비드부를 개량한 자동차용 타이어{Vehicle tire improved bead member}Vehicle tire improved bead member

본 발명은 자동차용 타이어에 관한 것으로 특히 비드부를 개량하여서 된 자동차용 타이어에 관한 것이다.The present invention relates to an automobile tire, and more particularly to an automobile tire by improving a bead portion.

타이어는, 카카스를 골조로 하고, 카카스 중앙부에 벨트층을 형성시키며, 벨트층 위에 트레드고무층을 설치하고, 트레드고무층의 양측에 사이드월고무층을 설치하며, 사이드월고무층의 양단에 비드부를 설치하여 구성시키되, 비드부는, 다수의 강선을 겹쳐 형성시켜서되는 비드코어에 비드필러를 설치하고, 비드코어와 비드필러를 카카스로 감싸는 구성을 기본 요소로 하여 형성된다. 그런데, 이와 같은 종래의 타이어에 있어서는 비드코어를 감싸는 카카스가 타이어의 내압에 견디지 못하고 비드코어로부터 미끄러져 비드부 파손을 초래하는 위험이 있었다. The tire is framed with a carcass, a belt layer is formed at the center of the carcass, a tread rubber layer is provided on the belt layer, side wall rubber layers are provided on both sides of the tread rubber layer, and bead portions are provided at both ends of the side wall rubber layer. The bead portion is formed by providing a bead filler on a bead core formed by overlapping a plurality of steel wires, and wrapping the bead core and the bead filler with a carcass as a basic element. By the way, in such a conventional tire, there was a risk that the carcass surrounding the bead core could not withstand the internal pressure of the tire and slipped from the bead core to cause bead breakage.

그리하여, 비드코어를 감싸는 카카스 턴엎(Turn up) 단부를 카카스에 접합되게 함으로써 카카스 단부의 풀림을 방지하게 하려는 타이어(특허출원 제1020017007967호)가 제공된 바 있다. 그러나, 이러한 정도의 기술로는 장기간 나쁜 조건하에서 운행되는 타이어에 강한 내압이 걸릴 경우에 있어서의 풀림방지 효과를 기대하기에는 부족한 결점이 있었다. 그 후, 비드코어를 감싸는 카카스 단부를 비드코어에 압박시키는 압박코어를 설치하여 압박코어가 카카스 단부를 비드코어에 압박하게 하여서되는 비드부를 가지는 타이어게 제공된 바 있다(특허출원 제1020060058268). 그러나, 이러한 타이어는 카카스 풀림의 방지효과가 큰 효과가 있기는 하나 제조가 곤란한 결점이 있다.Thus, there has been provided a tire (patent application No. 1020017007967) intended to prevent loosening of the carcass end by allowing the carcass turn up end surrounding the bead core to be joined to the carcass. However, such a degree of technology has a shortcoming in that it is insufficient to expect an anti-loosening effect when a strong internal pressure is applied to a tire that is operated under bad conditions for a long time. Thereafter, there has been provided a tire having a bead portion in which a pressing core for pressing the carcass end surrounding the bead core against the bead core is provided so that the pressing core presses the carcass end against the bead core (Patent Application No. 1020060058268). However, such a tire has a drawback that is difficult to manufacture although it has a great effect of preventing carcass loosening.

이에 본 발명은, 비드코어를 감싸는 카카스가 설혹 나쁜 조건하에서 장시간 운행되며 타이어에 강한 내압이 걸린다 하더라도 카카스가 비드코어로부터 미끄러져 풀리는 일이 없게 하면서도 제조가 간편한 타이어를 제공하여야 한다는 과제를 해결하고자 한다.Therefore, the present invention solves the problem of providing a tire that is easy to manufacture while the carcass surrounding the bead core is operated for a long time under bad conditions and the carcass is not slipped off from the bead core even if a strong internal pressure is applied to the tire. I would like to.

위와 같은 과제를 해결하기 위하여 본 발명은 비드코어를 형성시킴에 있어서, 다수의 강선을 겹쳐 형성시킨 강선링(wire ring)뭉치의 외주에 강선을 나사식으로 감아 비드코어를 형성시킴으로써, 비드코어를 감싸는 카카스의 코드가 나사식으로 감겨진 강선의 사이 사이의 홈에 끼워져 비드부의 코어와 카카스코드의 접촉 면적이 확대되게 하여서 되는 타이어를 제공한다.In order to solve the above problems, the present invention in forming a bead core, by forming a bead core by winding the steel wire around the outer periphery of the wire ring bundle formed by overlapping a plurality of steel wire, The wrapping carcass cord is fitted into a groove between the threaded steel wires to provide a tire in which the contact area between the core of the bead portion and the carcass cord is enlarged.

