Description

この発明は、高速鉄道車両の台車カバーに関するものであり、台車カバーの台車軸箱との対向部分を塞いだとき、急カーブ走行時の台車の旋回によって、台車カバーが台車と干渉しても支障を生じることがないような台車カバーの構造とし、これによって高速走行時の台車カバー開口部に起因する空気抵抗、騒音を低減することができるものである。   The present invention relates to a bogie cover for a high-speed railway vehicle. When the portion of the bogie cover facing the bogie axle box is closed, the bogie cover may interfere with the bogie by turning the bogie during a sharp turn. The structure of the carriage cover is such that the air resistance and noise caused by the opening of the carriage cover during high-speed traveling can be reduced.
高速鉄道車両においては、走行抵抗の低減、騒音低減等のために台車カバーでカバーしているが、レールの曲率半径が小さい場所においては、台車の旋回角度が大きくなり、台車の側への突出部、たとえば軸箱が台車カバーと干渉するために、台車の軸箱に対抗する部分が開口部になっている。
また、上記開口部による空気抵抗、騒音を防止するために台車カバーに開口部を設けないで台車を完全に覆っているものもある(実開平6−53356号マイクロフィルム)が、これは、台車カバーと台車とが干渉する恐れがなく、台車カバーと台車との干渉を全く問題にする必要のない車両を対象にしているものである。
ところで、新幹線から在来線に乗り入れる新在直通の高速鉄道車両においては、車体のサイズは在来線サイズとほぼ同じで、台車部分は新幹線サイズであるために、台車軸箱に対向する部分に開口部を設けないで台車カバーで完全に塞ぐことはできない。しかし通常の新幹線車両と同様に高速走行を行う走行条件は違いがないため、走行抵抗の低減、騒音低減等の台車カバーに対する要求は同一である。
実開平6−53356号マイクロフィルム
High-speed rail cars are covered with a bogie cover to reduce running resistance and noise, but in places where the radius of curvature of the rail is small, the turning angle of the bogie becomes large and protrudes toward the bogie side. In order for the part, for example, the axle box to interfere with the carriage cover, the portion facing the axle box of the carriage is an opening.
In addition, in order to prevent air resistance and noise due to the opening, there is a thing that covers the carriage completely without providing an opening in the carriage cover (No. 6-53356 microfilm). The present invention is intended for a vehicle that does not have the possibility of interference between the cover and the carriage and does not require any interference between the carriage cover and the carriage.
By the way, in the new direct high-speed railcar that enters the conventional line from the Shinkansen, the size of the car body is almost the same as the size of the conventional line, and the carriage part is the size of the Shinkansen. It cannot be completely covered with a bogie cover without providing an opening. However, since the driving conditions for high-speed driving are the same as for ordinary Shinkansen vehicles, the requirements for the bogie cover for reducing driving resistance and noise are the same.
Japanese Utility Model No. 6-53356 Microfilm
従来の新在直通の高速鉄道車両(以下これを、単に「高速鉄道車両」という)では、台車カバーに開口部があって台車が完全には覆われてはいないために、高速走行時の空気抵抗が高いだけでなく、開口部があることにより発生する騒音や台車部分からの騒音の遮蔽性能が下がるなどの不都合もある。このため、台車部分を台車カバーで完全に覆うことが要請されているが、未だ適切な対策は講じられていない。
ところで、高速鉄道車両において、台車カバーで台車を完全に覆うとき、実際に台車カバーが台車の軸箱の突出部分と干渉するのは、高速走行を行う本線の曲率半径は通常2500m以上であって、車体に対する台車の旋回角度が小さいため、特殊な条件でのことであり、その他の状況において干渉することはない。他方、低速で渡り線を通過するときや、操車場内などを走行する場合は、その線路では、最小曲率半径100mまでのカーブがあるところもあるため、車体に対する台車の旋回角度が大きく、台車カバーと台車の軸箱が干渉することがある。したがって、台車と台車カバー間の衝撃は比較的小さい。このような台車と台車カバーとの干渉の実態を分析することで、台車と干渉しても台車カバーが損傷しないように工夫すれば、台車を台車カバーで完全に覆うことが十分可能であり、特段の支障もないことが判明した。
なお、台車側において最も車体側面へ大きく接近していて、かつ台車に付属している部品の中で、干渉することを避けられる位置へ移動させることが困難な部分は、軸箱の先端部分である。
In conventional new direct high-speed railway vehicles (hereinafter simply referred to as “high-speed railway vehicles”), the carriage cover has an opening and the carriage is not completely covered. Not only is the resistance high, but there are also inconveniences such as a reduction in noise shielding performance due to noise generated from the opening and from the carriage. For this reason, although it is requested | required that a trolley | bogie part is completely covered with a trolley | bogie cover, an appropriate measure is not yet taken.
