein the side support member includes a first roller and a second roller positioned above the first roller and in line with the first roller and the at least two bottom support members include additional rollers that allow the tire assembly to rotate around a rotation axis of the tire assembly support structure, and wherein the rotation axis is substantially perpendicular to the side support member.

18. The tire assembly support structure of claim 17 , wherein the side support member is tilted from vertical at a lean angle that is greater than or equal to 5 degrees and less than or equal to 20 degrees.

19. A tire assembly service cart comprising:
two tire assembly support structures, each tire assembly support structure comprising:
a side support member positioned to support a side of a tire assembly positioned on the tire assembly support structure and including a first side roller and a second side roller positioned above the first side roller and in line with the first side roller; and
at least two bottom support members positioned to support the tire assembly from the bottom, each of the at least two bottom support members having a bottom roller;

an upper member coupled to upper ends of the two tire assembly support structures; and
a lower member coupled to lower ends of the two tire assembly support structures,
wherein the first side roller, the second side roller and the bottom roller of each of the at least two bottom support members are positioned to allow the tire assembly to rotate around a rotation axis of the tire assembly support structure while supported by the tire assembly support structure.

20. The tire assembly service cart of claim 1 , wherein the at least one tire assembly support structure further comprises one or more surfaces having at least one tool mounting point for mounting tools to the at least one tire assembly support structure.
