摘要
A semi-active steering bogie for railway vehicle with a variable damper is provided to keep the damping coefficient of the variable damper high while the railway vehicle travels on a straight track and low while traveling on a curved track, thereby improving traveling stability. A semi-active steering bogie for railway vehicle comprises an axle box(104) installed on both ends of a wheel axle, and a variable damper(105) combined in a bogie frame(101) to support the axle box. The variable damper is installed horizontally to the wheel axle and controlled in damping coefficient by a sensor unit and a control unit according to whether the railway vehicle travels on a straight track or a curved track.
