Description

【０００１】
【発明の属する技術分野】
本発明は、鉄道車両の車体に係り、軽合金製中空形材によって構成される車体に好適である。
【０００２】
【従来の技術】
鉄道車両において、衝突の際、乗客に加わる衝撃力を緩和することが求められている。特開平１１−３０１４７６号公報，特開平６−２１１１３３号公報のように、複数の車体を直列に連結してなる編成車両において、先頭の車体の先頭部の台枠に壊れ易い構造などの衝撃吸収機構を設け、衝撃吸収し、乗客への衝撃を緩和するようにしている。
【０００３】
実公昭５７−５６９２９号公報のように、車体の台枠の端部には隣接する車体に連結する連結器がある。このため、台枠の端部の下面には強度部材が設けられ、強固に構成されている。
【０００４】
特開平２−２４６８６３号公報のように、車体は軽合金性の中空形材で構成している。中空形材はその押し出し方向を車体の長手方向に向けている。
【０００５】
【発明が解決しようとする課題】
中空形材で構成した車体において、衝撃緩和機能を持たせる構造とするためには、次のような課題がある。
【０００６】
（１）衝撃緩和機構を設置する車体の端部の長さが短く、車体の内部および床下の空間部が狭く制限された構造においては、衝撃緩和機構を設置することができない。
【０００７】
（２）中空形材は、従来の薄板構造の部材に比較して高さが大きく、その面内剛性および面外曲げ剛性が高いため、強度上は有利な構造であるが、衝撃力を緩和する緩衝特性の面では不利な構造である。
【０００８】
（３）車体の端部は強固であり、この部分に衝撃緩和機構を組み込むのは困難である。
【０００９】
また、編成車両の先頭部に衝撃吸収機構を組み込むのみでなく、各車体にも衝撃吸収機構を組み込むことが望ましい。これを組み込む位置は車体の端部である。
【００１０】
本発明の目的は、基本的に中空形材で構成した車体において、衝撃緩和機構を提供することにある。
【００１１】
【課題を解決するための手段】
上記目的は、中空形材で構成された鉄道車両の車体において、車体の端部の中空形材に緩衝孔を設けることにより達成される。
【００１２】
【発明の実施の形態】
図１において、中空形材４０を示していない。しかし、複数の中空形材４０があることを想定して、該中空形材４０の下方の部材３５，３６，３７を点線で示している。図２，図９，図１２は、中空形材４０の特定位置への緩衝孔の配置を示すために、中空形材４０の縦断面図と中空形材４０の平面図とを合成して示している。
【００１３】
本発明の一実施例を図１ないし図８によって説明する。車体は、側面を構成する側構体１０，屋根構体２０，床を構成する台枠３０等から構成している。側構体１０，屋根構体２０，台枠３０はそれぞれ複数の中空形材を接合して構成している。中空形材は軽合金製の押し出し型材で、その押し出し方向（すなわち、長手方向）を車体の長手方向に向けている。Ｗは窓である。
【００１４】
台枠３０は、複数の中空形材４０と、その両側の大きな側梁３１とからなる。さらに、車体の端部の下面には連結器を接続するための強度部材が設置されている。この強度部材は、車体の幅方向に向けた枕梁３５と、枕梁３５から車体の端部に設置した２つの中梁３６，３６と、中梁３６の端部に設置した端梁３９とからなる。２つの中梁３６，３６は部材３７で連結されている。中梁３６は車体の幅方向において中央付近にある、２つの中梁３６，３６の間に連結器が配置される。連結器は部材３７に連結されるので、この部分の中梁３６，３６の高さは大きくなっている。これら部材の相互間は溶接で接合されている。また、中空形材４０に溶接されている。
【００１５】
車体の端部の台枠３０の中空形材４０の上下の面板４１，４２には多数の孔
５１，５２を開けている。中空形材４０は２枚の面板４１，４２と、この面板
４１，４２を接続する斜材４３とからなる。斜材４３，４３はトラスを構成するように配置されている。中空形材４０と中空形材４０を接合する部分は２つの面板４１，４２を接合する板が傾斜していなくて、面板４１，４２に直交している場合がある。面板４１，４２には孔５１，５２があるので、衝撃が加わった際、孔５１，５２の周囲の面板４１，４２等が座屈し、衝撃を吸収し、緩和する。
【００１６】
孔５１の位置を説明する。孔５１は上面の面板４１にある。上面の面板４１においては、トラスの１つの辺である面板４１に、押し出し方向に沿って所定間隔で長方形の孔５１ｂを開けている。孔５１ｂは押し出し方向の方が短い。隣接するトラスの辺である面板４１にも孔５１ｃを開けている。孔５１ｃは押し出し方向に沿って所定間隔で配置している。孔５１ｃの形状は孔５１ｂと同一である。孔５１ｃは隣接する孔５１ｂと孔５１ｂとの間にある。すなわち、孔５１（孔５１ｂ，５１ｃを総称して言う。）を千鳥状に配置している。
【００１７】
下面の板４２にも孔５１と同様に孔５２を開けている。孔５２は孔５１ｂと孔５１ｃの間にある。なお、孔５１，５２の形状は楕円形でもよい。
【００１８】
例えば、トラスのピッチ（中空形材の幅方向のトラスのピッチ）は１３０mm、孔５１，５２の大きさは８０mm×３０mm、孔５１ｂ（５１ｃ）のピッチは３００mm程度である。
【００１９】
下面の面板４２は車体の下面に面しているので、水や雪にさらされる。このため、面板４２には孔５２を覆う板５９を下方から固定している。板５９は孔５２の部分を下方に突出させている。
【００２０】
また、側構体１０，屋根構体２０を構成する中空形材の端部に孔５１を設けている。孔５１は水や雪を考慮して、車体の内面側のみに設ける。孔５１の大きさ，個数等は、側構体１０，屋根構体２０の強度，衝撃力等を考慮して定める。