By the way, in a high-speed railway vehicle, when the carriage is completely covered with the carriage cover, the carriage cover actually interferes with the protruding portion of the axle box of the carriage. The radius of curvature of the main line for high-speed running is usually 2500 m or more. Because the turning angle of the carriage relative to the vehicle body is small, this is a special condition and there is no interference in other situations. On the other hand, when passing through a crossover at a low speed or traveling in a yard, there is a curve with a radius of curvature of up to 100m on the track. And the axle box of the cart may interfere with each other. Therefore, the impact between the carriage and the carriage cover is relatively small. By analyzing the actual situation of interference between the carriage and the carriage cover, it is possible to completely cover the carriage with the carriage cover if it is devised so that the carriage cover will not be damaged even if it interferes with the carriage. It was found that there was no particular hindrance.
The part that is closest to the side of the car body on the trolley side and is difficult to move to a position where interference can be avoided is the tip part of the axle box. is there.
他方、高速走行時には、列車すれ違い時や、トンネル突入時に発生する微気圧波により、側スカートと同様に台車カバーにも空気圧力がかかる。台車カバーの下端が解放されているから台車カバーにかかる上記圧力は比較的小さいけれども、その部分にかかる力は「圧力×面積」に比例するため変形を可及的に低減するためには、その受圧面積(外側表面積)はできるだけ小さい方が望ましい。
そこで、この発明は、高速鉄道車両の台車カバーについて、台車と干渉する部分を最小限の面積で可撓性を持たせることで、台車の旋回動作によって台車と干渉しても損傷することがないようにし、かつ、列車すれ違い時や、トンネル突入時の微気圧に対しては所要の剛性が確保されるように、台車カバーの機構・構造を工夫することをその課題とするものである。
On the other hand, during high-speed traveling, air pressure is also applied to the carriage cover as well as the side skirts due to micro-pressure waves generated when the trains pass each other or when the tunnel enters. Although the pressure applied to the carriage cover is relatively small because the lower end of the carriage cover is released, the force applied to that part is proportional to "pressure x area". The pressure receiving area (outer surface area) is desirably as small as possible.
In view of this, the present invention provides a carriage cover for a high-speed railway vehicle by providing a flexible portion with a minimum area that interferes with the carriage so that the carriage will not be damaged even if it interferes with the carriage due to the turning operation of the carriage. Thus, an object of the present invention is to devise the mechanism and structure of the bogie cover so that the required rigidity is ensured with respect to the micro atmospheric pressure at the time of passing the train or entering the tunnel.
〔解決手段〕
上記課題を解決するために講じた手段は、台車カバーを設けた高速鉄道車両について、次の(イ)〜(ハ)のとおりである。
(イ)台車の軸箱に対向する部分に設けられた台車カバー開口部に天然ゴムベースまたはEPDM(エチレンプロピレンゴム)等の合成ゴムなどによる可撓性弾性シート材料による成形品(以下「可撓性弾性材料成型品」という)を嵌め、当該可撓性弾性材料成型品を台車カバーに着脱自在に固定してあり、
(ロ)上記可撓性弾性材料成型品はその前方部分、後方部分および上部に蛇腹部を有し、当該蛇腹部の外側が台車カバー開口部の周縁に固定されており、
(ハ)台車が旋回してその軸箱外端が合成ゴム板に当接してこれを押すとき、上記蛇腹部が弾性変形して合成ゴム板の中央部分が車体外側へ押し出されるようになっていること。
[Solution]
Means taken to solve the above problems are as follows (a) to (c) for the high-speed railway vehicle provided with the bogie cover.
(A) A molded product made of a flexible elastic sheet material (hereinafter referred to as “flexible”) made of a natural rubber base or a synthetic rubber such as EPDM (ethylene propylene rubber) in a bogie cover opening provided in a portion facing the axle box of the bogie. A flexible elastic material molded product), and the flexible elastic material molded product is detachably fixed to the carriage cover.
