Abstract

본 발명은 견인 조인트의 굴절시에 센터 요크는 크로스 베어링으로 설치된 양측 요크의 후방에 설치된 스프링의 탄력에 의하여 동력 전달 축과 스프라인으로 연결되어 있어 양측 요크는 스프라인을 타고 이동되므로 어느 각도에서도 항상 중심으로 센터 요크가 이동되어도 수평을 유지하고 있어 양측 요크의 단부가 항상 등각을 이루고 있어 부하가 균일하게 걸리어 굴절 조인트의 파손을 최소화시키며, 또한 전방 요크의 외부 동체 하부에는 견인봉을 연결하는 연결 봉을 핀으로 유착하고 있어 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해지지 않아 각 조인트의 파손을 최소화시키게 한 것이다.In the present invention, when the traction joint is deflected, the center yoke is connected to the power transmission shaft and the spline by the elasticity of the spring installed at the rear of both yokes installed as cross bearings, so that both yokes are moved along the spline so that they are always at any angle. Even when the center yoke is moved to the center, the level is maintained evenly so that the ends of both yokes are always equiangular, so the load is uniformly applied to minimize the breakage of the articulation joint, and the connecting rod is connected to the lower part of the outer body of the front yoke. The rods are bonded with pins, so the angle of refraction can be made larger, so that no excessive force is applied to each yoke to minimize the breakage of each joint.

본 발명은 트랙터 작업기용 견인 굴절 조인트에 관한 것이다, 좀더 자세하게는 견인 조인트의 굴절시에 센터 요크는 크로스 베어링으로 설치된 양측 요크의 후방에 설치된 스프링의 탄력에 의하여 동력 전달 축과 스프라인으로 연결되어 있어 양측 요크는 스프라인을 타고 이동되므로 어느 각도에서도 항상 중심으로 센터 요크가 이동되어도 수평을 유지하고 있기 때문에 양측 요크의 단부가 항상 등각을 이루고 있어 부하가 균일하게 걸리어 굴절 각을 크게 할 경우에도 굴절 조인트의 파손을 최소화시킬 수 있으며, 또한 전방 요크의 외 동체 하부에는 견인봉을 연결하는 연결 봉을 핀으로 유착하고 있기 때문에 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해 지지 않아 각 조인트의 파손을 최소화시키게 한 것이다.The present invention relates to a traction articulation joint for a tractor work machine. More specifically, the center yoke is connected to a power transmission shaft and a spline by the elasticity of a spring installed at the rear of both yokes provided as cross bearings when the traction joint is bent. Since both yokes are moved along the spline, they are always horizontal even when the center yoke is moved to the center at any angle. Therefore, the ends of both yokes are always equiangular. The damage of the joint can be minimized, and since the connecting rod connecting the tow bar is attached to the lower part of the outer body of the front yoke with a pin, the angle of refraction can be increased, and each joint is not applied to the yoke without excessive force. It is to minimize the breakage of.

종래에는 도 1에서와 같이 견인 굴절 조인트는 한쪽 요크(1)는 동력 전달축(2)에 용접하였기 때문에 각도를 조절하기 위하여 조인트를 굴절시키게 되면 양측 요크(1)(1a)의 굴절 각도가 서로 다르기 때문에 고정된 동력 전달 축(2)이 밀어 올리는 힘의 반작용에 의하여 크로스 베어링(3)이 견딜 수 없는 힘의 작용으로 파손되며, 메인축의 베어링에도 무리한 힘이 가해져서 파손이 쉽게 되는 동시에 견인 굴절 조인트와 연결된 유니버설 조인트가 견디지 못하고 파손되는 경우가 허다하여 작업의 지장을 줄뿐 아니라 보수 수리비가 많이 드는 문제점이 있었고, 상태에 따라서는 폐기시키는 예가 허다하였다.Conventionally, as shown in FIG. 1, the traction articulation joint has one yoke 1 welded to the power transmission shaft 2, so when the joint is bent to adjust the angle, the articulation angles of both yokes 1 and 1a are mutually different. Due to the difference, the cross bearing 3 is broken by the action of the force that the fixed power transmission shaft 2 pushes up, and the bearing of the main shaft is excessively applied to the bearing and the breakage is easy, and the traction deflection The universal joints connected to the joints were often unbearable and damaged, which not only interfered with the work but also costly to repair and repair.

