Abstract
Description
본 발명은 자동차의 공기입 래디얼 타이어에 관한 것으로, 더욱 상세하게는 타이어의 숄더부를 강화시켜 타이어의 품질을 향상시킴은 물론, 제작 공정상의 문제점까지 해결할 수 있는 공기입 래디얼 타이어에 관한 것이다.The present invention relates to a pneumatic radial tire of an automobile, and more particularly to a pneumatic radial tire that can not only improve the quality of the tire by reinforcing the shoulder portion of the tire, but also can solve problems in the manufacturing process.
일반적으로 타이어 내부에 삽입되는 카카스는 몇겹의 코드층으로 되는 것으로, 타이어를 지지하는 가장 큰 역할을 하는 구조부이다. 즉, 카카스는 타이어의뼈대를 이루는 구조부이다.In general, the carcass inserted into the tire is composed of several layers of cords, and is a structural part that plays the biggest role in supporting the tire. In other words, carcass is a structural part that forms the skeleton of the tire.
종래의 래디얼 타이어의 카카스 구조는 타이어 주행방향(원주방향)에 대하여 90도 방향으로 배치되어 있다. 카카스가 타이어 주행방향에 대하여 90도 방향으로 배치되어 있는 종래의 타이어는 숄더부가 약화되는 것이 결점이다. 숄더부는 자동차가 주행할 때 열 및 스트레스를 가장 많이 받는 부분으로서 기존의 주행방향에 대하여 90도 방향으로 배치되는 카카스로는 보강이 미흡하다.The carcass structure of the conventional radial tire is arrange | positioned in the 90 degree direction with respect to a tire running direction (circumferential direction). It is a drawback that the shoulder part is weak in the conventional tire in which carcass is arrange | positioned in the 90 degree direction with respect to a tire running direction. The shoulder part receives the most heat and stress when the vehicle is driven, and the carcass road disposed in a 90 degree direction with respect to the existing driving direction is insufficient in reinforcement.
또한, 종래의 타이어는 카카스가 타이어 주행방향(원주방향)에 대하여 90도 방향으로만 배치되어 있으므로 타이어 가류시에 숄더부의 카카스를 이루는 코드가 노출되는 문제가 있다. 타이어를 몰드 내에 넣어 가류할 때 몰드 내에서 밖으로 밀어내는 강한 팽압을 발생시키는데, 이 때 발생되는 팽압은 숄더부에서 가장 강하게 발생한다. 이 팽압에 의해 숄더부의 고무들이 트레드 또는 사이드월쪽으로 밀려나게 됨으로써 코드가 노출되는 문제가 발생하는 것이다.In addition, in the conventional tire, since the carcass is disposed only in the 90-degree direction with respect to the tire running direction (circumferential direction), there is a problem that the cord forming the carcass of the shoulder portion is exposed when the tire is cured. When the tire is put into the mold and vulcanized, a strong squeezing force is generated, which is pushed out of the mold, and the squeezing force generated at this time occurs most strongly in the shoulder portion. This squeezing causes the rubbers on the shoulder portion to be pushed toward the tread or sidewall, thereby causing the problem of exposing the cord.
본 발명의 목적은 구조적으로 취약한 타이어의 숄더부를 강화시킴으로써 타이어의 성능을 향상시킴은 물론, 가류시 코드가 노출되는 문제를 방지할 수 있는 공기입 래디얼 타이어를 제공하는데 있다.An object of the present invention is to provide a pneumatic radial tire that can improve the performance of the tire by reinforcing the shoulder portion of the structurally weak tire, as well as to prevent the problem of exposing the cord during vulcanization.

