본 고안은 적은 도로에서의 주행성능 즉 배수성능(=웨트〈Wet〉성능)을 향상시킨 자동차용 타이어에 관한 것이다.The present invention relates to an automobile tire having improved driving performance on a small road, that is, drainage performance (= wet < RTI ID = 0.0 > Wet < / RTI > performance).

젖은 도로에서 자동차를 주행하게 되면 타이어와 도로사이에 수막이 개재되기 때문에 자동차의 주행성능 특히 코너링성능을 크게 저하시키게 된다. 그리하여 타이어에 있어서는 도로와 타이어사이의 물을 효과적으로 배수시키기 위하여 트레드에 여러가지 모양의 홈(Groove;그루브)을 종횡으로 다수 형성시키게 마련이다. 그런데 아무리 종횡으로 그루브를 형성시킨다 하더라도 도로상의 물이 고속으로 주행하는 타이어의 홈에 의하여 모두 밖으로 밀려나가게 한다는 것은 이를 기대할 수 있을 만한 일이 아니다. 물론 단순히 배수성능만을 향상시키려 한다면 넓고 깊은 그루브를 다수 형성시키는 것으로 그 목적을 달성할 수도 있다. 그러나 타이어는 웨트성능만을 향상시켜야 하는 것이 아니라 내마모성, 주행안정성, 승차감 등등을 고려하여야 하므로, 단순히 넓고 깊은 그루브를 다수 형성시킬 수 만은 없는 것이다. 이에 본 고안은 그루브의 넓이나 깊이 및 그루브의 수를 증감시키지 아니하고 단순히 그루브의 내부에 물안내벽을 설치하므로서 배수성능을 크게 향상시킬 수 있도록 한 것이다.When driving a car on a wet road, a water film is interposed between the tire and the road, which significantly reduces the driving performance of the car, particularly the cornering performance. Thus, in the tire, a plurality of grooves (grooves) of various shapes are formed vertically and horizontally in the tread in order to effectively drain the water between the road and the tire. However, even if grooves are formed vertically and horizontally, it is not to be expected that water on the road is pushed out by the grooves of the tires traveling at high speed. Of course, if you only want to improve the drainage performance can be achieved by forming a large number of wide and deep grooves. However, tires should not only improve wet performance but also consider wear resistance, driving stability, ride comfort, etc., and thus simply cannot form a large number of wide and deep grooves. The present invention is to improve the drainage performance by simply installing a water guide wall in the groove without increasing or decreasing the width or depth of the groove and the number of grooves.

이와 같은 본 고안은 트레드에 종횡의 그루브를 형성시켜서 된 것에 있어서, 타이어의 진행방향 전방측에서 횡그루브와 만나는 종그루브상에 횡그루브의 후측벽에 잇대어 안내벽을 설치하므로서, 타이어가 진행함에 따라 타이어와 노면사이의 물이 타이어의 후방으로 압송되지 아니하고 타이어의 좌우 측면으로 배출시킬 수 있도록 하므로서 타이어와 노면사이의 수막현상을 감소시킬 수 있도록 한 것인 바 이와 같은 본 고안을 참부된 도면에 의하면 다음과 같다.The present invention is to form a longitudinal groove in the tread, the guide wall is provided on the longitudinal groove that meets the horizontal groove in the forward direction of the tire to the rear wall of the horizontal groove, as the tire progresses, The water between the tire and the road surface can be discharged to the left and right sides of the tire without being pushed to the rear of the tire, thereby reducing the water film phenomenon between the tire and the road surface. As follows.

자동차용 타이어의 트레드에 종그루브와 횡그루브를 형성시켜서 된 것에 있어서, 타이어의 진행방향(가)의 전방측에서 횡그루브(2)와 만나는 종그루브(1)상에 횡그루브(2)의 후측벽(21)에 잇대어 안내벽(3)을 설치한다. 안내벽(3)의 폭은 당해 안내벽이 설치되는 종그루브(1)의 폭의 50 내지 90%의 폭을 가지게 하는 것이 바람직하며, 안내벽(3)의 높이는 역시 안내벽(3)이 설치되는 당해 종그루브(1)의 깊이의 10 내지 50%정도로 형성시키는 것이 바람직하다.After the longitudinal grooves and the horizontal grooves are formed in the tread of the automobile tire, the rear grooves 2 are disposed on the longitudinal grooves 1 that meet the horizontal grooves 2 at the front side of the traveling direction (a) of the tire. The guide wall 3 is attached to the side wall 21. The width of the guide wall 3 preferably has a width of 50 to 90% of the width of the longitudinal groove 1 on which the guide wall is installed, and the height of the guide wall 3 is also provided by the guide wall 3. It is preferable to form about 10 to 50% of the depth of the longitudinal groove 1 to be used.

이와 같이 구성된 본 고안은 물의 배수량 측면에서 약 150%이상의 효과를 나타냈다. 즉, 출원인 회사제품으로서 승용차용 타이어인 185/65R13(타이어의 코드번호)와 이와 동일한 타이어에 본 고안의 기술을 실시하여서된 타이어를 6가지 7mm의 높이로 물이 찬 아스팔트도로에서 주행하였을 경우에 있어서의 차량의 속도에 따른 배수량을 측정한 결과는 다음의 도표와 같았다.The present invention configured as described above has an effect of about 150% or more in terms of water drainage. That is, when the tire manufactured by applying the technique of the present invention to the same tire as 185 / 65R13 (tire code number) which is a passenger car tire as a product of the applicant company is driven on water-filled asphalt roads with six heights of 7 mm The result of measuring the displacement according to the speed of the vehicle was as shown in the following chart.

위의 도표에서 보는 바와 같이, 100Km/H의 속도로 주행하는 경우에 있어서 종래의 타이어는 약 180ml의 물을 방출하는데 대하여 본 고안의 타이어는 290ml의 물을 방출한다. 따라서 본 고안의 타이어는 배수성능의 점에 있어서 종래의 타이어에 비하여 약 150%이상의 상승효과가 있음을 알았다.As shown in the diagram above, when traveling at a speed of 100 km / h, the conventional tire discharges about 180 ml of water, whereas the tire of the present invention emits 290 ml of water. Therefore, the tire of the present invention was found to have a synergistic effect of about 150% or more in comparison with the conventional tire in terms of drainage performance.

이와 같은 본 고안의 타이어는 상술한 바와 같은 배수성능으로 인하여 젖은 도로에서의 주행성능 즉, 웨트성능이 크게 향상되었음을 인정할 수 있었다.Such a tire of the present invention was able to recognize that the running performance on the wet road, that is, the wet performance was greatly improved due to the drainage performance as described above.
