 接合(溶接)部の開先加工が不要であり、溶接に伴う入熱に起因する歪取りなどの仕上げ工数を小さくするために、ボルトやリベット等の機械的締結手段によって6面体をなす構体や、構体の床面をなす台枠を組み立てる構造や方法が検討されている。 In order to reduce the number of finishing man-hours such as distortion removal caused by heat input due to welding, it is not necessary to bevel the joint (welded) part, and the structure that forms a hexahedron by mechanical fastening means such as bolts and rivets The structure and method for assembling the underframe that forms the floor of the structure are being studied.
 台枠を機械的締結手段で組み立てる場合、台枠の幅方向の両端部において車体長手方向に延びて設けられた側梁と、台枠の幅方向に沿って備えられる枕梁と、をボルトやリベットで接続した場合、これらリベットやボルトの頭部が、例えば、枕梁の長手方向の端部に当接される支持装置を構成する空気ばねと干渉するおそれがある。ボルトの頭部と空気ばねとの干渉を避けるためにボルトの頭部を収容できる座ぐり穴を枕梁に備える場合、枕梁の板厚を、座ぐり穴の深さと、ボルト座面に生じる荷重を負担できる厚さ、との和と同程度の厚さとしなければならない。枕梁の板厚が大きくなると、材料コストの増大だけでなく、台枠(構体)の重量が大きくなるなどの不都合が生じる可能性がある。 When assembling the underframe with mechanical fastening means, a side beam provided extending in the longitudinal direction of the vehicle body at both ends in the width direction of the underframe and a pillow beam provided along the width direction of the underframe are bolts or When connected with rivets, the heads of these rivets and bolts may interfere with, for example, an air spring that constitutes a support device that comes into contact with the longitudinal end of the pillow beam. In order to avoid interference between the bolt head and the air spring, if the pillow beam has a counterbore hole that can accommodate the bolt head, the thickness of the pillow beam is generated in the depth of the counterbore and the bolt seating surface. The thickness must be the same as the sum of the thickness that can bear the load. When the thickness of the pillow beam increases, there is a possibility that not only the material cost increases, but also the inconvenience such as the weight of the frame (structure) increases.
 本発明の目的は、枕梁と中梁と床材などが機械的締結手段によって構成された台枠を有す軌条車両構体において、台枠(枕梁)の下面に当接される空気ばねと、前述した機械的締結手段とが干渉することなく、さらに、材料コストおよび重量の増大を抑制できる軌条車両構体を提供することである。 An object of the present invention is to provide an air spring that is in contact with the lower surface of a base frame (pillow beam) in a rail vehicle structure having a base frame in which pillow beams, center beams, floor materials and the like are configured by mechanical fastening means. Another object of the present invention is to provide a rail vehicle structure that can suppress an increase in material cost and weight without interfering with the above-described mechanical fastening means.

The fastening portions 58 are arranged in two rows.
 枕梁15の下面(台車2が備えられる側の面)の長手方向の中央部には中心ピン受17が備えられ、中心ピン受17に隣接する態様で枕梁15の長手方向(図3の矢印110の方向)に沿って2つの空気ばね受16が備えられる。 A central pin receiver 17 is provided in the longitudinal center of the lower surface of the pillow beam 15 (the surface on which the carriage 2 is provided), and the longitudinal direction of the pillow beam 15 (in FIG. 3) is adjacent to the central pin receiver 17. Two air spring receivers 16 are provided along the direction of the arrow 110.
 台枠10の床部、側構体20、屋根構体40は、アルミニウム合金製の複数の中空押出形材を車体の長手方向に沿って並べ、隣接する中空押出形材の幅方向の接合端部同士を接合することにより構成される。側梁11は、車体の長手方向に沿ったアルミニウム合金製の中空押出形材であり、台枠10の幅方向の両端部に備えられる。端梁12は、アルミニウム合金製の板状部材と梁状部材を接合することにより構成され、台枠10の長手方向の両端部に備えられる。 The floor portion of the underframe 10, the side structure 20, and the roof structure 40 are formed by arranging a plurality of hollow extruded profiles made of aluminum alloy along the longitudinal direction of the vehicle body, and joining ends in the width direction of adjacent hollow extruded profiles. It is comprised by joining. The side beams 11 are hollow extruded shapes made of aluminum alloy along the longitudinal direction of the vehicle body, and are provided at both ends in the width direction of the underframe 10. The end beams 12 are configured by joining a plate-shaped member made of an aluminum alloy and a beam-shaped member, and are provided at both ends in the longitudinal direction of the underframe 10.
