Description

Die Erfindung betrifft ein Schienenfahrzeug, insbesondere zur Personenbeförderung, mit einem von Seitenwänden, von einem Wagenkastenboden und von einem Wagendach begrenzten Wagenkasten, der eine Einrichtung zur Be- und Entlüftung des Innenraums des Wagenkastens aufweist.The invention relates to a rail vehicle, in particular for the transport of people, with a car body delimited by side walls, by a car body floor and by a car roof, which has a device for ventilation of the interior of the car body.

Bei Schienenfahrzeugen, insbesondere zur Personenbeförderung, war es allgemein üblich, für den Luftaustausch die konstruktions-, komponenten- und/oder fertigungsabhängigen Undichtigkeiten am Wagenkasten beziehungsweise an dessen Zugangsöffnungen, wie Einstiegstüren oder Faltenbälge an Fahrzeugübergängen, auszunutzen. Dabei wird die über Zulufteinrichtungen zugeführte Luft durch die geöffneten Türen und/oder durch die vorhandenen Ritzen und Spalte infolge unterschiedlichen Luftdruckes nach außen gefördert. Von Nachteil dieser Art des Luftaustausches war die undefinierte Luftführung, welche sich oftmals als Zugluft äußerte und zu Beeinträchtigungen des Fahrkomforts führte. Auch war es nicht zu vermeiden, daß durch die zufälligen Öffnungen Schmutz, Lärm und Feuchtigkeit in das Wageninnere eindringen konnten.In the case of rail vehicles, in particular for the transportation of passengers, it was common practice to use the design, component and / or production-related leaks at the body or at its access openings, such as entrance doors or bellows at vehicle transitions, for air exchange. The air supplied via supply air devices is conveyed to the outside through the open doors and / or through the existing cracks and gaps due to different air pressure. A disadvantage of this type of air exchange was the undefined air routing, which often manifested itself as drafts and led to impaired driving comfort. It was also unavoidable that dirt, noise and moisture could get into the car through the random openings.

Bei Schienenfahrzeugen moderner Bauart, die insbesondere aufgrund der hohen Geschwindigkeiten strömungsgünstig gestaltet sind und weitgehend frei von Leckageöffnungen sind, entfällt diese Möglichkeit des selbsttätigen Luftaustausches. Zur Abhilfe wurden Entlüftungseinrichtungen auf dem Wagendach oder im Seitenwandbereich der Fahrzeuge angeordnet, zum Beispiel sogenannte Kuckuckslüfter. Aber auch diese Art der Entlüftung ist mit Nachteilen behaftet, wie nachfolgend gezeigt wird.This option of automatic air exchange does not apply to modern-design rail vehicles, which are designed to be aerodynamically efficient due to their high speeds and are largely free of leakage openings. To remedy this, ventilation devices were installed on the car roof or in the Side wall area of the vehicles arranged, for example so-called cuckoo fans. However, this type of venting also has disadvantages, as shown below.

Bei Entlüftungen auf dem Wagendach besteht die Gefahr eines strömungsmäßigen beziehungsweise eines thermischen Kurzschlusses, da die Zuluftöffnungen häufig ebenfalls im Dachbereich angeordnet sind. Hierdurch ist der angestrebte Luftaustausch im Fahrzeuginneren nicht mehr gewährleistet, da die zugeführte Frischluft nicht mehr den gesamten Innenraum durchströmt.If there is ventilation on the car roof, there is a risk of a flow or thermal short circuit, since the supply air openings are often also arranged in the roof area. As a result, the desired air exchange inside the vehicle is no longer guaranteed, since the fresh air supplied no longer flows through the entire interior.

