Description

本発明は、鉄道車両用ストッパに係り、詳しくは、鉄道車両の台車に対する過剰な横揺れを規制すべく、前記鉄道車両側の第１部材と前記台車側の第２部材との何れか一方との間に横方向の間隙を有する状態で前記第１部材と前記第２部材との何れか他方に支持される鉄道車両用ストッパに関するものである。   The present invention relates to a railway vehicle stopper, and more particularly, to restrict excessive rolling of the railway vehicle relative to the carriage, either the first member on the railway vehicle side or the second member on the carriage side. The present invention relates to a railway vehicle stopper that is supported by either one of the first member and the second member with a lateral gap therebetween.

この種の鉄道車両用ストッパとしては、特許文献１や特許文献２で開示されるものが知られている。特許文献１のものは、車体（１２）から下方に突設される左右一対の支持腕（１４）の左右間に、台車枠（８）に立設されているストッパ受け（１８）を配置してあり、各支持腕（１４）には積層ゴム構造のストッパゴム（１７）が装備されている。特許文献２のものは、車体側のストッパブラケット（５）と左右方向で対峙する台車側の取付ブラケット（６）に、ゴム塊でなる左右ストッパ（７）が取付けられている。   As this type of railcar stopper, those disclosed in Patent Literature 1 and Patent Literature 2 are known. In Patent Document 1, a stopper receiver (18) standing on a carriage frame (8) is disposed between the left and right of a pair of left and right support arms (14) projecting downward from a vehicle body (12). Each support arm (14) is equipped with a laminated rubber-structured stopper rubber (17). In Patent Document 2, a left and right stopper (7) made of a rubber lump is attached to a carriage side mounting bracket (6) that confronts the vehicle body side stopper bracket (5) in the left and right direction.

上記いずれの従来技術によるストッパでも、その支持部への取付手段としてはストッパの金属基板にボルトをねじ込み溶接して一体的に固定し、それらボルトを支持部に通してナット止めする構造のものであった。このストッパへのボルト一体化構造では、別途にボルト・ナットを用意して組付ける場合に比べて、部品点数を少なくして取り扱い性に優れるとともに、ナットを締付ける操作だけで済むものであって組付性も良好である。
In any of the above-described conventional stoppers, as a mounting means to the support portion, a bolt is screwed and welded to the metal substrate of the stopper and fixed integrally, and these bolts are passed through the support portion and fixed with nuts. there were. This bolt-integrated structure with the stopper reduces the number of parts and improves handling compared with the case of separately preparing bolts and nuts and assembling them. Adhesiveness is also good.

ところが、鉄道車両用ストッパを国内だけでなく国外においても鉄道車両に組付ける場合には少なからず問題の出ることが分かってきた。即ち、国内においては厳守されるナットの締付トルク管理が十分に為されず、締付過ぎによるネジ山の潰れやボルト折損等の不具合が生じ易いとのことである。これを部品側において解決するには、締め過ぎに耐える高強度ボルトを用いることが考えられるが、これを用いるには新たな問題がある。   However, it has been found that there are not a few problems when the railcar stoppers are assembled not only in Japan but also overseas. That is, the tightening torque management of nuts that are strictly observed in Japan is not sufficiently performed, and problems such as screw thread collapse and bolt breakage due to excessive tightening are likely to occur. In order to solve this on the part side, it is conceivable to use a high-strength bolt that can withstand overtightening, but there is a new problem in using this.

即ち、別部品となる高強度ボルトを用いて支持部にボルト止めさせる手段では、例えば、特許文献３に開示される防振ゴムストッパ（図１参照）のように、金属基板（硬質基板）にボルトを通す孔を開けておき、高強度ボルトを金属基板から支持部に向けて通してナット止めするようになる。その締付操作時にスパナ等でボルト頭の回り止めを行う必要があるが、実際ではボルト頭の回り止め操作スペースが取れない場合が多い。かといって、高強度ボルトの通し方向を反対にしてナット止めする操作はさらに難しい。このように、鉄道車両用ストッパのボルト止め構造にはさらなる改善の余地が残されているものであった。   That is, with a means for bolting the support portion using a high-strength bolt that is a separate component, for example, a vibration-proof rubber stopper (see FIG. 1) disclosed in Patent Document 3 is attached to a metal substrate (hard substrate). A hole through which the bolt is passed is made, and a high-strength bolt is passed from the metal substrate toward the support portion to be fastened with a nut. During the tightening operation, it is necessary to prevent the bolt head from rotating with a spanner or the like. However, the operation of fastening the nut with the high-strength bolt passing in the opposite direction is even more difficult. Thus, there is still room for improvement in the bolting structure of the railcar stopper.

