Description

철도차량의 양력발생장치{Lift device for railway vehicle}Lift device for railway vehicle {Lift device for railway vehicle}

본 발명은 철도차량의 양력발생장치에 관한 것으로서, 더욱 상세하게는 레일(Rail) 위를 고속으로 주행하는 철도차량의 지붕 윗면에 비행기의 날개형상으로 이루어진 양력발생수단을 설치하여 차체에 의해 선로(線路)에 가해지는 하중을 경감시켜 차량의 견인효율을 증대시키고 선로의 파손을 방지할 수 있으며, 제동시에는 공기저항판으로 작동하여 제동거리를 감소시킬 수 있도록 한 철도차량의 양력발생장치에 관한 것이다.The present invention relates to a lifting device of a railway vehicle, and more particularly, by installing a lifting force generating unit formed in the shape of a wing of an airplane on the upper surface of a roof of a railway vehicle traveling on a rail at a high speed by a track (by a vehicle body). It is possible to reduce the load on the line to increase the traction efficiency of the vehicle and to prevent the breakage of the track.In the case of braking, it is possible to reduce the braking distance by acting as an air resistance plate. will be.

통상적으로, 레일 위를 고속으로 주행하는 철도차량은 전방에 배치되는 동력차에 의해 구동력을 발생시키고, 이 동력차의 후방에 여러 객차가 연결되어 한번에 많은 승객을 실어 장거리를 운행할 수 있다.In general, a railroad car traveling at a high speed on a rail generates a driving force by a power vehicle disposed in front, and a plurality of passenger cars are connected to the rear of the power vehicle so that a large number of passengers can be driven at a long distance.

이러한 철도차량은 고속화 및 안정성을 주요 과제로 하여 많은 발전을 이루어 왔으며, 최근에 이르러 자기부상열차(Magnetic Levitation Train)나 고속열차 (High Speed Train) 등과 같이 주행속도가 높은 철도차량이 개발되고 있다.Such railway vehicles have been developed with high speed and stability as main tasks, and recently, high-speed railway vehicles such as magnetic levitation trains and high speed trains have been developed.

그런데, 철도차량은 공기의 역학적 특성에 따라 공기저항의 차이가 두드러지게 나타날 수 있으며, 특히 동력차의 전두부(前頭部)의 형상에 따라 공기저항을 감소시켜 견인효율을 향상시킬 수 있게 된다.By the way, the difference in the air resistance may be remarkable depending on the mechanical characteristics of the air vehicle, and in particular, it is possible to improve the traction efficiency by reducing the air resistance according to the shape of the front head of the power vehicle.

실질적으로, 철도차량에 있어서의 전두부 구조에 의한 공기저항은 전체적으로 대략 10% 정도를 차지하게 되며, 그 이외의 공기저항은 객차의 측면에 의한 것이 대부분이지만 객차의 외관구조 및 그 형태는 거의 유사하기 때문에 객차 구조의 설계변경에 의해 공기저항을 개선하기는 매우 어려운 실정이다.In practical terms, the air resistance due to the frontal head structure of railroad cars occupies about 10% of the total, and the other air resistance is mostly due to the side of the passenger car, but the exterior structure and shape of the passenger car are almost similar. Therefore, it is very difficult to improve air resistance by changing the design of the carriage structure.

따라서, 실제 공기저항의 개선을 위해서는 동력차의 전두부 구조를 변경하여 공기저항에 대한 특성을 향상시키는 것이 더 효율적이라 할 수 있다.Therefore, in order to improve the actual air resistance, it is more efficient to change the front head structure of the power vehicle to improve the air resistance characteristics.

본 발명은 상술한 바와 같은 점을 감안하여 이루어진 것으로서, 본 발명의 목적은, 레일 위를 고속으로 주행하는 철도차량의 지붕 윗면에 비행기의 날개형상으로 이루어진 양력발생수단을 설치함으로써, 고속 주행시의 차체에 의해 선로에 가해지는 하중을 경감시켜 차량의 견인효율을 증대시키고 선로의 파손을 방지할 수 있는 철도차량의 양력발생장치를 제공함에 있다.The present invention has been made in view of the above-described point, and an object of the present invention is to provide a vehicle body at high speed by providing a lift generating means formed in the shape of a wing of an airplane on the upper surface of a roof of a railway vehicle traveling on a rail at high speed. It is to provide a lifting force generating device of a railway vehicle that can reduce the load applied to the track by increasing the traction efficiency of the vehicle and prevent the damage of the track.

본 발명의 다른 목적은, 고속 주행하는 철도차량의 제동시에 상기 양력발생수단을 회동시킴으로써, 공기저항판으로 작동하여 제동거리를 감소시킬 수 있도록 한 철도차량의 양력발생장치를 제공함에 있다.Another object of the present invention is to provide a lifting force generating device for a railway vehicle, which is capable of reducing the braking distance by operating the air resistance plate by rotating the lifting force generating means when braking the railway vehicle traveling at high speed.

