Abstract

PROBLEM TO BE SOLVED: To provide a pendulum bogie for a railway vehicle improved in safety by avoiding the separation of a vehicle body and the bogie even if an excessive large fore-and-aft load such as an impact or the like at a collision with an obstacle is applied to the bogie, and to provide the railway vehicle equipped with the pendulum bogie.SOLUTION: A roller 140 is rotatably held at a roller holding part 144 arranged at the side of a bogie frame 150. A pendulum weight 120 can oscillate in the vehicle width direction by the movement of a roller receiver contacting with the roller 140 while the roller receiver 130 rotates the roller 140. A stopper 145 serving as a receiver for the roller receiver 130 is arranged at a roller holding part 144. Since the stopper 145 is limited in relative movement not smaller than a gap 173 in the fore-and-aft direction of the vehicle body between the roller receiver 130 and itself, the separation of the roller receiver 130 at the side of the vehicle body and the bogie frame 150 at the side of the bogie can be suppressed even if the excessive large fore-and-aft load is applied to the bogie due to the action of an impact to the longitudinal direction of the vehicle body at the collision or the like with the obstacle.

Description

本発明は、車体を揺動可能にして曲線軌道を高速で通過することを可能とした鉄道車両用振り子台車及びそれを備えた鉄道車両に関する。   The present invention relates to a pendulum trolley for a railway vehicle that can swing a vehicle body and pass through a curved track at a high speed, and a railway vehicle including the same.

従来の鉄道車両用台車においては、台車枠上に配置された回転自在のコロの上に振り子梁を載せており、曲線部において振り子梁がコロ上を揺動することにより、振り子梁上に配置された空気バネを介して支持される車体を傾斜させて遠心力を減少させることで、曲線を高速で通過することを可能とした振り子式台車がある(特許文献1参照)。   In conventional railcar bogies, the pendulum beam is placed on a rotatable roller placed on the bogie frame, and the pendulum beam swings on the roller at the curved portion, so it is placed on the pendulum beam. There is a pendulum cart that can pass through a curve at a high speed by tilting a vehicle body supported via an air spring and reducing centrifugal force (see Patent Document 1).

従来の振り子式鉄道車両では、車体が傾斜する構造上、振り子梁はコロ上に載せられているのみであり、台車に固定されていない。   In the conventional pendulum type railway vehicle, the pendulum beam is only mounted on the roller because of the structure in which the vehicle body is inclined, and is not fixed to the carriage.

特開平04−201670号公報Japanese Patent Laid-Open No. 04-201670

従来の鉄道車両用振り子台車では、上記のように、台車と車体間が振り子機構によって車体幅方向に揺動可能に構成されているので、台車と車体間の前後力(車体長手方向に作用する力)の伝達は、台車枠に取り付けられた前後力を伝達する前後力伝達コロを介して振り子梁に伝えられる。しかしながら、基本的に振り子梁は台車に固定されていないので、従来の構造では、衝突等の予期せぬ過大な前後力が作用した場合、振り子梁が台車から分離してしまう懸念があった。   As described above, the conventional pendulum trolley for a railway vehicle is configured such that the space between the trolley and the vehicle body can be swung in the vehicle body width direction by the pendulum mechanism. The force is transmitted to the pendulum beam via a longitudinal force transmission roller that transmits the longitudinal force attached to the carriage frame. However, since the pendulum beam is basically not fixed to the carriage, the conventional structure has a concern that the pendulum beam may be separated from the carriage when an unexpected excessive longitudinal force such as a collision is applied.

