Description

本発明は、鉄道車両用アクティブ操舵ボギーに関するものであって、高速走行する鉄道車両の運転安定性を向上させて鉄道車両の安定性を増進し、鉄道車両が脱線しないようにし、また鉄道車両運転時の車輪及びレールの振動を最小限に抑えることで快適な乗り心地を確保しようとするものである。特に本発明は、ボギーの車輪軸操舵用連結構造が簡単な、てこの作用を利用した鉄道車両用アクティブ操舵ボギーに関するもので、少量の力で連結部を作動させるようてこの作用を利用することで、ボギーの重量を大幅に低減し、また整備を容易にすることができる。   The present invention relates to an active steering bogie for a railway vehicle, which improves the operational stability of a railway vehicle that travels at a high speed, improves the stability of the railway vehicle, prevents the railway vehicle from derailing, and operates the railway vehicle. It is intended to ensure a comfortable ride by minimizing the vibration of the wheels and rails at the time. In particular, the present invention relates to an active steering bogie for railway vehicles using a lever that has a simple connecting structure for steering a wheel shaft of a bogie, and uses this operation to operate the connecting portion with a small amount of force. Thus, the weight of the bogie can be greatly reduced and maintenance can be facilitated.

概して、鉄道車両に使用されるボギーは、車両本体の重量を各々の車輪に均一に分配して車両本体の重量を支持するよう働き、また、鉄道車両の直進又はカーブ運転を容易にするために車両本体に対して自由に回転可能である。   In general, bogies used in railway vehicles serve to support the weight of the vehicle body by evenly distributing the weight of the vehicle body to each wheel, and also to facilitate straight travel or curve driving of the rail vehicle It can freely rotate with respect to the vehicle body.

しかし、従来のボギーによりもたらされる操舵力は、車輪とレール間で発生する過度の遠心力及びガイド重量を軽減するには十分でなく、車輪フランジとレール外側面間の摩擦が高レベルの騒音と振動を発生させるため、乗客の乗り心地を悪化させている。この問題は車輪の摩耗及びレールの損傷をも引き起こし、鉄道車両の脱線といった深刻な事故が起こりうる。   However, the steering force provided by conventional bogies is not sufficient to reduce the excessive centrifugal force and guide weight generated between the wheels and the rails, and the friction between the wheel flanges and the rail outer surface is a high level of noise. Passenger comfort is deteriorated because vibration is generated. This problem also causes wheel wear and rail damage, and serious accidents such as railcar derailment can occur.

上記問題を解決するために、図１にて示す一例のように（図１では、図の右側を正面とする）、アクティブ操舵ボギーの構造はいくつか提案されている。図１に示すように、操舵ボギー１０は、ボギーフレーム１１の前部及び後部に配置される前輪軸及び後輪軸１２、両車輪軸１２の両端に押し込んで設置される車輪１３、及び、ボギーフレーム１１に固定される軸箱１４及びサーボモーター１５を含む。各サーボモーター１５は、前輪軸又は後輪軸１２の軸箱１４といくつかの連結部を介して連結される。   In order to solve the above problem, several active steering bogie structures have been proposed as in the example shown in FIG. 1 (in FIG. 1, the right side of the figure is the front). As shown in FIG. 1, the steering bogie 10 includes a front wheel shaft and a rear wheel shaft 12 disposed at the front and rear portions of the bogie frame 11, wheels 13 that are installed by being pushed into both ends of both wheel shafts 12, and a bogie frame. 11 includes a shaft box 14 and a servo motor 15 that are fixed to 11. Each servo motor 15 is connected to a shaft box 14 of the front wheel shaft or the rear wheel shaft 12 through some connecting portions.

ボギー１０は一対の操舵部を有し、各操舵部は、前輪軸１２と後輪軸１２を別々に操舵するために一つのサーボモーター１５と、それに対応しモーター１５と結合する連結部を含む。   The bogie 10 has a pair of steering units, and each steering unit includes one servo motor 15 and a corresponding coupling unit coupled to the motor 15 for steering the front wheel shaft 12 and the rear wheel shaft 12 separately.

