Description

本発明は、鉄道車両用台車及び鉄道車両に関し、特に車両限界が小さく空気ばねの幅方向の端部が台車枠を構成する側梁の上面に載置される鉄道車両用台車及び鉄道車両に適用して好適なものである。   The present invention relates to a railway vehicle carriage and a railway vehicle, and more particularly, to a railway vehicle carriage and a railway vehicle in which a vehicle limit is small and an end in the width direction of an air spring is placed on an upper surface of a side beam constituting a carriage frame. Therefore, it is suitable.

鉄道車両用台車は、レール方向に沿って隔置される２本の側梁及びこれら側梁のレール方向の中央部を接続するとともに枕木方向に沿って配置される横梁から構成される台車枠と、２枚の車輪を車軸で締結した輪軸を回動可能に支持する軸箱支持装置とから構成される。   The bogie for a rail vehicle includes a bogie frame configured by connecting two side beams spaced along the rail direction and a lateral beam disposed along the sleeper direction while connecting the center portions of the side beams in the rail direction. An axle box support device that rotatably supports a wheel shaft in which two wheels are fastened by an axle.

乗客等が搭乗する箱状の車体は、台車枠の上面に設置される一対の空気ばねによって弾性支持される。通常、空気ばねは台車枠を構成する側梁のレール方向の中央部であり横梁との接続部の上面に、空気ばね座を介して設置される（特許文献１参照）。   A box-shaped vehicle body on which passengers or the like board is elastically supported by a pair of air springs installed on the upper surface of the carriage frame. Usually, an air spring is installed in the center part of the rail direction of the side beam which comprises a trolley | bogie frame, and the upper surface of a connection part with a cross beam via an air spring seat (refer patent document 1).

特許文献１に示されるように空気ばねは、鉄道車両用台車を構成する台車枠の上面に載置され、車体を弾性支持する。詳細には、側梁の長手方向の中央部を貫通する態様で横梁が設置されており、この横梁の両端部に配置される空気ばね台座の上部に空気ばねが載置される。   As shown in Patent Document 1, the air spring is placed on the upper surface of a bogie frame that constitutes a bogie for a railway vehicle, and elastically supports the vehicle body.

特開２００７−２６９１６６号公報JP 2007-269166 A

ところで台車周りの車両限界が小さく、空気ばねを車両限界の範囲内に配置した場合、空気ばねの中心部が台車枠の側梁よりも台車枠の幅方向の中心部寄りに位置するため、空気ばねを配置する部位を側梁に追設しなければならない。側梁の側面に空気ばねを受ける空気ばね受け部を追設する場合、別部品で製作した空気ばね受け部を側梁の側面に溶接したり、側梁に空気ばね受け部を一体で備えたりする方法が考えられる。   By the way, when the vehicle limit around the carriage is small and the air spring is arranged within the vehicle limit range, the center of the air spring is located closer to the center in the width direction of the carriage frame than the side beam of the carriage frame. The part where the spring is placed must be added to the side beam. When installing an air spring receiving part that receives an air spring on the side of the side beam, an air spring receiving part manufactured as a separate part is welded to the side of the side beam, or an air spring receiving part is integrally provided on the side beam. A way to do this is conceivable.

しかしこの場合、側梁は台車枠の骨格をなす強度部材であるため、空気ばねを受ける空気ばね受け部を側梁の側面に溶接すると、溶接部に高い仕上げ精度が要求され、製作工数が増大する。また側梁に一体成型で空気ばね受け部を備える場合、所定の形状に仕上げるための製作工数が大きくなる懸念があるため問題となる。   However, in this case, since the side beam is a strength member that forms the frame of the bogie frame, if the air spring receiving part that receives the air spring is welded to the side surface of the side beam, a high finishing accuracy is required for the welded part, and the number of manufacturing steps increases. To do. In addition, when the side beam is provided with an air spring receiving portion by integral molding, there is a concern that the number of manufacturing steps for finishing into a predetermined shape may be increased.

本発明は以上の点を考慮してなされたもので、製造コストを増大させることなく、空気ばねを側梁よりも台車枠の幅方向の中央部寄りに設置し得る鉄道車両用台車及び鉄道車両を提案する。   The present invention has been made in consideration of the above points, and the bogie for railway vehicles and the railway vehicle in which the air spring can be installed closer to the center in the width direction of the carriage frame than the side beams without increasing the manufacturing cost. Propose.

