No. 9 ”Japan Railroad Vehicle Manufacturers Association P issued in August 1982
As shown in 29, etc., the side beams and cross beams were made of shape members, and the floor was constructed by laying a keystone plate. Such a conventional underframe structure will be described with reference to FIGS. 12 to 14. In the figure, 1 is an underframe, 2 is side beams arranged on both sides of the underframe 1, 3 is a lateral beam arranged between the side beams 2, and 4 is a keystone provided on the upper surface of the lateral beam 3. It is a plate. Reference numeral 5 is a pillow beam installed in parallel with the transverse beam 3 at a position corresponding to the vehicle body supporting device, and 6 is an end beam provided at the vehicle end portion of the underframe 1.

が顕著になるという欠点があった。In such a structure, the weight of indoor fittings such as passengers and stools and the weight of various electric appliances are hung under the floor of the underframe 1, and most of the weight is borne by the horizontal beam 3. It was. Therefore, the cross beam 3 is generally about
It is arranged in the longitudinal direction of the car body at a pitch of 500 mm to 700 mm, and its cross-sectional shape gives U-shaped steel an appropriate height and cross-sectional area as shown in Fig. 14 in order to secure the rigidity and strength capable of holding the weight sufficiently safely. Was formed. However, the horizontal beam 3
The weight accounts for about 20% of the entire underframe 1, which is an obstacle to reducing the weight of the vehicle body. Also,
When a large number of various electric machines or various ducts are attached under the floor of the underframe 1, since the horizontal beam 3 is high in height, the space in which equipment can be attached to the track is reduced and the attachment structure is complicated. In addition, it has to be installed by an upward work, and the workability is poor, and a great number of man-hours are required. Furthermore, underframe 1
If it is necessary to provide a heat insulating material on the lower surface of the whole surface, the space where equipment can be installed between the track and the track will be further reduced, and the above-mentioned increase in man-hours or complication of the mounting structure will be remarkable. there were.

FIG. 3 is a sectional view taken along the line A, and FIG. 3 is a sectional view taken along line B-B in FIG.
In the figure, the same reference numerals as those in the conventional example indicate the same members. Reference numeral 8 is a lateral beam having a box-shaped cross section, and 9 is a side beam having a flange portion 9a for receiving the lateral beam 8 at the center side of the vehicle body. The horizontal beam 8 is an alternative to the conventional horizontal beam, and is made of a thin plate by plastic working, and is composed of a flange portion 8a formed by opening the upper surface, a side surface 8c, and a lower surface 8d.
Reference numeral 10 denotes a joint portion that joins the lateral beams 8 when the lateral beams 8 are arranged between the side beams 9 so that the side surfaces 8c contact each other. The joining is performed by spot welding or the like. The underframe is composed of these members, and the assembling is first performed by the side beam 9, the pillow beam 5, and the end beam 6.
And the middle beam 7 is joined. Then, the transverse beams 8 are arranged in contact with the adjacent ones between the pillow beams 5 provided at the front and rear positions. At this time, the end portion 8b of each horizontal beam 8 is placed on the flange portion 9a of the side beam 9, and the adjacent horizontal beams 8 and the end portion 8b of the horizontal beam 8 and the side beam 9 are joined by welding or the like. In addition,
In the joining, an adhesive may be used together or a rivet or the like may be used.

施例の構成と同様な効果が得られる。According to such a configuration, since the cross beam 8 has a box-shaped cross section and its section modulus can be increased, its strength is high,
The plate thickness of the plate material forming the cross beam 8 can be reduced. Therefore, since the cross beam 8 can be made lighter, the weight of the entire underframe can be reduced as compared with the conventional one. Further, when the underframe is formed by the horizontal beam 8, it is not necessary to lay a keystone plate on the upper surface of the horizontal beam 8 and the floor plate can be directly attached, and the thickness of the underframe can be reduced. As a result, a sufficient device mounting space between the track and the underside of the underframe can be secured. Further, when it is necessary to dispose the heat insulating material on the floor surface, it is sufficient to insert the heat insulating material into the cross beam 8 by the downward work, and the workability thereof is higher than that of the conventional case where the heat insulating material is mounted on the lower surface of the underframe by the upward work. Can be significantly improved. In the case of mounting the device under the floor in the previous configuration, the side surface of the transverse beam 8 is cut back and a device support member is attached to this portion, and the device is supported by the support member. Further, in the above configuration, the keystone plate is provided from the bolster 5 to the vehicle end, but the transverse beam 8 is arranged to the vehicle end, and the strength members of the bolster 5 and the center girder 7 are provided as separate members. Even if it is installed under the floor, the same effect as that of the above-described embodiment can be obtained.

る。Next, a modified example of the lateral beam in the above-described embodiment will be described with reference to FIGS. As shown in FIG. 4, a reinforcing member 11 having a hat-shaped cross section is provided in the longitudinal direction at a position corresponding to the lower surface 8d inside the transverse beam 8. As shown in FIG. 5, a groove-shaped reinforcing portion 8e is formed on the lower surface 8d of the horizontal beam 8. What is shown in FIG. 6 is the lower surface inside the cross beam 8.
A reinforcing member 11 'having an L-shaped cross section is provided in the longitudinal direction at a position corresponding to 8d. According to such a configuration, the entire lower surface 8d of the horizontal beam 8 effectively acts to improve the strength, so that
The strength improvement can be achieved with a small weight increase.
In addition, as shown in FIGS. 7 and 8, the hat-shaped cross-section strength member 11 is arranged in the width direction at a position corresponding to the lower surface 8d inside the cross beam 8. With such a configuration, it is possible to prevent the lower surface 8d of the lateral beam 8 from being bent.

Is provided with a first side surface 8'c having a high height perpendicular to the lower surface at one end in the width direction of the lower surface 8d formed in a horizontal plane. A flange 8'a is formed at the upper end of the first side face 8'c so as to extend toward the widthwise center of the horizontal beam. At the other end of the lower surface 8d in the width direction, a second side surface 8'e having a height lower than that of the first side surface is formed perpendicularly to the lower surface. A large number of horizontal beams 8'having such a configuration are arranged in series and the first side face 8'c
At the time when the second side surfaces 8'e of the other horizontal beam are joined to each other, a box-shaped cross section is formed by the two adjacent horizontal beams 8 ', 8'. Therefore, the cross-sectional shape finally becomes the same, and the strength is close to that of the one embodiment. On the other hand, by lowering the second side surface 8'e on one side, the weight of the lateral beam 8'can be reduced, and the weight of the entire underframe can be further reduced as compared with the one in the above-mentioned embodiment. . Further, the number of manufacturing steps of the horizontal beam 8'can be reduced.

Join together. In the case of joining, the lower end portion of the side surface 8 "c and the both-end bent portion 8" f of the lower surface 8 "d are joined by spot welding, welding using an adhesive agent, rivets, or the like. Since the side surface 8 "c and the lower surface 8" d are completely separate members, it is possible to manufacture those having different plate thicknesses, and place and join them according to the applied load, and it is possible to achieve an appropriate rigidity arrangement. In addition, the weight of the entire underframe can be reduced by appropriate rigidity.

By leaving 12 open, the bending rigidity per unit weight can be increased, and the weight can be reduced.
