Towing).

여기서, 상기한 차량이 정차하거나 출발하게 되면, 견인고리(51)와 견인후크(50)가 부딪혀서 충격 및 소음이 발생되는 바, 이를 방지하기 위하여 도5에 도시된 바와 같이 견인후크(50)에 힌지(54)로 설치되어 견인고리(51)와 밀착되는 홀 더(55)와, 상기한 홀더(55)를 공기압으로 밀어 견인고리(51)에 밀착되도록 하는 에어 챔버(56) 및 로드(57)로 이루어져 있다.In this case, when the vehicle stops or starts, the tow hook 51 and the tow hook 50 collide with each other, so that impact and noise are generated. To prevent this, the tow hook 50 is shown in FIG. The holder 55 which is installed by the hinge 54 to be in close contact with the traction ring 51, and the air chamber 56 and the rod 57 which push the holder 55 to air pressure to be in close contact with the traction ring 51. )

즉, 상기한 에어챔버(56)의 힘에 의해 로드(57)가 항상 홀더(55)를 밀어서 견인고리(51)와 견인후크(50)가 밀착되도록 함으로써, 차량의 정차, 출발 시 견인고리(51)와 견인후크(50)의 충돌 및 소음을 방지할 수 있게 되는 것이다.That is, the rod 57 always pushes the holder 55 by the force of the air chamber 56 so that the traction ring 51 and the traction hook 50 come into close contact with each other. 51) will be able to prevent the collision and noise of the towing hook (50).

그러나, 상기한 바와 같이 견인고리와 견인후크를 밀착시켜 차량의 정차 및 출발 시 충돌과 소음을 방지하기 위하여 별도의 에어챔버와 로드등을 설치하게 되면 그 구성이 매우 복잡하고 부피가 크며 설치가 어렵게 되는 문제점이 있다.However, as described above, if a separate air chamber and a rod are installed in close contact with the towing hook and the towing hook to prevent collisions and noises when the vehicle is stopped and started, the configuration is very complicated, bulky, and difficult to install. There is a problem.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 견인고리와 견인후크의 밀착을 위한 구성을 단순하게 하면서도 견인고리와 견인후크의 밀착을 견고하게 하여 차량의 정차 및 출발 시 견인후크와 견인고리의 충돌과 소음 발생을 방지할 수 있는 트레일러용 견인후크의 충격완충장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, while simplifying the configuration for the close contact between the towing hook and the towing hook, and to firmly adhere to the towing hook and the towing hook and tow hook at the stop and start of the vehicle. The present invention provides a shock absorber for a trailer towing hook that can prevent collision of a towing ring and noise generation.

상기한 목적을 실현하기 위하여 본 발명은, 견인후크에서 견인고리가 삽입되는 부분에 회전축으로 설치되어 회전 운동 가능함과 아울러 견인고리가 끼워져 연동하도록 끼움부가 형성된 회전링과, 상기한 회전링이 관통된 상태에서 이동 가능하도록 견인후크에 설치됨과 아울러 점성이 높은 유체가 충진된 챔버와, 상기한 챔버의 내부에 위치되고 회전링의 회전과 연동하도록 회전링에 고정 설치되어 회전 시 감압시켜 천천히 회전하도록 다수의 구멍이 형성된 감압판으로 구성함을 특징으로 한다.In order to achieve the above object, the present invention, the rotation ring is installed in the traction hook portion is inserted into the traction ring is capable of rotational movement and the traction ring is fitted with the rotary ring formed to interlock with the traction ring, the rotary ring is penetrated It is installed in the traction hook to be movable in the state, and the chamber filled with highly viscous fluid, and is fixed to the rotating ring located inside the chamber and interlocked with the rotation of the rotating ring, so that it rotates slowly by reducing the pressure when rotating. Characterized in that composed of a pressure-sensitive plate formed with a hole.

도1과 도2는 본 발명에 따른 트레일러용 견인후크의 충격완충장치를 도시한 정면도와 분해 사시도로서, 견인후크(50)에서 견인고리(51)가 삽입되는 부분에 회전축(1)으로 설치되어 회전 운동 가능함과 아울러 견인고리(51)가 끼워져 연동하도록 끼움부(2)가 형성된 회전링(3)과, 상기한 회전링(3)이 관통된 상태에서 이동 가능하도록 견인후크(50)에 설치됨과 아울러 점성이 높은 유체가 충진된 챔버(4)와, 상기한 챔버(4)의 내부에 위치되고 회전링(3)의 회전과 연동하도록 회전링(3)에 고정 설치된 감압판(5)으로 이루어져 있다.1 and 2 are a front view and an exploded perspective view showing the shock absorber of the trailer towing hook according to the present invention, is installed as a rotating shaft (1) in the towing hook 51 is inserted in the towing hook (50) Rotating ring (3) having a fitting portion (2) formed so that the traction ring 51 is interlocked with the traction ring (51), and installed in the traction hook (50) to be movable in the state in which the rotating ring (3) is penetrated. And a chamber 4 filled with a highly viscous fluid, and a pressure reducing plate 5 positioned inside the chamber 4 and fixed to the rotating ring 3 so as to cooperate with rotation of the rotating ring 3. consist of.