そこで、台車が振り子台車である場合、振り子梁を台車に対して車体幅方向に揺動可能にしつつ、衝突等の過大な前後力に起因して振り子梁が台車から分離する方向に力が作用する場合であっても、振り子梁が台車から分離するのを抑制する点で解決すべき課題がある。
本発明の目的は、障害物との衝突時等のような過大な前後荷重が負荷された場合など、車体と台車とが分離する方向に力が作用する場合であっても、車体と台車とが分離しにくく、安全性を向上させた鉄道車両用振り子台車及びそれを備えた鉄道車両を提供することである。
Therefore, when the cart is a pendulum cart, the pendulum beam can swing in the vehicle body width direction with respect to the cart, and a force acts in a direction in which the pendulum beam separates from the cart due to an excessive longitudinal force such as a collision. Even in this case, there is a problem to be solved in that the pendulum beam is prevented from separating from the carriage.
The object of the present invention is that even if a force acts in the direction in which the vehicle body and the carriage are separated, such as when an excessive longitudinal load is applied, such as when a collision with an obstacle occurs, It is an object of the present invention to provide a pendulum trolley for a railway vehicle that is difficult to separate and has improved safety, and a railway vehicle equipped with the same.

本発明による鉄道車両用振り子台車は、台車を構成する台車枠と、前記台車枠と前記車体との間に備えられるとともに、前記車体をその幅方向に揺動可能に支持する振り子機構とを備える鉄道車両用振り子台車であって、前記振り子機構は、前記台車枠に回転自在に保持されたコロと、前記車体側に保持されており前記コロにころがり接触するコロ受けを備える振り子梁と、前記コロ受けの端部に転がり接触するとともに、前記台車と前記車体との間の前記車体の長手方向の力を伝達する前後力伝達コロと、を有する鉄道車両用振り子台車において、前記コロ受けの端部に対して前記車体の長手方向に隙間を置いて配置されるとともに、前記台車と前記コロ受けとの分離を抑制する受けを備えること、を特徴としている。   A pendulum bogie for a railway vehicle according to the present invention includes a bogie frame constituting the bogie, and a pendulum mechanism that is provided between the bogie frame and the vehicle body and supports the vehicle body so as to be swingable in the width direction thereof. A pendulum cart for a railway vehicle, wherein the pendulum mechanism includes a roller rotatably held on the carriage frame, a pendulum beam including a roller receiver held on the vehicle body side and in contact with the roller. In a pendulum trolley for a railway vehicle, comprising a front and rear force transmission roller that is in rolling contact with an end portion of a roller receiver and transmits a longitudinal force between the carriage and the vehicle body, the end of the roller receiver It is characterized by comprising a receiver that is arranged with a gap in the longitudinal direction of the vehicle body with respect to the part and that suppresses separation between the carriage and the roller receiver.

この鉄道車両用振り子台車によれば、振り子梁に備わるコロ受けの端部に対して車体長手方向に隙間を設けるように、台車枠側に配置されている受けは、コロ受けとの隙間以上の車体長手方向への相対動きを制限するストッパの作用を奏する。したがって、障害物等との衝突などの際に車体長手方向に過大な前後荷重が負荷されたときにも、コロ受けと台車枠との間で生じようとする車体長手方向の相対変位は、受けが奏するストッパの作用で制限され、車体と台車とが分離することはない。   According to this railcar pendulum carriage, the receiver disposed on the side of the carriage frame has a gap larger than the gap with the roller receiver so that a gap is provided in the longitudinal direction of the vehicle body with respect to the end of the roller receiver provided on the pendulum beam. It acts as a stopper that limits relative movement in the longitudinal direction of the vehicle body. Therefore, even when an excessive longitudinal load is applied in the longitudinal direction of the vehicle body in the event of a collision with an obstacle, the relative displacement in the longitudinal direction of the vehicle body that is about to occur between the roller receiver and the carriage frame is Is limited by the action of the stopper, and the vehicle body and the carriage do not separate.

また、この発明は、鉄道車両用振り子台車が適用された鉄道車両、即ち、当該鉄道車両用振り子台車に支持された車体を備えていることを特徴とする鉄道車両に関する。   The present invention also relates to a railway vehicle to which a railway vehicle pendulum carriage is applied, that is, a railway vehicle having a vehicle body supported by the railway vehicle pendulum carriage.