【００２１】
孔５１，５２を設ける位置は、先頭車両の先頭部，中間車両の前後端部である。個々は運転席や便所の位置となることが多い。
【００２２】
かかる構成によれば、車体の端部に衝撃が加わると、孔５１，５２の部分で中空形材は座屈を生じ、衝撃を緩和する。台枠３０は強固に設けられているので、上下の面板４１，４２に孔を開け、座屈を生じ易くしている。
【００２３】
衝撃荷重をより多く分担するのは、枕梁３５，部材３７、および２つの中梁３６，３６で囲まれた第１の領域と、連結器を連結する部材３７付近３０Ｘと枕梁３５の端部付近（側梁３１側）３０Ｙを接続する線よりも枕梁３５側の３角形状の第２の領域である。この３角形状の領域は中梁３６の側面にあるので、２つある。第１の領域と第２の領域に孔５１，５２を重点的に設ける。例えば、図１のように、前記領域の孔５１、および後述する孔５２の長手方向および幅方向のピッチを小さくしたり、孔５１，５２の大きさを小さくする。領域外にも孔５１，５２を設けてもよい。
【００２４】
図９から図１１の他の実施例を説明する。この実施例は緩衝能力をより大きくするためのものである。孔５１ｄ，５２ｄはトラスの頂点に設ける。トラスの頂点および付近の面板４１，４２および斜材４３，４３を切削で除去して設けている。孔５１ｄ，５２ｄの深さ（面板４１の外面から孔の位置の斜材の上端までの距離）は例えば８mm程度である。
【００２５】
孔５１ｄ，孔５２ｄのそれぞれは中空形材の長手方向に沿って所定間隔で設けている。孔５１ｄ同士は並列である。孔５２ｄ同士は並列である。孔５１ｄと孔５２ｄの関係は千鳥状に配置している。
【００２６】
これによれば、トラスの頂点の斜材４３が無いので、より座屈をしやすくなり、より衝撃力を緩和できる。
【００２７】
図１２から図１４の実施例を説明する。下面の面板４２には孔が無い。図１から図１１までの実施例では上下の面板４１，４２に孔５１，５２を設けているので、車外側の孔５２を覆おう板５９を必要としている。図１２の実施例は板５９を除くことを目的としている。上面（車内側）の面板４１に下面の面板４２の孔に相当する孔５１ｅ（第１の孔）を設けている。孔５１ｅは孔５１ｄ（第１の孔）があるトラスに隣接するトラスの辺の面板４１に設けている。孔５１ｅは孔５１ｄがあるトラスに隣接するトラスの頂点を中心にして設けている。孔５１ｅの下方（車外の面板４２側）にある斜材４３，４３を除いている。斜材４３を除く大きさは孔５１ｄに相当する。面板４２には孔を開けていない。
【００２８】
図９の実施例において、孔５１ｄと孔５２ｄの関係は、中空形材の押し出し方向に沿って並列に設けることができる。図１２の実施例においても同様である。図２の実施例においても、孔５１を並列にでき、孔５１と孔５２とを並列にできる。並列にした方が衝撃力をより緩和できる。
【００２９】
面板４１，４２に孔を設けないで、孔５１，５２に相当する位置の面板４１，４２を削って板厚を薄くする。また、薄くした部分を中空形材の内側に向けてプレスすることが考えられる。
【００３０】
中空形材の長手方向を車体の長手方向に対して直交する方向に配置した場合において、この中空形材に孔５１，５２を設ける場合は、斜材４３にも孔を設ける。
【００３１】
本発明の技術範囲は、特許請求の範囲の各請求項に記載の文言あるいは課題を解決するための手段の項に記載の文言に限定されず、当業者がそれから容易に置き換えられる範囲にも及ぶものである。
【００３２】
【発明の効果】
本発明によれば、車体の内部および床下などに特別の部材を追加することなく、中空押出し形材の一部を加工するだけで衝撃を緩和できる車体構造を実現することができる。これにより、車端構造部の長さや各構造部の寸法が制限されている場合、中空押出し形材で構成した現状の車体構造をほとんど変えることなく、突然の列車衝突事故時に際しても乗客，乗員へ与える衝撃力を最小限に緩和し、安全性の高い鉄道車両を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle body of a railway vehicle, and is suitable for a vehicle body constituted by a light alloy hollow shape material.
[0002]
[Prior art]
In a railway vehicle, it is required to reduce the impact force applied to passengers in the event of a collision. In a knitted vehicle in which a plurality of vehicle bodies are connected in series as in JP-A-11-301476 and JP-A-6-21133, shock absorption such as a structure that is easily broken by the frame at the top of the top body A mechanism is provided to absorb the impact and reduce the impact on the passenger.
[0003]
