この発明は、鉄道車両等の軌道車両用走行台車において
曲線半径の小さい小曲線を通過できるようにした走行台
車に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a traveling bogie for a track vehicle such as a railway vehicle, which is capable of passing through short curves with small curve radii.
従来の技術
軌道車両用走行台車における車輪は輪軸に圧入固定され
ており、軸上で回転できないため、曲線路を走行する場
合には、曲線外軌と内軟の間に行程差に基いて、軌条と
車輪踏面の間には必然的に滑りが起る。そのため、外軌
側車輪と内鉄側車輪との間に直径差を付けて行程差を吸
収する必要がある。Conventional technology The wheels of a running bogie for a track vehicle are press-fitted onto the wheel axle and cannot rotate on the axle. Slippage inevitably occurs between the rail and the wheel tread. Therefore, it is necessary to provide a diameter difference between the outer rail side wheels and the inner rail side wheels to absorb the difference in stroke.
従来の走行台車は、円錐状踏面を有する車輪を使用して
、曲線通過の際の外軌と内軟の行程差を、輪軸が左右に
ずれることにより外軌側車輪と内鉄側車輪の直径差を得
て、この直径差により解消していた。Conventional running bogies use wheels with conical treads to compensate for the difference in stroke between the outer track and the inner track when passing through a curve, by shifting the wheel axle to the left or right, thereby reducing the diameter of the outer track wheel and the inner track wheel. A difference was obtained, and this difference in diameter was used to eliminate the difference.
第７図に示すように１５曲線の曲率半径をＲ１軌間を２
ｂ、軌間中央点の半径をｒ、外軌側車輪と内鉄側車輪の
車輪半径差を△ｒとすれば、△ｒは下記式で表わされる
。As shown in Figure 7, the radius of curvature of the 15 curve is
b, the radius of the center point of the gauge is r, and the wheel radius difference between the outer rail side wheel and the inner rail side wheel is △r, then △r is expressed by the following formula.
△ｒ＝ハ匹（・、・工＝迫Ｌ）
ＲＲ２ｂ
これは、第８図に示すような関数となり、曲線の曲率半
径Ｒが小さいとき大きな車輪半径差△ｒが必要となる。△r=Ha (・・・Work=Surface L) RR2b This becomes a function as shown in FIG. 8, and when the radius of curvature R of the curve is small, a large wheel radius difference △r is required.
又、円錐状車輪踏面では、車輪半径差Δｒは踏面のずれ
る量によって変化する。Further, in the case of a conical wheel tread, the wheel radius difference Δr changes depending on the amount of displacement of the tread.
現在の車輪幅１２５ ｍｍ〜１３５ｍｍ、実用可能勾配
置７５程度では、得られる車輪半径差Δｒは、輪軸で、
１４ｍｍ程度が限度である。With the current wheel width of 125 mm to 135 mm and a practical slope of about 75 mm, the resulting wheel radius difference Δr at the wheel axle is
The limit is about 14 mm.
この条件のもとて軌間距離２ｂが１０６７ｍｍの場合、
Ｒ＝２ｂ−ｒ＝ １０６７×α４３ ＝ ３ａ△ｒ
０．０１４
となり、計算上は半径３０ｍ以下であるが、実用上は半
径５０ｍ以下の小ざい曲線では円滑な通過はできない。Under these conditions, if the gauge distance 2b is 1067 mm,
R=2b-r=1067×α43=3a△r
0.014, which is calculated as a radius of 30 m or less, but in practice, a small curve with a radius of 50 m or less cannot be passed smoothly.
又、小さい曲線を無理に通過すれば、外軌側車輪と内軟
側車輪の直径差が十分に確保できないため、車輪フラン
ジの異常摩耗、きしり音、あるいは軌条の異常摩耗が発
生する。Furthermore, if the vehicle is forced to pass through a small curve, a sufficient difference in diameter between the outer wheel and the inner soft wheel cannot be ensured, resulting in abnormal wear of the wheel flange, creaking noise, or abnormal wear of the rail.
さらに、曲線路には遠心力の作用を緩和するためカント
が付けられているが、半径の小さい曲線路では大きなカ
ントが必要である。このような大きなカントを付けた曲
線路で車両が停止すれば、車両は転倒する危険がある。Further, although curved roads are provided with cant to alleviate the effect of centrifugal force, curved roads with a small radius require a large cant. If a vehicle stops on a curved road with such a large cant, there is a risk that the vehicle will overturn.
そのため、従来から小曲線通過の際の外軌と内軟の行程
差を解消する方法として、左右の車輪が独立して回転す
る独立車輪方式が知られている。Therefore, an independent wheel system in which the left and right wheels rotate independently has been known as a method of eliminating the difference in stroke between the outer track and the inner track when passing through a small curve.
この独立車輪方式の車輪を駆動する場合は、輪軸に差動
歯車装置を設けてモータ駆動する方法と歯車装置を介し
てモータ駆動する駆動輪軸の片側に車輪を嵌着し、他側
に軸受を介して回転自在に車輪を取付ける方式がある。When driving wheels using this independent wheel system, there are two methods: one is to install a differential gear on the wheel axle and drive the motor, and the other is to fit the wheel on one side of the driving wheel axle that is driven by the motor via the gear device, and to install a bearing on the other side. There is a method of attaching wheels so that they can rotate freely.
発明が解決しようとする問題点
前記のごとく、輪軸に圧入した車輪を有する一般の走行
台車は小曲線の通過はできない。Problems to be Solved by the Invention As mentioned above, general traveling bogies having wheels press-fitted into wheel axles cannot pass through short curves.
又、小曲線の通過を可能にした独立歯車を使った走行台
車は、走行時に車両が左右方向のいずれかに片寄った場
合、車両中心が軌道中心に一致するように復元する機能
がないため、片寄ったまま直線を走行することになる。Additionally, the traveling bogies that use independent gears that enable passage through small curves do not have the ability to restore the center of the vehicle to the center of the track if the vehicle shifts to either the left or right direction while traveling. You will be driving in a straight line with the vehicle leaning to one side.
その結果、車両は軌道の狂いに沿って走るため、乗り心
地が直線で悪化したり、車輪の片方向のみが異常に摩耗
する問題があった。As a result, the vehicle runs along an irregular track, leading to problems such as poor riding comfort in a straight line and abnormal wear of wheels in only one direction.
又、差動歯車装置を用いた独立車輪方式は製作費が高く
、保守点検に手間がかかり、片側動輪、他側従輪の独立
車輪方式は構造は簡単であるが、片側駆動のため牽引力
が車両の中心からずれ、車両が片寄りやすい。この片寄
りを解消するには前軸と俊軸において動輪と従輪が互い
に逆位置になるようにすればよいが、小曲線通過のため
には前輪と後輪で速度差をつける必要が生じモータ制御
が複雑となる。In addition, the independent wheel system using a differential gear device is expensive to manufacture and takes time to maintain and inspect, while the independent wheel system with a driving wheel on one side and a trailing wheel on the other side has a simple structure, but because it is driven on one side, the traction force is lower than the vehicle. is off-center, and the vehicle tends to lean to one side. In order to eliminate this deviation, it is possible to have the driving wheels and driven wheels on the front and quick axles in opposite positions, but in order to pass through small curves, it is necessary to create a speed difference between the front and rear wheels, so the motor Control becomes complicated.
以上のごとく、従来は小曲線を通過するための走行台車
としては満足できるものはなかった。この発明は、かか
る現状にかんがみ、半径の小さい曲線路を安全かつ円滑