Entlüftungsöffnungen, zum Beispiel Schlitze, an der Seitenwand des Fahrzeuges sind sichtbar und stören allein deshalb schon das äußere Erscheinungsbild, wobei dieser Störeffekt durch die erforderlichen Abdeckungen an der Fahrzeugaußenseite noch verstärkt wird. Außerdem ist auch hierbei eine definierte Luftführung von der Decke zum Fußboden nicht gewährleistet.Vent openings, for example slits, on the side wall of the vehicle are visible and for this reason alone disturb the external appearance, this interference effect being intensified by the necessary covers on the outside of the vehicle. In addition, a defined air flow from the ceiling to the floor is not guaranteed.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, für ein Schienenfahrzeug der eingangs genannten Art eine Einrichtung zur Be- und Entlüftung des Innenraums des Wagenkastens anzugeben, welche einfach gestaltet und ohne großen Aufwand herstellbar ist und welche einen wirkungsvollen Luftaustausch gewährleistet unter Vermeidung jeglicher Beeinträchtigung durch Zugluft oder unerwünschtes Eindringen von Feuchtigkeit, Schmutz oder Geräuschen.Based on this prior art, it is an object of the invention to provide a device for ventilation of the interior of the car body for a rail vehicle of the type mentioned, which is simple in design and can be produced without great effort and which ensures effective air exchange while avoiding any Impaired by drafts or unwanted penetration of moisture, dirt or noise.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind in den Unteransprüchen dargelegt und gekennzeichnet.This object is achieved according to the invention by the characterizing features of patent claim 1. Further advantageous refinements and improvements of the invention are set out and characterized in the subclaims.

Entsprechend der Erfindung ist vorgesehen, daß die Einrichtung zur Be- und Entlüftung des Innenraums des Wagenkastens von einer am Wagendach angeordneten Zulufteinrichtung und von wenigstens einer in den Wagenkastenboden eingelassenen Abluftöffnung gebildet ist. Dabei ist festzuhalten, daß auf dem Dach angeordnete Zulufteinrichtungen an sich in vielfacher Form bereits bekannt sind, zum Beispiel in Form von planmäßig oder nachträglich auf dem Wagendach installierten Klimaanlagen, welche klimatisierte Frischluft in das Fahrzeuginnere zuführen. Hingegen wurde jedoch von einer Anordnung von Abluftöffnungen im Fußbodenbereich abgesehen, da bei ungünstiger Gestaltung eine ungünstige Temperaturverteilung, das Auftreten von Zugluft sowie eine Belästigung durch einen hohen Geräuschpegel nicht auszuschließen ist.According to the invention it is provided that the device for ventilation of the interior of the car body is formed by an air supply device arranged on the car roof and by at least one exhaust air opening let into the car body floor. It should be noted that supply air devices arranged on the roof are already known in a variety of ways, for example in the form of air conditioning systems installed on the roof of the car according to plan or subsequently, which supply fresh air-conditioned air into the vehicle interior. On the other hand, however, an arrangement of exhaust air openings in the floor area was dispensed with, since with an unfavorable design an unfavorable temperature distribution, the occurrence of drafts and annoyance from a high noise level cannot be excluded.

In vorteilhafter Weiterbildung der Erfindung kann vorgesehen sein, daß die Abluftöffnung von einer luftdurchlässigen Abdeckung abgedeckt ist und mit einem am Wagenkastenbodens angeordneten Luftkanal verbunden ist. Hierbei bildet der Luftkanal im Vergleich zu einer unmittelbar mit der Außenluft kommunizierenden Abluftöffnung gleichsam eine Barriere für eine unmittelbare Beaufschlagung des Fahrzeuginnnenraums durch Fahrgeräusche, Feuchtigkeit und Verschmutzung, da diese zunächst den Luftkanal durchströmen müssen, bevor sie in das Wageninnere gelangen können.In an advantageous development of the invention it can be provided that the exhaust air opening is covered by an air-permeable cover and is connected to an air duct arranged on the floor of the vehicle body. In comparison to an exhaust air opening that communicates directly with the outside air, the air duct forms a barrier for direct exposure to the vehicle interior through driving noise, moisture and dirt, since these must first flow through the air duct before they can get into the vehicle interior.

Der erwähnte Luftkanal kann dabei in die Gestaltung des Fahrzeugbodens integriert sein oder aber vorteilhafterweise unterhalb des Wagenkastenbodens angeordnet und von einem an den Wagenkastenboden angeformten Kragen gebildet sein, welcher über eine seitliche Öffnung mit der Außenluft in Verbindung steht.The air duct mentioned can be integrated into the design of the vehicle floor or advantageously arranged below the vehicle body floor and formed by a collar molded onto the vehicle body floor, which is connected to the outside air via a side opening.

