Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a railway vehicle carriage that can avoid interference of components as much as possible.
[0002]
[Prior art]
Some railcar trolleys are equipped with an anti-rolling device to prevent rolling of the vehicle body. As shown in FIG. 3, the anti-rolling device basically has a torsion bar 2 pivotally arranged between a pair of side beams 1 so as to be freely rotatable. One end of each of the attachment arms 3 is attached to each other, and the other ends of these attachment arms 3 are connected to the other end of the link 5 having one end attached to the vehicle body 4 in a pivotal manner. Note that reference numeral 6 in FIG. 3 denotes a lateral beam arranged at the front and rear to fix the side beam 1 at a position where it does not interfere with the wheel.
[0003]
[Problems to be solved by the invention]
Incidentally, the bogie for railway vehicles, and various brackets, pipe, cover or the like, since numerous components attached, is an important issue that the parts to each other this is found does not interfere.
[0004]
As described above, since a large number of parts are attached to the railcar bogie, it is difficult to prevent interference between parts even if an anti-rolling device is not attached. Therefore, in the narrow space between the bogie frame and the vehicle body, When mounting such an anti-rolling device, it is still difficult to prevent interference between parts.
[0005]
The present invention has been made in view of the above-described problems, and an object thereof is to provide a railway vehicle carriage that can avoid interference between components as much as possible even when an anti-rolling device is attached. Yes.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, the bogie for the railway vehicle according to the present invention includes a torsion bar of an anti-rolling device installed in the bogie for a railway vehicle inside the transverse beam. And by doing in this way, also when an anti-rolling apparatus is attached to the bogie for rail vehicles, interference between components can be avoided as much as possible.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The railway vehicle carriage according to the present invention is a railway vehicle carriage provided with side beams arranged on the left and right sides and two lateral beams arranged on the front and rear sides so as to fix the left and right side beams at positions that do not interfere with the wheels. The torsion bar of the anti-rolling device installed in the railway vehicle carriage is built inside the transverse beam.
[0008]
Since the railway vehicle carriage according to the present invention is configured as described above, even when an anti-rolling device is attached to the railway vehicle carriage to which a large number of parts are attached, interference between the parts can be avoided as much as possible. .
[0009]
【Example】
DESCRIPTION OF EMBODIMENTS Hereinafter, a railway vehicle carriage according to the present invention will be described based on an embodiment shown in FIGS.
FIG. 1 (a) is a perspective view for explaining the overall outline of a railway vehicle carriage according to the present invention, (b) is a partial view of (a) with the addition of a vehicle body, and FIG. It is a figure explaining the principal part outline of an aspect.
[0010]
In FIG. 1, reference numeral 11 denotes a yaw damper, for example, an oil damper, disposed horizontally in the same direction as the rail. For example, two are disposed on the outside of the side beam 1, one in total. Then, one end of these yaw dampers 11 is pivotally supported on the left and right ends of the torsion bar 2 supported so as to be freely rotatable by the side beam 1 constituting the carriage, and the other end is suspended from the vehicle body 4. For example, the damper receiving member 12 is pivotally connected via a rubber bush 13.
[0011]
The railcar bogie of the present invention passes the torsion bar 2 of the anti-rolling device to which the function of the above-described yaw damper is added, for example, through the transverse beam 6.
[0012]
In the railway vehicle carriage of the present invention configured as described above, the anti-rolling device torsion bar 2 passes through the cross beam 6, and therefore the anti-rolling device is further attached to the railway vehicle carriage to which a large number of parts are attached. In addition, interference between components can be prevented as much as possible.
[0013]
In the embodiment shown in FIG. 1, as an anti-rolling device, a damper receiving member in which a yaw damper 11 is used as an attachment arm, and an attachment arm, that is, an arm interposed between the yaw damper 11 and the vehicle body 4 is provided in a hanging manner from the vehicle body 4 12 shows the anti-rolling device added with the function of a yaw damper by being rigidly coupled to the vehicle body 4, but it goes without saying that the present invention is not limited to this.
[0014]
For example, in the embodiment shown in FIG. 1, a bending moment acts on the contact portion between the piston 11b of the yaw damper 11 and the cylinder 11a due to its configuration. To avoid this, as shown in FIG. The cylinder 11a and the vehicle body 4 may be connected by, for example, a link 14 so that the cylinder 11a and the piston 11b constituting the yaw damper 11 are restrained with one degree of freedom. In this way, when rolling occurs between the carriage and the vehicle body 4, the cylinder 11a and the link 14 bear a bending moment that applies torque to the torsion bar 2. Therefore, the damper receiving member on the vehicle body side 12 bears only the longitudinal load via the piston rod 11c.
[0015]
Further, it goes without saying that the railcar carriage of the present invention is also effective when an anti-rolling device having no yaw damper function as shown in FIG. 3 is installed.
[0016]
【The invention's effect】
As described above, in the railway vehicle carriage according to the present invention, the torsion bar of the anti-rolling device is passed through the cross beam, so that the anti-rolling device is attached to the railway vehicle carriage to which many parts are attached. In addition, interference between components can be prevented as much as possible.