上記のような従来の操舵ボギー１０では、走行鉄道車両が右にカーブする鉄道線路を検知すると、制御装置（図示しない）が信号を発信しサーボモーター１５を始動させる。図２に示すように、各サーボモーター１５は減速装置１６を用いて回転軸を時計回りに回転させる。回転軸に偏心連結された第１駆動連結部１７は、操舵ボギー１０の右後輪軸１２を直接操舵するよう引っ張られる。第２駆動連結部１８は第１追従連結部１９に連結され、ボギー１０の対向する位置に配置される伝達連結部２０を回転させ、前記と同様に伝達連結部２０は第２追従連結部２１を回転させ、それにより第２追従連結部２１に連結される被駆動連結部２２を引っ張るので、被駆動連結部２２は左後輪軸１２を操舵する。   In the conventional steering bogie 10 as described above, when the traveling railway vehicle detects a railway track that curves to the right, a control device (not shown) transmits a signal to start the servo motor 15. As shown in FIG. 2, each servo motor 15 uses a speed reducer 16 to rotate the rotating shaft clockwise. The first drive connecting portion 17 eccentrically connected to the rotating shaft is pulled so as to directly steer the right rear wheel shaft 12 of the steering bogie 10. The second drive connecting portion 18 is connected to the first follower connecting portion 19 and rotates the transmission connecting portion 20 disposed at a position where the bogie 10 is opposed, and the transmission connecting portion 20 is the second follower connecting portion 21 as described above. , Thereby pulling the driven connecting portion 22 connected to the second follower connecting portion 21, so that the driven connecting portion 22 steers the left rear wheel shaft 12.

上記において、サーボモーター１５、第１及び第２駆動連結部１７及び１８、第１及び第２追従連結部１９及び２１、伝達連結部２０、及び、被駆動連結部２２は、操舵ボギー１０の前後部に対称的に配置されるため、前輪軸及び後輪軸１２は各サーボモーター１５の回転により同様に操舵される。   In the above, the servo motor 15, the first and second drive connecting portions 17 and 18, the first and second follow connecting portions 19 and 21, the transmission connecting portion 20, and the driven connecting portion 22 are arranged before and after the steering bogie 10. The front wheel shaft and the rear wheel shaft 12 are steered in the same manner by the rotation of the servo motors 15.

従来の操舵ボギー１０では、走行鉄道車両が左にカーブする鉄道線路を検知すると、制御装置（図示しない）が信号を発信しサーボモーター１５を反時計回りに回転させるため、操舵ボギー１０の前輪軸及び後輪軸１２は図３に示すように操舵される。   In the conventional steering bogie 10, when the traveling railway vehicle detects a railway track that curves to the left, a control device (not shown) transmits a signal to rotate the servo motor 15 counterclockwise. The rear wheel shaft 12 is steered as shown in FIG.

上記に記載される鉄道車両用操舵ボギー１０は、連結部を介してサーボモーター１５の回転を伝達するよう構成され、ボギー１０の前輪軸及び後輪軸１２を操舵する。しかし、このような構成の操舵ボギー１０は連結部の構造が複雑なため整備が困難で、また重量も、サーボモーター１５の回転モーメントを増加するためにサーボモーター１５に固定される減速装置１６の重量が重いため増加する。   The railway vehicle steering bogie 10 described above is configured to transmit the rotation of the servo motor 15 through a connecting portion, and steers the front wheel shaft and the rear wheel shaft 12 of the bogie 10. However, the steering bogie 10 having such a configuration is difficult to maintain because the structure of the connecting portion is complicated, and the weight of the reduction gear 16 fixed to the servo motor 15 in order to increase the rotational moment of the servo motor 15 is also great. Increased due to heavy weight.

本発明は、従来技術における前述の問題を解決するものであって、ボギーの保全性及び操舵反応性を向上するためにボギーの前後輪軸操舵用操舵連結部の構造が簡単であり、それゆえ操舵連結部が減速装置を使用せずにてこの作用に基づくアクチュエータからの少量の力を利用して作動可能である、てこの作用を利用した鉄道車両用アクティブ操舵ボギーを提供することを目的とする。   The present invention solves the above-mentioned problems in the prior art, and the structure of the steering connection portion for front and rear wheel axle steering of the bogie is simple in order to improve the maintainability and steering responsiveness of the bogie. It is an object of the present invention to provide an active steering bogie for a railway vehicle using a lever that can be operated by using a small amount of force from an actuator based on this action without using a reduction gear. .

