Abstract
A non-pneumatic tire includes a lower ring having a first diameter, an upper ring having a second diameter greater than the first diameter, and a plurality of closed geometric shapes connected to the lower ring. The non-pneumatic tire further includes a plurality of spokes extending from each closed geometric shape to the upper ring. Each of the plurality of spokes includes a first linear segment connected to one of the plurality of closed geometric shapes and extending in a first direction, and a second linear segment connected to the upper ring and extending in a second direction different from the first direction.
Claims19
A non-pneumatic tire comprising:
- a plurality of hoops including at least a first hoop and a second hoop, each of the plurality of hoops having opposing faces lying in opposing planes perpendicular to a rotational axis of the non-pneumatic tire, wherein each of the plurality of hoops includes:
- a lower ring having a first diameter;
- an upper ring having a second diameter greater than the first diameter, the upper ring being coaxial with the lower ring;
- a support structure extending between the lower ring and the upper ring, wherein the support structure includes:
- a plurality of closed geometric shapes connected to the lower ring, and
- a plurality of spokes extending from each closed geometric shape to the upper ring, each of the plurality of spokes including a first linear segment connected to one of the plurality of closed geometric shapes and extending in a first direction and a second linear segment connected to the upper ring and extending in a second direction different from the first direction,
- wherein the plurality of spokes extending from each closed geometric shape includes a first spoke and a second spoke, and
- wherein the first linear segment of the first spoke is parallel to the first linear segment of the second spoke.

A method of making a non-pneumatic tire, the method comprising:
- providing a first hoop having a first face and a second face, the first hoop including:
- a first lower ring extending laterally from the first face to the second face;
- a first upper ring extending laterally from the first face to the second face, the first upper ring being coaxial with the first lower ring;
- a first plurality of closed geometric shapes connected to the first lower ring and extending laterally from the first face to the second face, and
- a first plurality of spokes extending from the first plurality of closed geometric shapes to the first upper ring, each of the first plurality of spokes including a first linear segment connected to one of the first plurality of closed geometric shapes and extending in a first direction and a second linear segment connected to the upper ring and extending in a second direction different from the first direction,
- wherein the plurality of spokes extending from each closed geometric shape includes a first spoke and a second spoke, and
- wherein the first linear segment of the first spoke is parallel to the first linear segment of the second spoke;
- providing a second hoop having a first face and a second face, the second hoop including:
- a second lower ring extending laterally from the first face to the second face;
- a second upper ring extending laterally from the first face to the second face, the second upper ring being coaxial with the second lower ring;
- a second plurality of closed geometric shapes connected to the second lower ring and extending laterally from the first face to the second face, and
- a second plurality of spokes extending from the second plurality of closed geometric shapes to the second upper ring, the second plurality of spokes having the same geometry as the first plurality of spokes;
- and
- aligning the first face of the first hoop with the first face of the second hoop such that the first plurality of spokes extend in a direction opposite to the second plurality of spokes.
