Description

펑크 대비용 공기입 타이어Pneumatic tires for puncture

본 발명은 사이드월부의 강성을 보강하여 타이어 펑크 시에도 일정한 속도로 주행을 이룰 수 있게 한 것으로서, 더욱 상세하게는 사이드월부의 보강으로 인한 승차감의 저하를 방지하고 제조공정수를 단축하며 제조 원가를 절감시킬 수 있도록 한 펑크 대비용 공기입 타이어에 관한 것이다.The present invention is to reinforce the rigidity of the side wall to achieve a constant speed even when the tire puncture, more specifically to prevent the deterioration of the ride feeling due to the reinforcement of the side wall, to reduce the number of manufacturing process and reduce the manufacturing cost It relates to a pneumatic tire for puncture preparation which can be saved.

일반적으로 공기입 타이어는 타이어의 내부에 충전되는 공기압에 의하여 차량의 무게를 지탱하는 것으로 타이어의 내부에 공기압이 존재하지 않게 되면 타이어의 내부면이 림에 밀착되어 주행을 이룰 수 없게 된다.In general, the pneumatic tire supports the weight of the vehicle by the air pressure charged in the tire, and when there is no air pressure inside the tire, the inner surface of the tire is in close contact with the rim, thereby preventing driving.

이와 같은 상태에서 무리하게 주행을 하게 되면 타이어의 사이드월부가 파손되어 펑크를 수리한다 하더라도 더이상 타이어로써 기능을 발휘하지 못하게 되는 것이다.If you drive excessively in this state, even if the sidewall of the tire is damaged and repair the puncture will no longer function as a tire.

이와 같은 문제점을 해결하기 위한 종래의 수단으로써 사이드월부의 강성을 증대시켜 타이어의 내부에 공기압이 존재하지 않는 경우 타이어의 사이드월부가 차량의 무게를 지탱할 수 있게 하는 미국 특허 5511599호 제공된 바는 있다.As a conventional means for solving such a problem, US Patent 5511599 has been provided to increase the rigidity of the sidewall portion so that the sidewall portion of the tire can support the weight of the vehicle when there is no air pressure inside the tire.

그러나 상기 선행 기술은 타이어의 골격인 카카스를 다수 겹으로 형성시키고 사이드월부에 위치하는 카카스와 카카스 사이의 공간 내에 고경도의 보강고무를 삽입시켜 구성되는 것이다.However, the prior art is formed by forming a plurality of carcasses, the skeleton of the tire, and inserting a high hardness reinforcement rubber into the space between the carcasses and the carcasses located in the sidewalls.

이와 같이 사이드월부의 강성을 증대시키기 위하여 카카스를 다수 겹으로 형성시키고 카카스의 사이사이에 보강고무를 삽입시키는 기술은 그 제조에 많은 어려움이 있고 많은 공정이 요구되어 제품의 생산 원가가 크게 상승하게 되는 결점이 있는 것이다.In order to increase the rigidity of the sidewalls, a technique of forming a plurality of carcasses and inserting reinforcement rubbers between the carcasses has a lot of difficulties in manufacturing and requires a large number of processes, thus greatly increasing the production cost of the product. There is a flaw to be made.

또한 사이드월부의 두께가 필요 이상으로 증가되어 타이어의 전체 중량을 상승시켜 연비성능을 저하시킴은 물론 승차감도 현저하게 저하시키는 문제점이 있는 것이다.In addition, the thickness of the side wall portion is increased more than necessary to increase the overall weight of the tire to reduce the fuel efficiency performance, as well as to significantly reduce the riding comfort.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 사이드월부의 보강 구조를 개선하여 사이드월부의 보강으로 인한 승차감의 저하를 방지하고, 제조공정수를 단축하며 제조 원가를 절감시킬 수 있도록 한 펑크 대비용 공기입 타이어를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the present invention is to improve the reinforcement structure of the side wall portion to prevent the deterioration of the ride comfort due to the reinforcement of the side wall portion, can reduce the number of manufacturing process and reduce the manufacturing cost The purpose is to provide a pneumatic tire for puncture.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 본 발명은 비드부와 사이드월부 및 트래드부로 구성되는 공기입 타이어에 있어서, 상기 트래드부의 벨트에지부에서부터 비드필러 중간 부위까지 다수 겹의 코드지를 적층설치시키고, 적층된 보강코드지의 내부에 보강벨트층을 설치시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. The present invention is a pneumatic tire consisting of a bead portion, a side wall portion and a tread portion, a plurality of layers of cord paper from the belt edge portion of the tread portion to the middle portion of the bead filler is laminated, reinforcement belt layer inside the laminated reinforcement cord paper It is characterized by being configured to install.

첨부된 도면 도 1 은 본 발명에 따른 공기입 타이어를 발췌 도시한 단면도이다.1 is a cross-sectional view showing an extract of a pneumatic tire according to the present invention.

