〔発明の利用分野〕
本発明は鉄道車両用ボルスタレス台車に関するもので、
特に車体の高さ調整に適するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a bolsterless bogie for a railway vehicle,
It is particularly suitable for adjusting the height of the vehicle body.
従来技術による実施例を第１図、第２図に示す。 Examples according to the prior art are shown in FIGS. 1 and 2.
ボルスタレス台車の場合、車体１は空気ばね４を介して
直接台車枠６の上に乗っている。台車枠６は軸ばね７を
介して輪軸８の士に乗っている。In the case of a bolsterless bogie, the car body 1 rests directly on a bogie frame 6 via an air spring 4. The bogie frame 6 rests on the wheel axle 8 via an axle spring 7.
通常の使用においては、】〜２年毎に車輪の踏面を削正
するため車輪直径は次第に小さくなり車体１の高さが低
くなって鳴る。これを調整するため、車体１と空気ばね
４の上面板３の間にライナー２を入れて高さ調整を行な
うのが普通であった。In normal use, the wheel treads are ground every two years, so the diameter of the wheels gradually decreases, causing the height of the vehicle body 1 to become lower. In order to adjust this, it has been common practice to insert a liner 2 between the vehicle body 1 and the top plate 3 of the air spring 4 to adjust the height.
第２図にその調整要領を示す。車体１と台車枠６の間に
くら９を入れた後空気ばね４の中の空気を抜くと、空気
ばね４が縮みくら９が車体１の荷重を台車枠６に伝える
。空気ばね４を頁に縮めると上面板３と車体１の間に隙
間が生じるので、これを利用してライナー２の量を加減
することは極めて容易である。ライナー１１１１整後は
、空気ばね４に空気を入れれば空気ばね４は伸び車体１
の荷重を負担するため、（ら９を取外すことができる。Figure 2 shows the adjustment procedure. When the air in the air spring 4 is released after the saddle 9 is inserted between the car body 1 and the bogie frame 6, the air spring 4 contracts and the bow 9 transmits the load of the car body 1 to the bogie frame 6. When the air spring 4 is compressed, a gap is created between the top plate 3 and the vehicle body 1, so it is extremely easy to use this gap to adjust the amount of liner 2. After aligning the liner 1111, if you put air into the air spring 4, the air spring 4 will stretch and the car body 1 will be expanded.
(9) can be removed to bear the load.
このような従来技術による場合、空気ばね４の上面板３
の直径りは通常６００〜７００閣もありライナー２が極
めて大形となり、重量も大で取扱いが不便であるという
問題点があった。In the case of such conventional technology, the top plate 3 of the air spring 4
The diameter of the liner is usually 600 to 700 mm, making the liner 2 extremely large and heavy, making it inconvenient to handle.
空気ばオλ４の下面板５と台車枠６０間にライナーを入
れれば、下面板５はその曲゛径ｄが３００鴫程度のため
ライナーは小形軽量化できる。しかし。If a liner is inserted between the lower plate 5 of the air filter λ4 and the bogie frame 60, the liner can be made smaller and lighter because the lower plate 5 has a curved diameter d of about 300 mm. but.
この方式を採用すると、ライナー調整に際し車体１、空
気ばね４を外さないと下面板５と台車枠６の間にライナ
ーを入れることができず、調整作業が面倒になるという
問題があった。When this method is adopted, there is a problem that the liner cannot be inserted between the bottom plate 5 and the bogie frame 6 unless the car body 1 and the air spring 4 are removed when adjusting the liner, making the adjustment work troublesome.
本発明の目的は、／Ｊ）形のライナーを用いる作業容易
なライナー調整のできるボルスタレス台車を提俳するこ
とにある。An object of the present invention is to provide a bolsterless truck that uses a /J)-shaped liner and allows for easy liner adjustment.
本発明の要点は、空気ばね下面板と台車枠の間に空気ば
ね単体を持Ｊげるに十分な使方を有する機構を配置し、
ライナー調整時空気ばねな持ち上げ、ライナーが小形と
なる下面板と台車枠の間でライナー調整ｌ整を可能とし
たことにある。The key point of the present invention is to arrange a mechanism that can be used sufficiently to hold a single air spring between the air spring bottom plate and the bogie frame,
When adjusting the liner, the air spring lifts it up, making it possible to adjust the liner between the bottom plate and the bogie frame, which makes the liner smaller.
以下、本発明の実施例１を第３図ないし牢７図に示す。 Embodiment 1 of the present invention is shown in FIGS. 3 to 7 below.
第３図はライナー調整時の要領を示し、第４図は本発明
の一実施例を示す空気ばね部の詳細図である。FIG. 3 shows the procedure for adjusting the liner, and FIG. 4 is a detailed view of the air spring section showing one embodiment of the present invention.

