Description

本発明は、２つの車輌を前後に連接した連接車輌に関する。   The present invention relates to an articulated vehicle in which two vehicles are joined in the front-rear direction.

前後に連接された２つの車輌の連接箇所に台車を配置した構成は、特許文献１において提案されている。この特許文献１の図６とその関連箇所には、前後の車輌の連接部に台車を配置し、この台車の台車枠と前後の車輌間にそれぞれアクチュエータを介設し、このアクチュエータを駆動することで自己操舵の補助を行うことが記載されている。   Patent Document 1 proposes a configuration in which a carriage is arranged at a connection position of two vehicles connected in the front-rear direction. In FIG. 6 of this Patent Document 1 and related portions, a carriage is arranged at the connecting portion of the front and rear vehicles, and an actuator is interposed between the carriage frame of the carriage and the front and rear vehicles, and the actuator is driven. Describes that self-steering assistance is provided.

また、特許文献２には前後に連接された２つの車輌の連接箇所ではないが、一方の車輌の端部に一軸台車を配置し、この一軸台車と他方の車輌とをリンクで連結するとともに、台車の軸受箱と車体間に台車の左右動を抑制するダンパを設け、車体と輪軸との過大な左右方向の変位を防止することが開示されている。   In addition, in Patent Document 2, although it is not a connection location of two vehicles connected in the front-rear direction, a uniaxial carriage is arranged at the end of one vehicle, and the uniaxial carriage and the other vehicle are connected by a link, It is disclosed that a damper that suppresses the left-right movement of the carriage is provided between the bearing box of the carriage and the vehicle body to prevent excessive lateral displacement between the vehicle body and the wheel shaft.

更に、特許文献３には車両用のダンパとして、電磁ダンパを提案している。この電磁ダンパは内部にＤＣ（直流）モータを組み込み、シリンダの直線動またはアームの揺動によりモータを構成するロータまたはステータを回転させ、電磁誘導によってソレノイドに発生した起電力を減衰力に変換する構成とされている。
特開２００２−８７２６２号公報 、図６ 特開２００１−６３５６７号公報 特開２００３−２２７５４３号公報 Furthermore, Patent Document 3 proposes an electromagnetic damper as a damper for a vehicle. This electromagnetic damper incorporates a DC (direct current) motor inside, rotates the rotor or stator constituting the motor by linear movement of the cylinder or swinging of the arm, and converts electromotive force generated in the solenoid by electromagnetic induction into damping force. It is configured.
JP 2002-87262 A, FIG. JP 2001-63567 A JP 2003-227543 A

鉄道車輌には、走行安定性と曲線旋回能が要求される。しかしながら、高速走行での走行安定性と低速走行での急曲線旋回能の両立は困難で、今後とも継続する課題である。   Railway vehicles are required to have running stability and curving ability. However, it is difficult to achieve both the running stability at high speed and the sharp turning ability at low speed.

例えば、特許文献１では車輌連接部の台車をアクチュエータを駆動することで自己操舵せしめることが可能であるが、車輌間のヨーイングに対する減衰効果を発揮することができず、逆にアクチュエータの代わりにダンパを設けると、急曲線通過時に横圧増大を招いてしまう。   For example, in Patent Document 1, it is possible to self-steer a carriage at a vehicle connection portion by driving an actuator, but it cannot exhibit a damping effect against yawing between vehicles, and conversely a damper instead of an actuator. If this is provided, the lateral pressure will increase when passing through a sharp curve.

また、特許文献２に開示されるように台車の左右動を抑制するダンパを設けても、２つの車輌間のヨーイングに対する減衰効果を発揮することはできず、同様に特許文献３では連接車輌については何ら記載されていない。   Further, as disclosed in Patent Document 2, even if a damper that suppresses the left-right movement of the carriage is provided, a damping effect on yawing between the two vehicles cannot be exhibited. Similarly, Patent Document 3 describes a connected vehicle. Is not described at all.

本発明は、車体間のヨーイングを考慮しなければならない連接車輌について、走行安定性と急曲線旋回能の両立を図ることを目的とする。   An object of the present invention is to achieve both running stability and sharp curve turning ability for an articulated vehicle in which yawing between vehicle bodies must be taken into consideration.

