FIG. 5 is a cross-sectional view (DD cross-sectional view of FIG. 4) in the longitudinal direction of the carriage 30 and the vehicle body. 6 is a cross-sectional view in the longitudinal direction of the vehicle end portion (cross-sectional view taken along line EE in FIG. 4).

  As shown in FIG. 4, the underframe 50 includes side beams 52 and end beams 51 as a frame. The side beams 52 are arranged along the longitudinal direction 510 at both ends in the width direction 520, and the end beams 51 are arranged along the width direction 520 at both ends of the longitudinal direction 510. The pillow beam 54 is disposed as a part of the base frame 50 to which the carriage 30 is attached below, and is made of a rigid member having high rigidity. As shown in FIGS. 4 and 5, the center pin 56 is disposed on the lower surface of the central pillow beam located at the central portion in the width direction 520 of the pillow beam 54, and is an axis when the carriage 30 turns in a horizontal plane. Become. A pair of intermediate beams 53 are laid along the longitudinal direction 510 between the end beams 51 and the pillow beams 54 at both ends in the longitudinal direction 510 of the frame 50, and connect the end beams 51 and the pillow beams 54. .

  The two exhaust pipes 26 are extended from the internal combustion engine 24 via the silencer 27 and are raised to the lower surface of the central portion in the width direction 520 of the frame 50 in the vicinity of the internal combustion engine 24, and the width direction 520 (horizontal plane). Are arranged side by side (FIG. 3). Next, the two exhaust pipes 26 arranged side by side on the horizontal plane penetrate the pillow beam 54 along the longitudinal direction 510 (FIG. 5), and between the pair of middle beams 53 constituting the frame 50. It is laid (FIG. 4).

  The two exhaust pipes 26 extend to the vicinity of the end beam 51, and then merge to be integrated into one exhaust pipe 26 (FIG. 4). As shown in FIG. 6, the single exhaust pipe 26 is laid between a pair of middle beams 53 and is located below the coupler 58. At the same time, the exhaust pipe 26 is fixed to an exhaust pipe receiver 46 installed on the lower surface of the middle beam 53 via an anti-vibration support 47. Further, the exhaust pipe 26 extending to the vicinity of the end beam 51 is bent toward the end in the width direction 520 (FIG. 4), and in the height direction 530 along the vehicle inner surface of the wife structure (not shown). It is erected so as to extend through the roof structure (not shown). Normally, the inside of a wife structure vehicle is not a cabin space where passengers sit, but a deck section where passengers get on and off the railway vehicle, or an equipment room or luggage storage where equipment is placed. It is a part.

As shown in FIG. 5, the pillow beam 54 includes an end pillow beam positioned at both ends of the width direction 520 and a central pillow beam positioned in the center of the width direction 520 and through which the exhaust pipe 26 passes. ing. The end pillow beam is composed of a hollow extruded shape that is extruded along the width direction 520. The central pillow beam is constructed by assembling thick plate materials by welding.
The end pillow beam has a plurality of conduits 55 along the longitudinal direction 510 while the air spring 32 is brought into contact with the lower surface thereof. Electric wires and piping intersecting with the pillow beam 54 are laid through the electric conduit 55.

Next, countermeasures for heat of the exhaust pipe 26 will be described. In a portion where the exhaust pipe 26 is located above the main motor 34 of the carriage 30, a heat shield plate 40 is installed on the lower surface of the exhaust pipe 26 to suppress the heat of the exhaust pipe 26 from being transmitted to the main motor 34. (FIG. 5). In addition, although not shown, a heat insulating material is provided at a portion where the exhaust pipe 26 is in contact with the pillow beam 54 in the central portion , and heat from the exhaust pipe 26 is prevented from being transmitted to the pillow beam 54 and the like.

After extending to the end in the longitudinal direction 510 of the railway vehicle through the central part of the railway vehicle, it is laid in such a manner that it rises in the height direction 530 and penetrates the roof structure. That is, the exhaust pipe 26 can secure a large cabin space by being configured not to be laid in the cabin. Further, it is possible to suppress the exhaust pipe 26 provided on the lower surface of the underframe 50 from interfering with the air spring 32. Furthermore, since the exhaust pipe 26 extends up to the end in the longitudinal direction 510 of the railway vehicle, the exhaust pipe 26 stands up inside the deck portion where the passengers get on and off the railway vehicle, or inside the equipment room. The passenger room layout of the railway vehicle equipped with the internal combustion engine 24 and the guest room layout of the railway vehicle not equipped with the internal combustion engine 24 can be shared.

  The two exhaust pipes 26 are arranged in parallel to the horizontal plane on the lower surface of the central portion in the width direction 520 of the underframe 50, and pass through the central pillow beam at the central portion of the pillow beam 54. As a result, it is possible to obtain a wide cabin space in the height direction while suppressing an increase in the height dimension of the central pillow beam.

Further, the outlet of the exhaust pipe 26 is installed on the roof at the end in the longitudinal direction 510 of the railway vehicle, and is located away from the air conditioner 17 installed on the roof at the center in the longitudinal direction 510 . Thereby, it can suppress that the exhaust gas discharged | emitted from the exhaust pipe 26 is taken in into the air conditioner 17, and the air conditioner 17 is soiled.