본 발명은 종래의 문제점을 최소화하기 위하여 견인 굴절 조인트의 굴절시에 센터 요크는 크로스 베어링으로 설치된 양측 요크의 후방에 설치된 스프링의 탄력에 의하여 동력 전달 축에 형성된 스프라인을 타고 이동되므로 어느 각도에서도 항상 중심으로 센터가 이동되어도 수평을 유지하고 있어 양측 요크의 단부가 항상 등각을 이루고 있어 굴절 각을 크게 할 경우에도 굴절 조인트의 파손을 최소화시킬 수 있으며, 또한 전방 요크의 외부 동체 하부에는 견인봉을 연결하는 연결 봉을 핀으로 유착하고 있기 때문에 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해 지지 않아 각 조인트의 파손을 최소화시키게 한 것이다.In the present invention, in order to minimize the conventional problems, the center yoke is always moved at any angle since the center yoke is moved along the spline formed on the power transmission shaft by the elasticity of the spring installed at the rear of both yokes installed as cross bearings. Even when the center is moved to the center, the level is maintained evenly, so the ends of both yokes are always equiangular to minimize the breakage of the articulation joint even when the angle of refraction is increased, and the towbar is connected to the lower part of the outer body of the front yoke. Since the connecting rods are bonded to each other with pins, the angle of refraction can be increased, so that excessive force is not applied to each yoke to minimize breakage of each joint.

도 2는 본 발명의 정면도의 일부 단면도로서 견인 굴절 조인트의 양측 외 동체(10)(10a)내부 중간에 센터 요크(11)를 두고 양측 요크(12)(12a)를 크로스 베어링(13)으로 연결 설치하고, 양측 요크(12)(12a)의 후방에 스프라인을 형성한 삽입공(14)(14a)에 스프라인이 형성된 동력 전달 축(15)(15a)을 삽입 설치하여 이동될 수 있게 하고, 양측 동력 전달 축(15)(15a)과 요크(12)(12a) 사이에는 양측 캡(20)(20a) 내부에 스프링(21)을 설치한 것이다. 도 3은 본 발명의 평면에서 본 요부 단면도이고, 도 4는 본 발명의 평면에서 본 굴절 상태 요부 단면도로서 견인 굴절 조인트의 굴절시에 센터 요크(11)는 크로스 베어링(13)으로 설치된 양측 요크(12)(12a)의 후방에서 양측 캡(20)(20a) 내에 설치된 스프링(21)의 탄력에 의하여 동력 전달 축(15)(15a)과 양측 요크(12)(12a)는 스프라인으로 연결되어 있어 양측 요크(12)(12a)는 스프라인을 타고 이동되므로 어느 각도에서도 항상 센터 요크(11)가 중심으로 이동되어 수평을 유지하고 있기 때문에 양측 요크(12)(12a)의 단부가 항상 등각을 이루고 있어 부하가 균일하게 걸리어 굴절 각을 크게 할 경우에도 굴절 조인트의 파손을 최소화시킬 수 있으며, 또한 전방 요크(12)의 외 동체(10) 하부에는 견인봉(30)을 연결하는 연결 봉(31)을 핀(32)으로 유착하고 있기 때문에 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해 지지 않아 각 조인트의 파손을 최소화시키게 한 것이다. 2 is a partial cross-sectional view of the front view of the present invention, with the center yoke 11 in the middle of the inner side of the outer outer body 10, 10a of the traction articulation joint, and connecting the yoke 12, 12a with the cross bearing 13; And the power transmission shafts 15 and 15a formed with the splines in the insertion holes 14 and 14a having splines formed at the rear of both yokes 12 and 12a to be moved. The spring 21 is installed inside both caps 20 and 20a between the two power transmission shafts 15 and 15a and the yoke 12 and 12a. 3 is a cross-sectional view of the main portion of the present invention, and FIG. 4 is a cross-sectional view of the refraction state of the refraction state viewed from the plane of the present invention. 12) The power transmission shafts 15, 15a and both yokes 12, 12a are connected by splines by the elasticity of the springs 21 installed in both caps 20, 20a at the rear of the 12a. Since both yokes 12 and 12a are moved along the spline, the center yoke 11 is always moved to the center and kept horizontal at all angles, so that the ends of both yokes 12 and 12a are always at an angle. Since the load is uniformly applied, the breakage of the articulation joint can be minimized even when the angle of refraction is increased, and the connecting rod connecting the towbar 30 to the lower portion of the outer body 10 of the front yoke 12 ( 31) is bonded to the pin 32, so the angle of refraction It will largely be a thereby minimizing the damage of the each joint does not to apply excessive force to each yoke.
