Description
본 발명은 차량용 타이어에 관한 것으로, 특히 노면 견인력 향상과 스노우 성능이 향상되는 사계절용 고성능 타이어의 트레드 패턴구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle tire, and more particularly, to a tread pattern structure of a high performance tire for four seasons in which road traction and snow performance are improved.
최근 차량용 타이어에 있어서 고성능 타이어는 넓은 트레드 그루브들과 조화로운 컴파운드의 결합으로 조정 안정성이 뛰어나기 때문에 소비자들로부터 선호도가 증가하는 추세이다.In recent years, high-performance tires in car tires have a tendency to increase in preference from consumers because of the excellent adjustment stability by combining a wide tread grooves and a harmonious compound.
일반적으로 UHPT(Ultra High Performance Tire)라고 구분되는 고성능 타이어에 대한 정의는 타이어 제조사마다 다소 다르지만, 통상 고속주행이 가능하고 편평비가 낮은 타이어를 칭하며, 이들 타이어의 패턴 특징은 일반 승용차용 래디얼 타이어에 비하여 블록형상이 크게 설계되어 핸들링 및 제동 성능의 향상을 추구하고 있다.The definition of high-performance tires, which are generally classified as UHPT (Ultra High Performance Tires), is somewhat different for each tire manufacturer, but generally refers to tires capable of high-speed driving and low flatness, and the pattern characteristics of these tires are higher than those of a radial tire for a passenger car. The large block shape is designed to improve handling and braking performance.
그러나 일반적인 고성능 타이어들을 저편평비 및 큰 블록형상으로 승차감 저하 및 패턴소음이 일반 승용차용 타이어에 비하여 다소 큰 단점이 있으며, 또한 커프(Kerf)가 없이 큰 블록으로만 이루어진 패턴은 눈길 및 빙판길에서의 핸들링 및 제동성능이 떨어지기 때문에 겨울철에 사용하는 것은 위험부담이 있었다.However, general high-performance tires have a low flatness and large block shape, and the ride comfort and pattern noise are somewhat larger than those for general passenger tires. Also, a pattern consisting of large blocks without kerf is used on snow and ice roads. Because of poor handling and braking performance, use in winter was a risk.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위하여 발명된 것으로, 노면 견인력 향상과 눈길 또는 빙판길에서의 핸들링 성능 및 구제동 성능인 스노우 성능을 향상시킨 사계절용 고성능 타이어의 트레드 패턴구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, to provide a tread pattern structure of the four-season high-performance tires to improve the road traction and snow performance, which is the handling performance and the braking performance on the snow road or ice road. The purpose is.
상기와 같은 본 발명은 여러 개의 홈과 등간격으로 재배치되는 블록들을 갖춘 타이어의 트레드 구조에 있어서, 상기 트레드의 센터라인(CL)을 기준으로 양쪽으로 2개씩 4개의 홈들이 형성되고, 이 센터라인(CL)을 기준으로 양쪽으로 배치되는 각각의 블록들에는 그 중간에 커프들이 형성되며, 상기 센터라인(CL)의 지점으로 제 1 홈의 위치(Lg1)는 트레드 폭(TW)의 4 ~ 5%, 제 2 홈의 위치(Lg2)는 트레드 폭(TW)의 30 ~ 32% 정도에 배치되어 있다.In the present invention as described above, in the tread structure of a tire having a plurality of grooves and blocks rearranged at equal intervals, four grooves are formed on each side of the tread based on the center line CL of the tread. Cuffs are formed in each of the blocks arranged at both sides with respect to CL, and the position Lg 1 of the first groove as a point of the center line CL is 4 to 4 of the tread width TW. The position Lg 2 of 5% and 2nd groove | channel is arrange | positioned about 30 to 32% of the tread width TW.
이하, 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 고성능 타이어의 트레드 패턴구조를 나타낸 패턴 설명도로서, 본 발명은 여러 개의 홈들과 등간격으로 재배치되는 블록들을 갖춘 타이어의 트레드 구조에 있어서, 상기 트레드(8)의 센터라인(CL)을 기준으로 양쪽으로 2개씩 4개의 주홈(1, 2)이 배치되되, 상기 제 1 주홈(1)의 위치(Lg1)는 트레드 폭(TW)의 4 ~ 5%, 상기 제 2 주홈(2)의 위치 (Lg2)는 트레드 폭(TW)의 30 ~ 32% 정도에 형성되고, 이 센터라인(CL)을 기준으로 양쪽으로 배치되는 각각의 블록(3a, 3b, 3c, 3d)들에는 그 중간에 커프(Kerf, 4) 들이 형성되어 있다.1 is a pattern explanatory view showing a tread pattern structure of a high-performance tire according to the present invention, the present invention is a center line of the tread 8 in the tread structure of the tire having blocks that are rearranged at equal intervals with a plurality of grooves Four main grooves 1 and 2 are disposed on each side based on CL, and the position Lg 1 of the first main groove 1 is 4 to 5% of the tread width TW and the second. The position Lg 2 of the main groove 2 is formed at about 30 to 32% of the tread width TW, and each of the blocks 3a, 3b, 3c, and 3d disposed on both sides of the center line CL. ) Cuffs (Kerf, 4) are formed in the middle.
