본 고안은 자동차 동력전달계통의 조인트 하우징과 보올 리테이너 결합구조에 관한 것으로, 특히 보올 리테이너에 고무막을 코팅형성하여 제작 및 가공공정을 단축하고 밀봉성을 증가시키며 원가절감에 기여하도록 된 조인트 하우징과 보올 리테이너 결합구조에 관한 것이다.The present invention relates to a joint housing and a bowl retainer coupling structure of an automobile power transmission system. In particular, a rubber membrane is coated on the bowl retainer to shorten the manufacturing and processing processes, increase sealing, and contribute to cost reduction. It relates to a retainer coupling structure.
일반적으로 자동차의 동력전달장치에 있어 트랜스미션으로부터의 동력은 차동기어로부터 조인트 하우징과 액슬 샤프트를 통해 전달되며, 상기 조인트 하우징에는 액슬 샤프트와 보올 리테이너가 연결된다.In general, in a power transmission device of a vehicle, power from a transmission is transmitted from a differential gear through a joint housing and an axle shaft, and an axle shaft and a bowl retainer are connected to the joint housing.
종래에는 제1도와 같이, 조인트 하우징(1)에 보올(2) 설치되어 있고, 보올(2)의 내면에 접촉되도록 액슬 샤프트(3)가 삽입설치되어 있으며, 조인트 하우징(1)의 일측 외주면에 삽입홈(4)이 형성되어 있다.Conventionally, as shown in FIG. 1, a bowl (2) is provided in the joint housing (1), and an axle shaft (3) is inserted in contact with the inner surface of the bowl (2), and on one outer peripheral surface of the joint housing (1). The insertion groove 4 is formed.
또한 상기 조인트 하우징(1)의 삽입홈(4)에는 o-링(5)이 결합되어 있고 조인트 하우징(1)의 일측 외주면을 통해 보올 리테이너(6)가 압입결합되면서 보올 리테이너(6)의 내부에 그리이스(7)가 충진되어 있다.In addition, the o-ring 5 is coupled to the insertion groove 4 of the joint housing 1, and the retainer 6 is press-fitted through one outer circumferential surface of the joint housing 1 to press the inside of the retainer 6. Grease 7 is filled.
이와같은 종래의 조인트 하우징(1)과 보올 리테이너(6)결합구조는, o-링(5)에 의해 조인트 하우징(1)과 보올 리테이너(6)의 결합부를 밀폐시킴으로써 보올 리테이너(6)의 내부에 충진된 그리이스(7)의 누출을 방지하고 있다.This conventional joint housing (1) and the retainer (6) coupling structure, the interior of the retainer (6) by sealing the coupling portion of the joint housing (1) and the retainer (6) by the o-ring (5) The grease (7) filled in the leak is prevented.
그러나 조인트 하우징(1)의 외주면에 삽입홈(4)을 가공형성하므로 작업공정이 증가하고 원가가 상승되는 단점이 있으며, 조인트 하우징(1)과 보올 리테이너(6)의 접촉면적이 적음과 동시에 o-링(5)의 변형 등으로 인하여 조인트 하우징(1)과 보올 리테이너(6)의 결합부 밀봉을 해치는 것은 물론, 보올 리테이너(6)에 충진된 그리이스(7)가 외부로 점차 누출되는 문제점이 있었다.However, since the insert groove 4 is formed on the outer circumferential surface of the joint housing 1, the work process increases and the cost increases. The contact area between the joint housing 1 and the retainer 6 is small and o Due to the deformation of the ring 5, the joint housing 1 and the retainer 6 are not sealed, and the grease 7 filled in the retainer 6 gradually leaks to the outside. there was.
이러한 현상은 곧 그리이스(7)에 의한 윤활성을 급격히 감소시켜 액슬 샤프트(3)와 보올(2)의 접촉마찰을 증가시키고, 심한 경우 액슬 샤프트(3)와 보올(2)의 마찰에 의한 소착을 초래함과 동시에 접촉면의 손상, 파손을 일으키는 치명적인 문제점이 있었다.This phenomenon rapidly reduces the lubricity by the grease (7) to increase the contact friction between the axle shaft (3) and the bowl (2), and in severe cases, the friction between the axle shaft (3) and the bowl (2) due to friction At the same time, there was a fatal problem causing damage and breakage of the contact surface.
