3윤축 철도차량의 견인장치{tow device of 3 wheel axial railway cars} Tow device of 3 wheel axial railway cars}

본 발명은 3윤축 철도차량의 견인장치에 관한 것으로, 더욱 상세하게는 센타 피봇을 대차의 상부에 설치할 공간이 없는 3윤축 대차인 경우, 대차의 하부에 별도의 견인장치를 설치하여 대차의 견인 및 제동력을 차체에 전달되게 하는 3윤축 철도차량의 견인장치에 관한 것이다.The present invention relates to a traction device for a three-wheeled railway vehicle, and more particularly, in the case of a three-wheeled truck with no space for installing the center pivot on the upper portion of the bogie, a separate traction apparatus is installed at the lower portion of the bogie to pull out the bogie and It relates to a traction device of a three-wheeled railway vehicle that allows braking force to be transmitted to the body.

일반적으로 철도차량의 대차는 차체와 레일 사이에 있으며, 윤축에 의해 레일 위를 주행하는 중요한 부분이다. 그리고 대차의 구성은 대차 프레임과, 윤축, 베어링박스 등 기타 주요부품이 설치되어 있다. 그리고 철도차량에는 통상적으로 2윤축를 구비하는 대차가 많이 사용된다.In general, the trolley bogie is located between the body and the rail and is an important part of traveling on the rail by the wheel. And the bogie frame is equipped with bogie frame, wheelset, bearing box and other major parts. And a railroad car is usually used a lot of trucks with two wheels.

상기 2윤축 대차(10)는 도 1에 도시된 바와 같이 전방 및 후방에 선두 윤축(21) 및 후미 윤축(22)이 각각 설치되고, 상기 선두 윤축(31)및 후미 윤축(32)에는 이 윤축(31, 32)을 회전시키는 구동장치(40) 및 제동장치(50)가 각각 장착되며, 상기 선두 윤축(31)및 후미 윤축(32) 사이에 위치하는 2윤축 대차(10)의 상부 중심부에는 센타 피봇(60)이 상방으로 돌출되게 형성되어 이루어진다.As shown in FIG. 1, the two wheelset trolley 10 has a front wheelset 21 and a rear wheelset 22 installed at the front and the rear, respectively, and the wheel wheel 31 and the rear wheelset 32 have this wheelset. A driving device 40 and a braking device 50 for rotating the 31 and 32 are mounted, respectively, and in the upper center portion of the two wheelset bogie 10 positioned between the first wheelset 31 and the rear wheelset 32. The center pivot 60 is formed to protrude upward.

상기 센터 피봇(60)은 2윤축 대차(10)와 차체(20)간을 연결하여 차체(20)에 견인 및 제동력을 전달하고, 철도차량이 곡선선로에 진입할 경우에는 2윤축 대차(10)가 회전하여 원활한 주행을 할 수 있도록 한다.The center pivot 60 connects the two wheelbase bogie 10 and the vehicle body 20 to transmit the traction and braking force to the vehicle body 20, and when the railway vehicle enters a curved track, the two wheelset bogie 10 is connected. Rotate to allow smooth running.

그러나 종래 2윤축 대차는 상방으로 돌출된 센터 피봇을 통해 차체와 연결되어 차체에 견인 및 제동력을 전달하였으나, 기관차 등에 정착되는 3윤축 대차는 선두 윤축 및 후미 윤축 사이에 중간 윤축이 추가로 설치되고, 대차의 중심부가 되는 중간 윤축에도 구동 및 제동장치가 추가로 장착됨으로써, 이러한 구조에서는 센터 피봇을 설치할 공간이 협소하여 견인장치인 센터 피봇의 설치가 불가능하였다. However, the conventional two-wheeled trolley is connected to the vehicle body through a center pivot protruding upwards to transmit the traction and braking force to the vehicle body, but in the three-wheeled trolley which is fixed to the locomotive, an intermediate wheelset is additionally installed between the leading wheel and the rear wheel. Since the driving and braking devices were additionally mounted on the intermediate wheelset, which is the center of the trolley, the space for installing the center pivot was narrow in such a structure, and thus the installation of the center pivot, which is a traction device, was impossible.

