Abstract

PURPOSE: A bead filler is provided to have the same slanting on both sides, which causes the inefficient capability of quick turning of vehicles. CONSTITUTION: A pneumatic tire comprises bead part(30), side-wall part(40), thread part(10). Positions of bead filler is installed asymmetrically on the bead part. In the case of left tire of a vehicle, the left bead filler(30a) is made to be slanted outward while the right bead filler (30b), of the same tire, is slanted inwards. Therefore, the lateral strain of tire can be decreased when in quick turnings and the result is the enhancement of cornering capability and the decline of manufacturing cost.

Description

코너링 성능을 향상시킨 공기입 타이어Pneumatic tires with improved cornering performance

본 발명은 코너링 성능을 향상시킨 공기입 타이어에 관한 것으로서, 더욱 상세하게는 비드필러의 설치 구조를 개선하여 차량의 급선회 동작시 타이어의 횡변형량을 감소시켜 코너링 성능을 향상시킬 수 있게 한 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire with improved cornering performance, and more particularly, to improve the installation structure of the bead filler by reducing the lateral strain of the tire during the rapid turning of the vehicle to improve the cornering performance It is about.

일반적으로 차량이 선회 운동을 하는 경우 코너링 포오스(force)에 의해서 타이어는 횡방향으로 변형을 일으키게 된다.Generally, when the vehicle is turning, the tire is deformed in the transverse direction by the cornering force.

이와 같은 타이어의 횡방향 변형은 트래브부의 접지력을 저하시키게 되고, 차량의 코너링 성능을 감소시킨다.Such a lateral deformation of the tire lowers the grip of the trab portion and reduces the cornering performance of the vehicle.

즉, 첨부된 도면 도 1 에 도시되는 바와 같이, 서스팬션이 지지하고 있는 위 부분이 롤(roll) 운동을 하게 되며 이로 인한 좌측 타이어(1)에는 우측 타이어(2)에 비해 수직 하중과 코너링 포오스(force)가 크게 작용하게 된다.That is, as shown in FIG. 1, the upper part supported by the suspension is subjected to roll movement, and thus the left tire 1 has a vertical load and cornering force compared to the right tire 2. (force) is a big effect.

이때 좌측 타이어(1)를 자세히 살펴보면 코너링 포오스(force)에 의해서 타이어가 횡방향으로 변형을 일으키는 것을 알 수 있다.At this time, when looking closely at the left tire (1) it can be seen that the tire is deformed in the transverse direction by the cornering force (force).

이로 인해 좌측 타이어의 트래드부(10)가 심하게 옆으로 밀려나게 되고 숄더의 일부가 지면과 접하게 된다.As a result, the tread portion 10 of the left tire is severely pushed to the side, and a part of the shoulder comes into contact with the ground.

결국 타이어 트래드부(10)의 접지 성능이 저하되어 차량의 코너링 성능이 저하되는 것을 알 수 있다.As a result, it can be seen that the grounding performance of the tire tread portion 10 is lowered and the cornering performance of the vehicle is lowered.

차량이 반대로 왼쪽으로 선회하는 경우에는 우측 타이어(2)에서 수직 하중과 코너링 포오스(force)가 크게 작용하여 트래부의 접지 성능이 저하된다.In the case where the vehicle turns to the left, the vertical load and the cornering force of the right tire 2 greatly act to deteriorate the grounding performance of the track part.

지금까지 몇몇 기술에서는 이와 같은 현상을 해결하기 위하여 타이어 트래드부(10)를 비대칭 구조로 설계하거나 숄더부(11)를 보강시키는 방법을 제시하였다.Until now, some techniques have proposed a method of designing the tire tread portion 10 in an asymmetrical structure or reinforcing the shoulder portion 11 to solve such a phenomenon.

그러나 트래드부(10)를 비대칭 구조로 설계하는 경우 타이어를 성형시키는 금형을 새로 제작하여야 하는 불편과 경제적인 부담이 있으며, 솔더부(11)를 보강시키는 방법 또한 타이어의 제조원가를 상승시키는 문제점이 있는 것이다.However, when the tread portion 10 is designed in an asymmetrical structure, there is an inconvenience and economic burden of newly manufacturing a mold for forming a tire, and a method of reinforcing the solder portion 11 also increases the manufacturing cost of the tire. will be.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 비드필러의 설치 구조를 개선하여 급선회동작시 타이어의 횡변형량을 감소시켜 코너링 성능을 향상시킬 수 있게 한 공기입 타이어를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the present invention improves the installation structure of the bead filler to reduce the lateral strain of the tire during the sharp turning operation to provide a pneumatic tire that can improve the cornering performance There is a purpose.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 즉, 본 발명은 양측 비드필러의 설치 위치를 다르게 구성시킨 것으로, 좌측(차량에 장착시 바깥쪽) 비드필러는 바깥쪽 방향으로 우측(차량에 장착시 안쪽)비드필러는 안쪽 방향으로 기울어지도록 설치시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, according to the present invention, the installation positions of both bead fillers are configured differently, and the left (outside when mounted on the vehicle) bead filler is installed to be inclined inward and the right (behind when mounted on the vehicle) bead filler. It is characterized by being configured.

