본 발명은 스핀들을 내륜으로 하는 차량용 휠 베어링 장치에 관한 것으로서, 더욱 상세하게는 부품 수를 줄이면서 규격화할 수 있도록 스핀들과 휠 장착 플랜지 사이에 휠 베어링을 결합함에 있어서 상기 휠 베어링의 작동을 위한 바깥쪽 내륜의 기능을 스핀들이 갖도록 한 것이다.The present invention relates to a wheel bearing device for a vehicle having a spindle as an inner ring, and more particularly, to an outer side for operating the wheel bearing in coupling the wheel bearing between the spindle and the wheel mounting flange so that the number of parts can be standardized. The spindle has the function of the inner ring.

종래의 차량용 휠 베어링 장치를 도 2와 관련하여 살펴보면 다음과 같다.Looking at the conventional wheel bearing device for a vehicle in relation to Figure 2 as follows.

즉, 너클(200)에 삽입된 스핀들(100)과 드럼(400) 및 휠(500)이 볼트 체결되는 휠 장착 플랜지(300) 사이에 구름운동을 위한 볼(700)(800)을 장착함에 있어서, 상기 스핀들(100)에 볼(700)(800)을 지지하는 안쪽 내륜(600)과 바깥쪽 내륜(600a) 2개를 결합한 다음 너트(900)로 고정한 것이다.That is, in mounting the balls 700 and 800 for rolling motion between the spindle 100 inserted into the knuckle 200 and the wheel mounting flange 300 to which the drum 400 and the wheel 500 are bolted together. In addition, the inner ring (600) and the outer ring (600a) for supporting the ball 700, 800 to the spindle 100 is combined and then fixed with a nut (900).

상기와 같은 구조의 차량용 휠 베어링 장치는 스핀들(100)과 휠 장착 플랜지(300) 사이에 구름운동을 위한 볼(700)(800)을 지지하기 위하여 정밀도를 요구하는 2개의 내륜(600)(600a)을 사용하기 때문에 부품의 가공과 조립성이 떨어지는 단점이 있다.The wheel bearing device for a vehicle having the above structure has two inner rings 600 and 600a that require precision in order to support the balls 700 and 800 for rolling motion between the spindle 100 and the wheel mounting flange 300. ) Has the disadvantage of inferior machining and assembly.

본 발명은 상술한 제반 문제점을 해결하기 위한 것으로서 스핀들과 휠 장착 플랜지 사이에 구름운동을 위한 볼을 결합하되 바깥쪽 볼은 스핀들 자체로 지지되게 상기 스핀들에 내륜의 기능을 부여함으로써 부품 수를 줄이고, 조립성을 향상시키는 것을 목적으로 한다. The present invention is to solve the above-mentioned problems by combining the ball for rolling motion between the spindle and the wheel mounting flange, the outer ball is reduced by the number of parts by giving the spindle the function of the inner ring to be supported by the spindle itself, It aims at improving assembly property.

본 발명의 스핀들을 내륜으로 하는 차량용 휠 베어링 장치의 구성을 이하, 첨부된 도면과 관련하여 상세하게 설명하면 다음과 같다.Hereinafter, a configuration of a wheel bearing device for a vehicle having a spindle of the present invention as an inner ring will be described in detail with reference to the accompanying drawings.

본 발명은 도 1에 도시된 바와 같이 스핀들(1)을 구성함에 있어서, 걸림턱(12)으로부터 연장된 선상에 바깥쪽 볼(8)을 지지하는 내륜의 기능을 갖도록 곡면 가공하여 마모를 방지하기 위한 표면 열처리를 함으로써 볼 지지부(9)를 구성하였다.In the present invention, in the configuration of the spindle 1 as shown in Figure 1, to prevent wear by processing the surface to have the function of the inner ring for supporting the outer ball 8 on the line extending from the locking step 12 The ball support part 9 was comprised by surface heat processing for it.

