고성능 타이어의 트레드 패턴구조{Tread pattern design of ultra high performance tire}Tread pattern design of ultra high performance tire

본 발명은 스포츠 유틸리티 차량(Sports utility Vehicle)용 고성능 타이어의 트레드 패턴구조에 관한 것으로, 더욱 상세하게는 핸들링과 제동성능의 향상이 이루어지는 고성능 타이어의 트레드 패턴구조에 관한 것이다.The present invention relates to a tread pattern structure of a high performance tire for a sports utility vehicle, and more particularly, to a tread pattern structure of a high performance tire that improves handling and braking performance.

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 V형상으로 일반 승용차용 래디얼 타이어에 비하여 블록형상이 크게 설계되어 핸들링 및 제동성능의 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. The pattern characteristics of these tires are V-shaped and radial for general passenger cars. Compared to tires, the block shape is designed to be larger, and the driving and braking performance is improved.

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 위해 발명된 것으로, 기존 싱글(Single) 경사각을 가진 V형 패턴의 타이어에 비하여 고속 주행시 제동성능과 코너링 성능이 향상된 듀얼(Dual) 경사각을 가진 고성능 타이어의 트레드 패턴구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, and a high-performance tire having a dual inclination angle with improved braking performance and cornering performance at high speeds compared to a V-type tire having a conventional single inclination angle. The purpose is to provide a tread pattern structure.

상기와 같은 목적을 가진 본 발명은 여러 개의 홈과 2개의 동일한 피치가 하나의 피치군으로 이루어지면서 다수개의 피치군이 반복 재배치되는 블록들을 갖춘 타이어의 트레드 패턴구조에 있어서, 상기 트레드의 센터라인(CL)을 기준으로 제 1 블록 엣지부의 경사각( 1)이 10°∼20°각도로 형성되고 제 2 블록 엣지부의 경사각( 2)이 10°∼20°각도로 형성되어 이루어진 이중 경사각을 갖춘 구조로 되어 있다.According to the present invention having the above object, in the tread pattern structure of a tire having blocks in which a plurality of grooves and two identical pitches are formed of one pitch group and a plurality of pitch groups are repeatedly rearranged, the center line of the tread ( Inclination angle of the first block edge portion 1 ) is formed at an angle of 10 ° to 20 ° and the inclination angle of the second block edge portion ( 2 ) is a structure having a double inclination angle formed by 10 ° to 20 ° angle.
