본 발명은 자동차의 톤휠에 관한 것으로, 특히 플라스틱 소재로 된 원형의 휠 본체와 지그재그 형상으로 도체 재질의 톤휠로 이루어진 자동차의 톤휠구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone wheel of an automobile, and more particularly, to a tone wheel structure of an automobile comprising a circular wheel body made of plastic material and a tone wheel made of conductor material in a zigzag shape.

종래 자동차의 차축에 설치되는 톤휠은 ABS 브레이크 유니트에 의한 차륜의 회전을 감지하는 데에 사용되고 있다.Conventionally, the tone wheel installed in the axle of the vehicle is used to detect the rotation of the wheel by the ABS brake unit.

도 1은 상기와 같은 종래의 톤휠이 차축에 장착된 상태가 도시되어 있는 바, 즉, 차축(1)의 외주면에 톤휠(2)이 일체로 회전되게 끼워져 장착되고, 상기 톤휠 (2)과 소정 간격을 두고 ABS 센서(3)가 너클에 고정되게 체결되며, 상기 ABS 센서(3)의 감지신호는 와이어를 통해 ABS 유니트에 인가되게 되어 있다.1 shows a state in which the conventional tone wheel as described above is mounted on the axle, i.e., the tone wheel 2 is integrally rotatably mounted on the outer circumferential surface of the axle 1, and the tone wheel 2 and the predetermined wheel are predetermined. At intervals, the ABS sensor 3 is fastened to the knuckle and the detection signal of the ABS sensor 3 is applied to the ABS unit via a wire.

상기 톤휠(2)의 후방에는 차축 하우징(4)이 차축에 끼워져 장착되어 있고, 상기 차축 하우징(4)에는 부츠(5)가 끼워져서 밴드(5)를 매개로 고정되게 장착되어 있다.An axle housing 4 is fitted to the axle at the rear of the tone wheel 2, and a boot 5 is fitted to the axle housing 4 so as to be fixed to the band 5.

상기와 같은 종래의 톤휠은 도체로 제작되는 데, 통상적으로 소결합금을 이용해서 제작되고 있고, 상기 톤휠의 외주면에는 다수개의 톱니가 일정 간격을 두고 원주방향으로 형성되어 있다.The conventional tone wheel as described above is made of a conductor, and is usually manufactured using a small alloy, and a plurality of teeth are formed in the circumferential direction at regular intervals on the outer circumferential surface of the tone wheel.

그런데, 최근에는 3세대 베어링이 차축에 사용됨에 따라 상기 톤휠의 형상도 커지게 되고, 이로 인해 자동차의 중량과 원가 상승을 야기시킨다고 하는 결점이 있었다.However, in recent years, as the third-generation bearing is used in the axle, the shape of the tone wheel is also increased, which causes a weight and cost increase of the vehicle.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 차축에 끼워져 장착되는 휠 본체를 플라스틱 소재로 제작하여 중량이 가볍고 저렴하게 구성할 수 있도록 한 자동차의 톤휠구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tone wheel structure of an automobile in which a wheel body fitted to an axle is made of a plastic material so that the weight is light and cheap.

상기와 같은 목적을 달성하기 위한 본 발명은, 플라스틱 소재로 만들어져 차축에 끼워져 일체로 장착되는 휠 본체와, 이 휠 본체의 외주면에 고정되게 결합되면서 지그재그 형상이 연속되게 이어진 톤휠을 갖춘 구조로 되어 있다.The present invention for achieving the above object is a structure having a wheel body made of a plastic material and fitted to the axle and integrally mounted, and a tone wheel fixedly coupled to the outer circumferential surface of the wheel body and zigzag continuously. .

