Abstract
Description
また、直流方式の場合において、正電車線は走行路側に取り付けられ、負電車線は案内レールを利用している構造もあるが、ゴムタイヤ式新交通システムでは正電車線及び負電車線を走行路側に並べて設置するか、左右の走行路側に分けて設ける構造が一般的である。この場合、案内ガイドは、案内輪が大きいことから、走行路面より下方に位置するため、電車線も走行路面より下方に位置している。また、案内レールと電車線は、絶縁離隔を確保するため、十分離れた位置に別々に設けられている。このように、センターガイド方式では、電車線が走行路面より下に位置し、案内レールから離れた位置に設けてあるため、走行路面下に軌道スペースが必要となる。そのため、軌道を構成するための断面積が大きくなり、トンネル部等がある場合には膨大なコストがかかってしまう。
すなわち、特許文献1は、H型鋼で構成される案内ガイド内に電車線が配置される構成である。そのため、正電車線と負電車線との絶縁距離が短くなり、短絡が生じ易いという問題がある。
また、保護部材を電車線の幅方向両側に設ける場合には、電車線と車両各部との絶縁離隔を適正に確保することができる。そして、集電装置の集電シューが上から下へ押し付けられる構造となるので、自重による作用とも相まって電車線に対する追従性が良好となり、離線しにくくなる。
さらに、軌道内は車両故障時の避難通路にもなり得るが、避難時において電源をOFFにした場合であっても保護部材により電車線が保護されているので、間違って電車線(充電部)に電源が入っても安全である。
また、電車線(充電部)に保護部材を設けることで、電車線の絶縁離隔範囲を小さくして必要な絶縁距離が確保できるとともに、電車線が保護される。そのため、電車線どうしの短絡や、電車線に対する車両や他構造部材との短絡を防止することができる。
図1に示すように、本発明の第1の実施形態に係る交通システム1は、センターガイド方式を採用している。交通システム1は、軌道系車両10と、軌道系車両10に設けられた一対の案内輪23(23A、23B)を転動させることで所定の走行経路に沿うように案内するための案内軌条3Aとを備えている。
ここで、図1及び図2において、紙面左右方向を車幅方向Xといい、紙面に対して直交する方向を前後方向Zといい、紙面上下方向を上下方向Yという。
ここで、走行輪12が走行する走行路面Rは、全面にわたって平坦面である。そして、走行路面R上の幅方向X中央の位置、すなわち幅方向の両側の走行輪12、12どうしの間には、案内軌条3Aが走行経路の前後方向Zに沿って敷設されている。なお、案内軌条3Aは、本発明の第一の実施形態では幅方向X中央の位置としているが、この位置であることに制限されることはなく、左右の走行輪12、12の間であれば中央から左右いずれかにずれた位置であってもかまわない。
正集電装置4A及び負集電装置4Bは、面方向が幅方向Xに直交する方向に向けられた取付板41をそれぞれ備える。それぞれの取付板41には案内装置2の案内枠21に固定される装置支持部42と、ばね付リンク機構47の付勢力により、電車線32に押付けられて接触給電する集電シュー43とを備えている。なお、集電シュー43は、電車線32のエンドアプローチ等において集電シュー43の首振りに対応するため、ピン部44を介して取付板41に取り付けられている。
装置支持部42は、案内装置2の案内枠21の側面21aに固定するための第2碍子46と絶縁部材45と、取付板41に中央向きの付勢力を与えるための前記ばね付リンク機構47とから構成されている。
図2に示すように、本実施形態では、ガイドレール31の案内溝31aに案内輪23A、23Bが配置され、ガイドレール31の幅方向の両側に第1碍子33を介して電車線32A、32Bが設けられ、正電車線32Aと負電車線32Bとがガイドレール31を挟んで両側に設けられる構成を備える。そのため、正電車線32Aと負電車線32Bとの離間距離を大きくすることができる。その結果、従来のガイドレールの案内溝内に正電車線及び負電車線を配置する場合に比べて絶縁距離を大きく確保することができ、層間短絡を防止することができる。
