Non-pneumatic tire with geodesic ply and bead
A non-pneumatic tire is described which includes a ground contacting annular tread portion, a shear band, and a reinforcement structure positioned radially inward of the tread. The reinforcement structure is formed from a plurality of strips, wherein each strip has a first end located radially outward of the shear band and a second end secured to a bead, wherein the plurality of strips do not extend completely across the annular tread portion.
1. A non-pneumatic tire comprising
a ground contacting annular tread portion;
a shear band; and
a reinforcement structure positioned radially inward of the tread, said reinforcement structure being formed from a plurality of strips, wherein each strip has a first end located radially outward of the shear band and a second end secured to a bead, wherein the plurality of strips do not extend completely across the annular tread portion.
2. The non-pneumatic tire of claim 1 wherein the reinforcement structure is a layer of ply.
3. The non-pneumatic tire of claim 1 wherein the reinforcement structure is a plurality of strips of material.
4. The non-pneumatic tire of claim 3 wherein the strips are reinforced with one or more parallel reinforcements.
5. The non-pneumatic tire of claim 1 wherein the reinforcement structure is angled inwardly.
6. The non-pneumatic tire of claim 1 wherein the strips are oriented in the radial direction forming ply spokes.
7. The non-pneumatic tire of claim 1 wherein the non-pneumatic tire is mounted on a standard rim.
8. The non-pneumatic tire of claim 1 wherein the non-pneumatic tire is mounted on a rim, wherein the rim is axially adjustable.
9. The structurally supported non-pneumatic tire of claim 4 wherein the angle alpha is in the range of −20 to +20 degrees.
10. A non-pneumatic tire comprising
a ground contacting annular tread portion;
a shear band; and
a reinforcement structure positioned radially inward of the tread, said reinforcement structure being formed from a plurality of strips, wherein each strip has a first end located between the shear band and a second end secured to a bead, wherein the plurality of strips do not extend completely across the annular tread portion.
