従来は、例えば図4に示すように、軸箱aと台車枠bとの間に、下から調整板 c、防振ゴムd、軸ばね座下e、コイルばねfを介在させ、前記軸箱aから前記 台車枠bの前後方向に沿つて、ほぼ水平に突設した張り出し部g,kに、それぞ れ積層ゴムi,jを装着し、これら積層ゴムi,jの中心穴k,lに、前記台車 枠bの下面に取り付けた内筒m,nを挿入して固着する構造が提供されている。 Conventionally, as shown in FIG. 4, for example, an adjustment plate was installed from below between the axle box a and the bogie frame b. c, vibration isolating rubber d, shaft spring seat e, and coil spring f, from the shaft box a to the Along the front and back direction of the bogie frame b, there are projecting parts g and k that protrude almost horizontally. The rubber laminations i and j are attached to the center holes k and l of the rubber laminations i and j. A structure is provided in which inner cylinders m and n attached to the lower surface of frame b are inserted and fixed.
【0003】 上記構成においては、軸箱aの上方にコイルばねfが入り込むために、この部 位の断面ねじり剛性が低下し、輪軸に働く左右荷重Q(図5参照)が、内筒m, nの左右方向に作用し、特に台車枠bの外寄りの内筒mに作用した左右荷重Qは 、コイルばねfが入り込んだ部位の台車枠bの断面に、過大なねじり応力P(図 6参照)を発生させ、このねじり応力Pは左右荷重Qと、左右荷重Qの作用点O 1 から台車枠bの断面のせん断中心O2までの距離lの積、すなわちQ・lに比例 する。0003 In the above configuration, since the coil spring f enters above the axle box a, this part The cross-sectional torsional rigidity of the inner cylinder m, The left and right load Q acting in the left and right direction of n, and especially acting on the inner cylinder m on the outside of the bogie frame b, is , an excessive torsional stress P (Fig. 6), and this torsional stress P is applied to the left and right load Q and the point of action O of the left and right load Q. 1 from the shear center O of the cross section of the bogie frame b2The product of the distance l, that is, proportional to Q・l do.

この考案の上述の装置において、各種車両重量の違いによるばね高さの調整を 、軸箱直上の調整板と、内筒と台車枠との間の高さ調整板との厚さを同量だけ増 減することにより行ない、またばね高さの調整は、車両在姿状態(車体を架装し た本来の姿)で、台車枠の上部から防振ゴムのねじ部にボルトをねじ込むことに より、防振ゴムと軸箱との間に調整板を挿入して行なうものである。 In the above-mentioned device of this invention, the spring height can be adjusted according to the difference in the weight of various vehicles. , increase the thickness of the adjustment plate directly above the axle box and the height adjustment plate between the inner cylinder and the bogie frame by the same amount. The spring height is adjusted by adjusting the height of the vehicle as it is (with the vehicle body mounted). The bolt was screwed into the threaded part of the anti-vibration rubber from the top of the bogie frame. Therefore, an adjustment plate is inserted between the vibration isolating rubber and the axle box.

次にこの考案を図1ないし図3に示す実施例によつて、詳細に説明する。 先ず図1及び図2において、1は軸箱であつて、この軸箱1と門形断面の台車 枠2との間に、下から調整板3、防振ゴム4、軸ばね座下5、金属性のコイルば ね6を介在させる。 Next, this invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 3. First, in FIGS. 1 and 2, 1 is an axle box, and this axle box 1 and a trolley with a gate-shaped cross section Between the frame 2 and the 6 is interposed.
【0008】 前記軸箱1の車両の進行方向前後に、外寄りが高く構成されている前記台車枠 2の形状に合わせて、台車枠2の外寄りを高く、台車枠2の内寄りを低くした張 出し部7,8を、台車枠2に沿つて形成する。[0008] The bogie frame is configured such that the axle box 1 has a high outer side at the front and rear in the vehicle traveling direction. 2, the outer side of the bogie frame 2 is made higher and the inner side of the bogie frame 2 is lowered. Projecting parts 7 and 8 are formed along the bogie frame 2.
【0009】 前記張り出し部7,8に、車両の進行方向と車両の左右方向でばね常数の異な る積層ゴム9,10を挿入し、更に安全のため、押え金11,12を挿入して、 これら積層ゴム9,10の脱出防止を図つている。[0009] The overhangs 7 and 8 are provided with spring constants that are different in the traveling direction of the vehicle and in the left and right directions of the vehicle. Insert the laminated rubber 9 and 10, and for safety, insert the presser feet 11 and 12. Efforts are made to prevent these laminated rubbers 9 and 10 from escaping.
【0010】 一方、前記台車枠2の下部には前記積層ゴム9,10の直上において、高さ調 整板13,14を介して、内筒15,16がボルト17,18で固定され、この 際これら内筒15,16は、前記台車枠2に穿設された加工穴19,20に精度 よく嵌め合わされており、台車の固定軸距、軸受左右間隔、軸受対角寸法を正確 に保つている。0010 On the other hand, at the bottom of the bogie frame 2, there is a height adjustment section directly above the laminated rubber 9, 10. Inner cylinders 15 and 16 are fixed with bolts 17 and 18 via straightening plates 13 and 14, and this At the same time, these inner cylinders 15 and 16 are fitted with precision holes 19 and 20 drilled in the bogie frame 2. They fit together well, and the fixed wheelbase of the bogie, the bearing left and right spacing, and the bearing diagonal dimensions are accurate. I'm keeping it.
