Description

本発明は、鉄道車両の車軸と台車枠とを接続する軸箱支持装置に関する。
軸箱支持装置は、台車枠と車軸との間の上下方向の荷重をコイルばねで、水平方向荷重を該コイルばね内の円筒空間内に設置した円筒積層ゴムで、分担して受持つ。
The present invention relates to an axle box support device that connects an axle of a railway vehicle and a bogie frame.
The axle box support device shares and handles the load in the vertical direction between the carriage frame and the axle with a coil spring and the horizontal load with a cylindrical laminated rubber installed in a cylindrical space in the coil spring.

従来の鉄道車両の軸箱支持装置として、特許文献1〜特許文献3のように、ウイング式軸箱支持装置がある。

As conventional axle box support devices for railway vehicles, there are wing-type axle box support devices as in Patent Documents 1 to 3.
JP 1990-106463 A JP 2002-331930 A JP 2002-362362 A

従来のウイング式軸箱支持装置は、コイルばねにより上下荷重を支持し、円筒積層ゴムにより、台車枠に対して、軸箱体を、前後・左右方向へ支持する構成となっている。
また、円筒積層ゴムは、コイルばねの内側、かつ、車軸中心高さの水平方向の延長線上に配置されている。
このため、円筒積層ゴムの外径を、コイルばねの内径よりも大きくすることができない。
A conventional wing-type axle box support device is configured to support the vertical load by a coil spring and to support the axle box body in the front-rear and left-right directions with respect to the carriage frame by a cylindrical laminated rubber.
Further, the cylindrical laminated rubber is disposed on the inner side of the coil spring and on the horizontal extension line of the axle center height.
For this reason, the outer diameter of the cylindrical laminated rubber cannot be made larger than the inner diameter of the coil spring.

これにより、円筒積層ゴムの前後方向のばね定数を小さくするのには限りがあり、曲線通過時の横圧の低減効果にも限界があるという問題点があった。
これに対して、コイルばねの径を大きくして、円筒積層ゴムの外径を大きくすることが可能である。
As a result, there is a limit to reducing the spring constant in the front-rear direction of the cylindrical laminated rubber, and there is a problem in that there is a limit to the effect of reducing the lateral pressure when passing through the curve.
On the other hand, it is possible to increase the outer diameter of the cylindrical laminated rubber by increasing the diameter of the coil spring.

しかし、この場合、軸箱体が大きくなる問題点がある。
本発明の目的は、曲線通過時の横圧を低減でき、小さな軸箱体を有する台車を提供することにある。
However, in this case, there is a problem that the shaft box becomes large.
An object of the present invention is to provide a carriage having a small axle box body that can reduce the lateral pressure when passing a curve.

上記課題を解決するために、本発明は、鉄道車両の車軸を支持した軸箱体からコイルばねを介して台車枠を弾性支持しており、コイルばねの下端部または上端部に、該コイルばねと同心にゴムを配置している鉄道車両の軸箱支持装置において、前記ゴムは内筒と外筒との間にゴムを配置しており、該ゴムは、車軸の中心の水平方向線よりも上方または下方にあること、を特徴とする鉄道車両の軸箱支持装置によって達成できる。   In order to solve the above-described problems, the present invention elastically supports a bogie frame via a coil spring from a shaft box body that supports an axle of a railway vehicle, and the coil spring is provided at a lower end portion or an upper end portion of the coil spring. In the railway car axle box support device in which the rubber is arranged concentrically with the rubber, the rubber is arranged between the inner cylinder and the outer cylinder, and the rubber is more than the horizontal line at the center of the axle. It can be achieved by a rail car axle box support device characterized by being above or below.

かかる構成により、円筒積層ゴムの外径をコイルばねの内径にとらわれることなく大きくできる。
このため、円筒積層ゴムの前後方向にばね定数を小さくでき、曲線通過時の横圧を低減できる。
また、円筒積層ゴムは、車軸の中心の延長線上よりも下方または上方にあるので、小さな軸箱体を有する台車にできる。
With this configuration, the outer diameter of the cylindrical laminated rubber can be increased without being constrained by the inner diameter of the coil spring.
For this reason, a spring constant can be made small in the front-back direction of cylindrical laminated rubber, and the lateral pressure at the time of a curve passage can be reduced.
Further, since the cylindrical laminated rubber is located below or above the extension line at the center of the axle, it can be a cart having a small axle box.

