TECHNICAL FIELD OF THE INVENTION
The present invention relates to a railway vehicle having an improved wind path.
[0002]
[Prior art]
A conventional airway structure in the railway vehicle 10 will be described with reference to the right half view of FIG. The same parts as those of the embodiment of the invention described later are designated by the same reference numerals, detailed description will be omitted, and only the main points will be described. The duct 20 is fixed to the inner surface of the ceiling of the structure 12, extends in the front-rear direction of the railway vehicle 10, and forms an air passage 22 inside. The duct 28 is fixed to a corner of the floor 26, extends in the front-rear direction of the railway vehicle 10, and forms an air passage 30 inside.
[0003]
[Problems to be solved by the invention]
In the conventional airway structure, since the ducts 20 and 28 are used to form the airways 22 and 30, the ducts 20 and 28 protrude greatly from the inner surface of the ceiling portion or the inner surface of the lower corner of the structure 12 toward the room. As a result, the interior space becomes narrower, leading to an increase in vehicle weight and an increase in manufacturing cost.
[0004]
An object of the present invention is to provide a railway vehicle capable of suppressing a reduction in indoor space due to a wind path, reducing the weight and streamlining production.
[0005]
[Means for Solving the Problems]
A railway vehicle (10) of the present invention includes an airway (24) in a structure (12).
[0006]
In the railcar (10), the airway (24) is formed in the structure (12), so that a decrease in the indoor space can be suppressed. Further, since a member dedicated to forming the wind path (24) can be omitted or reduced, the vehicle can be reduced in weight and production can be rationalized.
[0007]
In another railway vehicle (10) of the present invention, the wind path (24) is a hollow space in a hollow mold member or a hollow space formed by joining a plurality of mold members.
[0008]
In this railway vehicle (10), since the hollow space of the hollow mold members or the mutually joined mold members is the air passage (24), the manufacture of the air passage (24) in the structure (12) can be simplified. .
[0009]
In another railway vehicle (10) of the present invention, the hollow member or the member is an extruded member made of an aluminum alloy.
[0010]
The formation of the air passage (24) by the hollow space by the aluminum alloy extruded die material can further reduce the weight and rationalize the production.
[0011]
In another railway vehicle (10) of the present invention, the roof girder (40) is made of a hollow material or a shape material, and the wind path (24) is for fresh air.
[0012]
In this railway vehicle (10), fresh air flows through the roof girder (40) at the ceiling. Although the airway (24) has insufficient heat insulation with the outside air due to its position, the airway (24) can perform its function without trouble by using it for fresh air.
[0013]
In another railway vehicle (10) of the present invention, the airway (24) has an airflow amount adjusting means (60) for adjusting the airflow in the airway (24) by increasing or decreasing the flow cross-sectional area of the airway (24). ) Is arranged.
[0014]
In this railway vehicle (10), the airflow adjusting means (60) in the airway increases or decreases the flow cross-sectional area of the air in the airway (24) by changing the rotation angle or the like. The air volume changes. Thus, the air volume in the air path (24) can be appropriately adjusted.
[0015]
In another railway vehicle (10) according to the present invention, the amount of diverting fresh air flowing in the wind path (24) toward the fresh air inlet (56) of the indoor air conditioner (52) is adjusted by increasing or decreasing the rotation angle. A deflecting member (64) is disposed in the wind path (24).
[0016]
In the railway vehicle (10), the deflecting member (64) changes the amount of deflecting of fresh air from the wind path (24) to the fresh air suction port (56) by changing the rotation angle, and the deflecting member (64). And the amount of fresh air flowing toward the wind path (24) downstream of the deflecting member (64) is changed. In this way, the amount of fresh air taken into the indoor air conditioner (52) from the air path (24) and the amount of air in the air path (24) can be adjusted to appropriate values.
[0017]
In another railway vehicle (10) of the present invention, the wind path forming member (32) extends along the inner surface of the structure (12) along the inner surface, and the wind outside the structure is provided between the structure and the inner surface of the structure (12). A road (34) is formed, and an in-structure airway (36) is formed in the structure (12) adjacent to the off-structure airway (34) in communication with the off-structure airway (34).