 中梁14(図3参照)は構体1の長手方向に沿って備えられるI型の断面形状を有するアルミニウム合金製押出形材であるが、その断面形状はI型に限らずU型、L型等任意形状でよい。なお、端梁12と中梁14とを鋼製としてもよく、この場合は、端梁12および中梁14と、台枠10のアルミニウム合金製の床部と、を機械的締結手段によって締結する。 The intermediate beam 14 (see FIG. 3) is an aluminum alloy extruded shape having an I-shaped cross-sectional shape provided along the longitudinal direction of the structure 1, but the cross-sectional shape is not limited to the I-shaped but U-shaped or L-shaped. Any arbitrary shape may be used. The end beam 12 and the middle beam 14 may be made of steel.

 端梁12、中梁14および枕梁15は、車両と車両とを連結する連結器を支持する部位であるとともに、構体1を支持する台車2との接続部でもある。これらの部位には、複数の車両からなる編成車両が起動して加速を経て定速走行に至る過程や、定速走行から減速を経て停止する過程などにおいて、連結器を介して引張り荷重や圧縮荷重が作用したり、台車2からの牽引力やブレーキ力が作用したりするため高い強度が要求される。 The end beam 12, the middle beam 14, and the pillow beam 15 are not only a portion that supports a coupler that links the vehicles, but also a connection portion with the carriage 2 that supports the structure 1. These parts are equipped with a tensile load and compression via a coupler in the process of starting a knitted vehicle consisting of a plurality of vehicles and accelerating to constant speed running or stopping from constant speed running through deceleration. A high strength is required because a load acts or a traction force or a braking force acts from the carriage 2.
 端梁12、中梁14および枕梁15は、機械的強度の高い鋼製の部材から構成されているため、アルミ合金製押出し形材からなる台枠10の一部である床部材や側梁11、中梁14などとの接合部において、溶接ではなくボルトやリベット等の機械的締結手段によって接合される。 Since the end beam 12, the middle beam 14, and the pillow beam 15 are made of steel members having high mechanical strength, floor members and side beams that are part of the frame 10 made of an aluminum alloy extruded shape. 11 and the intermediate beam 14 are joined by mechanical fastening means such as bolts and rivets instead of welding.
 図3と図4を参照して枕梁15の構成を説明する。枕梁15は、主要部を鋼製の板状部材51とし、板状部材51の台車2の側の面に複数の鋼製の幅方向梁52を備え、板状部材51の構体1の側の面に複数の鋼製の長手方向梁54を備えている。
 さらに、板状部材51が、2本のアルミニウム合金製の中梁14と交差する(当接する)部位には、構体1の長手方向に沿う態様で中梁14の幅とほぼ同じ幅寸法であり、且つ、枕梁15と交差する部位の枕梁15の幅方向(構体1の長手方向に沿う方向)寸法とほぼ同じ長さ寸法を有する鋼製の2枚の板材61が溶接されている。幅方向梁52と長手方向梁54と板材61は、溶接によって板状部材51に接合され、一体の枕梁15を構成している。
The configuration of the pillow beam 15 will be described with reference to FIGS. 3 and 4. The pillow beam 15 has a steel plate-like member 51 as a main part, and includes a plurality of steel width-direction beams 52 on the surface of the plate-like member 51 on the carriage 2 side. Are provided with a plurality of longitudinal steel beams 54 on the surface.
Further, the portion where the plate-like member 51 intersects (contacts) the two aluminum alloy intermediate beams 14 has a width dimension substantially the same as the width of the intermediate beam 14 along the longitudinal direction of the structure 1. In addition, two steel plate members 61 having substantially the same length dimension as the width direction (direction along the longitudinal direction of the structure 1) of the pillow beam 15 at a portion intersecting the pillow beam 15 are welded. The width direction beam 52, the longitudinal direction beam 54, and the plate material 61 are joined to the plate-like member 51 by welding to constitute an integral pillow beam 15.
