Description

곡선부 고속주행용 철도차량 회전,경사바닥{Rounded Section Car-Floor for speed up on curved rail}Rounded Section Car-Floor for speed up on curved rail}

본 발명은 곡선부 고속주행용 철도차량 회전,경사바닥에 관한 것으로, 차체의 바닥판을 회동가능하게 형성하여 차체의 경사장치를 형성하지 않아도 차체의 횡가속도를 감쇄시킬 수 있어 적은 제작비용과 적은 유지보수 비용으로도 승차감을 향상시키고 곡선부에서 차량의 속도를 높일 수 있는 곡선부 고속주행용 철도차량 회전,경사바닥에 관한 것이다.The present invention relates to the rotation and inclined floor of a railway vehicle for driving at high speeds of curved portions, and is capable of attenuating the lateral acceleration of a vehicle body without forming an inclined device of the vehicle body by forming the base plate of the vehicle body so as to be rotatable. The present invention relates to the rotation and inclined floor of a curved high-speed railroad car that can improve ride comfort even at a maintenance cost and speed up the vehicle at the curved portion.

일반적으로 차체경사장치는 베어링 가이드식과 링크식으로 나누어지며 곡선부 주행시 차체를 곡선의 안쪽으로 기울어지게 하는 기술로써 곡선부를 주행함으로써 발생하는 원심가속도(αcen=Ｖ2/Ｒ)의 횡방향성분(αcenCOS(α+γ))을 중력가속도(ｇ)의 횡방향 성분(ｇ sin (α+γ))으로 감쇄시켜 결과적으로 승객이 느끼는 횡가속도를 저감시키는 기술이다.In general, the car body tilt system is transverse component of the centrifugal acceleration (α cen = V 2 / R ) caused by driving parts of the curve as the technique for tilting the curved portion when driving the vehicle body is divided into bearing guide expression link formula to the inside of the curve ( α cen COS (α + γ) attenuates the lateral component of the gravitational acceleration (g) (g sin (α + γ)) to reduce the lateral acceleration that the passenger feels.

철도차량에 이와같은 차체경사장치(틸팅)기술을 적용하면 승차감의 향상뿐만 아니라 곡선부 통과속도를 증가시킬 수 있게 되므로 운행시간이 단축되며, 곡선부 통과시의 가 감속 빈도도 줄어들어 그 만큼의 에너지 소비도 줄일 수 있게된다.Applying this body tilting device technology to railway vehicles can improve driving comfort as well as increase the passage speed of the curved section, reducing the operating time and reducing the frequency of acceleration and deceleration during the curved section. Consumption can also be reduced.

또한 차체경사장치는 곡선부에서 약30% 정도의 속도향상을 가능하게 해준다.In addition, the body slope allows speed improvement of about 30% in the curve.

이와같은 곡선부의 속도제한은 궤도여건이나 차량의 성능에 따른 제한보다 승차감의 저하를 방지하기 위해 규정지어지는데 즉 곡선부 주행시 승객이 느끼는 횡가속도가 일정값(국내의 경우는 0.08g)을 초과하지 않도록 제한되어지며 틸팅의원리에 따라 틸팅차량은 노선에 곡선부가 많을 수록 성능을 발휘하고 직선부에서는 작동을 하지 않는다.The speed limit of the curved section is defined to prevent the deterioration of ride comfort rather than the limit of track conditions or the performance of the vehicle. That is, the lateral acceleration felt by the passenger when driving the curved section does not exceed a certain value (0.08g in domestic). According to the principle of tilting, the tilting vehicle performs better as there are more curved parts on the route, and it does not work on the straight part.

상기와 같은 종래의 차체경사장치의 전형적인 일예가 도1에 도시되어 있다.A typical example of such a conventional body tilt device is shown in FIG.

그러나 상기와 같은 차체경사장치는 곡선부에서 차체를 기울여서 승객이 받는 횡가속도를 중력가속도로 감쇄시켜 승차감을 향상시키고 차량의 속도를 향상시킬 수 있으나 차체 틸팅시 대차와 판토그라프의 상호 조화롭게 작동하는 것이 중요하여 차체경사장치는 틸팅대차와 틸팅판토그라프가 필요하나 조화롭게 작동하는 기술이 고도의 기술이고 고가의 제작비용이 소요되는 문제점이 있었다.However, the above-mentioned body slant can reduce the lateral acceleration received by the passengers by the gravity acceleration by tilting the body at the curved portion to improve the ride comfort and improve the speed of the vehicle.However, when the body tilts, the bogie and the pantograph work in harmony. Importantly, the car body tilting device requires a tilting bogie and a tilting pantograph, but there is a problem in that a technique that works in harmony is a high technology and requires expensive manufacturing costs.

이에 본 발명은 상기와 같은 종래기술의 제반 문제점을 감안하여 안출한 것으로 차체의 바닥판을 회동가능하게 형성하여 틸팅대차와 틸팅판토그라프를 형성하지 않아도 차체의 횡가속도를 감쇄시킬 수 있어 적은 제작비용과 적은 유지보수 비용으로도 승차감을 향상시키고 곡선부에서 차량의 속도를 높일 수 있는 곡선부 고속주행용 철도차량 회전,경사바닥를 제공하는데 그 목적이 있다.Accordingly, the present invention has been devised in view of the above-mentioned problems of the prior art, and the lower plate of the vehicle body can be rotatably formed to reduce the lateral acceleration of the vehicle body without forming the tilting cart and the tilting pantograph.
