자동차용 타이어구조{A TIRE STRUCTURE OF CARS}Tire structure for automobiles {A TIRE STRUCTURE OF CARS}

본 발명은 자동차용 타이어구조에 관한 것으로서, 더욱 상세하게는 타이어가 펑크나거나 또는 바람이 급격히 빠질때 타이어가 자력의 반발력에 의해 변형되지 않도록 한 자동차용 타이어구조에 관한 것이다.The present invention relates to an automobile tire structure, and more particularly, to an automobile tire structure in which the tire is not deformed by the repulsive force of the magnetic force when the tire is punctured or the wind is rapidly dropped.

종래에 의한 자동차용 타이어구조는, 도1에 도시한 바와 같이, 노면과 직접 접촉되는 타이어(10)와, 상기 타이어(10)가 차륜에 회전가능케 지지하는 휠(20)로 구성되어 있다.The conventional tire structure for automobiles is composed of a tire 10 that is in direct contact with a road surface, and a wheel 20 that the tire 10 is rotatably supported on a wheel, as shown in FIG.

이때, 상기 타이어(10)는 그 일측에 설치된 공기주입용 튜브(도시안됨)를 통해 타이어(10)내에 주입되는 공기압에 의한 팽창력으로 소정의 형상을 유지하도록 되어 있다.At this time, the tire 10 is to maintain a predetermined shape by the expansion force by the air pressure injected into the tire 10 through the air injection tube (not shown) installed on one side.

그러나, 이와 같이 구성된 종래에 의한 자동차용 타이어구조는, 타이어(10)가 휠(20)에 끼워져 일정 공기압이 주입되어 사용되는 구조로 되어 있기 때문에 타이어(10)가 펑크나거나 압축공기에 의한 팽창력이 급격히 저하될때 차량이 한쪽으로 쏠리면서 전복되는 등의 대형사고의 위험이 있었다.However, in the conventional tire structure for automobiles configured as described above, since the tire 10 is fitted to the wheel 20 and a predetermined air pressure is injected thereto, the tire 10 is flat or inflated by compressed air. There was a risk of catastrophic accidents such as the vehicle tipping over and falling over when it was suddenly lowered.

또, 펑크난 타이어(10)를 교체하기 위하여 도시하지 않은 트렁크내에 스페어 타이어나 잭 등을 항상 갖추고 다녀야 하기 때문에 차량 중량 증대는 물론, 펑크난 타이어(10)를 폐품처리할때 환경이 오염된다는 문제점이 있었다.In addition, since spare tires or jacks must always be carried in the trunk (not shown) in order to replace the flat tire 10, the weight of the vehicle is increased, and the environment is polluted when the flat tire 10 is disposed of. There was this.

따라서, 본 발명은 상기 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 차량이 한쪽을 쏠려 전복되는 대형사고의 위험을 미연에 방지함과 동시에 별도의 스페어 타이어나 잭 등을 없애어 차량 중량을 감소시키고, 또 펑크난 타이어를 지속적으로 사용하여 환경 오염을 최소화시킬 수 있도록 한 자동차용 타이어구조를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to prevent the risk of large-scale accidents that the vehicle is overturned by one side, and at the same time to remove the spare tire or jack, and to remove the weight of the vehicle In addition, the present invention provides a tire structure for automobiles that minimizes environmental pollution by continuously using flat tires.

상기 목적을 달성하기 위하여 이루어진 본 발명에 의한 자동차용 타이어구조는, 노면과 직접 접촉되는 타이어와, 상기 타이어가 차륜에 회전가능케 지지하는 휠을 구비한 자동차용 타이어구조에 있어서, 상기 타이어의 내측 둘레를 따라 부착되는 다수의 영구자석과, 상기 휠의 외측 둘레를 따라 상기 다수의 영구자석과 대향되게 설치되며 또한 온 동작시 영구자석을 향해 자력을 발생하여 전자기적 반발력에 의해 타이어가 형상을 유지하도록 다수의 전자석과, 상기 휠의 외측 둘레면 일측에 설치되어 타이어내의 압축공기압을 감지하는 센서와, 상기 센서에서 감지신호를 받아 상기 다수의 전자석이 온/오프되게 제어하는 ECU를 포함함을 특징으로 한다.According to an aspect of the present invention, there is provided a tire structure for an automobile according to the present invention, comprising: a tire directly contacting a road surface and a wheel for supporting the tire to be rotatably supported on a wheel; A plurality of permanent magnets are attached along the circumference of the wheel, and are installed to face the plurality of permanent magnets along the outer circumference of the wheel, and also generate magnetic force toward the permanent magnet during on operation to maintain the tire shape by electromagnetic repulsive force. A plurality of electromagnets, a sensor installed at one side of the outer circumferential surface of the wheel to sense compressed air pressure in the tire, and an ECU controlling the plurality of electromagnets to be turned on / off by receiving a detection signal from the sensor do.

이하, 본 발명의 일실시예에 관하여 첨부 도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

참고로, 도면에서 종래의 구성과 동일한 구성에 대해서는 동일명칭 및 동일부호를 부여하고, 그에 대한 상세한 설명은 생략한다.For reference, the same components and the same reference numerals are assigned to the same components as the conventional components in the drawings, and detailed description thereof will be omitted.

