Description

종그루브를 개량하여서 된 스노우 타이어 {Snow tire improved circumferential groove}Snow tire improved circumferential groove

본 발명은 자동차용 스노우 타이에 관한 것으로, 특히, 종그루브를 개량하여서 된 스노우 타이어에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to snow tyres for automobiles, and more particularly to snow tires made by improving longitudinal grooves.

스노우타이어는 설면에서의 주행 및 제동성능이 좋아야 하지만 배수 성능 또한 좋지 않으면 아니된다. 그리하여 종래에는 배수 성능 저하를 방지하기 위하여 종그루브에 배수성능을 제한하는 돌기 등의 설치를 삼가하여 왔으며, 부득이 돌기 등의 돌출부를 설치하더라도 그 크기를 작게 형성시키거나 돌출부를 그루브의 벽면에 형성시켜서 된 타이어를 제공하는 것이 보통이었다.
Snow tires should have good driving and braking performance on snow, but they must also have good drainage performance. Thus, in order to prevent the drainage performance, conventionally, the installation of projections, etc., restricting the drainage performance has been refrained from the longitudinal grooves. It was common to provide old tires.

이에, 본 발명은, 종그루내에 돌출부를 형성시켜 그루브 내로 들어 온 눈에 전단력(剪斷力)을 가하게 하여 설면 주행 성능을 향상시키면서도, 돌출부가 그루브 내에서 작용하는 배수 성능 방해 기능을 최소화하여 배수 성능 또한 양호하게 하여서 되는 타이어를 제공하여야 한다는 과제를 해결하고자 한다.
Accordingly, the present invention, by forming a projection in the bell groove to apply a shear force to the snow that enters the groove to improve the running performance of the snow, while minimizing the drainage performance interference function of the projection in the groove drainage It is intended to solve the problem of providing a tire that also has good performance.

위와 같은 과제를 해결하기 위하여, 본 발명은 종그루내에 돌출부를 형성시키되, 돌출부가 종그루브의 중앙측 벽면 하단으로부터 숄더측 벽면 하단으로 경사진 벽체로 형성되게 하되, 숄더측 벽면 하단으로 향하는 돌출부의 단부가 횡방향그루브의 주행방향 후단벽 단부를 향하게 하여서 되는 타이어를 제공한다.
In order to solve the above problems, the present invention is to form a protrusion in the bell groove, but the protrusion is formed as a wall inclined from the bottom of the central side wall surface of the longitudinal groove to the shoulder side wall bottom, but the projection toward the lower side of the shoulder side wall A tire is provided so that the end portion is directed toward the rear end wall of the transverse groove in the traveling direction.

이와같은 본 발명은, 종그루브에 형성시킨 돌출부가, 종그루내에 들어 온 눈에 전단력(剪斷力)을 가하게하여, 스노우 타이어의 설면 주행 성능을 크게 향상시키는 효과가 있다. 그리고, 본 발명의 타이어는 젖은 노면 주행시에는, 종그루브 내로 들어 온 물을 횡그루브의 입구부로 안내하여 배출되게 함으로서 배수 성능 또한 양호하게 하는 효과가 있다.
The present invention as described above has an effect that the protrusions formed in the longitudinal grooves exert shear force on the snow that has entered the longitudinal grooves, thereby greatly improving the snow running performance of the snow tire. In addition, the tire of the present invention has an effect of improving drainage performance by guiding and discharging water entering the longitudinal groove to the inlet of the lateral groove when driving the wet road surface.

트레드와 트레드 양측에 이어져 형성되는 사이드월 및 사이드월의 단부에 설치되는 비드부로 구성되고, 트레드(1)의 접지면에 주행 방향의 종그루브(2)와 횡방향의 횡그루브(3)가 형성된 스노우 타이어에 있어서, 본 발명은, 그 종그루내(2)에 돌출부(4)를 형성시키되, 돌출부(4)가 종그루브(2)의 트레드 중앙측 벽면(21) 하단으로부터 숄더측 벽면(22) 하단으로 경사진 벽체로 구성시키되, 숄더측 벽면(22) 하단으로 향하는 돌출부(4)의 단부(41)가 횡방향의 횡그루브(3)의 주행방향 후단벽(31) 단부를 향하게 하여서 되는 타이어를 제공한다.It consists of a tread and a sidewall formed on both sides of the tread and a bead portion provided at the end of the sidewall, and a longitudinal groove 2 in the traveling direction and a horizontal groove 3 in the transverse direction are formed on the ground surface of the tread 1. In the snow tire, the present invention provides a projection 4 in the longitudinal groove 2, wherein the projection 4 is a shoulder side wall surface 22 from the lower end of the tread center side wall surface 21 of the longitudinal groove 2. The end 41 of the protrusion 4 facing the lower end of the shoulder side wall 22 is directed toward the end of the rear end wall 31 in the traveling direction of the transverse groove 3 in the transverse direction. Provide tires.

벽체의 형태로 구성되는 돌출부(4)는 그 높이가 1~10mm인 것이 바람직하며, 그 높이가 지나치게 높게 되면 다량의 물이 있는 노면에서의 주행 성능이 불량할 수 있다. 그리고, 돌출부(4)의 폭은 돌출부의 높이에 비례하여 1~10mm의 크기로 형성시키는 것이 바람직하다. 돌출부(4)의 높이가 높으면 그루브 내로 들어 온 눈에 가하는 응력이 커지기 때문이다.It is preferable that the height of the protrusion part 4 formed in the form of a wall is 1-10 mm, and when the height is too high, the driving performance on the road surface with a large amount of water may be poor. In addition, the width of the protrusion 4 is preferably formed in a size of 1 to 10 mm in proportion to the height of the protrusion. This is because the higher the height of the protrusion 4 is, the greater the stress applied to the eye that has entered the groove.

돌출부의(4) 횡단면 형상은 도1에 도시된 바와 같이 직사각형일 수 있으며, 바람직하게는 도 2에 도시된 바와 같이 곡률을 갖는 휘어진 직사각형의 형상을 갖는것이 좋다.The cross-sectional shape of the protrusions 4 may be rectangular as shown in FIG. 1, preferably having a curved rectangular shape having a curvature as shown in FIG. 2.
