본 발명은 트레드 아래에 다수층으로 적층되는 벨트의 강성을 부분적으로 불균일하게 만들어 차량이 시속 90㎞ 이상의 고속으로 빗길 노면을 주행할때 타이어와 노면 사이의 물이 순간적으로 단단한 판자 같아 되어 슬립을 일으키는, 하이드로 플래닝 현상을 방지하게 된 공기입 타이어의 벨트의 제조방법에 관한 것이다.The present invention partially uneven the stiffness of the belt stacked in multiple layers under the tread, causing water between the tire and the road to become slippery when the vehicle travels on rainy roads at high speeds of more than 90 km / h, causing slippage. The present invention relates to a belt manufacturing method of a pneumatic tire that prevents hydroplaning.
종래에는, 공기입 타이어의 하이드로 플래닝 현상을 방지하기 위하여, 타이어 패턴의 종그루브 및 횡그루브의 구조개선 방법과 그루브 벽면의 경사각도 변경, 트래드 블록내 사이프(Sipe)의 형성등을 주로 사용하였으나, 상기의 방법이 적용된 공기입 타이어는 NG%(Net Gross Ratio : 트레드의 접지면과 트레드 그루브 접지면과의 관계)가 낮아, 타이어의 내마모성 및 핸들링 성능, 견인성 등 타이어 제반성능이 오히려 나빠졌었다.Conventionally, in order to prevent hydroplaning of pneumatic tires, the method of structural improvement of longitudinal grooves and lateral grooves of tire patterns, the change of the inclination angle of groove walls, the formation of sipes in the tread block, etc. are mainly used. The pneumatic tire to which the above method is applied has a low NG% (relationship between the tread ground plane and the tread groove ground plane), and the overall tire performance, such as abrasion resistance, handling performance, and traction, of the tire is deteriorated.
본 발명은 이처럼 하이드로 플래닝 현상을 억제하기 위해 타이어의 외형을 변형시킬 때, 공기입 타이어의 제반특성이 나빠지는 구조상의 문제점을 해소하기 위해서, 필요시에만 수로 역할을 하는 배출홈이 트레드면에 형성되고 정상주행 조건에서는 배출홈이 형성되지 않게 하여, 타이어 제특성의 저하없이도 안티-하이드로 플래닝 성능을 향상하게 된 특징이 있으며, 이하 첨부도면에 의거 본 발명에 따른 안티-하이드로 플래닝 성능이 개선되는 공기입 타이어용 벨트의 제조방법과 그 타이어에 관해 상세히 설명하면 다음과 같다.In order to solve the structural problem that the overall characteristics of the pneumatic tire deteriorate when the outer shape of the tire is deformed in order to suppress the hydroplaning phenomenon as described above, an exhaust groove serving as a water channel is formed on the tread surface only when necessary. And the exhaust groove is not formed in the normal driving conditions, thereby improving anti-hydro planning performance without deterioration of tire characteristics, and air having improved anti-hydro planning performance according to the present invention according to the accompanying drawings. Hereinafter, a method of manufacturing a belt for a wear tire and a tire thereof will be described in detail.
본 발명에서는 트레드(4) 아래에 다수층으로 적층되는 벨트(1)를 제조함에 있어서, 상기 벨트(1) 중앙부(L)의 강성을 양측부(S)의 강성과 상이하게 제조함이 특징이며, 상기 방법에 따라 제조된 벨트(1)로 공기입 타이어를 구성한다.In the present invention, when manufacturing the belt (1) laminated in multiple layers under the tread (4), the stiffness of the central portion (L) of the belt (1) is characterized in that it is different from the stiffness of both sides (S) , And constitutes a pneumatic tire with a belt (1) manufactured according to the above method.
첨부도면 제1도와 제2도는 본 발명에 따른 공기입 타이어용 벨트의 한쪽 고무층을 절개시켜 본 사시도와 상기 밸트 코드가 스틸 코드인 경우의 사시도로서, 벨트(1)의 중앙부(L)폭은 트레드 전폭(T)의 50% 이내로 적용하며, 상기 벨트(1)의 중앙부에 배열되는 스틸코드(2)부분의 단면적은 정상상태 단면적의 10∼90% 사이로 제조한다. 또한, 코드의 단면적을 부분적으로 상이하게 적용하는 대신 코드의 재질을 상이하게 적용하며, 영률(Young's Moduls : 강성)이 다른 부분이 중앙부(L)에 나타날 수 있도록 실시할 수도 있다.1 and 2 are perspective views in which one rubber layer of a pneumatic tire belt according to the present invention is cut and a perspective view when the belt cord is a steel cord, where the center portion L width of the belt 1 is tread. It is applied within 50% of the full width T, and the cross-sectional area of the steel cord 2 portion arranged in the center of the belt 1 is made between 10-90% of the steady state cross-sectional area. In addition, instead of partially applying a different cross-sectional area of the cord, the material of the cord is applied differently, and a part having a different Young's Moduls (stiffness) may appear in the central portion (L).
제3도는 본 발명의 벨트로 제조된 공기입 타이어의 개략적인 동작설명도로써, 부분적으로 다른 코드 강성을 갖는 벨트(1)로 인하여 본 발명의 공기입 타이어는 수면 위를 고속으로 주행시 수압에 의하여 트레드면에 일시적으로 종 그루브 형태의 베출홈(3)이 형성되고 상기 배출홈이 스로역할을 하여 타이어의 안티-하이드로 플래닝 성능을 향상시키며, 정상 노면 주행시에는 원상태로 회복되어 타이어의 트랙션 성능, 핸들링 성능, 내마모 성능 등을 개선하는 효과를 기대할 수 있다.3 is a schematic operation explanatory diagram of a pneumatic tire made of the belt of the present invention, due to the belt (1) having a partly different cord stiffness, the pneumatic tire of the present invention is driven by water pressure when traveling on the water at high speed A longitudinal groove-type ejection groove 3 is temporarily formed on the tread surface, and the discharge groove serves as a throw-through to improve the anti-hydro planning performance of the tire, and recovers to its original state during normal road driving, thereby improving the traction performance and handling of the tire. The effect of improving performance, wear resistance, and the like can be expected.
