Abstract

A structurally supported tire includes a ground contacting annular tread portion, an annular shear band and at least one spoke disk connected to the shear band, wherein the spoke disk has at least two spokes, wherein each spoke extends between an outer ring and an inner ring, wherein one of the spokes extends from the outer ring to the inner ring in a curved manner. The second spoke extends from the outer ring to the inner ring in a straight manner.

First claim

What is claimed:

1. A structurally supported non-pneumatic tire comprising
a ground contacting annular tread portion;
a shear band, wherein the shear band includes a first and a second reinforced elastomer layer separated by a shear matrix; and at least two spoke disks connected to the shear band, wherein each spoke disk are spaced apart from each other, wherein each spoke disk has a first and a second spoke, wherein each spoke extends between an outer ring and an inner ring, wherein the first spoke extends from the outer ring to the inner ring in a curved manner and is joined to the second spoke forming a junction, wherein each spoke disk has an axial thickness less than an axial thickness of the tire, wherein the first spoke and the second spoke each have a portion that buckles under load in the same angular direction.

2. The structurally supported non-pneumatic tire of claim 1 wherein the second spoke extends from the outer ring to the inner ring in a straight manner.

3. The structurally supported non-pneumatic tire of claim 1 wherein the spring rate of the spoke disk is greater than the spring rate of the shear band.

4. The structurally supported non-pneumatic tire of claim 1 wherein an axial thickness of the spoke disk is greater than a thickness of the spoke.

5. The structurally supported non-pneumatic tire of claim 1 wherein a ratio of a spoke axial width W 2 to a spoke thickness t 2 , W 2 /t 2 is in the range of 8 to 12.

6. The structurally supported non-pneumatic tire of claim 1 wherein a ratio of a spoke axial width W 2 to a spoke thickness t 2 , W 2 /t 2 is in the range of 9 to 22.

7. The structurally supported non-pneumatic tire of claim 1 wherein each spoke has a length L 2 from the outer ring to the junction, and a length L 1 from the junction to the inner ring, wherein the ratio of L 1 /L 2 of each spoke is in the range of 0.2 to 5.

8. The structurally supported non-pneumatic tire of claim 1 wherein each spoke has a length L 2 from the outer ring to the junction, and a length L 1 from the junction to the inner ring, wherein the ratio of L 1 /L 2 of each spoke is in the range of 0.5 to 2.

9. A non-pneumatic tire comprising
a ground contacting annular tread portion;
a shear band, wherein the shear band includes a first and a second reinforced elastomer layer separated by a shear matrix; and at least two spoke disks connected to the shear band, wherein each spoke disk are spaced apart from each other, wherein each spoke disk has a first and a second spoke, wherein each spoke extends between an outer ring and an inner ring, wherein the first spoke extends from the outer ring to the inner ring in a curved manner and is joined to the second spoke forming a junction, wherein each spoke disk has an axial thickness less than an axial thickness of the tire, wherein the first spoke and the second spoke each have a portion that bends under load in the same direction with respect to each other.
