Description

  The present invention relates to a vehicle body tilt control device for a railway vehicle that controls the vehicle body tilt by supplying and exhausting air springs when passing a curve.

  When passing a curve, the body of the railway vehicle may be tilted to the outer gauge side due to excessive centrifugal force, resulting in poor ride comfort. In particular, when passing a curve at a high speed, the excessive centrifugal force increases, resulting in further deterioration in riding comfort. Therefore, various types of vehicle body tilt control devices have been developed that prevent excessive centrifugal force from being deteriorated by inclining the vehicle body toward the inner track side when passing through a curve.

  Among these, in an apparatus that controls the inclination of the vehicle body by supplying and exhausting air to the left and right air springs that support the vehicle body, for example, as shown in FIG. And a pressure source 4 that is an air source are connected by two series of pipes 5a and 5b.

  In one of these pipes 5a, air supply valves 7aa to 7ab, 7ba to 7bb and exhaust valves 8aa to supply and exhaust air springs 3a and 3b based on the detection values of the height sensors 6a and 6b. 8ab and 8ba-8bb are installed.

  The other pipe 5b is provided with height adjusting valves 9a and 9b for maintaining the height of the air springs 3a and 3b at a neutral position during non-tilt control, and these height adjusting valves 9a and 9b during vehicle body tilt control. Switching valves 10aa to 10ab and 10ba to 10bb to be invalidated are installed (for example, refer to the background art of Patent Document 1).

  In the example of FIG. 3, in order to supply and exhaust air to the air springs 3a and 3b in stages, two air supply valves 7aa to 7ab and 7ba to 7bb and two exhaust valves 8aa to 8ab and 8ba to 8bb are provided. Yes. In addition, two switching valves 10aa to 10ab and 10ba to 10bb are provided in parallel for fail-safe vehicle body tilt control.

  By the way, as shown in FIG. 4, in the conventional vehicle body tilt control device, the switching valves 10aa to 10ab and 10ba to 10bb are supplied with the supply valves 7aa to 7ab and 7ba to 7bb and the exhaust valves 8aa to 8ab and 8ba to 8bb. It was housed in the same electromagnetic valve box 11.

  However, since the electromagnetic valve box 11 is usually installed at a distance from the air springs 3a and 3b, the height adjusting valves 9a and 9b and the switching valve disposed in the vicinity of the air springs 3a and 3b are often used. The piping paths of 10aa to 10ab and 10ba to 10bb are complicated, which is disadvantageous in terms of design and maintenance.

  The problem to be solved by the present invention is that, conventionally, a switching valve is also housed in an electromagnetic valve box that houses an air supply valve and an exhaust valve. The piping route is complicated, which is disadvantageous in terms of design and maintenance.

  The present invention adopts the following configuration in order to simplify the piping path between the height adjusting valve and the switching valve and eliminate the disadvantages in terms of design and maintenance.

That is, the vehicle body tilt control device for a railway vehicle of the present invention is
In the device for controlling the tilt of the vehicle body by supplying and exhausting air springs provided on the left and right sides between the vehicle body and the carriage,
A height adjustment valve for maintaining the height of the air spring at the time of non-tilt control, and a height adjustment valve provided in a pipe connecting the respective air springs and a source pressure source for storing gas supplied to the air springs. A switching valve that is provided in series with the valve and is closed when the vehicle body is tilted to disable the height adjustment valve; an exhaust valve that controls exhaust from the air spring; and a supply that controls air supply to the air spring Among the air valves, the most important feature is that the switching valve is housed in an equipment box containing a height adjustment valve, not an electromagnetic valve box containing an air supply valve and an exhaust valve.

  In the present invention, since the switching valve is housed in the equipment box containing the height adjustment valve, not the electromagnetic valve box containing the air supply valve and the exhaust valve, the piping path between the height adjustment valve and the switching valve Is simplified, and the disadvantages in terms of design and maintenance can be eliminated.

