Description
본 발명은 자동차의 자재이음용 등속조인트의 결합구조에 관한 것으로, 특히 추진축의 형상이 변경됨과 더불어 이 추진축의 결합부와 인너레이스 결합홀과의 결합방법이 변경되어 부품수가 절감됨은 물론, 작업성이 향상되도록 된 자동차의 자재이음용 등속조인트의 결합구조에 관한 것이다.The present invention relates to a joint structure of a constant-velocity joint for use in an automobile, particularly, a shape of a propeller shaft is changed, and a method of joining a joint portion of the propeller shaft and an inner race joint hole is changed, The present invention relates to a joint structure of a constant-velocity joint for use in a vehicle.
일반적으로 기관의 동력은 변속기를 거쳐 추진축에 의해 뒷차축으로 전달되며, 변속기는 기관 및 클러치와 함께 프레임에 설치되어 있고, 뒷차축은 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.Generally, the power of the engine is transmitted through the transmission to the rear axle by the propulsion shaft. The transmission is installed on the frame together with the engine and the clutch, and the rear axle is installed on the vehicle body with the chassis spring interposed therebetween. It moves up and down, back and forth according to the change of load. Therefore, in order to smoothly transmit the power of the engine to the rear axle, a sleeve yoke is installed at the front or middle portion of the shafts and the shafts at both ends of the shafts.
여기서, 상기 자재이음은 두축이 일직선상에 있지 않고, 어떤 각도를 가진 두개의 축사이에 동력을 전달할 때 사용되는 조인트로써, 구조에 따라 프렉시블조인트, 카르단조인트, 트렉터조인트, 등속조인트로 분류되는 바, 상기 등속조인트(Constant Velocity Joint)는 앞바퀴 구동차나 전륜 구동차에서 종감속장치에 연결된 구동차축에 설치되어 바퀴의 동력전달용으로 사용되며, 동력전달시 조인트의 각 속도변동을 없애도록(등속하도록) 개량한 조인트를 일컫는다.Here, the material joint is a joint used when the two axes are not in a straight line, but is used to transmit power between two angles having different angles. The joint is classified into a flexible joint, a cardan joint, a tractor joint and a constant velocity joint The constant velocity joint is installed on the driving axle connected to the longitudinal decelerating device in the front wheel drive vehicle or the front wheel drive vehicle and is used for power transmission of the wheels so as to eliminate fluctuation of each speed of the joint during power transmission To improve joints.
이러한 등속조인트의 일반적인 구조는 제1도에 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 is such that the engaging portion 1a of the propeller shaft 1 is inserted into the engaging hole 2a of the inner race 2 to insert the two circular clips 3 And a constant velocity joint outer ring 4 is disposed at an upper end portion of the inner race 2.
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.The circular clip 3 is used to prevent the propelling shaft 1 inserted through the coupling hole 2a of the inner race 2 from being detached from the inner race 2, Respectively.
여기서, 상기 추진축(1)의 종래 형상은 제2도에 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 제3도에 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.As shown in FIG. 2, the conventional shape of the propeller shaft 1 is formed into a circular shape having a constant diameter, and a spline 1b is formed on the joint portion 1a at one end thereof over the entire outer circumferential surface As shown in FIG. 3, in the conventional shape of the inner race 2, a coupling hole 2a having the same shape as the shape of the propeller shaft is formed on the central portion, and an outer peripheral surface is formed in the coupling hole 2a A spline 2b engaged with the spline 1b of the propeller shaft 1 is formed.
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 제4도에 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 tip of the engaging portion 1a of the propeller shaft 1 is brought into close contact with the engaging hole 2a of the inner race 2 and then the engaging shaft 1 is inserted through the engaging hole 2a, As shown in the drawing, the spline 1a of the propeller shaft 1 and the spline 2b of the coupling hole 2a are slidingly engaged with each other, so that the propeller shaft 1 and the inner race 2 are engaged.
그러나 이와 같은 종래의 구조에 의하면, 인너레이스(2)와 결합된 추진축(1)의 결합부(1a)끝단 소정부위(K)가 상기 인너레이스(2)를 왼전히 관통하여 배치됨과 더불어 상기 추진축(1)을 고정시키기 위해서 2개의 원형클립(3)을 사용함으로 인해 결합부재들이 필요이상으로 과다하게 소모되어 원가가 상승될 뿐만 아니라 작업자의 작업공수가 증가되어 작업성능이 저하되는 문제점이 있었다.However, according to the conventional structure as described above, the predetermined portion K at the end of the engaging portion 1a of the propeller shaft 1 coupled with the inner race 2 is arranged so as to penetrate the inner race 2 completely left, The use of the two circular clips 3 for fixing the fastener 1 causes the joint members to be excessively consumed unnecessarily, resulting in an increase in the cost, as well as an increase in the number of workings of the worker, thereby deteriorating the work performance.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 추진축의 결합부길이를 인너레이스의 결합홀길이와 동일하게 형성시킴과 더불어 상기 결합부가 시작되는 추진축의 표면부에는 외부로 돌출되도록 된 걸림턱을 형성시키고, 코킹(Caulking)을 사용하여 추진축의 결합부와 인너레이스의 결합부가 결합되어져, 부품수가 절감됨으로 인해 원가가 절감될 뿐만 아니라 작업자의 작업공수가 감소되어 작업성능이 향상되도록 된 자동차의 자재이음용 등속조인트의 결합구조를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a propeller shaft, The engagement portion of the propeller shaft and the engagement portion of the inner race are combined using caulking to reduce the number of parts, thereby reducing the cost, The present invention provides a joint structure of a constant velocity joint for a vehicle.