本発明は、てこの作用を利用した鉄道車両用アクティブ操舵ボギーを提供することを目的とし、ボギーの前後輪軸操舵用操舵連結部がボギーの両側に設けられ、ボギーの両側の前記操舵連結部が反対方向へ各車輪軸を操舵することができるため、連結部の少量移動だけで車輪軸が大幅に移動可能なため、鉄道車両の操舵能力を向上することができる。   An object of the present invention is to provide an active steering bogie for a railway vehicle using the action of a lever, and a steering connection portion for front and rear wheel axle steering of a bogie is provided on both sides of the bogie, and the steering connection portions on both sides of the bogie are Since each wheel shaft can be steered in the opposite direction, the wheel shaft can be moved significantly only by a small amount of movement of the connecting portion, so that the steering ability of the railway vehicle can be improved.

Indicates a steering bogie.

本発明の明細書では、図４及び５の右側を操舵ボギー１００の正面とする。   In the specification of the present invention, the right side of FIGS.

図４及び５に示すように、本発明のてこの作用を利用した鉄道車両用アクティブ操舵ボギー１００は、前輪軸１０２を操舵するために前輪軸１０２の両端の軸箱１０４に連結される前方操舵部２００と、後輪軸１０２を操舵するために後輪軸１０２の両端の軸箱に連結される後方操舵部２００Ａを含む。   As shown in FIGS. 4 and 5, the railway vehicle active steering bogie 100 using the lever action of the present invention is forward-steered connected to axle boxes 104 at both ends of the front wheel shaft 102 in order to steer the front wheel shaft 102.

The front steering unit 200 operates to steer the front wheel shaft 102 of the bogie 100, and the rear steering unit 200A operates to steer the rear wheel shaft 102 of the bogie 100. When the railway vehicle travels along a curved track, the front steering unit 200 and the rear steering unit 200A work to steer the front wheel shaft and the rear wheel shaft 102 so that the rail vehicle can travel smoothly along the curved track.

前方及び後方の各操舵部２００及び２００Ａはアクチュエータ２０１、ボギーフレーム１０１に連結され且つアクチュエータ２０１から力を伝達する駆動連結部２０３及び２０３ａ、軸箱１０４を操舵するよう各々の駆動連結部２０３及び２０３ａに連結される追従連結部２０４及び２０４ａ、及び、ボギー１００の両外側部に配置される駆動連結部２０３及び２０３ａにそれぞれ接続する伝達連結部２０５を含む。   The front and rear steering units 200 and 200A are connected to the actuator 201, the bogie frame 101 and drive connection units 203 and 203a that transmit force from the actuator 201, and the drive connection units 203 and 203a to steer the axle box 104.

Fixed. Thereby, since the weight concerning the both ends of the bogie 100 becomes the same, the driving stability of a railway vehicle increases.

ボギー１００の駆動連結部２０３が前方操舵部２００及び後方操舵部２００Ａのアクチュエータ２０１により駆動されると、上記の構成により、角度変位が伝達連結部２０５を介して駆動連結部２０３から駆動連結部２０３ａへと伝達される。
When the drive connection portion 203 of the bogie 100 is driven by the actuator 201 of the front steering portion 200 and the rear steering portion 200A, the angular displacement is driven from the drive connection portion 203 via the transmission connection portion 205 by the above configuration. Is transmitted to.

