Description of the Related Art Most of the currently used bogies for railway vehicles employ a biaxial bogie, and although there are many types of each type and structure of each part, the basic structure and constitution of the bogie are almost the same. It is the same and is generally composed of a bogie frame, a swing pillow device, a spring device, a bearing axle box, an axle box support device, a wheel axle, a basic brake device, and the like. As shown in FIGS. 10A and 10B, the basic structure of the bogie includes a bogie frame 1, an axle 2, wheels 3, an axle box 4, a primary spring 5 and a secondary spring 6. Further, a conical ring having a tread slope θ is used for the wheel 3 in order to facilitate passage through a curved road.

くなる。この現象は、蛇行動と呼ばれており、また蛇行
動の発生する走行速度を安定限界速度と呼ぶ。For this reason, the tread radius varies depending on the position of the tread contacting the rail, and the wheels are asymmetric due to wear. In addition, the two rails are subject to geometrical errors from the viewpoint of facilities and maintenance. Because of these,
The center of the wheel on the left and right rolls at a position deviated from the center of the track. In addition, the resistance received during rolling is different for the left and right wheels, causing slippage on the tread, and one wheel advances more or slower than the other wheel, so a running angle of delay or advance occurs on the wheel and the maximum value After reaching the maximum value, the maximum value of the traveling angle is advanced or delayed for one cycle (Fig. 1).
1) (shown by the meandering wavelength L). When this cycle is repeated, the transfer locus around the wheel axle draws a curve having a constant wavelength and amplitude, and is a so-called meandering orbit curve. Therefore, as the running speed of the railway vehicle increases,
The meandering frequency of the wheel set increases and at a certain speed matches the natural frequency of the primary spring. As a result, the entire bogie becomes meandering greatly, and the stable running of the railcar cannot be maintained. This phenomenon is called snake action, and the traveling speed at which snake action occurs is called the stable limit speed.

し、蛇行動を減衰させる方法がある。As described above, the snake behavior is essentially an unavoidable phenomenon, but it is possible to improve the stability limit speed. As a conventional method for improving the stability limit speed, a method of increasing the spring constant of the primary spring (axial spring) to increase the natural frequency, or as shown in FIG. 12, the vehicle body 8 and the bogie frame 1 are used. There is a method of installing a yaw damper 9 between and to attenuate the snake action.

As shown in FIG. 13, a fluid actuator 10 is installed between the bogie frame 1 and the wheel axle, and information on the track irregularity or the like stored in the storage device 11 in advance is transmitted from an external signal (speed signal, AT).
The signal is read out at any time according to the S signal, the abnormal signal, the emergency stop signal, etc.), the control input is calculated by the controller 12, and the control input is input to the fluid actuator 10.

On the other hand, the "railroad vehicle equipped with a wheel-axis yaw angle control device" disclosed in Japanese Patent Laid-Open No. 3-258655 is effective in improving the riding comfort during normal running, but is effective in suppressing the snake action, which is an unstable phenomenon. It cannot be said that.
