Abstract

A non-pneumatic tire is provided with: a mounting body (11) that is mounted on a vehicle axle; a ring component (14) that is provided with an inner cylindrical body (12) that is fitted onto the outside of the mounting body (11), and an outer cylindrical body (13) that encircles the inner cylindrical body (12) from the outside in the radial direction of the tire; and a plurality of linking components (15) that are lined up along the circumferential direction of the tire between the inner cylindrical body (12) and the outer cylindrical body (13), and that link together these two cylindrical bodies (12, 13) such that they can be elastically displaced relative to each other, wherein the ring component (14) and the plurality of linking components (15) are formed integrally as a single unit.

Claims

1. A non-pneumatic tire comprising:

a mounting body that is mounted on a vehicle axle;

a ring component that is provided with an inner cylindrical body that is fitted onto the outside of the mounting body, and an outer cylindrical body that encircles the inner cylindrical body from the outside in the radial direction of the tire; and

a plurality of linking components that are lined up along the circumferential direction of the tire between the inner cylindrical body and the outer cylindrical body, and that link together these two cylindrical bodies such that they can be elastically displaced relative to each other, wherein

the ring component and the plurality of linking components are formed integrally as a single unit.

2. The non-pneumatic tire according to claim 1, wherein

the linking components are provided with a first elastic linking plate and a second elastic linking plate that link together the two cylindrical bodies, and

one end portion of each first elastic linking plate that is connected to the outer cylindrical body is positioned further to one side in the tire circumferential direction than another end portion of the first elastic linking plate that is connected to the inner cylindrical body, and

one end portion of each second elastic linking plate that is connected to the outer cylindrical body is positioned further to the other side in the tire circumferential direction than another end portion of the second elastic linking plate that is connected to the inner cylindrical body, and

a plurality of the first elastic linking plates are lined up along the tire circumferential direction at one position in the tire transverse direction, while a plurality of the second elastic linking plates are lined up along the tire circumferential direction at another position in the tire transverse direction that is different from the one position in the tire transverse direction.

3. The non-pneumatic tire according to claim 2, wherein

the ring component is separated into a one-side separate ring component that is positioned on one side in the tire transverse direction, and an other-side separate ring component that is positioned on the other side in the tire transverse direction, and

the one-side separate ring component is formed integrally as a single unit with the first elastic linking plates, and

the other-side separate ring component is formed integrally as a single unit with the second elastic linking plates.

4. The non-pneumatic tire according to claim 3, wherein the one-side separate ring component and the first elastic linking plate are formed integrally as a single unit by casting or extrusion molding, and the other-side separate ring component and the second elastic linking plate are also are formed integrally as a single unit by casting or extrusion molding.

5. The non-pneumatic tire according to claim 2, wherein the respective one end portions of the first elastic linking plate and the second elastic linking plate in a single linking component are joined to the same position in the tire circumferential direction, but to mutually different positions in the tire transverse direction on an inner circumferential surface of the outer cylindrical body, and

the linking components are formed such that, in a tire side view in which the tire is viewed from tire transverse direction, they have line symmetry relative to a imaginary line that extends in the tire radial direction and passes through the respective one end portions.
