このように形成した妻構体50は、スライド中梁43に繋がる端梁26及び上面板55に結合され、前記出入台13の部分に設けられた前記クラッシャブルゾーン40を介して前記車体11の端部に設けられる。このクラッシャブルゾーン40の上下には、下部スライド部41と上部スライド部42とが設けられている。   The wife structure 50 formed in this way is coupled to the end beam 26 and the upper surface plate 55 connected to the middle slide beam 43, and is connected to the end of the vehicle body 11 via the crushable zone 40 provided in the entrance / exit 13 portion. Provided in the section. A lower slide portion 41 and an upper slide portion 42 are provided above and below the crushable zone 40.

下部スライド部41は、端梁26の幅方向中央部に接続され、前記枕梁22の方向に向かって水平方向に平面視略T字状に突設したスライド中梁43を、枕梁22から車端方向に向かって水平方向に突出したガイド中梁44に対して支持部材43a、44aを介して車体前後方向にスライド可能に設けるとともに、あらかじめ設定された荷重を超えたときに破断するように設計された下部ヒューズ部材にて連結して形成されている。   The lower slide portion 41 is connected to a central portion in the width direction of the end beam 26, and a slide middle beam 43 projecting in a substantially T shape in a plan view in a horizontal direction toward the pillow beam 22 from the pillow beam 22. It is provided so as to be slidable in the longitudinal direction of the vehicle body via the support members 43a and 44a with respect to the guide middle beam 44 protruding in the horizontal direction toward the vehicle end direction, and to be broken when a preset load is exceeded. It is formed by connecting with the designed lower fuse member.

上部スライド部42は、上部補強梁56の両端部から扉枠部33の鴨居部33aに沿って水平に突出したスライド棒47と、戸袋部37の上部に設けられたガイド枠48とを備えている。スライド棒47は、ガイド枠48に対して車体前後方向にスライド可能に設けられるとともに、前記下部スライド部41と同様に、あらかじめ設定された荷重を超えたときに破断するように設計された上部ヒューズ部材にてスライド棒47とガイド枠48とが連結されている。   The upper slide part 42 includes a slide bar 47 that protrudes horizontally from both ends of the upper reinforcing beam 56 along the head part 33 a of the door frame part 33, and a guide frame 48 provided on the upper part of the door pocket part 37.

The slide bar 47 is provided so as to be slidable in the longitudinal direction of the vehicle body with respect to the guide frame 48 and, like the lower slide part 41, is an upper fuse designed to break when a preset load is exceeded. The slide bar 47 and the guide frame 48 are connected by a member.

前記各ヒューズ部材は、あらかじめ設定した引張荷重及び圧縮荷重に耐える強度を有する部材であって、複数の鉄道車両を連結器59により連結して使用する際に加わる通常の引張荷重や圧縮荷重では永久変形又は破断せず、衝突によってあらかじめ設定した荷重を超える過大な荷重が作用したときに破断するような強度に設定されている。すなわち、過大な荷重が作用したときにヒューズ部材が破断することにより、スライド中梁43及びスライド棒47が、ガイド中梁44及びガイド枠48に対してそれぞれスライド可能な状態となり、台枠20内に設置した複数の衝撃吸収部材45を押しつぶすことでエネルギー吸収を行う。   Each of the fuse members is a member having a strength capable of withstanding a preset tensile load and a compressive load, and is permanent with a normal tensile load and a compressive load applied when a plurality of railway vehicles are connected by a connector 59 and used. The strength is set such that it does not deform or break, but breaks when an excessive load exceeding a preset load is applied by collision. That is, when an excessive load is applied, the fuse member breaks, so that the slide middle beam 43 and the slide bar 47 can slide with respect to the guide middle beam 44 and the guide frame 48, respectively. Energy absorption is performed by crushing the plurality of shock absorbing members 45 installed in the.

また、出入台部分に配置されている各部材の強度、例えば、前記扉枠部33、床板17、屋根構体60の出入台部分における強度は、前記ヒューズ部材の強度より低い強度に設定されており、過大な荷重が加わってヒューズ部材が破断する際には、扉枠部33、床板17及び屋根構体60の出入台部分も、前記ヒューズ部材の破断と同時に変形するように設定されている。   In addition, the strength of each member arranged in the entrance / exit part, for example, the strength in the entrance / exit part of the door frame portion 33, the floor plate 17, and the roof structure 60 is set to be lower than the strength of the fuse member. When an excessive load is applied and the fuse member breaks, the door frame portion 33, the floor plate 17 and the entrance / exit portions of the roof structure 60 are also set to be deformed simultaneously with the breakage of the fuse member.