 台枠10の下面と枕梁15を構成する板状部材51の上面の間には、十分な空間が存在しており、台枠10の下面に車体の長手方向に沿って、複数の配線や配管を束ねた配線・配管モジュール60が構体1の長手方向の端部から中央部に向かって枕梁15を貫通する態様で備えられている。
 特に、長手方向梁54は、構体1の長手方向に沿う態様で板状部材51に溶接されているため、配線・配管モジュール60およびモジュール化されていない配線・配管は、長手方向梁54と干渉することなく容易に、台枠1の下面側と板状部材51との間の空間に配設することができる。
There is sufficient space between the lower surface of the underframe 10 and the upper surface of the plate-like member 51 constituting the pillow beam 15, and a plurality of wires and A wiring / piping module 60 in which piping is bundled is provided in such a manner as to penetrate the pillow beam 15 from the longitudinal end of the structure 1 toward the center.
In particular, since the longitudinal beam 54 is welded to the plate-like member 51 in a manner along the longitudinal direction of the structure 1, the wiring / pipe module 60 and the non-modulated wiring / pipe interfere with the longitudinal beam 54. It can be easily arranged in the space between the lower surface side of the frame 1 and the plate-like member 51 without doing.
 板状部材51の空気ばね5(図1参照)が当接する部位には、空気ばね受16が備えられており、台車2と構体1との接続部となる枕梁15の長手方向の中央部には、中心ピン受17が備えられる。板状部材51の空気ばね受16が施工され、中心ピン受17が備えられる表面は、台車2と構体とを精度良く結合できるよう、台車2に備えられる部品の形状に合わせて平滑に仕上げられている。 An air spring receiver 16 is provided at a portion of the plate-like member 51 where the air spring 5 (see FIG. 1) abuts, and a central portion in the longitudinal direction of the pillow beam 15 that serves as a connecting portion between the carriage 2 and the structure 1. Is provided with a central pin receiver 17. The surface of the plate-like member 51 on which the air spring receiver 16 is constructed and the center pin receiver 17 is provided is finished smoothly according to the shape of the parts provided in the carriage 2 so that the carriage 2 and the structure can be combined with high accuracy. ing.
 図1に示すインナーフレーム台車は台車枠3が車輪の軌道中心側に備えられるため、台車枠3に備えられる空気ばね5同士の間隔L1(図4参照)が小さくなる傾向がある。このため、枕梁15の板状部材51に備えられる空気ばね受16の範囲内に、板状部材51と中梁14とを締結する2列に配列されたボルト締結部57,58が位置する場合がある。 In the inner frame bogie shown in FIG. 1, since the bogie frame 3 is provided on the track center side of the wheel, the interval L1 (see FIG. 4) between the air springs 5 provided in the bogie frame 3 tends to be small. Therefore, the bolt fastening portions 57 and 58 arranged in two rows for fastening the plate-like member 51 and the middle beam 14 are located within the range of the air spring receiver 16 provided in the plate-like member 51 of the pillow beam 15. There is a case.
 中梁14と板状部材51とを締結するボルト締結部57,58において、ボルト90の頭頂部が空気ばね受16と干渉することを防ぐため、板状部材51にボルト90を締結する工具の外径以上であり、且つ、ボルト90の頭頂部の高さ以上の深さの座ぐり穴が備えられている。座ぐり穴の深さが板状部材51の厚さと同じ程度の場合であっても、板状部材51の中梁14と重なる部位には板材61が溶接されて合計の板厚が増加されているので、座ぐり穴の深さを気にすることなく板状部材51に座ぐり穴を容易に施工することができる。 In the bolt fastening portions 57 and 58 that fasten the intermediate beam 14 and the plate-like member 51, a tool for fastening the bolt 90 to the plate-like member 51 in order to prevent the top of the bolt 90 from interfering with the air spring receiver 16. A counterbore having a diameter greater than or equal to the outer diameter and greater than or equal to the height of the top of the bolt 90 is provided. Even when the counterbore depth is about the same as the thickness of the plate-like member 51, the plate 61 is welded to the portion overlapping the middle beam 14 of the plate-like member 51 to increase the total plate thickness. Therefore, the counterbore can be easily constructed in the plate-like member 51 without worrying about the depth of the counterbore.