(B) The flexible elastic material molded product has a bellows portion at a front portion, a rear portion and an upper portion thereof, and an outer side of the bellows portion is fixed to a peripheral edge of the carriage cover opening,
(C) When the bogie turns and the outer end of the axle box comes into contact with and pushes the synthetic rubber plate, the bellows portion is elastically deformed so that the central portion of the synthetic rubber plate is pushed out of the vehicle body. Being.
〔作用〕
天然ゴムベースまたはEPDM(エチレンプロピレンゴム)等の合成ゴムで必要な硬度や強度のある材料を選択し適宜調整できるので、必要な剛性、耐摩耗性を確保することができる。
台車カバーの台車軸箱に対向する部分に設けられた開口部は、可撓性弾性材料成型品によって塞がれているので、台車が大きく旋回したときに台車軸箱が可撓性弾性材料成型品に当接し、これを外方に押す。可撓性弾性材料成型品は、水平断面方向(前方部、後方部)の蛇腹部および垂直断面方向(上部)の蛇腹部が容易に弾性変形するので、その中央部が無理なく外方に押し出され、これが破損されることはない。
なお、上記水平断面形状の蛇腹部は凹凸の複数の波形である部分を意味するが、この波形の凹凸は、前後方向への伸縮性が高ければ一つでもよい。また上記垂直方向の蛇腹部は、単数の波型を意味しているが、より柔軟性を持たせる必要性があるときは、複数の波型でもよい。
[Action]
Since a material having the necessary hardness and strength can be selected and appropriately adjusted with a natural rubber base or a synthetic rubber such as EPDM (ethylene propylene rubber), necessary rigidity and wear resistance can be ensured.
The opening provided in the part of the carriage cover that faces the carriage axle box is closed by a flexible elastic material molded product, so that the carriage axle box is molded into a flexible elastic material when the carriage turns significantly. Touch the product and push it outward. The flexible elastic material molded product is easily elastically deformed in the horizontal cross section direction (front part, rear part) and the vertical cross section direction (upper part), so that the central part is pushed outwards without difficulty. This will not be damaged.
In addition, although the said bellows part of the horizontal cross-sectional shape means the part which is a several waveform of an unevenness | corrugation, if the stretchability to the front-back direction is high, this unevenness | corrugation may be one. In addition, the vertical bellows portion means a single wave shape, but a plurality of wave shapes may be used when more flexibility is required.
〔実施態様1〕
実施態様1は、台車軸箱の外端面に摺動抵抗の小さい摺動板を固定し、台車軸箱が台車カバーの可撓性弾性材料成型品と干渉するときは、この摺動板が可撓性弾性材料成型品の内側面に摺接するようにしたことである。
[Embodiment 1]
In Embodiment 1, a sliding plate having a low sliding resistance is fixed to the outer end surface of the bogie axle box. When the bogie axle box interferes with a flexible elastic material molded product of the bogie cover, this sliding plate is acceptable. That is, it is in sliding contact with the inner surface of the flexible elastic material molded product.
〔作用〕
台車軸箱の外端面を摺動抵抗の小さい摺動板でカバーしてあって、台車が旋回して軸箱が可撓性弾性材料成型品と干渉するときは摺動板が可撓性弾性材料成型品内面に圧接するので、軸箱が可撓性弾性材料成型品に対して滑らかに摺動し、可撓性弾性材料成型品内面の摩耗、損傷を防止することができる。
[Action]
When the outer end surface of the bogie axle box is covered with a sliding plate with low sliding resistance, and the bogie turns and the axle box interferes with the flexible elastic material molded product, the sliding plate is flexible elastic Since the material box is pressed against the inner surface of the molded product, the axle box can slide smoothly against the molded product of the flexible elastic material, and wear and damage to the inner surface of the molded product of the flexible elastic material can be prevented.