또한 상기 스핀들(1)에는 볼 지지부(9)에서 연장된 단차부(10)가 구성되며, 상기 단차부(10)는 안쪽 볼(7)을 지지하는 내륜(6)의 삽입 위치를 세팅하기 위한 것이다.In addition, the spindle 1 is provided with a stepped portion 10 extending from the ball support portion 9, the stepped portion 10 is for setting the insertion position of the inner ring 6 for supporting the inner ball (7) will be.

도면 중 미설명 부호 (13)은 오염방지용 베어링 시일(seal), (14)는 드럼(4)과 휠 장착 플랜지(3) 고정용 볼트, (15)는 휠(5) 장착용 볼트이다.In the drawings, reference numeral 13 denotes an anti-pollution bearing seal, 14 a bolt for fixing the drum 4 and the wheel mounting flange 3, and 15 a bolt for mounting the wheel 5.

이상과 같이 구성된 본 발명의 스핀들(1)과 드럼(4) 및 휠(5)이 볼트 체결되는 휠 장착 플랜지(3) 사이에 구름운동을 위한 볼(7)(8)을 장착함에 있어서는, 먼저 상기 스핀들(1)을 휠 장착 플랜지(3)의 일측에서 삽입하면서 바깥쪽 볼(8)을 끼워 상기 휠 장착 플랜지(3)와 스핀들(1)의 볼 지지부(9) 사이에 지지되도록 한 다음 안쪽 볼(7)을 휠 장착 플랜지(3)에 끼우면서 내륜(6)을 스핀들(1)에 삽입하되 단차부(10)까지 밀어 넣어 지지되도록 결합한다.In mounting the balls 7 and 8 for rolling motion between the spindle 1 of the present invention configured as described above, the wheel 4 and the wheel mounting flange 3 to which the drum 4 and the wheel 5 are bolted, first, Insert the spindle (1) from one side of the wheel mounting flange (3) while inserting the outer ball (8) so as to be supported between the wheel mounting flange (3) and the ball support (9) of the spindle (1) and then inside While inserting the ball (7) to the wheel mounting flange (3) is inserted into the inner ring (6) to the spindle (1), and coupled to be supported by pushing up to the step (10).

상기한 바와 같이 휠 장착 플랜지(3)의 중심부에 삽입되고, 구름운동을 하는 볼(7)(8)이 결합된 스핀들(1)은 너클(2)에 끼워 너트(11)로 고정된다.As described above, the spindle 1, which is inserted into the center of the wheel mounting flange 3, and the balls 7 and 8 which make rolling motions, is fitted to the knuckle 2 and fixed with a nut 11.

휠 장착 플랜지(3)와 스핀들(1) 사이에 결합된 안쪽 볼(7)은 내륜(6)에 지지되어 구름운동을 하고, 바깥 쪽 볼(8)은 상기 스핀들(1)에 일체 형성되어 내륜의 기능을 하는 볼 지지부(9)와 맞닿아 구름운동을 한다.The inner ball 7 coupled between the wheel mounting flange 3 and the spindle 1 is supported by the inner ring 6 for rolling motion, and the outer ball 8 is integrally formed with the spindle 1 and is inner ring Contact with the ball support (9) to function as a cloud movement.

이때 상기 스핀들(1)에 형성된 볼 지지부(9)는 표면 열처리가 되어 있어 볼(8)의 구름운동에 의한 마찰로 발생되는 마모를 방지하는 작용을 한다. At this time, the ball support portion 9 formed on the spindle 1 is surface heat treatment to prevent the wear caused by the friction caused by the rolling motion of the ball (8).

위와 같은 본 발명의 차량용 휠 베어링 장치는 스핀들 자체에 바깥쪽 볼을 지지하는 내륜 기능을 갖는 볼 지지부를 일체 형성함으로써 부품 수를 줄이고, 조립성을 향상시키는 등의 다대한 효과가 있다.The wheel bearing device for a vehicle of the present invention as described above has a great effect such as reducing the number of parts and improving the assemblability by integrally forming a ball support having an inner ring function to support the outer ball on the spindle itself.
