Description
【0001】[0001]
本考案は鉄道車両用台車に関するものである。 The present invention relates to a bogie for railway vehicles.
【0002】[0002]
従来の鉄道車両用台車においては、それぞれ一対の車輪を保持する各輪軸は、 両端部を軸受収納の軸箱によって保持されており、台車枠は、前後方向両端部の 下側を輪軸の各軸箱との間に装着されたコイルバネや空気バネなどの弾性伸縮部 材によって、上下、左右、および前後方向に移動し得るように弾性支持されてい る。また、互いに独立をなす前後方向の一対の輪軸は、いつも平行をなすように 台車枠に取り付けられ、それぞれ別個のモーターにより回転させられている。 In conventional bogies for railway vehicles, each wheel axle that holds a pair of wheels is held at both ends by a shaft box that houses bearings, and the bogie frame is located at the lower end of each longitudinal end of each wheel axle. It is elastically supported so that it can move up and down, left and right, and front and back by elastic expansion and contraction members such as coil springs and air springs that are mounted between the box and the box. In addition, a pair of front and rear wheel axles that are independent of each other are attached to the bogie frame so that they are always parallel to each other, and are rotated by separate motors.
【0003】[0003]
しかしながら、上記の鉄道車両用台車には以下に述べる困難な点がある。 すなわち、図9に示すように、従来のように平行をなす一対の輪軸と台車枠と が弾性伸縮部材によって連結されているだけの場合には、鉄道車両aがレールb の曲線部分を通過するとき、各台車枠Fに取り付けられた一対の輪軸d,dは、 互いに独立で平行に保たれたままであるため、レールbの曲率中心Oを通る方向 に回転することはできない。 However, the above bogies for railway vehicles have the following difficulties. That is, as shown in FIG. 9, when a pair of parallel wheel axles and a bogie frame which are parallel to each other are merely connected by an elastic expansion / contraction member as in the conventional case, the railway vehicle a passes through the curved portion of the rail b. At this time, since the pair of wheel shafts d, d attached to each bogie frame F remain independent and parallel to each other, they cannot rotate in the direction passing through the curvature center O of the rail b.
【0004】 このため、一対の輪軸d,dに固定されている各車輪e,eの回転方向は、車 輪eが転動しているレールbの接線方向と一致しないで滑りを起こすから、レー ルbと車輪eの両方を磨耗させ、騒音を発生し、鉄道車両aに余分な振動を与え て乗り心地を悪くするほか、走行速度がスピードアップされるに伴い平行なレー ルbに及ぼす力を増大してレール間距離を拡大し、鉄道車両aの脱線事故を起こ しやすくする懸念があった。For this reason, the rotation directions of the wheels e, e fixed to the pair of wheel shafts d, d do not coincide with the tangential direction of the rail b on which the wheel e is rolling, and slip occurs. Both the rail b and the wheels e are worn out, noise is generated, the railcar a is given excessive vibration, which makes the ride uncomfortable, and the parallel rail b is affected as the traveling speed is increased. There was a concern that the force would be increased to increase the distance between the rails, which would easily cause a derailment accident of the railway vehicle a.
【0005】 本考案は、上記従来の問題点に鑑みてなされたものであって、車輪とレールの 磨耗、騒音の低減、および曲線路における走行安定性と速度向上とをはかり、し かも蛇行動に対する安定性を損なわない鉄道車両用台車を提供することを目的と するものである。The present invention has been made in view of the above-mentioned conventional problems, and aims at wear of wheels and rails, reduction of noise, and stability and speed improvement of running on a curved road. The purpose of the present invention is to provide a bogie for railway vehicles that does not impair the stability of the railway car.

