本発明は鉄道車輌用台車枠に係り、特に繊維強化プラス
チック（以下、ＦＲＰと称す）の積層体を用いて構成さ
れる台車枠構造の改良に関する。[Detailed Description of the Invention] [Object of the Invention 1] (Industrial Application Field) The present invention relates to a bogie frame for railway vehicles, and particularly to a bogie frame constructed using a laminate of fiber reinforced plastic (hereinafter referred to as FRP). This invention relates to improvements to bogie frame structures.
（従来の技術）
従来、鉄道車輌用台車枠は、鋼板を材料として製作され

６−９０７７１号公報、特開昭６１−１４３２５７号公
報に示されているように、ＦＲＰを用いた台車枠か開発
されている。(Prior art) Conventionally, bogie frames for railway vehicles have been manufactured using steel plates, but in recent years, due to the demand for weight reduction, for example,
As shown in Japanese Patent Laid-open No. 6-90771 and Japanese Patent Laid-Open No. 61-143257, bogie frames using FRP have been developed.
（発明が解決しようとする課題）
ところで、ＦＲＰで台車枠を構成する主目的は軽量化で
あるが、同時に、強度の確保および製造コストの低減が
必要となる。そして、そのためには、以下の点を考慮す
る必要がある。(Problems to be Solved by the Invention) By the way, the main purpose of constructing a bogie frame with FRP is to reduce weight, but at the same time, it is necessary to ensure strength and reduce manufacturing costs. In order to do so, it is necessary to consider the following points.
すなわち、部品点数を少なくし、かつ形状をシンプルに
することにより、特にＦＲＰ成形のための型費を低減す
る必要がある。That is, it is necessary to reduce the mold cost, especially for FRP molding, by reducing the number of parts and simplifying the shape.
また、鉄道車輌用台車枠は、特に車輌が線路上を走行す
る際に、レールの不整や曲線部のカント（左右レールの
高低差）等により捩られるため、側梁と横梁との結合部
の断面変形か急な場合には、高い応力集中が起こって破
壊に到るおそれがある。In addition, bogie frames for railway vehicles are twisted due to irregularities in the rails and cant of curved sections (difference in height between the left and right rails), especially when the vehicle runs on the track. If the cross-sectional deformation is sudden, high stress concentration may occur, leading to failure.
このため、強度上の観点から、特に側梁と横梁との結合
部に生じる応力集中を軽減する必要がある。Therefore, from the viewpoint of strength, it is necessary to reduce the stress concentration that occurs particularly at the joints between the side beams and the cross beams.

Ｐの強度を負担している強化繊維力を分断されるため、
著しい強度低下を招く。したがって、部品の取付は孔は
、主要部位を避けるか、別部品の補強材を追加する等の
処置か必要である。Furthermore, parts such as the axle springs that connect the wheels and the link device that transmits the load between the car body and the bogie must be attached to the bogie frame with bolts, but in the case of a bogie frame with an FRP structure. If a bolt hole is drilled in the hole, the FR
Because the reinforcing fiber force that bears the strength of P is divided,
This results in a significant decrease in strength. Therefore, when attaching parts, it is necessary to take measures such as avoiding holes in the main parts or adding reinforcing material for separate parts.
本発明は、かかる現況に鑑みなされたもので、構造が簡
単で部品点数も少なく、かつ組立てが簡単で高い強度が
得られ、しかも補強部材を追加することなく部品取付は
用の貫通孔を設けることができる鉄道車輌用台車枠を提
供することを目的とする。The present invention was developed in view of the current situation, and has a simple structure, a small number of parts, easy assembly, high strength, and a through hole for attaching parts without adding any reinforcing members. The purpose of the present invention is to provide a bogie frame for a railway vehicle that can be used in a railway vehicle.