바람직하기로는, 상기 휠 본체의 외주면에는 4개의 걸림돌기가 90도의 각도 를 두고 배치되면서 휠 본체의 양측면에 서로 엇갈리게 형성되어 상기 톤휠의 지그재그 형상이 상기 걸림돌기에 걸려져 지지되도록 되어 있다.Preferably, the outer peripheral surface of the wheel body is arranged with four locking projections at an angle of 90 degrees to be alternately formed on both sides of the wheel body so that the zigzag shape of the tone wheel is caught and supported by the locking projections.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 본 발명에 따른 톤휠이 사시도로 도시되어 있고, 도 3에는 본 발명에 따른 톤휠의 분리 사시도가 도시되어 있는 바, 즉 중량이 가볍고 상대적으로 가격이 저렴한 플라스틱 소재로 만들어지는 휠 본체(11)는 원형을 이루면서 그 중앙부위에는 차축에 끼워져 조립될 수 있도록 조립구멍(11a)이 형성되어 있는 데, 이 조립구멍도 원형으로 형성되어 있다.2 is a perspective view of the tone wheel according to the present invention, Figure 3 is an exploded perspective view of the tone wheel according to the present invention, that is, the wheel body (11) made of a light weight and relatively inexpensive plastic material (11) ) Is formed in a circular shape, and an assembling hole 11a is formed in the center portion thereof so as to be fitted to the axle, and this assembling hole is also formed in a circular shape.

그리고, 상기 휠 본체(11)의 외주면에 끼워져 결합되는 톤휠(12)은 지그재그 형상이 연속되게 이어진 원형을 이루고 있다.In addition, the tone wheel 12 fitted to and coupled to the outer circumferential surface of the wheel body 11 forms a circle in which zigzag shapes are continuously connected.

상기 톤휠(12)이 휠 본체(11)의 외주면에 결합되어져 일체로 회전될 수 있도록 하기 위해 상기 톤휠(12)을 휠 본체(11)에 고정시키는 방법으로서 휠 본체(11)의 외주면에는 대략 90도의 각도를 4개의 돌기(11b)가 일체로 돌출되게 형성된다.The tone wheel 12 is fixed to the wheel body 11 so that the tone wheel 12 is coupled to the outer circumferential surface of the wheel body 11 so as to be integrally rotated. Four projections 11b are formed so as to protrude integrally with the angle of the drawing.

상기 돌기(11b)는 휠 본체(11)의 양측면에 각각 서로 엇갈리는 방향으로 형성되어 상기 돌기(11b)에 상기 톤휠(12)의 지그재그 형상이 걸려져서 고정되게 되어, 상기 휠 본체와 톤휠이 회전될 때에 톤휠이 원심력을 받아도 상기 돌기에 의해 걸려져서 휠 본체로부터 이탈되지 않게 된다.The protrusions 11b are formed on both sides of the wheel body 11 in a mutually staggered direction so that the zigzag shape of the tone wheel 12 is fixed to the protrusions 11b so that the wheel body and the tone wheel are rotated. Even when the tone wheel is subjected to centrifugal force, the tone wheel is caught by the projections so that it is not separated from the wheel body.

상기 톤휠(12)은 자기장을 형성할 수 도체로 만들어져서 휠 본체의 회전을 ABS 센서가 감지할 수 있게 되어 있다.The tone wheel 12 is made of a conductor capable of forming a magnetic field, so that the ABS sensor can detect the rotation of the wheel body.

상기와 같이 플라스틱 소재의 휠 본체에 도체 성분의 톤휠이 조립되어 톤휠 을 구성함에 따라 톤휠의 전체 중량이 가볍게 될 뿐만 아니라 제작비용도 저렴하게 구성할 수 있게 되는 것이다.As described above, as the tone wheel of the conductive material is assembled to the wheel body of the plastic material, the total weight of the tone wheel is lighter as well as the manufacturing cost can be configured inexpensively.

이상 설명한 바와 같이 본 발명에 따른 의하면 자동차의 톤휠구조에 의하면, 플라스틱 소재로 제작되면서 차축에 끼워져 조립되는 휠 본체에 도체 성분의 지그재그 형상으로 연속되게 형성된 톤휠이 조립되어 톤휠을 구성함에 따라 중량이 가볍고 저렴하게 구성할 수 있는 등의 효과가 있게 된다.As described above, according to the present invention, the tone wheel structure of an automobile is made of a plastic material, and a ton wheel continuously formed in a zigzag shape of a conductor component is assembled to a wheel body fitted to an axle, and thus the weight is light. It can be configured at low cost.
