A protruded part(2) or a concave part which are divided by the wave cuff, of one divided portion is engaged to a protruded part(3) or a concave part of the other divided portion toward a driving direction.

Description

자동차용 스노우 타이어{Snow tire for vehicle}Snow tire for vehicle {Snow tire for vehicle}

본 발명은 자동차용 타이어에 관한 것으로, 특히, 커프의 형상을 개량하여서 된 스노우 타이어에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automobile tires, and more particularly to snow tires made by improving the shape of a cuff.

스노우 타이어는 블록에 커프를 형성시킴으로써 커프로 분할된 블록의 에지가 빙설면을 긁는 에징기능을 발휘하게 하여 빙설 노면에서의 주행 성능인 구동력 및 제동 성능이 향상되도록 형성시켜 왔다.Snow tires have been formed in such a way that the edges of the blocks divided into cuffs have an edging function that scratches the snow surface by improving the driving force and braking performance, which is the driving performance on the snow surface.

종래의 커프의 일반적인 형상은 도 1에 도시된 바와 같다. 그러나, 이러한 커프는 빙설면에서의 구동력이나 제동성능을 향상시키기는 하나, 이러한 커프는 블록을 분할시켜 블록의 강성을 저하시켜서 비 빙설노면인 일반 도로에서의 구동력이나 제동성능이 저하되는 결점이 있었다.The general shape of a conventional cuff is as shown in FIG. However, such cuffs improve the driving force and braking performance on the ice snow surface, but such cuffs have the disadvantage of dividing the block and reducing the rigidity of the block, thereby degrading the driving force and braking performance on the non-snow snow road. .

이에 본 발명은 빙설 노면에서의 주행 성능을 향상시키기 위하여 블록에 커프를 형성시키더라도 블록의 강성 저하 정도를 감소시켜 비 빙설 노면인 일반 노면에서의 스노우 타이어 주행 성능을 향상시켜야 한다는 과제를 해결하고자 한다.Therefore, the present invention is to solve the problem that even if the cuff is formed on the block in order to improve the driving performance on the ice snow road to reduce the stiffness degradation of the block to improve the snow tire driving performance on the non-snow road surface. .

위와 같은 과제를 해결하기 위하여, 본 발명은 블록에 형성시키는 커프의 산이나 골짜기의 폭을 허리의 폭보다 크게 형성시켜서 된 스노우 타이어를 제공한다.     In order to solve the above problems, the present invention provides a snow tire formed by forming the width of the mountain or valley of the cuff formed on the block larger than the width of the waist.

위와 같은 본 발명은, 블록에 형성시키는 커프의 산이나 골짜기의 폭을 허리의 폭보다 크게 형성되어 있으므로, 커프에 의하여 분할된 일측 분할부의 산이나 골짜기가 인접하는 타측 분할부의 골짜기나 산과, 주행 방향으로 맞물리게하여, 커프로 분할된 블록의 주행방향으로의 강성이 강화되게 할 뿐 아니라, 횡방향으로의 힘이 가해지더라도 커프에 의하여 분할된 인접 분할부가 서로 미끄러지며 벌어지지 아니하고 구속되게 하여 코너링 성능 또한 향상시킬 수 있게 하는 효과가 있다.In the present invention as described above, the width of the cuff mountains and valleys formed in the block is formed larger than the width of the waist, so that the valleys or mountains of the other side partitions adjacent to the mountains or valleys of one side partition divided by the cuff, By engaging in the driving direction, not only the rigidity of the block divided by the cuff is strengthened in the running direction, but also the adjacent divisions divided by the cuff slide and restrain each other without being opened even when a lateral force is applied, thereby cornering. It also has the effect of improving performance.