Diese Gestaltung bietet den Vorteil einfacher Herstellbarkeit, da der Luftkanal aus Flachmaterial, insbesondere aus Blech beziehungsweise gegebenenfalls aus Kunststofftafeln, geformt werden kann. Die Gestaltung mit einem Kragen gewährleistet einen gleichmäßigen Luftaustritt, wobei entsprechend der konstruktiven Gestaltung des Kragens dieser als Schikane für eine rückwärts, das heißt in das Wageninnere, gerichtete Strömung wirkt.This design offers the advantage of being easy to produce, since the air duct can be formed from flat material, in particular from sheet metal or, if appropriate, from plastic sheets. The design with a collar ensures a uniform air outlet, which, in accordance with the structural design of the collar, acts as a chicane for a flow directed backwards, that is to say into the interior of the car.

Entsprechend einer bevorzugten Ausführungsform erstreckt sich die seitliche Öffnung im Luftkanal über dessen Länge und ist spaltartig ausgebildet. Der Längsspalt ist dabei zur Wagenlängsmitte hin geöffnet, um das Eindringen der Abrollgeräusche der Räder des Schienenfahrzeugs zu erschweren.According to a preferred embodiment, the lateral opening in the air duct extends over its length and is designed in the form of a gap. The longitudinal gap is open towards the middle of the carriage to make it more difficult for the rolling noise of the wheels of the rail vehicle to penetrate.

Abhängig von der Größe des Austauschluftstroms ist nur eine Abluftöffnung zur Entlüftung des Innenraums des Wagenkastens vorgesehen, die jeweils unterhalb eines Fahrgastsitzes beziehungsweise durch andere Überbauten geschützt angeordnet ist. Doch können auch mehrere Abluftöffnungen vorgesehen sein, die jeweils unterhalb eines Fahrgastsitzes angeordnet sind.
In vorteilhafter Ausgestaltung der Erfindung ist jede Abluftöffnung jeweils randnah an der Längsaußenseite angeordnet. Die Größe der Abluftöffnung ist hierbei entsprechend dem erforderlichen Ausströmquerschnitt festgelegt, wobei ein Rechteck mit einer Größe von etwa 600 cm2 (entsprechend 200 mm * 300 mm) je Abluftöffnung bei insgesamt vier Abluftöffnungen je Wagenkasten als ausreichend anzusehen ist. Hierdurch wird eine ausreichende, weitgehend gleichmäßige Luftabfuhr erreicht und eine gute Luftzirkulation sichergestellt.Depending on the size of the exchange air flow, only one exhaust air opening is provided for venting the interior of the car body, which is arranged in a protected manner below a passenger seat or by other superstructures. However, several exhaust air openings can also be provided, each of which is arranged below a passenger seat.
In an advantageous embodiment of the invention, each exhaust air opening is arranged close to the edge on the longitudinal outside. The size of the exhaust air opening is corresponding the required outflow cross-section, whereby a rectangle with a size of approximately 600 cm 2 (corresponding to 200 mm * 300 mm) per exhaust air opening with a total of four exhaust air openings per car body is to be regarded as sufficient. This achieves sufficient, largely uniform air removal and ensures good air circulation.

Um das störende Zuströmen von Fremdluft sowie das Eindringen von Feuchtigkeit zu verhindern, sind zumindest unterhalb einer jeden Abluftöffnung im Luftkanal Luftleitbleche angeordnet sind. Dabei kann vorgesehen sein, daß die Luftleitbleche sich überlappen und schräg angestellt sind und so das Eindringen von Feuchtigkeit und Fremdkörpern durch die Abluftöffnung in das Innere des Wagenkastens verhindern.In order to prevent the disturbing inflow of external air and the penetration of moisture, air baffles are arranged at least below each exhaust air opening in the air duct. It can be provided that the air baffles overlap and are inclined and thus prevent the ingress of moisture and foreign bodies through the exhaust opening into the interior of the car body.

Zur Vermeidung des Eindringens von Geräuschen in das Wagenkasteninnere kann entsprechend einer vorteilhaften Ausführungsform der Erfindung vorgesehen sein, , daß der Luftkanal zumindest im Bereich der spaltartigen Öffnung mit schalldämpfendem Material ausgekleidet ist, welches Störgeräusche unterdrückt.In order to avoid the penetration of noise into the interior of the car body, it can be provided according to an advantageous embodiment of the invention that the air duct is lined, at least in the area of the gap-like opening, with sound-absorbing material which suppresses noise.