〔実施態様2〕
実施態様2は、上記解決手段における台車カバーを電磁波を通しやすく強度の高いグラスファイバーレインフォースドプラスチック(以下「GFRP」という)製とし、当該台車カバーの内側にLCX空中線アンテナを付設したことである。
なお同じ強度の高いファイバーレインフォースドプラスチックであっても、カーボンファイバーは導電性があるため、これを使用したカーボンファイバーレインフォースドプラスチック(一般的にはCFRPと言われる)は、強度が高いが電磁波に対する遮蔽性が高いので、内部にアンテナを配置するのに都合が悪い。他方、グラスファイバーは導電性がないため、これを使用したGFRPはこのような問題がない。
なお、LCX空中線アンテナは、新幹線の列車の側スカートの内側に収納されていて、レールに沿って敷設されたLCX(漏洩同軸ケーブル:固定アンテナ)との間で各種情報を確実に通信することができる通信用アンテナであって、従来周知のものである。
これまでの新幹線車両では、LCX空中線アンテナ10は列車の車両の内、必要な箇所に、車両の左右に、連続または一車両の二カ所に分けて配置されており(図6参照:図6は車両の前後二カ所に分けて配置された例)、LCX空中線アンテナ素子13を前後方向に一列に多数並べ、電気的に順次接続して構成される。
LCX空中線アンテナ10を配置する部分の側スカートは、金属製の側スカートに開口を設けて、その部分にカバーとしての電磁波を遮蔽せず、強度の高いGFRP製の板状のものを取り付けた構造であり、その内側にLCX空中線アンテナ素子13が着脱自在に固着されている。上記LCX空中線アンテナ素子13の構造や、側スカートへの取り付け構造は種々であり、従来周知の事項であるからその詳細な説明は省略するが、その一例の構造の概略は図7に示すようなものである。
[Embodiment 2]
Embodiment 2 is that the cart cover in the above solution is made of glass fiber reinforced plastic (hereinafter referred to as “GFRP”) that is easy to transmit electromagnetic waves and has high strength, and an LCX antenna antenna is attached to the inside of the cart cover. .
Even if it is a fiber-reinforced plastic with the same strength, carbon fiber is conductive, so the carbon-fiber-reinforced plastic using it (generally called CFRP) has high strength. Since the shielding property against electromagnetic waves is high, it is not convenient to place an antenna inside. On the other hand, since glass fiber has no electrical conductivity, GFRP using this does not have such a problem.
The LCX antenna is housed inside the side skirt of the Shinkansen train, and can reliably communicate various information with LCX (leakage coaxial cable: fixed antenna) laid along the rail. A communication antenna that can be used is known in the art.
In conventional Shinkansen vehicles, the LCX antenna 10 is arranged at necessary locations in the train vehicle, on the left and right sides of the vehicle, either continuously or divided into two locations of one vehicle (see FIG. 6: FIG. An example in which the vehicle is divided into two front and rear portions of the vehicle), and a large number of LCX antenna antenna elements 13 are arranged in a line in the front-rear direction and electrically connected sequentially.
The side skirt of the portion where the LCX antenna 10 is arranged has a structure in which an opening is formed in the metal side skirt, and a high-strength GFRP plate is attached to the portion without shielding electromagnetic waves as a cover. The LCX antenna antenna element 13 is detachably fixed to the inside thereof. The structure of the above-mentioned LCX antenna antenna element 13 and the mounting structure to the side skirt are various, and since it is a well-known matter in the past, detailed description thereof will be omitted, but the outline of the structure of an example is as shown in FIG. Is.
〔作用〕
解決手段における台車カバーの材質は適宜選択しうることであり、GFRP製としたことは課題解決と不可分に関連することではないが、電磁波を通しやすく強度の高いGFRP製とすることで、台車カバーの内側にLCX空中線アンテナを収納できるようになる。
従来は、LCX空中線アンテナは、金属製の側スカートの内部に設けられたが、金属そのままでは電磁波を通さないため、アンテナの使用目的上問題があるため、金属製の側スカート側の一部に開口をつくり、電磁波を通す目的でGFRP製の板状のものを取り付け、その内側にLCX空中線アンテナを収納していた。このために側スカートの構造が複雑であった。
この実施態様2のように台車カバーの主要部分をGFRP製として、その内側にLCX空中線アンテナを収納することで、一般部の側スカートはすべて同一の構造とすることが可能となる。
また、台車1カ所だけでは1両分のアンテナの長さが不足するため、1車両の前後の台車カバー内に、LCX空中線アンテナを設けることによって、従来例にある合成アンテナとすることも可能である。
[Action]
The material of the trolley cover in the solution means can be selected as appropriate, and the fact that it is made of GFRP is not inseparably related to the problem solving, but it is made of GFRP that is easy to transmit electromagnetic waves and has high strength. The LCX antenna antenna can be housed inside.
