Abstract
Official abstract text for this publication.
A green tire includes a plurality of sheets of green rubber having a substantially circular shape, wherein each sheet of green rubber includes an upper ring and a lower ring, and each sheet of green rubber further includes a plurality of spoke portions extending from the upper ring to the lower ring. The green tire further includes a plurality of reinforcements. Each reinforcement is disposed between adjacent sheets of green rubber. At least one reinforcement is sandwiched between the upper rings of adjacent sheets of green rubber, and at least one reinforcement is sandwiched between the spoke portions of adjacent sheets of green rubber.
First claim
Opening claim text (preview).
What is claimed is: 1. A green tire comprising: a plurality of sheets of green rubber having a substantially circular shape, wherein each sheet of green rubber includes an upper ring and a lower ring, and wherein each sheet of green rubber further includes a plurality of spoke portions extending from the upper ring to the lower ring; and a plurality of reinforcements, each reinforcement being disposed between adjacent sheets of green rubber, the reinforcements being cords of material, wherein at least one reinforcement is sandwiched between the upper rings of adjacent sheets of green rubber, and wherein at least one reinforcement is sandwiched between the spoke portions of adjacent sheets of green rubber. 2. The green tire of claim 1 , wherein each sheet of green rubber is constructed of a plurality of different green rubber compounds. 3. The green tire of claim 1 , wherein at least one of the spoke portions has a geometry that varies along an axial direction of the green tire. 4. The green tire of claim 1 , wherein each sheet of green rubber has between 10 and 40 spoke portions. 5. A green tire comprising: a plurality of sheets of green rubber having a substantially circular shape, wherein each sheet of green rubber includes an upper ring and a lower ring, and wherein each sheet of green rubber further includes a plurality of spoke portions extending from the upper ring to the lower ring; and a plurality of reinforcements, each reinforcement being disposed between adjacent sheets of green rubber, the reinforcements being cords of material, wherein each reinforcement includes at least one upper ring and a plurality of spoke reinforcements extending from the at least one upper ring, the plurality of spoke reinforcements being spaced circumferentially from one another, wherein at least one reinforcement is sandwiched between the upper rings of adjacent sheets of green rubber, and wherein at least one reinforcement is sandwiched between the lower rings of adjacent sheets of green rubber. 6. The green tire of claim 5 , wherein at least one of the plurality of sheets of green rubber includes a tire sidewall portion, and wherein the green tire is configured to be a pneumatic tire. 7. The green tire of claim 5 , wherein the green tire is configured to be a non-pneumatic tire. 8. The green tire of claim 1 , wherein each reinforcement includes at least one upper ring and at least one lower ring spaced apart from and below the at least one upper ring.