本発明の目的は、前記実情に鑑みての構造工夫により、スパナ等によるボルト頭の回り止め操作を不要としながら高強度ボルトを用いての支持部への取付けが行えるように、ボルト頭の回り止め構造部を合理的に有するように改善された鉄道車両用ストッパを提供する点にある。   The object of the present invention is to improve the structure of the bolt head around the bolt head so that the bolt head can be attached to the support portion using a high-strength bolt while eliminating the need to stop the bolt head with a spanner or the like. An object of the present invention is to provide an improved railcar stopper that has a stop structure rationally.

以下に、本発明による鉄道車両用ストッパの実施の形態を、図面を参照しながら説明する。   Embodiments of a railway vehicle stopper according to the present invention will be described below with reference to the drawings.

〔実施例１〕
鉄道車両用ストッパＡは、図１，図２に示すように、側面視で上向きコ字状を為す硬質基板１と、この硬質基板１に加硫接着等によって一体化されるゴム（弾性材の一例）製のクッション２とを有して平面視で矩形を呈するものに構成されている。図１において前後中心Ｃの右側には、挿通孔５にボルト８が挿入されて、ボルト頭８ａがボルト回り止め部６に嵌合した状態を描いてある。尚、ボルト８としては高強度ボルトを用いることができる。 [Example 1]
As shown in FIGS. 1 and 2, the railcar stopper A includes a hard substrate 1 having an upward U-shape in a side view and rubber (an elastic material) integrated with the hard substrate 1 by vulcanization adhesion or the like. An example) It has the cushion 2 made from, and is comprised by what shows a rectangle by planar view. In FIG. 1, a state in which the bolt 8 is inserted into the insertion hole 5 and the bolt head 8 a is fitted to the bolt detent portion 6 is depicted on the right side of the front-rear center C. Note that a high-strength bolt can be used as the bolt 8.

硬質基板１は、平らな基板主部３と、基板主部３の左右端において長手方向に延びる状態で***形成される一対の側壁部４と、左右の中心で前後端部にそれぞれに形成される一対の挿通孔５と、各挿通孔５の前後方向の内側及び左右に対する立設壁となる状態のボルト回り止め部６と、を一体的に有する金属材によって構成されている。一対の挿通孔５，５は、前後中心Ｃに関して対称となるように左右中心Ｐ上における端部に配備されている。ボルト回り止め部６は、ボルト頭８ａに外接する二面幅部６Ａ，６Ａと、それらどうしを繋ぐ連結壁部６Ｂとを有して、挿通孔５の軸心Ｘ方向視で外側に向けて開放される姿勢のコ字状を呈する壁体として基板主部３から***形成されている。つまり、各挿通孔５，５に配置される一対のボルト回り止め部６，６は、互いに背を向ける状態で硬質基板１に一体形成によって設けられている。
The hard substrate 1 is formed on a flat substrate main portion 3, a pair of side wall portions 4 formed so as to extend in the longitudinal direction at the left and right ends of the substrate main portion 3, and the front and rear end portions at the left and right centers, respectively. A pair of insertion holes 5 and a bolt detent portion 6 in a state of being a standing wall with respect to the inner side in the front-rear direction and the left and right of each insertion hole 5 are made of a metal material. The pair of insertion holes 5, 5 are arranged at the ends on the left-right center P so as to be symmetric with respect to the front-rear center C. The bolt detent portion 6 has two width portions 6A, 6A circumscribing the bolt head 8a, and a connecting wall portion 6B that connects them, and faces outward in the axial center X direction of the insertion hole 5. As a wall body having a U-shape in an open posture, it is raised from the substrate main portion 3. In other words, a pair of bolt detent portions 6 arranged in the insertion holes 5 and 5 are therefore provided integrally formed on the rigid substrate 1 in a state that turn away from one another.

