또한, 베어링(220)이 삽입된 허브베어링(200)의 돌출바(210) 끝단에는 외경의 길이가 확장되는 플랜지(211)가 형성되도록 하여 상기 허브베어링(200)이 너클(100)로부터 이탈되는 것을 방지하도록 하는 것이 바람직하다.In addition, at the end of the protruding bar 210 of the hub bearing 200 into which the bearing 220 is inserted, a flange 211 is formed to extend the length of the outer diameter so that the hub bearing 200 is separated from the knuckle 100. It is desirable to prevent it.

여기서, 허브베어링(200)의 원판 중앙에는 삽입홀(H)이 형성되어 상기 돌출바(210)와 연결되도록 하여 차륜과 드라이브 샤프트를 연결시킬 수 있게 한다.Here, the insertion hole (H) is formed in the center of the disc of the hub bearing 200 to be connected to the protruding bar 210 to connect the wheel and the drive shaft.

한편, 베어링(220)을 포함하는 허브베어링(200)과 너클(100)은 탄소섬유 강화 플라스틱으로 성형되도록 한다.Meanwhile, the hub bearing 200 and the knuckle 100 including the bearing 220 may be formed of carbon fiber reinforced plastic.

이때, 상술한 바와 같이 허브베어링(200)과 너클(100)은 탄소섬유 강화 플라스틱으로 성형되되, 베어링(220)의 내주면과 돌출바(210)의 외주면은 스틸 재질로 성형되어 볼(B)에 의한 베어링(220) 작동이 용이하도록 한다.
At this time, as described above, the hub bearing 200 and the knuckle 100 are molded of carbon fiber reinforced plastic, and the inner circumferential surface of the bearing 220 and the outer circumferential surface of the protruding bar 210 are formed of steel and formed on the ball B. To facilitate the operation of the bearing 220.

이하, 본 발명의 작용 및 효과를 설명하면 다음과 같다.Hereinafter, functions and effects of the present invention will be described.

도 2 및 도 3에 도시된 바와 같이, 너클(100)의 관통홀(110)에 베어링(220)을 포함하는 일체형의 허브베어링(200)이 삽입되어, 상기 허브베어링(200) 일측에 휠이 장착되고 타측에는 드라이브 샤프트가 삽입되도록 함으로써 주행 시 발생되는 진동을 차체와 연동된 쇼크 업소버로 전달할 수 있게 한다.As shown in FIGS. 2 and 3, an integral hub bearing 200 including a bearing 220 is inserted into the through-hole 110 of the knuckle 100, so that a wheel is formed at one side of the hub bearing 200. By mounting the drive shaft on the other side, the vibration generated during driving can be transmitted to the shock absorber linked to the vehicle body.

이때, 주행 시 드라이브 샤프트가 안정적으로 회전하게 되는 것은 허브베어링(200)의 돌출바(210)와 베어링(220) 사이에 다수의 볼(B)이 구비되어 상기 허브베어링(200) 작동이 원활하게 진행되기 때문이다.At this time, the drive shaft is to be stably rotated during driving is provided with a plurality of balls (B) between the protruding bar 210 and the bearing 220 of the hub bearing 200 smoothly operation of the hub bearing 200 Because it is going.

한편, 본 발명에서 베어링(220)을 포함하는 허브베어링(200)과 너클(100)은 탄소섬유 강화 플라스틱으로 성형되도록 하여 부품을 경량화 시키는 동시에 복합소재 적용을 통한 강도와 내구 성능을 향상시킬 수 있게 하여 상품성과 안전성을 향상시킬 수 있게 한다.Meanwhile, in the present invention, the hub bearing 200 and the knuckle 100 including the bearing 220 may be molded from carbon fiber reinforced plastic to reduce the weight of the parts and to improve strength and durability through the application of composite materials.