駆動連結部２０３は、第１ジョイント２３０に対応する駆動連結部２０３の一部が追従連結部２０４に連結され、駆動連結部２０３のもう一部が伝達連結部２０５に連結され、ボギーフレーム１０１の対向部分にある駆動連結部２０３ａの一端に伝達連結部２０５を介して接続されるように、アクチュエータ２０１に連結される。駆動連結部２０３ａは同様にそのもう一方の端部でボギーフレーム１０１に連結され、追従連結部２０４ａはフレームジョイント２９０の内側に連結される。
In the drive connecting portion 203, a part of the drive connecting portion 203 corresponding to the first joint 230 is connected to the follow connecting portion 204 , another part of the drive connecting portion 203 is connected to the transmission connecting portion 205, and the bogie frame 101 It is connected to the actuator 201 so as to be connected to one end of the drive connecting portion 203a in the opposing portion via the transmission connecting portion 205. Similarly, the drive connecting portion 203a is connected to the bogie frame 101 at the other end thereof, and the follow-up connecting portion 204a is connected to the inside of the frame joint 290 .

すなわち、駆動連結部２０３及び２０３ａが伝達連結部２０５により同方向に回転すると、追従連結部２０４及び２０４ａは逆方向の移動をもたらし、それにより車輪軸１０２を回転させる。   That is, when the drive connecting portions 203 and 203a are rotated in the same direction by the transmission connecting portion 205, the following connecting portions 204 and 204a cause movement in the opposite direction, thereby rotating the wheel shaft 102.

駆動連結部２０３は、力を増幅することでアクチュエータ２０１から追従連結部２０４へと力を伝達するようてことして働く。駆動連結部２０３のフレームジョイント２４０から、アクチュエータ２０１が駆動連結部２０３に連結される第１ジョイント２３０までの距離が、フレームジョイント２４０から、駆動連結部２０３が追従連結部２０４に連結される第２ジョイント２５０までの距離の４倍又はそれ以上であると好ましい。   The drive connecting portion 203 works by transmitting the force from the actuator 201 to the tracking connecting portion 204 by amplifying the force. The distance from the frame joint 240 of the drive connection portion 203 to the first joint 230 where the actuator 201 is connected to the drive connection portion 203 is the second distance from the frame joint 240 to which the drive connection portion 203 is connected to the follow-up connection portion 204. It is preferable that the distance to the joint 250 is four times or more.

前述のように、駆動連結部２０３及び２０３ａは車輪軸１０２を操舵するために力を増幅させることによってアクチュエータ２０１から追従連結部２０４及び２０４ａへと力を伝達するてことして働く。従って、アクチュエータ２０１が周知の電動リニアモーターの形態で実行される場合でも、減速器を使用せずに駆動連結部２０３及び２０３ａにより車輪軸１０２を満足に操舵できる。   As described above, the drive connecting portions 203 and 203a work by transmitting force from the actuator 201 to the follower connecting portions 204 and 204a by amplifying the force to steer the wheel shaft 102. Therefore, even when the actuator 201 is executed in the form of a known electric linear motor, the wheel shaft 102 can be satisfactorily steered by the drive connecting portions 203 and 203a without using a speed reducer.

アクチュエータ２０１は、電動リニアモーターだけでなく油圧式アクチュエータ又は空気圧式アクチュエータでも実行可能であるが、油圧又は空気圧式アクチュエータはアクチュエータポンプに加えて油圧又は空気圧パイプを更に必要とし、そのため構造が複雑になる。従って、電動リニアモーターの使用が好ましい。   The actuator 201 can be implemented by not only an electric linear motor but also a hydraulic actuator or a pneumatic actuator, but the hydraulic or pneumatic actuator further requires a hydraulic or pneumatic pipe in addition to the actuator pump, which makes the structure complicated. . Therefore, it is preferable to use an electric linear motor.

駆動連結部２０３及び２０３ａが追従連結部２０４及び２０４ａに連結される第２ジョイント２５０及び第５ジョイント２８０、及び、追従連結部２０４及び２０４ａが軸箱１０４に連結される軸箱ジョイント２２０は、球状ジョイントで実行されるのが好ましい。従って、第２及び第５ジョイント２５０及び２８０、及び軸箱ジョイント２２０のような球状ジョイントは、ボギー１００の車輪軸１０２の操舵において追従連結部２０４及び２０４ａにより生成される車輪軸１０２の軸方向変位量を吸収することができるので、車輪軸１０２は制限無く自由に回転可能となる。
The second joint 250 and the fifth joint 280 drive links 203 and 203a are connected to the follower links 204 and 204a, and axle box joints 220 of follower links 20 4 and 20 4 a is connected to the axle boxes 104 Is preferably carried out with a spherical joint. Accordingly, spherical joints such as the second and fifth joints 250 and 280 and the axle box joint 220 are axial displacements of the wheel shaft 102 that are generated by the follower couplings 204 and 204a during steering of the wheel shaft 102 of the bogie 100. Since the amount can be absorbed, the wheel shaft 102 can freely rotate without limitation.

