る軸バネゴムの倒れの問題があった。Conventional shaft springs for railway vehicles are the conical springs introduced in "Recent Developments in Bogies for Conventional Railways", page 102 of "Vehicle Technology No. 168" published by the Japan Railway Vehicle Manufacturers Association, February 1985. Like the laminated rubber type axle box support device, the entire support device including the bogie frame can be made smaller and lighter, and maintenance is easier.However, there is a problem of the axle spring rubber falling down due to braking force or longitudinal acceleration. .
上記従来技術は、軸バネの倒れの点については配慮がな
されていなかった。In the above-mentioned conventional technology, no consideration was given to the collapse of the axial spring.
本発明の目的は、小形ｉｆ鼠で、しかも組立、保守が容
易で、かつ、輔バネゴムの倒れを防止することにある。An object of the present invention is to provide a small-sized device that is easy to assemble and maintain, and to prevent the rubber spring from falling down.
上記目的は、円錐状の金具にゴムを加硫接着した円錐積
層ゴムとコイルバイ１、または１円形ソング状のゴムに
内、外筒を組合せたロールゴムとコイルバネを併用する
ことにより達成される。The above object is achieved by using a combination of a conical laminated rubber in which rubber is vulcanized and bonded to a conical metal fitting and a coil spring, or a roll rubber and a coil spring in which a circular song-shaped rubber is combined with an inner and outer cylinder.

イルバネを併用したものは、円錐積層ゴムで水平方向の
特性が自由に可変できる特徴をもっており、しかも、コ
イルバネな外側に配置することによりふんばりを大きく
することができる。A conical laminated rubber made by vulcanizing and adhering exposed rubber with a conical metal fitting and a coil spring has the characteristic that the horizontal characteristics of the conical laminated rubber can be freely varied, and by placing it on the outside of the coil spring. You can increase your size.

ゴムとコイルバネを併用したものは、円形リング状ゴム
の交換を容易に行なうことができ、しかも、コイルバネ
を外側に配置しているため、ふんばりを大きくすること
ができる。In addition, when a coil spring is used in combination with a roll rubber built into the inner and outer cylinders of a circular ring-shaped rubber, the circular ring-shaped rubber can be easily replaced, and the coil spring is placed on the outside. Therefore, the size can be increased.
これら両者は、ゴムバネの外側にコイルバネを併用した
ことにより、軸ゴムバネがブレーキ力や前後加速度で倒
れることはない。In both of these, a coil spring is used on the outside of the rubber spring, so that the shaft rubber spring does not fall down due to braking force or longitudinal acceleration.
以下、本発明の一実施例を第１図および第２図により説
明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

ム１の外側にコイルバネ２含組込み、軸バネ座３をボル
ト４により円錐積層ゴム１に組付けている。円錐積層ゴ
ムｌはコイルバネ２との併用のため金ヤを小形化でき、
製作費を低減できる。In FIG. 1, a coil spring 2 is installed on the outside of a conical laminated rubber 1 in which rubber is vulcanized and bonded to a conical metal fitting, and an axial spring seat 3 is attached to the conical laminated rubber 1 with bolts 4. The conical laminated rubber l can be used in combination with the coil spring 2, so the metal ring can be made smaller.
Production costs can be reduced.
また、円錐積層ゴム１は水平方向の特性が可変できるた
め、最適な軸箱支持剛性値を選ぶことができる。Further, since the characteristics of the conical laminated rubber 1 in the horizontal direction can be varied, the optimum axle box support rigidity value can be selected.
第２図は円形リング状のゴム５に内筒６．外筒７を組合
せたロールゴム方式の軸バネの外側にコイルバネ８を併
用したものである。Figure 2 shows a circular ring-shaped rubber 5 and an inner cylinder 6. A coil spring 8 is used on the outside of a roll rubber type shaft spring combined with an outer cylinder 7.
これら両者ともゴムバネとコイルバネを併用し、コイル
バネにふんばりをもたせている。そのため、軸バネゴム
ユニットが、ブレーキ力や前後加速度により倒れること
はない。Both of these use a combination of rubber springs and coil springs, giving the coil springs a sense of fluff. Therefore, the shaft spring rubber unit will not fall down due to braking force or longitudinal acceleration.
本発明によれば次の効果がある。 According to the present invention, there are the following effects.
（１） ゴムの加硫金型を小形化できるので、製作費
が低減できる。(1) Since the rubber vulcanization mold can be downsized, manufacturing costs can be reduced.
（２）軸箱支持部の分解２組立が容易になる。(2) Disassembly and assembly of the axle box support section becomes easier.
（３） 小形の円維禎層ゴムおよびロールゴムのゴム
部のみ交換すれば継続使用できるので、保守費が低減で
きる。(3) Maintenance costs can be reduced because continued use can be achieved by replacing only the rubber parts of the small circular fiber layer rubber and roll rubber.
（４） コイルバネとの併用であるため、ブレーキ力
や、前後加速度による軸バネゴムの倒れを防止できる。(4) Since it is used in combination with a coil spring, it is possible to prevent the shaft spring rubber from collapsing due to braking force or longitudinal acceleration.