かかる課題を解決するために本発明においては、台車枠と、台車枠の上面に載置される空気ばねとを備える鉄道車両用台車において、台車枠は、レール方向に沿って隔置される２本の側梁と、側梁の中央部を枕木方向に沿って接続する２本の横梁と、横梁の中央部をレール方向に沿って接続する２本の第１つなぎ梁と、側梁、横梁及び第１つなぎ梁に囲まれた部分に設置される梁部材とを備え、空気ばねは、側梁と梁部材とに跨って設置される構成とした。   In order to solve such a problem, in the present invention, in a bogie for a railway vehicle including a bogie frame and an air spring mounted on the upper surface of the bogie frame, the bogie frame is spaced along the rail direction. Side beams, two horizontal beams connecting the central part of the side beams along the sleeper direction, two first connecting beams connecting the central part of the horizontal beam along the rail direction, side beams, and horizontal beams And a beam member installed in a portion surrounded by the first connecting beam, and the air spring is installed across the side beam and the beam member.

２本の横梁５４の幅方向１１０の中央部は、長手方向１００に沿って隔置される２本の第１つなぎ梁５６によって接続される。２本の横梁５４と２本の第１つなぎ梁５６とにより囲まれる空間には、台枠１０をなす枕梁１６から下方に下垂する中心ピン１８の先端部が挿入され、一本リンク（図示省略）等の牽引装置を介して鉄道車両用台車と車体とが接続される。   The central part of the two transverse beams 54 in the width direction 110 is connected by two first connecting beams 56 that are spaced along the longitudinal direction 100. In the space surrounded by the two transverse beams 54 and the two first connecting beams 56, the tip of the center pin 18 that hangs downward from the pillow beam 16 forming the underframe 10 is inserted, and a single link (shown) The railway vehicle carriage and the vehicle body are connected via a traction device such as (omitted).

（３）台車枠の構成
図３は、本実施の形態における台車枠の上面構成を示す。また図４は、図３の台車枠のＡ−Ａ断面構成を示す。鉄道車両が走行する路線によっては、レールに沿って敷設されるホーム等の構造部と鉄道車両との関係で車両限界８０の寸法Ｇ１に余裕がない場合がある。 (3) Configuration of Bogie Frame FIG. 3 shows an upper surface configuration of the bogie frame in the present embodiment. FIG. 4 shows an AA cross-sectional configuration of the bogie frame of FIG. Depending on the route on which the railway vehicle travels, there may be no allowance for the dimension G1 of the vehicle limit 80 due to the relation between the railway vehicle and a structural part such as a platform laid along the rail.

空気ばね３０の幅方向１１０の外縁の幅寸法Ｗ１を車両限界８０の幅寸法Ｇ１内に収めようとすると、空気ばね３０の中心間寸法Ｗ３が側梁５２の間隔Ｗ２よりも小さく、空気ばね３０の中心が側梁５２から外れて、車体の幅方向１１０の中央部寄りに位置する場合がある（図１参照）。   When the width dimension W1 of the outer edge in the width direction 110 of the air spring 30 is to be accommodated within the width dimension G1 of the vehicle limit 80, the center-to-center dimension W3 of the air spring 30 is smaller than the interval W2 of the side beams 52, May deviate from the side beam 52 and be located closer to the center in the width direction 110 of the vehicle body (see FIG. 1).

このため台車枠は、空気ばね３０を支持するために、側梁５２と第１つなぎ梁５６との間に、長手方向１００に沿って第２つなぎ梁５７を備える。空気ばね３０は、側梁５２の上面に設置される第１空気ばね座６０ａと、第２つなぎ梁５７の上面に設置される第２空気ばね座６０ｂとに跨る態様で設置される。   Therefore, the bogie frame includes a second connecting beam 57 along the longitudinal direction 100 between the side beam 52 and the first connecting beam 56 in order to support the air spring 30. The air spring 30 is installed in such a manner as to straddle the first air spring seat 60 a installed on the upper surface of the side beam 52 and the second air spring seat 60 b installed on the upper surface of the second connecting beam 57.

（４）本実施の形態による効果
以上のように本実施の形態によれば、空気ばね３０の中心間の寸法Ｗ３が、側梁５２の間隔Ｗ２よりも小さい場合であっても、重量を大きく増加させることなく空気ばね３０を台車枠５０の上面に載置することができる。さらに第２つなぎ梁５７を追設することにより、台車枠５０の剛性を高めることができる。 (4) Effects of this Embodiment As described above, according to this embodiment, even if the dimension W3 between the centers of the air springs 30 is smaller than the interval W2 between the side beams 52, the weight is increased. The air spring 30 can be placed on the upper surface of the carriage frame 50 without increasing it. Further, the rigidity of the carriage frame 50 can be increased by additionally providing the second connecting beam 57.

