Description

자동차용 공기입 타이어{Pneumatic tire for vehicle}Pneumatic tire for vehicle

본 발명은 자동차용 공기입 타이어에 관한 것으로서, 더욱 상세하게는 타이어가 장착되는 림과 타이어의 비드부사이에서 발생되는 슬립 현상을 억제시켜 조종 안정성을 향상시킴과 아울러 자동차의 급선회동작 및 급 제동시에 발생될 수 있는 사고를 미연에 방지할 수 있게 하는 자동차용 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire for a vehicle, and more particularly, to suppress the slip phenomenon generated between the rim on which the tire is mounted and the bead portion of the tire to improve steering stability, and to occur during rapid turning and braking of the vehicle. It relates to a pneumatic tire for a vehicle that can prevent possible accidents in advance.

일반적으로 림에 결합되는 타이어는 림에 견고하게 결합되어 서로 미끄러짐이 발생하지 않아야 한다.In general, tires coupled to the rim should be firmly coupled to the rim so that they do not slip together.

특히 자동차의 주행 도중에 자동차가 급선회를 한다던 지 급발진 또는 급정거를 하는 경우에 있어서 림과 타이어가 그 접촉면에서 서로 미끄러지게 되면 타이어가 림 주위를 겉돌게 되어 차량의 구동력이나 제동력이 타이어에 전달되지 못하게 되며 따라서 매우 위험한 상황이 발생할 염려가 있음과 아울러 타이어 내부에 충전된 공기가 누출되는 문제점이 발생하게 되는 것이다.Particularly, when the vehicle makes a sharp turn or sudden start or stop while driving, if the rim and tire slip on each other at the contact surface, the tire will move around the rim and the driving or braking force of the vehicle will not be transmitted to the tire. Therefore, there is a risk that a very dangerous situation may occur, and the problem of leaking the air filled inside the tire will occur.

따라서 본 출원인은 상기한 바와 같은 문제점을 해결하고자 타이어의 비드부와 림과의 사이에 미끄러짐을 방지할 수 있도록 하는 자동차용 바퀴(대한민국 실용신안 등록 출원 제 97-11243호)를 제공한바 있다.Accordingly, the present applicant has provided an automobile wheel (Korean Utility Model Registration Application No. 97-11243) which can prevent slippage between the bead portion of the tire and the rim to solve the above problems.

상기 본 출원인의 선 출원 발명은 림과 타이어 비드부의 접면에 요철결합부를 형성시켜 림과 타이어 접면의 기밀성을 제공함과 동시에 림과 타이어가 원주 방향으로 서로 미끄러지지 않도록 하여 선회 성능과 제동 성능을 향상시킬 수 있도록구성된 것이다.The applicant's prior application of the present invention provides an airtightness between the rim and the tire contact surface by forming a concave-convex coupling portion at the contact surface of the rim and the tire bead, and at the same time prevents the rim and the tire from slipping in the circumferential direction, thereby improving turning performance and braking performance. It is configured to.

그러나 상기한 선 출원 발명에 따른 바퀴를 제작하고 이를 실 차에 장착하여 시험 주행하는 과정에서 림과 타이어 접면부 사이의 기밀성은 크게 향상되었으나 림과 타이어 비드와의 결합력 향상은 기대한 만큼 향상되지 못하였음을 알게 되었다.However, the airtightness between the rim and the tire contact portion was greatly improved in the process of manufacturing the wheel according to the above-described invention and mounting it on the actual vehicle, but the improvement of the binding force between the rim and the tire bead was not improved as expected. I found out.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 비드부와 림과의 결합력을 증대시켜 림과 타이어의 비드부사이에서 발생되는 슬립 현상 발생을 방지하여 승차감(차량의 이상진동 방지)을 향상시킴과 아울러 자동차의 급선회동작 및 급제동시에 발생될 수 있는 사고를 미연에 방지할 수 있게 하는 자동차용 공기입 타이어를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the present invention is to increase the bonding force between the bead portion and the rim to prevent the slip phenomenon generated between the rim and the bead portion of the tire ride comfort (prevention of abnormal vibration of the vehicle) The present invention also aims to provide a pneumatic tire for a vehicle that can prevent accidents that may occur during rapid turning and braking of a vehicle in advance.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 즉, 본 발명은 차량에 장착되는 림과, 림에 장착되는 타이어의 비드부 접면사이에 미끄럼 방지 수단을 형성시킴에 있어서, 상기 미끄럼방지수단이 자력의 힘으로 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, the present invention is characterized in that the non-slip means is formed of a magnetic force in forming a non-slip means between the rim mounted on the vehicle and the contact surface of the bead portion of the tire mounted on the rim.

도 1 내지 도 3 에 도시된 바와 같이 본 발명은 차량에 장착되는 림(1)과, 상기 림에 장착되는 타이어의 비드부(2) 접면사이에 미끄럼 방지 수단을 형성시킴에 있어서, 상기 미끄럼방지수단을 자력의 힘을 이용한 것에 관한 것이다.As shown in Figs. 1 to 3, the present invention provides a non-slip in forming a non-slip means between the rim 1 mounted on the vehicle and the contact surface of the bead portion 2 of the tire mounted on the rim. It is about using the means of magnetic force.

