しているのが一般的である。2. Description of the Related Art In electric locomotives, electric diesel locomotives, etc., a large air blower is installed in the locomotive to send cooling air to a main motor incorporated in a traveling device, so that an independent hollow duct is provided. It is common to sew between various devices and arrange them on or under the floor.

て前記センターシルを使用したダクトを説明する。With respect to such a duct, in some locomotives, a center sill, which is a strength member of a vehicle body frame, is mounted in a center sill of a crossing portion which crosses a cross beam or the like and is important in terms of strength. In addition, an opening is provided in the nodular reinforcement of bamboo, and the cooling air that has passed through the opening as an orifice is branched to flow into a main motor or the like. A duct using the center sill will be described with reference to FIG.

センターシル１内には複数の整風ガイド８が設けられて
冷却風を分配している。The underframe has a center sill 1 at the center in the longitudinal direction, underframe side beams 2 are attached to both left and right sides, and an end beam 3 connects the above three members at the end of the vehicle body. Between the center sill 1 and the beam 2 on the underframe side, a pillow beam 4 is arranged on the upper part of the bogie part, and a plurality of horizontal beams 5 are arranged in the other part corresponding to the load on the floor, and the floor plate is installed on the above. Is configured.
An electric blower 6 is installed on the floor, and cooling air is blown to the main electric motor to the center sill 1 via a blower duct 7.
A plurality of air conditioning guides 8 are provided in the center sill 1 to distribute the cooling air.

【発明が解決しようとする課題】センターシルを冷却風
用ダクトとする構造において、主電動機冷却風を多量に
送風するためには、センターシルの節形補強の開口部を
大きくすることが必要であるが、節形補強中央の穴を大
きくしていくと、冷却風の圧力損失は小さくなるが補強
としての機能は次第に弱くなる。In the structure in which the center sill is used as the cooling air duct, in order to blow a large amount of the main motor cooling air, it is necessary to enlarge the opening of the nodal reinforcement of the center sill. However, if the hole at the center of the node-shaped reinforcement is enlarged, the pressure loss of the cooling air becomes smaller, but the function as reinforcement gradually becomes weaker.

冷却風ダクトとしては途中に補強材が無く、平な内面で
あることが要求される。本発明は、上記に鑑み車体台枠
の強度と、内面が平滑な冷却風用のダクトであるとの相
反する要求に対応できる車体台枠構造を目的とする。Since the body underframe is sandwiched between the equipment on the floor and the equipment under the floor, it is required to have sufficient strength.
The cooling air duct is required to have a flat inner surface without a reinforcing material in the middle. In view of the above, the present invention has an object of a vehicle body underframe structure that can meet the contradictory requirements of the strength of the vehicle body underframe and the duct for cooling air having a smooth inner surface.

補強材９を設ける。The center sill 1 includes an upper plate 1A, side plates 1C and 1C.
D and the lower plate 1B form a quadrangular shape, but the lower plate 9A made of a flat plate of the reinforcing material 9 provided inside is formed into a mountain shape,
Both lower ends are welded and fixed to the side plates 1C, 1D lower joint 10A. The same inverted mountain-shaped upper plate 9B is arranged on the mountain-shaped lower plate 9A, the lower and upper plates 9A and 9B are welded back to back, and both ends of the upper plate 9B are the upper corners 1C of the side plates 1C and 1D.
A corner welding is performed on 0C, an upper plate 1A is welded and covered, and a cross-sectional X shape is formed as a whole, and a reinforcing member 9 having a truss structure is provided in the center sill 1.

四辺形に変形し、台枠も破損してしまこともあり得た。As shown in FIG. 3, the center sill 1 is conventionally used.
When using as a duct, the nodal reinforcement 12 is provided in the center sill 1 that is joined to the transverse beam 5 that is a strength member and is passed through the cooling air hole 13, but when a large load is applied to the transverse beam 5 side. As shown in FIG. 4, the cross section of the center sill 1 was transformed into a parallelogram, and the underframe could be damaged.

又、前記山形の下板１０Ａ、上板１０Ｂを強固にすれば
水平補強板１５を省略することも可能である。As another embodiment of the present invention, the example shown in FIG. 5 is a case where the abutting joint portion of the cross beam 14 to the center sill 1 is attached in the middle of the side plates 1C, 1D of the center sill 1. In this case, in the conventional case, not only the center sill 1 is deformed into a parallelogram, but also when a load is applied to the horizontal beam 14, the side plate 1C is deformed into a dogleg shape, which makes it impossible for the horizontal beam 14 to handle the load. In the present invention, the horizontal reinforcing plate 15 is arranged in the center sill 1 at the joining position where the horizontal beam 14 abuts on the center sill 1, and two sets of the mountain-shaped lower plates 1 are provided above and below the horizontal reinforcing plate 15.
0A and the upper plate 10B are combined to form a truss-shaped member having two upper and lower stages, and a strong reinforcing structure is used.
Further, if the mountain-shaped lower plate 10A and the upper plate 10B are strengthened, the horizontal reinforcing plate 15 can be omitted.