As disclosed in Japanese Utility Model Publication No. 57-56929, there is a connector for connecting to an adjacent vehicle body at the end of the frame of the vehicle body. For this reason, a strength member is provided on the lower surface of the end portion of the underframe and is firmly constructed.
[0004]
As disclosed in JP-A-2-246863, the vehicle body is formed of a light alloy hollow shape. The hollow shape member is oriented in the longitudinal direction of the vehicle body.
[0005]
[Problems to be solved by the invention]
In order to provide a structure having an impact mitigating function in a vehicle body constituted by a hollow member, there are the following problems.
[0006]
(1) In a structure in which the length of the end of the vehicle body where the impact mitigation mechanism is installed is short and the space inside the vehicle body and the space below the floor are limited, the impact mitigation mechanism cannot be installed.
[0007]
(2) The hollow shape is advantageous in terms of strength due to its large height and high in-plane rigidity and out-of-plane bending rigidity compared to the conventional thin plate structure members, but reduces the impact force. This is a disadvantageous structure in terms of buffer characteristics.
[0008]
(3) The end portion of the vehicle body is strong, and it is difficult to incorporate an impact relaxation mechanism in this portion.
[0009]
Further, it is desirable not only to incorporate the shock absorbing mechanism at the head of the knitted vehicle, but also to incorporate the shock absorbing mechanism into each vehicle body. The position where this is incorporated is the end of the vehicle body.
[0010]
An object of the present invention is to provide an impact mitigation mechanism in a vehicle body basically composed of a hollow member.
[0011]
[Means for Solving the Problems]
The above-mentioned object is achieved by providing a buffer hole in the hollow member at the end of the vehicle body in a railway vehicle body constituted by a hollow member.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, the hollow shape member 40 is not shown. However, assuming that there are a plurality of hollow members 40, members 35, 36, and 37 below the hollow members 40 are indicated by dotted lines. 2, 9, and 12, a vertical sectional view of the hollow shape 40 and a plan view of the hollow shape 40 are shown in order to show the arrangement of the buffer holes at a specific position of the hollow shape 40. ing.
