この考案は、動力機関の排気を車両の屋根から
排出させるように構成した鉄道車両の排気装置に
関し、特に車両の頭部をほゞ垂直な面で構成した
鉄道用デイーゼル動車に適用して最適なものであ
る。[Detailed description of the invention] [Industrial field of application] This invention relates to an exhaust system for a railway vehicle configured to discharge exhaust gas from a power engine through the roof of the vehicle. It is most suitable for application to diesel railway vehicles configured with a flat surface.
この考案は、排気を屋根から排出させるように

ものである。
This invention is an exhaust system for a railway vehicle configured to discharge exhaust gas from the roof, by arranging a variable current plate above the end of the roof near the head of the vehicle to form a wind path. This system regulates the flow of exhaust gas and prevents it from flowing into the passenger compartment.
鉄道車両の頭部１に、車両走行中、第４図に示
すごとく衝突する空気は、頭部１の面にほゞ沿つ

乱流などを生じる。
Air that collides with the head 1 of a railway vehicle while the vehicle is running, as shown in FIG. 4, flows approximately along the surface of the head 1 and then flows away rearward along the vehicle 2. However, this flow of air is likely to cause phenomena such as separation from the vehicle 2 depending on the outer shape of the vehicle 2 and the condition of the outer surface of the vehicle 2, and turbulence is generated everywhere.
特に車両２の頭部１が、第４図に示すごとく垂
直な面で構成された場合（以下「切妻型」と略
す）は、頭部１と屋根３とは図示のように直交す
るから、空気は屋根端部３ａで車両２から剥離
し、この屋根端部３ａには空気の負圧部分を生じ
る。 In particular, when the head 1 of the vehicle 2 is configured with a vertical surface as shown in FIG. 4 (hereinafter abbreviated as "gable type"), the head 1 and the roof 3 are perpendicular to each other as shown in the figure. The air separates from the vehicle 2 at the roof end 3a, creating a negative air pressure section at the roof end 3a.
このため屋根３に配設された排気管４から排出
する排気５は、図示の矢印のごとく上記負圧部分
に向つて流れ込み、その後乱れた空気の流れに載
つて図示の矢印に示すごとくたとえば車窓１０か
らその一部が社内に流入し、車内を汚染する。 For this reason, the exhaust gas 5 discharged from the exhaust pipe 4 disposed on the roof 3 flows toward the negative pressure area as shown by the arrow in the figure, and then rides on the turbulent air flow and flows toward the car window, for example, as shown by the arrow in the figure. From 10 onwards, some of it flows into the company and contaminates the inside of the car.
そこでこのような課題を解決するために、たと

したものである。かくして排気５は、車両２の屋
根３沿いに流れることがなくなるから、排気５が
屋根３に設けた空気取入口９より車内に流入する
事態は避けることができる。 In order to solve this problem, for example, Japanese Patent Laid-Open No. 128957/1983 discloses an "exhaust blow-up device" as shown in FIG. 5A. That is, in this device, as shown by the solid line arrow in FIG.
, the upper end 4a of the exhaust pipe 4 as shown in FIG. 5B.
The exhaust 5 is caused by the upward flow of the air.
The flow is made to flow upward as indicated by the dotted arrow shown in the figure. In this way, the exhaust gas 5 does not flow along the roof 3 of the vehicle 2, so that a situation where the exhaust gas 5 flows into the vehicle through the air intake port 9 provided in the roof 3 can be avoided.
しかしながら頭部１が、たとえば第４図に示す
ごとく切妻型であり、さらに排気管４も、同図に

明らかになつている。
However, if the head 1 is of a gable type, as shown in FIG. 4, and the exhaust pipe 4 is also provided close to the roof end 3a, as shown in FIG. 8 as shown by the solid line arrow in FIG. Wind tunnel experiments conducted by the applicant have also revealed that the liquid flows into pressure areas.
したがつて排気管４から第５Ｂ図に示すように
排出される排気５も、上記逆向きに流れる空気に
伴われて上記負圧部分に流れ込み、既に第４図に
示したように、その一部が車内に流入するおそれ
がある。 Therefore, the exhaust gas 5 discharged from the exhaust pipe 4 as shown in FIG. 5B also flows into the negative pressure section along with the air flowing in the opposite direction, and as already shown in FIG. There is a risk that the liquid may flow into the vehicle.

転手段が特に必要となる。 Furthermore, the exhaust induction box 8 shown in FIG. 5A has a complicated structure and requires time and effort to manufacture. Furthermore, it is not easy to attach the box 8 to the upper end 4a of the exhaust pipe 4. Furthermore, if the structurally unbalanced exhaust guide box 8 is attached to the exhaust pipe 4 and placed in a strong air flow, harmful vibrations are likely to be induced and the exhaust guide box 8 and the exhaust pipe may be damaged. Therefore, if an attempt is made to attach the exhaust guide box 8 not only to the exhaust pipe 4 but also to the roof 3 to ensure its installation, it becomes increasingly difficult to rotate the exhaust guide box 8 with respect to the exhaust pipe 4, and the exhaust guide box 8 becomes difficult to rotate relative to the exhaust pipe 4. It becomes almost impossible to change the direction of the signal 8 to match the direction of travel of the vehicle 2, or
Alternatively, a complicated rotation means is particularly required to rotate the exhaust induction box 8.
本考案は上述の点に鑑み、簡単な構造であるに
も拘らず、車内への排気の流入を防止できる鉄道
車両の排気装置を提供するものである。 In view of the above-mentioned points, the present invention provides an exhaust system for a railway vehicle that can prevent exhaust gas from flowing into the interior of the vehicle despite having a simple structure.