クッション２は、硬質基板１の片面に盛り状態で一体的に装着されており、前後一対の頂部２ａ，２ａと、それらの前後間の凹曲面２ｂと、一対の切欠き部２ｃ，２ｃとを有しており、図２（ａ）に示すように前後対称な形状に形成されている。切欠き部２ｃは、左右一対の直線壁部９，９と、それら両者を繋ぐ半円部壁部１０とを有しており、挿通孔５に相当する箇所が外周側、詳しくは、挿通孔５の軸心Ｘ方向視における硬質基板１の外周側、〔又は、一対の挿通孔５，５を結ぶ方向（軸心Ｐ方向）での外側〕から湾入して抉り取られる形状に形成されている。対向する一対の二面幅部６Ａ，６Ａは、挿通孔５に挿入されたボルト８の六角状ボルト頭８ａに密外嵌するように寸法設定されている。   The cushion 2 is integrally mounted on one side of the hard substrate 1 in a raised state, and includes a pair of front and rear apexes 2a and 2a, a concave curved surface 2b between the front and rear, and a pair of notches 2c and 2c. And has a symmetrical shape as shown in FIG. The notch portion 2c has a pair of left and right straight wall portions 9 and 9 and a semicircular wall portion 10 that connects both of them, and a portion corresponding to the insertion hole 5 is on the outer peripheral side, specifically, an insertion hole. 5 is formed in a shape that can be inserted and scraped off from the outer peripheral side of the hard substrate 1 when viewed in the X-axis direction (or the outer side in the direction connecting the pair of insertion holes 5 and 5 (axial center P direction)). ing. A pair of opposing two-sided width portions 6A, 6A are dimensioned so as to fit tightly to the hexagonal bolt head 8a of the bolt 8 inserted into the insertion hole 5.

図１等に示すように、切欠き部２ｃは、その半円部壁部１０が各二面幅部６Ａの上面（符記省略）と連結壁部６Ｂの上面（符記省略）とに亘って位置し、かつ、各直線壁部９，９の内側（半円部壁部１０側）端部が各二面幅部６Ａの上面に位置する状態で、基板主部３の前後端部とボルト回り止め部６とに跨って形成されている。これら基板主部３の前後端部及びボルト回り止め部６の上面の部分、即ち、硬質基板１における切欠き部２ｃが形成される部分は金属（硬質基板１）を剥き出し状態にすることできるが、図１に前後中心Ｃの左側にハッチングを付して示すように、薄膜状にゴム（クッション２のゴム）を設けても良い。防錆上や見かけ上で好ましい。   As shown in FIG. 1 and the like, the notch portion 2c has a semicircular wall portion 10 extending over the upper surface (not shown) of each two-sided width portion 6A and the upper surface (not shown) of the connecting wall portion 6B. And the front and rear end portions of the substrate main portion 3 in a state where the end portions of the straight wall portions 9, 9 are located on the upper surface of the two-surface width portion 6A. It is formed across the bolt detent portion 6. These front and rear end portions of the substrate main portion 3 and the upper surface portion of the bolt anti-rotation portion 6, that is, the portion where the notch 2 c is formed in the hard substrate 1 can be made to expose the metal (hard substrate 1). 1, rubber (rubber of the cushion 2) may be provided in a thin film shape as shown by hatching on the left side of the front-rear center C. It is preferable in terms of rust prevention and appearance.