타이어를 제조함에 있어서는, 카카스를 골조로 하고, 카카스 중앙부에 벨트층을 형성시키며, 벨트층 위에 트레드고무층을 설치하고, 트레드고무층의 양측에 사이드월고무층을 설치하며, 사이드월고무층의 양단에 비드부를 설치하여 구성시키되, 비드부는, 다수의 강선을 겹쳐 형성시켜서되는 비드코어에 비드필러를 설치하고, 비드코어와 비드필러를 카카스로 감싸는 구성을 기본 요소로 하여 형성되는 그린 타이어를 제조하고, 이러한 그린 타이어를 가황 금형에 넣고 그린타이어의 내부에 브라더를 설치하고 브라더를 팽창시킴으로써 그린타이어가 금형의 형상에 따라 성형되게 하는 바, 본 발명은, In manufacturing a tire, the carcass is framed, a belt layer is formed in the center of the carcass, a tread rubber layer is provided on the belt layer, side wall rubber layers are provided on both sides of the tread rubber layer, and both sides of the side wall rubber layer are provided. The bead part is installed and configured, but the bead part installs a bead filler in a bead core formed by overlapping a plurality of steel wires, and manufactures a green tire formed based on a configuration in which the bead core and the bead filler are wrapped in a carcass. By inserting the green tire into the vulcanizing mold and installing the brother inside the green tire and inflating the brother, the green tire is molded according to the shape of the mold.

비드코어를 형성시킴에 있어서, 다수의 강선을 겹쳐 형성시킨 강선링(wire ring)뭉치의 외주에 강선을 나사식으로 감아 비드코어를 형성시키었으므로, 위와 같은 가황 공정에서 브라더의 팽창력으로 카카스가 당겨지게되고 그리하면 카카스를 구성하는 각개의 코드가 상기 나사식으로 감긴 강선의 사이 사이에 끼워져 들어가게 되므로, 결국 카카스의 코드와 비드코어의 접합면적이 확대되며, 따라서, 비드코어와 카카스코드의 마찰력이 강화되어 카카스의 풀림 현상이 감소되고 이러한 풀림현상의 감소는 비드부 파손으로 인한 사고를 감소시키게 되는 효과가 있다.In forming the bead core, the bead core was formed by winding the steel wire around the outer circumference of the wire ring bundle formed by stacking a plurality of steel wires. And each cord constituting the carcass is sandwiched between the threaded steel wires, thereby increasing the joint area between the carcass cord and the bead core, and thus, the bead core and car The frictional force of the cascade is enhanced to reduce the loosening of the carcass, and the reduction of the loosening effect reduces the accidents caused by the bead breakage.

카카스를 골조로 하고, 카카스 중앙부에 벨트층이 형성되며, 벨트층 위에 트레드고무층이 설치되고, 트레드고무층의 양측에 사이드월고무층이 설치되며, 사이 드월고무층의 양단에 비드부가 설치되고, 비드부는, 다수의 강선이 겹쳐 형성된 강선링(wire ring)으로 되는 비드코어에 비드필러를 설치하고, 비드코어와 비드필러를 카카스로 감싸 구성되는 자동차용 타이어에 있어서, 본 발명은 비드코어가 다수의 강선링(wire ring)을 합쳐 형성시킨 강선링뭉치와 강선링뭉치 외주를 나사식으로 감싸는 강선(6)으로 구성된 것을 특징으로 하는 비드부를 개량한 자동차용 타이어를 제공하는 바 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Framed with a carcass, a belt layer is formed in the center of the carcass, a tread rubber layer is installed on the belt layer, sidewall rubber layers are provided on both sides of the tread rubber layer, and bead portions are provided at both ends of the sidewall rubber layer. [0002] The present invention relates to a vehicle tire in which a bead filler is provided on a bead core formed of a wire ring formed by overlapping a plurality of steel wires, and the bead core and the bead filler are wrapped in a carcass. The present invention provides a tire for an automobile having improved bead parts, comprising: a steel wire ring bundle formed by joining wire rings of the wire ring and a steel wire 6 that wraps around the outer circumference of the steel wire ring bundle. Referring to the accompanying drawings as follows.