Ebenso ist gemäß einer weiteren Ausgestaltung der Erfindung die Abluftöffnung am Fahrzeugboden mit einer Abdeckung, vorzugsweise ein Gitter, zum Beispiel aus Streckmetall, oder ein Lochblech, versehen.Likewise, according to a further embodiment of the invention, the exhaust air opening on the vehicle floor is provided with a cover, preferably a grid, for example made of expanded metal, or a perforated plate.

Um die Stolpergefahr zu verringern und die Bodenreinigung zu begünstigen, ist vorteilhafterweise vorgesehen, daß die Abdeckung jeder Abluftöffnung jeweils bündig mit dem Wagenkastenboden abschließt. Fall der Wagenkastenboden mit einem Bodenbelag versehen ist, schließt die Abdeckung mit diesem bündig ab.In order to reduce the risk of stumbling and to favor floor cleaning, it is advantageously provided that the cover of each exhaust opening is flush with the floor of the car body. If the car body floor is provided with a floor covering, the cover is flush with this.

Im Hinblick auf eine einfach durchzuführende Reinigung des Luftkanals oder eines einfachen Austausches bei Beschädigung ist der Luftkanal abnehmbar am Wagenkasten angebracht.With a view to easy cleaning of the air duct or a simple exchange in the event of damage, the air duct is detachably attached to the car body.

Generell ist hervorzuheben, daß die erfindungsgemäße Einrichtung zur Be- und Entlüftung nicht nur bei klimatisierten Fahrzeugen, das heißt bei Fahrzeugen, bei denen eine Kühleinrichtung zur Kühlung der Luft für den Fahrgastraum vorgesehen ist, von Vorteil ist, sondern auch bei einer herkömmlichen Heizlüftungsanlage. Bei Fahrzeugen, die mit einer derartigen Anlage ausgestattet sind, besteht nämlich ein Luftdurchsatz, der bis zu dreimal höher als bei vollklimatisierten Fahrzeugen der Fall ist.In general, it should be emphasized that the ventilation device according to the invention is advantageous not only in air-conditioned vehicles, that is to say in vehicles in which a cooling device is provided for cooling the air for the passenger compartment, but also in a conventional heating ventilation system. In vehicles that are equipped with such a system, there is a Air flow that is up to three times higher than that of fully air-conditioned vehicles.

Ferner wird mit der erfindungsgemäßen Einrichtung der Überdruck im Wageninneren vermieden, der bei der immer besseren Abdichtung der modernen Schienenfahrzeuge zu Problemen führen kann, zum Beispiel erschwertes selbsttätiges Öffnen der Fahrzeugtüren. Ein solcher Überdruck kann sich insbesondere bei Heiz- und Klimaanlagen mit Lüfterbetrieb aufbauen.Furthermore, the device according to the invention avoids the excess pressure in the interior of the car, which can lead to problems with the ever better sealing of modern rail vehicles, for example difficult automatic opening of the vehicle doors. Such overpressure can build up especially in heating and air conditioning systems with fan operation.

Diese und weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind Gegenstand der Unteransprüche.These and further advantageous refinements and improvements of the invention are the subject of the dependent claims.

Anhand eines in der schematischen Zeichnung dargestellten Ausführungsbeispiels sollen die Erfindung, vorteilhafte Ausgestaltungen und Verbesserungen sowie besondere Vorteile der Erfindung näher erläutert und beschrieben werden.The invention, advantageous refinements and improvements and special advantages of the invention are to be explained and described in more detail with reference to an embodiment shown in the schematic drawing.

Im Innenraum 11 des Wagenkastens 10 sind Sitzplätze 18 für Fahrgäste angeordnet.1 shows a cross section through a car body 10 of a rail vehicle (not shown) for passenger transport, which is bounded by side walls 12, 13, by a car body floor 14 and by a roof 16. Seats 18 for passengers are arranged in the interior 11 of the car body 10.