상기한 기술적 과제를 달성하기 위한 본 발명의 공기입 래디얼 타이어는 트레드와, 상기 트레드 내부에 삽입되는 벨트와, 상기 벨트의 하부에 삽입되는 카카스를 포함하여 구성되는 공기입 래디얼 타이어에 있어서, 상기 카카스는 숄더부에위치하고 타이어의 원주방향과 동일한 방향으로 배치되는 새로운 카카스를 포함하여 구성되는 것을 특징으로 한다.In the pneumatic radial tire of the present invention for achieving the above technical problem is a pneumatic radial tire comprising a tread, a belt inserted into the tread, and a carcass inserted into the lower portion of the belt, Carcass is characterized in that it comprises a new carcass located in the shoulder portion and arranged in the same direction as the circumferential direction of the tire.
이하, 첨부도면을 참조하여 본 발명의 실시예를 상세히 설명한다. 도 1은 본 발명에 따른 타이어를 나타내는 단면도이고, 도 2는 도 1의 "A"부를 나타내는 사시도이다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention; 1 is a cross-sectional view showing a tire according to the present invention, Figure 2 is a perspective view showing the "A" part of FIG.
본 발명의 공기입 래디얼 타이어(100)는 트레드(10)와, 상기 트레드 내부에 삽입되는 벨트(20)와, 상기 벨트(20)의 하부에 삽입되고 주행방향에 대하여 90도로 배치되는 카카스(30)를 포함하여 구성되는 것에 있어서, 상기 카카스(30)의 상층 숄더부(40)에 배치되고, 타이어의 원주방향(주행방향)과 동일한 방향으로 새로운 카카스(30a)를 적층하는 것이다.The pneumatic radial tire 100 of the present invention has a tread 10, a belt 20 inserted into the tread, and a carcass inserted into a lower portion of the belt 20 and disposed at 90 degrees with respect to a driving direction ( 30), it is arranged in the upper shoulder portion 40 of the carcass 30, and stacks a new carcass 30a in the same direction as the circumferential direction (running direction) of the tire.
즉, 본 발명은 종래의 타이어 중심축방향(가로방향)으로 형성한 카카스(30)의 숄더부(40)에 원주방향(세로방향)으로 새로운 카카스(30a)를 덧입힌 것이다.That is, in the present invention, a new carcass 30a is added in the circumferential direction (vertical direction) to the shoulder portion 40 of the carcass 30 formed in the conventional tire center axis direction (horizontal direction).
여기서, 상기 새로운 카카스(30a)는 최하층의 벨트(20a) 끝단에서 안쪽으로 18-22mm되는 지점에서 시작하여 바깥쪽으로 형성되는 것이 바람직하다.Here, the new carcass 30a is preferably formed outward starting at a point 18-22 mm inward from the end of the belt 20a of the lowermost layer.
또한, 상기 새로운 카카스(30a)의 폭은 70-110mm로 형성되는 것이 바람직하다. 따라서, 타이어의 규격이 195mm(트레드 폭을 말함) 이하의 소형 타이어에는 새로운 카카스(30a)의 폭이 80mm정도가 적당하고, 타이어 규격이 205mm(트레드 폭을 말함) 이상의 중형 타이어에는 새로운 카카스(30a)의 폭이 100mm정도로 형성하는 것이 바람직하다.In addition, the width of the new carcass 30a is preferably formed of 70-110mm. Therefore, a new carcass 30a is suitable for a small tire whose tire size is less than 195 mm (refer to tread width), and a new carcass is suitable for a medium tire having a tire size of 205 mm (refer to tread width). It is preferable to form the width of 30a about 100 mm.
상기와 같이 본 발명은 종래의 카카스의 숄더부위에 직교방향(주행방향)으로 새로운 카카스(30a)를 적층시킴으로써, 구조적으로 취약한 숄더부를 보강할 수 있을 뿐만 아니라, 타이어 가류시에 코드가 노출되는 것을 방지할 수 있다.As described above, according to the present invention, by stacking a new carcass 30a in the orthogonal direction (running direction) on the shoulder portion of the conventional carcass, not only the structurally weak shoulder portion can be reinforced but also the cord is exposed during tire vulcanization. Can be prevented.
