Description

本発明は、リニアモータによって走行する鉄道用リニアモータ台車及び二次側導体に関するものである。   The present invention relates to a railway linear motor carriage and a secondary side conductor that travel by a linear motor.
鉄道用台車は、従来から回転モータ方式が主として採用されていたが、回転モータ部が大きく車両全体が大型化するため、地下鉄に使用した場合にトンネルの掘削断面積が大きくなり工事費が高くなったり、急勾配や急曲線の線形がとり難かったりするなどの問題があった。
これに対してリニアモータを使用した鉄道車両は、小型化が可能な上に、急勾配や急曲線の線形にも対応が可能であるため、鉄道車両の大きさが建設コストの増減に大きく影響を及ぼす地下鉄などで採用されるようになってきた。
現在、都営地下鉄などで採用されているリニア誘導モータ(LIM)式の鉄道用リニアモータ台車は、台車側に取り付けた一次側コイルbと軌道側に取り付けた二次側導体c(リアクションプレート)の相互作用によって推進力を得るものである。そして、車体及び乗客等の重量は、支持車輪aを介して支持レールeで支持している。
この一次側コイルbと二次側導体cの間隔(以下、ギャップという)は、小さいほど大きな推進力を得ることができ、高いエネルギー効率によって消費電力を節約することができる。しかし、支持レールe又は支持車輪aの摩耗や、乗客の増減による鉄道車両の上下動、曲線部での傾きによってギャップdの大きさは変化するので、一次側コイルbと二次側導体cの接触事故を避けるためにギャップdは広めに設定されている。この結果、エネルギー効率が低下し、消費電力が大きくなるという問題がある。
これに対して、特許文献1には、一次側コイルbと二次側導体cの間に流体を介在させたり、滑車、車輪、ローラー等を介在させたりしてギャップdを一定間隔に保持する方法が開示されている。
特開平7−231515号公報
Conventionally, a rotary motor system has been mainly used for railway carts. However, because the rotary motor section is large and the entire vehicle becomes large, the tunnel excavation cross-sectional area becomes large and the construction cost increases when used in a subway. There are also problems such as steep slopes and steep curve alignment.
On the other hand, railcars using linear motors can be downsized, and can handle steep slopes and sharp curves. It has come to be adopted in the subway etc.
Currently, linear induction motor (LIM) type linear motor carts for railways used in Toei subways, etc., have a primary coil b attached to the cart side and a secondary conductor c (reaction plate) attached to the track side. Propulsion is obtained through interaction. And the weight of a vehicle body, a passenger, etc. is supported by the support rail e through the support wheel a.
The smaller the distance between the primary side coil b and the secondary side conductor c (hereinafter referred to as the gap), the larger the driving force can be obtained, and the power consumption can be saved by high energy efficiency. However, since the size of the gap d changes depending on the wear of the support rail e or the support wheel a, the vertical movement of the railway vehicle due to the increase or decrease of passengers, or the inclination at the curved portion, the primary coil b and the secondary conductor c In order to avoid a contact accident, the gap d is set wider. As a result, there is a problem that energy efficiency is lowered and power consumption is increased.
On the other hand, in Patent Document 1, a fluid is interposed between the primary coil b and the secondary conductor c, or a gap, a wheel, a roller, or the like is interposed to maintain the gap d at a constant interval. A method is disclosed.
JP-A-7-231515
前記した特許文献1のリニアモータ台車においては、リニアモータ(一次側コイルb)を軌道側に設置し、リアクションプレート(二次側導体c)を台車からサスペンション機構で吊り下げる構成を採用している。このように一方の鉛直荷重のすべてを他方に載荷する方法では、押し付け力が推進力の妨げになるため、リアクションプレートのような軽量物を懸架する場合、あるいは小型のリニアモータを懸架する場合でないと採用することはできない。これに対して鉄道用リニアモータ台車に取り付ける一次側コイルbは重量が大きく、特許文献1と同様の構成を採用することはできない。
The above-described linear motor cart of Patent Document 1 employs a configuration in which the linear motor (primary coil b) is installed on the track side and the reaction plate (secondary conductor c) is suspended from the cart by a suspension mechanism. . In this way, with the method of loading all of one vertical load on the other, the pressing force hinders the propulsive force, so it is not a case of hanging a lightweight object such as a reaction plate or a small linear motor. It cannot be adopted. On the other hand, the primary coil b attached to the railway linear motor carriage is heavy and cannot adopt the same configuration as that of Patent Document 1.