この鉄道車両用ストッパＡの使用例を図４に示し、各挿通孔５，５に通される一対のボルト８，８及びナット７，７を用いて車体側の支持部材（第１部材の一例）１１のフランジ部１２に締付固定されている。この車体（鉄道車両）側への取付状態では、台車（図示省略）側の第２部材である中心ピン（第２部材の一例）１３の外周面１３Ａと適宜の間隙ｄを有してクッション２が対峙する状態に設定されている。また、組付状態では、鉄道車両用ストッパＡの前後中心Ｃの延長線上に中心ピン１３の軸心Ｙが位置するように設定されており、凹曲面２ｂの曲がりの向きと中心ピン１３の外周面１３Ａの曲がりの向きとが合致されている。尚、図示は省略されているが、鉄道車両用ストッパＡのもう一つが中心ピン１３の軸心Ｙに関して点対称となる位置に設けられている。   An example of use of the railcar stopper A is shown in FIG. 4 and a pair of bolts 8 and 8 and nuts 7 and 7 that are passed through the insertion holes 5 and 5 are used to support a vehicle body side support member (an example of a first member). ) It is fastened and fixed to the flange portion 12 of 11. In the mounting state on the vehicle body (railway vehicle) side, the cushion 2 has an appropriate gap d with the outer peripheral surface 13A of the center pin (an example of the second member) 13 which is the second member on the cart (not shown) side. Is set to face each other. In the assembled state, the axis Y of the center pin 13 is set on the extension line of the front-rear center C of the railcar stopper A, and the bending direction of the concave curved surface 2b and the outer periphery of the center pin 13 are set. The direction of bending of the surface 13A is matched. Although not shown, another railcar stopper A is provided at a position that is point-symmetric with respect to the axis Y of the center pin 13.

つまり、鉄道車両の台車に対する過剰な横揺れを規制すべく、台車側の中心ピン１３との間に横方向の間隙ｄを有する状態で鉄道車両側の支持部材１１に支持される鉄道車両用ストッパＡであり、支持部材１１にボルト止めするための一対の挿通孔５，５、を有する硬質基板１と、この硬質基板１の片面に盛り状態で一体的に装着されるとともに挿通孔５，５に相当する箇所が外周側から湾入して抉り取られる形状を有するクッション（弾性材）２とを備えて構成され、ボルト頭８ａに外接する二面幅部６Ａ，６Ａ及びそれら二面幅部どうしを繋ぐ連結壁部６Ｂを有して、挿通孔５の軸心Ｘ方向視で外側に向けて開放される姿勢のコ字状を呈するボルト回り止め部６が硬質基板１に一体的に設けられている。   That is, the railcar stopper supported by the railcar-side support member 11 with a lateral gap d between the railcar and the central pin 13 to restrict excessive rolling of the railcar relative to the cart. A hard substrate 1 having a pair of insertion holes 5, 5 for bolting to the support member 11, and being mounted integrally on one side of the hard substrate 1 in a raised state and the insertion holes 5, 5. The two-surface width portions 6A and 6A circumscribed by the bolt head 8a, and the two-surface width portions, are configured to include a cushion (elastic material) 2 having a shape in which a portion corresponding to is inserted from the outer peripheral side and scraped off. The hard substrate 1 is integrally provided with a bolt detent 6 having a connecting wall portion 6B that connects the two, and having a U-shape that is open toward the outside as viewed in the axial center X direction of the insertion hole 5. It has been.

さて、本発明による鉄道車両用ストッパＡが開発されるまでには、幾つかの試作品があった。まず、図５（ａ）に示すように、ボルト回り止め部６が、左右一対で比較的前後長さが長い直線***壁６ｈ、６ｈを硬質基板１に一体形成して成るもの（比較例１）である。即ち、挿通孔５に通されたボルト８のボルト頭８ａが対向配備される直線***壁６ｈ、６ｈに密内嵌することにより、ボルト頭８ａが回り止めされる構造である。
There were several prototypes before the development of the railcar stopper A according to the present invention. First, as shown in FIG. 5A, the bolt detent portion 6 is formed by integrally forming straight raised walls 6h, 6h, which are a pair of left and right, and have a relatively long longitudinal length, on the hard substrate 1 (Comparative Example 1). ). That is, the bolt head 8a is prevented from rotating by tightly fitting the bolt head 8a of the bolt 8 passed through the insertion hole 5 into the straight raised walls 6h, 6h arranged opposite to each other.

