かに曲線を通過するこを可能にする操舵台車に関する。Description: TECHNICAL FIELD The present invention relates to a steering bogie that enables wheels to smoothly pass through a curve when a railroad vehicle performs a curve run.
（従来の技術） 鉄道車両の曲線通過時に於いて、従来の台車構造では
車輪の回転方向が曲線の接線方向と一致しておらず、こ

理由で従来から線路の曲線半径ごとに安全面、経済面等
を考慮して列車の最高通過速度を決めてきた。(Prior Art) When a railway vehicle passes through a curve, in the conventional bogie structure, the rotation direction of the wheel does not coincide with the tangential direction of the curve, and therefore exists between the wheel and the wheel contact portion of the track. An angle had arisen. Problems caused by this are expansion of the gauge due to lateral pressure generated between the wheel and the track, generation of squeaky noise, wear of the wheel and the track, and repair of a tightening device for the track. For these reasons, the maximum passing speed of a train has been conventionally determined in consideration of safety, economy, etc. for each curve radius of the track.

車構造上からは自己操舵台車の開発が進められてきた。
しかしながら、この台車は機構の複雑さ等の割には走行
性能の向上が不十分であって上記の問題点の解決には至
らず、いまだに実用化されていない。On the other hand, in order to shorten the time required to reach the destination, it has been strongly desired to improve the speed at which the trainees pass through the curve. In Japan, the development of self-steering bogies has been promoted from the bogie structure.
However, this bogie has not sufficiently improved the running performance in spite of the complexity of the mechanism or the like, and has not solved the above-mentioned problems, and has not yet been put to practical use.
これらにより、列車の曲線通過性能の優れた台車の技
術開発が要望されていた。For these reasons, there has been a demand for technical development of a bogie having excellent train passing performance on a curve.
（本発明が解決しようとする問題点） 本発明はこのような現況にかんがみ、従来の台車の車

的に結ばれているため、内輪と外輪とが通過する曲線の
半径差による微小なスリップが発生することがあるが、
独立車輪の場合には左右の車輪がそれぞれ個別に回転す
るので、このような事象は発生しない。(Means for Solving the Problems) In order to solve the above problems, it is necessary that the rotation direction of the wheel always coincides with the tangential direction of the curve while the wheel passes through the curve. If this is combined with the employment of independent wheels, theoretically, it is possible to obtain an ideal curve-passing performance compared with a normal left and right integrated wheel. In other words, in a normal wheel, even if the rotation direction of the wheel is steered in the tangential direction of the curve, the right and left wheels are fixedly connected by one common axis, so the curve through which the inner and outer wheels pass May cause a slight slip due to the difference in radius of
In the case of independent wheels, such a phenomenon does not occur because the left and right wheels individually rotate.

Next, from the difference in the number of rotations and the train speed, the amount of steering of the wheel required to make the direction of rotation of the wheel coincide with the tangential direction of the curve is calculated, and the calculation result is transmitted to the mobile device. The moving device steers the left and right wheels according to the calculation result, so that the rotation direction of the wheels can always match the tangential direction of the curve.
