。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device and method for controlling the longitudinal rigidity of the axle box support in accordance with track conditions in an axle box support device for a bogie for a railway vehicle.
【０００２】0002
【従来の技術】旅客車両の大型化と走行性能の向上に伴
い、台車はすべて２軸以上のボギー台車が使用されてお
り、車体の曲線通過が容易にできるように構成されてい
る。BACKGROUND OF THE INVENTION As passenger vehicles have become larger and their running performance has improved, bogies with two or more axles have been used for all bogies, and are constructed so that the vehicle body can easily pass through curves.
【０００３】鉄道車両は、曲線を通過するとき、車輪が
転動する方向とレールの方向が常に一致しておれば、ス
ムーズな曲線通過ができる。近年来そのための自己操舵
台車が研究されている。[0003] When a railway vehicle passes through a curve, if the direction in which the wheels roll and the direction of the rail always match, the railway vehicle can smoothly pass through the curve. Self-steering carts for this purpose have been researched in recent years.
【０００４】車軸をラジアル方向に自己操舵させるには
、一般に軸箱を前後方向に対し柔支持する必要がある。
しかし、一方、舵行動に対しては、前後方向に軸箱を剛
支持することが望ましい。したがって、この相矛盾する
特性を両立させる必要がある。[0004] In order to self-steering the axle in the radial direction, it is generally necessary to flexibly support the axle box in the longitudinal direction. However, on the other hand, for steering action, it is desirable to rigidly support the axle box in the longitudinal direction. Therefore, it is necessary to reconcile these contradictory characteristics.

置をとるような仕組みになっている。そして、直線路で
は互いにリンクによって拘束され剛支持となり、蛇行動
に有利とされている。[0005] Conventional self-steering bogies have a structure in which the front and rear wheel sets and axle boxes are each attached to a subframe, and the front and rear wheels are connected diagonally with cross anchors, so that one wheel set bends along the rail on a curve. When displacement occurs, the link action of the cross anchor forces the other wheel set to bend in the opposite direction, allowing the front and rear wheel sets to smoothly assume their radial positions. On a straight road, they are restrained by links and rigidly supported, which is said to be advantageous for meandering behavior.
【０００６】また、軸箱支持装置は、曲線路を安定して

である。そのため、従来より軸箱支持剛性を可変にして
輪軸の操舵を行なう機構が種々工夫されている。その中
の一つに図５に示す改良されたウイングばね型式の軸箱
支持装置がある。[0006] Furthermore, in order for the axle box support device to stably pass through curved roads, it is effective to reduce the support rigidity in the longitudinal direction. For this reason, various mechanisms have been devised in the past for steering wheel axles by varying the axle box support rigidity. One of these is an improved wing spring type axle box support device shown in FIG.

に当接する。That is, the shaft spring 18 is fitted into spring seats 17 provided at the front and rear of the shaft box 16, and a tapered hole 20 is provided in the spring seat 19 of the shaft spring. Further, a laminated rubber 21 is installed around the tapered hole 20. And laminated rubber 21
The upper surface abuts the lower surface of a support frame 23 provided on the side beam 22 of the truck.

気ばね３０を介在する。[0008] The support frame 23 is provided with a guide cylinder 25 on the upper part thereof, which slidably supports the upper end of the piston 24, and is fitted into the piston 24. A flange-shaped support member 27 is provided at the center of the piston 24, and a coil spring 29 is provided between a spring seat 28 provided on the support member 27 and the upper surface of the guide tube 25, and a support frame An air spring 30 for the steering device is interposed between the lower surface of the piston 23 and the piston support member 27.

常の直線高速走行に必要な支持剛性が与えられている。Pressure air is normally extracted from the air spring 30, and due to the restoring force of the coil spring 29, the tapered end portion 26 of the piston fits into the tapered hole 20 without any gap, providing the support rigidity necessary for normal straight-line high-speed running. It is being

部２６との間に隙間を生じさせる。When the stiffness in the longitudinal direction is reduced to obtain the steering performance necessary for passing through a curved road, the air spring 30 is filled with pressurized air to push up the piston 24 against the restoring force of the coil spring 29. , a gap is created between the tapered hole 20 and the tapered portion 26 of the piston.

った。The wing spring type box axle support device is rigidly supported when traveling on a straight road, and is flexibly supported in the longitudinal direction when traveling on a curved road, making it easier to travel on curved roads. However, the support rigidity can be changed by manually filling or extracting pressurized air into or from the air spring, and cannot be performed automatically.
