도 1과 도 2를 참조하면, 본 발명의 일 실시예에 따른 허브 베어링 조립장치(1)는 허브부(10)와, 구동축부(20)와, 볼트부(30)와, 탄성부(40)를 포함한다.1 and 2, the hub bearing assembly apparatus 1 according to an embodiment of the present invention includes a hub portion 10, a drive shaft portion 20, a bolt portion 30, and an elastic portion 40 ).

허브부(10)에는 구동축부(20)와의 체결을 위해 볼트부(30)가 관통되도록 체결홀부(15)가 형성된다. 허브부(10)의 외측에는 허브베어링(18)이 장착된다.In the hub portion 10, a fastening hole portion 15 is formed so that the bolt portion 30 penetrates for fastening with the drive shaft portion 20. A hub bearing 18 is mounted outside the hub portion 10.

구동축부(20)는 허브부(10)와 연결되어 엔진에서 생성된 구동력을 허브(10)에 전달한다.The driving shaft portion 20 is connected to the hub portion 10 and transmits the driving force generated by the engine to the hub 10.

볼트부(30)는 허브부(10)와 구동축부(20)를 결합하여, 허브부(10)가 구동축부(20)에서 분리되는 것을 차단한다.The bolt portion 30 combines the hub portion 10 and the drive shaft portion 20 to block the hub portion 10 from being separated from the drive shaft portion 20.

탄성부(40)는 볼트부(30)와 허브부(10) 사이에 배치되어 볼트부(30)의 충격을 흡수한다.The elastic part 40 is disposed between the bolt part 30 and the hub part 10 to absorb the impact of the bolt part 30.

일 예로, 탄성부(40)는 도 1과 도 2를 기준으로 좌측단부가 볼트부(30)를 지지하고, 우측단부가 허브부(10)를 지지한다. 탄성부(40)는 코일스프링 형상을 하여 체결홀부(15)를 관통하는 볼트부(30)를 감싼다.As an example, the elastic part 40 has a left end supporting the bolt part 30 based on FIGS. 1 and 2, and a right end supporting the hub part 10.

이로 인해, 허브부(10)와 구동축부(20)의 결합력이 증대되어 구동축부(20)의 회전력 전달이 원활하게 이루어진다.
Due to this, the coupling force between the hub portion 10 and the drive shaft portion 20 is increased, so that the rotational force transmission of the drive shaft portion 20 is smoothly performed.

도 3은 본 발명의 일 실시예에 따른 허브 베어링 조립장치에서 허브부와 탄성부의 접촉관계를 개략적으로 나타내는 도면이다.3 is a view schematically showing a contact relationship between a hub portion and an elastic portion in a hub bearing assembly apparatus according to an embodiment of the present invention.

도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 허브부(10)는 허브몸체(11)와, 허브턱(12)과, 허브돌기(13)를 포함한다.1 to 3, the hub portion 10 according to an embodiment of the present invention includes a hub body 11, a hub jaw 12, and a hub protrusion 13.

허브몸체(11)는 탄성부(40)와 접촉되고, 볼트부(30)가 관통되는 체결홀부(15)가 형성된다. 일 예로, 허브몸체(11)는 구동축부(20)에 형성되는 체결홈부(21)를 감싸도록 형성된다.The hub body 11 is in contact with the elastic portion 40, a fastening hole portion 15 through which the bolt portion 30 is formed is formed. For example, the hub body 11 is formed to surround the fastening groove 21 formed in the drive shaft portion 20.

허브턱(12)은 허브몸체(11)에서 연장되고 볼트부(30)가 걸림 고정된다. 볼트부(30)가 허브턱(12)에 걸려 볼트부(30)의 삽입이 제한된다.The hub jaw 12 extends from the hub body 11 and the bolt portion 30 is locked and fixed. The bolt portion 30 is caught by the hub jaw 12 and insertion of the bolt portion 30 is restricted.

허브돌기(13)는 허브몸체(11)에 형성되고, 탄성부(40)의 일방향 회전을 허용하고, 타방향 회전을 제한한다. The hub protrusion 13 is formed on the hub body 11, allows rotation of the elastic part 40 in one direction, and restricts rotation in the other direction.

일 예로, 허브돌기(13)는 탄성부(40)와 접촉되는 허브몸체(11)에 형성된다. 허브돌기(13)는 복수개가 원주방향으로 형성되고, 경사를 갖도록 돌출되어 탄성부(40)의 타방향 회전만을 제한한다.
For example, the hub protrusion 13 is formed on the hub body 11 in contact with the elastic portion 40. The plurality of hub protrusions 13 are formed in a circumferential direction, and protrude to have an inclination, thereby limiting only rotation of the elastic part 40 in the other direction.

도 4는 본 발명의 일 실시예에 따른 허브 베어링 조립장치에서 볼트부와 탄성부의 접촉관계를 개략적으로 나타내는 도면이다.4 is a view schematically showing a contact relationship between a bolt portion and an elastic portion in a hub bearing assembly apparatus according to an embodiment of the present invention.

