Description
Technical field
The present invention relates to for installing to the tire of wheel rim, and at least some of by setting particularly to wherein tire casing
The tire that fat material is formed.
Background technology
The pneumatic tire becoming known for the vehicles such as car is made up of rubber, organic fibrous material and steel beam column etc..
In recent years, from lightweight, easily shaping, the angle easily reclaimed, use resin material, particularly thermoplasticity are being studied
Plastics and thermoplastic elastomer (TPE) etc., as tire material.
Such as, patent documentation 1 (Japanese Patent Application Laid-Open (JP-A) 2003-104008 publication) and patent documentation 2
(JP-A H03-143701 publication) describes a kind of pneumatic tire, and this pneumatic tire is by thermoplastic macromolecule material, especially
It is that thermoplastic poly esters elastomer is formed.
Compared with traditional rubber ratch tire, use the tire of the macromolecular material (resin material) with thermoplastic characteristics more
Easily manufacture, and cost is lower.
In the case of using thermoplastic macromolecule material to manufacture tire, realization is needed to have compared with traditional rubber ratch tire
The performance (requirements of tire characteristics) of profit, the most also realizing manufacturing efficiency at low cost increases.
But, when tire is only formed by the uniform thermoplastic resin not comprising reinforcement members such as casingply, root
According to JP-A 2003-104008 publication, compare with traditional rubber ratch tire, it is difficult to realize equal compression resistance, internal pressure resistance
And rigidity.But, according to JP-A H03-143701 publication, it is wound with benefit with continuous helical shape along tire circumferential direction
The strengthening course of strong cord, is arranged at the outer surface radially of the tire bottom the tyre surface of tire body (tyre framework body), and tire
