Description

자동차용 공기입 타이어 {Pneumatic vehicle tire} Pneumatic vehicle tire

본 발명은, 자동차용 공기입 타이어에 관한 것이다.The present invention relates to pneumatic tires for automobiles.

일반적으로, 인너라이너, 카카스, 벨트 및 트레드부로 구성되어 있는 종래의 타이어는 고속 주행시 회전 저항이 급격히 증가하고, 어느 한계를 초과하면 일그러진 타이어의 복원 현상이 급격히 저하되어 스탠딩웨이브 현상이 발생하는 결점이 있다. 또한 이러한 종래의 타이어는 여러 가지의 원인에 의하여 그 내부의 공기가 누출될 경우 타이어의 주저앉음 현상 정도가 커서 차량 사고의 원인이 되기도 한다. 이러한 결점을 해소하기 위하여 종래에는 벨트 부위의 강성을 높이거나 고무의 량을 줄여 고속 주행시 받는 타이어의 저항을 줄여보고자 하였으나 벨트 부위의 강성을 높이면 타이어의 중량이 커지고 제조 비용이 상승하며, 고무의 량을 줄이면 타이어의 수명이 감축되고 내구성이 불리한 결점이 있었다.In general, a conventional tire composed of an inner liner, a carcass, a belt and a tread portion has a rapid increase in rotational resistance at high speeds, and when a certain limit is exceeded, the restoration phenomenon of the distorted tire rapidly decreases and a standing wave phenomenon occurs. There is this. In addition, such a conventional tire is a cause of a vehicle accident because the degree of swelling of the tire is large when the air inside thereof leaks due to various causes. In order to solve this drawback, conventionally, attempt to reduce the resistance of tires received at high speed by increasing the rigidity of the belt part or reducing the amount of rubber, but increasing the rigidity of the belt part increases the weight of the tire and increases the manufacturing cost, and the amount of rubber This reduces the service life of the tire and has disadvantages in durability.

이에, 본 발명은, 타이어의 원주상의 원형 형상 유지 능력을 향상시켜 회전 저항을 감소시키고, 스탠딩웨이브 현상을 감소시키며, 공기누출에 의한 주저앉음 현상을 감소시켜 사고의 발생을 감소시킬 수 있도록, 트레드부에 원주방향으로 보강선을 설치하여서 된 타이어를 제공하기 위한 것인 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Accordingly, the present invention, to improve the ability to maintain the circular shape of the tire to reduce the rotational resistance, to reduce the standing wave phenomenon, to reduce the occurrence of accidents by reducing the phenomenon of sitting down due to air leakage, To provide a tire by installing a reinforcement line in the circumferential direction of the tread portion, the present invention will be described with reference to the accompanying drawings as follows.

인너라이너(1)와 카카스(2), 벨트(3) 및 트레드(4)로 구성된 자동차용 공기입 타이어에 있어서, 본 발명은 트레드(4)에 원주 방향으로 보강선(5)을 삽입 설치하는 것을 특징으로 한다. In the pneumatic tire for automobiles composed of the inner liner (1) and the carcass (2), the belt (3) and the tread (4), the present invention inserts and installs the reinforcement line (5) in the circumferential direction on the tread (4). Characterized in that.

트레드(4)에 보강선(5)을 설치함에 있어서는, 블록형 타이어의 경우 블록(44)과 이에 원주 방향으로 인접한 블록(44) 사이에 설치한 타이바(45)에 설치하는 것이 바람직하다.In providing the reinforcement line 5 in the tread 4, in the case of the block-type tire, it is preferable to install in the tie bar 45 provided between the block 44 and the block 44 adjacent to the circumferential direction.

블록형 타이어의 경우, 고속 주행에 있어서의 타이어의 회전 저항을 줄이고 스탠딩웨이브 현상을 감소시키기 위해 블록(44)과 이에 원주 방향으로 인접한 다른 블록(44) 사이에 타이바(45)를 형성시키는 것이 보통이다. 이와 같은 타이바(45)는 블록과 블록(44) 사이를 결합하여 블록간의 유동을 줄이고 블록의 강성을 향상시키는 바, 본 발명은 상술한 보강선(5)을 설치함에 있어서 이를 타이바(45) 내부에 이를 설치함으로서 블록의 유동을 현저히 감소시킬 수 있게 하는 것이 바람직하다. In the case of block-type tires, forming a tie bar 45 between the block 44 and another block 44 adjacent in the circumferential direction in order to reduce the rolling resistance of the tire at high speed and reduce the standing wave phenomenon. is average. Such a tie bar 45 is coupled between the block and the block 44 to reduce the flow between the blocks and improve the rigidity of the block, the present invention in installing the reinforcement line 5 described above tie bar 45 It is desirable to install it inside the shell to significantly reduce the flow of the block.

트레드(4)에 보강선(5)을 설치함에 있어서, 보강선(5)의 개수는 하나 이상의 임의의 다수로 형성시킬 수 있으나, 좌우 하나씩 두 개를 설치하는 것이 바람직하다.In installing the reinforcing wires 5 in the tread 4, the number of the reinforcing wires 5 may be formed in any number of one or more, but it is preferable to provide two ones left and right.

보강선(5)은 그 단면이 사각형이거나 원형으로 된 하나의 금속선으로 형성시킬 수 있으며, 다수의 가는 코드를 합체하여 형성시킬 수도 있다.The reinforcement line 5 may be formed by a single metal wire having a rectangular or circular cross section, and may be formed by combining a plurality of thin cords.

보강선(5)의 재질은 철인 것이 바람직하나, 알루미늄, 초경합금, 세라믹 및 강화플라스틱 중에서 선택될 수도 있다. The material of the reinforcing wire 5 is preferably iron, but may be selected from aluminum, cemented carbide, ceramic, and reinforced plastic.

이와 같이 구성된 본 발명은 타이어의 회전 저항을 약 10%이상 줄일 수 있으며, 스탠딩웨이브 발생 속도 또한 약 20%이상 지연시키어 그 효능을 향상시킬 수 있다. 뿐만 아니라, 본 발명의 타이어는 원주상 원형 형상 유지능력이 개선되어 빗길에서 발생되는 수막 현상을 억제할 수 있는 효과를 가져 올 수 있다. 뿐만 아니라 타이어로부터 공기가 누출 될 경우에 있어서의 타이어의 급격한 주저앉음 현상을 막아 차량의 사고를 감소시킬 수 있다. The present invention configured as described above can reduce the rotational resistance of the tire by about 10% or more, and also delay the generation of the standing wave by about 20% or more to improve its efficacy. In addition, the tire of the present invention may have an effect of suppressing the water film phenomenon generated in the rain by improving the cylindrical circular shape holding ability. In addition, it is possible to reduce the accident of the vehicle by preventing the tire from drowning when the air leaks from the tire.

이와 같은 본 발명의 효과를 측정하기 위하여, 본 출원인 회사의 제품인 타이어(상품 코드; 185/65R14)와 이에 본 발명을 실시한 두 개의 타이어에 대하여 그 성능을 시험한 결과는 다음과 같다. 아래의 시험에 사용된 본 발명의 실시예1은 위의 타이어에 직경mm의 2개 스틸 보강선을 설치한 실시예이고, 실시예2는 같은 직경의 스틸 보강선을 3개 설치한 실시예이다.In order to measure the effects of the present invention, the results of testing the performance of the tire (product code; 185 / 65R14), which is a product of the present applicant, and the two tires according to the present invention are as follows.