도 1 내지 도 4는 본 발명에 따른 철도차량의 양력발생장치를 설명하기 위한 도면으로서, 먼저 도 1 및 도 2에 나타낸 바와 같이, 철도차량(10)을 구성하는 동력차(11)의 전두부(12)에는 기관사가 전방을 주시하기 위한 전면유리창(13)이 장착되어 있고, 그 후방으로 연결되는 각 객차(14)에는 그 길이방향을 따라 출입문(15) 및 창문(16)이 일정 간격으로 배치되어 있다.1 to 4 are diagrams for explaining a lift generating device of a railway vehicle according to the present invention. First, as shown in FIGS. 1 and 2, the front head part 12 of the power vehicle 11 constituting the railway vehicle 10 is shown. ) Is equipped with a front windshield 13 for the engineer to look forward, and each carriage 14 connected to the rear is provided with a door 15 and a window 16 at regular intervals along its longitudinal direction. have.

또한, 상기 철도차량(10)의 지붕(17) 윗면에는 비행기의 날개형상으로 이루어진 양력발생수단이 마련되어 있다.In addition, a lifting force generating means formed in the shape of a wing of an airplane is provided on the upper surface of the roof 17 of the railroad vehicle 10.

이 양력발생수단은, 전방부(18a)로부터 후방부(18b)로 향해 점차 얇아지는 날개체(18)를 구비하고 있으며, 이 날개체(18)의 저면에 실린더부재(19A,19B)가 설치되어 도 3a 및 도 3b에서와 같이 차량(10)의 주행시에는 날개체(18)를 수평상태로 유지하고, 제동시에는 날개체(18)의 전방부(18a)를 상측으로 밀어올려 공기저항판으로 작동할 수 있도록 되어 있다.This lifting force generating means has a wing body 18 gradually thinning from the front portion 18a to the rear portion 18b, and cylinder members 19A and 19B are provided on the bottom surface of the wing body 18. 3A and 3B, the wing body 18 is kept in a horizontal state when the vehicle 10 is traveling, and the braking plate is pushed upward by pushing the front portion 18a of the wing body 18 upward when braking. It is designed to work.

그리고, 상기 실린더부재(19A,19B)는 주지하는 바와 같이 구동모터(도시생략)에 의해 작동시킬 수 있도록 되어 있으며, 도 2에서와 같이 실린더부재(19A, 19B)는 날개체(18)의 구조상, 사방 모서리에 각각 설치하는 것이 바람직하다.In addition, the cylinder members 19A and 19B can be operated by a driving motor (not shown), as is well known, and the cylinder members 19A and 19B are structured of the wing body 18 as shown in FIG. It is preferable to install at the four corners, respectively.

또한, 상기 양력발생수단은, 도 1 및 도 2에서와 같이 차량(10)의 지붕(17) 윗면 전후부에 날개체(18)의 전방부(18a) 및 후방부(18b)의 위치를 서로 반대로 하여 각각 1쌍씩 설치되어 있으며, 차량(10)의 지붕(17) 내면에 마련되어 있는 수납부(20)로 출몰이 가능하도록 구성되어 있다.In addition, the lift generating means, as shown in Figs. 1 and 2, the positions of the front portion 18a and the rear portion 18b of the wing body 18 on the front and back of the upper surface of the roof 17 of the vehicle 10 are mutually different. On the contrary, each pair is provided one by one, and it is comprised so that it may be shown in and received by the accommodating part 20 provided in the roof 17 inner surface of the vehicle 10.

한편, 도 4는 본 발명의 다른 예를 설명하기 위한 도면으로서, 상기 양력발생수단을 구성하는 날개체(18)를 차량(10)의 지붕(17) 윗면 양측에 하나씩 만을 설치하고, 차량(10)의 전, 후 주행방향에 따라 도시하지 않은 회전구동수단에 의해 180°회전되도록 구성할 수 있다.On the other hand, Figure 4 is a view for explaining another example of the present invention, the vehicle body 10 is provided with only one wing body 18 constituting the lifting force generating means on both sides of the upper surface of the roof 17 of the vehicle 10, It can be configured to rotate 180 ° by a rotation driving means (not shown) according to the before and after driving direction.

또한, 상기 날개체(18)의 저면에는 전술한 도 3a 및 도 3b에서와 마찬가지로 차량(10)의 주행시에는 상기 양력발생수단을 구성하는 날개체(18)를 수평상태로 유지하고, 제동시에는 날개체(18)의 전방부(18a)를 상측으로 밀어올려 공기저항판으로 작동시킬 수 있게 된다.In addition, on the bottom of the wing body 18, as in FIGS. 3A and 3B, the wing body 18 constituting the lift generating means is kept in a horizontal state when the vehicle 10 travels, and at the time of braking. The front portion 18a of the wing body 18 can be pushed upward to operate as an air resistance plate.

상술한 바와 같이 구성된 본 발명은, 철도차량(10)의 동력차(11)가 도 1 및 도 2에 도시된 화살표 방향으로 고속 주행하는 경우, 외부공기가 동력차(11) 및 객차(14)의 지붕(17) 윗면에 장착되어 있는 양력발생수단에 작용하게 된다.According to the present invention configured as described above, when the power vehicle 11 of the railroad vehicle 10 travels at a high speed in the direction of the arrow shown in FIGS. 1 and 2, the outside air has a roof of the power vehicle 11 and the carriage 14. (17) It acts on the lift generating means mounted on the upper surface.