 さらに、中梁14と枕梁15との交差する部位に備えられる板材61の幅寸法は、中梁14の幅とほぼ同じであり、板材61の長さ寸法は枕梁15の幅とほぼ同じであるため、板状部材51全体の厚みを大きくする場合のような重量の増加を抑制するとともに、枕梁15をなす板状部材51の剛性を高めるとともにその強度の低下を抑制することができ、さらに、枕梁15の主要部である板状部材51に板材61を備えているため、板状部材51に座ぐり穴を容易に施工することができる効果を奏する。 Furthermore, the width dimension of the plate material 61 provided at the portion where the intermediate beam 14 and the pillow beam 15 intersect is substantially the same as the width of the intermediate beam 14, and the length dimension of the plate material 61 is substantially the same as the width of the pillow beam 15. Therefore, it is possible to suppress an increase in weight as in the case of increasing the thickness of the entire plate-like member 51, increase the rigidity of the plate-like member 51 forming the pillow beam 15, and suppress a decrease in the strength thereof. Furthermore, since the plate member 51 which is the main part of the pillow beam 15 is provided with the plate material 61, the counterbore hole can be easily constructed in the plate member 51.
 上記構成によって、機械的締結手段であるボルト90の頭部を収容できる座ぐり穴を枕梁15をなす板状部材51に備えることができるので、台車2に備えられる空気ばね5と、ボルト90の頭部とが干渉することを抑制できるとともに、台枠10に要求される強度を満足することができる。 With the above configuration, the plate-like member 51 forming the pillow beam 15 can be provided with a counterbore hole that can accommodate the head of the bolt 90 that is a mechanical fastening means, so the air spring 5 provided in the carriage 2 and the bolt 90 can be provided. Can be prevented from interfering with the head, and the strength required for the frame 10 can be satisfied.
 さらに、この構成によって、枕梁15を挟んで構体1の長手方向(図3参照、矢印100の方向)の端部から中央部にかけて枕梁15を貫通する態様で連続する配線・配管モジュール60を備えることができるので、配線や配管を小さい工数で構体1に備えることができる。 Furthermore, with this configuration, the wiring / piping module 60 that is continuous in a manner of penetrating the pillow beam 15 from the end in the longitudinal direction (see FIG. 3, the direction of the arrow 100) of the structure 1 across the pillow beam 15 to the center. Since it can be provided, the structure 1 can be provided with wiring and piping with a small man-hour.
 なお、実施例1ではインナーフレーム台車を備える構体1を例に挙げて説明したが、インナーフレーム台車を備えることに限定されず、ボルト締結部57,58が空気ばね受16の範囲に含まれる場合であれば、前述した効果を奏することができる。また、図4において機械的的結手段の一例としてボルト90をボルトとナットとから構成されることを図示しているが、ナットに代えて、板状のネジ座を備えても良いし、中梁14にネジ溝を有す部品を埋め込んでも良い。ナットを代替する構成は、後述する実施例2のボルト90,92においても適用できる。 In the first embodiment, the structure 1 including the inner frame carriage is described as an example. However, the structure 1 is not limited to including the inner frame carriage, and the bolt fastening portions 57 and 58 are included in the range of the air spring receiver 16. If it is, the effect mentioned above can be produced. 4 shows that the bolt 90 is composed of a bolt and a nut as an example of the mechanical connection means, but instead of the nut, a plate-like screw seat may be provided. A part having a thread groove may be embedded in the beam 14. The configuration replacing the nut can also be applied to the bolts 90 and 92 of Example 2 described later.
 図5と図6を参照して実施例2を説明する。実施例1で説明した構成等に関する記載と同じ構成に係る記載を省略し、実施例1と異なる構成や機能を中心に記載する。 Example 2 will be described with reference to FIGS. The description related to the same configuration as the description related to the configuration described in the first embodiment is omitted, and the configuration and functions different from those in the first embodiment are mainly described.
 図5は実施例2の軌条車両構体をなす台枠を下方から見た斜視図であり、図6は図5のc-c断面図である。 FIG. 5 is a perspective view of the base frame constituting the rail vehicle structure of Example 2 as viewed from below, and FIG. 6 is a cross-sectional view taken along the line cc of FIG.
