종래 트랙터는 양측으로 관리기나 각종 작업기를 장착하여 작업하거나 견인을 하게 되며, 필요에 따라서 트랙터는 일측으로 관리기나 각종 작업기를 장착하여 작업하거나 견인을 하게 되는데, 이때 관리기 및 작업기에 동력이 필요한 경우에는 트랙터의 엔진동력을 출력시켜 이를 로터리 유니버설 죠인트로 연결시킴으로서 관리기 및 작업기에 동력을 전달하게 된다.Conventional tractors work or tow by attaching a manager or various work machines to both sides, and tractors are equipped with a manager or various work machines to one side to work or tow, as needed. It outputs the engine power of the tractor and connects it to the rotary universal joint to transmit power to the manager and workman.

그러나 이때 유니버설 죠인트의 동력 연결이 죠인트 조합(4)(4')과 같이 단일 죠인트 연결에 의해 동력을 전달하므로 작업기를 이용한 작업 및 견인작업을 할때 죠인트 조합 연결에 의해 꺽임각도가 적어 동력전달기 많은 부하가 발생되고 부하를 견딜 수 없게 된 작업기와 트랙터에는 무리한 부하가 걸려 떨리게 되며, 동력전달계에 이러한 과부하가 전달된 밋숀과 기어장치 및 엔진에 무리가 가서 밋숀과 기어파손의 원인이 되었고 엔진고장의 원인이 되었으며 작업능률을 저하시키는 결점을 갖고 있었다.However, since the power connection of the universal joint transmits power by a single joint connection as in the joint combination (4) (4 '), when the work and towing work using a working machine are carried out, the angle of bending is small by the joint combination connection. A heavy load is generated and the tractor and the tractor that cannot tolerate the load are subjected to excessive load and tremble. The overload is transmitted to the transmission system, and the engine and the gear unit and the engine are overwhelmed, causing the failure and gear failure. It has been a cause of and has the disadvantage of degrading work efficiency.

Its purpose is to reduce the load on the gear system so as not to overload it.

이하 본 발명의 실시예를 첨부시킨 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings an embodiment of the present invention.

작업기의 축(16)과 연결되는 축결합부(13)를 갖고 상기 축결합부(13)의 양측핀 몸체(11)에 핀(12)을 꽂아 와셔(14)와 고정핀(15)으로 고정되는 더블핀 요우크(3)와 스파이더 조합(9)으로 연결되는 죠인트 조합(4)이 죠인트 조합(4')과 스파이터 조합(9')으로 연결되며 트랙터 쪽으로 축(16)을 통하여 엔진의 동력을 전달 받으며 상기 더블핀 요우크(3)와 같은 구조의 더블핀 요우크(3')에 의해 엔진의 동력을 작업기에 전달하는 죠인트에 있어서, 상기 더블핀 요우크(3)와 죠인트 조합(4)이 각각의 스파이더 조합(9)(9')과 상기 스파이더 조합(9)(9') 사이의 더블 꺽임장치(2)에 의해 연결되도록 구성한다.It has a shaft coupling portion 13 connected to the shaft 16 of the working machine and the pin 12 is inserted into both pin body 11 of the shaft coupling portion 13 and fixed with the washer 14 and the fixing pin 15. The joint combination (4), which is connected to the double pin yoke (3) and the spider combination (9), is connected to the joint combination (4 ') and the spider combination (9'), and the power of the engine through the shaft (16) toward the tractor. In the joint for transmitting the power of the engine to the work machine by the double pin yoke (3 ') of the same structure as the double pin yoke (3), the double pin yoke (3) and the joint combination (4) ) Is connected by a double bending device 2 between each spider combination 9, 9 ′ and the spider combination 9, 9 ′.

