The tread part of a conventional tire is composed of a cap tread which is a ground grounding part, an under tread which is a heat dissipating part, and a wing strip. As a result, abnormal abrasion is generated in the early stage to improve wear characteristics of the cap tread portion. The cap tread portion of the tread portion is provided with a rubber layer 11 having excellent wear resistance to form a cap tread having two layers. The thickness of the tread reinforcement part is maintained at 0.2 to 0.5 times the depth of the groove, and the reinforcement tread is partially or totally employed to suppress abnormal abrasion or ground pressure non-uniformity generated in the tread, which is a pneumatic tire ground plane, and improve wear performance. Pneumatic tires with long tire life.

Description

트래드부 내마모성을 향상시킨 공기입 타이어Pneumatic tire which improved tread part wear resistance

본 고안은 타이어의 접지부인 트래드부의 내마모성을 향상시키기 위한 공기입 타이어에 관한 것으로서, 종래의 트래드부는 그 구성부분이 지면과 직접 접촉이 있는 캡트래드 부분과 방열목적과 코드와의 연결부위인 언더트래드, 그리고 윙스트립으로 구성되어 있다. 그러나 지면과 직접적인 접촉을 가지는 캡 트래드부는 사용조건이나 노면상태에 따라 접촉압불균일 등의 원인으로 이상 마모가 발생하는 경우가 있어 이는 타이어의 전체수명을 단축시키는 결과를 초래하고 있다.The present invention relates to a pneumatic tire for improving the wear resistance of the tread portion, which is a ground portion of the tire, and the conventional tread portion is a cap tread portion whose components are in direct contact with the ground, and an undertread which is a connection portion between the heat dissipation purpose and the cord. And wing strips. However, the cap tread portion, which has direct contact with the ground, may cause abnormal wear due to contact pressure unevenness, depending on conditions of use and road surface conditions, resulting in shortening the life of the tire.

종래 타이어의 트래드부가 이상 마모됨에 따라 타이어 전체수명을 단축시키게 되므로 상기 캡트래드부를 개선하여 타이어의 트래드부의 내마모성을 향상시켜 타이어의 수명을 연장하는 데 있다.As the tread portion of the conventional tire is abnormally worn, the entire life of the tire is shortened, thereby improving the cap tread portion, thereby improving wear resistance of the tread portion of the tire, thereby extending the life of the tire.

제 1 도는 종래의 공기입 타이어 상부 단면형상,1 is a conventional pneumatic tire upper cross-sectional shape,

제 2 도는 본 고안의 공기입 타이어 상부 단면형상.2 is a top cross-sectional shape of the pneumatic tire of the present invention.

본 고안은 트래드부의 이상 마모가 초기에 발생, 진행됨에 따라 초기의 이상 마모를 억제하여 전체적인 마모성능을 향상시키고자 제 2 도에서 보는 바와 같이 기존 트래드부 층상에 큰 변화를 가하지 않고 최대한 기존 구조를 유지하면서 초기의 이상 마모 가능성을 억제하기 위하여 트래드의 초기 사용 부분에 마모에 강한 고무(11)를 대체하여 2층의 캡트래드를 구성하는 구조로 되어 있고, 이때 보강부의 트래드층 두께 t는 (0.25~0.5)h로 한다.The present invention aims to improve the overall wear performance by suppressing initial abnormal wear as the abnormal wear of the tread part occurs and progresses at an early stage. As shown in FIG. In order to suppress the possibility of abnormal abrasion at the initial stage while maintaining the tread, the tread layer thickness t of the reinforcement part is formed by substituting the wear resistant rubber 11 at the initial use part of the tread to form a caprad of two layers. To 0.5) h.

보강된 고무는 캡트래드 부의 마모특성을 향상시켜 타이어 내마모 및 수명을 향상시키는 작용을 한다.The reinforced rubber acts to improve the wear resistance and life of the tire by improving the wear characteristics of the cap tread portion.

타이어를 장착후 주행초기에 발생할 수 있는 노면변화, 접지압 불균일 등 여러 요인으로 인한 트래드부의 마모를 최소화하여 초기 이상마모나 이로 인한, 타이어 변형, 수명의 단축 등의 부작용을 최대한 억제할 수 있어 제품 수명연장 및 마모성능 향상의 효과를 얻을 수 있다.Product life can be minimized by minimizing wear and tear on the tread part due to various factors such as road surface change and uneven ground pressure that may occur at the beginning of driving after installing tires as much as possible. Extension and abrasion performance can be improved.

본 고안은 중하중용 공기입 타이어의 지면접촉 부분인 트래드 부분이 접지압 불균일 등 여러가지 이유로 인하여 초기에 이상마모가 발생하여 타이어의 실질수명이 단축되고 있는 바, 이들 요인을 균등화 하거나 최소한으로 억제하여 이상 마모의 발생방지 및 지연효과를 얻어 타이어의 수명 및 성능을 향상하는데 그 목적이 있다.According to the present invention, the tread portion, which is the ground contact portion of the heavy-duty pneumatic tire, is abnormally worn due to various reasons such as uneven ground pressure, and thus the tire's real life is shortened. The purpose is to improve the life and performance of the tire by preventing the occurrence and delay effect of the.