[0013]
An embodiment of the present invention will be described with reference to FIGS. The vehicle body is composed of a side structure 10 that constitutes a side surface, a roof structure 20, a frame 30 that constitutes a floor, and the like. The side structure 10, the roof structure 20, and the underframe 30 are each configured by joining a plurality of hollow shapes. The hollow material is an extruded die made of a light alloy, and its extrusion direction (that is, the longitudinal direction) is directed to the longitudinal direction of the vehicle body. W is a window.
[0014]
The underframe 30 includes a plurality of hollow members 40 and large side beams 31 on both sides thereof. Further, a strength member for connecting the coupler is installed on the lower surface of the end portion of the vehicle body. This strength member includes a pillow beam 35 directed in the width direction of the vehicle body, two middle beams 36 and 36 installed from the pillow beam 35 to the end of the vehicle body, and an end beam 39 installed at the end of the middle beam 36. Consists of. The two middle beams 36 and 36 are connected by a member 37 . The intermediate beam 36 is located near the center in the width direction of the vehicle body, and a coupler is disposed between the two intermediate beams 36 and 36. Since the coupler is coupled to the member 37 , the height of the middle beams 36, 36 in this portion is increased. These members are joined together by welding. Further, it is welded to the hollow shape member 40.
[0015]
A large number of holes 51 and 52 are formed in the upper and lower face plates 41 and 42 of the hollow shape member 40 of the frame 30 at the end of the vehicle body. The hollow shape member 40 includes two face plates 41 and 42 and a diagonal member 43 connecting the face plates 41 and 42. The diagonal members 43, 43 are arranged to constitute a truss. In the portion where the hollow shape member 40 and the hollow shape member 40 are joined, the plates that join the two face plates 41 and 42 may not be inclined and may be orthogonal to the face plates 41 and 42. Since the face plates 41 and 42 have holes 51 and 52, when an impact is applied, the face plates 41 and 42 around the holes 51 and 52 buckle, and the impact is absorbed and relaxed.
[0016]
The position of the hole 51 will be described. The hole 51 is in the upper face plate 41. In the upper face plate 41, rectangular holes 51b are formed in the face plate 41, which is one side of the truss, at predetermined intervals along the extrusion direction. The hole 51b is shorter in the extrusion direction. A hole 51c is also formed in the face plate 41 which is the side of the adjacent truss. The holes 51c are arranged at predetermined intervals along the extrusion direction. The shape of the hole 51c is the same as that of the hole 51b. The hole 51c is located between the adjacent holes 51b and 51b. That is, the holes 51 (the holes 51b and 51c are collectively referred to) are arranged in a staggered manner.
[0017]
Similarly to the hole 51, a hole 52 is formed in the lower plate 42. The hole 52 is between the hole 51b and the hole 51c. The holes 51 and 52 may be oval in shape.
[0018]
For example, the truss pitch (the truss pitch in the width direction of the hollow member) is 130 mm, the sizes of the holes 51 and 52 are 80 mm × 30 mm, and the pitch of the holes 51b (51c) is about 300 mm.
[0019]
Since the lower face plate 42 faces the lower face of the vehicle body, it is exposed to water and snow. For this reason, a plate 59 covering the hole 52 is fixed to the face plate 42 from below. The plate 59 projects the hole 52 downward.
[0020]
Moreover, the hole 51 is provided in the edge part of the hollow shape material which comprises the side structure 10 and the roof structure 20. As shown in FIG. The hole 51 is provided only on the inner surface side of the vehicle body in consideration of water and snow. The size, the number, and the like of the holes 51 are determined in consideration of the strength and impact force of the side structure 10 and the roof structure 20.
[0021]
The positions where the holes 51 and 52 are provided are the leading portion of the leading vehicle and the front and rear end portions of the intermediate vehicle. Individuals often have driver seats or toilets.