衝撃吸収部材45は、例えば、断面正方形の同一形状の角パイプからなる4本の長尺衝撃吸収体45aと、該長尺衝撃吸収体45aの長さに比べて長さが短い2本の短尺衝撃吸収体45bとを、各衝撃吸収体45a,45bの軸線を互いに平行して組み合わせたものを使用することができる。各衝撃吸収体45a,45bの基端は、取付板45cに一体的に接合されており、該取付板45cを枕梁22やガイド中梁44の端面に取り付け、各衝撃吸収体45a,45bの軸線を車体前後方向に向けて配置している。各衝撃吸収体45a,45bの先端には、対向する二組の対向面の内の一組の対向面の先端縁に切欠部45dがそれぞれ設けられており、各衝撃吸収体45a,45bは、各切欠部45d同士が隣接しないように組み合わされている。   The shock absorbing member 45 includes, for example, four long shock absorbers 45a made of square pipes having the same shape having a square cross section, and two short lengths shorter than the length of the long shock absorber 45a. A combination of the shock absorber 45b and the axes of the shock absorbers 45a and 45b in parallel with each other can be used. The base ends of the shock absorbers 45a and 45b are integrally joined to the mounting plate 45c. The mounting plate 45c is attached to the end surfaces of the pillow beam 22 and the guide middle beam 44, and the shock absorbers 45a and 45b The axis is arranged in the vehicle longitudinal direction. At the tip of each shock absorber 45a, 45b, a notch 45d is provided at the tip edge of one of the opposing faces of the two opposing faces, and each shock absorber 45a, 45b The notches 45d are combined so as not to be adjacent to each other.

このように形成した衝撃吸収部材45は、衝突時には、最初に長尺衝撃吸収体45aの切欠部45dを設けていない対向縁が衝撃を受けて変形し、続いて短尺衝撃吸収体45bの切欠部45dを設けていない対向縁が衝撃を受けて変形を開始する。各衝撃吸収体45a、45bの変形は、隣接する衝撃吸収体の壁面に相互に影響を与えながら基端側に向かって連続して繰り返される。これにより、各衝撃吸収体45a、45bの壁面を連続的に蛇腹状に座屈させて衝撃を吸収することができる。また、複数の衝撃吸収体を幅方向及び高さ方向に配置して接合しているので、衝撃吸収部材45の曲げ剛性が高まり、中間部で折れ曲がることを防止できるので、衝突エネルギーを確実に吸収することができる。   In the impact absorbing member 45 formed in this way, at the time of a collision, the opposing edge that is not provided with the notched portion 45d of the long impact absorber 45a is first deformed by receiving an impact, and then the notched portion of the short impact absorber 45b. The opposing edge not provided with 45d receives an impact and starts to deform. The deformation of each shock absorber 45a, 45b is continuously repeated toward the base end side while mutually affecting the wall surfaces of the adjacent shock absorbers. Thereby, the wall surface of each impact-absorbing body 45a, 45b can be continuously buckled in a bellows shape, and an impact can be absorbed. In addition, since a plurality of shock absorbers are arranged and joined in the width direction and the height direction, the bending rigidity of the shock absorbing member 45 is increased, and it is possible to prevent bending at the middle portion, so that collision energy is reliably absorbed. can do.