본 고안의 목적은, 조인트 하우징과 보올 리테이너 결합부의 밀봉성을 증가시켜 그리이스의 누출을 방지함과 동시에 액슬 샤프트와 보올의 윤활성을 항시 원활하게 유지하는 자동차 동력전달계통의 조인트 하우징과 보올 리테이너 결합구조를 제공하기 위한 것이다.The object of the present invention is to increase the sealability of the joint housing and the retainer coupling portion to prevent grease leakage and to maintain the lubrication of the axle shaft and the bowl at all times smoothly to maintain the joint housing and the retainer coupling structure of the automotive power transmission system It is to provide.
본 고안의 다른 목적은, 가공 작업공정을 단축시키고 원가절감에 기여하는 조인트 하우징과 보올 리테이너 결합구조를 제공하기 위한 것이다.Another object of the present invention is to provide a joint housing and retainer coupling structure that shortens the machining work process and contributes to cost reduction.
본 고안은 상기의 목적을 달성하기 위하여, 보올 리테이너의 내주면에 고무막을 피복형성하여 조인트 하우징에 압입하는 것이 특징이다.The present invention is characterized in that the rubber film is formed on the inner circumferential surface of the retainer to press-fit the joint housing in order to achieve the above object.
이하, 본 고안의 구체적인 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
제2도는 본 고안 보올 조인트 리테이너의 분리상태 단면도이다.Figure 2 is a cross-sectional view of the separated joint retainer of the present invention.
도면과 같이, 조인트 하우징(1)에 보올(2)을 설치하고, 보올(2)의 내면에 접촉되도록 액슬 샤프트(3)를 삽입설치하며, 보올 리테이너(6)의 일측 내주면에 고무막(8)을 피복형성하여 상기 조인트 하우징(1)의 일단 외주면에 압입결합되도록 구성된 것이다.As shown in the figure, the bowl 2 is installed in the joint housing 1, the axle shaft 3 is inserted and installed in contact with the inner surface of the bowl 2, and the rubber membrane 8 is formed on one inner circumferential surface of the bowl retainer 6; ) Is formed so as to press-fit the outer peripheral surface of one end of the joint housing (1).
또한 상기의 보올 리테이너(6)의 내부에는 그리이스(7)을 충진하여 구성된 것이다.In addition, the inside of the bowl retainer 6 is filled with a grease (7).
따라서 본 고안은 조인트 하우징(1)에 별도의 삽입홈을 형성하거나 o-링을 사용할 필요없이 보올 리테이너(6)의 내주면에 고무막(8)을 형성하여 조인트 하우징(1)에 압입결합함으로써 가공공정이 간단하고, 특히 조인트 하우징(1)과 보올 리테이너(6)의 결합부의 밀봉면적이 고무막(8)에 의해 대폭 증가되어 보올 리테이너(6) 내부의 그리이스(7)가 외부로 누출되는 것을 방지한다.Therefore, the present invention forms a rubber film 8 on the inner circumferential surface of the bowl retainer 6 without the need for forming a separate insertion groove in the joint housing 1 or using an o-ring. The process is simple, and in particular, the sealing area of the joint portion of the joint housing 1 and the bowl retainer 6 is greatly increased by the rubber film 8, so that the grease 7 inside the bowl retainer 6 leaks to the outside. prevent.
여기서 조인트 하우징(1)과 보올 리테이너(6)는 고무막(8)에 면접촉(종래에는 o-링에 의해 선접촉되어 있음)되어 있으므로, 그 결합부의 접촉면적이 크게 증가시키며, 또한 보올 리테이너(6)의 그리이스(7) 누출이 방지됨으로써 윤활성능을 항시 최상으로 유지하여 액슬 샤프트(3)와 보올(2)의 접촉마찰을 제거한다.Here, since the joint housing 1 and the bowl retainer 6 are in surface contact with the rubber membrane 8 (previously in line contact by an o-ring), the contact area of the joint portion is greatly increased, and the bowl retainer is also increased. The grease (7) of (6) is prevented from leaking, so that the lubrication performance is always maintained at the best, thereby eliminating contact friction between the axle shaft (3) and the bowl (2).
이상과 같이 본 고안은, 보올 리테이너의 내주면에 고무막을 피복형성하여 조인트 하우징에 압입함으로써, 밀봉성의 증가와 함께 그리이스의 누출을 방지하여 윤활성을 항시 최상의 상태로 유지할 수 있고, 마찰에 의한 소착 및 액슬 샤프트와 조인트 하우징의 접촉면의 손상,파손을 방지하는 이점이 있다.As described above, the present invention forms a rubber film on the inner circumferential surface of the ball retainer and presses it into the joint housing, thereby preventing grease leakage along with an increase in sealing property, thereby maintaining the best lubricity at all times. There is an advantage of preventing damage and damage to the contact surface of the shaft and the joint housing.
