Description

【0001】
【発明の属する技術分野】
本発明は、牽引リンクの取付け作業が容易で、牽引リンクと台車枠間で異常止めを構成することが可能な鉄道車両用ボルスタレス台車の牽引装置に関するものである。
【0002】
【従来の技術】
従来のボルスタレス台車における牽引装置は、例えば図3に示したように、車体1の下部に取付けられた牽引枠2と台車枠3とを牽引リンク4を介して連結した構成で、この牽引リンク4と、牽引枠2及び台車枠3との結合は、台車の前後方向に向けたボルト5により行い、このボルト5を介して前後力を伝達するものであった。
【0003】
この図3に示したような構成の牽引装置においては、車体1が異常上昇した場合には、図4に示したように、牽引リンク4の牽引枠2取付け部側の端部が台車枠3に当たるので、これらの間で異常上昇止めを構成することができる。
【0004】
しかしながら、図3に示した構成の牽引装置では、ボルトを介して台車と車体間に作用する前後力を伝達する構成であるので、この前後力に耐え得るだけの断面、サイズを有するボルトを使用する必要があり、また、ボルトのサイズに合わせて締結トルクも大きくなるので、作業性が悪くなるという問題があった。
【0005】
そこで、図5に示すように、牽引枠2と台車枠3における牽引リンク4との取付け部分を、勾配を持った凹形状部2a,3aとなし、牽引リンク4両端における軸部4aを、前記凹形状部2a,3aに嵌り込む形状とすることで、前後力をボルトを介さずに凹形状部2a,3aと軸部4aの間で伝達するものが実開平2−27970号で提案されている。
【0006】
この実開平2−27970号で提案された牽引装置によれば、前後力をボルトを介さずに凹形状部と軸部の間で伝達するので、牽引リンクと、牽引枠及び台車枠との結合に使用するボルトのサイズを小型化でき、作業性を改善することができる。
【0007】
【発明が解決しようとする課題】
しかしながら、実開平2−27970号で提案された牽引装置では、牽引枠に形成した凹形状部が邪魔になって、図3に示した牽引装置では可能であった、牽引リンクにおける牽引枠取付部側の端部と、台車枠との間で、異常上昇止めを構成することができない。
【0008】
従って、実開平2−27970号で提案された牽引装置において異常上昇止めを形成する場合には、図5に示したように、例えば牽引枠2を上下に二分割構成し、下部の牽引枠2bと台車枠3との間で異常上昇止めを構成するなどの必要があり、部品点数や作業工数の増加を招くという問題がある。
【0009】
本発明は、上記した問題点に鑑みてなされたものであり、牽引リンクを取付けるボルトのサイズを小型化できて牽引リンクの取付け作業が容易に行えると共に、牽引リンクと台車枠との間で異常止めを構成することが可能な鉄道車両用ボルスタレス台車の牽引装置を提供することを目的としている。
【0010】
【課題を解決するための手段】
上記した目的を達成するために、本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、牽引枠と台車枠における牽引リンクとの嵌り込む形状の取付け部分を、両側面間の間隔が奥部に行くほど小さくなるような勾配を側面に有する凹形状部となし、牽引リンク両端における軸部を、前記凹形状部に下方から嵌り込む形状となして、下方から上方に向けたボルトで締結と共に、前記牽引リンクにおける牽引枠側取付部を牽引リンクの軸方向に延長し、この延長部分と台車枠とで異常上昇止めを構成することとしている。そして、このようにすることで、牽引リンクを取付けるボルトのサイズを小型化できると共に、牽引リンクと台車枠との間で異常止めを構成することが可能になる。
【0011】
【発明の実施の形態】
本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、
車体に取付けた牽引枠と台車枠とを連結する牽引リンクによって台車と車体間に作用する前後力を伝える鉄道車両用ボルスタレス台車の牽引装置において、
牽引枠と台車枠における牽引リンクとの嵌り込む形状の取付け部分を、両側面間の間隔が奥部に行くほど小さくなるような勾配を側面に有する凹形状部となし、
牽引リンク両端における軸部を、前記凹形状部に下方から嵌り込む形状となして、下方から上方に向けたボルトで締結と共に、
前記牽引リンクにおける牽引枠側取付部を牽引リンクの軸方向に延長し、この延長部分と台車枠とで異常上昇止めを構成するものである。