さらに、軌道内は車両故障時の避難通路になり得るが、避難時において電源をOFFにした場合であっても絶縁板34により電車線32A、32Bが保護されているので、間違って電車線32A、32Bに電源が入っても安全である。
また、電車線32に絶縁板34が設けられることで、電車線32の絶縁離隔範囲Tを小さくして必要な絶縁距離が確保できる。さらに、電車線32が保護されるため、電車線32A、32Bどうしの短絡や、電車線32に対する軌道系車両10や他構造部材との短絡を防止することができる。
図4に示すように、本発明の第2の実施形態による軌道系車両の案内軌条3Bは、ガイドレール31の両側面に電車線32A、32Bを支持するためのブラケット36が設けられ、このブラケット36に第1碍子33が垂直に取り付けられ、その第1碍子33の電車線支持端33bに電車線32A、32Bが支持される構成を備える。
ここで、ガイドレール31、第1碍子33、正電車線32A、負電車線32Bの構成は、上述した第1の実施形態と同様であるので、ここでは詳しい説明を省略する。
なお、図4は、集電装置を省略するとともに、案内装置の案内輪23(23A、23B)のみを記載した図である。
また、絶縁材37A、37Bが電車線32A,32Bの幅方向の両側に設けられているので、これら電車線32A、32Bと車両各部との絶縁離隔を適正に確保することができる。そして、図示しない集電装置の集電シューは上から下へ押し付けられる構造を有するので、自重による作用とも相まって電車線32A,32Bに対する追従性が向上し、離線しにくくなる。
次に、図5に示す本発明の第3の実施形態に係る軌道系車両の案内軌条3Cは、正電車線32A及び負電車線32Bのそれぞれの支持部が絶縁板(保護部材)を兼ねる構成を備える。
すなわち、案内軌条3Cは、ガイドレール31(軌条本体)の幅方向Xで両外側面31dに沿って電車線32を収容可能な絶縁材から構成される収容凹部38(支持部、保護部材)が設けられている。この収容凹部38は、断面視でU字型を形成し、開口部38a側が幅方向の外側に向けて配置されている。そして、収容凹部38は、ガイドレール31の外側面31dの上端31cと外側面31dの下方との上下二箇所から幅方向の外側に向けて突出させた一対のブラケット39A、39B間に嵌合された状態で固定されている。
また、収容凹部38が電車線32とガイドレール31とを支持する支持部を構成するとともに、保護部材としても機能する。そのため、別体の保護部材を設ける必要がなくなるので、部品数を削減することができ、コストの低減を図ることができる。
次に、図7に示す第1変形例に係る案内軌条3Dでは、上述した第3の実施形態において電車線32を収容した収容凹部38を取付ける構造が異なる。つまり、本変形例では、第3の実施形態の上側のブラケット39A(図5参照)を省略するとともに、収容凹部38が下側のブラケット39B上に第3碍子50、50を介して固定されている。この場合の収容凹部38は、第3碍子50用の係止部38dを有し、その他の構成は第3の実施の形態と同様である。
次に、図8に示す第2変形例に係る案内軌条3Eでは、上述した第3の実施形態において電車線32を収容した収容凹部38の開口部38aが上に向いている。つまり、収容凹部38の互いに対向して配置される二面が幅方向Xに向き合う側面38c、38cを構成し、内部の電車線32のシュー接触面32bが上向きで収容凹部38の開口部38a側に位置している。そして、このシュー接触面32bは、開口部38aよりも低く位置している。
次に、図9に示す第3変形例に係る案内軌条3Fでは、上述した第2変形例の電車線32が収容された収容凹部38が第1変形例に係る下側のブラケット39B上に第3碍子50、50を介して固定されている。
例えば、案内輪23A、23Bの形状、大きさ、電車線32A、32Bの位置、集電装置4の構成、各碍子の種類、大きさ、構成は、適宜設定することができる。
また、絶縁体34、37の寸法、位置(電車線32との離間)、部材、取り付け位置などの構成についても、電車線32の位置、形状、絶縁離隔範囲Tなどの条件に応じて任意に設定することができる。
