Description

【0001】
【発明の属する技術分野】
本発明は、車両が曲線軌道を乗り心地を損なわずに高速走行するために、車体を傾斜させる鉄道車両の車体傾斜装置に関する。
【0002】
【従来の技術】
車体傾斜装置として、車体重心よりも高い位置に振子中心を置き、曲線軌道を走行する際に車体重心に作用する遠心力を利用して、振子中心回りに車体を回転させて車体重心を外軌側に移動させる自然振子式がある。この自然振子式としては、例えば、図9に示されるように、車体1下部の振子梁2と台車枠3との間に左右一対の円柱状のコロ4,4を配設し、このコロ4,4上に振子梁2の円弧面を転動させる構成のものや、実用新案登録第2556312号公報に示されるように、振子運動の軌跡に沿って形成したガイドレールと、該ガイドレールの振子方向のみの動きを許容するガイド部を備えたガイドブロックと、ガイドレール及びガイド部にそれぞれ設けたボール転動溝間に配設した多数の転動ボールとで構成したもの等がある。また、この動きを補助するために、図10に示されるように、振子梁2と台車枠3との間に空気圧シリンダ5を配設し、該空気圧シリンダ5の伸縮により車体傾斜を行うものがある。
【0003】
【発明が解決しようとする課題】
しかし、上述の構造でさらに高速で曲線軌道を走行させようとすると、振子中心を車体重心の近くに位置させねばならないが、振子中心を低くすると、車体重心に作用する遠心力は車体傾斜を行いたい方向の大きなモーメントとならないため、空気圧シリンダは形状的に大きくなってスペース面での制約を受ける。そこで油圧シリンダを採用すると、油圧ポンプや油圧配管を含めた油圧システムと油圧制御の電気システムを構築するため、重量やコスト面で不利であり、また、油圧システムは、油圧が上昇するまでのタイムラグがあるので、車体傾斜制御の遅れが懸念される。さらに、作動油のコンタミネーション(ゴミ混入)に注意する必要があり、メンテナンス面で大変煩わしい。
【0004】
そこで本発明は、電気システムで作動し、油圧システムに比較して、重量が軽くてコストも安く、正確な位置制御及び応答の早い制御が可能で、メンテナンスも容易な鉄道車両の車体傾斜装置を提供することを目的としている。
【0005】
【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、本発明は、車体下部の振子梁と台車枠の横梁との間に配設したボールネジシリンダにより車体を傾斜させる鉄道車両の車体傾斜装置において、前記ボールネジシリンダは、ナット部材と該ナット部材に螺合するボルト部材とで構成され、前記振子梁の前面又は後面のいずれか一面に配置され、前記ナット部材を、前記台車枠の横梁に上下方向に回動可能に設けるとともに、前記ボルト部材を、前記振子梁の前面又は後面のいずれか一面に上下方向に回動可能に設けられている筒部材に回転可能に支持し、前記筒部材は、一対のスラスト軸受を介して前記ボルト部材の頭部側軸部を支持し、該ボルト部材の頭部側軸部のスラスト軸受間にはベベルギアが固設され、該ベベルギアには、前記頭部側軸部に直交して車体前後方向に設けられた入力軸のベベルギアが噛み合っており、前記振子梁の前記ボールネジシリンダの取付側面とは反対側の面に、該ボールネジシリンダの電動駆動源と変速装置とを設け、該変速装置は、前記筒部材の取付位置に対応して設けて、前記変速装置の出力軸を中間スプライン付ユニバーサルジョイントを介して前記筒部材の入力軸のベベルギアに接続され、前記電動駆動源の出力軸は、入出力方向変換装置に接続され、該入出力方向変換装置と前記変速装置とは、両端にユニバーサルジョイントを備えたシャフトで接続され、該シャフトの先端を前記変速装置から突出させて、故障時の手動アクセス部としたことを特徴としている。
【0006】
【発明の実施の形態】
以下、本発明を、図1乃至図8に示す実施形態例に基づいて、さらに詳細に説明する。図1乃至図6は本発明の第1実施形態例を示すもので、本実施形態例の振子装置は、車体10下部の振子梁11の前面及び後面にそれぞれ配設される左右一対のガイドレール12,12と、該ガイドレール12,12に対応して台車枠13に固設される左右一対のガイドブロック14,14とで構成されている。ガイドレール12,12は、振子運動の軌跡に沿って形成され、ガイドブロック14,14は、ガイドレール12,12の振子方向のみの動きを許容するガイド部を備え、ガイドレール12,12及びガイド部にそれぞれ設けたボール転動溝間に多数の転動ボールを配設している。
【0007】
振子梁11と台車枠13との間には、ボールネジシリンダ15が車体幅方向に配設されている。このボールネジシリンダ15は、ナット部材16と該ナット部材16に螺合するボルト部材17とで構成され、振子梁11の前面又は後面のいずれか一面に配置されている。ナット部材16は、振子梁11の前面及び後面を挟むように配置された台車枠13の横梁18,18の一方に基端をピン19にて上下方向に回動可能に設けられている。ボルト部材17は、振子梁11に基端をピン20にて上下方向に回動可能に設けられた筒部材21に回転可能に支持されている。
【0008】
筒部材21は、スラスト軸受22,22を介してボルト部材17の頭部側軸部を支持し、該ボルト部材17の頭部側軸部のスラスト軸受22,22間にはベベルギア23が固設され、該ベベルギア23には、ボルト部材17の頭部側軸部に直交して車体前後方向に設けられた入力軸24のベベルギア25が噛み合っている。
【0009】
また、振子梁11には、ボルト部材17の取付側面と反対側の面に、電動駆動源であるサーボモータ26と変速装置27とが設けられている。変速装置27は、筒部材21の取付位置に車体前後方向に対応して設けられ、該変速装置27の出力軸28は、中間スプライン付ユニバーサルジョイント29を介して前記筒部材21の入力軸24に接続されている。サーボモータ26は、変速装置27とは中心ピン30を挟んで反対側の振子梁11内に設けられ、該サーボモータ26の出力軸31は、入出力方向変換装置32に接続され、該入出力方向変換装置32と前記変速装置27とは、両端にユニバーサルジョイントを備えたシャフト33で接続されている。なお、シャフト33の先端33aを変速装置27から突出させることにより、故障時の手動アクセス部とすることができる。
【0010】
この構成により、図5に示される静止状態から、サーボモータ26の駆動でボルト部材17を回転して、ボルト部材17とナット部材16の螺合位置を変え、ボールネジシリンダ15の長さを変更することによって、図6に示される車体傾斜状態とすることができる。
【0011】
したがって、電気システムで車体傾斜を制御でき、油圧システムに比較して、重量が軽くてコストも安く、正確な位置制御及び応答の早い制御が可能で、メンテナンスも容易である。また、振子梁11の一面にボールネジシリンダ15を配置し、他面にサーボモータ26と変速装置27とを配置したので、スペース的な制約が少ない。
【0012】
図7は、サーボモータ26を車体10側に取り付けた参考例を示すもので、サーボモータ26は、変速装置27、中間スプライン付ユニバーサルジョイント29、入出力方向変換装置32を介してボルト部材17を回転する。この構成は、振子梁11内にサーボモータ26を格納できない場合に有利である。また、図8は、台車枠13にナット部材16の軸方向に制約がある場合に、ナット部材16の支持をトラニオンタイプとした本発明の第実施形態例を示すものである。