Conventionally, the LCX antenna was installed inside the metal side skirt, but the metal as it is does not transmit electromagnetic waves, so there is a problem for the purpose of use of the antenna. A plate made of GFRP was attached for the purpose of creating an opening and allowing electromagnetic waves to pass through, and an LCX antenna antenna was housed inside the plate. For this reason, the structure of the side skirt was complicated.
As in Embodiment 2, the main part of the carriage cover is made of GFRP, and the LCX antenna antenna is housed inside thereof, so that the side skirts of the general part can all have the same structure.
Also, since the length of the antenna for one car is insufficient at only one carriage, it is possible to provide a conventional synthetic antenna by providing an LCX antenna antenna in the carriage cover before and after one vehicle. is there.
この発明の効果は、上記解決手段1の作用から明らかであり、上記のとおりの機構、構造の台車カバーを用い、これで台車を完全に覆ったものであるから、台車カバーに設けられた開口部による空気抵抗、騒音が低減され、また、可撓性弾性材料成型品は台車軸箱との干渉で容易に弾性変形するので、上記干渉による衝撃はなく、可撓性弾性材料成型品の耐久性が高く、さらに、高速鉄道車両の高速走行時における台車カバーの振動が効果的に防止される。
また、この台車カバーの可撓性弾性材料成型品部分は台車軸箱に押されて変形するが、この変形は蛇腹部の伸縮によるものであるから、上記変形によって損傷することはなく、したがって、耐久性が高い。
The effect of the present invention is clear from the action of the above solution 1, and uses the carriage cover having the mechanism and structure as described above, and thus completely covers the carriage, so that the opening provided in the carriage cover Air resistance and noise due to the parts are reduced, and the flexible elastic material molded product is easily elastically deformed by interference with the bogie axle box, so there is no impact due to the interference, and the flexible elastic material molded product is durable. Moreover, the vibration of the carriage cover is effectively prevented when the high-speed railway vehicle is traveling at high speed.
In addition, the flexible elastic material molded part of the carriage cover is deformed by being pushed by the carriage axle box, but since this deformation is due to the expansion and contraction of the bellows part, it is not damaged by the deformation, and therefore High durability.
次いで、図面を参照して実施例を説明する。
〔実施例1〕
上半分が垂直で下半分が内側に傾斜した断面形状の側スカート1があり、台車を覆う部分が同形状の台車カバー2になっている。この台車カバー2の台車軸箱に対応した位置に前後の開口部2a,2aが設けられている(図1)。台車カバー2はGFRP製(グラスファイバーレインフォースプラスチック)であり、その開口部2a,2aに可撓性弾性材料成型品3,3が装着されている(図2,図3)。この可撓性弾性材料成型品3,3は、周囲が蛇腹状の形状であり、その下辺はフリーである。そして、この下辺以外の辺、すなわち前方、後方、上方の辺は開口部2a,2aの縁に固定螺子Aで着脱自在に固定されている(図4)。そして、図4に示すように、前方、後方の被固定部3x、及び上方の被固定部3yに固定ボルト用の穴3cがあり、被固定部3xの近傍に2つの波形状凹凸による蛇腹部3a、3aがあり、上方向の被固定部3yの近傍に1つの波形状の凹凸による蛇腹部3bがある。
Next, embodiments will be described with reference to the drawings.
[Example 1]
There is a side skirt 1 having a cross-sectional shape in which the upper half is vertical and the lower half is inclined inward, and a portion covering the carriage is a carriage cover 2 having the same shape. Front and rear openings 2a, 2a are provided at positions corresponding to the cart axle box of the cart cover 2 (FIG. 1). The carriage cover 2 is made of GFRP (glass fiber reinforcement plastic), and flexible elastic material molded products 3 and 3 are mounted in the openings 2a and 2a (FIGS. 2 and 3). The flexible elastic material molded products 3 and 3 have a bellows-like periphery, and the lower side is free. Sides other than the lower side, that is, the front side, the rear side, and the upper side are detachably fixed to the edges of the openings 2a and 2a by a fixing screw A (FIG. 4). As shown in FIG. 4, there are fixing bolt holes 3c in the front and rear fixed parts 3x and the upper fixed part 3y, and the bellows part is formed by two corrugations in the vicinity of the fixed part 3x. There are 3a and 3a, and there is a bellows part 3b with one corrugated unevenness in the vicinity of the fixed part 3y in the upward direction.
