Description

커프의 형상을 개량한 스노우 타이어{Snow tire improved kerf structure}Snow tire improved kerf structure

본 발명은 자동차용 타이어에 관한 것으로, 특히, 블록에 형성시킨 커프의 형상을 개량하여 구동 및 제동 성능을 향상시키는 스노우 타이어에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automobile tires, and more particularly, to a snow tire that improves driving and braking performance by improving the shape of the cuff formed on the block.

스노우 타이어에 있어서는, 트레드에 커프를 형성시킴으로서 주행시 커프 입구부 에지가 노면을 긁어 구동 및 제동 성능을 향상시키게 하여 왔다. 그리고, 커프에 의한 에징 효과를 향상시키기 위하여는 트레드의 블록에 형성시키는 커프(Kerf)의 수효를 증가시킨다던지, 커프의 총 길이를 길게 형성시킨다던지 또는 커프의 폭을 증가시키는 수단이 채택되어 왔다.       In snow tires, a cuff is formed in the tread, so that the cuff inlet edge scrapes the road surface during driving to improve driving and braking performance. In order to improve the edging effect by the cuff, a means of increasing the number of kerfs formed in the block of the tread, lengthening the total length of the cuff, or increasing the width of the cuff has been adopted. .

그러나, 이와 같은 종래의 타이어에 있어서는, 주행시, 커프의 내부로 들어 간 눈이 빠져 나가지 아니하고 남아 있어 에징 효과를 기대하기 어려울 뿐 아니라, 커프의 수효나 총 길이 또는 폭을 증가시키게 되면 블록의 강성이 저하되는 결점이 있다.However, in such a conventional tire, when driving, the snow entering the inside of the cuff remains without falling out and it is difficult to expect an edging effect, and when the number of cuffs and the total length or width are increased, the rigidity of the block is increased. There is a deterioration defect.

이에 본 발명은 커프 내부로 들어 간 눈이 용이하게 배출되어 커프의 단부가 에징 기능을 제대로 수행하게 하면서 나아가 블록의 강성이 저하되는 것을 감소시켜서 된 스노우 타이어를 제공하여야 한다는 과제를 해결하고자 한다. Accordingly, the present invention is to solve the problem that the snow tire is provided by easily discharged the snow entered into the cuff so that the end of the cuff properly performs the edging function and further reduce the degradation of the rigidity of the block.

위와 같은 과제를 해결하기 위하여 본 발명은, 블록에 형성시키는 커프의 바닥에 관로를 형성시키되, 관로는 커프의 폭보다 큰 직경을 가지며 블록에 접하는 그루브에 연통되게 하여서 된 스노우타이어를 제공하며, 나아가, 커프의 폭을 크게 형성시키되 커프를 형성시키는 블록의 벽면에 돌출부를 형성시켜서 된 스노우타이어를 제공한다.In order to solve the above problems, the present invention provides a snow tire formed by forming a conduit at the bottom of the cuff to be formed in the block, the conduit has a diameter larger than the width of the cuff and in communication with the grooves in contact with the block, further The present invention provides a snow tire that has a large width of a cuff but a protrusion formed on a wall surface of the block forming the cuff.

블록에 형성시키는 커프의 바닥에, 커프의 폭보다 큰 직경을 가지며 블록에 접하는 그루브에 연통되는 관로를 형성시켜서 된 본 발명의 스노우타이어는, 커프 내부로 들어오는 눈이 커프 바닥의 관로를 통하여 그루브로 배출되어 커프가 눈으로 채워지는 현상을 감소시켜 커프의 에징효과가 감소되는 일을 방지할 수 있는 효과가 있다. In the snow tire of the present invention, the snow tire of the present invention is formed at the bottom of the cuff to be formed in the block and has a diameter larger than the width of the cuff and communicates with the groove in contact with the block. By reducing the phenomenon that the cuff is filled with eyes discharged, there is an effect that can prevent the edging effect of the cuff is reduced.

또한, 본 발명은, 커프의 폭을 크게 형성시키더라도, 커프를 형성시키는 블 록의 벽면에 돌출부를 형성시킴으로서, 커프의 폭을 크게 형성시켜 에징 효과를 향상시키면서도, 돌출부로 인하여 블록의 표면적 감소효과를 적게하여 블록 강성 저하 염려를 해소시킬 수 있는 효과가 있다.In addition, the present invention, by forming a protrusion on the wall surface of the block to form the cuff, even if the width of the cuff is made large, thereby increasing the width of the cuff to improve the edging effect, while reducing the surface area of the block due to the protrusion By reducing the effect of reducing the block stiffness is effective.

