To provide a constitution of a bolster-less bogie which is light-weight, short in height and less expensive in production, capable of travelling on a sharply curved track with a short curvature radius.SOLUTION: A bolster-less bogie provided with a bogie frame and lower and upper surface plates comprises a pair of air springs which is arranged between the bogie frame and a vehicle body and so fitted to the bogie frame that a relative displacement in the vehicle length direction from the body is given as well, a sliding plate installed on the lower part of the body, a side bearer installed on the upper surface plate and in the vehicle length direction slidably contacting with the underside of the sliding plate and an anchor member restraining a relative displacement of the upper surface plate in the vehicle length direction from the lower surface plate.SELECTED DRAWING: Figure 1
【課題】台車を軽量かつ低背にでき且つ製作コストも低減できるボルスタレス台車において、曲率半径の小さい急曲線を走行することができる構成を提供する。【解決手段】ボルスタレス台車は、台車枠と、下面板及び上面板を有し、前記台車枠と車体との間に配置され、前記台車枠に取り付けられると共に前記車体に対して車両長手方向に相対変位自在に設けられる一対の空気バネと、前記車体の下部に取り付けられる擦り板と、前記上面板に取り付けられ、前記擦り板の下面に対して車両長手方向に摺動可能に接触する側受と、前記上面板と前記下面板との間の車両長手方向の相対変位を拘束するアンカー部材と、を備える。【選択図】図1