斯かる課題を解決するため本発明は、高速走行時または直線走行時は連接部での剛性を高く設定し、低速走行時または曲線走行時は連接部での剛性を低く設定した電磁ダンパを前後の車輌の連接部に配置した。   In order to solve such a problem, the present invention provides a front and rear electromagnetic damper in which the rigidity at the connecting portion is set high during high-speed traveling or straight traveling, and the rigidity at the connecting portion is set low during low-speed traveling or curved traveling. Placed in the connecting part of the vehicle.

また本発明は、前後に連接される２つの車輌の連接箇所に台車を配置した連接車輌であって、前記台車の台車枠またはボルスタと各車輌との間にはそれぞれ電磁ダンパが設けられ、これら電磁ダンパにはＤＣモータなどのモータが組み込まれ、これらモータは電磁誘導により発生した起電力を熱エネルギー（運動減衰力）へ変換するための独立した外部回路と共通した外部回路に切り替え可能に接続された構成とした。   Further, the present invention is an articulated vehicle in which a carriage is arranged at a location where two vehicles are connected in front and rear, and an electromagnetic damper is provided between the carriage frame or bolster of the carriage and each vehicle. A motor such as a DC motor is incorporated in the electromagnetic damper, and these motors can be switched to an external circuit common to an independent external circuit for converting electromotive force generated by electromagnetic induction into thermal energy (kinetic damping force). It was set as the structure made.

上記構成において、各電磁ダンパ内のモータをそれぞれ独立した熱エネルギーへの変換回路に接続することで、各電磁ダンパは個別に減衰機能を発揮する。また各電磁ダンパ内のモータを共通した外部回路に直列に接続した場合、各モータが同一方向に回転するときには起電力が発生せず、反対方向に回転するときには起電力が発生し、電流が流れて熱エネルギーに変換される。   In the above configuration, each electromagnetic damper exhibits a damping function individually by connecting the motor in each electromagnetic damper to an independent thermal energy conversion circuit. When the motors in each electromagnetic damper are connected in series to a common external circuit, no electromotive force is generated when the motors rotate in the same direction, and electromotive force is generated when the motors rotate in the opposite direction. Converted into thermal energy.

上記の回路の切り替えは、例えば、高速走行時または直線走行時に前記各モータを独立した外部回路に接続し、低速走行時または急曲線走行時に前記各モータを共通した外部回路に接続する。   For switching the circuit, for example, the motors are connected to independent external circuits during high-speed traveling or straight-line traveling, and the motors are connected to a common external circuit during low-speed traveling or steep curve traveling.

前記台車としては一軸台車、一輪独立回転台車のいずれでもよく、また電磁ダンパの形態としては直動型ダンパまたは回転型ダンパのいずれでもよい。   The trolley may be either a uniaxial trolley or a single wheel independent rotary trolley, and the electromagnetic damper may be a direct acting damper or a rotary damper.

本発明によれば、２つの車輌の連接箇所に設ける台車の台車枠またはボルスタと、各車輌を電磁ダンパでそれぞれ結合し、これら電磁ダンパ内に組み込まれるモータが接続される回路として、モータが回転せしめられることで発生した起電力を熱エネルギーへ変換するための独立した外部回路と同じく熱エネルギーへ変換するための共通した外部回路に選択的に切り替え可能としたので、必要なときにのみダンパとして作用させることができる。   According to the present invention, a bogie frame or a bolster of a bogie provided at a connection location of two vehicles and each vehicle are coupled by an electromagnetic damper, and the motor rotates as a circuit to which a motor incorporated in these electromagnetic dampers is connected. Since it is possible to selectively switch to a common external circuit for converting heat energy into an independent external circuit for converting the electromotive force generated by being forced into heat energy, as a damper only when necessary Can act.

したがって、高速での直線走行での安定性と急曲線走行時の追従性の両方を同時に満足することができる。   Therefore, it is possible to simultaneously satisfy both the stability in the straight running at high speed and the followability in the sharp curve running.

以下に本発明の実施の形態を添付図面に基づいて説明する。図１は本発明に係る連接車輌としての中間連接三軸車輌の側面図、図２は連接台車と前後の車輌との結合部の拡大側面図、図３は図２の構造を簡略化して示した図である。   Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view of an intermediate articulated triaxial vehicle as an articulated vehicle according to the present invention, FIG. 2 is an enlarged side view of a connecting portion between an articulated carriage and front and rear vehicles, and FIG. 3 shows a simplified structure of FIG. It is a figure.