さらに、鉄道車両が走行中に発生させる振動、又は追従連結部２０４及び２０４ａが車輪軸１０２を回転させる際に発生させる振動又は衝撃を吸収するために、ゴム製ブッシング１０７が各球状ジョイントの受け口１０６に挿入されることで、鉄道車両の運転安定性が促進される。   Further, in order to absorb vibrations generated while the railway vehicle is traveling, or vibrations or impacts generated when the following connecting portions 204 and 204a rotate the wheel shaft 102, the rubber bushing 107 is provided with the receiving port 106 of each spherical joint. As a result, the driving stability of the railway vehicle is promoted.

以下、上記構造を有する本発明の操作を説明する。   The operation of the present invention having the above structure will be described below.

本発明の操舵ボギー１００を有する走行鉄道車両が線路のカーブ部を検知すると、制御装置（図示しない）はボギー１００の車輪１０２を操舵するようアクチュエータ２０１の操作を始動する操舵信号を発信するので、鉄道車両は線路のカーブ部に沿って安定して走行できる。   When the traveling railway vehicle having the steering bogie 100 of the present invention detects the curve portion of the track, the control device (not shown) transmits a steering signal for starting the operation of the actuator 201 to steer the wheel 102 of the bogie 100. The railway vehicle can travel stably along the curve portion of the track.

アクチュエータ２０１は、線路のカーブ部が検知される際の制御装置が発信する操舵信号に反応して作動する。そして、ボギー１００のフレーム１０１の両端に固定される複数のアクチュエータ２０１は反対方向に作動して車輪軸１０２を操舵する。すなわち、一方のアクチュエータ２０１のロッド２０２が突出する際、もう一方のアクチュエータ２０１のロッド２０２はアクチュエータ２０１の筐体へと後退する。   The actuator 201 operates in response to a steering signal transmitted from the control device when the curve portion of the track is detected. A plurality of actuators 201 fixed to both ends of the frame 101 of the bogie 100 operate in opposite directions to steer the wheel shaft 102. That is, when the rod 202 of one actuator 201 protrudes, the rod 202 of the other actuator 201 moves backward to the housing of the actuator 201.

図５に示すボギーは、図において左から右へと線路に沿って移動し、ボギーの左右はその移動方向に基づいて定められ、ボギーの移動方向は前面又は前方方向と想定する。   The bogie shown in FIG. 5 moves along the track from left to right in the figure, and the left and right sides of the bogie are determined based on the moving direction, and the moving direction of the bogie is assumed to be the front or the front direction.

走行鉄道車両が右へカーブする線路箇所に達すると、制御装置（図示しない）はカーブ路線を検知し操舵信号を発信する。制御装置からの操舵信号に反応して、ボギーフレーム１０１の右部に固定される後方操舵部２００Ａのアクチュエータ２０１のロッド２０２は、図６に示すように、フレームジョイント２４０を中心に駆動連結部２０３を反時計回りに回転させるよう突出する。反時計回りに回転する駆動連結部２０３は、後輪軸１０２の右軸箱１０４に連結される追従連結部２０４を引っ張る。そして、伝達連結部２０５を介して駆動連結部２０３に連結されるボギー１００の後方操舵部２００Ａの左駆動連結部２０３ａは、フレームジョイント２９０を中心に反時計回りに回転させ、後輪軸１０２の左軸箱１０４と追従連結部２０４ａを押して車輪軸１０２を回転させる。
When the traveling railway vehicle reaches a track section that curves to the right, a control device (not shown) detects a curve route and transmits a steering signal. The rod 202 of the actuator 201 of the rear steering unit 200A that is fixed to the right part of the bogie frame 101 in response to a steering signal from the control device, as shown in FIG. Projects to rotate 3 counterclockwise. The drive connecting portion 203 that rotates counterclockwise pulls the follow-up connecting portion 204 that is connected to the right axle box 104 of the rear wheel shaft 102. Then, the left drive connecting portion 203a of the rear steering portion 200A of the bogie 100 connected to the drive connecting portion 203 via the transmission connecting portion 205 rotates counterclockwise around the frame joint 290, and the left wheel shaft 102 The wheel axle 102 is rotated by pushing the axle box 104 and the follower connecting portion 204a.