트레드부와 트레드에 연결되는 트레드 양측의 사이드월 및 사이드월의 양 단부에 설치되는 비드부로 구성되고, 트레드에 블록(1)과 그루브가 형성되며 블록(1)에 커프(2)가 형성되는 스노우 타이어에 있어서, 본 발명은, 블록(1)에 형성시키는 커프(2)의 바닥에 관로(3)를 형성시키되, 관로(3)는 커프(2)의 폭(W)보다 큰 직경을 가지며 블록(1)과 커프(2)의 길이 방향으로 접하게 설치된 그루브에 연통되게 형성시켜서 된 스노우타이어를 제공한다. 이러한 본 발명의 타이어는 상술한 바와 같이, 관로(3)를 통하여 커프(2)에 들어 온 눈이 배출되게 하여 커프(2)가 눈으로 채워지는 현상을 방지하는 효과가 있다. It is composed of a tread portion and sidewalls on both sides of the tread connected to the tread and bead portions provided at both ends of the sidewall, and a block (1) and a groove are formed in the tread and the cuff (2) is formed on the block (1). In the tire, the present invention provides a conduit (3) formed at the bottom of the cuff (2) formed in the block (1), wherein the conduit (3) has a diameter larger than the width (W) of the cuff (2). Provided is a snow tire formed in communication with a groove provided in contact with the longitudinal direction of (1) and the cuff (2). As described above, the tire of the present invention has the effect of preventing the phenomenon in which the cuff 2 is filled with snow by allowing the snow entering the cuff 2 through the conduit 3 to be discharged.

본 발명은 이에서 나아가, 첨부된 도면에 도시된 바와 같이, 위의 관로(3)가 커프(2)의 주행방향측 벽면(21) 쪽으로 편심되게 위치된 스노우 타이어를 제공한다. 이는 벽면(21)에 넓은 표면적을 제공하여 벽면(21)부의 강성을 저하시켜 주행시 에지 부분(211)에서의 굴곡 정도(a)를 크게하여 에징효과를 향상시키게 하는 효과가 있다.  The present invention further provides a snow tire in which the above conduit 3 is eccentrically positioned toward the running direction side wall 21 of the cuff 2, as shown in the accompanying drawings. This has the effect of providing a large surface area on the wall surface 21 to reduce the rigidity of the wall surface 21 portion to increase the degree of bending (a) in the edge portion 211 during driving to improve the edging effect.

본 발명은, 또한, 커프(2)의 폭을 크게 형성시키되 커프(2)를 형성시키는 커프(2)의 주행방향측 벽면(21)에 돌출부(4)를 형성시켜서 된 스노우타이어를 제공한 다. 이러한 돌출부(4)는 커프(2)의 폭(W)을 크게 형성시키더라도 블록의 강성 저하를 방지할 수 있게 한다. 따라서, 부분적으로나마, 커프(2)의 폭을 크게 형성시켜 에징 효과를 향상시킬 수 있게 한다.The present invention also provides a snow tire in which a protrusion 4 is formed on the wall surface 21 of the cuff 2 in a traveling direction to form a large width of the cuff 2 and to form the cuff 2. . Such a protrusion 4 can prevent a decrease in rigidity of the block even when the width W of the cuff 2 is made large. Therefore, in part, the width of the cuff 2 is made large so that the edging effect can be improved.

특히, 본 발명은, 커프(2)의 주행방향측 벽면(21)에 돌출부(4)를 형성시켜서 된 스노우타이어를 제공함에 있어서, 돌출부(4)는 그 외표면(41)이 블록(1)의 접지면과 동일한 평면을 이루게 형성시켜서 된 타이어를 제공함으로썬, 돌출부(4)의 에지(42)가 주행시 에징 작용을 하게 하는 것이 바람직하다. In particular, the present invention provides a snow tire formed by forming a protrusion 4 on the running-side wall surface 21 of the cuff 2, wherein the protrusion 4 has an outer surface 41 of which is a block 1. By providing a tire that is formed in the same plane as the ground plane, the edge 42 of the protrusion 4 preferably makes an edging action during driving.

돌출부(4)는 첨부된 도면 도1에 도시된 바와 같이, 커프(2)의 주행방향측 벽면(21) 외측 상부 양단에 형성시키는 것이 바람직하나, 첨부된 도면 도2에 도시된 바와 같이, 커프(2)의 주행방향측 벽면(21) 외측 상부 중앙에 형성시킬 수도 있다.The protrusion 4 is preferably formed at both ends of the outer side of the cuff 2 in the running direction side wall surface 21, as shown in FIG. 1, but as shown in FIG. It can also be formed in the center of the outer side of the running direction side wall surface 21 of (2).
