Description

TECHNICAL FIELD [0001] The present invention relates to an inner liner reinforcement member, an inner liner reinforcement member,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner liner reinforcing member and an air inlet tire including the inner liner reinforcing member and more particularly to an inner liner inner reinforcing member An inner liner reinforcement member including a lower reinforcement member attached in a tire circumferential direction to prevent damage to an inner liner caused when a tire puncture is generated and to prevent excessive sidewall supporter from being deformed and a pneumatic tire including the inner liner reinforcement member will be.

1, the general pneumatic tire 10 includes an inner liner 11 constituting an inner circumference of a tire, a carcass 12 laminated on the outer circumferential surface of the inner liner 11, A full cap ply 14 which is laminated on the outer circumferential surface of the belt 13 and which fixes the belt 13 and an outer circumferential surface 14 of the full cap ply 14, And a bead portion 16 for allowing the tire to be mounted on the rim as the end of the sidewall. Pneumatic tires of this type have a tendency to puncture a rubber layer between steel cords when a sharp foreign matter (17) such as a nail or a bangle pierces the tire, so that air pressure leaks to this portion suddenly, The air pressure inside the tire drops below a certain level, and as a result, the function of the tire is lost.

Generally, when a puncture occurs on a road, it is often run at a low speed to a nearby repair shop. At this time, if the vehicle runs under a low air pressure condition, the inner liner of the tire may be damaged and the carcass cord may be damaged due to compression and / or wear caused by the load of the vehicle. In addition, if the tire is not replaced at the repair shop and only the puncture-generated portion of the tread is repaired and internal confirmation is not made, a Sidewall Burst may be caused at a high-speed traveling thereafter. According to statistics, more than 50% of the tires with sidewall bursts were caused by internal carcass damage caused by the inner liner damage during the first puncture. Also, about 70% of the punctured tires were damaged by the inner liner inside the tire, so that the tire could not be reused.

2 is a photograph showing a damaged inner liner inner side of a tire according to the prior art. Referring to FIG. 2, the specific portion where the inner liner is damaged is a flexible zone of the inner liner where the inner shoulder portion of the tire contacts the rim portion when the tire is folded in the run flat state.

In order to solve these problems, various techniques for preparing tire punctures have been developed. For example, run flat tires and seal tires have been developed. Among them, the run flat tire is a tire that can run at a certain distance while supporting the load of the vehicle even when there is no air pressure of the tire due to a puncture recently.

The run flat tire is divided into two types. The run flat tire is classified into two types: the strength of the sidewall that is the basic skeleton of the tire is increased, so that even if the air leaks and the air pressure is weakened, the outer shape of the tire is maintained A sidewall reinforcement type and a support ring type in which a support ring is provided inside a tire to allow the tire to continue to run under the support of the support ring when the air pressure is weakened.

The run flat tire of the sidewall reinforcement type requires no additional equipment, but can be used easily. However, a large amount of rubber is used in the sidewall portion, which lowers the ride quality and affects the fuel consumption and the balance between left and right. On the other hand, the run-flat tire of the support ring type can maintain the same ride feeling as that of the existing tire, but a separate support ring has to be inserted and installed.

SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-described problems, and it is an object of the present invention to provide an upper liner of a vehicle, which comprises an upper reinforcement member attached to an inner surface of an inner liner of a belt at a tire circumferential direction, An inner liner reinforcement member including a reinforcing member to prevent leakage of air inside a tire and to operate a tire at an expected wear level even after repairing a puncture.

One aspect of the present invention for achieving the above object is an inner liner reinforcing member composed of an upper reinforcing member and a lower reinforcing member, wherein the upper reinforcing member is attached to the inner liner inner surface of the belt- And the lower reinforcement member is attached to the inner surface of the inner liner on the tire rim check line side in the tire circumferential direction.

According to another aspect of the present invention, there is provided a tire comprising: an inner liner constituting an inner circumference of a tire; a carcass stacked on an outer circumferential surface of the inner liner; a belt laminated on an outer circumferential surface of the carcass; A pneumatic tire comprising a full cap ply which is laminated and fixes the belt, a tread layer which is laminated on the outer circumferential surface of the full cap ply and contacts the ground, and a bead portion which allows the tire to be mounted on the rim as an end of the sidewall, An upper reinforcement member is attached to the inner surface of the belt-side end inner liner in a tire circumferential direction, and a lower reinforcement member is attached to an inner surface of the inner liner of the tire rim check line side in the tire circumferential direction, The present invention relates to a pneumatic tire that is supported in tight contact with a liner.

The inner liner reinforcement member according to the present invention is attached to both sides of the flexible portion connected to the rim check line from the end of the belt layer and has a structure in which the inner liner reinforcement member is brought into close contact with the inner surface of the tire, thereby preventing damage to the inner liner It is possible to prevent the sidewall flexible portion from being excessively deformed. Therefore, it is possible to prevent air leakage inside the tire and to prevent a vehicle accident caused by secondary sidewall damage. In addition, since the structure of the inner liner reinforcing member and the shape attached to the inner liner are various, it can be applied to tires having different sizes, and it is also economical to replace only a part of the worn inner liner reinforcing member.