 実施例1の場合と異なり、中梁14と配線・配管モジュール60との位置関係などの構体1の設計上の要因、あるいは、台車枠3に備えられる空気ばね5同士の間隔がL2となる等の台車2の設計上の要因によって、枕梁15の板状部材51に備えられる空気ばね受16の範囲内に、板状部材51と中梁14とを締結する2列に配列されたボルト締結部57,58の内のボルト締結部58のみが含まれる場合がある。 Unlike the case of the first embodiment, the design factors of the structure 1 such as the positional relationship between the intermediate beam 14 and the wiring / piping module 60, or the distance between the air springs 5 provided in the carriage frame 3 becomes L2. The bolt fastening arranged in two rows for fastening the plate-like member 51 and the middle beam 14 within the range of the air spring receiver 16 provided in the plate-like member 51 of the pillow beam 15 due to the design factors of the cart 2 Only the bolt fastening portion 58 of the portions 57 and 58 may be included.
 この場合、板状部材51の厚さを、ボルト締結部58に供されるボルト90(図4参照)の頭部を収容できる座ぐり穴を施工できる厚さとするとともに、座ぐり穴を設けないボルト締結部57に供されるボルト92の本数を、当該部位においてボルト90の本数より多くする。
 または、ボルト締結部58に供されるボルト90のサイズ(大きさ)をM16とし、ボルト締結部57に供されるボルト92のサイズをM22とする。M16のボルトサイズであればボルトの頭部がM22のそれに比較して小さいため、座ぐり穴の深さを小さくできるので、板状部材51の板厚(重量)の増加を抑制することができる。
In this case, the thickness of the plate-like member 51 is set to a thickness that allows a counterbore hole that can accommodate the head of the bolt 90 (see FIG. 4) provided to the bolt fastening portion 58 to be formed, and no counterbore hole is provided. The number of the bolts 92 provided to the bolt fastening portion 57 is made larger than the number of the bolts 90 at the corresponding part.
Alternatively, the size (size) of the bolt 90 provided for the bolt fastening portion 58 is M16, and the size of the bolt 92 provided for the bolt fastening portion 57 is M22. If the bolt size is M16, since the bolt head is smaller than that of M22, the depth of the counterbore can be reduced, so that an increase in the plate thickness (weight) of the plate-like member 51 can be suppressed. .
 この構成によって、板状部材51と中梁14との交差部(重なり部)の板状部材51に中梁14の幅とほぼ同じ幅の板材(実施例1の板材61に相当するもの)を貼り付けないでも、台枠10に要求される強度を満足することができる。 With this configuration, the plate member 51 at the intersection (overlapping portion) between the plate member 51 and the middle beam 14 is provided with a plate material having a width substantially equal to the width of the middle beam 14 (corresponding to the plate material 61 of the first embodiment). Even if it is not attached, the strength required for the underframe 10 can be satisfied.
 上記構成によって、枕梁15の重量の増加を抑制するとともに、枕梁15と中梁14とを強固に結合することができるので台枠10に要求される強度を満足することができる。 With the above configuration, an increase in the weight of the pillow beam 15 can be suppressed, and the pillow beam 15 and the intermediate beam 14 can be firmly coupled, so that the strength required for the frame 10 can be satisfied.
 さらに、台車2に備えられる空気ばね5と、ボルト90の頭部とが干渉することを抑制できる。 Furthermore, interference between the air spring 5 provided in the carriage 2 and the head of the bolt 90 can be suppressed.
 さらに、この構成であれば、枕梁15を挟んで構体1の長手方向(図3参照、矢印100の方向)の端部から中央部にかけて枕梁15を貫通する態様で連続する配線・配管モジュール60を備えることができるので、配線や配管を小さい工数で構体1に備えることができる。 Furthermore, with this configuration, a wiring / piping module that continues in a manner that penetrates the pillow beam 15 from the end in the longitudinal direction of the structure 1 (see FIG. 3, the direction of the arrow 100) to the center with the pillow beam 15 interposed therebetween. Since 60 can be provided, the structure 1 can be provided with wiring and piping with a small man-hour.