【0011】 前記内筒15,16は、前記積層ゴム9,10の中心穴21,22に挿入され 、それぞれ間座23,24と吊り金具25,26とを介してナツト27,28で 固定される。[0011] The inner cylinders 15, 16 are inserted into the center holes 21, 22 of the laminated rubber 9, 10. , with nuts 27 and 28 via spacers 23 and 24 and hanging fittings 25 and 26, respectively. Fixed.
【0012】 各種車両重量の違いによるばね高さの調整は、調整板3と高さ調整板13,1 4の厚さを同量だけ増減することによつて行なう。0012 Adjustment of the spring height due to differences in vehicle weight is possible using the adjustment plate 3 and height adjustment plates 13 and 1. This is done by increasing or decreasing the thickness of 4 by the same amount.
【0013】 上記構成において、台車枠2の外寄りの積層ゴム9を、可及的に高い位置に配 置することにより、台車枠2の外寄りの内筒15に働く、左右荷重Qの作用中心 位置を車軸中心よりH(図3参照)だけ高くして、断面B−Bに働くねじりモ− メントを少なく抑えることができる。[0013] In the above configuration, the laminated rubber 9 on the outside of the bogie frame 2 is placed as high as possible. By placing the The position is raised by H (see Figure 3) from the axle center, and the torsion motor acting on the cross section ment can be kept to a minimum.
【0014】 台車枠2の内寄りの積層ゴム10及び内筒16は、台車枠2の外寄りのそれを 高くした量と同量(H)だけ、車軸中心より低く取り付けることにより、軸受の 寿命を低下させる前後軸回りのねじりモ−メントを発生させることがない。[0014] The laminated rubber 10 and inner cylinder 16 on the inner side of the bogie frame 2 are different from those on the outer side of the bogie frame 2. By installing the bearing lower than the center of the axle by the same amount (H) as the height of the bearing, There is no generation of torsional moments around the front and rear axes that reduce service life.
【0015】 次に積層ゴムを段差配置したことにより、軸箱のピツチング方向の回転剛性を 向上させて、軸箱のピツチ運動から発生する車体の高周波振動を抑えることがで きる理由を説明する。[0015] Next, by arranging the laminated rubber in steps, the rotational rigidity in the pitching direction of the axle box is improved. It is possible to suppress the high-frequency vibrations of the car body caused by the pitch movement of the axle box. Explain why.
【0016】 今、軸箱が軸中心回りに△θだけ回転した際、軸箱を復元する回転力Tは、図 5に示すように積層ゴムを水平に配置した場合は、 T=k1・△H・2D=k1・D・△θ・2Dであり、軸箱ピツチ剛性GPHは T=GPH・△θであるから、(なおk1は積層ゴムの垂直方向の弾性力、k2は 水平方向の弾性力を示す) GPH=T/△θ=2k1D2となる。[0016] Now, when the axle box is rotated by △θ around the center of the shaft, the rotational force T that restores the axle box to its original state is, if the laminated rubber is arranged horizontally as shown in Figure 5, T = k 1 · Since △H・2D=k 1・D・△θ・2D, and the axle box pitch rigidity GPH is T=GPH・△θ, (k 1 is the elastic force in the vertical direction of the laminated rubber, and k 2 is (represents elastic force in the horizontal direction) GPH=T/Δθ=2k 1 D 2 .
【0017】 一方、積層ゴムを図3に示すように、段差配置した場合は、同様にして T=k1・l△θ・D/l・2D+k2・l・△θH/l・2H =k1・△θ・2D2+k2・△θ・2H2 =2(k1D+k2H2)△θ 軸箱ピツチ剛性GPSは T=GPS・△θ GPS=T/△θ=2(k1D2+k2H2) よつて、 GPS=GPH+2k2H2 つまり、GPSはGPHより2k2・H2だけ大となる。[0017] On the other hand, if the laminated rubber is arranged in steps as shown in Figure 3, T=k1・l△θ・D/l・2D+k2・l・△θH/l・2H =k1・△θ・2D2+k2・△θ・2H2 =2(k1D+k2H2)△θ Axle box pitch rigidity GPS T=GPS・△θ GPS=T/△θ=2(k1D2+k2H2) Then, GPS=GPH+2k2H2 In other words, GPS is 2k more than GPH.2・H2only becomes larger.
【0018】[0018]
上述の次第で、この考案の上述の構造の装置によれば、各種車両重量の違いに よるばね高さの調整を、軸箱上の調整板と、張り出し部の積層ゴムに圧入した内 筒と台車枠との間の高さ調整板との、厚さの同量の増減によつて容易に行なえる と共に、台車枠外寄りの積層ゴムを高い位置に配置することによつて、ねじりモ −メントを少なく抑えることができるという効果を奏するものである。 According to the above, the device with the above structure of this invention can be used for different vehicle weights. The height of the spring can be adjusted using the adjustment plate on the axle box and the inner part press-fitted into the laminated rubber of the overhang. This can be easily done by increasing or decreasing the thickness by the same amount using the height adjustment plate between the cylinder and the bogie frame. At the same time, by placing the laminated rubber near the outside of the bogie frame in a high position, torsion is reduced. - It has the effect of being able to suppress the amount of ment.
