Abstract

PURPOSE: A pneumatic tire against a flat tire is provided to improve driving experience and steering stability by increasing the stiffness of reinforcing rubber in the flat tire with modifying the shape of reinforcing rubber. CONSTITUTION: A pneumatic tire is composed of a tread part(1), a side wall(2) and a bead part(3). A reinforcing rubber(4) is installed in the side wall. The lower part of the reinforcing rubber is fixed in the side wall, and the upper part of the reinforcing rubber is spaced from the side wall. A fitting sill(5) is formed in the lower part of the tread part to fit the upper end of the reinforcing rubber, and made of rubber. The lower part of the reinforcing rubber is fixed in the side wall from a bead toe(30) and the upper end of a bead filler(31). Impact is buffered with transmitting through the side wall from the tread part by separating the reinforcing rubber from the middle of the side wall. The downward movement of the tread part is restricted with fitting the end of the reinforcing rubber to the fitting sill in decreasing internal pressure from a flat tire. Lowering of driving experience or steering stability is prevented with keeping the stiffness of the reinforcing rubber.

Description

펑크 대비용 공기입 타이어 {Run-flat tire}Puncture-ready pneumatic tires {Run-flat tire}

본 발명은 사이드월부의 강성을 보강하여 타이어 펑크 시에도 일정한 속도로 주행을 이룰 수 있게 하는 펑크 대비용 타이어에 관한 것으로서, 더욱 상세하게는 타이어의 사이드월 내측에 설치되는 보강고무에 의한 조종안정성과 승차감의 저하를 방지할 수 있게 하는 펑크 대비용 공기입 타이어에 관한 것이다.The present invention relates to a puncture-ready tire that can reinforce the rigidity of the sidewall portion to achieve a constant speed even when the tire is punctured, and more particularly, to the steering stability by the reinforcement rubber installed inside the sidewall of the tire. The present invention relates to a pneumatic tire prepared for puncture that can prevent a deterioration of ride comfort.

일반적으로 공기입 타이어는 타이어의 내부에 충전되는 공기압에 의하여 차량의 무게를 지탱하는 것으로 타이어의 내부에 공기압이 존재하지 않게 되면 타이어의 내부면이 림에 밀착되어 주행을 이룰 수 없게 된다.In general, the pneumatic tire supports the weight of the vehicle by the air pressure charged in the tire, and when there is no air pressure inside the tire, the inner surface of the tire is in close contact with the rim, thereby preventing driving.

이와 같은 상태에서 무리하게 주행을 하게 되면 타이어의 사이드월부가 파손되어 펑크를 수리한다 하더라도 더이상 타이어로써 기능을 발휘하지 못하게 되는 것이다.If you drive excessively in this state, even if the sidewall of the tire is damaged and repair the puncture will no longer function as a tire.

이와 같은 문제점을 해결하기 위한 종래의 수단으로써 첨부된 도면 도 1 에 도시되는 바와 같이, 사이드월부(2)의 내측면에 보강고무(4)를 설치시켜 타이어의 내부에 공기압이 존재하지 않는 경우 타이어의 사이드월부(2)가 차량의 무게를 지탱할 수 있게 하는 것이 제공된 바 있다.As shown in the accompanying drawings as a conventional means for solving such a problem, as shown in Figure 1, when the reinforcement rubber (4) is installed on the inner surface of the side wall portion (2) tires when there is no air pressure inside the tire It has been provided for the sidewall portion 2 of the to support the weight of the vehicle.

그러나 상기한 바와 같은 종래의 기술은 사이드월부(2)의 강성이 필요이상으로 강하여 노면으로부터 사이드월부를 통하여 전가되는 충격이 사이드월부에서 완충되지 못하고 그대로 차량에 전가되어 승차감과 조종안정성이 매우 불량한 문제점이 있는 것이다.However, the conventional technology as described above has a problem that the rigidity of the side wall portion 2 is stronger than necessary, so that the shock transmitted from the road surface to the side wall portion is not buffered at the side wall portion and is transferred to the vehicle as it is, so that the riding comfort and steering stability are very poor. Is there.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 사이드월부의 내측에 설치되는 보강고무의 형상을 개선하여 평상시에는 보강고무의 강성이 사이드월의 강성에 영향을 주지 않게 하고, 타이어의 펑크시에만 보강고무의 강성이 작용토록함으로써 보강고무로 인한 승차감과 조종안정성을 불량함을 해소시킬 수 있게 하는 펑크대비용 타이어를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the present invention improves the shape of the reinforcement rubber is installed on the inner side of the side wall so that the stiffness of the reinforcement rubber usually does not affect the rigidity of the side wall, tires The purpose of the present invention is to provide a puncture-cost tire that enables the rigidity of the reinforcement rubber to act only during the puncture of the vehicle, thereby eliminating the poor ride comfort and steering stability due to the reinforcement rubber.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 본 발명은 비드부와 사이드월부 및 트래드부로 구성되고, 상기 사이드월의 내부에 보강고무가 설치되는 펑크대비용 타이어에 있어서, 상기 보강고무의 하단부만을 고정결합시키고 상단부는 사이드월 내측면으로부터 이격시키며, 트래드부의 저부에 상기 보강고무의 상단부가 걸리어지는 걸림턱을 형성시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. The present invention is composed of a bead portion, a side wall portion and a tread portion, in the puncture expensive tire that is installed in the reinforcement rubber inside the side wall, fixedly coupled to the lower end of the reinforcement rubber and the upper end is spaced apart from the inner side wall The lower end of the tread portion is characterized in that it is configured to form a locking step that the upper end of the reinforcing rubber is caught.