中間連接三軸車輌は前後の車輌Ａ，Ｂの連接部に１軸台車１を配置し、更に各車輌Ａ，Ｂに１軸台車２，３を配置している。連接部の１軸台車１は車軸１０に左右一対の車輪１１を取付けて輪軸を構成し、また車軸１０の両端は軸箱１２で回転自在に支持され、この軸箱１２上に高剛性の防振ゴム１３を介して台車枠１４が支持され、この台車枠１４上には枕ばね１５を介してボルスタ１６が支持され、ボルスタ１６と前記車輌Ａとがボルスタアンカ１７で連結され、車輌Ａと車輌Ｂとはセンターピン１８で連結されている。   In the intermediate articulated triaxial vehicle, the single-shaft carriage 1 is disposed at the joint portion between the front and rear vehicles A and B, and the single-shaft carriages 2 and 3 are disposed in the vehicles A and B, respectively. The uniaxial cart 1 of the connecting portion is configured by attaching a pair of left and right wheels 11 to an axle 10 to constitute a wheel shaft, and both ends of the axle 10 are rotatably supported by a shaft box 12 on the shaft box 12 with high rigidity. A bogie frame 14 is supported via a vibration rubber 13, and a bolster 16 is supported on the bogie frame 14 via a pillow spring 15. The bolster 16 and the vehicle A are connected by a bolster anchor 17, and the vehicle A The vehicle B is connected with a center pin 18.

また、台車枠１４とボルスタ１６とは、ピン１９を介して回動可能に連結されている。このピン１９の代わりに平行リンク機構を介して台車枠１４とボルスタ１６とを連結してもよい。   Further, the bogie frame 14 and the bolster 16 are connected via a pin 19 so as to be rotatable. The cart frame 14 and the bolster 16 may be connected via a parallel link mechanism instead of the pin 19.

また、前記台車枠１４と前後の車輌Ａ，Ｂとの間にはそれぞれ電磁ダンパ２１，２２が介設されている。また、前記１軸台車２，３の台車枠と各車輌Ａ，Ｂとの間にも電磁ダンパ２３，２４を設けている。このように、台車枠１４はボルスタ１６に対し相対的に回動可能で且つ電磁ダンパ２１，２２で車輌に連結されているので、電磁ダンパの伸縮動による回転方向の減衰力を得て、蛇行動が抑制される。   Electromagnetic dampers 21 and 22 are interposed between the carriage frame 14 and the front and rear vehicles A and B, respectively. Electromagnetic dampers 23 and 24 are also provided between the bogie frames of the single-shaft bogies 2 and 3 and the vehicles A and B, respectively. In this way, the bogie frame 14 is rotatable relative to the bolster 16 and is connected to the vehicle by the electromagnetic dampers 21 and 22. Behavior is suppressed.

前記電磁ダンパ２１〜２４の構造は、図４に示すように、シリンダ３０内にピストン３１が摺動自在に挿着され、シリンダ３０内にはＤＣモータ３２、減速ギヤ３３、ボールネジ３４、ナット３５が組み込まれ、またシリンダ３０とピストン３１の端部には連結部３６，３７が設けられ、電磁ダンパ２１，２２にあっては連結部３６が車輌ＡまたはＢに、連結部３７が台車枠１４にそれぞれ連結されている。   As shown in FIG. 4, the electromagnetic dampers 21 to 24 are structured such that a piston 31 is slidably inserted into a cylinder 30, and a DC motor 32, a reduction gear 33, a ball screw 34, and a nut 35 are inserted into the cylinder 30. Are connected to the end portions of the cylinder 30 and the piston 31. In the electromagnetic dampers 21 and 22, the connecting portion 36 is connected to the vehicle A or B, and the connecting portion 37 is connected to the carriage frame 14. Respectively.

図５〜図９は別実施例を示した図３と同様の図であり、図５に示す実施例にあっては、前後の車輌Ａ，Ｂを通常の連結器２５で連結するとともに、車輌Ａ，Ｂのそれぞれをボルスタ１６によって２点支持している。   5 to 9 are views similar to FIG. 3 showing another embodiment. In the embodiment shown in FIG. 5, the front and rear vehicles A and B are connected by a normal coupler 25, and the vehicle Each of A and B is supported at two points by a bolster 16.

