[0016]

Embodiments of the present invention will be described below. FIG.
1 is a side cross-sectional view schematically illustrating a configuration of a bogie with a vehicle body tilting device for a railway vehicle according to an embodiment of the present invention. FIG. 2 shows FIG.
It is a front view which shows typically the structure of the vehicle body inclination apparatus for railway vehicles of the same Example as FIG. (A) is a view on arrow AA in FIG. 1, and (B) is a view on arrow BB in FIG. 1.

The bogie 1 is composed of a wheel set assembly 8, a bogie frame (side beams 7, side beams 6), a pendulum beam 4, and the like. The wheel 43 is supported by an axle bearing 45 in an axle box (bearing box) 47 via an axle 49. The shaft box 47 is elastically supported by the side beam 7 via the shaft spring 41. The wheel 43, the axle 49, the axle bearing 45, and the axle box 47 are referred to as the axle assembly 8. The left and right two side beams 7 and the two front and rear side beams 6 are firmly fixed (welding or the like) and constitute a bogie frame. The bogie frame is mounted on a total of two wheelset assemblies 8 before and after.

The pendulum beam 4 is a hollow box-shaped beam having a partially arc-shaped lower end profile. An arc-shaped bearing guide rail 23 is fixed to the side surface of the inner wall of the hollow / box-shaped pendulum beam 4. Bearing guide rail 2
3 is slidably supported by the bearing block 21 via the bearing ball 22. The swing of the pendulum beam is driven and controlled by a vehicle body tilt control cylinder 11 and a vehicle body tilt control valve 12 directly attached to the vehicle body tilt control cylinder. On the pendulum beam 4, pillow spring 3
The vehicle body 2 is placed on the pillow spring 3.

The features of the pendulum truck of this embodiment when compared with the conventional truck of FIG. 3 are that it has a rotary beam 5, a bearing guide 20, a vehicle body tilt control cylinder 11, a vehicle body tilt control valve 12, a vehicle body tilt. The swing support mechanism and the swing drive mechanism such as the suppression cylinder 17 are housed in the pendulum beam 4.

The rotary beam 5 is rotatable in a horizontal plane about a pin hole 31 provided at the center of the bogie frame (lateral beam 6). The center pin 29 protruding downward from the center of the lower surface of the rotary beam 5 becomes the center of rotation of the rotary beam 5 and rotates in the pin hole 31. The slide receiving portion 33 supports both ends of the rotary beam 5 slidably from below.

The rotating beam 5 absorbs a rotational displacement (rotational displacement) between the bogie frame (lateral beam 6 and side beam 7) and the vehicle body 2 when the vehicle travels on a curved line.

In the conventional bogie shown in FIG. 3, the relative rotational displacement between the bogie and the vehicle body during curved running is absorbed by the pillow spring 3, and the rotational resistance of the bogie at that time is reduced by the yaw damper 1.
09. The reason why the rotary beam 5 is adopted as in this embodiment is that, as shown in FIG. 1, the lower portion of the pendulum beam 4 which supports the bearing guide 20, the vehicle body tilt control cylinder 11, and the like and is opened to incorporate such components. This is because it is useful as a member for closing the opening. Further, in the conventional bogie shown in FIG. 3, a single link 111 is employed to transmit the traction force between the vehicle body and the pendulum beam. However, this single link is longer than the front and rear width of the pendulum beam, This link presses down snow attached to the bogie when the car body is tilted, which is one of the causes of the malfunction of the car body tilting operation of the pendulum car. The rotating beam method was adopted, and one link was omitted.

Next, the structure of the pendulum beam 4 will be described.
The bearing block 21 is fixed to the bearing guide support 25 on the rotary beam 5 by bolts (not shown). This bearing block 21 is provided with a bearing guide rail 23 via a bearing ball 22.
Are slidably fitted. As shown in FIG. 2A, the bearing guide rail 23 is provided so as to draw an arc having a radius R centered on the vehicle body inclination center. Accordingly, the pendulum beam 4 swings on the rotating beam 5 so that the swing swings left and right. The bearing block 21, the bearing balls 22, and the bearing guide rails 23 form a bearing guide 20 as a swing support mechanism.
To form The bearing guide 20 itself is the same as the conventional one shown in FIG.

It is the vehicle body tilt control cylinder 11 that drives the pendulum beam 4 to swing with respect to the rotary beam 5. The vehicle body tilt control cylinder 11 is attached to a cylinder post 15 that rises up from the rotary beam 5. The tip of the rod of the vehicle body tilt control cylinder 11 is fixed to an arm 13 projecting from the pendulum beam 4. Therefore, the pendulum beam 4 swings right and left on the rotary beam 5 according to the change in the length of the rod of the vehicle body tilt control cylinder 11.

The vehicle body tilt suppressing cylinder 17 is also housed in the pendulum beam 4 like the vehicle body tilt control cylinder 11.
The vehicle body inclination suppressing cylinder 17 is used when the traveling speed is low,
In order to hold the vehicle body in the neutral position in the event of control failure, a pair of vehicle body tilt suppression cylinders mounted opposite to the pendulum beam 4 or the rotating beam 5 is used to rotate the former pendulum beam. Pendulum stopper 1 on beam 5
6, the pendulum beam 4 is fixed by inserting a pendulum stopper on the pendulum beam 4 in the case of the latter rotary beam mounting.

As shown in FIG. 1, a seal 27 is provided on a gap 26 between the rotary beam 5 and the pendulum beam 4. The seal 27 prevents snow or the like from entering the pendulum beam 4 from the gap 26. Further, bellows 28 (FIG. 2) for preventing invasion of snow and the like are provided in the openings at the left and right ends of the pendulum beam 4.

In FIG. 2, the vehicle body lower protrusion 51 and the lateral movement stopper 53 shown on the pendulum beam 4 regulate the lateral movement of the vehicle body 2 with respect to the pendulum beam 4. It is possible to keep a certain fixed limit (if the vehicle goes out of this limit,
For example, it may come into contact with the home or the inner wall of the tunnel).

Although not shown in FIGS. 1 and 2, in an actual bogie, brakes and bolster anchors (traction devices)
Known devices such as the above are provided as needed.

[0029]

As described above, the bogie with a vehicle body tilting device for a railway vehicle of the present invention exhibits the following effects. Since the rocking support mechanism such as a bearing guide and the rocking drive mechanism such as the vehicle body tilt control cylinder are housed inside the box-shaped pendulum beam, malfunction of the vehicle body tilting device caused by snow intrusion and icing can be prevented. Can be prevented. Since the pendulum beam itself is a snowproof cover structure, no extra structure is required, and there is no problem in design and maintenance. A control valve is mounted on the control cylinder body that controls the body tilt, and the control cylinder and the control cylinder are housed together in a pendulum beam, eliminating the piping between the control valve and the control cylinder. Responsiveness and controllability have been improved.
