무궤도 열차의 객차 4륜조향장치{4 wheel steering apparatus for passenger car of trackless tram}4 wheel steering apparatus for passenger car of trackless tram}

본 발명은 무궤도 열차의 객차 4륜조향장치에 관한 것으로, 특히 견인차와 객차가 동일한 트랙을 따라 주행할 수 있도록 한 무궤도 열차의 객차 4륜조향장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carriage four-wheel steering apparatus for a trolley train, and more particularly, to a carriage four-wheel steering apparatus for a trolley train allowing a tow truck and a passenger car to travel along the same track.

예로부터 전륜만이 조향되는 전륜조향차량, 즉 2륜조향차량이 널리 사용되어 왔으나, 근래에는 전륜과 후륜이 동시에 조향되는 4륜조향차량이 개발되고 있다.In the past, a front wheel steering vehicle in which only front wheels are steered, that is, a two-wheel steering vehicle, has been widely used. In recent years, a four-wheel steering vehicle in which both front and rear wheels are steered at the same time has been developed.

이러한 4륜조향차량은 저속에서 차량을 매우 용이하게 조종할 수 있으며, 고속 주행에서도 차량의 안정성(stability), 핸들링(handling) 및 조정성(control)을 향상시켜주며 특히 미끄러짐에 의한 차량 뒤쪽의 흔들림을 줄여서 안정된 주행을 가능하게 하는 장점이 있다.These four-wheel steering vehicles can easily steer the vehicle at low speeds and improve the stability, handling and control of the vehicle even at high speeds. There is an advantage to enable a stable running by reducing the.

한편, 놀이공원 등에서 관람객의 운송을 위해 운행되는 소위 로드 트레인(Road Train)과 같은 무궤도 열차의 경우 엔진이 탑재된 동력 견인차와 이 견인차에 복수 량의 무동력 객차를 연결하여 운행하고 있다.Meanwhile, a trolleybus such as a so-called road train, which is operated for transportation of visitors in an amusement park, is connected to a powered tow truck equipped with an engine and a plurality of non-powered cars to the tow truck.

그러나 종래의 무궤도 열차는 견인차로서 전륜만 조향되는 2륜조향차량을 사 용하고, 객차는 4륜 모두 조향되지 않는 차량을 사용하고 있으므로 객차가 견인차의 궤도를 정확히 추종하지 못하고 그 궤도를 벗어나게 되어 주변의 시설물이나 관람객과 접촉 또는 추돌하는 등의 안전사고를 초래하는 문제점이 있다.However, the conventional trolleybus uses a two-wheel steering vehicle in which only the front wheels are steered as a tow truck, and the passenger car uses a vehicle that is not steered on all four wheels. There is a problem that causes safety accidents such as contact or colliding with the facilities or visitors.

따라서 종래의 무궤도 열차는 직선노선으로 운행하거나 완만한 곡선노선을 포함하는 노선으로 운행하고 있는 실정이며, 이에 따라 무궤도 열차의 운행에 제약이 따르게 되고, 관람객들에게는 흥미를 반감시키게 되는 문제점이 있다.Accordingly, the conventional trolleybus trains operate in a straight line or in a route including a smooth curved line, and thus there is a problem in that the trolley train is restricted, and interests are halved.

따라서 본 발명의 목적은 무궤도 열차의 견인차와 객차를 모두 4륜조향차량으로 구성하고, 견인차의 조향에 연동하여 객차가 조향되면서 객차가 견인차의 궤도를 벗어나지 않고 정확하게 추종할 수 있도록 하여 안전사고를 최소화할 수 있도록 한 무궤도 열차의 객차 4륜조향장치를 제공하려는 것이다.Accordingly, an object of the present invention is to configure a tow truck and a carriage of a trolleybus as a four-wheel steering vehicle, and minimize the safety accident by allowing the carriage to accurately follow without leaving the track of the tow vehicle while the carriage is steered in conjunction with the steering of the tow vehicle. It is to provide a four-wheeled steering car for a trolleybus.