도 1 에 도시된 바와 같이, 본 발명은 비드부(3)와 사이드월부(2) 및 트래드부(1)로 구성되는 공기입 타이어에 있어서, 상기 사이드월부(2)에 다수 겹의 보강 코드지(4)를 적층설치시키고, 적층된 보강코드지(5)의 내부에 보강벨트층(5)을 설치시켜 사이드월부(2)의 강성을 증대시킬 수 있도록 구성되는 것으로, 상기 보강벨트층(5)은 트래드 내부에 설치되는 벨트와 동일하게 경사를 이루는 스틸코드의 고무층을 토핑시켜 구성되며, 이와 같은 벨트층을 복수겹으로 겹쳐 설치시킨다. 이와 같이 보강벨트층(5)을 복수겹으로 겹쳐 설치시키는 경우에는 각 벨트층의 내부에 배열되는 스틸코드가 반대의 방향을 이루도록 한다.As shown in FIG. 1, the present invention is a pneumatic tire composed of a bead portion 3, a side wall portion 2, and a tread portion 1, wherein a plurality of layers of reinforcement cord paper are provided on the side wall portion 2. (4) is laminated, and the reinforcing belt layer (5) is provided inside the laminated reinforcing cord paper (5) to increase the rigidity of the side wall portion (2), the reinforcing belt layer (5) ) Is configured by topping the rubber layer of the steel cord to be inclined in the same manner as the belt installed in the tread, and to install such a belt layer in a plurality of layers. When the reinforcing belt layer 5 is provided in a plurality of layers in this manner, the steel cords arranged inside the belt layers form the opposite directions.

그리고 상기 보강코드지(4)는 벨트에지부(11)의 하단에서부터 비드필러(31)의 중간 부위까지 형성시키며, 코드지(4)는 벨트에지부(11)의 하단에서부터 시작하여 비드필러(31)의 중간 부위에서 턴업하여 다시 벨트하단부로 적층되고, 벨트 하단 부위에서 턴다운되어 비드필러(31)의 중간 부위까지 적층되는 동작을 반복하여 사이드월부(2)의 강성을 보강시키는 것이다.The reinforcing cord paper 4 is formed from the lower end of the belt edge portion 11 to the middle portion of the bead filler 31, and the cord paper 4 starts from the lower end of the belt edge portion 11, and the bead filler ( 31 is turned up at the middle portion of the belt and is laminated to the lower end of the belt, and the operation is repeated at the bottom of the belt to be laminated down to the middle portion of the bead filler 31 to reinforce the rigidity of the side wall portion 2.

이때 보강코드지(4)의 상단부는 벨트에지부(11)의 하단에 삽입설치되며, 삽입되는 깊이는 5 내지 40mm의 범위 내에서 삽입설치한다.At this time, the upper end of the reinforcing cord paper 4 is inserted into the lower end of the belt edge portion 11, the insertion depth is inserted into the installation range of 5 to 40mm.

또한 보강코드지(4)의 끝단은 비드필러(31) 전체길이의 1/3지점보다 높고 1/2지점보다 낮은 위치에 설치시킨다.In addition, the end of the reinforcing cord paper 4 is installed at a position higher than 1/3 of the total length of the bead filler 31 and lower than 1/2.

그리고 상기 보강코드지(4)는 사이드월부(2)의 최대 폭을 이루는 부위에서 3 내지 5층을 이루도록 한다.And the reinforcing cord paper (4) is to form three to five layers at the site forming the maximum width of the side wall (2).

이와 같은 본 발명은 카카스(21)의 코드 배열이 레디알구조 또는 바이어스 구조로 이루어지는 것에 상관없이 공히 사용될 수 있으며, 모든 코드 재질의 카카스에도 적용 실시할 수 있는 것이다.The present invention as described above can be used regardless of whether the cord arrangement of the carcass 21 is a radial structure or a bias structure, and can be applied to the carcass of all cord materials.

이와 같이 구성되는 본 발명은 타이어의 펑크로 인하여 타이어 내부의 공기가 누출되면서 벨트층(10)의 저면이 림의 표면에 접촉되는 과정에서 보강코드지(4)와 보강벨트층(5)이 사이드월부(2)를 지지하여 찌그러짐을 방지함에 따라 타이어의 높이가 더이상 낮아지지 않게 된다.In the present invention configured as described above, the reinforcing cord paper 4 and the reinforcing belt layer 5 are in the process of contacting the bottom surface of the belt layer 10 with the surface of the rim as air inside the tire leaks due to the puncture of the tire. The height of the tire is no longer lowered by supporting the lunar part 2 to prevent distortion.

이에 의해 사이드월부(2)의 꺾임 없이 일정한 속도 하에서 계속적인 주행을 이룰 수 있게 되는 것이다.Thereby, it is possible to achieve continuous running under a constant speed without bending the side wall portion (2).

본 발명은 전술한 실시 예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

이상에서와 같이 본 발명에 따르면 사이드월의 두께를 두껍게 하지 않고서도 트래드부를 지지할 수 있어 승차감의 저하와 비드부의 이탈을 방지하며, 적은 비용과 단순한 공정으로 타이어를 제조할 수 있어 원가를 절감하고 생산성을 증대시킬 수 있는 효과가 있는 것이다.As described above, according to the present invention, it is possible to support the tread portion without increasing the thickness of the sidewall, thereby preventing deterioration of ride comfort and detachment of the bead portion, and manufacturing a tire with a low cost and a simple process, thereby reducing the cost. There is an effect that can increase the productivity.