도 1과 도 2 및 도 4를 참조하면, 본 발명의 일 실시예에 따른 볼트부(30)는 볼트몸체(31)와, 볼트머리(32)와, 볼트돌기(33)를 포함한다.1, 2 and 4, the bolt portion 30 according to an embodiment of the present invention includes a bolt body 31, a bolt head 32, and a bolt projection 33.

볼트몸체(31)는 외주면에 나사산이 형성되고, 허브부(10)의 체결홀부(15)를 관통한다. 볼트몸체(31)는 구동축부(20)의 체결홈부(21)에 나사 결합된다.The bolt body 31 is formed with a thread on the outer circumferential surface and penetrates the fastening hole portion 15 of the hub portion 10. The bolt body 31 is screwed to the fastening groove 21 of the drive shaft portion 20.

볼트머리(32)는 볼트몸체(31)의 단부에 형성되고 측방향으로 돌출되며, 볼트돌기(33)는 볼트머리(32)에 형성되어 탄성부(40)에 접촉된다. The bolt head 32 is formed at the end of the bolt body 31 and protrudes laterally, and the bolt projection 33 is formed on the bolt head 32 and contacts the elastic part 40.

볼트돌기(33)는 일방향 회전시 탄성부(40)와의 간섭이 발생하지 않고, 타방향 회전시 탄성부(40)에 걸려 타방향 회전이 제한된다.The bolt protrusion 33 does not interfere with the elastic part 40 when rotating in one direction, and is caught by the elastic part 40 when rotating in the other direction, thereby limiting rotation in the other direction.

일 예로, 볼트돌기(33)는 탄성부(40)와 접촉되는 볼트머리(32)의 측면에 형성된다. 볼트돌기(33)는 복수개가 원주방향으로 형성되고, 경사를 갖도록 돌출된다.For example, the bolt projection 33 is formed on the side of the bolt head 32 in contact with the elastic portion 40. A plurality of bolt projections 33 are formed in the circumferential direction, and protrude to have a slope.

따라서, 볼트부(30)가 체결홈부(21)에 결합되도록 시계방향으로 회전되면, 볼트돌기(33)는 탄성부(40)와 간섭되지 않는다.Therefore, when the bolt portion 30 is rotated clockwise so as to be coupled to the fastening groove portion 21, the bolt projection 33 does not interfere with the elastic portion 40.

그러나, 볼트부(30)가 시계 반대방향으로 회전되면 볼트돌기(33)가 탄성부(40)에 걸리므로, 볼트부(30)의 풀림을 방지할 수 있다.
However, when the bolt portion 30 is rotated counterclockwise, the bolt projection 33 is caught by the elastic portion 40, so that the bolt portion 30 can be prevented from loosening.

본 발명의 일 실시예에 따른 허브 베어링 조립장치의 작용과 효과를 설명하면 다음과 같다.When explaining the action and effect of the hub bearing assembly apparatus according to an embodiment of the present invention.

허브몸체(11)에 구동축부(20)가 삽입되어 체결홀부(15)와 체결홈부(21)가 일직선상에 배치되도록 하고, 허브몸체(11)의 단부와 구동축부(20)에 형성되는 치열(50)이 서로 맞물리도록 이들을 밀착시킨다.The drive shaft portion 20 is inserted into the hub body 11 so that the fastening hole portion 15 and the fastening groove portion 21 are arranged in a straight line, and the teeth formed at the end of the hub body 11 and the drive shaft portion 20 These are brought into close contact with each other so that 50 are engaged with each other.

상기한 상태에서, 탄성부(40)가 감긴 볼트몸체(31)가 체결홀부(15)를 관통하여 체결홈부(21)에 체결된다.In the above-described state, the bolt body 31 around which the elastic part 40 is wound passes through the fastening hole part 15 and is fastened to the fastening groove part 21.

이때, 볼트머리(32)가 허브턱(12)에 걸려 체결홈부(21)와의 결합방향으로 회전이 제한되므로, 볼트몸체(31)의 과도한 조임을 방지할 수 있다.At this time, since the bolt head 32 is caught in the hub jaw 12 and rotation is limited in the coupling direction with the fastening groove 21, excessive tightening of the bolt body 31 can be prevented.

볼트부(30)에 의해 허브부(10)와 구동축부(20)의 결합이 완료되면, 엔진에서 생성된 구동력이 구동축부(20)를 통해 허브부(10)에 전달되고, 치열(50)에 의해 구동축부(20)와 면접촉되는 허브부(10)는 회전되어 차량이 이동된다.When the coupling of the hub portion 10 and the drive shaft portion 20 is completed by the bolt portion 30, the driving force generated by the engine is transmitted to the hub portion 10 through the drive shaft portion 20, and the dentition 50 The hub portion 10 in surface contact with the drive shaft portion 20 is rotated to move the vehicle.