이하, 본 발명에 의한 무궤도 열차의 객차 4륜조향장치의 운행과정을 설명한다.Hereinafter, the operation process of the carriage 4 wheel steering apparatus of the trolleybus according to the present invention.

도 1 및 도 3에 도시한 바와 같이, 견인차(T)가 직선노선을 주행할 경우에는 견인차(T)의 후단 히치부(15)와 최선행 객차(P)의 선단 히치부(25)를 굴절 가능하게 연결하는 견인차 객차간 견인로드(27)와, 최선행 객차(P)의 후단 히치부(26)와 후행 객차(P)의 선단 히치부(25)를 굴절 가능하게 연결하는 객차간 견인로드(28)가 견인차(T) 및 객차(P)의 중심선에 일치하는 상태로 되고, 이에 따라 견인차 객차간 견인로드(27)의 연동아암(90)과 벨 크랭크(50)의 우측 아암(52)을 굴절 가능하게 연결하는 연동로드(120)와 객차간 견인로드(28)의 연동아암(100)과 벨 크랭크(50)의 우측 아암(52)을 굴절 가능하게 연결하는 연동로드(120)가 견인차(T)와 객차(P)의 중심선과 평행을 이루는 상태로 되며, 벨 크랭크(50)는 그 좌우 아암(51,51)이 견인차(T)와 객차(P)의 중심선에 직각을 이루는 상태로 유지되어 객차(P)의 전,후 륜(22,24)은 견인차(T)의 전,후륜(12,14)과 평행한 상태에서 직선노선을 따라 주행하게 된다.As shown in FIGS. 1 and 3, when the tow truck T travels on a straight line, the rear hitch 15 of the tow T and the front hitch 25 of the best passenger car P are refracted. Traction rod 27 between the tow carriage carriage which connects possibly, and the trailing hitch portion 26 of the best carriage P and the end hitch portion 25 of the trailing carriage P can be deflected. 28 is in a state coinciding with the center lines of the tow truck T and the carriage P, and accordingly, the linkage arm 90 of the tow carriage carriage 27 and the right arm 52 of the bell crank 50. Interlocking rod 120 for refraction connecting the linkage arm 100 and the right arm 52 of the bell crank 50 between the interlocking rod 120 and the towing rod 28 between the carriages is a tow vehicle It is in a state parallel to the center line of the (T) and the carriage (P), the bell crank 50 is an image in which the left and right arms (51, 51) are perpendicular to the center line of the tow (T) and the carriage (P) Is held in the carriage before and after (P), wheel 22 and 24 is to travel along a straight line in parallel with the former state, the rear wheels 12, 14 of the tow (T).

도 2 및 도 4에 도시한 바와 같이, 견인차(T)가 곡선노선을 좌회전할 경우에는 견인차(T)의 후단 히치부(15)와 최선행 객차(P)의 선단 히치부(25)를 굴절 가능하게 연결하는 견인차 객차간 견인로드(27)와 이에 고정 설치된 연동아암(90)이 히치핀(27a)을 중심으로는 시계방향 히치핀(27b)을 중심으로는 반시계방향으로 굴절되어 연동아암(90)에 굴절 가능하게 연결된 연동로드(120)가 주행 방향으로 당겨지게 되며, 이에 따라 연동로드(120)의 후단에 그 우측 아암(52)이 굴절 가능하게 연결된 전륜측 벨 크랭크(50)가 반시계방향으로 회전하게 되며, 이 벨 크랭크(50)의 후향 아암(53)에 조향로드(70)에 의해 굴절 가능하게 연결된 조향아암(30)이 반시계방향으로 회전하게 되고, 이 조향아암(30)에 고정 설치된 허브축(31)이 반시계방향으로 회전하게 되어 이 허브축(31)에 회전 가능하게 설치된 최선행 객차(P)의 객차 전륜(22)이 곡선노선의 궤도를 따라 조향된다.As shown in FIG. 2 and FIG. 4, when the tow vehicle T turns the curved line to the left, the rear hitch 15 of the tow vehicle T and the tip hitch 25 of the best passenger car P are refracted. Traction rod 27 between the wagon and the intercommunication arm 90 fixedly connected to the tow truck carriage that can be connected is refracted counterclockwise about the hitch pin 27b about the hitch pin 27a and the linkage arm. The linkage rod 120 that is deflectably connected to the 90 is pulled in the driving direction, and thus, the front wheel side crank 50 to which the right arm 52 is deflectably connected to the rear end of the linkage rod 120 is connected. It rotates in a counterclockwise direction, and the steering arm 30, which is deflectably connected by the steering rod 70 to the rear arm 53 of the bell crank 50, rotates in the counterclockwise direction. The hub shaft 31 fixed to the shaft 30 is rotated counterclockwise so that the hub shaft 31 is rotated counterclockwise. Carriage wheels 22 of the carriages best line (P) to be installed is steered along the curved trajectory of the route.