ここで、ボギー１００の右駆動連結部２０３は、アクチュエータ２０１に連結される第１ジョイント２０３、及び追従連結部２０４に連結される第２ジョイント２５０によりフレームジョイント２４０の両側に設けられ、追従連結部２０４を引っ張るように反時計回りに回転する。反対に、ボギー１００の左駆動連結部２０３ａは、駆動連結部２０３ａと伝達連結部２０５が連結される第４ジョイント２７０及びフレーム結合部を有し、このフレーム結合部により、駆動連結部２０３ａが追従連結部２０４ａに連結される第５ジョイント２８０の両側でボギーフレーム１０１に駆動連結部２０３ａが連結され、反時計回りに回転し、それにより追従連結部２０４ａを押す。   Here, the right drive connecting portion 203 of the bogie 100 is provided on both sides of the frame joint 240 by the first joint 203 connected to the actuator 201 and the second joint 250 connected to the following connecting portion 204, and the following connecting portion. Rotate counterclockwise to pull 204. On the other hand, the left drive connecting portion 203a of the bogie 100 has a fourth joint 270 and a frame connecting portion for connecting the driving connecting portion 203a and the transmission connecting portion 205, and the drive connecting portion 203a follows the frame connecting portion. The drive connection portion 203a is connected to the bogie frame 101 on both sides of the fifth joint 280 connected to the connection portion 204a and rotates counterclockwise, thereby pushing the follow-up connection portion 204a.

後方操舵部２００Ａにより回転するボギー１００の後輪軸１０２が回転すると同時に、ボギーの左部に固定される前方操舵部２００のアクチュエータ２０１のロッド２０２は、制御装置からの操舵信号に反応してアクチュエータ２０１の筐体へと後退し、それにより駆動連結部２０３はフレームジョイント２４０を中心に反時計回りに回転する。反時計回りに回転する駆動連結部２０３は、前輪軸１０２の左軸箱１０４に連結される追従連結部２０４を押し、伝達連結部２０５を介して駆動連結部２０３に接続されるボギー１００の前方操舵部２００の右駆動連結部２０３ａは、前輪軸１０２の右追従連結部２０４ａを引っ張るようフレームジョイント２９０を中心に反時計回りに回転し、それにより車輪軸１０２を回転させる。   At the same time as the rear wheel shaft 102 of the bogie 100 rotated by the rear steering unit 200A rotates, the rod 202 of the actuator 201 of the front steering unit 200 fixed to the left part of the bogie responds to the steering signal from the control device, and the actuator 201 Accordingly, the drive connecting portion 203 rotates counterclockwise around the frame joint 240. The drive connecting portion 203 that rotates counterclockwise pushes the follow connecting portion 204 that is connected to the left axle box 104 of the front wheel shaft 102, and the front of the bogie 100 that is connected to the drive connecting portion 203 via the transmission connecting portion 205. The right drive connecting portion 203a of the steering portion 200 rotates counterclockwise around the frame joint 290 so as to pull the right following connecting portion 204a of the front wheel shaft 102, thereby rotating the wheel shaft 102.

ここで、ボギー１００の左駆動連結部２０３は、反時計回りに回転するように、フレームジョイント２３０の両側に第１ジョイント２３０及び第２ジョイント２５０を備え、それにより追従連結部２０４を押すが、一方、ボギー１００の右駆動連結部２０３ａは、反時計回りに回転するように、第５ジョイント２８０の両側に第４ジョイント２７０及びフレームジョイント２９０を備え、それにより追従連結部２０４ａを引っ張る。   Here, the left drive connecting portion 203 of the bogie 100 includes the first joint 230 and the second joint 250 on both sides of the frame joint 230 so as to rotate counterclockwise, thereby pushing the tracking connecting portion 204. Meanwhile, the right drive connecting portion 203a of the bogie 100 includes a fourth joint 270 and a frame joint 290 on both sides of the fifth joint 280 so as to rotate counterclockwise, thereby pulling the follower connecting portion 204a.

