스톤이젝터 보강용 돌출부를 가진 공기입 타이어{PNEUMATIC TIRE HAVING STONE-EJECTOR REINFORCED WITH PREJECTED MEMBER}PNEUMATIC TIRE HAVING STONE-EJECTOR REINFORCED WITH PREJECTED MEMBER}

본 고안은 공기입 타이어의 그루브에 형성되는 스톤이젝터와 이 보강하기 위한 보강용 돌출부에 관한 것이다.The present invention relates to a stone ejector formed in the groove of a pneumatic tire and a reinforcing protrusion for reinforcing.

공기입 타이어의 일반적인 단면구조는, 지면과 접촉하는 트레드와, 상기 트레드를 밑에서 지지하는 카카스와, 타이어의 측면을 이루는 사이드월과, 트레드와 사이드월이 만나는 지점의 숄더 그리고, 휠에 밀착되는 지점에 카카스의 양단이 접어 올려 형성된 림으로 형성된다.The general cross-sectional structure of a pneumatic tire includes a tread in contact with the ground, a carcass supporting the tread from below, a sidewall forming the side of the tire, a shoulder at the point where the tread meets the sidewall, and a point of close contact with the wheel. Both ends of the carcass is formed in the rim formed by folding.

상기 트레드에는 가로방향과 세로방향으로 홈이 복수 형성되어 이를 그루브라 하며 상기 트레드의 면은 그루브에 의해 구획이 나뉘어지며 이러한 구획들을 트레드 블록이라 한다. 상기 그루브는 타이어 원주방향으로 연속적으로 연장형성된 종그루브와, 상기 종그루브 사이를 교차하면서 경사지게 형성된 횡그루브가 있으며, 상기 그루브의 일반적인 역할은, 트레드 블록 형성에 의한 트랙션(traction)을 이용한 조정력 향상과 도로면의 물에 대한 타이어 접지면 바깥방향으로의 배수촉진과, 접지 노이즈 분산 그리고, 트레드 마모정도를 알 수 있도록 하는 인디케이터로 서의 작용을 가지고 있다. 그리고, 그루브의 저면에는 스톤이젝터가 돌출형성되어 그루브 속으로 돌과 같은 딱딱한 이물질이 끼어 조향력을 저해하는 불순물을 배제하도록 되어 있다.The tread has a plurality of grooves formed in a horizontal direction and a vertical direction to groove the tread, and the tread surface is divided by grooves, and these sections are called tread blocks. The groove includes a longitudinal groove extending continuously in the circumferential direction of the tire, and a horizontal groove formed to be inclined while crossing between the longitudinal grooves, and the general role of the groove is to improve adjustment force using traction by forming a tread block. It serves as an indicator to promote drainage of the road surface to the outside of the tire ground plane, distribution of ground noise, and tread wear. In addition, a stone ejector protrudes from the bottom of the groove so that hard foreign substances such as stones are inserted into the groove to remove impurities that hinder steering power.

도 6 및 도 7은 종래의 스톤이젝터를 도시한 부분 사시도이다.6 and 7 are partial perspective views showing a conventional stone ejector.

도 6은 스톤이젝터 기능 외에 타이어(10)가 일정한 마모 수준에 도달하게 되면 홈(5)이 드러나게 되어 사용자가 리그루빙시기를 손쉽게 결정할 수 있도록 한 것이고, 도 7 또한, 스톤이젝터(2')에 홈(5)이 형성되어 그 홈(5)이 드러나게 되면 사용자가 리그루빙 시기를 알게 되는 것이다. 이와 같이 종래에는 스톤이젝터 기능과 함께 리그루빙 시기를 결정하는데 도움을 주는 구조로 사용되었지만, 트레드 블록 마모에 따른 트랙션 성능의 저하에 따른 문제점은 전혀 고려되어 있지 않다. 그리고, 스톤이젝터의 형상설계는 그루브의 형상과 관련해서 설계해야 하는 불편함이 있었다.FIG. 6 shows that the groove 5 is exposed when the tire 10 reaches a certain level of wear in addition to the stone ejector function, so that the user can easily determine the relubricating time, and FIG. 7 also shows the stone ejector 2 '. When the groove 5 is formed and the groove 5 is revealed, the user knows the time of the rig rubbing. As such, in the related art, the stone ejector function is used as a structure that helps to determine the relubrication time, but the problem due to the decrease in the traction performance due to the tread block wear is not considered at all. And, the shape design of the stone ejector had to be inconvenient to design in relation to the shape of the groove.

