본 고안은 타이어 트레드부의 그루브나 사이프(SIPE)를 그 상부폭 보다 하부폭을 좁게 형성화여 눈길에서의 제동이나 주행 시에 그립력을 향상시킨 스노우용 타이어에 관한 것이다.The present invention relates to a tire for snow, in which grooves or sipes of a tire tread portion are formed to have a lower width than an upper width thereof to improve grip force during braking or driving on snow roads.

종래의 스노우 타이어는 눈길 및 빙판길에서의 그립력을 향상시키기 위해 트레드 블락 내부에 차량 진행 방향에 수직으로 많은 사이프를 주거나, 트레드 컴파운드를 특수컴파운드로 사용하거나, 크기가 작은 트레드블락을 상대적으로 많이 배치시키는 방법이 이용되었다. 이러한 스노우용 타이어는 일반적으로 제동시 트레드 블락의 모서리 부분이 지면에 닿아 눈을 긁으면서 제동이 되게 되는데 종래의 스노우용 타이어는 모두 그루브나 사이프가 타이어 원주에 수직방향으로 형성되어 있어 접지 부분이 날카롭지 못한 경향이 있었다. 따라서 본 고안에서는 타이어의 그루브를 그 하부폭을 상부폭 보다 좁게 형성하여 제동시 힘을 받아 기울어 지면서 접지 부분이 더욱 뾰족하게 돌출되도록 함으로써 그립력을 보강하는데 본 고안의 목적이 있다.Conventional snow tires provide a large amount of sipe in the tread block vertically in the direction of vehicle travel, use a special compound as a compound, or place a relatively large number of small tread blocks to improve grip on snow and ice. Method was used. Such snow tires are generally braked by the edges of the tread block touching the ground and scratching the snow. In conventional snow tires, grooves or sipes are formed vertically in the tire circumference so that the grounding portion is sharp. There was a tendency not to. Therefore, the present invention has a purpose of the present invention to reinforce the grip force by forming a groove of the tire narrower than the upper width of the tire to be inclined under the braking force to protrude the ground portion more sharply.

이하 본 고안에 따른 스노우용 타이어에 대해 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, a snow tire according to the present invention will be described in detail with reference to the accompanying drawings.

눈길에서의 제동력을 증대시키기 위해 본 고안에서는 그루브(1)의 측벽(2)과 트레드면(6)이 이루는 각(θ2)을 예각으로 형성하여 지면(3)과 접촉하는 모서리(A')가 날카롭게 되도록 한다.In order to increase the braking force on the snow road, the present invention forms an angle θ 2 formed between the side wall 2 of the groove 1 and the tread surface 6 at an acute angle to contact the ground 3 with an edge A ′. Make it sharp.

즉, 제2도 a)에 도시된 바와 같이 그루브(1)의 상부폭(B) 보다 하부폭(C)을 좁게 형성함으로써 제동시 혹은 구동시 타이어가 지면과의 마찰로 인해 뒤로 밀리면서 그루브의 형상이 변하게 되는데, 이 때 종래처럼 접지 각도(θ1)가 직각인 경우는 밀리면서 90° 보다 커지게 되므로 접지부분(A)이 완만해 지는 반면, 본 고안에서는 그루브에 힘이 가해지면 그루브의 측벽(2)이 볼록하게 되는 경향들이 나타나면서 접지 모서리(A')가 더욱 첨예하게 돌출되어 지면과 접함으로써 쉽게 제동이 걸리게 되는 것이다.That is, as shown in FIG. 2 a), the lower width C is made narrower than the upper width B of the groove 1 so that the tire is pushed backward due to friction with the ground during braking or driving. When the ground angle (θ 1 ) is a right angle as in the prior art, the shape is changed, but the ground portion (A) becomes gentle because the ground portion (A) is gentle, whereas in the present invention, when the force is applied to the groove, The tendency for the side wall 2 to be convex appears, and the ground edge A 'protrudes more sharply so that it is easily braked by contacting the ground.

이상과 같이 본 고안은 그루브 직각을 이루는 타이어 보다 더 효과적으로 제동을 걸 수 있게 되어 빙판길이아 혹은 눈길에서의 미끄러짐을 방지하고 미끄럼에 의한 사고를 다소 줄일 수 있는 잇점이 있다.As described above, the present invention can apply braking more effectively than tires forming a right angle to the groove, thereby preventing slipping on ice roads or snow roads and reducing accidents caused by sliding.