도 1 에 도시된 바와 같이, 본 발명은 비드부(3)와 사이드월부(2) 및 트래드부(1)로 구성되고, 상기 사이드월(2)의 내부에 보강고무(4)가 설치되는 펑크대비용 타이어에 있어서, 상기 보강고무(4)의 하단부(40)만을 고정결합시키고, 상단부(41)는 사이드월(2) 내측면으로부터 이격시키며, 트래드부(1)의 저부에 상기 보강고무(4)의 상단부(41)가 걸리어지는 걸림턱(5)을 형성시켜 구성되는 것으로, 상기 걸림턱(5)의 재질은 보강고무(4)의 재질과 동일한 고무조성물로 형성되는 것이다.As shown in FIG. 1, the present invention includes a bead part 3, a side wall part 2, and a tread part 1, and a puncture in which a reinforcing rubber 4 is installed inside the side wall 2. In the contrast tire, only the lower end 40 of the reinforcement rubber 4 is fixedly coupled, the upper end 41 is spaced apart from the inner side of the side wall 2, and the reinforcement rubber ( 4) is formed by forming a catching jaw (5) to the upper end portion 41 is caught, the material of the locking jaw (5) is formed of the same rubber composition as the material of the reinforcing rubber (4).

또한 상기 보강고무(4)의 하단부(40)를 사이드월(2)에 고정결합시킴에 있어서는 비드토우(30)부분부터 비드필러(31)의 상단까지만을 고정결합시키는 것이 바람직하다.In addition, when the lower end portion 40 of the reinforcement rubber 4 is fixedly coupled to the side wall 2, it is preferable that only the fixed to the upper end of the bead filler 31 to the bead filler 31.

이와 같이 구성되는 본 발명은 평상시에는 보강고무(4)가 사이드월(2)의 충격완화부위(사이드월의 중간부분)로부터 이격됨에 따라 트래드부(1)로부터 전가되는 충격이 사이드월(2)을 거치면서 완충되어 승차감과 조종안정성이 저하되는 것을 방지하다가 타이어에 펑크가 발생되어 타이어의 내압이 떨어지는 경우에는 트래드부(1)가 하강되면서 보강고무(4)의 선단부가 걸림턱(5)에 걸리어지면서 트래드부(1)의 계속되는 하강동작을 저지하여 타이어의 내부에 공기압이 존재하지 않더라도 주행을 계속할 수 있게 되는 것이다.In the present invention constituted as described above, the impact that is transferred from the tread portion 1 as the reinforcement rubber 4 is spaced apart from the impact relief portion (middle part of the sidewall) of the sidewall 2 is the sidewall 2. When the tire is punctured to prevent deterioration of ride comfort and steering stability while the internal pressure of the tire decreases while the tread part 1 is lowered, the front end of the reinforcement rubber 4 rests on the catching jaw 5. While being caught, it is possible to prevent the continuous lowering operation of the tread part 1 so that the driving can continue even if there is no air pressure inside the tire.

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 평상시에는 보강고무의 강성이 사이드월의 강성에 영향을 주지 않다가 타이어의 펑크시에만 보강고무의 강성이 작용됨으로써 보강고무로 인한 승차감과 조종안정성을 불량함을 해소시킬 수 있는 효과가 있는 것이다.As described above, according to the present invention, the stiffness of the reinforcement rubber does not affect the stiffness of the sidewall at ordinary times, but the stiffness of the reinforcement rubber is applied only during the puncture of the tire, thereby eliminating the poor riding comfort and steering stability due to the reinforcement rubber. There is an effect that can be made.