上記諸課題を解決するために、考案者は、一対の輪軸が台車枠の前後に配され 、それらの輪軸を保持する軸受収納の各軸箱が台車枠に対し上下、左右、前後方 向に移動可能に支持された鉄道車両用台車において、台車枠と車体、台車枠と輪 軸の各軸箱との間に両端がそれぞれ回転可能に支持されるとともに、油もれ補償 用の油タンクに接続されたシリンダBとシリンダAとが設けられ、シリンダBの ピストン両側はシリンダAのピストン両側とそれぞれ配管で接続され、シリンダ Bの断面積SB とこれに対応するシリンダAの断面積SA の比が、台車枠の縦方 向中心線からシリンダAの中心までの距離をl2 、一対の台車枠中心間の距離を BB、台車枠の縦方向中心線からシリンダBの中心までの距離をl1 、台車枠の 輪軸間の距離をWBとしたとき、 SB /SA =(2l2 ・WB)/(l1 ・BB) の関係を満たすように定められたことを特徴とする鉄道車両用台車を考案した 。In order to solve the above-mentioned problems, the inventor has found that a pair of wheel shafts are arranged in front of and behind the bogie frame, and that the bearing housings for holding these wheel shafts are vertically, horizontally and front-rearward with respect to the bogie frame. In a movably supported bogie for rail cars, both ends are rotatably supported between the bogie frame and the vehicle body, and between the bogie frame and each axle box of the axle, and an oil tank for oil leak compensation is provided. A connected cylinder B and a cylinder A are provided, and both sides of the piston of the cylinder B are connected to both sides of the piston of the cylinder A by pipes, respectively, and a sectional area S B of the cylinder B and a corresponding sectional area S A of the cylinder A are provided. the ratio of the distance a distance from the longitudinal direction centerline of the truck frame to the center of the cylinder a l 2, the distance between the pair of bogie frame center BB, from the longitudinal center line of the bogie frame to the center of the cylinder B L 1 and the distance between the axles of the bogie frame is W Assuming that B , S B / S A = (2l 2 · WB) / (l 1 · BB) is defined as satisfying the relationship, and a bogie for a railway vehicle was devised.
【0007】[0007]
鉄道車両が軌道曲線部にさしかかると、車両前部の台車枠は、車両に対し軌道 の曲線部と同じ方向に回転し、車両は、車両後部の台車枠に対し軌道の曲線部と 同じ方向に回転する。これらの回転により、軌道の曲率中心側のシリンダBは伸 長する方向に移動され、シリンダBに接続された一対のシリンダA,Aはそれぞ れ収縮する方向に移動される。これと同時に、軌道の曲率中心と反対側のシリン ダBと一対のシリンダA,Aは曲率中心側のそれらと反対方向に移動されるため 、各台車枠の一対の輪軸は、曲率中心側で間隔が狭くなり、反対側で間隔が広い V字状となる(図6参照)。この場合において、シリンダAとシリンダBの対応 する部分の断面積SA ,SB は、台車枠の幅方向中心線がそれぞれ曲率中心を通 る方向に偏寄するとき、各台車枠の輪軸がそれぞれ曲率中心を通る方向に偏寄す るよう定められているため、軌道曲線部を通過する鉄道車両用台車の各輪軸は、 曲線部の軌道と自動整合する車輪により、軌道の曲率中心を通る方向に向けられ る。When a railroad car approaches a curved track section, the bogie frame at the front of the car rotates in the same direction as the curved section of the track with respect to the vehicle, and the car moves in the same direction as the curved section of the track with respect to the bogie frame at the rear of the vehicle. Rotate. By these rotations, the cylinder B on the side of the center of curvature of the track is moved in the extending direction, and the pair of cylinders A, A connected to the cylinder B are moved in the contracting directions. At the same time, since the cylinder B and the pair of cylinders A, A on the side opposite to the center of curvature of the track are moved in the opposite direction to those on the side of center of curvature, the pair of axles of each bogie frame is located on the side of center of curvature. The gap becomes narrower and the gap becomes wider on the opposite side, resulting in a V-shape (see FIG. 6). In this case, the cross-sectional areas S A and S B of the corresponding portions of cylinder A and cylinder B are such that when the center lines in the width direction of the bogie frame are deviated in the directions passing through the centers of curvature, Each wheel axle of the railroad car passing through the curved section of the track passes through the center of curvature of the track due to the wheels that automatically align with the track of the railway section, because they are determined to deviate in the direction of passing through the center of curvature. Directed in the direction.

Two bogies 1 and 1 for railway vehicles are provided in the front-rear direction of the vehicle body 12. FIG. 4 is a simplified plan view showing the relative relationship between the vehicle body 12 in the track curve portion and the pair of bogies 1 and 1 for railway vehicles provided in the front-rear direction thereof. The deviation angle θ 1 when the center line in the width direction of a pair of railcar bogies 1 and 1 passes through the center of curvature O of the track in the curve section of the radius of curvature R is the distance between the pair of bogie centers. When BB is the distance between the axles of the bogie frame 2 and WB, it is expressed by the following equation. θ 1 = Sin -1 (BB / 2R) Usually, since it is BB«2R, θ 1 = Sin -1 ( BB / 2R) ≒ BB / 2R ...... Figure 5 bogie for a railway vehicle in track curve section 1 FIG. 6 is a simplified plan view showing the relative relationship between the pair of wheel axles 5 and 5. In the trajectory curve portion of the radius of curvature R, the deviation angle θ 2 when each wheel axle 5, 5 passes through the center of curvature O of the trajectory is expressed by the following equation. θ 2 = Sin -1 (WB / 2R) Usually, since it is WB«2R, θ 2 = Sin -1 ( WB / 2R) ≒ WB / 2R ......