上記のような課題を解決するために、本発明の鉄道用リニアモータ台車及び二次側導体は、一次側コイルと二次側導体によって駆動する鉄道用リニアモータ台車であって、枠部材と支持車輪とからなり、前記枠部材又は支持車輪の主軸に懸架装置を介して配置した一次側コイルと、前記一次側コイルの下面よりも下側に突出する間隔保持車輪と、を備え、前記懸架装置を調節することによって前記間隔保持車輪に作用する鉛直荷重の大きさを調節できることを特徴とするものである。ここで、前記間隔保持車輪は前記一次側コイルから前方及び後方に突出させて取り付けることができる。
また、一次側コイルと二次側導体によって駆動する鉄道用リニアモータ台車であって、枠部材と支持車輪とからなり、前記枠部材又は支持車輪の主軸で支持した一次側コイルと、前記一次側コイルの下面よりも下側に突出する間隔保持車輪と、を備え、前記二次側導体に備えた上下可動機構によって前記二次側導体が前記間隔保持車輪に接することを特徴とするものである。ここで、前記鉄道用リニアモータ台車を走行させるために軌道を形成する二次側導体は、作用する鉛直力の大小によって下方又は上方に移動可能に構成することができる。
In order to solve the problems as described above, the railway linear motor carriage and the secondary conductor of the present invention are a railway linear motor carriage driven by a primary coil and a secondary conductor, and are supported by a frame member. A suspension coil including a primary coil disposed on a main shaft of the frame member or the support wheel via a suspension device, and a spacing wheel that protrudes below a lower surface of the primary coil. It is possible to adjust the magnitude of the vertical load acting on the spacing wheel by adjusting the distance. Here, the distance maintaining wheel can be attached by protruding forward and backward from the primary coil.
A railway linear motor carriage driven by a primary side coil and a secondary side conductor, comprising a frame member and a support wheel, and a primary side coil supported by a main shaft of the frame member or the support wheel, and the primary side A distance holding wheel protruding below the lower surface of the coil, and the secondary side conductor is in contact with the distance holding wheel by a vertically movable mechanism provided in the secondary side conductor. . Here, the secondary conductor that forms the track for running the railway linear motor carriage can be configured to be movable downward or upward depending on the magnitude of the acting vertical force.
本発明の鉄道用リニアモータ台車及び二次側導体は、上記した課題を解決するための手段により、次のような効果の少なくとも一つを得ることができる。
<1>一次側コイルと二次側導体の間のギャップを小さな間隔に保持することができる。このため、エネルギー効率に優れ、消費電力を節約することができる。
<2>間隔保持車輪を介在させることで一次側コイルと二次側導体が衝突することがない。
<3>一次側コイルを懸架する懸架装置を調節することによって間隔保持車輪に作用する鉛直荷重の大きさを調節できる。このため、支持車輪や支持レールの摩耗などによって間隔保持車輪の押し付け力が増加した場合でも、押し付け力を所定の大きさに戻して、間隔保持車輪が走行の妨げにならないようにすることができる。
The railway linear motor carriage and the secondary conductor of the present invention can obtain at least one of the following effects by means for solving the above-described problems.
<1> The gap between the primary side coil and the secondary side conductor can be kept at a small interval. For this reason, it is excellent in energy efficiency and can save power consumption.
<2> The primary coil and the secondary conductor do not collide by interposing the spacing wheel.
<3> The magnitude of the vertical load acting on the spacing wheel can be adjusted by adjusting the suspension device for suspending the primary coil. For this reason, even when the pressing force of the spacing wheel is increased due to wear of the supporting wheel or the supporting rail, the pressing force can be returned to a predetermined magnitude so that the spacing wheel does not interfere with traveling. .
以下、図面を参照しながら本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<1>リニアモータ台車
リニアモータ1台車には、鉄道用車体を設置するための枠部材21と、リニアモータ台車1に作用する荷重を支持するための支持車輪22を設ける。
鉄道用のリニアモータ台車1には、一次側コイル3を枠部材21に取り付ける枠装架式台車と、支持車輪22の主軸221に取り付ける主軸装架式台車があり、本発明の構成はいずれにも採用できる。
リアクションプレートと呼ばれる二次側導体4は、並行して敷設された2本の支持レール5の間に配置する。鉄道用リニアモータにおいては、通常、設置費の安価な二次側導体4を、延長距離が長く、使用量が多大になる軌道側に設置する。
<1> Linear Motor Carriage The linear motor single car is provided with a frame member 21 for installing a railway vehicle body and support wheels 22 for supporting a load acting on the linear motor car 1.
The railway linear motor carriage 1 includes a frame-mounted carriage that attaches the primary coil 3 to the frame member 21 and a spindle-mounted carriage that attaches to the spindle 221 of the support wheel 22. Can also be adopted.
The secondary conductor 4 called a reaction plate is disposed between two support rails 5 laid in parallel. In a railway linear motor, the secondary side conductor 4 having a low installation cost is usually installed on the track side where the extension distance is long and the usage amount is large.