본 고안은 상술한 문제점을 해결하기 위해 안출된 것으로, 스톤이젝터의 돌끼임 방지 역할을 극대화하는 동시에, 그루브의 형상과 관계없이 스톤이젝터의 형상설계를 독립적으로 행할 수 있고, 또한, 트레드 블록의 마모에 따른 트랙션 저하를 방지할 수 있도록 하는데에 그 목적이 있다. The present invention has been devised to solve the above-described problems, while maximizing the stone ejector's prevention of crushing, and independently designing the shape of the stone ejector irrespective of the shape of the groove, the wear of the tread block is also possible. The purpose is to be able to prevent the traction degradation caused by.

본 고안은 타이어의 그루브에서 그 경사면을 따라 트레드 블록면에 대해 일 정 각도로 기울어져서 그루브 저면에까지 일정폭으로 연장되는 스톤이젝터 보강용 돌출부를 구비한다.The present invention includes a stone ejector reinforcement protrusion which is inclined at a predetermined angle with respect to the tread block surface along the slope of the groove of the tire and extends to the groove bottom.

타이어 그루브에 형성되는 스톤이젝터의 돌끼임 방지 역할을 극대화하는 동시에, 그루브의 형상과 관계없이 스톤이젝터의 형상설계를 독립적으로 행할 수 있고, 또한, 트레드 블록의 마모에 따른 트랙션 저하를 방지할 수 있는 탁월한 효과가 있다.In addition to maximizing the role of stone ejectors formed in the tire grooves, it is possible to independently design the shape of the stone ejectors irrespective of the shape of the grooves, and to prevent the traction deterioration due to the wear of the tread block. Excellent effect

본 고안에 따른 바람직한 실시예에서는, 상기 그루브(20) 내부에 형성된 스톤이젝터(2)의 폭(t)은, 그루브(20)의 폭(W)을 1로 하였을 때, 0.1≤t≤0.4 의 범 위로 하였고, 상기 스톤이젝터 보강용 돌출부(1)의 설치각도(A)는 트레드블록면(4)에 대해 30≤A≤90 내로 하였다. 또한 상기 스톤이젝터 보강용 돌출부(1)의 돌출 폭(w')은 그루브의 폭(W)을 1로 하였을 때 0.1≤w'≤0.3 내로 하였고, 스톤이젝터 보강용 돌출부 간의 피치(p')는 스톤이젝터 간의 피치(P)와 동일하다.In a preferred embodiment according to the present invention, the width t of the stone ejector 2 formed in the groove 20 is 0.1≤t≤0.4 when the width W of the groove 20 is 1. The installation angle A of the stone ejector reinforcement protrusion 1 was set to 30 ≦ A ≦ 90 with respect to the tread block surface 4. In addition, the protrusion width w 'of the stone ejector reinforcement protrusion 1 was 0.1 ≦ w' ≦ 0.3 when the width W of the groove was 1, and the pitch p 'between the protrusions of the stone ejector reinforcement was It is equal to the pitch P between the stone ejectors.

상기와 같은 수치한정의 근거로서, 돌과 같은 딱딱한 불순물이 타이어의 그루브로 끼워지면서 끼워진 상태가 유지되지 않고 도로면 마찰의 새로운 국면에서 불순물의 하중 및 원심력에 의해 용이하게 제거됨을 확인하는 과정에서 얻어진 실험치로서, 상기 각 수치한정 구간 중 하한치는 화물용 등 타이어의 직경이 비교적 큰 타이어에 적용하는 것이 바람직하며, 상한치는 승용차용 타이어 등 비교적 타이어의 직경이 작은 타이어에 적용됨이 바람직하다.As a basis for the numerical limitation as described above, it is obtained in the process of confirming that hard impurities such as stones are easily removed by the load and centrifugal force of impurities in a new phase of road surface friction without being held in the state of being fitted into the groove of the tire. As an experimental value, the lower limit of each numerical limit section is preferably applied to a tire having a relatively large diameter of a tire such as a cargo, and the upper limit is preferably applied to a tire having a relatively small diameter such as a tire for a passenger car.

본 고안에 의하면, 차량 주행시 타이어의 그루브에 끼이게 되는 돌과 같은 딱딱한 불순물이 용이하게 그루브 밖으로 제거되며, 스톤이젝터의 형상설계시 그루브의 형상과 관계없이 독립적으로 설계변경이 가능해지며, 한편으로 타이어의 트레드가 마모되더라도 스톤이젝터 보강용 돌출부의 단면적 만큼 트레드 블록의 접지면적이 늘어나므로, 트랙션이 향상되어 접지성능의 저하를 줄일 수 있게 된다.According to the present invention, hard impurities such as stones, which are caught in the grooves of the tire when the vehicle is driven, are easily removed from the grooves, and when the shape of the stone ejector is designed, the design can be changed independently regardless of the shape of the grooves. Even if the tread of the tread is worn out, the ground area of the tread block is increased by the cross-sectional area of the protrusion of the stone ejector reinforcement, so that the traction is improved to reduce the degradation of the grounding performance.