上記可撓性弾性材料成型品3は、この実施例では、厚さが15mmであり、蛇腹部3aの波の幅は100mm、高さは50mmで、蛇腹部3bの波の幅は50mm、高さは50mmである。これらの蛇腹部3a,3bの各寸法は、固定された状態で合成ゴム板3が所要の剛性を保ちつつ、車輪6の軸を支えている軸箱8に押されたとき、滑らかに伸縮する程度の剛性と柔軟性が具備されるように、材料の硬さ、強さ、合成ゴム板の大きさに応じて、適宜設計される。
そして、この可撓性弾性材料成型品3,3それ自体は、高速走行時の風圧によって振動することなく、かつ容易に破損することのない程度の強度を有することが必要である。
In this embodiment, the flexible elastic material molded product 3 has a thickness of 15 mm, the wave width of the bellows portion 3a is 100 mm, the height is 50 mm, and the wave width of the bellows portion 3b is 50 mm. The height is 50 mm. The dimensions of the bellows portions 3a and 3b are expanded and contracted smoothly when the synthetic rubber plate 3 is pushed into the axle box 8 supporting the shaft of the wheel 6 while maintaining the required rigidity. It is designed as appropriate according to the hardness and strength of the material and the size of the synthetic rubber plate so as to have a certain degree of rigidity and flexibility.
The flexible elastic material molded products 3 and 3 themselves need to have a strength that does not vibrate due to wind pressure during high-speed traveling and does not easily break.
急カーブを走行して台車4が大きく旋回すると、台車軸箱8が可撓性弾性材料成型品3の内側面に当接して、これを外方へ押し出す。この台車軸箱8によって可撓性弾性材料成型品(具体的には合成ゴム板)3が弾性変形して外方に膨らみ、台車軸箱8が内側に戻ると、可撓性弾性材料成型品3は弾性復元する。そして、台車軸箱8の押し力に対する可撓性弾性材料成型品3の弾性変形抵抗は比較的大きい。もし、台車軸箱8と可撓性弾性材料成型品3間の摩擦抵抗が大きいと、可撓性弾性材料成型品3に無理な力がかかり、可撓性弾性材料成型品3の耐久性を著しく害される。この実施例では、台車軸箱8の外端面に滑り板9を被せて止め捩子等の適宜の固着手段で着脱自在に固定している(図5参照)。この滑り板9は、図5(b)に示すような形状の鋼板製で、その摺動面sにフッ素樹脂フィルム等の低摩擦性樹脂をコーティングし、これによって上記の摩擦抵抗を低減している。   When the carriage 4 turns sharply while traveling on a sharp curve, the carriage axle box 8 comes into contact with the inner side surface of the flexible elastic material molded product 3 and pushes it outward. A flexible elastic material molded product (specifically, a synthetic rubber plate) 3 is elastically deformed and bulges outward by this cart axle box 8, and when the cart axle box 8 returns to the inside, a flexible elastic material molded product is obtained. 3 is elastically restored. And the elastic deformation resistance of the flexible elastic material molding 3 with respect to the pushing force of the cart axle box 8 is relatively large. If the frictional resistance between the bogie axle box 8 and the flexible elastic material molded product 3 is large, an excessive force is applied to the flexible elastic material molded product 3 to improve the durability of the flexible elastic material molded product 3. Seriously harmed. In this embodiment, a sliding plate 9 is put on the outer end surface of the bogie axle box 8 and is detachably fixed by appropriate fixing means such as a set screw (see FIG. 5). The sliding plate 9 is made of a steel plate having a shape as shown in FIG. 5B, and the sliding surface s is coated with a low friction resin such as a fluororesin film, thereby reducing the above-mentioned frictional resistance. Yes.