この比較例１による鉄道車両用ストッパＡでは、ナット締操作する際にボルト８の回り止めを行う必要がなく、便利である。しかしながら、クッション２が中心ピン１３に当接する等のストッパ作用時に、クッション２が変形して、より具体的には切欠き部２ｃの半円部壁部１０が変形してボルト頭８ａに干渉する可能性がある。当接すると亀裂発生の原因になったり、騒音が出たりするという不都合に発展し易いので改善の余地があった。   The railcar stopper A according to the comparative example 1 is convenient because it is not necessary to stop the bolt 8 when the nut is tightened. However, the cushion 2 is deformed when the stopper 2 is in contact with the center pin 13 or the like, and more specifically, the semicircular wall portion 10 of the notch 2c is deformed to interfere with the bolt head 8a. there is a possibility. There is room for improvement because it tends to develop into a disadvantage that it causes cracking or noise when contacted.

次に、図５（ｂ）に示すように、ボルト回り止め部６が、前後方向で挿通孔５の内側となる箇所に左右に長い横***壁６ｙを設けて成るもの（比較例２）が試された。即ち、六角状ボルト頭８ａの一つの面８ｍのみが横***壁６ｙに面当接することで回り止め機能を出す手段である。これだと、クッション２が変形しても、その変形が横***壁６ｙの存在によって規制されるので、ボルト頭８ａには干渉せず、比較例１の欠点は解消される。   Next, as shown in FIG.5 (b), the bolt detent | locking part 6 provides the side wall 6y long in right and left in the location which becomes the inner side of the insertion hole 5 in the front-back direction (comparative example 2). It was tried. That is, it is a means for providing a detent function when only one surface 8m of the hexagonal bolt head 8a is in surface contact with the laterally raised wall 6y. In this case, even if the cushion 2 is deformed, the deformation is restricted by the presence of the laterally raised wall 6y, so that it does not interfere with the bolt head 8a, and the disadvantage of the comparative example 1 is eliminated.

しかしながら、一つの面で回り止めさせるには、極めて高い寸法精度、つまりは、横***壁６ｙと挿通孔５との相対位置、及び挿通孔５の径それぞれの寸法精度には高いレベルが要求され、コスト高になるデメリットがあった。また、それでいて構造上、確実に回り止め機能が発揮されない可能性が残るという不安定な面があり、さらなる改善の余地が残されているものであった。   However, in order to prevent rotation on one surface, a very high level of dimensional accuracy is required, that is, the relative position between the laterally raised wall 6y and the insertion hole 5 and the dimensional accuracy of each diameter of the insertion hole 5 are required to have a high level. There was a demerit that increased the cost. In addition, there is still an unstable aspect that there is a possibility that the anti-rotation function cannot be surely exhibited in the structure, and there is still room for further improvement.

それら比較例１，２のものに対して、本発明による鉄道車両用ストッパＡによれば、ボルト頭８ａに外接する（外接可能な）二面幅部６Ａ，６Ａでもってボルト頭８ａを確実に回り止めすることができる。そして、連結壁部６Ｂの存在により、中心ピン１３と衝突して圧縮される等によって半円部壁部１０（クッション２）が挿通孔５方向に張出し変形しようとすることが生じても、その変形が牽制阻止され、ボルト頭８ａに干渉することが未然に防止されるようになる。加えて、挿通孔５の軸心Ｘ方向視でコ字状を呈するボルト回り止め部６は硬質基板１に一体形成されており、コスト安にボルト８の回り止め手段を設けることができている。   In contrast to those of Comparative Examples 1 and 2, according to the railcar stopper A according to the present invention, the bolt head 8a can be reliably secured by the two-surface width portions 6A and 6A circumscribing (possible to circumscribe) the bolt head 8a. Can prevent rotation. Even if the semi-circular wall portion 10 (cushion 2) tends to protrude and deform in the direction of the insertion hole 5 due to the presence of the connecting wall portion 6B and colliding with the center pin 13 and being compressed, The deformation is restrained and interference with the bolt head 8a is prevented in advance. In addition, a bolt detent 6 having a U-shape when viewed in the direction of the axis X of the insertion hole 5 is formed integrally with the hard substrate 1, and a detent means for the bolt 8 can be provided at low cost. .

