no. 1 Embodiment approach

[0053] Hereinafter, a tire according to a first embodiment of the tire of the present invention will be described with reference to the drawings. Such as Figure 1A As shown, the tire 10 of the present embodiment has substantially the same cross-sectional shape as a conventional general rubber-made pneumatic tire.

[0054] Such as Figure 1A As shown, the tire 10 includes an annular tire casing 23 (an example of a tire frame), and the tire casing 23 includes a pair of bead portions 12 in contact with the bead seat portion 21 and the rim flange 22 of the rim 20 (see Figure 1B ), the sidewall portion 14 extending outward in the tire radial direction from the bead portion 12, and the tire radially outer end for connecting the sidewall portion 14 on one side and the radially outer side of the sidewall portion 14 on the other side The crown portion 16 (peripheral portion) at the end.

[0055] Here, the tire casing 23 of this embodiment is formed of a single resin material, but ...

Abstract

Disclosed is a tire made from a resin material, particularly a thermoplastic material, and which has reduced air inclusion and increased durability. Air inclusion is reduced and durability is increased in the tire (10) by having an annular tire casing (23) formed from a resin material; a reinforcing cord (26) with a higher rigidity than the resin material which winds helically around the circumference of the tire casing (23) and has at least one portion embedded in the circumference in close adherence to the resin material in a cross-sectional view of the tire casing (23) in the direction of the axle; and a tread (30) provided radially outward from a reinforcing cord layer (28) formed from the reinforcing cord (26).

Description

technical field [0001] The present invention relates to a tire mounted on a rim and a method for manufacturing the tire, and more particularly to a tire at least partially formed of a resin material, especially a thermoplastic material, and a method for manufacturing the tire. Background technique [0002] Conventionally, for vehicles such as passenger cars, pneumatic tires made of rubber, organic fiber materials, steel wire members, and the like are used. [0003] However, there is a limit to the use of recycled rubber after use, and it is incinerated, pulverized, and used as a paving material for roads. [0004] In recent years, resin materials, thermoplastic resins, thermoplastic elastomers, and the like are expected to be used as tire materials from the viewpoints of weight reduction, ease of moldability, and ease of recycling. [0005] For example, Patent Document 1 discloses a pneumatic tire molded using a thermoplastic polymer material. [0006] Patent Document 1: J...