【0012】
本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、牽引枠と台車枠における牽引リンクとの嵌り込む形状の取付け部分を、両側面間の間隔が奥部に行くほど小さくなるような勾配を側面に有する凹形状部となすと共に、牽引リンク両端における軸部を、前記凹形状部に下方から嵌り込む形状として、台車と車体間に作用する前後力をボルトを介さずに凹形状部と軸部の間で伝達するようにしたので、牽引リンクと、牽引枠及び台車枠との結合に使用するボルトのサイズを小型化でき、作業性を改善することができる。
【0013】
また、本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、牽引リンクにおける牽引枠側取付部を牽引リンクの軸方向に延長し、この延長部分と台車枠とで異常上昇止めを構成するので、異常上昇止めを構成するための部品点数や作業工数の増加を招くことがない。
【0014】
【実施例】
以下、本発明を図1及び図2に示す実施例に基づいて説明する。
図1は本発明に係る鉄道車両用ボルスタレス台車の牽引装置の一実施例を示す側面図、図2は図1において車体が異常上昇し、台車枠と牽引リンクがストッパ当たりをした状態を示す側面図である。
【0015】
図1及び図2において、11は本発明に係る鉄道車両用ボルスタレス台車の牽引装置であり、車体1に取付けた牽引枠2と台車枠3とを、例えば両端に弾性体13を備えた牽引リンク12によって連結し、この牽引リンク12によって台車枠3から車体1に前後力を伝える構成である。
【0016】
そして、本発明に係る鉄道車両用ボルスタレス台車の牽引装置11にあっては、牽引枠2と台車枠3における牽引リンク12との取付け部分を、勾配を持った凹形状部2a,3aとなすと共に、牽引リンク12の両端に備えた弾性体13に形成した軸部13aを、前記凹形状部2a,3aに嵌り込む形状となしている。
【0017】
14は牽引枠2の凹形状部2aや台車枠3の凹形状部3aに軸部13aを取付けるボルトで、本発明に係る鉄道車両用ボルスタレス台車の牽引装置11にあっては、下方から上方に向けて締結し、このボルト14によって台車枠3と車体1間の前後力を伝えるものではない。
【0018】
すなわち、本発明に係る鉄道車両用ボルスタレス台車の牽引装置11にあっては、車体1と台車枠3間に作用する前後力は、ボルト14を介さずに凹形状部2a,3aと軸部13aの間で伝達するようにしたので、牽引リンク12と、牽引枠2及び台車枠3との結合に使用するボルト14のサイズを小型化でき、作業性を改善することができる。
【0019】
12は牽引リンク12における牽引枠側取付部を軸方向に延長した延長部であり、この延長部12と台車枠3とで異常上昇止めを構成している。従って、車体1が異常上昇した場合には、図2に示したように、牽引リンク12の延長部12aが台車枠3に接触して、ストッパ当たりすることになる。
【0020】
すなわち、本発明に係る鉄道車両用ボルスタレス台車の牽引装置11にあっては、牽引リンク12の延長部12と台車枠3とで異常上昇止めを構成しているので、異常上昇止めを構成するための部品点数や作業工数の増加を招くことがない。
【0021】
本実施例では、牽引リンク12の両端に弾性体13を備え、この弾性体13に軸部13aを形成したものを示したが、弾性体13は必ずしも必須のものではない。従って、弾性体13を備えないものでは、牽引リンク12の両端部に軸部を形成する。
【0022】
【発明の効果】
以上説明したように、本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、牽引枠と台車枠における牽引リンクとの嵌り込む形状の取付け部分両側面間の間隔が奥部に行くほど小さくなるような勾配を側面に有する凹形状部となし、この凹形状部に牽引リンク両端における軸部を下方から嵌り込ませ、車体と台車枠間に作用する前後力を凹形状部と軸部の間で伝達するようにしたので、牽引リンクと、牽引枠及び台車枠との結合に使用するボルトのサイズを小型化でき、作業性を改善することができる。
【0023】
また、本発明に係る鉄道車両用ボルスタレス台車の牽引装置は、牽引リンクにおける牽引枠側取付部を牽引リンクの軸方向に延長し、この延長部分と台車枠とで異常上昇止めを構成するようにしたので、異常上昇止めを構成するための部品点数や作業工数の増加を招くことがない。
