本発明は、鉄道車両用台車等に用いられるロールゴムば
ねに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a roll rubber spring used in a bogie for a railway vehicle or the like.
従来公知のロールゴムばねな第４図および第５図に示す
。円錐状心金９は、軸箱体２にボルト４で固定される。A conventionally known roll rubber spring is shown in FIGS. 4 and 5. The conical mandrel 9 is fixed to the axle box body 2 with bolts 4.
１０はばね座である。また、つりがね状外筒７は、ボル
ト乙によって１台車枠５に設けられている取付座６に固

在させられており、ころがり変形により軸箱２に加わる
上下荷重を台車枠５に伝えると共に、軸箱２の台車枠５
への位置決めも合わせて行なっている。10 is a spring seat. Further, the hanging bell-shaped outer cylinder 7 is fixed to a mounting seat 6 provided on the bogie frame 5 by bolts O. The annular rubber ring 8 is interposed between the core metal 9 and the outer cylinder 7, and transmits the vertical load applied to the axle box 2 due to rolling deformation to the bogie frame 5, and also transmits the vertical load applied to the axle box 2 to the bogie frame 5 of the axle box 2.
The positioning is also carried out at the same time.
第４図、第５図に示したロールゴムばねの坦合。Fitting of the roll rubber spring shown in FIGS. 4 and 5.
外筒７の上部は中空になってお１１．ゴム環８の内径よ
りも相当大きな穴がおいている。この穴は。11. The upper part of the outer cylinder 7 is hollow. There is a hole considerably larger than the inner diameter of the rubber ring 8. This hole is.
第６図に示すように、ゴム環８を定期点検するためある
いは交換するために、治具１１を挿入して下方へ押出す
ため曇−必要なものである。したがって。As shown in FIG. 6, in order to periodically inspect or replace the rubber ring 8, a jig 11 is inserted and pushed downward. therefore.
この穴の径Ｄ２は小さくすることができない。この結果
、外筒７を取付座６に位置決めするための印ろう穴の径
Ｄ１も大きくならざるを得ない。通常の電車用台車にお
いては、径Ｄ１は１００〜２００朋であり、台車枠側の
加工はリーマ−等によっては困難である。通常、この加
工はポーリング加工によって行なっており１台車枠の加
工に多大の時間を要している。The diameter D2 of this hole cannot be made small. As a result, the diameter D1 of the dowel hole for positioning the outer cylinder 7 on the mounting seat 6 must also become large. In a typical train bogie, the diameter D1 is 100 to 200 mm, and machining of the bogie frame side is difficult using a reamer or the like. Normally, this processing is performed by polling, and it takes a lot of time to process one bogie frame.
この対策として、例えば第７図に示す如く、アダプター
１３を用いることが考えられる。しかし。As a countermeasure against this problem, it is conceivable to use an adapter 13 as shown in FIG. 7, for example. but.
この場合にはアダプタ１３が必要となって部品数が増え
るし、加工面も増大するので加工時間の短縮にはならな
い。In this case, the adapter 13 is required, which increases the number of parts and increases the surface to be machined, so the machining time cannot be shortened.
本発明の目的は、構造が簡単で加工が容易なロールゴム
ばねな提供することである。An object of the present invention is to provide a roll rubber spring that is simple in structure and easy to process.
本発明は、ロールゴムの外周上端を平板でふさぎ、位置
決めのための小径の突起を設けると共に。The present invention covers the upper end of the outer periphery of the roll rubber with a flat plate and provides a small diameter protrusion for positioning.
該外筒上端なふさく゛平板にゴム環取外し用の複数の穴
または空間を設けたことを特徴とする。これによって、
簡単な構造で台車枠の機械加工も容易となる。A feature is that a plurality of holes or spaces for removing the rubber ring are provided in the flat plate at the upper end of the outer cylinder. by this,
The simple structure also facilitates machining of the bogie frame.
以下、本発明を具体的な実施例に基づき詳細に説明する
。Hereinafter, the present invention will be explained in detail based on specific examples.
本発明の実施例の断面図を第１図に平面図を第２図に示

を平板でふさがれており、その中央に直径Ｄ５の小形の
円柱状突起を設けている。この円柱状突起が取付座１７
に設けた穴にはまＦ）込んで外筒１８の台車枠５に対す
る位置決めを行なっている。突起の径Ｄ５は３０〜６０
簡であり台車枠側の加工はドリル、リーマ−などで容易
に精度良鳴加工できる。A cross-sectional view of an embodiment of the present invention is shown in FIG. 1, and a plan view is shown in FIG. 2. The outer cylinder 18 has its upper end surface in contact with the bogie frame mounting seat 17 covered with a flat plate, and a small cylindrical projection with a diameter D5 is provided in the center thereof. This cylindrical projection is the mounting seat 17.
The outer cylinder 18 is positioned with respect to the bogie frame 5 by inserting it into the hole provided in F). The diameter D5 of the protrusion is 30 to 60
It is simple and the bogie frame side can be easily machined with good accuracy using a drill, reamer, etc.
また、外筒上部なふさく板には穴２３が円周上に数個開
けてあり、ゴム環１９を外周１８より外す際はゴム環１
９と外筒１８を台車枠より取外した状態で。In addition, several holes 23 are made on the circumference in the closing plate at the top of the outer cylinder, and when removing the rubber ring 19 from the outer periphery 18, the rubber ring 19
9 and outer cylinder 18 are removed from the truck frame.
治具２１によりゴム環１９を押し出せば良い。The rubber ring 19 may be pushed out using the jig 21.
第３図は本発明の他の実施例を示し穴２３の代りに円以
外の不規則な形状の六がを設けた場合を示す。その効果
１作用などは第１の実施例と同様である。FIG. 3 shows another embodiment of the present invention, in which the hole 23 is replaced by a hole having an irregular shape other than a circle. Effect 1 and other effects are similar to those of the first embodiment.
本発明の実°施例によれば、下部の効果がある。According to an embodiment of the present invention, there is a lower effect.
１、 余分な部分の増加なしに台車枠のポーリング加工
を廃止し、加工容易なリーマ加工に代替でき、加エコヌ
トが下る。1. The polling process of the bogie frame can be abolished without increasing unnecessary parts, and it can be replaced with the easy-to-process reaming process, reducing the cost of machining.
２、台車枠下部に大径の穴を設ける必要がなくなるため
台車枠の設計の自由度が増し最適設計が容易となる。2. Since there is no need to provide a large-diameter hole in the lower part of the bogie frame, the degree of freedom in designing the bogie frame increases and optimal design becomes easier.
３、 ポーリング加工がなくなるため加工の段取変更が
少なくなり１時間短縮ができる。3. Since polling is no longer required, there are fewer changes in machining setups, which saves one hour.
以上詳細に説明したように本発明によれば、構造が簡単
で加工が容易なロールゴムばねな提供できる。As described in detail above, according to the present invention, it is possible to provide a roll rubber spring that has a simple structure and is easy to process.
