Abstract

A wheel for a vehicle having an expansion flange is provided to extend contact pressure generated between an expansion flange and a side wall part of a tire in charge of inner pressure in the tire by increasing adhesiveness of the expansion flange with the tire. A curved part(2) shaped as an expansion flange(1) is formed at a straight line(Lm) contacted to an expansion radius(Re) of the flange with a radius(R2) of the flange, and at a radius(Rm) contacted to the radius of the flange to be vertically contacted to the expansion radius. The expansion height of the flange is within section height of a tire of 60 percentages. The maximum width(We) of inner/outer sides in the expansion flange is determined within nominal section width of the tire of Œ2 percentages. The radius of the curved part is contacted with the radius of the flange. The straight line is contacted with the expansion radius of the flange. The radius and the straight line are connected to each other. The contact point of the radius and the straight line is within the expansion height of the flange of 20 to 75 percentages.

본 발명은 타이어를 장착하는 자동차용 휠에 관한 것으로, 더욱 상세하게는 타이어에 내압충전 및 하중 작용시 타이어와 휠 플랜지의 밀착성을 향상시킬 수 있는 확장형 플랜지를 갖는 자동차용 휠에 관한 것이다.The present invention relates to a wheel for an automobile on which a tire is mounted, and more particularly, to an automobile wheel having an expandable flange that can improve the adhesion between a tire and a wheel flange when pressure-resistant and load is applied to the tire.

자동차용 휠은 타이어가 장착되는 물품으로서 도 1에 도시된 바와 같이 타이어가 장착되는 림(100)과 차체에 체결하는 허브(101)로 구성되어 있는데, 여기서 상기 림(100)은 타이어(102)를 도 4와 같이 장착 유지시켜 주는 부분이며, 림폭(We)은 타이어(102)의 편평비와 밀접한 관계가 있다.A wheel for an automobile is an article on which a tire is mounted, and is composed of a rim 100 on which a tire is mounted and a hub 101 fastening to a vehicle body, as shown in FIG. 1, wherein the rim 100 is a tire 102. 4 is a part for maintaining the mounting as shown in FIG. 4, and the rim width W e is closely related to the flat ratio of the tire 102.

즉 림폭(We)이 작은 경우 사이드 휠 부분이 지나치게 노출되어 위험이 따르며, 반대로 림폭(We)이 지나치게 큰 경우에는 연비가 증가되면서 차체와의 간섭 등의 윈인이 된다.In other words, if the rim width (W e ) is small, the side wheel portion is excessively exposed, and if the rim width (W e ) is too large, fuel efficiency is increased, which is a cause of interference with the vehicle body.

통상적으로 일반 타이어를 저편평비 타이어처럼 보이도록 하는 동시에 휠의 크기보다 수인치 커보이도록 외관을 변경시킨 자동차용 휠에서 사용되고 있는 종래 확장형 플랜지는 타이어의 성능과 무관하게 외형적인 미감을 고려하여 발전하여 왔다.Conventional expansion flanges used in automobile wheels, which have been changed in appearance to make a general tire look like a low flat tire and at the same time appear to be several inches larger than the size of the wheel, have been developed in consideration of the external aesthetics regardless of the performance of the tire. .

예를 들어 도 7에 도시된 바와 같이 종래 확장형 플랜지를 갖는 자동차용 휠에서 휠의 기본치수에 해당하는 림 직경(D), 플랜지(103)의 높이(G), 플랜지의 반경(R1,R2), 비드 안착반경(R3) 및, 확장되지 않은 플랜지(103)의 형상은 통상적으로 TRA(The Tire and Rim Association), 또는 ETRTO(The European Tire and Rim Technical Organization)의 기준에 따라 왔다.For example, as shown in FIG. 7, in a conventional automobile wheel having an extended flange, the rim diameter D corresponding to the basic dimension of the wheel, the height G of the flange 103, and the radius of the flange R 1 and R 2 ), the bead seating radius R 3 and the shape of the unexpanded flange 103 have typically been in accordance with the standards of The Tire and Rim Association (TRA), or The European Tire and Rim Technical Organization (ETRTO).

한편, 종래 미국특허 제6,820,669호의 확장형 플랜지를 갖는 자동차용 휠에 서 타이어의 성능을 고려하기 위해 확장형 플랜지에 맞도록 타이어의 비드부를 변경한 기술을 제시하고 있지만, 일반 타이어를 사용하고도 저편평비 타이어처럼 보이게 할려는 당초 확장형 휠 플랜지의 목적과는 달리 타이어 제조를 변화시킴에 따라 실효성과 경제성에서 유리한 점이 없을 뿐만 아니라, 일반 자동차용 휠에서 오히려 사용이 제한되는 타이어에 불과한 단점을 지니고 있었다.On the other hand, the conventional US Patent No. 6,820,669 in the automobile wheel having an extended flange, in order to consider the performance of the tire to change the bead portion of the tire to fit the expandable flange, but a low flat ratio tire even using a regular tire Contrary to the purpose of the original expandable wheel flanges to make them look like they did not have advantages in terms of effectiveness and economics as they changed tire manufacturing, but also had disadvantages such as limited use of tires in general automobile wheels.

이와 같이 적절하지 않은 휠에서 확장형 플랜지의 형상은 타이어의 사이드월부와 플랜지 간의 밀착성을 떨어뜨리고 타이어 회전시 진동을 야기하여 승차감을 저하시키며, 타이어 손상을 초래하게 되는 문제점 등이 있었다.As such, the shape of the expandable flange in the wheel is inadequate to reduce the adhesion between the sidewall portion and the flange of the tire, causing vibration when the tire rotates, thereby lowering the riding comfort, there is a problem that causes tire damage.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 타이어의 내압충전 및 하중 작용시 이 타이어와 휠의 확장형 플랜지의 밀착성을 향상시키는 확장형 플랜지를 갖는 자동차용 휠을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above-described problems, and an object of the present invention is to provide a wheel for an automobile having an expandable flange which improves the adhesion between the expandable flange of the tire and the wheel when the tire is pressure-resistant and loaded. have.