このように、妻構体50の下部を接合した端梁26は、スライド中梁43とガイド中梁44とにより形成された下部スライド部41によって車体前後方向にスライド可能に保持され、妻構体50の上部に設けられた上部補強梁56は、車体両側に配置したスライド棒47とガイド枠48とにより形成された上部スライド部42によって車体前後方向にスライド可能に保持された状態にそれぞれ形成されており、さらに、端梁26と上部補強梁56とは、妻柱53及び隅柱54によって強固に連結され、妻柱53及び隅柱54の下部には、妻柱53及び隅柱54の剛性を高めるための柱補強部材57,58をそれぞれ設けているので、端梁26、上部補強梁56、妻柱53及び隅柱54を強固に接合するとともに、妻柱53及び隅柱54を端梁26や上部補強梁56の前面に配置することによって妻構体50が強固に枠組みされた状態になる。   Thus, the end beam 26 joined to the lower portion of the wife structure 50 is held by the lower slide portion 41 formed by the slide middle beam 43 and the guide middle beam 44 so as to be slidable in the longitudinal direction of the vehicle body. The upper reinforcing beam 56 provided at the upper part is formed so as to be slidably held in the longitudinal direction of the vehicle body by the upper slide part 42 formed by the slide rod 47 and the guide frame 48 arranged on both sides of the vehicle body. Further, the end beam 26 and the upper reinforcing beam 56 are firmly connected to each other by the end post 53 and the corner post 54, and the rigidity of the end post 53 and the end post 54 is increased below the end post 53 and the end post 54. Since the column reinforcing members 57 and 58 are provided for the purpose, the end beam 26, the upper reinforcing beam 56, the end column 53 and the corner column 54 are firmly joined, and the end column 53 and the end column 54 are connected to the end beam. A state where the end structure 50 is rigidly framework by placing in front of 6 and the upper reinforcing beam 56.

これにより、妻構体50に正面方向から大きな外力が作用した場合でも、妻構体50に斜め方向から大きな外力が作用した場合でも、妻構体50の一部に大きな外力が作用した場合でも、妻構体50の全体で外力を受けることができ、下部スライド部41及び上部スライド部42によって妻構体50を車体後方に向けて平行に移動させることができるので、妻構体50が客室14に向かって倒れることを防止できる。   As a result, even when a large external force is applied to the wife structure 50 from the front direction, a large external force is applied to the wife structure 50 from an oblique direction, or a large external force is applied to a part of the wife structure 50, the wife structure. 50 can receive external force and the lower slide part 41 and the upper slide part 42 can move the wife structure 50 in parallel toward the rear of the vehicle body, so that the wife structure 50 falls toward the passenger compartment 14. Can be prevented.

また、上部補強梁56や端梁26の外面に妻柱53及び隅柱54を接合しているので、妻柱53や隅柱54に作用する外力を上部補強梁56や端梁26に確実に伝達することができる。さらに、隅柱補強部材58の下部は、下端を突出片26aの上面に接合し、下端部側面を端梁26の外面に接合しているので、隅柱補強部材58を端梁26の上面に立設した場合に比べて隅柱補強部材58と端梁26との接合強度を向上させることができ、妻面への外力を妻構体50の全体及び端梁26に効果的に伝達することができる。   Further, since the end column 53 and the corner column 54 are joined to the outer surfaces of the upper reinforcement beam 56 and the end beam 26, the external force acting on the end column 53 and the corner column 54 is reliably applied to the upper reinforcement beam 56 and the end beam 26. Can communicate. Furthermore, since the lower part of the corner column reinforcing member 58 has its lower end joined to the upper surface of the protruding piece 26a and its lower end side surface joined to the outer surface of the end beam 26, the corner column reinforcing member 58 is connected to the upper surface of the end beam 26. The joint strength between the corner column reinforcing member 58 and the end beam 26 can be improved as compared with the case of standing upright, and the external force on the end face can be effectively transmitted to the entire end structure 50 and the end beam 26. it can.

したがって、妻構体50に作用する外力の作用方向や外力の作用位置に関係なく、クラッシャブルゾーンとなる出入台13の部分を変形させながら妻構体50を車体後方に向かって平行に移動させることができるので、衝撃吸収部材45では、各衝撃吸収体45a,45bの軸線方向に外力が作用することになる。これにより、各衝撃吸収体45a,45bを前述のように確実に座屈変形させることができ、衝撃吸収部材45による外力の吸収効果を十分に発揮させることができる。このように、車端部に設けた出入台13の部分だけを変形させて衝突エネルギーを吸収することにより、客室14を保護することができる。   Therefore, regardless of the direction of the external force acting on the wife structure 50 and the position where the external force is applied, the wife structure 50 can be moved in parallel toward the rear of the vehicle body while deforming the portion of the entrance / exit 13 serving as a crushable zone. Therefore, in the shock absorbing member 45, an external force acts in the axial direction of the shock absorbing bodies 45a and 45b. Thereby, each shock absorber 45a, 45b can be reliably buckled and deformed as described above, and the effect of absorbing external force by the shock absorbing member 45 can be sufficiently exhibited. Thus, the passenger cabin 14 can be protected by deforming only the part of the entrance / exit 13 provided at the vehicle end portion and absorbing the collision energy.

