Description

【0001】
【発明の属する技術分野】
この発明は、車両の連結部を覆う鉄道車両用外幌に係わり、更に詳しくは前後車両間の空間部の全周を覆い、車両の風切り音や車両デッキ部分での騒音の車内への伝達を低減させると共に、操車場における曲率の小さいカ−ブでの大変形に追従可能な耐久性に優れた鉄道車両用外幌に関するものである。
【0002】
【従来の技術】
従来、高速鉄道車両間の空間部を覆う車両用幌は、車両間の内側全周を覆う内幌と、その外側の車両の左右側面のみを覆う外幌から構成されている。
【0003】
前記車両連結部に設けられた内幌は、蛇腹構造に形成され、車内を風雪、ほこり等から保護する役割を果たし、外幌は前後車両の各々の側面に取り付けられた断面U字状のゴム板からなり、車両連結部の美観を呈すると共に、乗客が駅のプラットホームから車両間の空間部の線路に転落するのを防止する役割を果たしてきた。
【0004】
【発明が解決しようとする課題】
然しながら、上記のような車両用幌は、風雪、ほこり等の侵入を防止するために密封性は考慮されているが、騒音に対しては十分な対策が施されておらず、特に外幌は車両の連結部の全周に配設されていないため、風切り音、車輪とレ−ルの摩擦音、レ−ル継ぎ目でのたたき音、車輪の転動音、パンタグラフ擦り音、鉄橋通過時の共鳴音、等が直接内幌を通じてそのまま車両内に入ってくるという問題があった。
【0005】
また、操車場等における曲率半径の小さい軌道を走行する場合に、車両の左右側面に設けた外幌が柔軟に対応できず、外幌同志が接触して寿命を短くする等の問題があった。
【0006】
この発明の目的は、車両内に伝わる車外からの騒音を低減すると共に、耐久性に優れた鉄道車両用外幌を提供することにある。
【0007】
【課題を解決するための手段】
この発明は上記目的を達成するため、前後車両の連結部における車両間の空間部の全周を覆うゴム板からなる環状の外幌であって、前記ゴム板の車両前後方向両端部を外幌の環状内側に突出させて環状の前後端部を形成し、該環状の前後端部を車両に取り付けるように構成するとともに、前記ゴム板の車両前後方向中央部近傍に、内側に湾曲させた断面U字状の変形・追従部を形成し、前記外幌の断面において前記変形・追従部を挟んで車両前後方向に対向する外幌本体のゴム板どうしが車両前後方向に同一直線状にある場合に、前記変形・追従部の断面U字状の開口部が隙間をあけて開口状態になるようにし、前記外幌の断面において変形・追従部の付け根部分の外幌内側近傍と、前後車両の外幌を取り付けている位置よりも外幌内側方向となる位置とを直線状に連結する支持梁ゴムを、外幌の環状の全周にわたって或いは環状の周上の一部に設けたことを要旨とするものである。
【0008】
ここで、外幌の生産性と取り付けの作業性を考慮して前記変形・追従部を外幌本体のゴム板と着脱可能に構成されたU字状の断面を有するゴム板とする
【0009】
また、外幌の剛性を保つため、前記外幌の断面において変形・追従部の付け根部分の外幌内側近傍と、前後車両の外幌を取り付けている位置よりも外幌内側方向となる位置とを直線状に連結する支持梁ゴムを外幌の環状の全周にわたって或いは環状の周上の一部に設けることにより補強し、この支持梁ゴムを取り外し可能なゴム板にする
【0010】
ここで、前記変形・追従部及び外幌本体のゴム板の内部に、補強層を埋設することもでき、前記支持梁ゴムの内部に補強層を埋設することもできる。このような構成により、風切り音、車輪とレ−ルの摩擦音、レ−ル継ぎ目でのたたき音、車輪の転動音、パンタグラフ擦り音、鉄橋通過時の共鳴音、等の車両の外部からの騒音を一次的に遮断して、内幌を通じて車両内に伝わる騒音を低減することが出来るものである。
【0011】
更に、操車場等における曲率半径の小さい軌道を走行する場合には、変形・追従部を中心にしてゴム板が変形することにより外幌同志が接触することによって損傷することがなく耐久性を向上させることが可能である。
【0012】
【発明の実施の形態】
以下、添付図面に基づき、この発明の実施形態を説明する。なお、各図において、同一の構成要素には同一の符号を付し、重複した説明を省略する。