이때 더블꺽임장치(2)는 스파이더 조합(9)에 의해 더블핀 요우크(3)와 연결되며 상기 더블핀 요우크(3)의 일측으로 볼(8')을 갖고, 상기 스파이더 조합(9)은 연결대(10)에 의해 연결되는 동시에 반대쪽의 스파이더 조합(9')에 의해 죠인트 조합(4)과 연결되도록 하는 연결대(10')가 연결된 후 중앙에 가이드홈(5a)을 갖는 가이드 연결판(5)과, 상기 죠인트 조합(4)의 일측으로 볼(8)과 대향되는 볼(8')을 구성한다.In this case, the double bending device 2 is connected to the double pin yoke 3 by the spider combination 9 and has a ball 8 'at one side of the double pin yoke 3, and the spider combination 9 The guide connecting plate having a guide groove 5a at the center after connecting the connecting rod 10 'which is connected by the connecting rod 10 and connected to the joint combination 4 by the opposite spider combination 9' 5) and a ball 8 'opposed to the ball 8 on one side of the joint combination 4.

그리고 상기 가이드 연결판(5)의 가이드홈(5a)에 삽입되어 더블 죠인트(1)가 꺽임에 따라 어느방향으로든 이동되는 원판(6)과 일체로 되며 볼(8)(8')이 양측에 삽입되어 꺽어지는 각을 잡아 부하를 견디도록 하는 볼 연결구(7)로 이루어진다.And it is inserted into the guide groove (5a) of the guide connecting plate (5) is integral with the disk (6) which is moved in any direction as the double joint (1) is bent and the balls (8) (8 ') on both sides It consists of a ball connector (7) to withstand the load by inserting a bending angle.

즉, 볼 연결구(7)의 양측으로 볼(8)(8')이 삽입되어져 더블핀 요우크(3)와 죠인트 조합(4)으로 연결되며 스파이더 조합(9)(9')을 통하여 가이드 연결판(5)의 연결대(10)에 의해 이중으로 연결시키고 꺽임각도와 방향에 따라 원판(6)이 가이드홈(5a)에서 슬라이드 되도록 구성한다.That is, balls 8 and 8 'are inserted into both sides of the ball connector 7 to be connected to the double pin yoke 3 and the joint combination 4 and guide connection through the spider combination 9 and 9'. It is connected so as to be connected in a double by the connecting table 10 of the plate (5) and the disc 6 is configured to slide in the guide groove (5a) according to the bending angle and direction.

이와 같은 구성으로 이루어진 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention made of such a configuration in detail as follows.

트랙터의 엔진동력이 밋숀과 기어장치 및 축(16)을 통하여 더블핀 요우크(3')에 전달되면 죠인트 조합(4')에 의한 죠인트 조합(4)으로 전달된 후 더블꺽임장치(2)를 통하여 더블핀 요우크(3)의 축(16)에 작업기에 동력을 전달시켜 작업 및 견인을 하도록 하는 것으로 논과 밭등의 이랑 갈이와 작업장에서 회전을 할때 및 견인시에는 작업기를 지면으로부터 들어올려 견인하게 될때 더블핀 요우크(3)(3') 사이에 꺽이게 된다.When the engine power of the tractor is transmitted to the double pin yoke (3 ') via the traction, gear and shaft (16), it is transferred to the joint combination (4) by the joint combination (4') and then the double bending device (2) It is used to transfer the power to the shaft 16 of the double pin yoke 3 to the work and to tow the work. When towing it is bent between the double pin yokes (3) (3 ').

그러나 종래에는 더블핀 요우크(3)(3') 사이에 죠인트 조합(4)(4')으로 1단계만 연결되었으므로 꺽임각이 적어 엔진이나 기어장치 및 밋숀에 무리를 주었으나 본 발명은 더블꺽임장치(2)에 의해 작업기를 회전시킬때나 견인시 들어올리때에 꺽임각도를 더욱 크게 가져가도록 하여 꺽임시 더블 요우크(1)에 부하가 걸리지 않게 된다.However, in the related art, since only one stage is connected by a joint combination (4) (4 ') between the double pin yoke (3) (3'), the bending angle is small, and the engine, the gear device, and the transmission are excessive. When the work machine is rotated by the bending device 2 or lifted during towing, the bending angle is made larger so that the load is not applied to the double yoke 1 during the bending.