以下、図面を参照して本発明の実施形態を説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

以下に、本発明の第1の実施形態を図1〜図7に基づいて説明する。
図1において、鉄道車両用台車2は、輪軸4を回転可能な状態で保持している軸箱体6、車体1を空気ばね5を介して弾性支持する台車枠3によりに構成される。軸箱支持装置はウイング式であり、車軸4の両端と台車枠3とをコイルばね12を介して支持している。
Below, the 1st Embodiment of this invention is described based on FIGS.
In FIG. 1, a railcar bogie 2 includes a shaft box 6 that holds a wheel shaft 4 in a rotatable state, and a bogie frame 3 that elastically supports a vehicle body 1 via an air spring 5. The axle box support device is a wing type, and supports both ends of the axle 4 and the carriage frame 3 via a coil spring 12.

図2において、軸箱体6は、2つのコイルばね12により台車枠3を上下方向に支持している。また、コイルばね12の下部と軸箱体6との間に円筒積層ゴム22を配置している。   In FIG. 2, the axle box 6 supports the carriage frame 3 in the vertical direction by two coil springs 12. A cylindrical laminated rubber 22 is disposed between the lower part of the coil spring 12 and the shaft box body 6.

以下、円筒積層ゴム22を図3によって説明する。
図3において、軸箱支持装置は、台車枠3、軸箱体6、台車枠3と軸箱体6とを鉛直方向に接続するピン11、コイルばね12、コイルばね12の下端と軸箱体6との間に配置したコイルばね座15、コイルばね12の上端と台車枠3との間に配置したばね座16、円筒積層ゴム22の半径方向端部と軸箱体6との間に配置したゴム座21により主に構成される。
ピン11は台車枠3と軸箱体6との間に垂直方向に挿入されている。ピン11の上部が台車枠3の穴に挿入されており、ピン11の上部から水平方向に突出したフランジがコイルばね12を受けるばね座16になっている。
Hereinafter, the cylindrical laminated rubber 22 will be described with reference to FIG.
In FIG. 3, the axle box support device includes a carriage frame 3, an axle box body 6, a pin 11 that connects the carriage frame 3 and the axle box body 6 in the vertical direction, a coil spring 12, a lower end of the coil spring 12, and an axle box body. The coil spring seat 15 is disposed between the upper end of the coil spring 12 and the carriage frame 3, and is disposed between the radial end of the cylindrical laminated rubber 22 and the shaft box body 6. The rubber seat 21 is mainly configured.
The pin 11 is inserted between the carriage frame 3 and the axle box body 6 in the vertical direction. An upper portion of the pin 11 is inserted into a hole of the bogie frame 3, and a flange projecting horizontally from the upper portion of the pin 11 is a spring seat 16 that receives the coil spring 12.

円筒積層ゴム22は、ゴム22b、金属板22cとが交互に半径方向に積層されている。ゴム22b、金属板22cは半円状である。積層された中心の金属板22dは円筒状である。中心の金属板22dはピン11の下端部に下方から上方に向けて挿入されている。これにより、円筒積層ゴム22の中心とコイルばね12の中心が一致する。半径方向に積層したゴム22b、金属板22cはその円周方向において、欠けている。この欠けた部分22eを間隙部という。間隙部22e,22eはピン11を中心にして車体1の前後方向において、対向している。   In the cylindrical laminated rubber 22, rubber 22b and metal plates 22c are alternately laminated in the radial direction. The rubber 22b and the metal plate 22c are semicircular. The laminated central metal plate 22d is cylindrical. The central metal plate 22d is inserted into the lower end portion of the pin 11 from below to above. Thereby, the center of the cylindrical laminated rubber 22 and the center of the coil spring 12 coincide. The rubber 22b and the metal plate 22c laminated in the radial direction are missing in the circumferential direction. This missing portion 22e is called a gap. The gap portions 22e and 22e face each other in the front-rear direction of the vehicle body 1 with the pin 11 as the center.

