Abstract

The present invention relates to a tire having a structure that can be used without injecting air into a vehicle tire and a method for manufacturing the same. A coil spring with strong elasticity and rigidity is made in a circle shape in addition to a conventional tire and placed inside the tire. The tire formed like this is mounted on a vehicle wheel to be used. The coil spring in a circular shape state positioned within the tire, if the tire is mounted in the vehicle to be used, transfers a load, applied to the tire, to the entire circular coil spring to distribute the load and is capable of regularly maintaining, on the tire, the load of a portion in contact with the ground while the wheel rotates. In addition, since air is not injected, even if a puncture occurs while driving, a flat tire problem does not occur to prevent accidents and further increase safety of a driver. In addition, since the coil spring in a circular shape can be easily inserted into an existing (prior art) tire to be used, separate air injection is not required, and if necessary, the tire can be used without air injection even in a state in which the spring in a circular shape is inserted such that a tire safety level and riding comfort can be maintained without a change.

Description

공기 없는 타이어 및 그 제조 방법{Airless Tire and Manufacturing this}Airless Tire and Manufacturing this

종래 기술에서, 차량용 타이어는 바퀴(wheel)에 타이어를 장착한 후 공기를 주입하여 타이어 내부에 공기를 가둔 상태에서 사용하게 되어 있다. 즉, 종래기술의 타이어는 타이어 내부와 바퀴의 림(Rim) 사이에 공기를 주입하여 사용할 수 있는 구조이다. 종래기술의 타이어는 그 형태가 (도5 )와 같이,In the prior art, a vehicle tire is used in a state in which air is trapped inside the tire by injecting air after the tire is mounted on a wheel. That is, the prior art tire has a structure that can be used by injecting air between the inside of the tire and the rim of the wheel. The tire of the prior art has a shape as shown in (FIG. 5),

-트래드(Tread)(1) -사이드월(Side-Wall)(2) -타이어측면(3)-Tread(1) -Side-Wall(2) -Tire side(3)

-비드(Bead)(4) -타이어 내부(Tire-Inside)(7)-Bead(4) -Tire-Inside(7)

등으로 되어 있다.and so on.

종래기술로 이루어져 있는 타이어를 차량의 바퀴에 장착하여 사용하는 경우 (도4) (도5)와 (도6)에서, 타이어를 바퀴(Wheel)(9)의 림(Rim)(8)에 맞추고, 바퀴에 있는 공기 주입구를 사용하여 공기를 주입하고, 압력을 조절하여 림(Rim)(8)과 비드(Bead)(4)가 밀착되어 주입된 공기가 밀폐된 상태에서 사용하게 된다. 이러한 상태에서는 공기로 인한 차량 승차감은 좋을 수 있으나, 차량이 고속주행 중 타이어에 펑크(Puncture)가 발생할 경우 차량이 전복되는 등 큰 사고를 유발할 수 있게 된다. 또한 차량의 하중과 주행 중 발생하는 충격 등을 타이어 측면(3)이 충분히 견딜 수 있도록 하기 위하여 측면에 재질 및 구조적으로 안전한 형태의 카커스(Carcass)를 제작하는 등... 타이어를 제조하는 비용이 증가하게 된다.In the case of using a tire made of the prior art mounted on the wheel of a vehicle (FIG. 4) (FIG. 5) and (FIG. 6), the tire is aligned with the rim (8) of the wheel (9) and , the air is injected using the air inlet on the wheel, and the pressure is adjusted so that the rim (8) and the bead (4) are in close contact and the injected air is used in a sealed state. In this state, the ride comfort due to air may be good, but if a puncture occurs in a tire while the vehicle is driving at high speed, it may cause a serious accident such as overturning of the vehicle. In addition, in order for the tire side 3 to sufficiently withstand the load of the vehicle and the impact generated during driving, a carcass of a material and structurally safe form is manufactured on the side surface, etc. Cost of manufacturing a tire this will increase

종래기술의 타이어를 사용하여, 차량바퀴에 이를 장착하고 공기를 주입하여 사용하게 된다. 이때 차량이 도로를 주행 중 펑크가 발생하면 타이어가 주저 앉아 주행이 불가능하게 된다. 또한 고속 주행 중에 타이어에 펑크가 날 경우는 차량이 전복될 수 있는 큰 사고로 이어질 수 있다.By using a tire of the prior art, it is mounted on a vehicle wheel and used by injecting air. At this time, if a puncture occurs while the vehicle is driving on the road, the tire will sit down, making it impossible to drive. Also, if a tire punctures while driving at high speed, it may lead to a serious accident in which the vehicle may overturn.

본 발명은 위에서 언급한 문제점들을 해결하면서, 타이어에 공기를 주입하지 않고 차량바퀴에 장착하여 사용할 수 있으며, 또한 타이어 구조를 개선하여 타이어 제조 시 원가를 줄일 수 있도록 할 수 있다The present invention solves the above-mentioned problems and can be used by being mounted on the wheel of a vehicle without injecting air into the tire, and can also reduce the cost of manufacturing the tire by improving the tire structure.