그리고 상기 제 1 주홈(1)과 제 2 주홈(2) 사이에 배치되는 횡홈(5)의 각도(α1, α2)는 피치 A(6)와 피치 B(7)에 대하여 63˚~ 68˚의 각도로 설정하고, 대중소 피치를 2종류로 이루어져 있으며, 전체 피치 배열(LA, LB, MA, MB, SA, SB)은 6개의 조합으로 이루어져 있다.In addition, the angles α1 and α2 of the horizontal grooves 5 disposed between the first main groove 1 and the second main groove 2 are 63 ° to 68 ° with respect to the pitch A (6) and the pitch B (7). Set at an angle, two kinds of pitches are formed, and the total pitch arrays LA, LB, MA, MB, SA, and SB are composed of six combinations.
따라서 본 발명은 트레드(8)에 형성된 4개의 주홈(1, 2)들에 의해 배수성이 향상되면서, 각 블록(3a ~ 3d)에 형성된 커프(4) 들에 의해 스노우 성능(눈길 또는 빙판길에서의 핸들링 성능과 구제동 성능)이 향상된다.Therefore, the present invention is improved in the snow performance (snow or ice road) by the cuffs (4) formed in each block (3a ~ 3d), while the drainage is improved by the four main grooves (1, 2) formed in the tread (8) Handling performance and braking performance) is improved.
그리고 상기 6개의 피치배열(LA, LB, MA, MB, SA, SB)에 의해 패턴 소음의 저감이 이루어지도록 되어 있다.The six pitch arrays LA, LB, MA, MB, SA, and SB reduce the pattern noise.
한편, 도 2와 도 3은 225/40ZR18 Size로 본 발명과 기존 고성능 타이어를 제조하여 접지형상 비교도 및 실차시험 결과 비교표로서, 도 3에서 본 발명의 사계절용 고성능 타이어(B)와 (B1), (B2)는 서로 동일한 패턴구조를 갖으나, 재료의 컴파운드를 달리한 것으로, 본 발명(B, B1, B2)은 마른 노면 견인력에서 종래 고성능 타이어(A)보다 다소 떨어지나 나머지 특성에서는 모두 우수함을 알 수 있다.On the other hand, Figures 2 and 3 is a comparison chart of the ground shape and the actual vehicle test results by manufacturing the present invention and the existing high performance tires in 225 / 40ZR18 Size, Figure 4 in the high-performance tires (B) and (B 1) ), (B 2 ) have the same pattern structure, but different compound of the material, the present invention (B, B 1 , B 2 ) is slightly lower than the conventional high performance tire (A) in dry road traction force, but the remaining characteristics In all it can be seen that excellent.
그리고 본 발명(B)과 종래 고성능 타이어(A)의 고무 특성은 다소 비슷하고, 본 발명의 다른 실시예들(B1, B2)은 종래 타이어에 비해서 고무가 다소 연질 성분을 사용한 관계로 스노우 성능의 향상정도가 더 큼을 알 수 있다.And the rubber properties of the present invention (B) and the conventional high performance tire (A) is somewhat similar, and other embodiments (B 1 , B 2 ) of the present invention is a snow compared to the conventional tire because the rubber uses a somewhat soft component You can see that the improvement in performance is greater.
상기와 같이 본 발명에 따른 사계절용 고성능 타이어의 패턴구조는 종래의 고성능 타이어에 비해 마른 노면에서의 성능이 다소 떨어지나, 젖은 노면의 견인력과 스노우 성능 등은 향상됨을 알 수 있어 운전자에게 보다 안전한 타이어를 제공할 수 있는 잇점을 갖는다.As described above, the pattern structure of the four season high-performance tire according to the present invention is slightly reduced performance on the dry road surface compared to the conventional high-performance tire, it can be seen that the traction and snow performance of the wet road surface is improved, so that a safer tire for the driver It has the advantage that it can provide.