또한 전륜측 벨 크랭크(50)의 좌측 아암(51)에 그 우측 아암(62)이 전후륜 연동링크(110)에 의해 굴절 가능하게 연결된 후륜측 벨 크랭크(60)는 시계방향으로 회전하게 되고, 이에 따라 이 벨 크랭크(60)의 후향 아암(63)에 조향로드(80)에 의해 굴절 가능하게 연결된 조향아암(40)이 시계방향으로 회전하게 되고, 이 조향아암(40)에 고정 설치된 허브축(41)이 시계방향으로 회전하게 되어 이 허브축(41)에 회전 가능하게 설치된 최선행 객차(P)의 객차 후륜(24)이 곡선노선의 궤도를 따라 조향된다.In addition, the rear wheel crank 60 is connected to the left arm 51 of the front wheel side crank 50 so that the right arm 62 can be deflected by the front and rear wheel linkage 110, and rotates clockwise. As a result, the steering arm 40 which is refractorably connected to the rear arm 63 of the bell crank 60 by the steering rod 80 is rotated in the clockwise direction, and the hub shaft fixed to the steering arm 40 is fixed. (41) is rotated clockwise so that the carriage rear wheels 24 of the best passenger cars P rotatably provided on the hub shaft 41 are steered along the trajectory of the curved line.

또한 최선행 객차(P)의 후단 히치부(26)에 그 선단측 히치부(25)가 객차간 견인로드(28)에 의해 굴절 가능하게 연결된 후향 객차(P)들은 연동로드(130), 전륜측 벨 크랭크(50), 조향로드(70), 조향아암(30), 전후륜 연동링크(110), 후륜측 벨 크랭크(60), 조향로드(80), 조향아암(40)의 작용으로 상술한 최선행 객차(P)와 마찬가지로 그 객차 전,후륜(22,24)이 곡선노선의 궤도를 따라 조향된다.In addition, the rear carriage (P) is connected to the rear hitch (26) of the best passenger carriage (P) so that the front side hitch 25 is refracted by the towing rod 28 between the carriages interlocking rod (130), front wheel By the action of the side bell crank 50, steering rod 70, steering arm 30, front and rear wheel linkage link 110, rear wheel side crank 60, steering rod 80, steering arm 40 As with the best passenger carriage P, the front and rear wheels 22 and 24 of the carriage are steered along the trajectory of the curved line.

따라서 모든 객차(P)들의 전,후륜(22,24)은 견인차(T)의 주행에 따른 곡선노선의 궤도를 따라 조향되므로 모든 객차(P)들이 견인차의 궤도를 벗어나지 않고 정확하게 추종하게 된다.Therefore, since the front and rear wheels 22 and 24 of all the passenger cars P are steered along the trajectory of the curved line according to the driving of the tow vehicle T, all the passenger cars P are accurately followed without leaving the track of the tow vehicle.
