Description

자동차의 자재이음용 등속조인트의 결합구조Combination structure of constant velocity joint for material joint of automobile

본 고안은 자동차의 자재이음용 등속조인트의 결합구조에 관한 것으로, 특히 추진축의 결합부형상과 인너레이스의 결합홀형상을 단순화시킴으로써 작업자의 작업성을 향상시킴은 물론, 동력전달시 등속조인트의 강석을 향상시킬 수 있도록 된 자동차의 자재이음용 등속조인트의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a constant velocity joint for automobile joints. In particular, the workability of the operator is improved by simplifying the coupling part shape of the propulsion shaft and the coupling hole shape of the inner race, as well as the rigidity of the constant velocity joint during power transmission. The present invention relates to a joint structure of a constant velocity joint for a material joint of a vehicle that can be improved.

일반적으로 기관의 동력은 변속기를 거쳐 추진축에 의해 뒤차축으로 전달되며, 변속기는 기관 및 클러치와 함께 프레임에 설치되어 있고, 뒤차축은 섀시스프링을 사이에 두고 차체에 설치되어 있으므로 노면에서 오는 충격이나 적재하중의 변화에 따라 상하, 전후로 움직인다. 따라서 기관의 동력을 원활하게 뒷차축에 전달하기 위해 추진축의 양쪽 끝에 자재이음과 추진축의 앞쪽 또는 중간부분에 슬리이브요크를 설치한다.In general, the engine power is transmitted to the rear axle by the propulsion shaft through the transmission, and the transmission is installed on the frame together with the engine and clutch, and the rear axle is installed on the body with the chassis spring in between, so It moves up and down and back and forth according to the change of load. Therefore, in order to smoothly transfer engine power to the rear axle, a sleeve yoke is installed at both ends of the prop shaft and at the front or middle of the prop shaft.

여기서, 상기 자재이음은 두축이 일직선상에 있지 않고, 어떤 각도를 가진 두개의 축사이에 동력을 전달할 때 사용되는 조인트로써, 구조에 따라 프렉시블저인트, 카르단조이트, 트렉터조인트, 등속조인트로 분류되는 바, 상기 등속조인트(Constant Velocity Joint)는 앞바퀴 구동차나 전륜 구동차에서 종감속장치에 연결된 구동차축에 설치되어 바퀴의 동력전달용으로 사용되며, 동력 전달시 조인트의 각속도변동을 없애도록(등속하도록) 개량한 조인트를 일컫는다.Here, the material joint is a joint used when transmitting power between two axes having a certain angle without two axes in a straight line, and classified into flexible joint, cardan joint, tractor joint, and constant velocity joint according to the structure. The constant velocity joint (Constant Velocity Joint) is installed on the drive axle connected to the longitudinal deceleration device in the front wheel drive car or front wheel drive car is used for power transmission of the wheel, so as to eliminate the angular velocity variation of the joint during power transmission ( ) Refers to the improved joint.

이러한 등속조인트의 일반적인 구조는 도 1에 도시된 바와 같이, 인너레이스(2)의 결합홀(2a)에 추진축(1)의 결합부(1a)가 삽입 관통되어 2개의 원형클립(3)을 매개로 고정되고, 상기 인너레이스(2)의 상단부에는 등속조인트외륜(4)이 배설되어 있다.The general structure of such a constant velocity joint, as shown in Figure 1, the coupling portion (1a) of the propulsion shaft (1) is inserted through the coupling hole (2a) of the inner race 2 through the two circular clips (3). Is fixed to the upper end of the inner race 2, and a constant velocity joint outer ring 4 is disposed.

그리고, 상기 원형클립(3)은 인너레이스(2)의 결합홀(2a)에 관통 삽입된 추진축(1)이 이탈되는 것을 방지하기 위해 사용되는 것으로써, 상기 인너레이스(2)의 좌우측부와 밀착된 위치에 각각 고정되도록 되어 있다.In addition, the circular clip 3 is used to prevent the propulsion shaft 1 inserted through the coupling hole 2a of the inner race 2 from being separated, and the left and right sides of the inner race 2 It is fixed to each in close contact.

여기서, 상기 추진축(1)의 종래 형상은 도2에 도시된 바와 같이, 지름의 크기가 일정한 원형상으로 형성됨과 더불어 일측 끝단의 결합부(1a)에는 외주면 전체에 걸쳐 스플라인(1b)이 형성되어 있고, 상기 인너레이스(2)의 종래 형상은 도 3에 도시된 바와 같이, 중앙부위에는 상기 추진축의 형상과 동일한 모양인 결합홀(2a)이 형성됨과 더불어 이 결합홀(2a)에는 외주면을 따라 상기 추진축(1)의 스플라인(1b)과 결합되도록 된 스플라인(2b)이 형성되어 있다.Here, the conventional shape of the propulsion shaft 1, as shown in Figure 2, the size of the diameter is formed in a circular shape, and the spline (1b) is formed on the entire outer peripheral surface in the coupling portion (1a) of one end In the conventional shape of the inner race 2, as shown in FIG. 3, a coupling hole 2a having the same shape as that of the propulsion shaft is formed at the center portion, and the coupling hole 2a is formed along the outer circumferential surface thereof. A spline 2b is formed to engage with the spline 1b of the propulsion shaft 1.

따라서 추진축(1)의 결합부(1a)끝단을 인너레이스(2)의 결합홀(2a)에 밀착시킨 후, 이 결합홀(2a)을 관통하도록 추진축(1)을 삽입시키게 되면 도 4에 도시된 바와 같이, 추진축(1)의 스플라인(1a)과 결합홀(2a)의 스플라인(2b)이 서로 맞물려진 상태에서 슬라이딩 이동됨으로써 추진축(1)과 인너레이스(2)가 결합되어 진다.Therefore, if the end of the engaging portion (1a) of the propulsion shaft (1) is in close contact with the engaging hole (2a) of the inner race 2, and then the propulsion shaft (1) is inserted through the engaging hole (2a) shown in Figure 4 As described above, the propulsion shaft 1 and the inner race 2 are engaged by slidingly moving in a state where the spline 1a of the propulsion shaft 1 and the spline 2b of the coupling hole 2a are engaged with each other.

그러나 이와 같은 종래의 구조에 의하면, 추진축(1)의 결합부(1a)형상과 인너레이트의 결합홀(2a)형상이 원형으로 형성됨으로 인해 서로 결합된 결합부(1a)와 결합(2a)의 구조가 복잡하여 작업자의 작업성능 및 정비성능이 저하되는 문제점이 있었다.However, according to such a conventional structure, since the shape of the coupling portion 1a of the propulsion shaft 1 and the shape of the coupling hole 2a of the inner rate are formed in a circular shape, the coupling portion 1a and the coupling 2a of each other are coupled. Due to the complicated structure, there was a problem in that the work performance and maintenance performance of the worker were deteriorated.

이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 추진축의 결합부형상과 인너레이스의 결합홀형상을 삼각모양으로 형성시켜 서로 결합된 결합부와 결합홀의 구조를 단순화시킴으로써 작업성능 및 정비성능이 향상되도록 된 자동차의 자재이음용 등속조인트의 결합구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and by forming a coupling hole shape of the propulsion shaft and the coupling hole shape of the inner race in a triangular shape to simplify the structure of the coupling portion and the coupling hole coupled to each other, work performance and maintenance It is an object of the present invention to provide a joint structure of a constant velocity joint for a material joint of a vehicle to improve performance.