그리고 차체의 한정된 대차 설치공간으로 인해 대차의 길이 증대는 불가능하지만, 만약 3윤축 대차에 센터 피봇을 설치하기 위해 대차의 길이를 증대할 경우에는 대차의 중량이 증대되고 대차 길이의 증대로 인해 윤축간에 축거가 증대되어 차륜이 과다하게 마모되는 문제점이 발생하였다.And it is impossible to increase the length of the bogie due to the limited bogie installation space of the body, but if the bogie length is increased to install the center pivot on the 3-wheel bogie, the weight of the bogie increases and the bogie's length increases. The wheelbase has been increased, causing the wheel to wear excessively.

이에 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 3윤축 대차의 상부에 견인장치인 센터 피봇을 설치하지 않고, 별도의 공간에 견인장치를 설치하여 대차가 차체에 견인 및 제동력을 전달하게 하는 것을 제공하는 것이다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to install a towing device in a separate space without a center pivot, which is a towing device on the upper portion of the three wheeled bogie, the truck is towed to the vehicle body And to provide braking force.

상기와 같은 목적을 달성하기 위한 본 발명은 3윤축 대차와 차체 사이에 설치되는 철도차량용 견인 장치로서, 상기 3윤축 대차의 하부에 하방으로 돌출되도록 형성되어 선두 윤축 및 중간 윤축 사이에 위치는 대차 피봇과, 상기 차체의 하부에 상기 대차 피봇과 대응하는 높이를 가지도록 형성되는 차체 피봇과, 상기 대차 피봇의 단부에 일단이 연결되고 타단이 상기 차체 피봇의 단부에 연결되는 견인 로드를 포함하여 이루어지는 것을 특징으로 한다.The present invention for achieving the above object is a railway vehicle traction device installed between the three wheelbase bogie and the vehicle body, is formed to protrude downward in the lower portion of the three wheelset bogie is positioned between the leading wheelset and the middle wheelset pivot pivot And a traction rod formed at a lower portion of the vehicle body so as to have a height corresponding to the balance pivot, and a traction rod having one end connected to an end of the bogie pivot and the other end connected to an end of the body pivot. It features.

이상에서 설명한 바와 같이 본 발명은 센타 피봇을 상부에 설치할 공간이 없는 3윤축 대차인 경우, 대차의 하부 및 차체의 하부에 각각 대차 피봇 및 차체 피봇을 형성하고, 이를 견인 로드로 연결하여 대차의 견인 및 제동력을 차체에 전달되게 함으로써, 3윤축 대차가 대차의 길이 증대 없이 차체의 한정된 대차 설치공간 되므로, 대차의 길이 증대로 인한 중량 증가 및 차체와의 인터페이스 문제를 극복할 수 있는 효과가 있다.As described above, in the present invention, in the case of a three-wheeled trolley having no space for installing the center pivot, the trolley pivot and the body pivot are formed at the lower side of the trolley and the lower side of the body, respectively. And by allowing the braking force to be transmitted to the vehicle body, the three-wheeled trolley bogie becomes a limited bogie installation space of the vehicle body without increasing the length of the bogie, there is an effect that can overcome the weight increase and interface problems with the body due to the increase in the bogie length.

또, 대차 길이 증대로 인한 윤축간에 축거 증대로 발생할 수 있는 차륜의 과다 마모도 방지할 수 있는 효과가 있다.
In addition, there is an effect that can prevent excessive wear of the wheel that may occur due to the increase in wheelbase between wheels due to the increase in the length of the bogie.

It is formed to have.

상기와 같이 구성된 본 고안의 작용 상태를 설명하면 다음과 같다.Referring to the working state of the present invention configured as described above are as follows.