본 발명에 의한 자동차용 타이어구조는, 도2에 도시한 바와 같이, 타이어(10)의 내측 둘레를 따라 일정간격을 두고 부착되는 다수의 영구자석(30)과, 상기 휠(20)의 외측 둘레를 따라 상기 다수의 영구자석(30)과 대향되게 설치되는 다수의 전자석(40)과, 상기 휠(20)의 외측 둘레에 대하여 일측에 설치되어 타이어(10)내의 압축공기압을 감지하는 센서(50)와, 차체(도시안됨)의 일측에 설치되어 상기 센서(50)에서 감지신호를 받아 상기 다수의 전자석(40)이 온/오프되도록 제어하는 ECU(Electronic Control Unit; 60)로 구성되어 있다.As shown in FIG. 2, the tire structure for automobiles according to the present invention includes a plurality of permanent magnets 30 attached to the tire 10 at regular intervals along the inner circumference of the tire 10, and the outer circumference of the wheel 20. A plurality of electromagnets 40 which are installed to face the plurality of permanent magnets 30 and the sensor 50 is installed on one side with respect to the outer circumference of the wheel 20 to sense the compressed air pressure in the tire 10 And an ECU (Electronic Control Unit) 60 installed on one side of the vehicle body (not shown) to control the plurality of electromagnets 40 to be turned on / off by receiving a detection signal from the sensor 50.

이때, 상기 다수의 영구자석(30)은, 상기 타이어(10)의 내측 둘레를 따라 일정간격을 두고 분할 배치됨과 동시에 폭방향을 따라 일전간격을 두고 분할 배치되어 있다.In this case, the plurality of permanent magnets 30 are dividedly arranged at regular intervals along the inner circumference of the tire 10 and at the same time, and are arranged at one interval along the width direction.

상기 다수의 전자석(40)은, 상기 휠(20)의 외측 둘레에 대하여 중앙에 오목하게 형성된 오목부(부호도시안됨)내에 삽입 고정되어 그 외측면과 휠(20)의 외측 둘레면이 동일한 수평을 이루도록 되어 있다.The plurality of electromagnets 40 are inserted into and fixed in recesses (not shown) which are formed concave in the center with respect to the outer periphery of the wheel 20 so that the outer surface and the outer periphery of the wheel 20 are the same horizontal. It is supposed to be.

상기 센서(50)는, 상기 타이어(10)와 휠(20)서 서로 접하는 내측부분에 대하여 휠(20)의 외측 둘레면 일측에 고정되어 있다.The sensor 50 is fixed to one side of the outer circumferential surface of the wheel 20 with respect to the inner portion of the tire 10 and the wheel 20 in contact with each other.

상기 ECU(60)는, 상기 다수의 전자석(40)과 센서(50)에 전자적(電子的)으로 연결되어 있다.The ECU 60 is electrically connected to the plurality of electromagnets 40 and the sensor 50.

이와 같이 구성된 본 발명의 타이어구조는, 차량 주행중 타이어(10)가 펑크나거나 또는 타이어(10)내의 압축공기압이 소정압력 이하로 감소될 경우, 도2에 도시한 바와 같이 타이어(10)의 내부에 대하여 휠(20)의 일측에 설치된 센서(50)가 압축공기압을 감지하여 ECU(60)에 데이타를 입력시켜 주게 되고, 이 ECU(60는 그 데이타를 판별하여 프로그램화된 입력에 따라 휠(20)의 외측 둘레면에 설치된 다수의 전자석(40)에 전류를 인가시킨다.The tire structure according to the embodiment of the present invention configured as described above has a structure inside the tire 10 as shown in FIG. 2 when the tire 10 is punctured or the compressed air pressure in the tire 10 is reduced below a predetermined pressure. The sensor 50 installed on one side of the wheel 20 detects the compressed air pressure and inputs data to the ECU 60. The ECU 60 determines the data and determines the data according to the programmed input. An electric current is applied to the plurality of electromagnets 40 installed on the outer circumferential surface of the backplane.

이때, 다수의 전자석(40)은 인가된 전류에 따라 강한 자력을 생성시킴으로써 타이어(10)의 내측 둘레면에 부착된 다수의 영구자석(30)과 도2에 표시한 점선화살표와 같이 전자기적 반발력을 일으키게 되고, 이로 인하여 타이어(10)는 형상이 변형되지 않고 주행이 가능한 형상을 유지하게 된다.At this time, the plurality of electromagnets 40 generate a strong magnetic force in accordance with the applied current, and a plurality of permanent magnets 30 attached to the inner circumferential surface of the tire 10 and electromagnetic repulsive force as shown by the dotted arrow shown in FIG. This causes the tire 10 to maintain a shape that can travel without deforming the shape.

이상 설명한 바와 같이, 본 발명에 의한 자동차용 타이어구조는, 타이어가 펑크나거나 압축공기에 의한 팽창력이 급격히 저하되어 압축공기압이 일정압 이하로 저하될때 자기부상력에 의해 타이어의 형상이 유지될 수 있도록 한 구조로 되어 있기 때문에 차량이 한쪽을 쏠려 전복되는 대형사고의 위험을 미연에 방지할 수 있음과 동시에 별도의 스페어 타이어나 잭 등을 없애어 차량 중량을 감소시키고, 또 펑크난 타이어를 지속적으로 사용하여 환경 오염을 최소화시킬 수 있는 효과가 있다.As described above, the tire structure for automobiles according to the present invention can maintain the shape of the tire by the magnetic levitation force when the tire is punctured or the expansion force caused by the compressed air is sharply lowered and the compressed air pressure is lowered below the predetermined pressure. The single structure prevents the risk of a large accident that the vehicle overturns on one side, and at the same time, reduces the weight of the vehicle by eliminating extra spare tires and jacks, and continuously uses flat tires. It has the effect of minimizing environmental pollution.