ところで、図示のように、車輪6の車軸中心は台車カバー2の折り目(垂直な上半分と内側に傾斜した下半分との境目の折り目)Lよりも下方にある(図1,図3参照)ので、台車4が大きく旋回すると、台車軸箱8の外端面の下端が台車カバー2の傾斜部に衝突する。以上のことからこの実施例は、台車カバー2の傾斜部を切り欠いて開口部を形成し、この開口部に可撓性弾性材料成型品3を装着している。このようにすることで上記開口部2aの大きさを可及的に小さくしている。
因みに、上記開口部2aの前後方向長さは約600mm、上下方向高さは約200mmであってその表面積は小さいから、空気圧力(風圧等)による可撓性弾性材料成型品3に対する負荷は極めて小さい。
By the way, as shown in the figure, the axle center of the wheel 6 is below the fold line (the fold line between the vertical upper half and the lower half inclined inward) L of the carriage cover 2 (see FIGS. 1 and 3). Therefore, when the cart 4 turns significantly, the lower end of the outer end surface of the cart axle box 8 collides with the inclined portion of the cart cover 2. From the above, in this embodiment, the inclined portion of the carriage cover 2 is cut out to form an opening, and the flexible elastic material molded product 3 is attached to the opening. By doing so, the size of the opening 2a is made as small as possible.
Incidentally, since the length of the opening 2a in the front-rear direction is about 600 mm, the height in the up-down direction is about 200 mm, and the surface area is small, the load on the flexible elastic material molded product 3 due to air pressure (wind pressure, etc.) is extremely high. small.
〔実施例2〕
次いで、上記実施例の台車カバー2にLCX空中線アンテナを付設した他の実施例2を説明する。
なお、LCX空中線アンテナは、新幹線の列車の側スカートの内側に収納されていて、レールに沿って敷設された固定アンテナとの間で各種情報を確実に通信することができる通信用アンテナであって、従来周知のものである。

[Example 2]
Next, another embodiment 2 in which an LCX antenna antenna is attached to the cart cover 2 of the above embodiment will be described.
The LCX antenna is a communication antenna that is housed inside the side skirt of a Shinkansen train and that can reliably communicate various information with a fixed antenna laid along the rail. Are well known in the art.
The LCX antenna antennas 10 are arranged on the left and right sides of the leading vehicle of the train (see FIG. 8), and a large number of LCX antenna antenna elements 13 are arranged in a line in the front-rear direction and electrically connected sequentially. The side skirt cover 14 (see FIGS. 6C and 7) where the LCX antenna antenna 10 is disposed is made of GFRP, and the LCX antenna antenna element 13 is detachably fixed to the inside thereof. The LCX antenna antenna element 13 has a variety of structures (see FIG. 7) and attachments to the side skirt cover 14, which are well known in the art, and will not be described in detail.
この実施例2では、台車カバー2がGFRP製であり、その垂直部の内側に多数のLCX空中線アンテナ素子13は着脱自在に取り付けられている(図9参照)。この例では、台車カバー2の前後方向の長さの関係から、一つの台車カバー2に2セットのLCX空中線アンテナ素子13を取り付けているが、LCX空中線アンテナ素子13が不足の場合は、先頭車両の前後の台車カバーにもLCX空中線アンテナ素子13を収納して、これらを合成器11を介して同軸ケーブル12で繋げばよい。
この実施例2では、側スカート1にはLCX中線アンテナ素子13を取り付けないから、先頭車両の側スカートについても、他の車両の側スカートと同じもの(例えばアルミ合金製)を用いることができる。全ての車両について側スカートを例えばアルミ合金製に統一できるので、コスト低減が計られる。
In the second embodiment, the carriage cover 2 is made of GFRP, and a large number of LCX antenna antenna elements 13 are detachably attached to the inside of the vertical portion (see FIG. 9). In this example, two sets of LCX antenna antenna elements 13 are attached to one carriage cover 2 because of the length of the carriage cover 2 in the front-rear direction, but if the LCX antenna antenna elements 13 are insufficient, the leading vehicle The LCX antenna antenna elements 13 may be housed in the front and rear cart covers, and these may be connected by the coaxial cable 12 via the combiner 11.
In the second embodiment, since the LCX mid-line antenna element 13 is not attached to the side skirt 1, the same side skirt as that of other vehicles (for example, aluminum alloy) can be used for the side skirt of the leading vehicle. . Since the side skirts can be made of, for example, an aluminum alloy for all vehicles, the cost can be reduced.
