Abstract

An apex less tire is provided that the weight of tire can be decreased since the domain corresponding to the height part is minimized. An apex less tire(100) comprises a tread(110), and a shoulder part(120) which is formed in the side of the thread and contacts to the bottom side with the rim flange(200) while having the bead(130). The shoulder portion comprises a rim protector(122) which is protruded to the width direction of the thread in order to protect the end part of the rim flange. The belt arranged at the lower part of the thread contacts with each other with bead. The carcass arranged at the lower part of the thread surrounds bead.

에이펙스리스 타이어{Apexless tire}Apexless tire

본 발명은 에이펙스리스 타이어에 관한 것으로, 더욱 상세하게는 타이어의 높이부(height section)에 해당하는 영역을 최소화함으로써 타이어의 중량을 감소시킬 수 있고 이로 인해 자동차의 연비를 개선할 수 있는 에이펙스리스 타이어에 관한 것이다.The present invention relates to an apexless tire, and more particularly, an apexless tire capable of reducing the weight of a tire by minimizing an area corresponding to a height section of the tire, thereby improving fuel efficiency of an automobile. It is about.

타이어가 발달하면서, 최근 UHP타이어와 런플랫 타이어에 관련된 기술이 많이 개발되고 있다.With the development of tires, many technologies related to UHP tires and run-flat tires have recently been developed.

특히, 종래기술의 런플랫(Run-Flat) 타이어는 보강고무 삽입 등을 통해 사이드월 부분을 보강하거나, 휠 부분에 타이어를 지지할 수 있는 인서트(insert)를 넣어 그 성능을 나타내었다.In particular, the run-flat tire of the prior art exhibits its performance by reinforcing the sidewall portion through reinforcement rubber insertion or inserting an insert into the wheel portion to support the tire.

이로 인해 타이어의 중량이 크게 증가 되었다. 따라서, 자동차의 연비가 저하되는 문제점이 있다.This greatly increased the weight of the tire. Therefore, there is a problem that the fuel economy of the automobile is lowered.

상기의 문제점을 해결하기 위해 안출된 본 발명의 목적은, 높이부(height section)에 해당하는 영역을 최소화함으로써 타이어의 중량을 감소시킬 수 있고 이로 인해 자동차의 연비를 개선할 수 있는 에이펙스리스 타이어를 제공하는 데에 있다.An object of the present invention devised to solve the above problems is to reduce the weight of the tire by minimizing the area corresponding to the height (height section), thereby reducing the apex tires that can improve the fuel economy of the vehicle To provide.

상기의 목적을 달성하기 위한 본 발명은, 트레드; 및 상기 트레드의 측부에 형성되고 하측에 비드를 가지며 림플랜지와 접하는 숄더부를 포함하는 것을 특징으로 하는 런플랫 타이어이다.The present invention for achieving the above object, a tread; And a shoulder portion formed on the side of the tread and having a bead on the lower side and in contact with the rim flange.

상기 숄더부는 상기 림플랜지의 단부를 보호하도록 상기 트레드의 폭방향으로 돌출되는 림프로텍터가 형성되는 것을 특징으로 한다.The shoulder portion is characterized in that the lymph rotator protruding in the width direction of the tread so as to protect the end of the rim flange.

또, 상기 트레드 하부에 배치되는 벨트는 상기 비드와 맞닿는 것을 특징으로 한다.In addition, the belt disposed under the tread is characterized in that the contact with the bead.

또, 상기 트레드 하부에 배치되는 카카스는 상기 비드를 감싸는 것을 특징으로 한다.In addition, the carcass disposed under the tread is characterized in that it wraps the bead.

본 발명을 통하여 런플랫 타이어의 성능을 유지하면서, 타이어의 중량을 감 소시킬 수 있다.The present invention can reduce the weight of the tire while maintaining the performance of the run flat tire.

또한, 이러한 장점과 동시에 UHP의 장점을 갖는 타이어를 생산함으로써 다양한 성능을 동시에 추구하는 소비자의 구매 촉진을 유도할 수 있다. In addition, by producing a tire having the advantages of the UHP simultaneously with these advantages, it is possible to promote the purchase of consumers who pursue a variety of performance at the same time.