上記のように、走行鉄道車両が右へカーブする線路箇所に到達すると、制御装置（図示しない）は線路のカーブ箇所を検知し、操舵信号を発信する。制御装置からの操舵信号に反応して、後方操舵部２００Ａのアクチュエータ２０１のロッド２０２は突出し、前方操舵部２００のアクチュエータ２０１のロッド２０２はアクチュエータ筐体へと後退する。その結果ボギー１００の前輪軸及び後輪軸１０２が回転し、図７に示すように、鉄道車両は右へカーブした線路箇所に沿って安定した走行が可能となる。   As described above, when the traveling railway vehicle reaches the track part that curves to the right, the control device (not shown) detects the curve part of the track and transmits a steering signal. In response to the steering signal from the control device, the rod 202 of the actuator 201 of the rear steering unit 200A protrudes, and the rod 202 of the actuator 201 of the front steering unit 200 moves backward to the actuator housing. As a result, the front wheel shaft and the rear wheel shaft 102 of the bogie 100 rotate, and the railway vehicle can stably travel along the track portion curved to the right as shown in FIG.

さらに、走行鉄道車両が左へカーブする線路箇所に到達すると、制御装置（図示しない）は線路のカーブ箇所を検知し、操舵信号を発信する。制御装置からの操舵信号に反応して、後方操舵部２００Ａのアクチュエータ２０１のロッド２０２は、図８に示すようにアクチュエータ筐体へと後退し、前方操舵部２００のアクチュエータ２０１のロッド２０２は突出する。その結果ボギー１００の前輪軸及び後輪軸１０２が回転し、鉄道車両は左へカーブした線路箇所に沿って安定した走行が可能となる。   Further, when the traveling railway vehicle reaches a track portion that curves to the left, a control device (not shown) detects the curve portion of the track and transmits a steering signal. In response to the steering signal from the control device, the rod 202 of the actuator 201 of the rear steering unit 200A moves backward to the actuator housing as shown in FIG. 8, and the rod 202 of the actuator 201 of the front steering unit 200 protrudes. . As a result, the front wheel shaft and the rear wheel shaft 102 of the bogie 100 rotate, and the railway vehicle can stably travel along the track portion curved to the left.

第２ジョイント２５０、第５ジョイント２８０、及び追従連結部２０４及び２０４ａの軸箱ジョイント２２０は、球状ジョイントで実行される。球状ジョイントは、追従連結部２０４及び２０４ａがボギー１００の車輪軸１０２を操舵する際に発生する車輪軸１０２の軸方向移動を吸収するため、車輪軸１０２は軸方向移動によって制限されることなく自由に回転でき、鉄道車両はカーブした線路に沿って安定した走行が可能となる。   The second joint 250, the fifth joint 280, and the axle box joint 220 of the follower connecting portions 204 and 204a are implemented as spherical joints. The spherical joint absorbs the axial movement of the wheel shaft 102 that occurs when the follower connecting portions 204 and 204a steer the wheel shaft 102 of the bogie 100, so that the wheel shaft 102 is free without being restricted by the axial movement. The railway vehicle can travel stably along a curved track.

ここで、ゴム製ブッシング１０７がボール１０５と球状ジョイントの受け口１０６間に挿入され、鉄道車両の走行時に発生する振動、又は追従連結部２０４及び２０４ａが車輪軸１０２を回転する際に発生する振動及び衝撃を吸収する。従って、鉄道車両の運転安定性が促進される。   Here, the rubber bushing 107 is inserted between the ball 105 and the joint 106 of the spherical joint, and vibration generated when the railway vehicle travels, or vibration generated when the follower connecting portions 204 and 204a rotate the wheel shaft 102, and Absorbs shock. Therefore, driving stability of the railway vehicle is promoted.