本発明によれば、車体に備えられる振り子梁を台車に対して車体幅方向に揺動可能に保持しつつ、衝突等の過大な前後力に起因して振り子梁(車体)が台車から分離する方向に力が作用する場合であっても、振り子梁が台車から分離することを抑制できる高い安全性を備える鉄道車両用振り子台車及びそれを備えた鉄道車両を提供することができる。   According to the present invention, the pendulum beam (vehicle body) is separated from the cart due to an excessive longitudinal force such as a collision while holding the pendulum beam provided on the vehicle body so as to be swingable in the vehicle body width direction with respect to the cart. Even when a force acts in the direction, it is possible to provide a railway vehicle pendulum trolley having high safety that can prevent the pendulum beam from being separated from the trolley, and a railway vehicle including the same.

The air springs 110, 110 are arranged on the left and right (the width direction 500 of the vehicle body 11) on the pendulum beam 120 in the center in the longitudinal direction of the vehicle 100, and the vehicle body 11 is connected to the vehicle 100 via the air springs 110, 110. It is supported by. The pendulum mechanism is disposed between the carriage frame 150 and the pendulum beam 120.

台車100は、鉄道車両が走行する軌道1(図1、2参照)に沿って車体幅方向500に離置される二本の側梁154,154と、当該両側梁154,154の長手方向中央部に配設されるとともに両側梁154,154を接続する横梁152とからなる台車枠150を備えている。台車100は、また、図3及び図4には示さないが、側梁154の長手方向の両端部に回動可能に支持される輪軸(車軸の両端部に車輪を備えたもの、図2参照)を備えている。台車100は、更に、振り子梁120と横梁152とを連結して車体11の台車100に対する傾斜を制御するシリンダ装置160を備えている。   The bogie 100 includes two side beams 154 and 154 that are spaced apart in the vehicle body width direction 500 along a track 1 (see FIGS. 1 and 2) on which the railway vehicle travels, and the longitudinal center of the side beams 154 and 154. A carriage frame 150 is provided that is arranged in the section and includes a cross beam 152 that connects both side beams 154 and 154. Although not shown in FIGS. 3 and 4, the carriage 100 is a wheel shaft that is rotatably supported at both ends in the longitudinal direction of the side beam 154 (wheels provided at both ends of the axle, see FIG. 2). ). The carriage 100 further includes a cylinder device 160 that controls the inclination of the vehicle body 11 with respect to the carriage 100 by connecting the pendulum beam 120 and the lateral beam 152.

横梁152の各端部と当該端部に対応する側梁154との接続部の上面には、コロ140を回転自在に保持するコロ保持部144が備えられており、コロ保持部144には、円筒形状のコロ140がその軸を軌道1(車体11)の長手方向に沿って配置した態様で回転自在に保持されている。横梁152について車体11の幅方向両端に備わる一対のコロ140,140の上方には、台車枠150をなす横梁152の長手方向に沿う態様で振り子梁120が配設されており、振り子梁120は、その両端部の下面に、コロ140,140がころがり接触する滑らかに形成された曲面を持つように構成されたコロ受け130,130を備えている。振り子梁120は、当該曲面がコロ140,140を回転させながら移動することで車体幅方向に揺動することができる。コロ受け130,130を備える振り子梁120は、下に向けて凸状の形態をなしている。   A roller holding portion 144 that rotatably holds the roller 140 is provided on the upper surface of the connection portion between each end portion of the horizontal beam 152 and the side beam 154 corresponding to the end portion, and the roller holding portion 144 includes: A cylindrical roller 140 is rotatably held in such a manner that its axis is disposed along the longitudinal direction of the track 1 (vehicle body 11). A pendulum beam 120 is disposed above the pair of rollers 140 and 140 provided at both ends in the width direction of the vehicle body 11 with respect to the horizontal beam 152 in a manner along the longitudinal direction of the horizontal beam 152 forming the carriage frame 150. The roller receivers 130 and 130 are formed on the lower surfaces of the both ends so that the rollers 140 and 140 have a smoothly formed curved surface in contact with the rollers. The pendulum beam 120 can swing in the vehicle body width direction as the curved surface moves while rotating the rollers 140 and 140. The pendulum beam 120 including the roller receivers 130 and 130 has a convex shape facing downward.