그리고, 에이펙스와 사이드 월을 제거함으로써 중량 및 원가를 절감하고 제조 공정을 단순화할 수 있다.And by eliminating apex and sidewalls, weight and cost can be reduced and manufacturing processes can be simplified.

이하, 본 발명을 바람직한 실시예를 첨부한 도면을 참조하여 설명하기로 한다. 하기의 각 도면의 구성 요소들에 참조 부호를 부가함에 있어서, 동일한 구성 요소들에 한해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하며, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기능 및 구성에 대한 상세한 설명은 생략한다. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described. In adding reference numerals to components of the following drawings, it is determined that the same components have the same reference numerals as much as possible even if displayed on different drawings, and it is determined that they may unnecessarily obscure the subject matter of the present invention. Detailed descriptions of well-known functions and configurations will be omitted.

본 발명은 높이부(height section)에 해당하는 영역을 최소화함으로써 런플랫(Run-Flat) 기능을 추구하는 동시에 중량 감소를 이룰 수 있도록 하는 것이 요지이다. The present invention is directed to minimizing the area corresponding to the height section so as to achieve a run-flat function and achieve weight reduction.

도 1은 본 발명의 실시예에 따른 런플랫 타이어(100)의 부분단면도로써, 림플랜지(Rim flange)(200)와 트레드(110) 영역이 바로 접하는 타이어(100)를 도시하고 있다.1 is a partial cross-sectional view of a run flat tire 100 according to an exemplary embodiment of the present invention, and illustrates a tire 100 directly contacting a rim flange 200 and a tread 110 region.

따라서, 상기 타이어(100)는 트레드(100)의 양단부에 위치하는 숄더부(120)의 하부에 림플랜지(200)의 하중을 받기 위한 비드(130)가 배치된다.Accordingly, the tire 100 has a bead 130 for receiving the load of the rim flange 200 is disposed in the lower portion of the shoulder 120 located at both ends of the tread (100).

그리고, 상기 트레드(100) 내에 배치되는 벨트(112)는 상기 비드(130) 근처 또는 상기 비드(130)와 닿도록 연장되어, 상기 비드(130)를 통해 부과되는 하중이 상기 벨트(112)를 통해 전달되도록 하여, 종래기술에 에이펙스의 역할을 대체하도록 한다.In addition, the belt 112 disposed in the tread 100 extends near or in contact with the bead 130, such that a load imposed through the bead 130 is applied to the belt 112. To be transmitted through, to replace the role of Apex in the prior art.

그리고, 상기 숄더부(120)는 상기 림플랜지(200)의 단부를 보호하도록 상기 트레드(110)의 폭방향으로 돌출되어 형성되는 것이 바람직하다. In addition, the shoulder portion 120 is preferably formed to protrude in the width direction of the tread 110 to protect the end of the rim flange 200.

즉, 상기 숄더부(120)의 일측에 상기 트레드(110)의 외측방향으로 림프로텍터(122)가 형성된다.That is, the lymph rotator 122 is formed at one side of the shoulder 120 in the outward direction of the tread 110.

또한, 상기 림프로텍터(122)는 상기 비드(130)와 함께 하중을 받을 수 있어서, 진동흡수에 유리하게 된다.In addition, the lymph rotator 122 may be loaded with the bead 130, it is advantageous to absorb the vibration.

또한, 상기 트레드(110) 내부의 카카스는 상기 숄더부(120)를 거쳐 상기 비드(130)를 감싸 턴업되도록 한다.In addition, the carcass inside the tread 110 is wrapped around the bead 130 through the shoulder portion 120 to be turned up.

따라서, 본 발명은 높이부가 없어 타이어의 굴신이 없으므로 런플랫 타이어(Run-Flat tire)의 성능도 함께 나타낼 수 있다. Therefore, the present invention can exhibit the performance of the run-flat tire because there is no height and there is no flexion of the tire.

상기와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만 해당 기술 분야의 숙련된 당업자라면 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다. As described above, it has been described with reference to the preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