<2>懸架装置
懸架装置32は、一次側コイル3を枠部材21又は支持車輪22の主軸221に取り付けるための装置である。
懸架装置32の主要部材は、バネなどの公知のサスペンション機構を使用することができる。一次側コイル3の重量の大部分は、懸架装置32を介して枠部材21又は支持車輪22の主軸221によって支持させる。すなわち、後述する間隔保持車輪31を二次側導体4に接触させるための荷重を残して、それ以外の重量は支持車輪22によって支持させる。
懸架装置32は、間隔保持車輪31に作用する鉛直荷重の大きさを調節できる装置とする。例えば、間隔保持車輪31が二次側導体4に常に接する高さであって、かつ間隔保持車輪31がなくとも二次側導体4に一次側コイル3の下面が接することがない高さか、あるいは接する程度の高さに調節可能な装置とする。すなわち、一次側コイル3を枠部材21や主軸221に上下方向の移動が不変となるように固定すると、支持車輪22や支持レール5が徐々に摩耗するため、二次側導体4と一次側コイル3のギャップは徐々に小さくなる。この結果、間隔保持車輪31に作用する鉛直荷重は大きくなり、大規模な間隔保持車輪の取り付け対策が必要となる。このため、メンテナンス時などに懸架装置32の高さ調節機構によって一次側コイル3の高さを調節し、間隔保持車輪31に最適な鉛直力(押し付け力)を発生させる。ここで、懸架装置32の高さ調節機構は、ネジの回転によって上下動する公知のネジ式の調節機構やバネの増設又は交換式バネなどで構成できる。
なお、懸架装置32が破損した場合であっても、一次側コイル3が落下することがないように、別途、吊り具を設けておくこともできる(図示せず)。
<2> Suspension Device The suspension device 32 is a device for attaching the primary side coil 3 to the frame member 21 or the main shaft 221 of the support wheel 22.
A known suspension mechanism such as a spring can be used as the main member of the suspension device 32. Most of the weight of the primary coil 3 is supported by the frame member 21 or the main shaft 221 of the support wheel 22 via the suspension device 32. That is, a load for bringing the spacing wheel 31 described later into contact with the secondary conductor 4 is left, and the other weights are supported by the support wheels 22.
The suspension device 32 is a device that can adjust the magnitude of the vertical load acting on the spacing wheel 31. For example, the height at which the spacing wheel 31 is always in contact with the secondary conductor 4 and the height at which the lower surface of the primary coil 3 is not in contact with the secondary conductor 4 without the spacing wheel 31, or The device can be adjusted to a height that can be touched. That is, if the primary side coil 3 is fixed to the frame member 21 or the main shaft 221 so that the movement in the vertical direction is not changed, the support wheel 22 and the support rail 5 are gradually worn, so the secondary side conductor 4 and the primary side coil The gap of 3 is gradually reduced. As a result, the vertical load acting on the spacing wheel 31 becomes large, and it is necessary to take measures for mounting the spacing wheel on a large scale. For this reason, the height of the primary coil 3 is adjusted by the height adjustment mechanism of the suspension device 32 at the time of maintenance or the like, and an optimum vertical force (pressing force) is generated on the spacing wheel 31. Here, the height adjustment mechanism of the suspension device 32 can be configured by a known screw type adjustment mechanism that moves up and down by the rotation of a screw, an additional spring, or a replaceable spring.
Even if the suspension device 32 is damaged, a lifting tool can be provided separately (not shown) so that the primary coil 3 does not fall.
<3>間隔保持車輪
間隔保持車輪31は、一次側コイル3の下面よりも下側に突出する自転式移動体である。例えば、車輪やローラーなどが使用できる。間隔保持車輪31を一次側コイル3の下面から突出させることで、一次側コイル3が直接、二次側導体4に接触することがなくなる。
間隔保持車輪31は、例えば一次側コイル3の前後に突出させた枠体に支持させることができる。また、一次側コイル3の下面に取り付けることもできる。また、ギャップの大きさを調節するために、上下方向の高さ調節機構を設けることもできる。
間隔保持車輪31には、走行中も間隔保持車輪31と二次側導体4を常に接触させておくだけの鉛直力を発生させる。この結果、一次側コイル3と二次側導体4のギャップは最小間隔に保持され、エネルギー効率が向上する上に、両者が接触するという危険性がなくなる。
<3> Interval Holding Wheel The interval holding wheel 31 is a rotation-type moving body that protrudes downward from the lower surface of the primary side coil 3. For example, wheels or rollers can be used. By projecting the spacing wheel 31 from the lower surface of the primary coil 3, the primary coil 3 does not directly contact the secondary conductor 4.
The distance maintaining wheel 31 can be supported by, for example, a frame projecting forward and backward of the primary coil 3. It can also be attached to the lower surface of the primary coil 3. Also, a vertical height adjustment mechanism can be provided to adjust the size of the gap.
