Abstract
Provided is a non-pneumatic tire in which buckling can be prevented without a weight increase, the non-pneumatic tire including a spoke structure. The spoke structure is obtained by circumferentially arranging spokes intermittently at intervals and coupling together annular cylindrical outer member and cylindrical inner. The spoke structure is joined to an inner peripheral side of a tread ring. At least some of a plurality of spaces formed between two spokes adjacent to each other in the tire circumferential direction have an air-containing structure.
Claims15
A non-pneumatic tire comprising:
- a spoke structure joined to an inner peripheral side of a tread ring, the spoke structure including a cylindrical outer member, a cylindrical inner member spaced coaxially from the cylindrical outer member and spokes arranged intermittently at intervals in a tire circumferential direction so as to couple the cylindrical outer member and the cylindrical inner member to each other, the spoke structure having a first side opposite a second side in a tire width direction, the cylindrical outer member having an outer peripheral side joined to the inner peripheral side of the tread ring;
- and
- a plurality of spaces each formed between adjacent two of the spokes in the tire circumferential direction and extending continuously from the first side to the second side and having a first opening on the first side with an opening size which is substantially the same as an opening size of a second opening on the second side, the spaces being structured to have further divided spaces in the tire radial direction, at least some of the further divided spaces located outermost in the tire radial direction having an air-containing structure;
- wherein the cylindrical outer member, the cylindrical inner member and the spokes are formed of resin.
A non-pneumatic tire comprising:
- a spoke structure joined to an inner peripheral side of a tread ring, the spoke structure including a single cylindrical outer member having a width substantially the same as the tread ring, a single cylindrical inner member having a width substantially the same as the tread ring spaced coaxially from the cylindrical outer member and a plurality of spokes extending in a tire width direction and arranged intermittently at intervals in a tire circumferential direction, and at least two wall members extending in the tire circumferential direction and arranged in the tire width direction to define a plurality of zones extending in the tire circumferential direction, so as to couple the cylindrical outer member and the cylindrical inner member to each other, the cylindrical outer member having an outer peripheral side joined to the inner peripheral side of the tread ring;
- a plurality of spaces each formed between adjacent two of the spokes in the tire circumferential direction and between the at least two wall members;
- and
- an air-containing structure provided in the space between the at least two walls.
