철도차량용 현가장치{suspension device for rail vehicles}Suspension device for rail vehicles

본 발명은 철도차량용 현가장치에 관한 것으로, 더욱 상세하게는 대차에 볼스터로 지지되는 차체의 상하진동을 전후진동으로 변환하여 감쇄하기 위한 철도차량용 현가장치에 관한 것이다.The present invention relates to a suspension device for a railroad car, and more particularly, to a railroad car suspension device for converting the upper and lower vibrations of a vehicle body supported by a bolster into front and rear vibrations to attenuate them.

일반적으로 철도차량은 선로 위를 운행할 목적으로 제조한 차량으로서, 승객을 싣는 차체와, 윤축을 통해 철도차량의 주행하게 하는 대차와, 대차를 구성하는 부재중 하나로 차체 및 대차 사이를 연결하여 대차의 견인력 및 제동력을 차체에 전달하는 볼스터로 이루어진다. In general, a railway vehicle is a vehicle manufactured for the purpose of running on a track, and is connected to the vehicle body and the bogie by connecting one of the body that carries the passenger, the bogie that allows the railway vehicle to run through the wheel, and the members constituting the bogie. It consists of a bolster that transmits traction and braking force to the body.

그리고 철도차량에는 차체와 대차 사이에 발생하는 진동과 소음을 차체로 전달되는 것을 감쇠하여 차체에 승차감을 좋게 하기 위해 각종 현가장치가 설치된다.In addition, the railway vehicle is provided with various suspension devices in order to attenuate the vibration and noise generated between the vehicle body and the bogie to the vehicle body to improve the ride comfort.

도 1은 종래의 철도차량용 현가장치를 도시한 정면도로서, 도면에 도시된 바와 같이 차체(10)와 대차(20) 사이에는 양측으로 각각 수직을 이루는 댐퍼(30)가 설치되고, 이 댐퍼(30)는 각각 상하방향의 길이를 신축을 통해 차체(10)의 상하진동 및 좌우회전(롤링)을 감쇄하였다.1 is a front view illustrating a conventional railway vehicle suspension device, and as shown in the drawing, a damper 30 is provided between the vehicle body 10 and the bogie 20 to be perpendicular to each side, respectively, and the damper 30 is provided. ) Attenuated the vertical vibration and the left-right rotation (rolling) of the vehicle body 10 through the expansion and contraction of the length in the vertical direction.

그러나 이러한 댐퍼는 차체와 대차 간에 수직으로 설치되기 때문에, 보통의 철도차량은 차체와 대차 간에 공간이 충분하여 수직의 댐퍼를 설치할 수 있지만, 저상형 트램이나 대차의 볼스터를 통해 차체와 결합하는 틸팅 차량은 차체와 대차 간에 공간이 협소하여 수직의 댐퍼를 설치할 수 없는 문제점이 있었다.However, since these dampers are installed vertically between the body and the bogie, a normal railway vehicle has enough space between the body and the bogie to install a vertical damper, but a tilting vehicle that is coupled to the body via a low-rise tram or boulder bolster. There was a problem that the vertical damper can not be installed because the space is narrow between the body and the bogie.

이에 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 저상형 트램이나 틸팅 차량과 같이 차체와 대차, 차체와 볼스터 사이의 공간이 매우 협소할 경우에도 댐퍼를 통해 차체의 상하진동 및 차체의 좌우회전(롤링)을 감쇄하도록 하는 것을 제공하는 것이다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention, even when the space between the body and the bogie, the body and the bolster, such as low-rise tram or tilting vehicle is very narrow, the upper and lower parts of the body through the damper It is to provide to reduce the vibration and the left and right rotation (rolling) of the vehicle body.

도 2, 3에 도시된 바와 같이 본 발명은 대차(20)의 볼스터(40)로 지지되는 차체(10)의 상하진동을 전후진동으로 변환하기 위한 철도차량용 현가장치로서, 먼저 대차(20)의 횡방향으로 연장되도록 볼스터(40)의 내측에 회전가능하도록 설치되는 힌지축(100)이 형성된다.As shown in Figures 2 and 3, the present invention is a suspension device for railway vehicles for converting the upper and lower vibrations of the vehicle body 10 supported by the bolster 40 of the trolley 20 into front and rear vibration, first of the trolley 20 A hinge shaft 100 is rotatably installed inside the bolster 40 so as to extend laterally.

그리고 상기 볼스터(40)의 양측에 돌출된 힌지축(100)의 양단에는 서로 대칭을 이루도록 제1링크(200)가 각각 고정되되, 상기 제1링크(200)는 상기 힌지축(100)의 양단에 각각 일단이 고정되어 대차(20)의 길이방향으로 형성되는 제1연결편(210)과, 이 제1연결편(210)에 대해 대차(20)의 상방으로 형성되는 제2연결편(220)으로 이루어진다.The first link 200 is fixed to both ends of the hinge shaft 100 protruding from both sides of the bolster 40 so as to be symmetrical with each other, and the first link 200 has both ends of the hinge shaft 100. One end is fixed to the first connecting piece 210 formed in the longitudinal direction of the trolley 20, and the second connecting piece 220 formed above the trolley 20 with respect to the first connecting piece 210. .