さらに、側構体30の側柱31の下端を台枠20の側梁21に設けられた突出片21aの上面部に接合し、側柱31の下部内面を側梁21の外面部21bに接合しているので、車体側方から側構体30に加わる外力を、側柱31の下端部を介して側梁21の外面部21bで支持することができる。したがって、側柱31の下端を側梁21の上面に接合した場合に比べて側柱31と側梁21との接合強度が向上し、台枠20と側構体30とを強固に接合することができるので、車体の側面部分に大きな外力が加わっても側構体30が車体内側に向けて変形することを抑えることができる。また、上方から屋根構体60に加わる外力も、側柱31を介して側梁21の突出片21aで支持することができるので、上方からの外力によって屋根構体60が車体内側に向けて変形することを抑えることができる。   Further, the lower end of the side column 31 of the side structure 30 is joined to the upper surface portion of the protruding piece 21 a provided on the side beam 21 of the underframe 20, and the lower inner surface of the side column 31 is joined to the outer surface portion 21 b of the side beam 21. Therefore, the external force applied to the side structure 30 from the side of the vehicle body can be supported by the outer surface portion 21 b of the side beam 21 via the lower end portion of the side column 31. Therefore, compared with the case where the lower end of the side column 31 is bonded to the upper surface of the side beam 21, the bonding strength between the side column 31 and the side beam 21 is improved, and the underframe 20 and the side structure 30 can be bonded firmly. Therefore, even if a large external force is applied to the side surface portion of the vehicle body, the side structure 30 can be prevented from being deformed toward the vehicle body inner side. Further, the external force applied to the roof structure 60 from above can also be supported by the protruding piece 21a of the side beam 21 via the side pillar 31, so that the roof structure 60 is deformed toward the inside of the vehicle body by the external force from above. Can be suppressed.

また、妻柱53及び隅柱54と各柱補強部材57,58との組み付けを、妻柱53及び隅柱54の車体内部側に設けた開口53a,54aを通して各柱補強部材57,58を妻柱53及び隅柱54の内部に挿入して行うことにより、妻構体50を水平方向に移動させて組み付けることが可能となる。これにより、妻柱53及び隅柱54を、様々な車体断面の妻構体50に先組みした状態で妻構体50と台枠20とを結合することが可能となり、各柱補強部材57,58と妻柱53及び隅柱54との組み付けを容易に行うことができる。さらに、妻柱53や隅柱54が傾斜している妻構体にも対応することが可能となる。   Further, the column reinforcement members 57 and 58 are assembled to the column pillars 57 and 58 through the openings 53a and 54a provided on the inner side of the vehicle body 53 and the corner columns 54. By inserting it into the pillars 53 and the corner pillars 54, it is possible to move and assemble the wife structure 50 in the horizontal direction. Accordingly, the wife structure 50 and the base frame 20 can be coupled in a state in which the wife pillar 53 and the corner pillar 54 are pre-assembled to the wife structure 50 having various vehicle cross-sections. Assembly with the end pillar 53 and the corner post 54 can be easily performed. Furthermore, it is possible to deal with a wife structure in which the wife pillar 53 and the corner pillar 54 are inclined.

なお、前頭部の車体では、出入台13の部分に運転台や乗務員室が設けられ、妻面には、幌や標識灯などが設けられる。また、妻柱53は、貫通扉18の有無や妻面窓19の形状に応じて適宜な位置に設けることができ、1本であってもよい。さらに、衝撃吸収部材45の構造や上部接続部材49の構造も適宜な構造を採用することができる。 In the forehead car body, a driver's cab and a crew room are provided at the entrance 13 and a wob is provided with a hood, a marker lamp, and the like. Further, the end pillar 53 can be provided at an appropriate position according to the presence or absence of the through door 18 and the shape of the end face window 19, and may be one. Furthermore, the structure of the structure and the upper portion connecting member 49 of the shock absorbing member 45 can also be employed an appropriate structure.