자력의 힘으로 타이어의 비드부(2)와 림(1)과의 결합력을 증대시키기 위하여 본 발명에서는 림(1)에 접촉되는 비드베이스(20)면을 자성체(21)로 형성시키고, 비드베이스(20)와 접하는 림(1)을 자석으로 형성시켜 구성된다.In the present invention, in order to increase the bonding force between the bead portion 2 and the rim 1 of the tire by the force of the magnetic force, the surface of the bead base 20 in contact with the rim 1 is formed of a magnetic body 21, and the bead base The rim 1 which is in contact with 20 is formed by forming a magnet.

비드베이스(20)면을 자성체(21)로 형성시킴에 있어서는 비드베이스(20)면의 고무조성물에 강한 자성체 분말을 혼합시켜 구성한다.In forming the bead base 20 surface by the magnetic body 21, it is comprised by mixing strong magnetic powder with the rubber composition of the bead base 20 surface.

이와 같은 방법은 고무자석의 제조방법과 동일한 것이다.This method is the same as the manufacturing method of the rubber magnet.

그리고 상기 림(1)을 자석화 시킴에 있어서는 이를 전자석으로 형성시키는 것이 바람직하며, 본 발명은 비드베이스(20)가 접합는 림(1)의 저부에 전자석(3)을 설치시키고, 상기 전자석(3)에 전원을 연결시켜 구성하였다.In the magnetization of the rim 1, it is preferable to form it as an electromagnet, and the present invention provides an electromagnet 3 at the bottom of the rim 1 to which the bead base 20 is bonded, and the electromagnet 3 ) To the power source.

상기 전자석(3)에 전원을 연결시킴에 있어서는 림(1)이 회전체임에 따라 전원을 림(1)에 직접연결시키지 아니하고 간접적으로 전원을 공급시킬 수 있게 구성한다.In connecting the power source to the electromagnet 3, the rim 1 is configured to be able to supply power indirectly without directly connecting the power source to the rim 1 as the rim 1 is a rotating body.

간접적으로 전원을 공급시키기 위하여 본 발명은 림(1)의 원주방향으로 전자석(3)과 연결되는 와이어(30)를 설치시키고, 림(1)에 근접하는 위치에 고주파전류발생기(4)를 설치시켜 구성하였다.In order to supply power indirectly, the present invention installs a wire 30 connected to the electromagnet 3 in the circumferential direction of the rim 1, and installs a high frequency current generator 4 at a position proximate to the rim 1. It was configured to.

고주파전류발생기(4)에 전원이 인가되면 림(1)에 설치된 와이어에 유도기전류가 발생되고, 이 전류는 전자석(3)에 전달되어 전자석이 자력을 발생시키게 되는 것이다.When power is applied to the high frequency current generator 4, an inductor current is generated in the wire installed in the rim 1, and this current is transmitted to the electromagnet 3, which causes the electromagnet to generate magnetic force.

그리고 상기 고주파전류발생기(4)로의 전원 공급을 제어하는 스위치(40)를 브레이크페달(5)과 연결시켜 브레이크페달(5)의 밟음 동작시에만 스위치(40)가 온(on)되어 전자석(3)이 자력을 발생시킬 수 있게 구성시킬 수도 있다.Then, the switch 40 for controlling the power supply to the high frequency current generator 4 is connected to the brake pedal 5 so that the switch 40 is turned on only when the brake pedal 5 is stepped down and the electromagnet 3 ) Can be configured to generate magnetic force.

이와 같이 구성되는 본 발명은 차량의 주행과정에서 브레이크페달(5)을 밟게 되면 스위치(40)가 온되어 고주파전류발생기(4)에 전원이 통전되고, 와이어(30)에 유도기전류가 발생되며 이 전류는 전자석(3)에 전달되어 전자석이 자력을 발생시키게 된다.According to the present invention configured as described above, when the brake pedal 5 is pressed in the driving process of the vehicle, the switch 40 is turned on so that power is supplied to the high frequency current generator 4, and an inductor current is generated in the wire 30. The electric current is transmitted to the electromagnet 3 so that the electromagnet generates a magnetic force.

전자석(3)에서 발생되는 자력에 의해 비드베이스(20)에 형성된 자성체(21)가 자력의 힘에 이끌러 림(1)에 견고하게 밀착되어 슬립발생을 억제시키게 되는 것이다.The magnetic body 21 formed on the bead base 20 by the magnetic force generated by the electromagnet 3 is firmly adhered to the rim 1 by the force of the magnetic force to suppress the occurrence of slip.

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 림과 타이어의 접면부에 있어서, 그 기밀성 뿐만이 아니라 결착성 또한 향상시켜 자동차의 선회 성능과 제동 성능을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, there is an effect of improving the turning performance and the braking performance of the vehicle by improving not only the airtightness but also the binding property at the contact portion of the rim and the tire.