【0012】 式より、次式が成り立つ。 θ1 /θ2 =(BB/2R)/(WB/2R)=BB/WB ∴ θ2 =θ1 /(BB/WB) …… すなわち式より、曲率半径Rによって鉄道車両用台車1が偏寄角θ1 を生じ たとき、輪軸5に偏寄角θ2 =θ1 /(BB/WB)を生じさせると、輪軸5を 曲率中心に向けることができる。 鉄道車両用台車1の偏寄角θ1 に連動して輪軸5に偏寄角θ2 =θ1 /(BB /WB)を生じさせるために、台車枠2の左右の外側に配設される1個ずつのシ リンダB16と、2個ずつのシリンダA15,15が用いられる。From the equation, the following equation holds. θ 1 / θ 2 = (BB / 2R) / (WB / 2R) = BB / WB ∴θ 2 = θ 1 / (BB / WB) …… In other words, from the formula, the bogie 1 for railway vehicles is biased by the radius of curvature R. When the deviation angle θ 1 is generated and the deviation angle θ 2 = θ 1 / (BB / WB) is generated in the wheel shaft 5, the wheel shaft 5 can be directed to the center of curvature. It is arranged on the left and right outer sides of the bogie frame 2 in order to generate the deviation angle θ 2 = θ 1 / (BB / WB) on the wheel axle 5 in conjunction with the deviation angle θ 1 of the railcar bogie 1. One cylinder B16 and two cylinders A15, 15 are used.

Each pair of cylinders A15, 15 is arranged between the left and right outer sides of the bogie frame 2 and each wheel axle 5, 5 so that both ends thereof are rotatably supported. Both ends of the bogie frame 2 are rotatably supported between the left and right outer central portions of the bogie frame 2 and the vehicle body 12. Both sides of the piston A17 of each cylinder A15 are connected to both sides of the piston B18 of the cylinder B16 by pipes 19 and 19. Due to the fluid filled therein, the deviation angle θ 2 of the wheel set 5 is It is interlocked with polarized preferred angle theta 1 of the vehicle bogie 1.

Assuming that A / Si A = So B / Si B , the cross-sectional areas of the corresponding portions of the two cylinders A15 and B16, for example, the ratio of Si B to Si A , are defined by the following equation. Si B / Si A = (2l 2 · WB) / (l 1 · BB)
【0014】 軌道曲線部における鉄道車両用台車1の動作を説明する。 図6と図8は、左カーブの軌道曲線部における車両前部の鉄道車両用台車1の 斜視図と要部平面図を示す。 軌道曲線部において、車体12が矢印P方向へ偏寄角θ1 だけ回転し(鉄道車 両用台車1は車体12に対し偏寄角θ1 だけ反対方向へ相対的に回転する)、鉄 道車両用台車1の幅方向の中心線が軌道の曲率中心Oを通る場合(図4参照)に は、シリンダB16は、基端側の室20の容積が減少する方向に移動される。 シリンダB16の基端側の室20から押し出された流体は、配管19を通して シリンダA15,15の基端側の室21,21に入る。これに伴い、シリンダA 15,15の先端側の室22,22から押し出された流体は、配管19を通して シリンダB16の先端側の室23に入り、曲率中心側の輪軸5,5間の間隔が狭 められる。The operation of the railcar bogie 1 in the track curve section will be described. FIG. 6 and FIG. 8 show a perspective view and a plan view of main parts of the railcar bogie 1 in the front part of the vehicle in the track curve section of the left curve. At the curve section of the track, the car body 12 rotates in the direction of arrow P by the deviation angle θ 1 (the railway vehicle trolley 1 rotates in the opposite direction relative to the car body 12 by the deviation angle θ 1 ), and the railway vehicle When the center line of the carriage 1 in the width direction passes through the center of curvature O of the track (see FIG. 4), the cylinder B16 is moved in the direction in which the volume of the chamber 20 on the base end side decreases. The fluid extruded from the chamber 20 on the base end side of the cylinder B16 enters the chambers 21, 21 on the base end side of the cylinders A15, 15 through the pipe 19. Along with this, the fluid pushed out from the chambers 22 and 22 on the tip end side of the cylinders A 15 and 15 enters the chamber 23 on the tip end side of the cylinder B 16 through the pipe 19, and the gap between the wheel shafts 5 and 5 on the curvature center side is Narrowed.
