Abstract

A pneumatic tire of a vehicle is provided to obtain high ground contact point during cornering where a tread wing section contacts the ground by attaching a rubber patch having a high coefficient of friction on the tread wing. A pneumatic tire of a vehicle comprises a tread(1), a sidewall(2), and a bead part(3). A rubber patch(12) having a fairly large coefficient of friction is attached on a tread wing(11) between the tread and a sidewall. The rubber patch is composed of a silica compound having over 70 phr, and has solidity over 68. The rubber patch attached to the tread wing and overlapped with a cap tread. The overlapping length of the rubber patch with the cap tread should be over 5 mm.

본 발명은 차량용 타이어에 관한 것으로, 특히 코너링시 타이어의 접지력을 확보하기위한 차량용 타이어의 개량에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle tire, and more particularly, to an improvement of a vehicle tire for securing a traction force of a tire when cornering.

차량이 직진주행을 할 경우에는 차량의 캠버앵글(camber angle)이 적용된다 하더라도 슬립앵글(slip angle)의 발생량이 거의 없기 때문에 트레드부의 변형이 거의 일어나지 않는다. 따라서 이러한 경우 트레드부를 이루고 있는 컴파운드의 접지력에 따라 핸들링성능이 좌우된다.When the vehicle travels straight, even if the camber angle of the vehicle is applied, since the amount of slip angle is hardly generated, deformation of the tread portion hardly occurs. Therefore, in this case, the handling performance depends on the grounding force of the compound forming the tread portion.

그러나, 급격한 코너링을 할 경우에는 차량의 슬립앵글 및 캠버앵글이 극대화되는 극한조건하에서 트레드부의 변형이 크게 일어나게 된다. However, when sharp cornering is performed, deformation of the tread portion may occur greatly under extreme conditions in which the slip angle and camber angle of the vehicle are maximized.

트레드부의 변형이 심하게 이루어지면 주로 타이어의 숄더부에서 사이드월부로 이어지는 부위가 노면에 접촉하게 되는데 이부분을 주로 이루고 있는 부위는 타이어의 트레드윙부이며, 이러한 트레드윙부는 일반적으로 사이드월과 캡트레드 부의 연결을 용이하게 도와주는 역할을 하는 접지력이 떨어지는 고무로 이루어진다. 이러한 구성은 극한 코너링 상황에서 타이어의 코너링포스(cornering force)가 저하되는 단점이 있다.When the tread part is severely deformed, the part leading from the shoulder portion of the tire to the sidewall part comes into contact with the road surface. The part mainly forming this part is the tread wing part of the tire, and the tread wing part is generally the sidewall and the cap tread part. It is made of rubber with less grip which serves to facilitate the connection. This configuration has a disadvantage in that the cornering force of the tire is reduced in extreme cornering situations.

이에, 본 발명은 트레드와 사이드월 사이인 트레드윙 부위에 마찰계수가 큰 고무패치를 부착시킴으로써 직진주행시 고무패치에 의한 주행성능 감소 및 승차감 저하 등의 문제를 유발하지 아니하면서, 트레드윙 부위가 접지되는 코너링시 높은 접지력을 얻을 수 있는 차량용 타이어를 제공함에 그 목적이 있다. Accordingly, the present invention attaches a rubber patch having a large coefficient of friction to the tread wing portion between the tread and the sidewall, so that the tread wing portion is grounded without causing problems such as reduced driving performance and reduced ride comfort due to the rubber patch when driving straight. It is an object of the present invention to provide a vehicle tire that can obtain a high grip when cornering.

이하, 첨부된 도면에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 트레드(1)와 사이드월(2) 및 비드부(3)로 구성되는 것에 있어서, 트레드(1)와 사이드월(2) 사이인 트레드윙(11) 부위에 마찰계수가 큰 고무패치(12)를 부착시킨 것을 특징으로 한다. The present invention is composed of a tread (1), sidewall (2) and the bead portion (3), the rubber patch having a large coefficient of friction at the tread wing (11) between the tread (1) and the sidewall (2) It is characterized by attaching (12).

본 발명의 차량용 타이어 트레드 압출물의 단면도인 도 1에 도시된 바와 같이, 트레드윙(11)상에 부착된 고무패치(12)가 캡트레드(13)와 겹치는 길이(a)는 5mm 이상인 것이 바람직하다. 상기 고무패치(12)는 70phr 이상의 실리카 컴파운드로 조성되며 경도가 68이상인 고무로 형성시키며, 캡트레드고무의 접지력의 90-110%를 갖도록 구성시키는 것이 바람직하다.As shown in FIG. 1, which is a cross-sectional view of the tire tread extrudate of the present invention, the length a of the rubber patch 12 attached on the tread wing 11 and the cap tread 13 is preferably 5 mm or more. . The rubber patch 12 is formed of a silica compound of 70 phr or more and is formed of a rubber having a hardness of 68 or more, and preferably configured to have 90-110% of the traction force of the cap tread rubber.

도 2는 본 발명의 차량용 타이어의 적용 설명도이다. 도 2의 (가)는 직진주행시의 본 발명 타이어의 단면을, (나)는 코너링시 본 발명 타이어의 단면을 도시하고 있다. 도 2의 (가)에서 도시된 바와 같이 직진주행을 하는 경우에는 타이어의 변형이 거의 없어 본 발명의 고무패치(12)가 접지하지 않아 주행성능에 지장을 주지 않게 된다. 그러나 도 2의 (나)에서 도시된 바와 같이, 급격한 코너링을 하는 경우에는 트레드윙(11) 부분이 지면쪽으로 눌리게 되므로 고무패치(12)가 지면에 닿게 되어 접지력을 향상시킨다. 2 is an explanatory diagram of application of a vehicle tire of the present invention. Figure 2 (a) shows the cross section of the tire of the present invention when driving straight, (b) shows the cross section of the tire of the present invention when cornering. As shown in (a) of FIG. 2, when the vehicle travels straight, there is almost no deformation of the tire so that the rubber patch 12 of the present invention is not grounded, which does not interfere with the driving performance. However, as shown in (b) of FIG. 2, when the sharp cornering is performed, the tread wing 11 part is pressed toward the ground, so that the rubber patch 12 comes into contact with the ground to improve the grounding force.

이상에서 설명한 바와 같이 본 발명에 따르면, 상기 고무패치가 부착된 트레드윙부가 직진주행시 지면에 닿지 않기 때문에 직진주행시 고무패치에 의한 주행성능 감소 및 승차감 저하 등의 문제를 유발하지 아니하면서, 트레드윙 부위가 접지되는 코너링시 높은 접지력을 얻을 수 있어, 코너링시 타이어가 미끄러지는 형상을 방지하는 효과가 있다.As described above, according to the present invention, since the tread wing portion with the rubber patch does not touch the ground when driving in a straight line, the tread wing portion does not cause problems such as a decrease in driving performance and a ride comfort due to the rubber patch during the straight driving. High grounding force can be obtained when cornering is grounded, thereby preventing the tire from slipping.