  In the present invention, by placing the switching valve in the equipment box containing the height adjustment valve, the piping path between the height adjustment valve and the switching valve can be simplified, eliminating the design disadvantages of maintenance. In addition, the solenoid valve box can be downsized.

It is the schematic block diagram which showed the principal part structure of the vehicle body tilt control apparatus of the railway vehicle of this invention. The left side of the drawing is a side view, the right side of the drawing is a front view, (a) is a manifold of a conventional device, and (b) is a view showing a manifold of the device of the present invention. It is a figure explaining the railway vehicle carrying the conventional vehicle body tilt control apparatus. It is the schematic block diagram which showed the principal part structure of the vehicle body tilt control apparatus of the conventional railway vehicle.

  The purpose of the present invention is to simplify the piping path between the height adjustment valve and the switching valve and eliminate the disadvantages in terms of design and maintenance. Rather, it was realized by placing it in an equipment box containing a height adjustment valve.

  Hereinafter, examples for carrying out the present invention will be described with reference to FIGS. 1 and 2 along with the progress from the new idea of the present invention to the solution of the problem.

  In the case of a railway vehicle equipped with a vehicle body tilt control device, the height adjustment valves 9a and 9b are often integrated with the height sensors 6a and 6b and stored in the equipment box 12.

  If the inventor houses the switching valves 10aa to 10ab and 10ba to 10bb inside the device box 12, it is not necessary to house the switching valves 10aa to 10ab and 10ba to 10bb inside the electromagnetic valve box 11, and the piping is simplified. The electromagnetic valve box 11 is thought to be downsized.

  In particular, when the height adjusting valves 9a and 9b are attached to the manifold 13 as shown in FIG. 2 (a), it is considered easy to enlarge the manifold 13 and provide a space for installing the switching valves 10a and 10b.

  As a result of studying the conventional manifold 13, the inventor has found that the two switching valves 10aa to 10ab or 10ba to 10bb can be installed in parallel only by increasing the lateral width by about 70 mm and the height by about 25 mm (FIG. 2). (See (b)).

  In FIG. 2, 13a is a supply port for the height adjusting valves 9a and 9b, 13b is a port for the air springs 3a and 3b, 13c is a port for the switching valves 10aa to 10ab or 10ba to 10bb, and 13d is a plug.

  The present invention has been made on the basis of the examination result based on the above-mentioned new idea. The switching valves 10aa to 10ab and 10ba to 10bb provided on the other pipe 5b connecting the air springs 3a and 3b and the original pressure failure are provided. It is characterized by being housed in the equipment box 12 containing the height adjusting valves 9a and 9b instead of the electromagnetic valve box 11.

  It is possible to accommodate the switching valves 10aa to 10ab and 10ba to 10bb in the device box 12 by adopting, for example, the manifold 13 shown in FIG.

  When the switching valves 10aa to 10ab and 10ba to 10bb are housed in the equipment box 12 instead of the electromagnetic valve box 11 as in the present invention, the height adjusting valves 9a and 9b and the switching valves 10aa to 10ab and 10ba to 10bb Can be greatly shortened and simplified (see FIG. 2B).

  Therefore, compared to the conventional device in which the switching valves 10aa to 10ab and 10ba to 10bb are housed in the electromagnetic valve box 11 separated from the height adjustment valves 9a and 9b, the design and maintenance of the piping path are facilitated. Maintenance disadvantages can be eliminated.

  In addition, the electromagnetic valve box 11 can be miniaturized because a space for accommodating the switching valves 10aa to 10ab and 10ba to 10bb is not necessary.

  Needless to say, the present invention is not limited to the above-described examples, and the embodiments may be appropriately changed within the scope of the technical idea described in the claims.

  For example, in the above example, for the fail-safe of the vehicle body tilt control, an example in which two switching valves 10aa to 10ab and 10ba to 10bb are provided in parallel is shown. However, even one switching valve may be provided. good. In this case, the installation space for the switching valve to the equipment box 12 (manifold 13) can be reduced.