図4は、図3に示す振り子梁120とコロ受け130及びコロ140とを有する振り子機構が振り子動作した時の拡大図である。振り子機構は、車体11をその長手方向に沿う軸周りに回転させて傾斜させるもので、車体11を台車100,100上で回転傾斜させる時の軸を車体11の床面の上方に設定するとともに、車体11の重心をその軸の下方に設定している。こうした回転軸と重心との配置によって、車両10(図1及び図2参照)が曲線軌道を通過する時に生じる遠心力又はシリンダ装置160の作動により、振り子梁120に備えられるコロ受け130,130がコロ140,140と接触し且つ回転させながら移動し、この振り子梁120の振り子動作によって車体11が傾斜する。   FIG. 4 is an enlarged view when the pendulum mechanism having the pendulum beam 120, the roller receiver 130, and the roller 140 shown in FIG. The pendulum mechanism rotates and tilts the vehicle body 11 about an axis along the longitudinal direction thereof, and sets the axis for rotating and tilting the vehicle body 11 on the carriages 100 and 100 above the floor surface of the vehicle body 11. The center of gravity of the vehicle body 11 is set below the axis. Due to the arrangement of the rotation shaft and the center of gravity, the roller receivers 130 and 130 provided in the pendulum beam 120 are caused by the centrifugal force generated when the vehicle 10 (see FIGS. 1 and 2) passes through the curved track or the operation of the cylinder device 160. It moves while contacting and rotating the rollers 140, 140, and the vehicle body 11 is tilted by the pendulum operation of the pendulum beam 120.

図5は、図2及び図3において破線で囲んだ領域Cを拡大して、振り子機構の詳細を示す断面図である。また、図6は図5においてD−Dで示した切断面での断面図であり、図7は図5においてE−Eで示した切断面での断面図である。   FIG. 5 is a cross-sectional view showing details of the pendulum mechanism by enlarging a region C surrounded by a broken line in FIGS. 2 and 3. 6 is a cross-sectional view taken along the line DD in FIG. 5, and FIG. 7 is a cross-sectional view taken along the line EE in FIG.

各コロ140は、コロ保持部144により台車枠150の側梁154と横梁152との接続部の上面に取り付けられている。具体的には、コロ保持部144は、車両長手方向510(図6参照)に延びる支持軸147をその長手方向に離間した端部148,148で保持している。コロ140は、支持軸147に対して軸受149,149を介して回転自在に支持されている。車体11は、車体側である振り子梁120に設けられているコロ受け130が回転自在なコロ140を介して支持されている。振り子梁120は、車体11が円滑に傾斜するためにコロ140上に載せられている構造となっている。   Each roller 140 is attached to the upper surface of the connecting portion between the side beam 154 and the horizontal beam 152 of the carriage frame 150 by a roller holding portion 144. Specifically, the roller holding portion 144 holds a support shaft 147 extending in the vehicle longitudinal direction 510 (see FIG. 6) with end portions 148 and 148 spaced in the longitudinal direction. The roller 140 is rotatably supported with respect to the support shaft 147 via bearings 149 and 149. The vehicle body 11 is supported via a roller 140 that can freely rotate a roller receiver 130 provided on the pendulum beam 120 on the vehicle body side. The pendulum beam 120 has a structure that is placed on the roller 140 so that the vehicle body 11 can be smoothly inclined.

