Abstract

본 발명은 타이어에 관한 것으로, 특히, 육각기둥의 비드코어를 가지며 그 외방을 스틸채퍼로 보강하여서 된 비드부를 가진 타이어에 관한 것이다. 이러한 종래의 타이어에 있어서는, 육각기둥으로 된 비드코어의 모서리와 스틸채퍼 사이의 카카스가 절단되는 일이 있었던 바, 본 발명은 카카스가 절단되는 일을 방지하기 위해, 스틸채퍼에 분할부를 두되 분할부를 비드코어의 모서리 대응부에 위치시킴으로서, 분할부를 채우는 고무층이 비드코어의 모서리가 가하는 응력을 수용할 수 있게 하여 카카스의 절단을 방지할 수 있게 한 것임.TECHNICAL FIELD The present invention relates to a tire, and more particularly, to a tire having a bead core having a hexagonal pillar and having a bead portion formed by reinforcing the outside with a steel chafer. In such a conventional tire, the carcass between the edge of the bead core made of a hexagonal column and the steel chafer has been cut, and according to the present invention, in order to prevent the carcass being cut, the split portion is formed in the steel chaper. By arranging the head portion of the bead core at the corner corresponding part of the bead core, the rubber layer filling the partition can accommodate the stress applied by the edge of the bead core to prevent the carcass from being cut.

본 발명은 타이어에 관한 것으로, 특히, 육각기둥의 비드코어를 가지며, 그 외방에 스틸채퍼를 설치하여서 된 비드부를 가진 타이어에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire, and more particularly, to a tire having a bead core having a hexagonal pillar and having a bead portion provided with a steel chafer outside thereof.

이러한 종래의 타이어에 있어서는, 스틸채퍼가 도마의 기능을 하고 육각 기둥으로 된 비드코어의 모서리가 도끼의 기능을 하여, 비드코어의 모서리와 스틸채퍼 사이의 카카스가 절단되는 일이 있었던 것이다.In such a conventional tire, the steel chafer functions as a cutting board, and the corner of the bead core made of a hexagonal column functions as an ax, and the carcass between the edge of the bead core and the steel chaper may be cut.

이에 본 발명은, 카카스가 절단되는 일을 방지하기 위해 스틸채퍼의 비드코어 모서리 대응부에 분할부를 형성시켜, 분할부가 고무층으로 채워지게 함으로서, 분할부를 채우는 고무층이 비드코어의 모서리가 가하는 응력을 수용할 수 있게 하여 카카스의 절단을 방지할 수 있게 하였는 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.
Accordingly, the present invention, by forming a portion in the bead core edge corresponding portion of the steel chaper to prevent the carcass is cut, so that the portion is filled with a rubber layer, the rubber layer filling the portion is applied to the edge of the bead core It was to be able to accommodate the stress to prevent the cutting of the carcass, this invention will be described with reference to the accompanying drawings as follows.

육각기둥의 비드코어(1)를 가지며 비드코어(1)를 감싼 카카스(2)의 외방을 스틸채퍼(3)로 보강하여서 된 비드부를 가진 타이어에 있어서, 본 발명은 스틸채퍼(3)에 분할부(4)를 두되 분할부(4)를 비드코어(1)의 모서리 대응부에 위치시킴으로 서, 분할부(4)를 채우는 고무층이 비드코어(1)의 모서리가 가하는 응력을 수용할 수 있게 구성시킨다.In a tire having a bead core having a hexagonal bead core and having a bead portion reinforcing the outer side of the carcass 2 wrapping the bead core 1 with a steel chaper 3, the present invention relates to a steel chaper 3; By placing the divider 4 but placing the divider 4 at the corner corresponding portion of the bead core 1, the rubber layer filling the divider 4 can accommodate the stress exerted by the edge of the bead core 1. Configure it to

이와 같이 구성된 본 발명은, 스틸채퍼(3)에 형성된 분할부(4)가 고무층으로 채워지게 마련이며, 그리하여 비드코어(1)의 모서리부가 가하는 응력을 분할부(4)의 고무층이 수용할 수 있게 되어 이 부위에 있어서의 카카스(2) 절단 염려를 감소시킬 수 있는 효과가 있다.










According to the present invention configured as described above, the divided portion 4 formed in the steel chafer 3 is filled with a rubber layer, so that the rubber layer of the divided portion 4 can receive the stress applied to the edge portion of the bead core 1. There is an effect that can reduce the carcass (2) cleavage concerns in this area.