본 발명은, 종래기술로 이루어지는 타이어에 공기를 주입하여 사용하는 것에서 벗어나, 공기 대신 강성과 탄성(Stiffness, Rigidity & Elasticity)을 갖는 코일스프링(Coil-Spring)을 타이어 공간의 크기와 또한 이를 장착하는 바퀴(Wheel)의 림(Rim) 원주(Circumference of Rim)를 고려하여 원형(Circle Type)으로 만들어, 이를 타이어 안쪽에 위치하게 한 후, 타이어를 바퀴에 장착하여 사용하도록 한다.The present invention, away from injecting air into a tire made of the prior art, and using a coil spring having stiffness and elasticity (Stiffness, Rigidity & Elasticity) instead of air, the size of the tire space and also mounting it Considering the circumference of the rim of the wheel, make it a circle type, place it inside the tire, and then use it by attaching the tire to the wheel.

본 발명은 공기(Air, Gas)를 주입하여 사용하는 종래기술의 타이어에 비해,The present invention is compared to the tire of the prior art which is used by injecting air (Air, Gas),

-공기를 주입하지 않고 타이어를 사용할 수 있어, 차량 주행 시 발생할 수 있는 펑크로 인한 타이어의 주저 앉음을 방지할 수 있다.- Since the tire can be used without injecting air, it is possible to prevent the tire from settling down due to a puncture that may occur while driving a vehicle.

-타이어 몸통 등에 대한 재질 및 구조를 개선하여 보다 안정적인 타이어 제조를 통해 타이어 제조비용을 줄일 수 있다.- By improving the material and structure of the tire body, it is possible to reduce the tire manufacturing cost through more stable tire manufacturing.

-종래기술의 타이어 내부에 원형의 코일스프링을 위치하게 한 후, 필요시 공기를 주입하여 사용함으로써 승차감과 안전성을 동시에 유지할 수 있다.- After placing the circular coil spring inside the tire of the prior art, it is possible to maintain ride comfort and safety at the same time by injecting air when necessary.

따라서, 본 발명의 원형의 코일스프링을 타이어 내부(몸통 안쪽)에 위치하게 제작한 후, 이를 차량에 장착하여 사용함으로써 타이어 펑크로 인한 사고를 방지할 수 있다.Therefore, it is possible to prevent an accident due to a tire puncture by manufacturing the circular coil spring of the present invention to be positioned inside the tire (inside the body) and then using it by mounting it on a vehicle.

본 발명은, 종래 기술의 타이어를 차량에 장착하여 공기를 주입하여 사용하는 데 따른 문제점을 해결함으로써 타이어의 안전도를 향상시키고자 하는데 있다.An object of the present invention is to improve the safety of the tire by solving the problem of using the prior art tire by injecting air into the vehicle.

강성과 탄성을 갖는 코일스프링(Coil-Spring)을 원형으로 형성한다(도2). 이때 타이어 몸통 내부에 정확하게 위치할 수 있도록, 코일스프링의 지름과 코일스프링을 원형으로 형성할 때 크기(지름,원주)를 조절한다. 그리고, 원형으로 형성된 코일스프링을 타이어 몸통 내부에 삽입하여 위치토록 한다(도1).A coil spring having rigidity and elasticity is formed in a circular shape (FIG. 2). At this time, the diameter of the coil spring and the size (diameter, circumference) are adjusted when forming the coil spring in a circle so that it can be accurately positioned inside the tire body. Then, a coil spring formed in a circular shape is inserted into the tire body to position it (FIG. 1).

원형의 코일스프링이 삽입되어 있는 형태의 타이어를 차량 바퀴에 장착하여 사용한다.A tire with a circular coil spring inserted therein is used by attaching it to the wheel of a vehicle.

이때, 타이어 몸통 내부에 위치하고 있는 코일스프링과 타이어의 비드(Bead)와 바퀴의 림(Rim)이 서로 상대적으로 힘을 받을 수 있도록, 코일스프링 재질(Material)과 굵기와 형태(Shape)를, 그리고 코일스프링으로 형성한 원형 스프링의 형태(Shape)를 다양하게 할 수 있다(도4).At this time, the coil spring material, thickness and shape are selected so that the coil spring located inside the tire body, the tire bead, and the wheel rim can receive relative force to each other, and The shape of the circular spring formed by the coil spring can be varied (FIG. 4).

또한, 본 발명의 기술로 이루어진 타이어를 장착하여 사용하는 바퀴(Wheel)의 경우, 바퀴의 림(Rim)과 타이어의 비드(Bead)가 서로 밀착되는 부분에 비드 또는 림 부분에 미세 틈새(Slit,Sipe)를 형성하여 타이어의 눌림과 이완 등에 따른 타이어 내부 공기가 외부와 자연스럽게 이동(흡입과 배출)이 이루어 질 수 있게 하여, 차량 주행 시 타이어의 형태를 안정적으로 유지할 수 있게 한다.In addition, in the case of a wheel used by mounting a tire made of the technology of the present invention, a bead or a fine gap (Slit, Sipe) is formed so that the air inside the tire can move naturally (suction and exhaust) with the outside according to the pressing and loosening of the tire, so that the shape of the tire can be stably maintained while the vehicle is driving.
