Japanese Patent Laid-Open No. 06-255486 JP 09-301157 A

磁気浮上式の車両は、モジュールと車体の間に空気バネが装備されて緩衝が図られる。車両がカーブを通過する際に、モジュールと車体の間に横方向のズレが発生する。この際に、空気バネに横方向の変位が発生するとともに軸まわりのネジレが生ずる。このネジレにより空気バネの耐久性が劣化する問題がある。
本発明の目的は、常電導吸引型磁気浮上式車両の台車（モジュール）に装備される空気バネを提供するものである。 A magnetically levitated vehicle is equipped with an air spring between the module and the vehicle body to be buffered. When the vehicle passes the curve, a lateral shift occurs between the module and the vehicle body. At this time, a lateral displacement occurs in the air spring and a twist about the axis occurs. There is a problem that the durability of the air spring deteriorates due to this twist.
The objective of this invention is providing the air spring with which the trolley | bogie (module) of a normal conducting attraction type magnetic levitation type vehicle is equipped.

上記目的を達成するために、本発明の常電導吸引型磁気浮上式車両は、レールの下面に対向して配設される常電導磁石を有する複数のモジュールと、モジュールに対して空気バネを介して支持される車体を備え、空気バネはモジュールのフレームに設けられた円筒形状の凹部に挿入されるとともに、空気バネを支持するベースプレートとフレームの凹部の底部との間に配置される円すいころ軸受を備えるものである。
そして、空気バネの外周部とモジュールのフレームの凹部の壁面との間には所定の間隙が設けられる。 In order to achieve the above object, a normal conducting attraction type magnetically levitated vehicle according to the present invention includes a plurality of modules having normal conducting magnets arranged opposite to the lower surface of the rail, and air springs to the modules. A tapered roller bearing provided between the base plate supporting the air spring and the bottom of the recessed portion of the frame, and the air spring is inserted into a cylindrical recessed portion provided in the frame of the module. Is provided.
A predetermined gap is provided between the outer peripheral portion of the air spring and the wall surface of the recess of the module frame.

本発明によれば、常電導吸引型磁気浮上式車両の台車（モジュール）がカーブを通過する際に空気バネにかかるネジレ応力を吸収することができる。   ADVANTAGE OF THE INVENTION According to this invention, the twisting stress concerning an air spring can be absorbed when the trolley | bogie (module) of a normal conducting attraction type magnetic levitation type vehicle passes a curve.

図１は本発明を実施する磁気浮上車両の外観を示す説明図、図２は側面図である。
本実施例にあっては、１編成の電車は３両の車両１Ａ，１Ｂ，１Ｃにより構成され、軌道２上を走行する。
各車両はその下部に、台車に相当するモジュール２０を備える。モジュール２０は、各車両の両側部に５基づつ、合計１０基装備される。 FIG. 1 is an explanatory view showing the appearance of a magnetically levitated vehicle embodying the present invention, and FIG. 2 is a side view.
In this embodiment, one train is composed of three vehicles 1A, 1B, and 1C and travels on the track 2.
Each vehicle includes a module 20 corresponding to a carriage at the lower part thereof. A total of ten modules 20 are installed, five on each side of each vehicle.

図３は、モジュール２０に備えられる電磁石と軌道２の関係を示す説明図である。
軌道２は、コンクリート等でつくられる基盤３上に置かれる枕木５と、枕木５の両側部に固定されるレール６を備える。レール６は、磁性材料でつくられ、下方に向けて八字状に突出する凸部６ａ，６ｂを有する。
レール６の上面には、推進用のリニアモータのリアクションプレート７がとりつけられる。 FIG. 3 is an explanatory diagram showing the relationship between the electromagnets provided in the module 20 and the track 2.
The track 2 includes sleepers 5 placed on a base 3 made of concrete or the like, and rails 6 fixed to both sides of the sleepers 5. The rail 6 is made of a magnetic material and has convex portions 6a and 6b that protrude downward in an eight-letter shape.
A reaction plate 7 of a linear motor for propulsion is attached to the upper surface of the rail 6.

基盤３の両側には、支柱４ａを介して給電用の送電線４が配設される。
モジュール２０は、電磁石のコア３０を有し、コイル３２が巻かれる。送電線４に接するパンタグラフ３４は、給電を受け、コイル３２に電流を送る。
コイル３２に流れる電流によりコアに発生する磁力により、モジュール２０はレール６に向けて吸引され、矢印Ｂ方向に浮上する。
浮上する距離は、約８ｍｍに設定される。ギャップセンサ６０は、この浮上距離を監視していて、浮上距離を一定に保つようにコイル３２へ送る電流値を制御する。 On both sides of the base 3, power transmission lines 4 are disposed via support columns 4a.
The module 20 has an electromagnet core 30 around which a coil 32 is wound. The pantograph 34 in contact with the power transmission line 4 receives power and sends current to the coil 32.
The module 20 is attracted toward the rail 6 by the magnetic force generated in the core by the current flowing through the coil 32, and floats in the direction of arrow B.
The flying distance is set to about 8 mm. The gap sensor 60 monitors the flying distance, and controls the current value sent to the coil 32 so as to keep the flying distance constant.