上記構造によれば、振り子式鉄道車両が曲線軌道を通過する際に受ける遠心力又はシリンダ装置160によって傾くとき、コロ受け130がコロ140を回転させつつコロ140と接触しながら移動することで振り子動作をする。したがって、振り子式鉄道車両は、コロ140上を振り子梁120が揺動することで、車体11を円滑に傾斜することが可能である。また、前後方向の駆動力及びブレーキ力の伝達は、詳細は後述するが、前後力伝達コロ146にて行われる。   According to the above structure, when the pendulum railway vehicle is tilted by the centrifugal force or the cylinder device 160 received when passing through the curved track, the roller receiver 130 moves while contacting the roller 140 while rotating the roller 140, thereby causing the pendulum. To work. Therefore, the pendulum type railway vehicle can smoothly tilt the vehicle body 11 by swinging the pendulum beam 120 on the roller 140. In addition, the transmission of the driving force and the braking force in the front-rear direction is performed by the front-rear force transmission roller 146, which will be described in detail later.

コロ受け130、コロ140及び前後力伝達コロ146の構造だけの振り子機構であると、障害物との衝突時など車両10に予期せぬ過大な前後力が負荷された場合、後述するような前後力伝達コロ146のみで過大且つ衝撃的な前後力を支持することができず、またコロ受け130については、上下方向に拘束されていないことから、前後力と合わせて上下力(特に、台車100を車体11から引き離す方向の力)が負荷された場合、台車100から車体11が離脱してしまう懸念がある。   When the pendulum mechanism has only the structure of the roller receiver 130, the roller 140, and the longitudinal force transmission roller 146, when an unexpected excessive longitudinal force is applied to the vehicle 10 such as when it collides with an obstacle, Since the force transmission roller 146 alone cannot support an excessive and shocking longitudinal force, and the roller receiver 130 is not restrained in the vertical direction, the vertical force (particularly, the carriage 100) is combined with the longitudinal force. When a force in the direction of pulling the vehicle away from the vehicle body 11 is applied, the vehicle body 11 may be detached from the carriage 100.

そこで、上記問題を解決する手段として、図5から図7に示す本発明による鉄道車両用振り子台車の実施例では、振り子梁120の長手方向の両下面に備えられるコロ受け130,130の長手方向(車体幅方向500)に沿って、コロ受け130の幅方向(車体長手方向510)の端部と噛みあうように、受けとしてのストッパ145,145を配設している。なお、図5では、ストッパ145,145の間に1個の前後力伝達コロ146を備えているが、ストッパ145を3分割し、ストッパ145同士の間に2個の前後力伝達コロを備えても良い。   Therefore, as a means for solving the above problem, in the embodiment of the railcar pendulum carriage according to the present invention shown in FIGS. 5 to 7, the longitudinal direction of the roller receivers 130, 130 provided on both lower surfaces of the pendulum beam 120 in the longitudinal direction. Stoppers 145 and 145 serving as receivers are arranged along the (vehicle body width direction 500) so as to mesh with the end portions of the roller receiver 130 in the width direction (vehicle body longitudinal direction 510). In FIG. 5, one longitudinal force transmission roller 146 is provided between the stoppers 145 and 145, but the stopper 145 is divided into three parts and two longitudinal force transmission rollers are provided between the stoppers 145. Also good.