円筒積層ゴム22の高さは、外周側が低く(小さく)、ピン11側が高い(大きい)。
円筒積層ゴム22の外径はコイルばね12の内径よりも大きい。このため、円筒積層ゴム22はコイルばね12の下端よりも下方にある。
車軸4の中心の水平方向位置よりもL寸法下方に円筒積層ゴム22の高さ方向の中心位置がある。
The height of the cylindrical laminated rubber 22 is low (small) on the outer peripheral side and high (large) on the pin 11 side.
The outer diameter of the cylindrical laminated rubber 22 is larger than the inner diameter of the coil spring 12. For this reason, the cylindrical laminated rubber 22 is located below the lower end of the coil spring 12.
The center position in the height direction of the cylindrical laminated rubber 22 is located below the horizontal position at the center of the axle 4 by the L dimension.

ゴム座21は軸箱体6の上面6bに載ったフランジ21bに垂直な円筒21cを設けている。円筒21cは軸箱体6の穴に挿入されている。ゴム座21の円筒21cの下端部は小径になっており、これに円筒積層ゴム22の外周部の下端が掛かり、円筒積層ゴム22の落下を防止できる。   The rubber seat 21 is provided with a cylinder 21c perpendicular to the flange 21b mounted on the upper surface 6b of the axle box 6. The cylinder 21 c is inserted into the hole of the shaft box body 6. The lower end portion of the cylinder 21c of the rubber seat 21 has a small diameter, and the lower end of the outer peripheral portion of the cylindrical laminated rubber 22 is hung on this, so that the cylindrical laminated rubber 22 can be prevented from falling.

円筒積層ゴム22はゴム座21の円筒21bに上方から圧入され、円筒積層ゴム22の外周部の上端を押え金22hで円筒積層ゴム22が上方に抜けるのを防止している。押え金22hは円筒21cに螺合されて固定されている。
円筒積層ゴム22はピン11に下方からボルト25で締結されている。23は座金、24はばね座である。
円筒積層ゴム22の内径部は金属円筒22d、間座22gを介してピン11に固定される。
また、ゴム座21のフランジ21bの上面にはコイルばね座15があり、コイルばね12を受けている。
The cylindrical laminated rubber 22 is press-fitted into the cylinder 21b of the rubber seat 21 from above, and the upper end of the outer peripheral portion of the cylindrical laminated rubber 22 is prevented from being pulled upward by a presser foot 22h. The presser foot 22h is screwed and fixed to the cylinder 21c.
The cylindrical laminated rubber 22 is fastened to the pin 11 with a bolt 25 from below. Reference numeral 23 is a washer, and 24 is a spring washer.
An inner diameter portion of the cylindrical laminated rubber 22 is fixed to the pin 11 via a metal cylinder 22d and a spacer 22g.
A coil spring seat 15 is provided on the upper surface of the flange 21 b of the rubber seat 21 and receives the coil spring 12.

また、図6において、コイルばね座15に、鉛直方向に突出片15cがあり、図7に示すように、突出片15cは円筒積層ゴム22の間隙部22eに配置されている。
このため、台車枠3に対して、軸箱体6が大きく変位(台車枠3に対して軸箱体6が前後方向(X方向)に変位すること。)した時に、円筒積層ゴム22の金属円筒22dに突出片15cがあたるため、加減速時における円筒積層ゴム22の大変位を防止できる。突出片15cと円筒積層ゴム22の金属円筒22dとの間には空間がある。
In FIG. 6, the coil spring seat 15 has a protruding piece 15 c in the vertical direction, and the protruding piece 15 c is disposed in the gap 22 e of the cylindrical laminated rubber 22 as shown in FIG. 7.
For this reason, when the axle box 6 is greatly displaced relative to the carriage frame 3 (the axle box 6 is displaced in the front-rear direction (X direction) relative to the carriage frame 3), the metal of the cylindrical laminated rubber 22 Since the protruding piece 15c hits the cylinder 22d, large displacement of the cylindrical laminated rubber 22 during acceleration / deceleration can be prevented. There is a space between the protruding piece 15 c and the metal cylinder 22 d of the cylindrical laminated rubber 22.

