Abstract
Abstract To provide a non-pneumatic tire, including a spoke structure, which can be easily mounted on a rim of a wheel. In addition, to provide a non-pneumatic tire whose durability is improved by suppressing the buckling of a spoke structure. [Solving Means] Provided is a non-pneumatic tire including a spoke structure ( 5 ) and a tread ring ( 11 ). The spoke structure ( 5 ) includes a cylindrical outer member ( 2 ) and a cylindrical inner member ( 3 ) which are concentrically arranged, and which are connected to each other with a plurality of fins ( 4, 4 ′) arranged in between at intervals in the circumferential direction. The tread ring ( 11 ) is fitted onto the outer periphery of the spoke structure ( 5 ). In the pneumatic tire, the spoke structure ( 5 ) is divided in the tire circumferential direction into at least two circumferential-direction separate structures ( 511, 521, 531 ).

A non-pneumatic tire comprising: a spoke structure including a cylindrical outer member and a cylindrical inner member which are concentrically arranged, and which are connected to each other with a plurality of fins arranged in between at intervals in the circumferential direction; and a tread ring fitted onto the outer periphery of the spoke structure, wherein the spoke structure is divided in the tire circumferential direction into at least two circumferential-direction separate structures.
Claim 2
Dependent Claim
75 words
1 . A non-pneumatic tire comprising: a spoke structure including a cylindrical outer member and a cylindrical inner member which are concentrically arranged, and which are connected to each other with a plurality of fins arranged in between at intervals in the circumferential direction; and a tread ring fitted onto the outer periphery of the spoke structure, wherein the spoke structure is divided in the tire circumferential direction into at least two circumferential-direction separate structures.
Claim 3
Dependent Claim
22 words
2 . The non-pneumatic tire according to claim 1 , wherein the number of the circumferential-direction separate structures is 2 to 8.
Claim 4
Dependent Claim
54 words
3 . The non-pneumatic tire according to claim 1 , wherein the spoke structure is divided in the tire width direction into three width-direction separate structures, and the fins of one of each adjacent two of the width-direction separate structures are displaced in the circumferential direction relative to the fins of the other one.
Claim 5
Dependent Claim
56 words
4 . The non-pneumatic tire according to claim 3 , wherein the fins of each adjacent two of the width-direction separate structures have the same arrangement pitch in the circumferential direction, and the amount of displacement of the fins between each adjacent two of the width-direction separate structures is 0.4 to 0.6 times the arrangement pitch.
Claim 6
Dependent Claim
47 words
5 . The non-pneumatic tire according to claim 3 , wherein among the three width-direction separate structures, the arrangement pitch of the fins of the width-direction separate structure in the center is made smaller than that of the fins of the width-direction separate structures on both sides.
Claim 7
Dependent Claim
41 words
6 . The non-pneumatic tire according to claim 3 , wherein among the three width-direction separate structures, the width of the width-direction separate structure in the center is smaller than that of each of the width-direction separate structures on both sides.
Claim 8
Dependent Claim
47 words
7 . The non-pneumatic tire according to claim 3 , wherein among the three width-direction separate structures, the thickness of each fin of the width-direction separate structure in the center is smaller than that of each fin of each of the width-direction separate structures on both sides.
Claim 9
Dependent Claim
47 words
8 . The non-pneumatic tire according to claim 6 , wherein among the three width-direction separate structures, the thickness of each fin of the width-direction separate structure in the center is smaller than that of each fin of each of the width-direction separate structures on both sides.
