Description

【0001】
【発明の属する技術分野】
本発明は、軽量化を図ることができる鉄道車両用台車に関するものである。
【000
【従来の技術】
在採用されている高速鉄道車両用ボルスタレス台車には、台車の蛇行動を防止するために、その大部分にヨーダンパを取り付けている。加えて、車体のローリングを防止するためのアンチローリング装置を取り付ける場合は、車体の上下、前後、左右動を許容しつつ、ローリングに対してのみ剛性を持たせる必要があることから、ヨーダンパとは別に独立して存在する。ヨーダンパの取り付け方法として、例えば特開昭61−241258号では、図3のように、台車11の回転中心から所定の距離を隔てた位置に、車軸14とほぼ平行にかつ台車11に対して回転が自在なように、枕木方向に設けたねじり棒8と、その両端にレール方向に向けて配したヨーダンパ9を、リンク10を介して結合することで、台車11の振動がヨーダンパ9を介して車体12に伝達されるのを防止するものが開示されている。
【000
しかしながら、特開昭61−241258号で開示されたものでは、ヨーダンパを介して伝達される振動成分を減じることはできるものの、ねじり棒やリンク機構など、部品点数が大幅に増えて、台車の重量を増加させる原因になる。
【000
【発明が解決しようとする課題】
以上説明したように、従来の鉄道車両用台車では、ヨーダンパに加えてアンチローリング装置を設置した場合には、台車の重量が増加するという問題があった。
【000
本発明は、上記した問題点に鑑みてなされたものであり、ヨーダンパに加えてアンチローリング装置を備えた場合においても、重量増加を可及的に抑制することができる鉄道車両用台車を提供することを目的としている。
【0006】
【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、本発明の鉄道車両用台車は、レール方向に水平に配置した2個の各ヨーダンパの一方端を、台車の回転中心から所定の距離を隔てた位置に、車軸とほぼ平行にかつ台車に対して回転が自在なように配置したねじり棒の、左右両端に各々固定すると共に、各ヨーダンパの他方端は、車体から垂下されたダンパ受け部材に枢支連結するようにしたのである。そして、このようにすることで、ヨーダンパに加えてアンチローリング装置を備えた場合においても、可及的に重量増加を抑制することができる。
【0007】
【発明の実施の形態】
本発明の鉄道車両用台車は、レール方向に水平に配置した2個の各ヨーダンパの一方端を、台車の回転中心から所定の距離を隔てた位置に、車軸とほぼ平行にかつ台車に対して回転が自在なように配置したねじり棒の、左右両端に各々固定すると共に、これらの各ヨーダンパの他方端は、車体から垂下されたヨーダンパ受け部材に枢支連結したものであり、必要に応じて、ヨーダンパを構成するシリンダと、ピストンを一自由度で拘束する。
【0008
本発明の鉄道車両用台車は、上記したように構成したので、台車に、ヨーダンパに加えてアンチローリング装置を備えた場合においても、台車の重量増加を可及的に抑制することができる。
【0009
【実施例】
以下、本発明の鉄道車両用台車を図1〜図に示す実施例に基づいて説明する。
1(a)は本発明の鉄道車両用台車の全体概略を説明する斜視図、(b)は車体を加えた(a)の部分図、(c)は上下振動時におけるねじり棒とヨーダンパの状態を説明する図、(d)はローリング時におけるねじり棒とヨーダンパの状態を説明する図、図は本発明の鉄道車両用台車の他の態様の要部概略を説明する図である。
【0010】
図1及び図2において、22はレールと同方向に水平に配置したヨーダンパ、例えばオイルダンパであり、例えば前後に配置された2本の横梁1によって固定された側梁2の外側にそれぞれ一個ずつ、計2個配置されている。そして、本発明の鉄道車両用台車では、これらヨーダンパ22の一方端を、台車11に回転が自在なように支持させたねじり棒8の左右の両端に固定すると共に、他方端は、車体12から垂下されたダンパ受け部材23に、例えばゴムブッシュ24を介して枢支連結させたものである。
【001
すなわち、本発明の鉄道車両用台車では、水平に取付けられるアンチローリング装置の取付け腕としてヨーダンパ22を採用し、取付け腕すなわちヨーダンパ22と車体12間に介設するうでを、車体12から垂下状に設けたダンパ受け部材23として、車体12に剛に結合することで、アンチローリング装置にヨーダンパの機能を付加している。
【0012
従って、車体12と台車11が上下方向に相対移動する場合には、図(c)に示すように、左右のヨーダンパ22とねじり棒8が一体として回転するので、上下方向の動きを拘束することはない。一方、車体12がローリングした場合には、図(d)に示すように、ねじり棒8がねじられてねじり反力が発生し、アンチローリング装置として作用する。
【0013
なお、前後方向の動きは、ゴムブッシュ24とヨーダンパ22とで許容され、また、左右方向の動きは、ねじり棒8が軸方向に自由に移動できるように支承されていることから、このねじり棒8の軸方向移動によって許容されることになる。また、ヨーダンパ22の機能については、取付け腕を兼ねたヨーダンパ22がほぼ水平に取付けてあるので、通常のヨーダンパ22として作用することは言うまでもない。
【0014
本発明の鉄道車両用台車では、上記した構成を採用することで、アンチローリング装置にヨーダンパの機能を付加できるので、台車11に、ヨーダンパに加えてアンチローリング装置を備えた場合においても、台車11の重量増加を可及的に抑制することができる。
【0015
また、上記した実施例では、その構成上ヨーダンパ22のピストン22bとシリンダ22aの接触部に曲げモーメントが作用することになるが、これを避けるためには、図2に示したように、シリンダ22aと車体12の間を、例えばリンク25で連結して、ヨーダンパ22を構成するシリンダ22aと、ピストン22bを一自由度で拘束するようにすれば良い。このようにすれば、台車11と車体12間でローリングが生じた場合には、ねじり棒8にトルクを加える曲げモーメントを、シリンダ22aとリンク25が負担することになるので、車体側のダンパ受け部材23はピストンロッド22cを介して前後荷重のみを負担することになる。
【0016
【発明の効果】
以上説明したように、本発明の鉄道車両用台車は、上記したように構成したので、台車に、ヨーダンパに加えてアンチローリング装置を備えた場合においても、台車の重量増加を可及的に抑制することができる。