즉, 종래에는 더블핀 요우크(3')와 죠인트 조합(4')에 의해 1차로 꺽인후 죠인트 조합(4)과 더블핀 요우크(3)의 결합으로 2차 꺽임이 이루어졌으나 본 발명은 더블핀 요우크(3')와 죠인트 조합(4')에 의해 1차로 꺽인후 죠인트조합(4)과 스파이더 조합(9')으로 연결된 더블꺽임장치(2)에 의해 2차로 꺽임 다음 더블꺼임장치(2)와 스파이더 조합(9)으로 연결된 더블핀 요우크(3)에 의해 3차로 꺽이게 되므로 더욱 큰 꺽임각을 얻을 수 있게 되어 부하를 감소시키는 것이다.That is, in the related art, after the first bending by the double pin yoke 3 'and the joint combination 4', the second bending is performed by the combination of the joint combination 4 and the double pin yoke 3, but the present invention 1st bending by double pin yoke (3 ') and joint combination (4'), then 2nd bending by double bending device (2) connected by joint combination (4) and spider combination (9 ') Since the third pin is bent by the double pin yoke (3) connected by the combination of the spider (9) and the spider (9), a larger angle of bending can be obtained, thereby reducing the load.

이때 죠인트 조합(4)과 더블꺽임장치(2)가 꺽일때 볼(8')은 볼 연결구(7)에서 회전작용이 이루어지며 원판(6)은 꺽임방향과 반대방향으로 이동되며 가이드 연결판(5)의 가이드홈(5a)을 타고 이동될때 볼 연결구(7)에서 볼(8)이 회전작용을 이루면서 더블핀 요우크(3)도 꺽이는 이중꺽임작용을 이루게 된다.At this time, when the joint combination (4) and the double bending device (2) is bent, the ball (8 ') is rotated at the ball connector (7), and the disc (6) is moved in the opposite direction to the bending direction and the guide connecting plate ( 5) When the ball is moved in the guide groove (5a) of the ball connector (7) is a double pin yoke (3) also make a double action while rotating the ball (8).

즉, 스파이더 조합(9)(9')은 더블 연결장치(2)에서 더블핀 요우크(3)와 죠인트 조합(4)의 연결성과 꺽임각도를 유지하고, 볼(8)(8')과 원판96) 및 가이드 연결판(5)은 이중꺽임시 꺽임을 부드럽게 하여 가이드 연결판(5)이 꺽이면서 더블핀 요우크(3)가 꺽이도록 하는 것이다.That is, the spider combination 9, 9 ′ maintains the connectivity and bending angle of the double pin yoke 3 and the joint combination 4 in the double coupling device 2, and the balls 8, 8 ′ and The disc 96 and the guide connecting plate 5 smooth the bending when double bending so that the double pin yoke 3 is bent while the guide connecting plate 5 is bent.

상술한 바와 같이 본 발명은 종래 죠인트 조합에 의한 꺽임 및 동력전달구조에 비해 더블꺽임장치에 의해 이중꺽임구조에 의해 작업기를 이용한 작업 및 견인시 꺽임을 크게 하고 관리기나 각종 작업기등을 견고하게 연결시켜 작업기의 부하를 해소시킴으로서 작업기와 트랙터의 기어장치와 밋숀 및 엔진에 무리를 주지 않아 트랙터의 수명을 연장시켜 줌은 물론 고장과 파손의 원인을 해소시켜 보다 안정된 영농작업을 할 수가 있는 매우 유용한 발명인 것이다.As described above, in the present invention, the double bending device is used to double the bending and power transmission structure by the joint combination, and the double bending structure allows the working and towing during the towing to be firmly connected to the manager or various working machines. It is a very useful invention that can extend the life of the tractor by eliminating the load on the work machine and not to put pressure on the gear device, the traction and the engine of the work machine and the tractor, and to solve the cause of breakdown and damage and to perform more stable farming work. .
