Abstract

A non-pneumatic tire is provided. The non-pneumatic tire includes an outer annular portion, an inner annular portion, and a load bearing ring positioned between the outer annular portion and the inner annular portion. The load bearing ring includes at least one reinforcing layer, and each of the at least one reinforcing layers includes one or more strips of multi angle tension control reinforcement (MATCR) material.

Claims (25)

1 . A non-pneumatic tire comprising:

an outer annular portion;

an inner annular portion; and

a load bearing ring positioned between the outer annular portion and the inner annular portion;

wherein the load bearing ring comprises at least one reinforcing layer; and

wherein each of the at least one reinforcing layers comprises one or more strips of multi angle tension control reinforcement (MATCR) material.

2 . The tire of claim 1 , wherein the MATCR material comprises a woven construction including a warp wire and a weft wire.

3 . The tire of claim 2 , wherein the warp wire provides circumferential strength to the composite.

4 . The tire of claim 2 , wherein the weft wire deforms the warp wire radially, providing tension support and shear modulus in both the radial and lateral directions.

5 . The tire of claim 2 , wherein the weft wire provides lateral stiffness.

6 . The tire of claim 2 , wherein the warp wire and the weft wire independently have a tensile strength of between 0.1 and 50,000 Newtons.

7 . The tire of claim 2 , wherein the weft wire alternates between going over and under each consecutive warp wire.

8 . The tire of claim 2 , wherein the weft wire alternates between going over and under every two consecutive warp wires.

9 . The tire of claim 2 , wherein the weft wire passes through twisted warp wires.

10 . The tire of claim 2 , wherein the warp wire and weft wire independently include up to 40 ends per inch.

11 . The tire of claim 2 , wherein the warp wire and weft wire independently include a material selected from the group consisting of cotton, nylon, polyester, aramid, rayon, steel or other strengthening materials, composites, and combinations thereof.

12 . The tire of claim 1 , wherein the at least one reinforcing layer is coated with rubber, other polymer composite materials, or a combination thereof.

13 . The tire of claim 1 , wherein the at least one reinforcing layer comprises between 2 and 10 reinforcing layers.

14 . The tire of claim 1 , wherein the load bearing ring further comprises an outer matrix material between the at least one reinforcing layer and the outer annular portion.

15 . The tire of claim 1 , wherein the load bearing ring further comprises an inner matrix material between the at least one reinforcing layer and the inner annular portion.

16 . The tire of claim 1 , wherein the outer annular portion includes a tread pattern.

17 . The tire of claim 16 , wherein the outer annular portion includes one or more sub-surface layers radially positioned beneath the tread pattern.

18 . The tire of claim 1 , wherein the inner annular portion is in direct contact with a wheel hub.

19 . The tire of claim 1 , wherein the tire includes a radially inner sidewall and a radially outer sidewall.

20 . The tire of claim 1 , wherein the tire further comprises spokes between the load bearing ring and the inner annular portion.
