Pneumatic tire, and method of manufacturing same

Abstract

The present invention provides a pneumatic tire in which a mechanical fastener member for attaching an object is installed on the inner surface of the pneumatic tire, the mechanical fastener member being joined to a tire inner peripheral surface with very high joint strength, and a method of manufacturing the pneumatic tire. In the pneumatic tire according to the present invention, one of two members of the mechanical fastener member which is separable into the two members is fixed on the tire inner surface while protruding on the tire inner cavity side, the mechanical fastener member having a fixing strength of 0.1 to 100 (N / mm2). According to the method of manufacturing the pneumatic tire of the present invention, the mechanical fastener member is placed on the inner surface of a green tire prior to vulcanized molding, the fastener member protruding on the tire inner cavity side, a space formed between around the tip of the protruding portion of the mechanical fastener member and the green tire inner surface around the mechanical fastener member is loaded with a collar member filling the space and subjected to a vulcanized molding step, and then the collar is removed.

Description

technical field [0001] The present invention relates to a pneumatic tire and its manufacturing method. [0002] More specifically, it relates to a pneumatic tire provided with a mechanical fastener member for mounting an object on the inner surface of the pneumatic tire, and particularly relates to joining the mechanical fastener to the inner peripheral surface of the tire with very high joint strength. A pneumatic tire and a method for manufacturing the same. Background technique [0003] In recent years, various studies have been made on the technique of installing objects having various functions on the inner peripheral surface of a pneumatic tire or the like. [0004] For example, an attachment method has been proposed in which a tire such as a high-frequency identification tag is attached to a raw tire inner liner or the like using so-called hook and loop fasteners such as hook and loop fasteners. For tags, chips, etc., refer to Patent Document 1. [0005] In additio...

AI Technical Summary

Problems solved by technology

[0007] However, in the case of hook-and-loop fasteners, since the inner peripheral surface of the pneumatic tire is a curved annular surface, etc., the fastening state of each fastening component in the hook-and-loop fastener is not ideal. Parts of the hook-and-loop fastener may float in the center, etc., and the magnitude of the fastening force obtained may be uneven, that is, the position within the tire is uneven, the tire is uneven, etc.

Therefore, the desired snapping force cannot be obtained

In addition, under the condition of high temperature, long-term repeated deformation and compression caused by high-speed rotation will cause local physical deterioration of the tire, and with the aggravation of the local physical deterioration, the overall safety of the hook-and-loop fastener The fastening force will deteriorate or decrease over time, so it is difficult to maintain the desired fastening force for a long time

[0008] Furthermore, hook-and-loop fasteners are ideal in that surface joints can be achieved even if there is a slight deviation in position during installation, but on the other hand, if the functional object to be installed is a measuring machine, etc., it is required The mounting position is more precise i.e. high precision, at this point there are also some functional objects that are not suitable for mounting with hook and loop fasteners