図4において、X方向が前後方向、Y方向が左右方向である。
かかる構成により、円筒積層ゴム22に、図4のX方向(前後方向)に力がかかる場合は、ゴム22bをせん断する方向に、図4のY方向(左右方向)に力がかかる場合は、ゴム22bを圧縮する方向に変形する。
これにより、図4のX方向のばね定数は、Y方向のばね定数よりも小さくなる。
In FIG. 4, the X direction is the front-rear direction and the Y direction is the left-right direction.
With this configuration, when a force is applied to the cylindrical laminated rubber 22 in the X direction (front-rear direction) in FIG. 4, a force is applied in the direction of shearing the rubber 22 b to the Y direction (left-right direction) in FIG. The rubber 22b is deformed in the compressing direction.
Thereby, the spring constant in the X direction in FIG. 4 is smaller than the spring constant in the Y direction.

円筒積層ゴム22はコイルばねの内方ではなく、外方に配置されているので、外径はコイルばね12の内径に制約されないで、円筒積層ゴム22の径を大きくできる。
これにより、円筒積層ゴム22の前後方向のばね定数を小さくすることが、可能となる。
その結果、車軸の前後変位が大きくなることで容易にヨーイング方向へ操舵できるようになるため、車軸の曲線に対する操舵性が良くなり、曲線通過時における横圧低減が可能となる。
Since the cylindrical laminated rubber 22 is disposed not on the inside of the coil spring but on the outside, the outer diameter is not limited by the inner diameter of the coil spring 12, and the diameter of the cylindrical laminated rubber 22 can be increased.
This makes it possible to reduce the spring constant in the front-rear direction of the cylindrical laminated rubber 22.
As a result, since the longitudinal displacement of the axle is increased, the steering in the yawing direction can be easily performed. Therefore, the steering performance with respect to the curve of the axle is improved, and the lateral pressure when passing the curve can be reduced.

また、本発明では、円筒積層ゴム22の前後方向のばね定数が小さいが、例えば、車輪を踏面ブレーキで減速をした場合、台車枠3と軸箱体6の間の変位が大きくなる。
なお、上記実施例では、突出片15cをコイルばね座15の上面から下方に突出させていたが、ゴム座21もしくは軸箱体6の下端から突出片15cを、上方に突出させてもよい。また、ピン11から間隙部22dに突出する突出片15cを設けてもよい。
円筒積層ゴム22は、車軸4の中心の延長線上よりも下方にあるので、円筒積層ゴム22,22間の距離を小さくでき、小さな軸箱体を有する台車にできる。
In the present invention, the spring constant in the front-rear direction of the cylindrical laminated rubber 22 is small. However, for example, when the wheel is decelerated by the tread brake, the displacement between the carriage frame 3 and the axle box 6 becomes large.
In the above-described embodiment, the protruding piece 15c protrudes downward from the upper surface of the coil spring seat 15, but the protruding piece 15c may protrude upward from the lower end of the rubber seat 21 or the shaft box body 6. Further, a protruding piece 15c protruding from the pin 11 to the gap 22d may be provided.
Since the cylindrical laminated rubber 22 is located below the extension line at the center of the axle 4, the distance between the cylindrical laminated rubbers 22 and 22 can be reduced, and a cart having a small axle box can be obtained.

台車枠3に対する、軸箱体6の前後方向の大変位を抑制するために、図8に示す円筒積層ゴム22を用いてもよい。
図8において、円筒積層ゴム22の金属内筒22dには、突起部22iがある。突起部22iは、ピン11を中心にして車体1の前後方向に対向している間隙部22e、22eの位置にある。
突起部22iはその半径方向先端と積層ゴム22の金属外筒22fとの間には空間がある。
In order to suppress a large displacement in the front-rear direction of the axle box 6 with respect to the carriage frame 3, a cylindrical laminated rubber 22 shown in FIG. 8 may be used.
In FIG. 8, the metal inner cylinder 22d of the cylindrical laminated rubber 22 has a protrusion 22i. The protrusion 22 i is located at the positions of the gaps 22 e and 22 e facing the front and rear direction of the vehicle body 1 with the pin 11 as the center.
The protrusion 22 i has a space between its radial tip and the metal outer cylinder 22 f of the laminated rubber 22.