상기 제1링크(200)의 제2연결편(220)은 상기 제1연결편(210)의 상하방향회전이 전후방향회전으로 전환되도록 상기 힌지축(100)에 근접하여 상기 제1연결편(210)의 상부에 형성된다.The second connecting piece 220 of the first link 200 is close to the hinge shaft 100 so that the vertical rotation of the first connecting piece 210 is converted to the front and rear rotation of the first connecting piece 210 It is formed on the top.

또, 상기 제1링크(200)에는 일단이 제1연결편(210)의 타단에 연결되는 제2링크(300)가 회전가능하게 연결되되, 상기 제2링크(300)의 타단에는 회전가능하게 돌출되어 상기 제2링크(300)를 차체(10)의 하부에 연결되기 위한 힌지부(400)가 구비된다.In addition, the first link 200 is rotatably connected to the second link 300, one end of which is connected to the other end of the first connecting piece 210, the other end of the second link 300 protrudes rotatably Is provided with a hinge 400 for connecting the second link 300 to the lower portion of the vehicle body (10).

또한, 상기 제1링크(200)의 제2연결편(220)의 단부에는 일단이 고정되며 타단이 상기 볼스터(40)의 측면에 고정되어 대차(20)의 전후방향으로 신축가능한 완충부(500)가 연결된다.In addition, one end is fixed to the end of the second connecting piece 220 of the first link 200 and the other end is fixed to the side of the bolster 40, the cushioning portion 500 that can be stretched in the front and rear direction of the trolley 20. Is connected.

상기 완충부(500)는 유압 댐퍼로 이루어지는 것이 바람직하다.The buffer 500 is preferably made of a hydraulic damper.

한편, 상기 볼스터(40)에 양 측면에는 각각 상기 완충부(500)의 타단을 향하도록 외부로 돌출되어 상기 완충부(500)의 타단을 연결하기 위한 고정부(600)가 형성된다.On the other hand, both sides of the bolster 40 is protruded to the outside to face the other end of the buffer portion 500, respectively, the fixing portion 600 for connecting the other end of the buffer portion 500 is formed.

그리고 상기 볼스터(40)에는 양 측면에 각각 고정되어 상기 힌지축(100)의 단부를 회전가능하게 지지하기 위한 지지부(700)가 각각 형성되되, 상기 지지부(700)는 베어링으로 이루어지는 것이 바람직하다.In addition, the bolsters 40 are fixed to both sides, respectively, and support portions 700 are formed to rotatably support the end portions of the hinge shafts 100, and the support portions 700 are preferably made of bearings.

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

도 3에 도시된 바와 같이 차체(10)가 상하진동 또는 차체의 좌우회전(롤링)을 하게 되면, 제2링크(300)의 타단이 차체(10)와 연결되었기 때문에, 상기 제2링크(300)는 상하방향으로 승강하게 된다.As shown in FIG. 3, when the vehicle body 10 vibrates up and down or left and right (rolling) of the vehicle body, since the other end of the second link 300 is connected to the vehicle body 10, the second link 300 ) Is raised and lowered.

그러므로 제2링크(300)와 연결된 제1링크(200)는 힌지축(100)과 함께 볼스터(40)의 측면에서 회전하게 된다.Therefore, the first link 200 connected to the second link 300 is rotated on the side of the bolster 40 together with the hinge axis 100.

이때, 제1링크(200)의 제1연결편(210)은 힌지축(100)의 단부에 고정되어 일체를 이루기 때문에 힌지축(100)을 중심으로 상하방향으로 회전하게 되지만, 제1링크(200)의 제2연결편(220)은 제1연결편(210)과 직각을 이루며 힌지축(100)에 근접하여 형성되었기 때문에, 제2연결편(220)은 회전방향이 상하방향에서 전후방향으로 전환되어 회전하게 된다.At this time, since the first connecting piece 210 of the first link 200 is fixed to the end of the hinge shaft 100 to form an integrated body, the first connecting piece 210 rotates up and down about the hinge shaft 100, but the first link 200 Since the second connecting piece 220 of) is formed at right angles to the first connecting piece 210 and close to the hinge shaft 100, the second connecting piece 220 is rotated by switching from the up and down direction to the front and back direction. Done.

따라서, 제1링크(200)의 제2연결편(220)과 볼스터(40)의 고정구(600) 사이에 설치된 완충부(500)는 제2연결편(220)의 전후방향회전에 의해 길이를 신축하면서 차체(10)의 상하진동 또는 좌우회전(롤링)을 감쇄시킨다.Therefore, the buffer unit 500 installed between the second connecting piece 220 of the first link 200 and the fastener 600 of the bolster 40 expands and contracts length by the forward and backward rotation of the second connecting piece 220. Reduce the vertical vibration or the left-right rotation (rolling) of the vehicle body (10).