コア３０に両側には、上向きの凸部３０ａ，３０ｂが設けられる。このコア３０の凸部３０ａ，３０ｂとレール６の突部６ａ，６ｂが対向することにより、車体１０が矢印Ａ方向に移動したときにも、常に正常な位置に戻る力が発生する。
モジュール２０の下面には、リニアモータのコイル４０が装備されており、レール６の上面に固定したリアクションプレート７の間で車両の推進力を発生させる。
モジュール２０の下面には、浮上が行われない間に、レール６上に車両を支持するための支持装置５０が設けられる。 On the both sides of the core 30, upward convex portions 30a and 30b are provided. When the protrusions 30a and 30b of the core 30 and the protrusions 6a and 6b of the rail 6 face each other, a force that always returns to a normal position is generated even when the vehicle body 10 moves in the arrow A direction.
A linear motor coil 40 is mounted on the lower surface of the module 20 to generate a propulsive force of the vehicle between the reaction plates 7 fixed to the upper surface of the rail 6.
A support device 50 is provided on the lower surface of the module 20 to support the vehicle on the rail 6 while the levitation is not performed.

図４は、１０基のモジュール２０の連結構造を示し、各モジュール２０は、摺動台７０を介して連結される。
矢印Ｆで示す車両の進行方向の第１と第２のモジュールの間に配設される第２の摺動台７０ｂと、第４と第５のモジュールの間に配設される第５の摺動台７０ｅは車体１０側に連結される。その他の摺動台は全体を符号８０で示すリンクにより連結される。 FIG. 4 shows a connection structure of ten modules 20, and each module 20 is connected via a slide base 70.
A second slide 70b disposed between the first and second modules in the vehicle traveling direction indicated by arrow F, and a fifth slide disposed between the fourth and fifth modules. The moving base 70e is connected to the vehicle body 10 side. The other slides are connected by a link denoted as a whole by 80.

図５は、モジュール２０の平面図である。各モジュール２０は、フレーム２００を有し、左右のフレーム２００はリンクアーム２１０で連結される。各フレーム２００の端部には空気バネ３００が装備される。   FIG. 5 is a plan view of the module 20. Each module 20 has a frame 200, and the left and right frames 200 are connected by a link arm 210. An air spring 300 is provided at the end of each frame 200.

図６は、車両が矢印Ｆ１方向に進行して半径５０ｍのカーブを通過する際のモジュール２０の姿勢を示す。矢印Ｈ１，Ｈ２は、空気バネ３００とモジュールのフレーム２００が水平方向に許容された最大移動量である３０ｍｍ偏移した時のモジュール２０の移動方向を示す。 Figure 6 shows the orientation of the module 20 when the vehicle passes through a curve of radius 50m by proceeding direction of arrow F 1. Arrows H 1 and H 2 indicate the movement direction of the module 20 when the air spring 300 and the module frame 200 are shifted by 30 mm, which is the maximum movement amount allowed in the horizontal direction.

図７は、空気バネ３００の取付構造の詳細を示す。
モジュールのフレーム２００には、円筒形状の凹部２５０が設けられ、空気バネ３００が挿入される。車両１０の床構体１００には、ブラケット１２０がとりつけられる。ブラケット１２０に螺合される取付部材１１０が空気バネ３００の上部に固着される。取付部材１１０とフレーム２００の間にはブーツ１３０がとりつけられ、空気バネ３００を保護する。 FIG. 7 shows details of the mounting structure of the air spring 300.
The frame 200 of the module is provided with a cylindrical recess 250, and the air spring 300 is inserted therein. A bracket 120 is attached to the floor structure 100 of the vehicle 10. A mounting member 110 screwed to the bracket 120 is fixed to the upper portion of the air spring 300. A boot 130 is attached between the mounting member 110 and the frame 200 to protect the air spring 300.

空気バネ３００の下部には、支持部材３１０とブラケット３２０がとりつけられ、ブラケット３２０の下面にはベースプレート３３０が設けられる。モジュールのフレーム２００の円筒形状の凹部２５０の底部とベースプレート３３０の間には円すいころ軸受４００が配置される。円すいころ軸受４００はベースプレート３３０側のレース４２０と、フレーム２００側のレース４１０を有し、両レース４１０，４２０の間に円すいころ４３０が配される。   A support member 310 and a bracket 320 are attached to the lower part of the air spring 300, and a base plate 330 is provided on the lower surface of the bracket 320. A tapered roller bearing 400 is disposed between the bottom of the cylindrical recess 250 of the module frame 200 and the base plate 330. The tapered roller bearing 400 includes a race 420 on the base plate 330 side and a race 410 on the frame 200 side, and a tapered roller 430 is disposed between the races 410 and 420.

車両がカーブ等を通過する際には、車体１０とモジュール２０の間に横方向のズレが発生する。空気バネ３００は内部に空気Ａ１が充填された状態で、その外周部とモジュール２０のフレーム２００の凹部２５０の壁面との間には３０ｍｍ程度の間隙Ｇ１が形成されている。
空気バネ３００は、この間隙Ｇ１内で変位して横方向のズレを吸収する。 When the vehicle passes through a curve or the like, a lateral shift occurs between the vehicle body 10 and the module 20. The air spring 300 is filled with air A 1, and a gap G 1 of about 30 mm is formed between the outer periphery of the air spring 300 and the wall surface of the recess 250 of the frame 200 of the module 20.
Air spring 300 absorbs the displacement of laterally displaced within the gap G 1.

図６に示すように、カーブを通過する際には左右のモジュール２０が平面上で、菱形に変形する。この作用によって、空気バネ３００は軸まわりのネジレを受ける。
円すいころ軸受４００は、空気バネ３００のネジレを回転により吸収する。これにより、空気バネ３００にネジレ応力が加わることが防止され、ゴム等の材料でつくられる空気バネ３００の損傷が防止される。 As shown in FIG. 6, when passing through the curve, the left and right modules 20 are deformed into a rhombus on the plane. By this action, the air spring 300 receives a twist about the axis.
The tapered roller bearing 400 absorbs torsion of the air spring 300 by rotation. This prevents twisting stress from being applied to the air spring 300 and prevents damage to the air spring 300 made of a material such as rubber.
