  However, in the case where the tilting device 105 is a roller mechanism as described above, the load is borne by a small surface, so that the vicinity of the neutral point of the rolling plate 104A of the tilting beam 104 is significantly worn, preventing smooth movement. .

  Even when a bearing guide is used, fretting wear occurs due to vibration during traveling, and the performance is degraded.

  In view of the above situation, the present invention provides a railway vehicle carriage provided with a pendulum device capable of realizing a smooth pendulum operation by providing an air static pressure guide mechanism in the railway vehicle carriage pendulum apparatus. For the purpose.

In order to achieve the above object, the present invention provides
[1] A railcar bogie is characterized in that an air static pressure guide mechanism is provided at a support portion of a pendulum beam of a railcar bogie equipped with a pendulum device.

  [2] In the railway vehicle carriage provided with the pendulum device according to [1], the static air pressure guide mechanism includes an opening on the carriage side for supplying compressed air to a support portion of the pendulum beam. And

  [3] In the railway vehicle carriage including the pendulum device according to [1], the static air pressure guide mechanism includes an opening for supplying compressed air to the pendulum beam support portion of the pendulum beam. Features.

  According to the present invention, the support portion of the pendulum beam becomes non-contact with the compressed air, or the compressed air bears a part of the load of the pendulum device, thereby reducing the rotational resistance of the pendulum beam, with a smaller force than before. The pendulum beam can be rotated. Since the pendulum beam support is non-contact, there is no wear. Or since the load with respect to a pendulum beam becomes small, it becomes possible to suppress the amount of wear small. Further, since the force for rotating the pendulum beam can be small, the pendulum device can be configured with a compact pendulum control cylinder having a smaller generated force.

  In the railway vehicle carriage provided with the pendulum device of the present invention, an air static pressure guide mechanism is provided at the support portion of the pendulum beam of the railway vehicle carriage provided with the pendulum device.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a diagram showing a railway vehicle carriage provided with a pendulum device according to the present invention, and FIG. 2 is a schematic view of a first static air pressure guide mechanism provided in the railway vehicle carriage of FIG.

  As shown in FIG. 1, on the side of the carriage A, 1 is an axle, 2 is a wheel, 3 is a carriage frame (side beam), 4 is a carriage frame (horizontal beam), 5 is an axle box support device, 6 is an axle box, 7 is a disc brake, 8 is a pendulum suppression cylinder, 9 is an SJ cylinder, 10 is an R guide receiver, and 11 is an R guide rubber. On the pendulum device B side, 21 is a pendulum beam, 22 is an air spring disposed on the left and right of the pendulum beam 21, 23 is a center pin, 24 is a pendulum damper, 25 is a yaw damper, 26 is a left-right damper, and 27 is a pendulum. The R guide of the beam 21, 28 is a single link, 29 is a stopper rubber holder, 30 is a pendulum control cylinder with a displacement gauge, and 31 is a snow cover. Such a pendulum device B is assembled to the carriage A to constitute a railway vehicle carriage including the pendulum device.

  Here, the pendulum device is a device for tilting the vehicle body inward of the curve in order to cancel the excess centrifugal force acting on the vehicle body when the vehicle passes through the curve.

  Here, the pendulum beam 21 is supported by the R guide 27 and the pendulum control cylinder 30 with a displacement gauge is operated to tilt the vehicle body. In the present invention, compressed air is supplied from the carriage A instead of the R guide 27 and the roller mechanism. An L-type static air pressure guide mechanism 41 as shown in FIG. 2 is provided to supply and lift the pendulum beam 21.

  The L-type static air pressure guide mechanism 41 is provided at the support portion of the pendulum beam 21 and supplies compressed air from an opening provided on the cart A side so as to support the pendulum beam 21.

  With this configuration, the support portion of the pendulum beam 21 is brought into a non-contact state by the compressed air, and the compressed air bears a part of the load of the pendulum device B, so that the rotational resistance of the pendulum beam 21 is reduced. Can do.

  In this embodiment, as shown in FIG. 3, a square air static pressure guide mechanism 42 that floats the pendulum beam 21 by supplying compressed air from the opening of the corner portion 21 </ b> A of the pendulum beam 21 is used. As a result, the support portion of the pendulum beam 21 is brought into a non-contact state by the compressed air, and the compressed air reduces the load of the pendulum device B. Therefore, the rotational resistance of the pendulum beam 21 is reduced, and the actuator having a smaller generation force is used. A pendulum device can be configured.

  Further, the support portion of the pendulum beam 21 is brought into a non-contact state by the compressed air, and a load to be applied is reduced, so that friction does not occur or the amount of wear can be suppressed to a small amount.

  2 and 3, the load of the pendulum beam 21 is supported only by the aerostatic pressure guide mechanisms 41 and 42. However, the load of the pendulum beam 21 can be combined with a conventional roller mechanism or a bearing guide mechanism. You may comprise so that one part may be borne.

  In addition, the static air pressure guide mechanism used in the present invention can be configured simply because it can use the compressed air conventionally used in railway vehicles.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The railway vehicle carriage provided with the pendulum device of the present invention can be used as a railway vehicle carriage capable of realizing a smooth pendulum operation.