도면에서 도시된 바와 같이 대차 피봇(111)은 3윤축 대차(110)에 장착된 선두 윤축(210)과 중간 윤축(220) 사이 공간에 위치하여 3윤축 대차(110)의 하부에 설치되고, 또 차체 피봇(121)은 차체(120)의 하부에 상기 대차 피봇(111)과 대응하는 높이를 가지도록 형성됨으로써, 3윤축 대차(110)의 길이 증대가 불필요하고, 선두 윤축(210)과 중간 윤축(220)에 간섭을 받지 않으면서 2윤축을 가진 대차의 센터 피봇을 대신하게 된다.As shown in the figure, the trolley pivot 111 is located in the space between the first wheelset 210 and the intermediate wheelset 220 mounted on the three wheelset bogie 110 and is installed in the lower portion of the three wheelset bogie 110, and The body pivot 121 is formed at a lower portion of the body 120 to have a height corresponding to that of the trolley pivot 111, thereby increasing the length of the three wheelset trolley 110 without the need for an increase in the length of the three wheelset trolleys 110 and the intermediate wheelset 210 and the intermediate wheelset. It will replace the center pivot of the bogie with two wheelsets without being interfered with (220).

그러므로 3윤축 대차(110)가 주행하거나 정지하게 되면, 3윤축 대차(110)와 차체(120)를 연결한 견인 로드(130)에 의해 차체(120)도 주행하거나 멈추게 된다.Therefore, when the three wheelbase trolley 110 runs or stops, the vehicle body 120 also travels or stops by the towing rod 130 connecting the three wheelset trolley 110 and the vehicle body 120.

이때, 3윤축 대차(110)와 차체(120)간을 연결하는 견인 로드(130)는 3윤축 대차(110)의 견인 및 제동력을 차체(120)에 전달하면서, 견인 로드(130)의 양단에 형성된 부싱 부재(140)가 3윤축 대차(110)와 차체(120) 간에 회전 및 수직변위를 탄성 부재(143)를 통해 흡수함으로써, 차체(120)의 하부에 설치된 3윤축 대차(110)가 급격하게 회전하거나 상하로 이동하는 것을 최소화하게 된다.At this time, the traction rod 130 connecting the three wheelbase bogie 110 and the vehicle body 120 transmits the traction and braking force of the three wheelset bogie 110 to the vehicle body 120, and is connected to both ends of the traction rod 130. The formed bushing member 140 absorbs the rotation and vertical displacement between the three wheelset bogie 110 and the vehicle body 120 through the elastic member 143, so that the three wheelset bogie 110 installed in the lower portion of the vehicle body 120 suddenly. Rotation or movement up and down is minimized.

또, 고정부재(150)는 견인 로드(130)의 양단을 대차 피봇(111) 및 차체 피봇(121)의 단부에 각각 고정함으로써, 견인로드(130)의 양단이 대차 피봇(111) 및 차체 피봇(121)의 단부에서 이탈되는 것을 방지한다.In addition, the fixing member 150 fixes both ends of the pull rod 130 to the end portions of the bogie pivot 111 and the body pivot 121, so that both ends of the pull rod 130 are the bogie pivot 111 and the body pivot. It prevents from leaving at the end of 121.

또한, 대차 피봇(111) 및 차체 피봇(121)의 단부에 형성된 경사면(111a, 121a)과 부싱 부재(140)의 내부 부싱에 형성된 경사면(142b)은 3윤축 대차(110)와 차체(120) 간에 수직 변위가 발생할 때, 대차 및 차체 피봇(111, 121)의 단부와 부싱 부재(140) 사이에 미끄러짐을 방지하게 된다.
In addition, the inclined surfaces 111a and 121a formed at the ends of the bogie pivot 111 and the vehicle body pivot 121 and the inclined surfaces 142b formed in the inner bushing of the bushing member 140 are the three wheelbase bogie 110 and the vehicle body 120. When a vertical displacement occurs in the liver, slippage is prevented between the end portions of the bogie and the body pivots 111 and 121 and the bushing member 140.