〔実施例２〕
図３に、実施例２による鉄道車両用ストッパＡの要部を示してある。これは、挿通孔５に通されたボルト８のボルト頭８ａに作用してボルト８の挿通孔５からの抜け出しを防止（又は規制）する脱落防止手段Ｂが装備された鉄道車両用ストッパＡである。脱落防止手段Ｂは、図３（ａ），（ｂ）に示すように、一対の二面幅部６Ａ，６Ａの上面１４から内側面１５に架けてクッション２のゴムを延長して形成される一対の張出し弾性筋１６，１６を設けて構成されている。尚、張出し弾性筋１６の幅を変えたり、或いは、１箇所にのみ張出し弾性筋１６を設ける構造も可能である。 [Example 2]
FIG. 3 shows a main part of the railcar stopper A according to the second embodiment. This is a railcar stopper A equipped with a drop-off prevention means B that acts on the bolt head 8a of the bolt 8 passed through the insertion hole 5 to prevent (or regulate) the bolt 8 from coming out of the insertion hole 5. is there. As shown in FIGS. 3A and 3B, the drop-off prevention means B is formed by extending the rubber of the cushion 2 from the upper surface 14 of the pair of two-surface width portions 6A and 6A to the inner surface 15. A pair of overhanging elastic muscles 16 and 16 are provided. In addition, the structure which changes the width | variety of the overhang | stretching elastic muscle 16 or provides the overhanging elastic muscle 16 only in one place is also possible.

一対の張出し弾性筋１６，１６の間隔Ｗは、ボルト頭８ａの互いに平行な二面幅部６Ａ，６Ａの間隔Ｌよりも僅かに小さく（Ｗ＜Ｌ）なるように設定されている。ボルト８を挿通孔５に挿入する際は一対の張出し弾性筋１６，１６を弾性変形（圧縮変形）させてボルト頭８ａを無理通しして入れ込む。挿入孔５に挿通されたボルト８は、図３（ｂ）に示すように、張出し弾性筋１６の下面１６ａがボルト頭８ａの直上に位置して邪魔をする状態になっている。
The distance W between the pair of overhanging elastic muscles 16 and 16 is set to be slightly smaller (W <L) than the distance L between the two parallel width portions 6A and 6A of the bolt head 8a. When the bolt 8 is inserted into the insertion hole 5, the pair of overhanging elastic muscles 16 and 16 are elastically deformed (compressed) and the bolt head 8a is forcedly inserted. As shown in FIG. 3 (b), the bolt 8 inserted through the insertion hole 5 is in a state in which the lower surface 16a of the overhanging elastic muscle 16 is located immediately above the bolt head 8a and obstructs.

故に、自重等によってボルト８が挿通孔５から抜け出そうとすると、ボルト頭８ａが張出し弾性筋１６の下面１６ａに当接することとなり、張出し弾性筋１６がゴム等の弾性材であってもボルト８が抜け出そうとする力位には十分対抗することができる。従って、ストッパＡの組付作業時において、ストッパＡを横向きや下向きに操作することがあってもボルト８が抜け落ちてしまわず、組付性が向上するようになる。その結果、弾性材を二面幅部６Ａに設ける程度の廉価な手段により、ボルト８の挿通孔５からの抜け出しが牽制阻止されて組付性が向上する合理的な鉄道車両用ストッパＡとなる利点がある。 Therefore, if the bolt 8 tries to come out of the insertion hole 5 due to its own weight or the like, the bolt head 8a comes into contact with the lower surface 16a of the overhanging elastic muscle 16, and the bolt 8 even if the overhanging elastic muscle 16 is an elastic material such as rubber. Can counter the power that tries to escape. Therefore, when the stopper A is assembled, the bolt 8 does not come off even if the stopper A is operated sideways or downward, and the assemblability is improved. As a result, a reasonable railcar stopper A in which assemblability is improved by preventing the bolt 8 from coming out of the insertion hole 5 by inexpensive means such as providing an elastic material on the two-surface width portion 6A. There are advantages.

Moreover, the insertion hole 5 and the bolt detent | locking part 6 may be the stopper A for rail vehicles which takes the structure provided only in one place, or the structure provided in three or more places.