[0018]
In this railway vehicle (10), the wind flows through the in-structure wind path (36) and the off-structure wind path (34) that are in communication with each other, so that the off-structure wind path (34). Can be made as small as possible, and a decrease in the indoor space due to the wind path can be suppressed. Furthermore, since the members dedicated to the airway can be reduced, the weight of the vehicle can be reduced and the production can be rationalized.
[0019]
In another railcar (10) of the present invention, the in-building airway (36) and the off-structure airway (34) are for exhaust, and the in-building airway (36) is a side beam (66) and / or a long beam. It is formed in a base (68).
[0020]
In this railway vehicle (10), the exhaust flows through the air duct (36) in the premises in the side beams (66) and / or the long base (68). Although the internal airway (36) has insufficient heat insulation with the outside air due to its position, the airway (36) can perform its function without trouble by use for exhaust.
[0021]

Further, the in-structure exhaust airway 36 extends in the structure 12 adjacent to the out-of-structure exhaust airway 34, and communicates with the out-of-structure exhaust airway 34 in the front-rear direction of the railway vehicle 10 as appropriate. In the prior art, the entire amount of wind flows through the duct 28, whereas in the embodiment of the present invention, the wind mainly flows through the air exhaust path 36 in the internal structure 12 and An amount of wind that is not sufficient by the path 36 alone flows through the off-structure exhaust path 34. Therefore, it is possible to reduce the cross-sectional area of the out-of-compartment exhaust airway 34 and to increase the space at the lower corner of the room.
[0024]
FIG. 1 is a detailed structural view of the fresh air passage 24 formed in the roof girder 40 of the structure 12. The roof girder 40 constitutes the structure 12 together with the structure main body 38, and is made of one aluminum alloy hollow stamp or a plurality of aluminum alloy stamps joined to each other. The heat insulating material 42 covers the indoor surface of the roof girder 40 while being loaded on the indoor side of the structural body 38. The outer surface and the inner surface of the upper wall of the roof girder 40 are covered with heat insulating materials 44 and 46, respectively. The fresh air passage 24 is formed as a hollow space of the roof girder 40, and is insulated to the outside by heat insulating materials 42, 44, 46.

[0026]
When the amount of fresh air to be taken into the fresh air suction port 56 is changed, the lower end of the shaft 62 of the air volume adjusting means 60 which projects downward from the lower surface of the roof girder 40 and is exposed is turned from the indoor side. Thereby, the rotational position of the blade 64 of the air volume adjusting means 60 changes. Since the effective collision cross-sectional area where fresh air flowing in the fresh air flow path collides with the blade 64 changes according to the rotational position of the blade 64, the rotational position of the blade 64 changes and collides with the blade 64, and The air is diverted toward the fresh air suction port 56, and the amount of fresh air introduced into the fresh air suction port 56 changes. The air volume adjusting means 60 on the left and right sides in FIG. 2 direct the blades 64 in the front-rear direction and the left-right direction of the railway vehicle 10, respectively, and serve as the intake positions of the minimum and maximum airflow of the fresh air into the fresh air inlet 56. ing. The fresh air that has not been taken into the fresh air suction port 56 by the blades 64 passes through the air volume adjusting unit 60 and proceeds to the fresh air passage downstream of the air volume adjusting unit 60, and the air volume adjusting unit 60 Has a function of adjusting the flow rate of fresh air in the fresh air passage by increasing or decreasing the flow cross-sectional area of the fresh air passage. A plurality of indoor air conditioners 52 are arranged in the front-rear direction of the railway vehicle 10, and each communicate with a different portion of the fresh air passage through a fresh air inlet 56. By adjusting the air volume adjusting means 60 corresponding to each indoor air conditioner 52, the amount of fresh air taken into the indoor air conditioner 52 via the fresh air suction port 56 and the amount of fresh air on the downstream side thereof are adjusted. By adjusting the flow rate of the fresh air toward the fresh air, it is possible to harmonize the intake amounts of the indoor air conditioners 52 into the fresh air suction port 56 as a whole.
[0027]
Although the fresh air passage 24 is located at a position where the heat insulation from the outside air is insufficient, the fresh air passage 24 exhibits its function without any particular problem in heat insulation by being used for fresh air.