트레드와 사이드월 및 비드부로 구성되고, 트레드부에 블록과 그루브가 형성되며, 블록에 산과 골짜기를 가지는 파형의 커프를 형성시켜서 되는 스노우 타이어에 있어서, 본 발명은, 파형 커프(1)의 산(11)이나 골짜기(12)의 최 광폭부 폭(W)을 허리(13)의 폭(W1)보다 크게 형성시켜 커프(1)에 의하여 분할된 일측 분할부의 돌출부(2)나 요함부가 인접하는 타측 분할부의 돌출부(3)나 요함부와 주행 방향으로 이탈억제맞물림으로 형성된 스노우 타이어를 제공한다.In the snow tire which consists of a tread, a sidewall, and a bead part, a block and a groove are formed in a tread part, and the wave cuff which has a mountain and a valley is formed in a block, this invention provides the mountain ( 11) or the widest part width W of the valley 12 is formed larger than the width W1 of the waist 13 so that the protrusions 2 or recesses of one side part divided by the cuff 1 are adjacent to each other. Provided is a snow tire formed by the release suppression engagement in the traveling direction with the projection (3) or recessed portion of the other side portion.

파형 커프(1)의 산(11)이나 골짜기(12)의 최 광폭부 폭(W)을 허리(13)의 폭(W1)보다 크게 형성시켜 커프(1)에 의하여 분할된 일측 분할부의 돌출부(2)나 골짜기가 인접하는 타측 분할부의 골짜기나 돌출부(3)와 주행 방향으로 이탈억제맞물림 구조를 가지게 하는 본 발명은, 허리(13)의 횡방향선(X)에 대한 산(11)이나 골짜기(12) 쪽 경사각(a, b) 중 하나 이상, 즉, 하나 또는 둘 모두를 둔각으로 형성시킴으로써 실시될 수 있다. 그러나, 첨부된 도면에 도시된 바와 같이, 허리(13)의 횡방향선(X)에 대한 산(11)이나 골짜기(12) 쪽 경사각(a, b) 둘 모두를 동일한 둔각으로 형성시키는 것이 바람직하다. Protruding portion of one side divided by cuff 1 by forming the widest width W of the peak 11 or valley 12 of the corrugated cuff 1 larger than the width W1 of the waist 13. (2) The present invention in which the valley has an escape suppression engagement structure in the traveling direction with the valley or the protrusion 3 of the other side portion adjacent to each other is provided with a peak 11 relative to the lateral line X of the waist 13. Or by forming at least one of the inclination angles a and b toward the valley 12, that is, one or both at an obtuse angle. However, as shown in the accompanying drawings, it is preferable to form both the inclination angles a and b toward the mountain 11 or the valley 12 with respect to the transverse line X of the waist 13 at the same obtuse angle. Do.

또한, 본 발명은 첨부된 도면 도2에 도시된 바와 같이 산(11)이나 골짜기(12)는 둥근 원모양일 수 있으나, 첨부된 도면 도3에 도시된 바와 같이 모서리가 둥근 사다리꼴로 형성될 수 있으며, 기타 임의의 모양으로 형성될 수 있음은 물론이다. 특히 도3에 도시된 실시예에 있어서는 산(11)이나 골짜기(12)의 바닥이 주행방향선에 대하여 직각을 이루게 됨으로, 바닥이 둥근 원모양인 도2의 타이어에 비하여 에징 효과가 향상될 수 있는 효과가 있다. In addition, the present invention as shown in Figure 2 of the accompanying drawings 11 or valley 12 may be a rounded circular shape, as shown in Figure 3 of the accompanying drawings may be formed in a trapezoidal rounded corners. Of course, it can be formed in any other shape, of course. In particular, in the embodiment shown in FIG. 3, the bottom of the mountain 11 or the valley 12 forms a right angle with respect to the direction of travel, so that the edging effect can be improved as compared to the tire of FIG. It has an effect.

본 발명은 커프에 의하여 분할된 일측 분할부의 돌출부와 인접 분할부의 요함부가 이탈억제맞물림으로 연접되게 하여서 되는 타이어에 관한 발명임으로, 본 발명은 일측 분할부의 돌출부와 인접 분할부의 요함부가 이탈억제맞물림되는 기술적 구성을 포함하는 범위내에서, 특히, 허리(13)를 곡선으로 형성시킨다던지 하는 식으로, 이를 임의로 변경 실시할 수 있다. 따라서 본 발명의 기술적 범위는 청구항의 기재에 의해서만 한정된다. The present invention relates to a tire in which a protrusion of one side divided by a cuff and a recess of an adjacent partition are connected to each other by a release suppression engagement. Within the range including the technical configuration to be restrained, particularly, the waist 13 may be formed in a curved manner. Therefore, the technical scope of the present invention is limited only by the description of the claims.