が伸びた時の空気シールのために設けである。First, in the standing state, when the saddle 9 is placed between the car body 1 and the bogie frame 6 and the air in the air spring 2 is let out, the air spring 2 is compressed and the spring 8, which had been compressed until then, is expanded. Since the spring 18 has sufficient spring force and stroke to lift the air spring 12, the upper part of the air spring 12 from the bottom plate 13 is lifted upward by the force of the spring 18, and remains in close contact with the vehicle body 1. , and a gap is created between the bogie frame 6 and the bottom plate 3. Even in this state, the stopper fixing fitting 19 is positioned on the truck frame 6 by the dowel 15, and the spring 1
It is pressed against the bogie frame 6 by a reaction force of 8. Therefore, the position of the air spring 12 does not move from side to side (Liner J
4 can be adjusted. 0 ring 20 is a spring]8
This is provided to provide an air seal when it is extended.
第５図は未発明の他の実施例を示す要部詳細図である。FIG. 5 is a detailed view of main parts showing another embodiment which has not yet been invented.
先の実施例では、下面［１３と位置決め金具］９の間の
ばね１８の伸縮にともなう相対動きに対し空気シールを
するため０リング２０を用いていたが、この実施例では
、上下に伸縮可能で気密を保てるベローズｎを用い摺動
部分をな（している。In the previous embodiment, the O-ring 20 was used to provide an air seal against the relative movement caused by the expansion and contraction of the spring 18 between the lower surface [13 and the positioning metal fitting] 9, but in this embodiment, the O-ring 20 can be expanded and contracted up and down. The sliding parts are made of bellows that can maintain airtightness.
本実施例においても、下面板１３でライナー調整をする
要領などは先の実施例と全（同一である。In this embodiment as well, the procedure for adjusting the liner using the lower plate 13 is completely the same as in the previous embodiment.
第６図は本発明のさらに他の実施例を示す空気ばね部の
詳細図である。FIG. 6 is a detailed view of an air spring section showing still another embodiment of the present invention.
まず在姿状態で、くら９を車体１と台車枠６の間に配置
し空気ばね１２の空気を抜曵と、空気ばね］２は縮み土
面板】１は車体１から離れ下っで４る。First, in the standing state, the saddle 9 is placed between the car body 1 and the bogie frame 6, and when the air in the air spring 12 is extracted, the air spring [2] contracts, and the earth plate [1] separates from the car body 1 and moves downward.

整することができる。Next, when a tool is applied to the claws 23 provided on the outer periphery of the lower plate 13 and rotated, the positioning metal fittings 19. Anti-vibration rubber 24. Since the screw plate 25 is positioned on the truck frame by the detent 27 and does not rotate, the portion of the air spring 12 above the bottom plate 13 rises upward due to the action of the screws 26 provided on the bottom plate 13 and the screw plate 25. . Therefore, since a gap is created between the lower surface Ji13 and the truck frame, the liner]4 can be easily adjusted.
ライナー調整後は、下面板１３を先に逆方向に回せば下

ある。０リング２σは、下面板１３が上下に動く際のシ
ールのために取付けである。After adjusting the liner, if the lower plate 13 is first turned in the opposite direction, it will descend downward, and the lower plate 13 will come into close contact with the bogie frame 6 via the adjusted liner 14. The vibration isolating rubber 24 is provided to provide relief so that excessive force is not applied to the screw 26 when the adhesion between the bottom plate 13 and the liner 4 is poor. The O-ring 2σ is attached for sealing when the bottom plate 13 moves up and down.
第７図は第６図の変形例を示し、空気ばね１２への吸排
気がすべて上方よりなされる場合を示す。FIG. 7 shows a modification of FIG. 6, in which all air intake and exhaust to and from the air spring 12 is performed from above.
この場合、（Ｏｌａｒ決め金具１９と下面＆１３の間が
空気室になっていないため、０リングが省かれる。In this case, the O-ring is omitted because there is no air chamber between the Olar fitting 19 and the lower surface &13.
なお、従来はライナー調整が不可能であった空気ばね上
面板が車体にめり込Ａ、でいるような構造の台車におい

回旋である。In addition, even in a bogie having a structure in which the air spring top plate is recessed into the car body, which was conventionally impossible to adjust the liner, according to the present invention, the liner can be adjusted without changing the rotation.
本発明によれば、ライナーが小形化できライナー調整作
業が容易になり、それにより軽量化ができるという効果
がある。According to the present invention, the liner can be made smaller, the liner adjustment work becomes easier, and the weight can thereby be reduced.