【0015】 車体12が矢印P方向へ偏寄角θ1 だけ回転すると、シリンダB16の基端側 の室20から押し出される流体の容積は、 SiB ・l1 ・θ1 …… この流体によって同一形状の2つのシリンダA15,15のピストンA17, 17が移動されるから、各ピストンA17,17の移動量は、 SiB ・l1 ・θ1 ・(1/2)・(1/SiA ) …… シリンダA15のピストンA17が式だけ移動されると、輪軸5は長さ方向 の中心のまわりに次式で示す角度θだけ回転される。 θ=SiB ・l1 ・θ1 ・(1/2)・(1/SiA )・(1/l2 )……When the vehicle body 12 rotates in the direction of the arrow P by the deviation angle θ 1 , the volume of the fluid pushed out from the chamber 20 on the base end side of the cylinder B 16 is Si B · l 1 · θ 1 ... Since the pistons A17, 17 of the two shaped cylinders A15, 15 are moved, the amount of movement of each piston A17, 17 is as follows: Si B · l 1 · θ 1 · (1/2) · (1 / Si A ) ... When the piston A17 of the cylinder A15 is moved by the formula, the wheel shaft 5 is rotated around the center in the longitudinal direction by the angle θ shown by the following formula. θ = Si B · l 1 · θ 1 · (1/2) · (1 / Si A ) · (1 / l 2 ) ……
【0016】 本考案の鉄道車両用台車1では、SiB /SiA は式の如く定められている から、式に式の関係を代入すると、 θ=(WB/BB)・θ1 ……a この偏寄角θは、式に示す偏寄角θ2 に等しいから、曲率半径Rの軌道曲線 部を通過する輪軸5は、常に軌道の曲率中心Oを通ることになる。In the railcar bogie 1 of the present invention, since Si B / Si A is determined by the equation, if the equation relationship is substituted into the equation, θ = (WB / BB) · θ 1 ...... a Since this deviation angle θ is equal to the deviation angle θ 2 shown in the equation, the wheel shaft 5 passing through the trajectory curve portion of the radius of curvature R always passes through the curvature center O of the trajectory.
【0017】 車体12が矢印P方向に偏寄角θ1 だけ回転した場合、軌道の曲率中心Oから 遠い側のシリンダB16から押し出される流体は先端側の室23となり、この流 体によって移動されるシリンダA15,15のピストンA17,17の移動方向 は、曲率中心Oに近い側のシリンダA15,15のピストンA17,17と逆に なり、各輪軸5は長さ方向の中心のまわりに同じ方向に偏寄角θ2 だけ回転され る。When the vehicle body 12 rotates in the direction of the arrow P by the deviation angle θ 1 , the fluid pushed out from the cylinder B 16 on the side far from the center of curvature O of the track becomes the chamber 23 on the tip side and is moved by this fluid. The movement directions of the pistons A17, 17 of the cylinders A15, 15 are opposite to those of the pistons A17, 17 of the cylinders A15, 15 on the side closer to the center of curvature O, and the respective wheel axles 5 are in the same direction around the center in the longitudinal direction. It is rotated by the deviation angle θ 2 .
【0018】 なお、前記式の要件は、鉄道車両用台車1が偏寄角θ1 、輪軸5が偏寄角θ 2 だけ回転したときに、1つのシリンダB16から押し出される流体の容積が2 つのシリンダA15に流入される流体の容積と丁度等しくなるようにして定めら れた。この場合、シリンダA15,B16のそれぞれについて、先端側の断面積 と基端側の断面積の比は一定に保たれている。It should be noted that the requirement of the above equation is that the railcar bogie 1 has an offset angle θ1, The wheel axle 5 has a deviation angle θ 2 It is determined that the volume of the fluid pushed out from one cylinder B16 is exactly equal to the volume of the fluid introduced into the two cylinders A15 when it is rotated by only one. In this case, the ratio of the cross-sectional area on the distal end side to the cross-sectional area on the proximal end side of each of the cylinders A15 and B16 is kept constant.
