Description

The present invention relates to a railroad vehicle structure.

Generally, the floor of a railroad vehicle is configured by providing a floor surface portion via a support portion on a floor structure formed on an underframe. Since the vibration from the rail is transmitted from the floor structure to the floor surface portion via the support portion when the railroad vehicle is traveling, a technique for suppressing the vibration felt by passengers and the like in the vehicle interior is required. As such a technique, for example, in the floor surface support structure described in Patent Document 1, connecting members suspended from each of the left and right side structures are connected to the left and right ends of the floor surface portion divided into a plurality of parts in the longitudinal direction of the vehicle. There is. As a result, the floor surface portion has a suspended structure and can swing with respect to the floor structure.

Further, as shown in FIGS. 1 and 2, the railroad vehicle structure 1 includes a floor surface portion 21, a connecting member 22, and a regulating member 23. As shown in FIG. 2, the floor surface portion 21 is a portion constituting the floor surface of the passenger compartment S, and is used for the passage of passengers and the like and for fixing the seat 6. The floor surface portion 21 is arranged at a position above the floor structure 2 at a certain interval from the floor structure 2. In the present embodiment, the floor surface portion 21 is divided into rows of seats 6 arranged in the longitudinal direction of the vehicle. That is, a plurality of floor surface portions 21 are arranged in the longitudinal direction of the vehicle, and seats 6 in each row are installed on each floor surface portion 21. The adjacent floor surface portions 21 and 21 may be connected to each other by, for example, rivets, or may be connected to each other via an elastic member such as a sponge.

The connecting member 22 is a member that connects the side structure 3 and the floor surface portion 21. As the connecting member 22, for example, a wire, a rod-shaped member, a strip-shaped member, or the like can be used. The connecting member 22 may be formed of a metal material or a resin material such as carbon fiber reinforced plastic. The connecting member 22 may be a member having a certain elasticity in the longitudinal direction. As shown in FIG. 1, the connecting member 22 hangs down between the outer plate 11 and the inner plate 12 in each of the left and right side structures 3. Further, as shown in FIG. 2, the connecting members 22 are arranged at positions corresponding to the blow-in panel 15, and are arranged in pairs in the front-rear direction so as to sandwich the seat 6 with respect to the floor surface portion 21. The floor surface portion 21 is suspended from the side structure 3 by a total of four connecting members 22 in front, back, left and right, and can swing with respect to the floor structure 2.

In the present embodiment, the upper end portion 22a of the connecting member 22 is swingably coupled to the inner surface of the outer plate 11 at a position higher than, for example, the lower edge of the window 13. Further, the lower end portion 22b of the connecting member 22 is swingably coupled to, for example, the upper edge side of the side surface in the width direction of the floor surface portion 21.

Further, according to the suspended structure of the floor surface portion 21, the vibration damping effect due to the inertial force of the swinging floor surface portion 21 is also obtained. Therefore, the vibration caused by the elastic vibration of the side structure 3 can be effectively absorbed. Therefore, in the railway vehicle structure 1, the vibration and noise of the floor surface portion 21 can be effectively suppressed. Further, in the railway vehicle structure 1, the displacement of the connecting member 22 in the horizontal plane is regulated within a certain range by the regulating member 23. Therefore, excessive rocking of the floor surface portion 21 is suppressed, and the comfort of passengers and the like can be suitably maintained.

As a result, the arrangement position of the connecting member 22 is not obstructed by the window 13, and the degree of freedom in design can be ensured.

Further, in the railway vehicle structure 1, the side structure 3 includes the outer plate 11 and the inner plate 12, and the connecting member 22 is arranged between the outer plate 11 and the inner plate 12. By arranging the connecting member 22 between the outer plate 11 and the inner plate 12 in this way, it is possible to prevent the connecting member 22 from affecting the configuration inside the vehicle interior S.

Further, in the railway vehicle structure 1, the regulation member 23 is a ring-shaped member 31 fixed to the inner plate 12, and the connecting member 22 is passed inside the ring-shaped member 31. With such a configuration, the swing range of the connecting member 22 can be regulated by the regulating member 23 with a simple configuration.

Further, in the railway vehicle structure 1, the regulation member 23 is detachably fixed to the inner plate 12 by the surface fastener 32.
