A NON-PNEUMATIC TIRE HAVING DIVIDED SEGMENTS < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a non-publicly-entering tire, and more particularly, to a non-publicly-added tire in which a tire is divided into a plurality of segments.

BACKGROUND ART [0002] Recently, as a technique developed to replace conventional radial tires, a tread compound deformation technique and a non-infilled (or non-inflation) tire have been mentioned. Among the above-mentioned tires, the tire which develops most rapidly is a non-entry tread. The initial nontraditional tire was developed to respond to a puncture that occurs when a sidewall is impacted by an external impact. The non-airbag tire is a tire designed to compensate for the disadvantages of conventional radial tires through the structure of a tire with no buffering of air and a separate buffer means. However, when the structure of the buffer means is weak, there is a problem that the weight of the vehicle can not be supported and the tire may be damaged.

Hereinafter, conventional prior art will be described. The identification code in the following prior arts is irrelevant to the present invention.

U. S. Patent No. US2014 / 0251518 describes a nontraditional tire having a two spoke structure. It has two spoke structures, so that when one fork is in trouble, it is easy to replace and the spoke structure is in a different direction. However, the tread is in one direction and is vulnerable to lapis lazuli. In addition, if the spoke structure is destroyed, there is a disadvantage that the spoke must be replaced entirely.

EP 1 894 748 describes an NPT in the form of a split spoke structure. This is because the spoke structure is made individually, so that both side portions of the torsion can be easily damaged by receiving the force. The tread has the disadvantage of requiring a single tread to replace the entire tread. US patent US 2009/0211674 describes an NPT that includes a circular spoke structure. If the spoke structure is damaged due to a single module spoke, it is necessary to replace the entire spoke structure, and there is a disadvantage in using the single tread.

[0004] In the document KR 2004-0027984 a tire is described which comprises means for interconnecting an annular band, a web spoke, and a wheel, wherein when the tire is brought into contact with the ground via a cord reinforcement surrounding the annular band and the annular band between the tread and the belt, So that the pressure distribution becomes uniform. However, in the spring tire, there is a problem that the pressure on the ground surface is not uniform and concentrated when the shearing mechanism is absent.
