Description

철도차량용 축상지지 장치{Suspension equipment for rollingstock}Axial support device for rolling stock {Suspension equipment for rollingstock}

본 고안은 철도차량용 2축 차량의 축상지지 장치 구조에 관한 것이며The present invention relates to the structure of the on-axis support device of the two-axis vehicle for railway vehicles

종래의 소형 화차나 소형 입환기관차는 차량 길이가 짧기 때문에 대차(bogie)를 사용할 만한 공간이 부족하여 차체후레임에 축상지지 장치를 직접 취부하여 엑슬박스에 차륜과 차축이 조립되는 구조로 되어 있어 대차를 사용할 때보다 축간거리{ 엑슬과 엑슬 사이의 거리}가 길게 되어 변위각{ 차량이 곡선 선로에 있을 때 곡선 중심과 축간 거리간에 이루는 각도}이 크게 되어 진다는 단점이 있으며Conventional small wagons or small-sized locomotives have a short vehicle length, so there is not enough space to use bogies, and the wheel and axles are assembled on the axle box by directly mounting the axial support on the frame of the body. Its disadvantage is that the distance between the axle and the axle is longer than when used, resulting in a larger displacement angle (the angle between the center of the curve and the distance between the axes when the vehicle is on a curved track).

종래의 패데스탈 형(pedestal type) 의 축상지지 장치 구조는 도 2와 같이 차체후레임(1)에 취부되어 있는 패데스탈(21)의 사이에 엑슬박스(5)가 2mm 정도의 틈새(37)를 가지고 엑슬스프링(6) 의 상하방향의 진동 변위에 따라 습동(sliding) 하는 구조로 되어 있어 2축 차량의 큰 변위각을 흡수 할 수 없는 구조이기 때문에 차륜 공격각{ 차량이 곡선 선로에 있을 때 차륜 후렌지와 선로가 이루는 각도}이 크게 되어 차륜에 직립마모 현상이 발생하게 되고 주행 성능도 나쁘게 된다는 결점을 가지고 있다.In the conventional pedestal type axial support device structure, as shown in FIG. 2, the axle box 5 has a gap 37 between the pedestals 21 mounted on the vehicle frame 1 as much as 2 mm. Wheel sliding angle in accordance with the up and down vibration displacement of the axle spring 6, so that the large displacement angle of the two-axis vehicle cannot be absorbed. The angle between the flange and the track is increased, resulting in an upright wear phenomenon on the wheels and poor driving performance.

2축 차량이 가지고 있는 곡선 주행 시 큰 변위각 문제로 인해 차륜의 직립마모 현상 발생과 주행성능 저하를 개선하기 위하여 엑슬박스에 조립되어 있는 차륜과 차축이 엑슬스프링과 고무스프링에 의하여 상하,전후,좌우 모든 방향으로 탄성 연결되게 하고The wheels and axles of the axle box are mounted on the axle box by the axle spring and the rubber spring to improve the upright wear of the wheel and the deterioration of the driving performance due to the large displacement angle problem in the driving of the two-axis vehicle. Elastic connection in all directions

엑슬박스를 축상지지대에 탄성 연결함에 있어 고무스프링 링크를 사용하여 고무스프링을 2중으로 설치함으로써 고무스프링의 탄성을 이용하여 2축 차량의 큰 변위각을 충분히 흡수 할 수 있는 축상지지 장치를 제공하기 위한 것이다.In the elastic connection of the axle box to the axial support, the rubber spring link is used to install the rubber spring twice so that the axial support device can sufficiently absorb the large displacement angle of the two-axis vehicle by using the elasticity of the rubber spring. will be.
