차량용 공기입 타이어{Pneumatic vehicle tire}Pneumatic vehicle tire

본 발명은 차량용 공기입 타이어에 관한 것으로, 특히 트레드 저부에 설치되는 벨트층의 개량에 관한 것이다. TECHNICAL FIELD The present invention relates to a pneumatic tire for a vehicle, and more particularly to an improvement of a belt layer provided at the bottom of a tread.

일반적인 차량용 타이어는 노면과 직접 접촉하는 트레드부와, 트레드부 양단에 설치되어 노면으로 부터의 충격을 흡수하는 사이드월부와, 사이드월부 하단에 설치되어 자동차의 림에 장착되는 비드부로 구성되며, 타이어를 구성하는 각 부분들은 각각의 공정에 의해 반제품으로 완성되어 성형공정을 거치면서 그린타이어로 형태를 갖춘뒤 가류과정을 거쳐 타이어로 제조된다.A general vehicle tire is composed of a tread part directly contacting the road surface, a sidewall part installed at both ends of the tread part to absorb shock from the road surface, and a bead part installed at the bottom of the sidewall part and mounted on the rim of the vehicle. Each part is made of semi-finished product by each process, is formed into green tires through molding process, and then made into tire through vulcanization process.

트레드부는 노면과 직접접촉하는 부분으로서 내마모성과 내컷팅성이 양호해야 함은 물론 발열이 적어야하고 충분한 충격흡수력의 물리적 성질이 요구된다. 이에 따라, 트레드부 저부에 보강벨트가 설치되어 트레드부의 강도를 높여주고, 트레드부에서 받은 충격 및 트레드에 발생한 크랙(crack) 등이 카카스에 전달되는 것을 방지하게 된다.As the tread part is in direct contact with the road surface, the wear resistance and cutting resistance should be good, the heat generation should be low, and the physical properties of sufficient shock absorbing force are required. Accordingly, a reinforcing belt is installed at the bottom of the tread portion to increase the strength of the tread portion, and prevents the shock received from the tread portion and cracks generated in the tread from being transmitted to the carcass.

이러한 역할을 수행하기 위해 종래의 보강벨트는 스틸코드가 일정하게 배열되고 그 위에 고무 토핑이 이루어지며, 이러한 벨트는 타이어의 규격 또는 사양에 따라 일정크기와 각도로 절단되고 복수매가 중첩되어 완성된 보강벨트로 제작된다.In order to perform this role, the conventional reinforcing belt is a steel cord is constantly arranged and a rubber topping is made thereon, such a belt is cut to a certain size and angle according to the tire specifications or specifications and a plurality of overlapping reinforcement completed It is made of a belt.

일반적으로 벨트는 2장이 사용되며, 타이어에서, 뼈대라고 할수 있는 카카스를 보호하는 역할과 함께, 접지(Grip)력 및 핸들링(Handling) 성능 및 승차감에 큰 영향을 주는 구성요소이다. 그러나 상기와 같은 물리적 요건을 충족시키기 위해서는 벨트의 중량이 너무 큰 단점이 있있다.In general, two belts are used, and in a tire, it is a component that has a great influence on grip force, handling performance, and ride comfort, along with a role of protecting a carcass, which can be called a skeleton. However, there is a disadvantage that the weight of the belt is too large to satisfy the above physical requirements.

즉, 타이어의 벨트층의 물리적 성능을 크게 떨어뜨리지 아니하면서 타이어를 경량화시킬 수 있는 기술이 필요한 것이다.In other words, there is a need for a technology that can reduce the weight of the tire without significantly reducing the physical performance of the belt layer of the tire.

이에 본 발명은 벨트들이 원주방향으로 간격을 갖도록 분리된 타이어를 제공하여 상기 경량화 문제를 해결하려 한다.Accordingly, the present invention is to provide a tire that is separated so that the belts are spaced in the circumferential direction to solve the weight reduction problem.

본 발명에 따르면 벨트의 물리적 성능을 크게 떨어뜨리지 아니하면서 타이어를 경량화시켜 연비 향상 등의 효과를 얻을 수 있다.According to the present invention, it is possible to reduce the physical performance of the belt without significantly reducing the weight of the tire to achieve effects such as improved fuel economy.

본 발명은 트레드(1)와 사이드월(2) 및 비드부(3)로 구성되며, 트레드 저부에 벨트층(4)이 설치되고, 상기 벨트층은 1벨트(41)와 2벨트(42)를 포함하는 것에 있어서, 상기 벨트들이 원주방향으로 간격을 갖도록 분리된 것을 특징으로 한다.The present invention is composed of a tread (1), sidewall (2) and the bead portion (3), the belt layer 4 is provided at the bottom of the tread, the belt layer is a belt 41 and two belts 42 In including, the belt is characterized in that separated to have a gap in the circumferential direction.

첫 번째 실시예로서, 도 2에 도시된 바와 같이, 본 발명은 1벨트가 중심선(L)을 기준으로 벨트폭의 5~10%의 간격(a)을 갖도록 분리된 구성을 제공한다.As a first embodiment, as shown in Figure 2, the present invention provides a configuration in which one belt has a spacing (a) of 5 to 10% of the belt width with respect to the center line (L).

상기 상기 벨트폭의 5~10%의 간격(a)은 50mm~100mm인 것이 바람직하다.It is preferable that the interval (a) of 5 to 10% of the belt width is 50 mm to 100 mm.

본 발명의 두 번째 실시예로서, 도 3에 도시된 바와 같이, 2벨트(42)는 중심선(L)을 기준으로 벨트폭의 5~10%만큼 간격(b)을 갖도록 2개의 벨트로 분리되고, 1벨트(41)는 벨트폭의 5~10%만큼의 간격(b)을 갖도록 3개의 벨트로 분리되고, 각 벨트의 분리된 부분들이 인접 벨트에의해 메꿔지도록 교호로 배치되는 구성을 제공한다.As a second embodiment of the present invention, as shown in Figure 3, the two belts 42 are separated into two belts so as to have a spacing b by 5 to 10% of the belt width relative to the center line L and 1 belt 41 is divided into three belts with a spacing b of 5-10% of the belt width, and alternately arranged so that the separate portions of each belt are filled by adjacent belts. .

이때, 1벨트 및 2벨트의 각 분리된 간격(b)은 50mm~100mm이 이 바람직하고, 1벨트의 분리된 간격부분과 중심선(L)과의 거리(d)는 150-200mm인 것이 바람직하다.At this time, each of the separated gap (b) of the 1 belt and 2 belt is preferably 50mm ~ 100mm, the distance (d) between the separated interval portion of the one belt and the center line (L) is preferably 150-200mm. .

즉, 본 발명은 벨트의 경량화를 위해서, 최대 폭은 동일하게 유지하면서 실제로 사용되는 벨트의 폭은 줄어드는 효과를 가진다. That is, the present invention has the effect of reducing the width of the belt actually used while keeping the maximum width the same for reducing the weight of the belt.