The distance maintaining wheel 31 generates a vertical force that always keeps the distance maintaining wheel 31 and the secondary conductor 4 in contact during travel. As a result, the gap between the primary side coil 3 and the secondary side conductor 4 is kept at a minimum distance, and the energy efficiency is improved and the risk of contact between the two is eliminated.
<1>枠装架式台車
図1に一次側コイル3を枠部材21で支持する枠装架式台車の斜視図を示す。この場合、枠部材21に懸架装置32の一端を固定し、懸架装置32の他端に一次側コイル3を取り付ける。懸架装置32よって吊り下げられた一次側コイル3の重量の一部を間隔保持車輪31に鉛直荷重として作用させることで、間隔保持車輪31は二次側導体4に接触し続けることができる。乗客の乗降や曲線部での一時的なリニアモータ台車1の上下方向の振幅は、懸架装置32のサスペンション機構で吸収させる。
<1> Frame Mounted Cart FIG. 1 is a perspective view of a frame mounted cart that supports the primary coil 3 with a frame member 21. In this case, one end of the suspension device 32 is fixed to the frame member 21, and the primary coil 3 is attached to the other end of the suspension device 32. By causing a part of the weight of the primary coil 3 suspended by the suspension device 32 to act on the spacing wheel 31 as a vertical load, the spacing wheel 31 can continue to contact the secondary conductor 4. The vertical amplitude of the linear motor carriage 1 at the time of passenger boarding / exiting and the curved portion is absorbed by the suspension mechanism of the suspension device 32.
<2>主軸装架式台車
図2に一次側コイル3を支持車輪22の主軸221で支持する主軸装架式台車の正面図を示す。この場合は、主軸221に懸架装置32の一端を固定し、懸架装置32の他端に一次側コイル3を取り付ける。主軸装架式台車においても上記した枠装架式台車と同様に、一次側コイル3と二次側導体4のギャップは一定の間隔に保持されるため、エネルギー効率の良い状態でリニアモータ台車1を走行させることができる。
<2> Spindle-mounted cart FIG. 2 is a front view of a spindle-mounted cart that supports the primary coil 3 by the main shaft 221 of the support wheel 22. In this case, one end of the suspension device 32 is fixed to the main shaft 221, and the primary coil 3 is attached to the other end of the suspension device 32. Also in the spindle-mounted carriage, the gap between the primary coil 3 and the secondary conductor 4 is maintained at a constant interval, as in the frame-mounted carriage described above, so that the linear motor carriage 1 is in an energy efficient state. Can be run.
実施例2では、図3を参照しながら二次側導体4を上下可動に構成した実施例について説明する。
実施例2では、一次側コイル3は従来と同様に枠部材21や主軸221に固定されていてもよい。従来の鉄道用のリニアモータ台車と相違する構成は、間隔保持車輪31を有する点にある。間隔保持車輪31は、上述した構成と同じものが使用できる。
二次側導体4にはバネなどの上下可動機構41を配置して、二次側導体4に作用する鉛直力の大小によって下方又は上方に移動できるような構成とする。すなわち、二次側導体4を常に間隔保持車輪31に所定の力で押し付ける構成とし、一次側コイル3が二次側導体4から離れる方向に動いたときには上昇させ、反対方向(ギャップが小さくなる方向)に一次側コイル3が動いたときには下降させる。この結果、過度の鉛直力が間隔保持車輪31と二次側導体4の間に働くことがなく、間隔保持車輪31が推進の妨げになることがない。また、二次側導体4が間隔保持車輪31に常に接していれば、一次側コイル3と二次側導体4の最小間隔は保持され、効率よくリニアモータ台車1を推進させることができる。
In Example 2, an example in which the secondary conductor 4 is configured to be movable up and down will be described with reference to FIG.
In the second embodiment, the primary coil 3 may be fixed to the frame member 21 and the main shaft 221 as in the prior art. A configuration different from the conventional linear motor carriage for railroads is that it has a distance maintaining wheel 31. The same thing as the structure mentioned above can be used for the space | interval holding | maintenance wheel 31. FIG.
A vertically movable mechanism 41 such as a spring is disposed on the secondary conductor 4 so that the secondary conductor 4 can move downward or upward depending on the magnitude of the vertical force acting on the secondary conductor 4. That is, the secondary conductor 4 is always pressed against the distance maintaining wheel 31 with a predetermined force, and is raised when the primary coil 3 moves away from the secondary conductor 4, and the opposite direction (the direction in which the gap decreases). ), When the primary coil 3 moves, it is lowered. As a result, an excessive vertical force does not act between the spacing wheel 31 and the secondary conductor 4, and the spacing wheel 31 does not hinder propulsion. Moreover, if the secondary side conductor 4 is always in contact with the distance maintaining wheel 31, the minimum distance between the primary side coil 3 and the secondary side conductor 4 is maintained, and the linear motor carriage 1 can be efficiently driven.
