    • Problem to be Solved
      There is provided a self-steering bogie having a simple structure having improved running stability and curving performance.
      Solution
      A tread 5 of a wheel 3 in contact with a rail 4 is inclined so that a radius of rotation is gradually increased outward with reference to the rail, and is inclined in a direction opposite to a conventional tread. Thus, gravitational restoring forces F1 and F2 generated by wheel loads P1 and P2 are oriented outward with reference to the rail. Thus, when displacement in a yaw direction occurs, the gravitational restoring forces F1 and F2 generate a moment M in a direction of eliminating the displacement in the yaw direction with respect to a center O1 of a bogie. The moment M is a self-steering moment that causes the bogie to follow the rail 4.
    • 要解决的问题提供了一种具有改进的运行稳定性和弯曲性能的简单结构的自动导向转向架。 解决方案与轨道4接触的车轮3的胎面5倾斜,使得相对于轨道向外逐渐增加旋转半径,并且沿与传统胎面相反的方向倾斜。 因此,由车轮载荷P1和P2产生的重力恢复力F1和F2相对于轨道向外取向。 因此,当发生偏航方向的位移时,重力恢复力F1和F2在相对于转向架的中心O1消除偏航方向上的位移的方向上产生力矩M. 当时M是一个自转转向时刻,导致转向架跟随轨道4。