【0013】
図1は外幌が車両に取り付けられた状態を説明するための一部斜図で、前方車両の外形線を点線で表示してある。
【0014】
図1に示すように車両1の連結部は、車両間の空間部の全周を覆う環状のゴム板からなる外幌2が設けられている。
【0015】
図2は、図1のA−A矢視断面図で、外幌2を構成するゴム板は、その長手方向中央部近傍が内側に向かって変形・追従部3が形成してあり、環状のゴム板の前後端部2a,2bは、それぞれ前方車両後端部4と後方車両前端部5とに取り付けられ、変形・追従部3は、車両走行時の蛇行を吸収する作用をなすものである。
【0016】
図3は、変形・追従部3を外幌2本体のゴム板と着脱可能に構成した図2に相当する断面図で、断面U字状に形成したゴム板から成る変形・追従部6を外幌2本体のゴム板の端末部に取り付けた状態を示している。このように変形・追従部6を、ボルト等の締結部材を介して着脱可能に構成することにより外幌2の生産性と車両1への取り付けに要する作業性を向上させる。
【0017】
また図4は、外幌2の車両外側への異常変形を防止するための図2に相当する断面図で、変形・追従部3の付け根部分の内側近傍と前後車両の内側とを支持梁ゴム7で一体的に連結して補強した場合を示している。支持梁ゴム7による補強は環状体の全周にわたるものでも、周上の一部に施される場合でも良い。
【0018】

なお、その他の構成及び作用は上記図2〜図4に示した外幌と同様なので同一符号を付して説明は省略する。
【0020】
上記外幌本体のゴム板及び着脱可能に構成した変形・追従部3または支持梁ゴム7を構成するゴム板は、EPDM、CR、IR、NBR、BR、SBR、NR等の汎用ゴムを加硫成形して得るが、必要に応じて剛性、復元性を増すために補強層としてナイロン、アラミド、PET等の繊維からなる織布にこれらのゴムを被覆して使用する。
【0021】
図6及び図7は、この発明の外幌2を取り付けた車両1が操作場等における曲率半径の小さい軌道を走行する場合の外幌2の動きを説明するための図2に相当する断面図で、図6は軌道の外周側の外幌2の動きを示し、図7は軌道の内周側の外幌2の動きをそれぞれ示している。
【0022】
軌道の外周側では、図6に示すように変形・追従部3が開口し、軌道の内周側では、図7に示すように変形・追従部3が閉口すると共に、外幌本体のゴム板が変形して蛇行を吸収ために、外幌2自体には無理な力が働らかず、前後車両の連結部における車両間の空間部の全周を覆って、車外騒音をそのまま内幌を通じて車内に伝達するのを防ぐことが出来る。
【0023】
【発明の効果】
この発明は、上記のように前後車両の連結部における車両間の空間部の全周を覆うゴム板からなる環状の外幌であって、前記ゴム板の車両前後方向両端部を外幌の環状内側に突出させて環状の前後端部を形成し、該環状の前後端部を車両に取り付けるように構成するとともに、前記ゴム板の車両前後方向中央部近傍に、内側に湾曲させた断面U字状の変形・追従部を形成し、前記外幌の断面において前記変形・追従部を挟んで車両前後方向に対向する外幌本体のゴム板どうしが車両前後方向に同一直線状にある場合に、前記変形・追従部の断面U字状の開口部が隙間をあけて開口状態になるようにし、前記外幌の断面において変形・追従部の付け根部分の外幌内側近傍と、前後車両の外幌を取り付けている位置よりも外幌内側方向となる位置とを直線状に連結する支持梁ゴムを、外幌の環状の全周にわたって或いは環状の周上の一部に設けたので、車両間の空間部の全周を環状の外幌で覆い、車外からの騒音を一旦外幌が遮断するため、車外騒音をそのまま内幌を通じて車内に伝達するのを防ぎ、車内の騒音の低減に効果がある。
【0024】
また、操作場等における曲率半径の小さい軌道を走行する場合にあっては、変形・追従部が開口または閉口すると共に外幌本体のゴム板が変形するため、外幌に無理な力が働くことがなく外幌の耐久性が保証される。
【0025】
更に、変形・追従部および支持梁ゴムを着脱可能に構成することにより、外幌の生産性と車両への取り付けに要する作業性を向上させることが出来る。
