Abstract

A plurality of connection members 13 connecting an installation disk 11 to a ring-shaped body 12 are formed, in a side view of the non-pneumatic tire, to be axisymmetrical about an imaginary line connecting the respective first ends 21a and 22a of first connection plates 21 and second connection plates 22 to an axial line O and extending in a tire-radial direction. The connection members 13 are arranged in a tire-circumferential direction such that the first connection plates 21 are arranged at a first tire-widthwise position in the tire-circumferential direction and that the second connection plates 22 are arranged at a second tire-widthwise position in the tire-circumferential direction. According to the invention, it is possible to suppress an increase in the weight, hardness, and rolling resistance to secure satisfactory ride qualities and handling qualities, and it is possible to prevent a blowout from occurring.

Claims12

Dependent claims

A non-pneumatic tire comprising:

an installation disk that is mounted on an axle;
a ring-shaped body that surrounds an outer circumferential face of the installation disk;
a plurality of connection members that are arranged in a tire-circumferential direction and connect the installation disk to the ring-shaped body;
and
a tread rubber that is disposed over the entire outer circumferential face of the ring-shaped body,
wherein each connection member has a first connection plate curved so as to protrude in a first direction in the tire-circumferential direction and a second connection plate curved so as to protrude in a second direction that is opposite to the first direction, and each connection member is formed to be axisymmetrical about an imaginary line extending in the tire-radial direction,
the ring-shaped body is divided into a plurality of plate-shaped bodies in the tire-circumferential direction,
a plurality of installation members being provided at ends of the first and second connection plates respectively, the plurality of installation members capable of moving relative to each other with changes in a tire-circumferential length.