도 2 및 도 3 에 도시된 바와 같이, 본 발명은 비드부(30)와 사이드월부(40) 및 트래드부(10)로 구성되는 공기입 타이어에 있어서, 상기 비드부(30)를 구성하는 비드필러(30a,30b)의 설치 위치를 좌우가 비대칭되게 형성시켜 구성되는 것이다. 즉, 차량의 좌측에 장착되는 타이어의 경우 좌측(차량에 장착시 바깥쪽) 비드필러(30a)는 바깥쪽 방향으로 치우치게 설치시키고, 우측(차량에 장착시 안쪽)비드필러(30b)는 타이어의 안쪽 방향으로 기울어지도록 설치시켜 구성되는 것으로서, 차량의 우측에 장착되는 타이어의 각 비드필러는 상기 좌측의 타이어와 반대로 형성시켜 구성된다.As shown in Figures 2 and 3, in the pneumatic tire composed of the bead portion 30, the side wall portion 40 and the tread portion 10, the beads constituting the bead portion 30 The mounting positions of the pillars 30a and 30b are formed to be asymmetrical left and right. That is, in the case of the tire mounted on the left side of the vehicle, the bead filler 30a on the left side (outside when mounted on the vehicle) is installed in an outward direction and the right side (inside when mounted on the vehicle) bead filler 30b is It is comprised so that it may incline inward and each bead filler of the tire mounted on the right side of a vehicle is formed so that it may be formed in opposition to the tire of the said left side.

이와 같이 좌우의 비드필러(30a,30b) 기울기를 비대칭으로 형성시킴에 있어서, 좌측비드필러(30a)는 비드코아(301)의 중심점(A)과 비드필러(30a)의 상단 꼭지점(B)을 잇는 선분( )이 수직선(C)과 이루는 종래의 각도(α)보다 5도 내지 15도의 범위 내에서 외측으로 치우치는 각도(α1)로 기울이고, 우측의 비드필러(30b)는 비드코아(301)의 중심점(A')과 비드필러(30b)의 상단 꼭지점(B')을 잇는 선분( )이 수직선(C)과 이루는 이루는 종래의 각도(α) 보다 타이어의 내측으로 각도(α3) 만큼 기울어지도록 설치시켜 구성되는 것이다.As described above, in forming the left and right bead fillers 30a and 30b in an asymmetrical manner, the left bead filler 30a forms a center point A of the bead core 301 and an upper end vertex B of the bead filler 30a. Connecting line segments ( ) Is inclined at an angle α1 that is biased outward within a range of 5 to 15 degrees from the conventional angle α formed with the vertical line C, and the bead filler 30b on the right side is the center point A of the bead core 301. ') And the line segment connecting the upper vertex (B') of the bead filler (30b) ) Is installed so as to be inclined by the angle α3 to the inside of the tire than the conventional angle α which forms the vertical line (C).

이때 상기 우측비드필러가 기울어지는 각도(α3)= K * α1 이고, K= 0.2∼0.8이다.At this time, the angle of inclination of the right bead filler (α3) = K * α1, K = 0.2 to 0.8.

이와 같이 함으로써, 좌측비드필러(30a)가 기울어지는 각도(α1)는 우측비드필러(30b)가 기울어지는 각도(α3) 보다 크게 된다.By doing in this way, the angle (alpha) 1 in which the left bead filler 30a inclines is larger than the angle (alpha) 3 in which the right bead filler 30b inclines.

이와 같이 타이어의 좌우에 설치되는 각각의 비드필러(30a,30b) 기울기를 조정함에 있어서는 각 비드필러를 내외측면에서 감싸는 고무의 두께를 다르게 하여 조정시킬 수 있는 것이다.Thus, in adjusting the inclination of each bead filler (30a, 30b) installed on the left and right of the tire can be adjusted by varying the thickness of the rubber surrounding each bead filler on the inner and outer sides.

본 발명은 전술한 실시 예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

이상에서와 같이 본 발명에 따르면 급선회동작시 타이어의 횡변형량을 감소시켜 코너링 성능을 향상시킴과 동시에 가류금형을 변경시키지 않아도 되어 타이어의 제조원가를 낮출 수 있는 효과가 있는 것이다.As described above, according to the present invention, there is an effect of reducing the manufacturing cost of the tire by reducing the amount of lateral deformation of the tire during sharp turning operation, thereby improving cornering performance and not changing the vulcanization mold.