図６に示す実施例にあっては、車輌Ａとボルスタ１６とがボルスタアンカ１７で連結され、ボルスタ１６と台車枠１４との間に電磁ダンパ２１を介設し、車輌Ｂと台車枠１４との間に電磁ダンパ２２を介設している。   In the embodiment shown in FIG. 6, the vehicle A and the bolster 16 are connected by a bolster anchor 17, and an electromagnetic damper 21 is interposed between the bolster 16 and the carriage frame 14, so that the vehicle B and the carriage frame 14 are An electromagnetic damper 22 is interposed between the two.

上記図５および図６に示した実施例は、台車枠１４の上に直接ボルスタ１６を設けたダイレクトマウント方式であるが、図７に示すインダイレクト方式の実施例にあっては、台車枠１４とボルスタ１６との間にボルスタアンカ１７を介設し、ボルスタ１６と車輌Ａとの間に電磁ダンパ２１を設け、ボルスタ１６と車輌Ｂとの間に電磁ダンパ２２を設けている。   The embodiment shown in FIGS. 5 and 6 is a direct mount system in which the bolster 16 is provided directly on the carriage frame 14, but in the embodiment of the indirect system shown in FIG. A bolster anchor 17 is interposed between the bolster 16 and the bolster 16, an electromagnetic damper 21 is provided between the bolster 16 and the vehicle A, and an electromagnetic damper 22 is provided between the bolster 16 and the vehicle B.

図８に示す実施例も図７と同様にインダイレクト方式であり、この実施例では台車枠１４と車輌Ａとの間に電磁ダンパ２１を設け、台車枠１４と車輌Ｂとの間に電磁ダンパ２２を設けている。   The embodiment shown in FIG. 8 is also an indirect system as in FIG. 7. In this embodiment, an electromagnetic damper 21 is provided between the carriage frame 14 and the vehicle A, and the electromagnetic damper is provided between the carriage frame 14 and the vehicle B. 22 is provided.

図９に示す実施例にあっては、台車枠１４と車輌Ａとの間に電磁ダンパ２１を設け、ボルスタ１６と車輌Ｂとの間に電磁ダンパ２２を設けている。   In the embodiment shown in FIG. 9, an electromagnetic damper 21 is provided between the carriage frame 14 and the vehicle A, and an electromagnetic damper 22 is provided between the bolster 16 and the vehicle B.

図１０（ａ）は直線走行時の連接車輌の平面図であり、この状態では電磁ダンパ２１，２２とも伸縮しない。また図１０（ｂ）は曲線走行時の連接車輌の平面図であり、この状態では電磁ダンパ２１，２２とも同時に伸張または圧縮せしめられる。図１０（ｃ）は台車が蛇行動を起こしている状態の平面図であり、この状態では一方の電磁ダンパ２１は伸張し、他方の電磁ダンパは圧縮する。   FIG. 10A is a plan view of the articulated vehicle at the time of straight running. In this state, neither the electromagnetic dampers 21 nor 22 extend or contract. FIG. 10B is a plan view of the articulated vehicle at the time of running on a curve. In this state, the electromagnetic dampers 21 and 22 are simultaneously expanded or compressed. FIG. 10C is a plan view of a state where the carriage is snaked. In this state, one electromagnetic damper 21 expands and the other electromagnetic damper compresses.

次に、上記電磁ダンパ２１，２２の作用について説明する。図１１（ａ）は２つの電磁ダンパ内のモータを独立した熱エネルギーへの変換回路に接続した状態を示す図、（ｂ）は２つの電磁ダンパ内のモータを共通した熱エネルギーへの変換回路に直列に接続した状態を示す図、更に、図１２（ａ）は図１１（ｂ）の接続状態で、２つのモータが互いに同一方向に回転せしめられた場合の回路を説明した図、（ｂ）は図１１（ｂ）の接続状態で、２つのモータが互いに反対方向に回転せしめられた場合の回路を説明した図である。   Next, the operation of the electromagnetic dampers 21 and 22 will be described. FIG. 11A is a diagram illustrating a state in which the motors in the two electromagnetic dampers are connected to an independent thermal energy conversion circuit, and FIG. 11B is a thermal energy conversion circuit in which the motors in the two electromagnetic dampers are shared. FIG. 12 (a) is a diagram illustrating a circuit when two motors are rotated in the same direction in the connection state of FIG. 11 (b). ) Is a diagram illustrating a circuit when two motors are rotated in directions opposite to each other in the connection state of FIG.

