스노우 성능을 향상시킨 자동차용 타이어{Vehicle tire improved snow road performance}Vehicle tire improved snow road performance

본 발명은 자동차용 타이어에 관한 것으로, 특히, 스노우 성능을 향상시켜서 된 타이어에 관한 것이며, 더욱 자세하게 말하면, 그루브의 눈이 효과적으로 배출되게 하여 타이어의 설주 전단 능력을 향상시켜 눈길에서의 주행 성능을 향상시켜서 된 타이어에 관한 것이다.TECHNICAL FIELD The present invention relates to a tire for an automobile, and more particularly, to a tire obtained by improving snow performance. More specifically, the present invention relates to a tire that is improved in snow. It is about a tire made.

자동차 타이어에 있어서 눈길에서의 주행 성능을 개선하기 위하여 실제 적용되는 기술로서는 첫째, 타이어 표면에 스터드를 설치하거나, 둘째, 트레드의 블록에 커프와 그루브를 다수 적용시키거나, 셋째, 낮은 경도의 고무로 트레드를 형성시키는 기술이 알려져 있다.In order to improve driving performance in snow tires, the actual technology applied is to firstly install studs on the tire surface, secondly to apply a large number of cuffs and grooves to the block of the tread, or to use a low hardness rubber. Techniques for forming treads are known.

본 발명은 위와 같은 기술 중 트레드에 그루브를 형성시켜 스노우 성능을 향상시켜서 된 타이어의 개량에 관한 것이다. 타이어에 설치된 그루브는 눈길에서 그루브 안으로 눈이 채워지게 하고, 타이어가 구르면서 그루브에 채워진 설주를 자르 는 힘인 설주 전단응력을 제공한다. 이러한 설주 전단응력이 효과적으로 이용되려면 그루브에 들어와 절단된 설주가 속히 빠져 나가야 한다. 따라서 그루브에서 눈이 잘빠져 나갈 수 있도록 타이어를 설계한다면 좋은 스노우 성능을 발휘할 수 있을 것이다. 그러나, 종래의 타이어에 있어서는 그루브 내에 들어 온 눈이 잘 빠져 나가지 못하여 스노우 성능이 만족스럽지 못한 결점이 있었다.The present invention relates to the improvement of the tire made by improving the snow performance by forming grooves in the tread of the above techniques. Grooves installed on the tires fill the snow into the grooves on the road and provide snow shear stress, the force that cuts the snow filled in grooves as the tire rolls. In order to use this snow shear stress effectively, it is necessary to enter the groove and cut out the snow. So if you design your tires so that you can get out of the grooves, you'll get good snow performance. However, in the conventional tires, there is a drawback that snow performance is not satisfactory because snow entered into the grooves does not come out well.

이에 본 발명은 그루브 내에 들어오는 눈이 신속히 배출되게 하여 타이어의 설부 전단응력을 향상시키어 스노우 성능이 향상된 타이어를 제공하여야 한다는 과제를 해결하고자 한다.Accordingly, the present invention is to solve the problem that the snow entering the grooves to be discharged quickly to improve the tongue shear stress of the tire to provide a tire with improved snow performance.

위와 같은 과제를 해결하기 위하여 본 발명은 그루브 내에 설치되어 있는 마모한계표시구(Tread wear indicator)의 양단이 안내경사면을 가지는 날개로 형성되고 마모한계표시구의 상면에 X형의 커프가 형성된 타이어를 제공한다.In order to solve the above problems, the present invention provides a tire in which both ends of a wear wear indicator installed in a groove are formed of a wing having a guide inclined surface, and an X-shaped cuff is formed on an upper surface of the wear limit indicator. do.

위와 같이 구성되는 본 발명의 타이어에 있어서는, 마모한계표시구가 타이어의 고무 움직임을 받아 그루브 내의 눈을 안내경사면으로 밀어 내어 눈이 그루브로 부터 빠져 나가게 하며, 나아가, 마모한계표시구 상면에 형성된 X자 형의 커프가 트레드의 고무 움직임을 받아 스스로의 움직임을 증폭시키며, 그 증폭되는 마모한계표시구의 움직임으로 그루브 내의 눈이 외부로 빠져나가게 효과를 상승시키는 효과가 있다.In the tire of the present invention configured as described above, the wear limit indicator is subjected to the rubber movement of the tire and pushes the eye in the groove to the guide inclined surface so that the eye exits from the groove, and further, X formed on the upper surface of the wear limit indicator. The cuff of the shape is amplified by the rubber movement of the tread, and the amplification of the wear limit indicator is amplified the effect that the snow in the grooves to escape to the outside.

트레드와 사이드월 및 비드부로 구성되고, 트레드에 그루브(1)가 형성되며, 그루브(2)에 마모한계표시구(2)가 설치된 타이어에 있어서, 본 발명은 마모한계표시구(2)가 그 양측에 경사면(22)을 가지는 날개(21)를 가지고, 그 상면에 X자 형의 커프(3)를 가지는 타이어를 제공한다.In a tire composed of a tread, a sidewall and a bead portion, a groove 1 is formed on the tread, and the wear limit indicator 2 is provided on the groove 2, in the present invention, the wear limit indicator 2 is A tire having wings 21 having inclined surfaces 22 on both sides and an X-shaped cuff 3 on the upper surface thereof is provided.

위와 같은 마모한계표시구(2)에는 염소가스를 분무하여 마찰계수를 떨어뜨리는 경우 설주 전단능력은 더욱 향상될 수 있다. If the wear limit indicator (2) as described above drop the friction coefficient by spraying chlorine gas, the shear shear capacity can be further improved.