かかる構成により、台車枠3に対して、軸箱体6が大きく変位(台車枠3に対して軸箱体6が前後方向(X方向)に変位すること。)した時に、円筒積層ゴム22の金属外筒22fに突起部22iがあたるため、加減速時における円筒積層ゴム22の大変位を防止できる。
このため、円筒積層ゴム22の前後方向のばね定数が小さくなることによってゴム22bの変位量が大きくなることで発生する台車枠3、軸箱体6の間の大変位を抑制できる。
With this configuration, when the axle box 6 is greatly displaced with respect to the carriage frame 3 (the axle box 6 is displaced in the front-rear direction (X direction) relative to the carriage frame 3), the cylindrical laminated rubber 22 Since the protrusion 22i hits the metal outer cylinder 22f, large displacement of the cylindrical laminated rubber 22 during acceleration / deceleration can be prevented.
For this reason, the large displacement between the cart frame 3 and the shaft box body 6 that is generated when the amount of displacement of the rubber 22b is increased by reducing the spring constant in the longitudinal direction of the cylindrical laminated rubber 22 can be suppressed.

また、図9に示すように、突起部22iを金属外筒22hに設けた構成としても、同じ効果が得られる。   In addition, as shown in FIG. 9, the same effect can be obtained even if the protrusion 22i is provided on the metal outer cylinder 22h.

上記実施例では、台車枠3に対して、軸箱体6を、前後・左右方向へ弾性支持するのに、円筒積層ゴム22を使用した例であるが、円筒積層ゴム22の代わりに、図10に示す円筒ゴム26を用いてもよい。
図10の円筒ゴム26は、金属内筒26cと金属外筒26dとの間にゴム26bが加硫されており、ゴム26bはその円周方向において、欠けて、間隙部26eを構成している。
間隙部26eで、金属内筒26cの中心軸に対して軸直方向であるX方向、Y方向のばね定数を調整できる。
In the above embodiment, the cylindrical laminated rubber 22 is used to elastically support the axle box 6 in the front-rear and left-right directions with respect to the bogie frame 3, but instead of the cylindrical laminated rubber 22, FIG. The cylindrical rubber 26 shown in FIG.
In the cylindrical rubber 26 of FIG. 10, a rubber 26b is vulcanized between a metal inner cylinder 26c and a metal outer cylinder 26d, and the rubber 26b is chipped in the circumferential direction to form a gap portion 26e. .
With the gap portion 26e, it is possible to adjust the spring constants in the X direction and the Y direction that are perpendicular to the central axis of the metal inner cylinder 26c.

また、図11に示すように、円筒ゴム27を用いてもよい。
円筒ゴム27は、金属内筒27cと金属外筒27dとの間にゴム27bが加硫されている。
ゴム27の配合を調整することで、金属円筒27の中心軸に対して軸直方向のX方向、Y方向のばね定数を調整できる。
Further, as shown in FIG. 11, a cylindrical rubber 27 may be used.
In the cylindrical rubber 27, the rubber 27b is vulcanized between the metal inner cylinder 27c and the metal outer cylinder 27d.
By adjusting the blending of the rubber 27, the spring constants in the X direction and the Y direction in the direction perpendicular to the central axis of the metal cylinder 27 can be adjusted.

以下に、本発明の第6の実施形態を図12に基づいて説明する。
この実施例は、円筒積層ゴム22を車軸4の中心の水平方向に対して上方に設置したものであり、コイルばねの12の上部、すなわち、台車枠3とピン11の間に円筒積層ゴム22を設置している。簡単に言えば、図3に対して、12は上下が逆になっている。
図12において、ピン11は軸箱体6の穴に挿入している。18は、コイルばね12の上端と台車枠3とを接続するコイルばね座である。コイルばね座18は、図3のコイルばね座15に対応する。
圧入された円筒積層ゴム22の落下防止は、ゴム座21に設置した押え金22fで行なっている。
ゴム座21は、台車枠3の上部の面3aに載っている。