【0013】
なお、上記実施形態例では、振子装置をガイドレール12とガイドブロック14とで構成されるもので説明したが、コロ式の振子装置あるいはハの字リンク傾斜装置でも本発明は適用可能であり、また、台車枠13にボルト部材17を、振子梁11にナット部材16をそれぞれ設け、ナット部材16を回転する構成でも良い。
【0014】
【発明の効果】
以上説明したように、本発明は、台車枠と振子梁との間に、ボールネジシリンダを配設し、振子梁又は車体に設けた電動駆動源により、ボールネジシリンダの長さを変更することによって車体傾斜状態とすることができるから、電気システムで車体傾斜を制御でき、油圧システムに比較して、重量が軽くてコストも安く、正確な位置制御及び応答の早い制御が可能で、メンテナンスも容易である。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle body tilting device for a railway vehicle that tilts the vehicle body so that the vehicle travels on a curved track at high speed without impairing the ride comfort.
[0002]
[Prior art]
As a body tilting device, place the pendulum center at a position higher than the center of gravity of the vehicle body, and use the centrifugal force acting on the center of gravity of the vehicle body when traveling on a curved track to rotate the vehicle body around the center of the pendulum so There is a natural pendulum type that moves to the side. As this natural pendulum type, for example, as shown in FIG. 9, a pair of left and right cylindrical rollers 4, 4 are disposed between a pendulum beam 2 at the bottom of the vehicle body 1 and a carriage frame 3. , 4 and the guide rail formed along the trajectory of the pendulum movement, as shown in Utility Model Registration No. 2556312, and the pendulum of the guide rail There are a guide block having a guide portion that allows movement only in the direction, and a plurality of rolling balls disposed between ball rolling grooves provided in the guide rail and the guide portion, respectively. In order to assist this movement, as shown in FIG. 10, a pneumatic cylinder 5 is disposed between the pendulum beam 2 and the carriage frame 3, and the vehicle body is tilted by expansion and contraction of the pneumatic cylinder 5. is there.
[0003]
[Problems to be solved by the invention]
However, if you want to run a curved track at a higher speed with the above structure, the pendulum center must be positioned near the center of gravity of the car body. However, if the pendulum center is lowered, the centrifugal force acting on the car body center of gravity will tilt the car body. Since there is no large moment in the desired direction, the pneumatic cylinder becomes large in shape and is limited in space. Therefore, if a hydraulic cylinder is used, it is disadvantageous in terms of weight and cost because it builds a hydraulic system including a hydraulic pump and hydraulic piping and an electric system for hydraulic control, and the hydraulic system has a time lag until the hydraulic pressure rises. Therefore, there is a concern about the delay in vehicle body tilt control. Furthermore, it is necessary to pay attention to hydraulic oil contamination (contamination of dust), which is very troublesome in terms of maintenance.
[0004]
Therefore, the present invention provides a vehicle body tilting device for a railway vehicle that is operated by an electric system, is lighter in weight and less expensive than a hydraulic system, enables accurate position control and quick response control, and is easy to maintain. It is intended to provide.