The device according to the invention is therefore very simple in its construction. Moreover, since it is only necessary to attach it to the roof rather than to the exhaust pipe, the installation work is extremely easy and can be done reliably. Furthermore, since the length of the mounting portion can be easily extended to the desired length and the mounting is as secure as described above, it is extremely simple to ensure that the device is free from harmful vibrations. Furthermore, since the device of the present invention can be simply and easily installed at the front and rear ends of the vehicle as required, the device can always be operated effectively even if the direction of travel of the vehicle changes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a railway diesel vehicle having a substantially gable-shaped vehicle head will be described below with reference to FIGS. 1 to 3. In the following description, the same reference numerals are given to the parts having substantially the same structure as those shown in FIGS. 4 to 5B, and the description thereof will be omitted.
第１図および第２図に示すように、上記鉄道用
デイーゼル動車の頭部１は切妻型でまた屋根３は
蒲鉾形に形成されている。なお符号１０および１
１はそれぞれ車窓および走り装置である。 As shown in FIGS. 1 and 2, the head 1 of the railway diesel vehicle is gable-shaped and the roof 3 is semi-cylindrical. Note that the codes 10 and 1
1 is a car window and a running device, respectively.
上記頭部１と屋根３とは第１図に示すごとく直

および脚板１５によつて、断面がほゞ矩形状をし
た風道１７が屋根端部３ａに形成される。 By the way, on the roof end 3a near the head 1, there is a current transformation plate 1 above it and almost along the roof 3.
2 is provided. This variable current plate 12 is fixed to the roof via a pair of leg plates 15 protruding from its left and right ends. This fixation is by bolts 16, but could also be by welding or riveting. Thus, as shown in FIG.
A wind passage 17 having a substantially rectangular cross section is formed at the roof end 3a by the leg plates 15.

あるいは車両２の走行速度などを勘案して適切に
決められる（たとえば出願人は風洞実験を行つ

めた）。 The length, width, height, etc. of this air passage 17 mainly depend on the position and height of the exhaust pipe 4, the amount of exhaust gas 5,
Alternatively, it can be appropriately determined in consideration of the traveling speed of the vehicle 2, etc. (for example, the applicant conducted wind tunnel experiments to determine appropriate values for the various quantities mentioned above in the case of the embodiment).

また場合によれば、端部１２ａを上記頭部端より
も突出させないように構成することもできる。 Further, the end portion 12a of the current variable plate 12 is made to protrude from the head 1 of the vehicle 2 which has a vertical surface shape as shown in FIG. The portion 12a may be provided so that the head 1 projects beyond the end of the head where the head 1 connects to the roof 3.
Further, depending on the case, the end portion 12a may be configured not to protrude beyond the head end.

の高さなどを勘案して適切に決められる。 Next, between the current transformation plate 12 and the exhaust pipe 4, and in the vicinity of the exhaust pipe 4, there is a trapezoidal projection 18 for current transformation.
is protruding from the roof 3. The width of this protrusion 18 is approximately equal to the width of the air passage 17, as shown in FIG.
Note that the length and height of the protrusion 18 or the protrusion 1
The angle, shape, etc. of the slope 18a provided at the 8 ends are determined depending on the distance between the protrusion 18 and the air passage 17, and the exhaust pipe 4.
It can be determined appropriately by taking into account the height of the

きに、たとえば以下のごとくなるように選定され
る。 That is, the above-mentioned conditions regarding the mutual relationship between the current plate 12 and the current transformation protrusion 18 are selected such that when air collides with the traveling vehicle and then flows away along the vehicle 2, the conditions are as follows, for example. .
たとえば第１図で車両２が左方に進行すると、

１２によつて風道１７内に誘導され、かつ風道１
７内にて整流される。次に風道１７から流出した
上記空気は、突起１８によつて図示のように流れ
の向きを上向きに変えられる。 For example, when vehicle 2 moves to the left in Figure 1,
As shown by the solid arrow in FIG. 1, the air in front of the vehicle 2 first collides with the head 1 of the vehicle 2, and then flows in all directions almost along the surface of the head 1. Among these airflows, the upward airflow is guided into the airway 17 by the current changing plate 12 as shown in the figure, and
It is rectified within 7. Next, the flow direction of the air flowing out from the air passage 17 is changed upward by the protrusion 18 as shown in the figure.

て排気５が車内に流れ込むようなおそれはない。 The exhaust gas 5 thus discharged from the exhaust pipe 4 flows in the direction of the arrow shown by the dotted line in the figure along with the upwardly flowing air flow (shown by the solid line). Even if the exhaust gas 5 is provided on the roof 3 of the vehicle 2, there is no fear that the exhaust gas 5 will flow into the interior of the vehicle through the air intake port 9.
なお屋根３に上記の空気取入口９を設けない車

つてこのような場合には、変流用突起１８が不要
になる。 Note that if we consider a vehicle that does not have the above-mentioned air intake port 9 on the roof 3, the air will flow away along the roof 3 due to the rectifying effect of the wind duct 17, so even if the protrusion 18
Even if it is not provided, there is no risk that the exhaust gas 5 will flow into the vehicle through the window 10 provided on the side of the vehicle 2. Therefore, in such a case, the current transformation protrusion 18 becomes unnecessary.