즉, 상기한 회전링(3)이 견인고리(51)에 의해 회전축(1)을 중심으로 회전을 하게 되면 감압판(5)이 챔버(4) 내부에서 이동하는 바, 상기한 챔버(4) 내부에 충진된 유체에 의해 감속되면서 견인고리(51)와 견인후크(50)의 급격한 충돌을 방지할 수 있게 되는 것이다.That is, when the rotary ring 3 is rotated about the rotating shaft 1 by the traction ring 51, the pressure reducing plate 5 moves in the chamber 4, the chamber 4 While being decelerated by the fluid filled therein, it is possible to prevent a sudden collision between the traction ring 51 and the traction hook 50.

상기한 감압판(5)에는 다수의 구멍(6)이 형성되어 유체가 통과할 수 있게 되는 바, 상기한 구멍(6)의 직경 및 숫자에 의해 감압되는 힘이 조절되고, 이를 통해 트레일러(T)의 중량에 따라 적절한 조절이 가능하게 된다.A plurality of holes 6 are formed in the decompression plate 5 to allow the fluid to pass therethrough, and thus the force to be decompressed by the diameter and the number of the holes 6 is adjusted, and thus the trailer T Can be appropriately adjusted according to the weight of the

상기한 바와 같은 본 발명의 작용 효과를 설명하면 차량에 트레일러(T)를 연결하기 위해서, 트레일러(T)의 견인고리(51)를 견인후크(50)에 삽입한 후 상기한 견인고리(51)를 끼움부(2)에 끼우게 된다.Referring to the operation and effect of the present invention as described above, in order to connect the trailer (T) to the vehicle, the towing ring 51 of the trailer (T) is inserted into the towing hook (50) and then the towing ring (51). It will be fitted to the fitting (2).

끼움부(2)에 견인고리(51)를 끼운 상태에서 견인후크(50)의 록킹바(53)를 잠그면 트레일러(T)의 연결이 완료된 상태인 바, 이 상태에서 차량이 주행을 하게 되 면 견인고리(51)가 회전링(3)에 지지되어 있게 된다.When the locking bar 53 of the towing hook 50 is locked while the tow hook 51 is inserted into the fitting portion 2, the connection of the trailer T is completed. When the vehicle runs in this state, Traction ring 51 is supported by the rotary ring (3).

즉, 차량이 정차하게 되면 상기한 차량은 정지하는 상태에서 트레일러(T)는 관성에 의해 차량측으로 계속 전진하려고 하는 바, 상기한 관성에 의해 회전링(3)이 견인고리(51)와 함께 도3에 도시된 바와 같이 반시계방향으로 이동을 하게 된다.That is, when the vehicle stops, the trailer T tries to move forward to the vehicle side by the inertia while the vehicle stops, and the rotary ring 3 moves together with the towing ring 51 by the inertia. As shown in Fig. 3, it moves in the counterclockwise direction.

회전링(3)이 반시계 방향으로 이동하게 되면 상기한 챔버(4) 내부에 위치된 감압판(5)이 회전링(3)과 함께 반시계방향으로 이동하게 되는 바, 상기한 이동 시 챔버(4) 내부에 충진된 유체에 의해 저항을 받게 되면서 회전링(3)의 이동이 매우 천천히 이루어지게 된다.When the rotary ring 3 moves counterclockwise, the pressure reducing plate 5 located inside the chamber 4 moves counterclockwise together with the rotary ring 3. (4) As the resistance is received by the fluid filled therein, the rotation ring 3 moves very slowly.

즉, 상기한 유체에 의해 감압판(5)의 이동에 저항이 발생되고 이로 인해 회전링(3)과 감압판(5)이 천천히 이동하고, 상기한 회전링(3)의 끼움부(2)에 끼워진 견인고리(트레일러)가 천천히 이동하게 되는 것이다.That is, a resistance is generated in the movement of the pressure reducing plate 5 by the fluid, which causes the rotary ring 3 and the pressure reducing plate 5 to move slowly, and the fitting portion 2 of the rotary ring 3 is moved. The towing ring (trailer) inserted in it will move slowly.

회전링(3)과 여기에 끼워진 견인고리(51)가 천천히 이동하게 되면 상기한 견인고리(51)와 견인후크(50)와의 충돌이 발생되지 않거나 매우 약한 힘으로 발생되기 때문에, 견인고리(51)와 견인후크(50)간의 충돌에 따른 진동이나 소음등이 발생되지 않게 된다.When the rotary ring 3 and the traction ring 51 inserted therein are slowly moved, the collision between the traction ring 51 and the traction hook 50 does not occur or is generated with a very weak force. ) And the vibration of the collision between the towing hook 50 is not generated.

물론, 상기한 차량이 출발할 때에는 회전링(3)이 시계방향으로 회전하는 힘을 받게 되는 바, 상기한 감압판(5)에 의해 감속되면서 충돌등이 방지된다.Of course, when the vehicle starts, the rotary ring 3 receives a force that rotates in a clockwise direction, and the collision is prevented while being decelerated by the decompression plate 5.

이상과 같이 본 발명은 견인후크에 유압에 의해 감속되도록 회전링을 설치함 으로써, 매우 단순한 구성으로도 견인후크와 견인고리와의 충돌 및 소음을 감소시킬 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of reducing collision and noise between the traction hook and the traction ring by installing a rotary ring to reduce the speed by hydraulic pressure in the traction hook.