各コロ保持部144は、軸受149,149を介してコロ140を回転自在に支持する支持軸147を保持するために軸保持部170,170と、当該軸保持部170,170から一体的に且つコロ140から離れる方向(車体長手方向510の方向)に延びる延長部171,171とを備えている。各延長部171には、前後力伝達コロ146がボルトなどで回転自在に固定されている。車両10が発車(加速)したり停車(減速)したりする際に生じる車体長手方向510に沿う前後方向の力が作用する場合には、延長部171に備えられる前後力伝達コロ146がコロ受け端部131に当接して、これらの力を台車100から車体11へと伝達する。車体11が振り子動作する際には、前後力伝達コロ146はコロ受け130の幅方向(車体長手方向510に沿う方向)の端部のコロ受け端部131を回動可能に案内する。   Each roller holding portion 144 is integrally formed with the shaft holding portions 170 and 170 and the shaft holding portions 170 and 170 in order to hold a support shaft 147 that rotatably supports the roller 140 via bearings 149 and 149. Extension portions 171 and 171 extending in the direction away from the roller 140 (the direction of the vehicle body longitudinal direction 510) are provided. A longitudinal force transmission roller 146 is rotatably fixed to each extension portion 171 with a bolt or the like. When a longitudinal force acting along the vehicle body longitudinal direction 510 occurs when the vehicle 10 starts (accelerates) or stops (decelerates), the longitudinal force transmission roller 146 provided in the extension portion 171 receives the roller. Abutting against the end 131, these forces are transmitted from the carriage 100 to the vehicle body 11. When the vehicle body 11 performs a pendulum operation, the longitudinal force transmission roller 146 guides the roller receiving end 131 at the end of the roller receiver 130 in the width direction (the direction along the vehicle body longitudinal direction 510) in a rotatable manner.

振り子機構の組立て状態では、コロ受け端部131とストッパ145との間には車体長手方向510の方向に隙間173を設けた状態でストッパ145は延長部171に取付けボルト172で固定されている。このため、車両10が振り子動作時にはコロ受け130が車体幅方向へ揺動する動作、即ち、車体の傾斜動作を阻害しない構造となっている。   In the assembled state of the pendulum mechanism, the stopper 145 is fixed to the extension 171 with the mounting bolt 172 in a state where a gap 173 is provided between the roller receiving end 131 and the stopper 145 in the longitudinal direction 510 of the vehicle body. For this reason, when the vehicle 10 is operated as a pendulum, the roller receiver 130 swings in the vehicle body width direction, that is, the vehicle body tilting operation is not hindered.

ストッパ145は、コロ受け130のコロ受け端部131を上下方向に拘束する構造を備えている。即ち、ストッパ145は、例えばコロ受け130のコロ140と接触する側とは反対側において、コロ受け端部131に係合する係合部174を備えている。係合部174は、コロ受け130がコロ140から離れる方向への動きを拘束する。なお、係合部174は、コロ受け130を上下方向に拘束する機能を備えていれば良く、図示のような形状・構造に限られず、例えばコロ受け130内の溝に係合するなどの構造でもよい。本構造によれば、車両が障害物に衝突するなど、過大な前後力が負荷された場合においても、ストッパ145がコロ受け130との間で前後力を吸収すると同時に、係合部174がコロ受け130を上下方向にも拘束することから、台車100と車体11が分離することない。そのため、従来構造に対して衝突時等の予期せぬ過大な力が車体11と台車100との間に生じた場合であっても、車体11と台車100との分離を抑制することができるため安全性を向上させることができる。   The stopper 145 has a structure for restraining the roller receiving end 131 of the roller receiver 130 in the vertical direction. That is, the stopper 145 includes an engaging portion 174 that engages with the roller receiving end 131 on the side opposite to the side of the roller receiving 130 that contacts the roller 140, for example. The engaging portion 174 restrains the movement of the roller receiver 130 in the direction away from the roller 140. The engaging portion 174 only needs to have a function of restraining the roller receiver 130 in the vertical direction, and is not limited to the shape and structure as shown in the figure. For example, the engagement portion 174 is engaged with a groove in the roller receiver 130. But you can. According to this structure, even when an excessive longitudinal force is applied such as when the vehicle collides with an obstacle, the stopper 145 absorbs the longitudinal force with the roller receiver 130, and at the same time, the engaging portion 174 has a roller. Since the support 130 is also restrained in the vertical direction, the carriage 100 and the vehicle body 11 are not separated. Therefore, even if an unexpected excessive force such as a collision occurs between the vehicle body 11 and the carriage 100 with respect to the conventional structure, separation of the vehicle body 11 and the carriage 100 can be suppressed. Safety can be improved.
