Non-pneumatic tire with reinforcing member having plate wire structure
Disclosed herein is a non-pneumatic tire with a reinforcing member. The non-pneumatic tire includes a tread part which comes into contact with the ground, a rim part which is coupled to an axle, an outer annular band part which forms an interface with an inner surface of the tread part, an inner annular band part which forms an interface with the rim part, a spoke part which is disposed between the outer annular band part and the inner annular band part and functions as a support, a connector which connects spokes of the spoke part to each other, and a reinforcing member which has a plate wire structure. The non-pneumatic tire can effectively and sufficiently withstand the weight of a vehicle. Further, the performance of the tire is balanced with respect to the contact area, the displacement extent and the resistance to rolling.
1. A non-pneumatic tire, comprising:
a tread part coming into contact with a ground surface;
a rim part coupled to an axle;
an outer annular band part forming an interface with an inner surface of the tread part;
an inner annular band part forming an interface with the rim part;
a spoke part disposed between the outer annular band part and the inner annular band part, the spoke part functioning as a support;
a connector connecting spokes of the spoke part to each other; and
a reinforcing member,
wherein the reinforcing member comprises a plate wire wound a plurality of times spirally, and the plate wire has a thin band shape.
2. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member is arranged in the tread part in a circumferential direction of the tread part.
3. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member is arranged in the outer annular band part in a circumferential direction of the outer annular band part.
4. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member is arranged in the inner annular band part in a circumferential direction of the inner annular band part.
5. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member comprises a multi-layered structure, wherein each layer comprises a plate wire wound a plurality of times spirally, the plate wire having a thin band shape.
6. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member is made of any one selected from the group consisting of metal, steel, carbon, aramid and glass fiber or a compound of the metal, the steel, the carbon, the aramid and the glass fiber.
7. The non-pneumatic tire as set forth in claim 1 , wherein the reinforcing member is configured such that a height thereof is greater than a width thereof or less than the width, and each of four angled corners of the reinforcing member is rounded with a predetermined curvature radius.