なお第２つなぎ梁５７の幅方向１１０の寸法ｂ（図４参照）を大きくしない場合、側梁５２から第２つなぎ梁５７に向けて空気ばね支持部５２ｃを追設してもよいし、図示はしないが、第２つなぎ梁５７の幅方向１１０の寸法ｂを大きくして、空気ばね支持部５２ｃを省略してもよい。   If the dimension b (see FIG. 4) of the second connecting beam 57 in the width direction 110 is not increased, an air spring support portion 52c may be additionally provided from the side beam 52 toward the second connecting beam 57. However, the dimension b in the width direction 110 of the second connecting beam 57 may be increased to omit the air spring support portion 52c.

また空気ばね３０を受ける支持部を、第２つなぎ梁５７、或いは、空気ばね支持部５２ｃにより構成することによって、側梁５２をＵ字断面を備えるＵ字鋼５２ａと、このＵ字鋼５２ａの開口部を塞ぐ底板５２ｂから構成することができる。この場合、厚板からなるこれらの部材を空気ばね３０をうける受部を側梁５２に一体に備えることに伴う複雑な３次元形状に加工する必要がないため、側梁５２（台車枠５０）の製作工数を低減することができる。   Moreover, the support part which receives the air spring 30 is comprised by the 2nd connecting beam 57 or the air spring support part 52c, The side beam 52 is provided with U-shaped steel 52a which has a U-shaped cross section, and this U-shaped steel 52a. It can be comprised from the baseplate 52b which plugs up an opening part. In this case, since it is not necessary to process these members made of thick plates into a complicated three-dimensional shape due to the fact that the receiving portion that receives the air spring 30 is provided integrally with the side beam 52, the side beam 52 (cart frame 50). The number of manufacturing steps can be reduced.

また第２つなぎ梁５７を備えることによって、側梁５２と横梁５４との接続部（溶接部）に生じる応力を低減することができるので、剛性が高く信頼性の高い鉄道車両用台車を提供することができる。   Further, by providing the second connecting beam 57, it is possible to reduce the stress generated in the connecting portion (welded portion) between the side beam 52 and the lateral beam 54, and therefore, a railway vehicle bogie having high rigidity and high reliability is provided. be able to.

（５）他の実施の形態
図５は、他の鉄道車両用台車の台車枠の上面構成を示す。横梁５４の幅方向１１０の端部に備えられるブレーキ装置取り付け座と、第２つなぎ梁５７とが一体に構成され、第２つなぎ梁５７の長手方向１００の両端部にブレーキ装置取り付け座５７ａを備える点で、上記の実施の形態と異なる。 (5) Other Embodiments FIG. 5 shows a top configuration of a bogie frame of another bogie for a railway vehicle. The brake device mounting seat provided at the end of the transverse beam 54 in the width direction 110 and the second connecting beam 57 are integrally formed, and the brake device mounting seat 57a is provided at both ends in the longitudinal direction 100 of the second connecting beam 57. This is different from the above-described embodiment.

この構成によって、台車枠を構成する部品点数や溶接線長さを低減することができるので、製造コストの小さい鉄道車両用台車を提供することできる。   With this configuration, since the number of parts and the length of the weld line constituting the bogie frame can be reduced, it is possible to provide a bogie for a rail vehicle with a low manufacturing cost.

図６は、更に他の鉄道車両用台車の台車枠の上面構成を示す。第２つなぎ梁５７（図３参照）に代えて、側梁５２及び第１つなぎ梁５６を幅方向に沿う方向に配設される第２横梁５５で接続して構成される点で、上記の実施の形態と異なる。第２横梁５５は、側梁５２の長手方向１００の中央部の側面と第１つなぎ梁５６の長手方向１００の中央部側面とを接続している。   FIG. 6 shows a top structure of a bogie frame of still another bogie for a railway vehicle. Instead of the second connecting beam 57 (see FIG. 3), the side beam 52 and the first connecting beam 56 are connected by the second transverse beam 55 arranged in the direction along the width direction. Different from the embodiment. The second lateral beam 55 connects the side surface of the central portion in the longitudinal direction 100 of the side beam 52 and the central side surface of the first connecting beam 56 in the longitudinal direction 100.

この第２横梁５５と側梁５２に跨る態様で空気ばね座６０が備えられており、空気ばね座６０の上面に空気ばね３０が載置され、車体を弾性支持する。この構成によって、台車枠を構成する部品点数や溶接線長さを低減することができるので、製造コストの小さい鉄道車両用台車を提供することできる。   An air spring seat 60 is provided so as to straddle the second lateral beam 55 and the side beam 52, and the air spring 30 is placed on the upper surface of the air spring seat 60 to elastically support the vehicle body. With this configuration, since the number of parts and the length of the weld line constituting the bogie frame can be reduced, it is possible to provide a bogie for a rail vehicle with a low manufacturing cost.
