Abstract

A tire and wheel assembly includes a tire, a circular hub member for securing to a rotatable axle of a vehicle, the rim piece having a first annular ring flange for engaging the tire, a rim piece for engaging the hub member, a second annular ring flange for engaging the tire, and a plurality of cylindrical shafts for each axially engaging the first annular ring flange at one axial end of each of the shafts and the second annular ring flange at another opposite axial end of each of the shafts.

First claim

What is claimed:

1. A nonpneumatic wheel assembly comprising:
an annular spoke structure formed of a plurality of loops and having an interior void and a first and second lateral end;
an annular rim piece mounted within the interior void of the annular spoke structure and extending the entire axial width of the annular spoke structure,

the annular rim piece having a first ring flange connected to a first lateral end of the annular rim piece for engaging a first lateral end of the annular spoke structure;
a second ring flange for engaging a second lateral end of the annular spoke structure; and
a plurality of cylindrical shafts, wherein each cylindrical shaft is positioned in a respective loop of the annular spoke structure, and wherein a first end of each cylindrical shaft is secured to the first ring flange and a second end is secured to the second ring flange.

2. The tire and wheel assembly as set forth in claim 1 wherein the first ring flange has first circular openings arranged circumferentially about the first ring flange.

3. The tire and wheel assembly as set forth in claim 2 wherein the second ring flange has second circular openings arrayed circumferentially about the second ring flange.

4. The tire and wheel assembly as set forth in claim 3 wherein each of the first circular openings of the rim piece is axially aligned with a corresponding first bore hole of one of the shafts.

5. The tire and wheel assembly as set forth in claim 4 wherein each of the shafts has a radially outer surface for engaging corresponding loops of the tire.

6. The tire and wheel assembly as set forth in claim 1 wherein each shaft engages an inner radial surface of a corresponding loop of the tire.

7. The wheel assembly as set forth in claim 1 wherein the rim piece and ring flanges are constructed of a metal.

8. The wheel assembly as set forth in claim 1 wherein the rim piece and ring flanges are constructed of a polymer.