따라서, 도 3a에서와 같이 수평방향으로 유지된 날개체(18)를 향해 화살표 방향으로 불어오는 공기저항에 의해 날개체(18)에는 양력이 발생하게 되고, 주지의 베르누이 정리(Bernoull's theorem), 즉 비행기의 이륙원리에 의해 차체는 선로로부터 부상(浮上)하려고 하는 힘을 받게 되므로, 차량(10)의 자체무게로 인하여 선로에 가해지는 하중을 경감시킬 수 있게 된다.Accordingly, lift force is generated in the wing body 18 by air resistance blowing in the direction of the arrow toward the wing body 18 held in the horizontal direction as shown in FIG. 3A, and thus known Bernoulli's theorem. Due to the take-off principle of the plane, the body is subjected to the force to rise from the track, thereby reducing the load on the track due to the weight of the vehicle 10 itself.

이 때, 상기 날개체(18)의 후방에 반대방향으로 설치되어 있는 날개체(18)는 전혀 공기저항의 영향을 받지 않게 된다.At this time, the wing body 18 provided in the opposite direction to the rear of the wing body 18 is not affected by air resistance at all.

또한, 상기 차량(10)이 반대방향으로 주행하는 경우에는, 전술한 바와 반대로 날개체(18)가 양력을 받게 되는 것이며, 차량(10)의 주행방향에 따라 공기저항을 받지 않는 어느 한쪽의 날개체(18)는 지붕(17) 내부에 마련되어 있는 각각의 수납부(20)로 하강이동시켜 수납시킬 수 있도록 되어 있다.In addition, when the vehicle 10 travels in the opposite direction, the blade body 18 is lifted in contrary to the above-mentioned, and any one of the blades does not receive air resistance according to the driving direction of the vehicle 10. The object 18 can be moved down to each storage part 20 provided in the roof 17, and can be accommodated.

그리고, 차량(10)의 제동시에는, 도 3b에 나타낸 바와 같이 날개체(18)의 전방부(18a)에 설치되어 있는 실린더부재(19A)를 상측으로 작동시켜 줌으로써, 날개체(18)의 전방부(18a)가 상향 이동하여 공기저항판으로 작용하게 되어 제동력에 영향을 주게 되므로, 제동거리를 감소시킬 수 있게 된다.At the time of braking of the vehicle 10, as shown in FIG. 3B, the cylinder member 19A provided at the front portion 18a of the wing 18 is operated upward, thereby operating the wing 18. Since the front portion 18a moves upward to act as an air resistance plate to affect the braking force, the braking distance can be reduced.

한편, 도 4에서와 같이 차량(10)의 지붕(17) 양측에 날개체(18)가 하나씩 설치되어 있는 경우에는, 차량(10)의 전, 후 주행방향에 따라 날개체(18)를 180°회전되도록 함으로써, 전술한 실시예와 마찬가지의 작용을 수행할 수 있게 된다.On the other hand, as shown in FIG. 4, when the wing bodies 18 are provided on both sides of the roof 17 of the vehicle 10 one by one, the wing bodies 18 are 180 in accordance with the front and rear travel directions of the vehicle 10. By rotating it, it is possible to perform the same operation as in the above-described embodiment.

상술한 실시예는 본 발명의 가장 바람직한 예에 대하여 설명한 것이지만, 상기 실시예에만 한정되는 것은 아니며, 본 발명의 기술사상을 벗어나지 않는 범위 내에서 다양한 변형이 가능하다는 것은 당업자에게 있어서 명백한 것이다.Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention.

이상에서와 같이, 본 발명에 따른 철도차량의 양력발생장치에 의하면, 레일 위를 고속으로 주행하는 철도차량의 지붕 윗면에 비행기의 날개형상으로 이루어진 양력발생수단을 설치함으로써, 고속 주행시의 차체에 의해 선로에 가해지는 하중을 경감시켜 차량의 견인효율을 증대시키고 선로의 파손을 방지할 수 있으며, 더욱 주행 안정성을 확보할 수 있게 된다.As described above, according to the lift generating device of the railway vehicle according to the present invention, by providing a lift generating means formed in the shape of the wing of the plane on the upper surface of the roof of the railway vehicle traveling on the rail at high speed, By reducing the load on the track, it is possible to increase the traction efficiency of the vehicle, to prevent the damage of the track, and to secure driving stability more.

또한, 고속 주행하는 철도차량의 제동시에는 상기 양력발생수단을 회동시켜 공기저항판으로 작동되도록 함으로써, 제동거리를 감소시킬 수 있게 되므로 안전사고의 유발을 사전에 방지할 수 있는 효과가 있다.In addition, the braking distance can be reduced by rotating the lift generating means to operate the air resistance plate when braking the railway vehicle traveling at high speed, thereby preventing the occurrence of a safety accident in advance.
