る。2. Description of the Related Art Conventionally, a bogie frame for a railway vehicle has been considered as a frame structure using a fiber-reinforced resin composite material, such as a carbon fiber-reinforced resin composite material (hereinafter simply referred to as CFRP). An example of the bogie frame is JP-A-56-907.
71, JP-A-61-143257 and JP-A-62-24
4755 etc. Of these, JP-A-56-9077
1 uses a fiber-reinforced material for the bogie frame, which is H when viewed from the top.
It is constructed by arranging members in a letter shape, and the left and right ends of the H shape are combined with the axle at four locations. This makes it possible to utilize a part of the bogie frame as a primary spring member, connect the wheel set and the cross member without any joints, and reduce the weight. Furthermore, JP-A No. 61-143257 uses CFRP to construct a bogie frame with bending rigidity comparable to the spring constant of the shaft spring, and omit the shaft spring and damper to reduce the weight of the bogie frame. . Here, the bending rigidity of the bogie frame is determined by the cross-sectional shape,
The plate thickness and fiber orientation angle are selected and adjusted. Japanese Patent Application Laid-Open No. 62-244755 discloses a side beam made of composite material constituting a bogie frame, in which the side beam is constructed by combining several types of plate materials and foam to improve bending strength and load stability.

Since the beams and the plates that connect the beams are individually molded, the entire structure can be easily manufactured by simply joining them together. In addition, when a bending or torsional load is applied to each beam of the structure, since each beam is individually formed, its own strength is highly reliable, and each beam is joined by an integrally formed plate. This allows the load to flow smoothly at the joint, improving strength.

This is explained by: FIG. 1 is a perspective view of a bogie frame to which the present invention is applied, FIG. 2 is an enlarged view of the "A" part in FIG. 1, and FIG.
This is a 3-3 cross section. In the figure, 1 is a bogie frame, 2 is a side beam, 3 is a cross beam, 4 is a plate, 5 is a joint with an L-shaped cross section (hereinafter referred to as L-shaped joint), and 6 is a bolt/nut. The side beams 2, cross beams 3, and plate materials 4 are made of carbon fiber reinforced resin composite material (hereinafter simply CF), which is one of fiber reinforced resin composite materials.
RP). In this example,
First, the side beams 2 and cross beams 3 each having an I-shaped cross section are individually preformed using CFRP. In addition, in parallel with this, CFRP plates 4 are preformed to be disposed on the upper and lower flange portions of the side beams 2 and cross beams 3, respectively. Here, the main orientation Y of the carbon fibers in the plate material 4 is such that it crosses the joint boundary X between the side beam 2 and the cross beam 3, as shown in FIG. be considerate. Further, since the plate members 4 are arranged on the upper and lower surfaces of the side beams 2 and cross beams 3, respectively, the stress against bending moment becomes maximum within the same cross section, even in the general area, for example. Therefore, the orientation of the carbon fibers in the entire plate material 4 is determined taking these factors into account, and the entire plate material 4 is integrally formed. Here, the overall size and shape of the plate material 4 is such that it overlaps the entire upper and lower flange surfaces of the side beam 2 and the cross beam 3.

L-shaped joints 5 are provided on the web surfaces of the side beams 2 and cross beams 3, and are connected with bolts and nuts 6 as shown in FIG. Depending on the magnitude of the applied load, this L-shaped joint 5 can be fixed with a jig together with other parts during the main molding of the bogie frame 1, and can be integrally molded without using bolts and nuts 6.

も向上する。[0012] In the bogie frame 1 having such a member structure,
When a vertical load is applied to the side beam 2, most of the bending moment generated in the side beam 2 is borne by the integrally formed plate 4 and the flange portion 2a of the side beam 2. On the other hand, most of the shear force between the side beams 2 and the cross beams 3 is transmitted via the L-shaped joint 5 disposed between the two beams. In addition to these, lateral bending and torsional loads act on the bogie frame 1, but in any case, the bending load is applied to the plate material 4 mainly on the side beams 2 and 3, and the shear force between both beams is on the L-shaped joint 5. Force is transmitted throughout. In this case, large stress is generally generated at the joint between the side beam 2 and the cross beam 3. However, since these parts are provided with integrally molded plate material 4 and the manufacturing precision of the material itself is good, the allowable stress can be set high and the strength reliability is also improved.

Alternatively, similarly to the fourth embodiment, the joint portion of the longitudinal member 18 and the frame structure 19 that becomes the cross beam, that is, the web 20 on the side beam side of the web structure 20
T-shaped and L-shaped flat plate gussets 10 and 11 are arranged at the center of the joint between the web 20b and the cross beam side web 20b. Also,
Similar to the fifth embodiment, T-shaped and L-shaped gussets 10, 1
A long flat plate gusset 12 made of continuous gussets 1 is arranged. The frame structure 19 shown in FIG. 15 is entirely molded in one piece, but after being divided and molded at the top and bottom, a part 19e that becomes part of the side beam, or a part 19d that becomes part of the cross beam, the web structure is formed. 20 may be provided. In this case, the frame structure 19
This makes manufacturing and attachment to the web structure 20 easier than when the whole is integrally molded. As a result, in the bogie frame, the side beams are the longitudinal member 18, the frame structure 19, the web structure 20,
The cross beam is composed of a frame structure 19 and a part of the web structure 20. The joint portion between the side beam and the cross beam is formed in the process of combining each member to form the side beam and the cross beam. When such an external load acts on the bogie frame, the side beams cope with the load using the integrated rigidity of the longitudinal members, the frame structure, the web structure, and a portion of the plate material. The cross beam is handled by the integrated rigidity of the frame structure, web structure, and part of the plate material. At the joint between the side beam and the cross beam, the web 20 on the side beam and cross beam side of the web structure 20
Since a and 20b are welded together, the strength and reliability of the joint is improved compared to other embodiments.