図１０の各走行状態に戻って、図１０（ａ）に示した高速で直線走行する場合には、図１１（ａ）に示すように、２つの電磁ダンパ内のモータを独立した熱エネルギーへの変換回路に接続する。このようにすることで、電磁ダンパ２１，２２は独立したダンパとして作用する。   Returning to each traveling state of FIG. 10, when the vehicle travels linearly at the high speed shown in FIG. 10 (a), the motors in the two electromagnetic dampers are converted to independent thermal energy as shown in FIG. 11 (a). Connect to the conversion circuit. By doing in this way, the electromagnetic dampers 21 and 22 act as independent dampers.

一方、低速で急曲線を走行する場合には、図１１（ｂ）に示すように、２つの電磁ダンパ内のモータを共通した熱エネルギーへの変換回路に直列に接続する。そして、この状態で線路に沿って車輌が走行すると図１０（ｂ）に示すように車輌Ａ，Ｂ間にヨーイングが発生する。このとき電磁ダンパ２１，２２は等量だけ圧縮（伸張）するため、モータは同一方向に回転する。２つのモータが同一方向に回転した場合には、図１２（ｂ）に示すように電流は流れないので減衰力は生じない。その結果、ヨーイングに対する抵抗はなく自由にヨーイングが行われる。 On the other hand, when traveling along a sharp curve at a low speed, the motors in the two electromagnetic dampers are connected in series to a common heat energy conversion circuit as shown in FIG. When the vehicle travels along the track in this state, yawing occurs between the vehicles A and B as shown in FIG. At this time, since the electromagnetic dampers 21 and 22 are compressed (expanded) by an equal amount, the motor rotates in the same direction. If two motors are rotated in the same direction, the current as shown in FIG. 12 (b) does not occur damping force does not flow. As a result, there is no resistance to yawing and yawing is performed freely.

また、低速で急曲線を走行する場合には、蛇行動が生じ易い。この場合には、電磁ダンパ２１，２２の一方は圧縮し他方は伸張するため、モータは互いに反対方向に回転する。２つのモータが互いに反対方向に回転した場合には、図１２（ａ）に示すように回路に電流が流れ熱エネルギーに変換され減衰力が生じる。その結果、蛇行動は抑制される。 Further, when traveling on a sharp curve at a low speed, snake behavior is likely to occur. In this case, since one of the electromagnetic dampers 21 and 22 is compressed and the other is expanded, the motors rotate in opposite directions. If two motors are rotated in opposite directions is converted into a current in the circuit flows thermal energy as shown in FIG. 12 (a) damping force. As a result, snake behavior is suppressed.

図示例では、電磁ダンパ２１，２２を一側に配置したが、左右に分けて配置してもよい。この場合は曲線通過時に電磁ダンパ２１，２２の伸縮方向が逆になるので、回路の組み方を変更する必要がある。いずれにしても台車の蛇行時に減衰力を発揮し、車輌間のヨーイングに対しては減衰力が生じないようにすればよい。   In the illustrated example, the electromagnetic dampers 21 and 22 are arranged on one side, but may be arranged separately on the left and right. In this case, since the expansion / contraction directions of the electromagnetic dampers 21 and 22 are reversed when passing through the curve, it is necessary to change how the circuit is assembled. In any case, a damping force may be exerted when the carriage meanders and no damping force is generated against yawing between vehicles.

また、電磁ダンパの配置レイアウトについては、片側２本のみとする配置或いは片側１本づつ（点対称）としてもよい。更に、実施例では電磁ダンパを台車枠または車両との間に直接的または間接的に設けているが、車両と車両との間に設けるようにしてもよい。   Moreover, about the arrangement layout of an electromagnetic damper, it is good also as arrangement | positioning which makes only one side, or one side one side (point symmetry). Furthermore, although the electromagnetic damper is provided directly or indirectly between the bogie frame or the vehicle in the embodiment, it may be provided between the vehicle and the vehicle.
