Description

내구성 향상을 위한 공기압 타이어{Pneumatic tire}Pneumatic tire for durability

본 발명은 트레드의 내부에서 이 트레드와 카카스를 강하게 묶어 트레드의 강성을 높여주는 제 1, 2 벨트를 보강하는 보강벨트의 개선에 의해 내구성 향상을 위한 공기압 타이어에 관한 것이다.The present invention relates to a pneumatic tire for improving durability by improving the reinforcing belt which reinforces the first and second belts which strongly binds the tread and the carcass inside the tread to increase the rigidity of the tread.

공기압 타이어는 타이어가 노면에 접촉하는 두꺼운 고무층으로 이루어진 트레드(Tread)와, 상기 트레드 가장자리로부터 사이드월의 윗부분을 칭하면서 카카스(Carcass)를 보호함과 동시에 주행시 발생한 열을 발산시키는 숄더(Shoulder)부, 상기 숄더부 아랫부분부터 비드(Bead) 사이의 고무층을 말하며 카카스를 보호하는 사이드월(Sidewall), 상기 트레드 내부에서 트레드의 강성을 강화하는 벨트(Belt), 고무로 토핑(Topping)한 코드(Cord)를 여러 겹으로 겹쳐서 이루어진 타이어의 골격을 이루는 카카스 및, 타이어를 림(Rim)에 장착시키는 비드부로 이루어져 있다.A pneumatic tire is a tread made of a thick rubber layer in which the tire contacts the road surface, and a shoulder that protects the carcass while radiating heat generated while driving while referring to the upper part of the sidewall from the edge of the tread. The side, refers to the rubber layer between the bottom of the shoulder portion (Bead) and sidewall (Sidewall) to protect the carcass, belt (Belt) to strengthen the stiffness of the tread inside the tread, topping (rubber) It consists of the carcass which forms the frame | skeleton of the tire which overlaps cord by several layers, and the bead part which mounts a tire to a rim.

여기서 상기 트레드(1)의 내부에는 도 1과 같이 카카스(3) 상단쪽으로 제 1 벨트(4)와 제 2 벨트(5)들이 타이어의 원주방향을 따라 감겨져 있는데, 상기 제 1, 2 벨트(4,5)의 상하, 좌우방향으로 생기는 변형을 방지하기 위해 보강벨트를 배치하게 된다.Here, the first belt 4 and the second belt 5 are wound along the circumferential direction of the tire in the interior of the tread 1 toward the upper portion of the carcass 3 as shown in FIG. 1. The reinforcing belt is arranged to prevent deformation occurring in the up and down and left and right directions of 4 and 5).

종래 보강벨트는 도 3과 같이 일렬로 배열된 나이론이나 레이온(Rayon), 아라미드(Aramid) 등의 코드(6) 위에 고무층(7)으로 토핑하여 10mm 폭과 1mm의 두께를 가지면서 트레드(2) 내에 위치할 때 제 1, 2 벨트(4,5) 위에서 도 4와 일직선 단면 같은 개념으로 배치되는바, 즉 1mm 두께를 가지는 보강벨트(101)를 중첩하여 이웃한 보강벨트 위로 일부가 겹쳐 배치되면, 약 1mm의 단차(D)가 발생하게 되고, 이 단차(D)를 가진 보강벨트(101) 위쪽으로 트레드(2)의 고무층이 올려지면 그사이에 공간이 발생하여 공기가 유입되어 내구성능에 악영향을 끼치게 될 수 있다.Conventionally, the reinforcing belt is a tread 2 having a thickness of 10 mm and a thickness of 1 mm by topping with a rubber layer 7 on a cord 6 such as nylon, rayon, aramid, and the like arranged in a line as shown in FIG. 3. When placed in the same concept as the straight cross-section as shown in Fig. 4 on the first, second belts (4, 5), that is, overlapping the reinforcement belt 101 having a thickness of 1mm overlapping part over the neighboring reinforcement belt , A step D of about 1 mm is generated, and when the rubber layer of the tread 2 is raised above the reinforcing belt 101 having the step D, a space is generated therebetween and air is introduced to adversely affect the durability performance. May be caused.