[0022]
According to such a configuration, when an impact is applied to the end portion of the vehicle body, the hollow shape member buckles at the portions of the holes 51 and 52, and the impact is mitigated. Since the frame 30 is firmly provided, holes are formed in the upper and lower face plates 41 and 42 to easily cause buckling.
[0023]
The impact load is more shared by the first region surrounded by the pillow beam 35, the member 37 , and the two middle beams 36, 36, the vicinity of the member 37 connecting the coupler, and the end of the pillow beam 35. This is a triangle-shaped second region on the side of the pillow beam 35 from the line connecting the vicinity (the side beam 31 side) 30Y. Since this triangular region is on the side surface of the middle beam 36, there are two. The holes 51 and 52 are intensively provided in the first region and the second region. For example, as shown in FIG. 1, the pitches in the longitudinal direction and the width direction of the holes 51 in the region and the holes 52 described later are reduced, or the sizes of the holes 51 and 52 are reduced. Holes 51 and 52 may be provided outside the region.
[0024]
Another embodiment of FIGS. 9 to 11 will be described. This embodiment is for increasing the buffer capacity. The holes 51d and 52d are provided at the apex of the truss. The face plates 41, 42 and the diagonal members 43, 43 near the apex and the vicinity of the truss are provided by cutting. The depth of the holes 51d and 52d (the distance from the outer surface of the face plate 41 to the upper end of the diagonal material at the hole position) is, for example, about 8 mm.
[0025]
Each of the hole 51d and the hole 52d is provided at a predetermined interval along the longitudinal direction of the hollow shape member. The holes 51d are in parallel. The holes 52d are in parallel. The relationship between the holes 51d and the holes 52d is staggered.
[0026]
According to this, since there is no diagonal material 43 at the apex of the truss, it becomes easier to buckle and the impact force can be more relaxed.
[0027]
The embodiment of FIGS. 12 to 14 will be described. The bottom face plate 42 has no holes. In the embodiment shown in FIGS. 1 to 11, since the holes 51 and 52 are provided in the upper and lower face plates 41 and 42, a plate 59 for covering the hole 52 outside the vehicle is required. The embodiment of FIG. 12 is intended to remove the plate 59. A hole 51e (first hole) corresponding to the hole of the lower face plate 42 is provided in the upper face (inner side) face plate 41. The hole 51e is provided in the face plate 41 on the side of the truss adjacent to the truss having the hole 51d (first hole) . The hole 51e is provided centering on the apex of the truss adjacent to the truss with the hole 51d. The diagonal members 43, 43 below the hole 51e (on the side of the face plate 42 outside the vehicle) are excluded. The size excluding the diagonal material 43 corresponds to the hole 51d. The face plate 42 is not perforated.
[0028]
In the embodiment of FIG. 9, the relationship between the holes 51d and the holes 52d can be provided in parallel along the extrusion direction of the hollow profile. The same applies to the embodiment of FIG. In the embodiment of FIG. 2 as well, the holes 51 can be arranged in parallel, and the holes 51 and 52 can be arranged in parallel. The impact force can be mitigated more in parallel.
[0029]
Without providing holes in the face plates 41, 42, the face plates 41, 42 at positions corresponding to the holes 51, 52 are shaved to reduce the plate thickness. It is also conceivable to press the thinned part toward the inside of the hollow shape.
[0030]
In the case where the hollow member is arranged in the direction orthogonal to the longitudinal direction of the vehicle body, when the holes 51 and 52 are provided in the hollow member, the diagonal member 43 is also provided with a hole.
[0031]
The technical scope of the present invention is not limited to the language described in each claim of the claims or the language described in the means for solving the problem, and extends to a range easily replaced by those skilled in the art. Is.
[0032]
【The invention's effect】
According to the present invention, it is possible to realize a vehicle body structure that can alleviate an impact only by processing a part of a hollow extruded shape member without adding a special member inside the vehicle body or under the floor. As a result, when the length of the vehicle end structure and the dimensions of each structure are limited, passengers and passengers can be used even in the event of a sudden train collision, with almost no change to the current vehicle body structure made up of hollow extruded profiles. The impact force applied to the vehicle can be reduced to a minimum, and a highly safe railway vehicle can be provided.