Auf dem Dach 16 ist eine als Klimatisierungsanlage ausgebildete und zu einer Einrichtung 20 für die Be- und Entlüftung des Wagenkastens 10 gehörige Zulufteinrichtung 22 angeordnet, welche über zwei Zuluftöffnungen 24 im Dach 16 mit dem Innenraum 11 in Verbindung steht und durch diese den Innenraum bedarfsweise mit erwärmter oder gekühlter Frischluft versorgt. Mittels je zweier eingezeichneter Pfeile 26, die jeweils einer der beiden Zuluftöffnungen 24 zugeordnet sind, ist der Strömungsweg für die Frischluft dargestellt. Diese Darstellung zeigt, daß die zugeführte Frischluft den Querschnitt des Innenraums 11 durchströmt und unterhalb der Sitzplätze 18 durch dort angeordnete Abluftöffnungen 28 abströmt.On the roof 16, a supply air device 22, which is designed as an air conditioning system and is part of a device 20 for ventilation of the car body 10, is arranged, which has two supply air openings 24 in the roof 16 with the interior 11 is connected and supplies the interior with heated or cooled fresh air as needed. The flow path for the fresh air is shown by means of two arrows 26 drawn in, each of which is assigned to one of the two supply air openings 24. This illustration shows that the fresh air supplied flows through the cross section of the interior 11 and flows out below the seats 18 through exhaust air openings 28 arranged there.

Die erfindungsgemäß vorgesehenen Abluftlöffnungen 28 sind von in den Wagenkastenboden eingelassenen Ausnehmungen gebildet, die randnah entlang der Längsaußenseite, wie insbesondere aus der in Fig. 2 gezeigten Schrägansicht des aufgeschnittenen Wagenkastens 10 zu erkennen ist, in Längsrichtung zueinander versetzt angeordnet sind.The exhaust air openings 28 provided according to the invention are formed by recesses recessed into the floor of the car body, which are arranged offset along the longitudinal side near the edge, as can be seen in particular from the oblique view of the cut open car body 10 shown in FIG. 2, in the longitudinal direction.

Bei dem in der schematischen Darstellung gemäß Fig. 2 gezeigten, teilweise aufgeschnittenen Wagenkasten 10 ohne Fenster, Türen beziehungsweise Einstiegsbereiche ist die Zulufteinrichtung 22 etwa in Wagenkastenmitte angeordnet und erstreckt sich hierbei über die gesamte Breite des Wagenkastens 10. Über eine Eintrittsöffnung 23 wird Umgebungsluft in die Zulufteinrichtung 22 eingesaugt, darin aufbereitet, das heißt mittels Filter gereinigt, erwärmt oder gekühlt und dann in den Innenraum 11 gefördert. Dort verläßt die zugeführte Luft den Innenraum nach dessen Durchströmen durch die am Wagenkastenboden 12 vorgesehenen Abluftöffnungen 28, die ihrerseits mit einem in Fig. 1 und deutlicher in Fig. 3 gezeigten Luftkanal 30 verbunden ist.In the partially cut open car body 10 shown in the schematic representation according to FIG. 2 without windows, doors or entry areas, the supply air device 22 is arranged approximately in the middle of the car body and extends over the entire width of the car body 10. Ambient air is introduced into the through an inlet opening 23 Supply air device 22 is sucked in, processed therein, that is, cleaned, heated or cooled by means of a filter and then conveyed into the interior 11. There, the supplied air leaves the interior after flowing through the exhaust air openings 28 provided on the vehicle body floor 12, which in turn is connected to an air duct 30 shown in FIG. 1 and more clearly in FIG. 3.

Der Luftkanal 30 ist kragenartig ausgebildet und aus Blech oder gegebenenfalls aus Kunststoffplatten gefertigt. Er begrenzt einen Raum 32 mit rechteckförmigem Querschnitt, in welchem erste und zweite Luftleitbleche 34, 35 angeordnet sind und an den sich ein spaltartiger Raum 36 anschließt, der mit einer schalldämmenden Schicht 37 versehen und zur Wagenlängsmitte hin offen ist, so daß die über die Abluftöffnungen 28 zugeströmte verbrauchte Luft an die Umgebung abströmen kann.The air duct 30 is collar-shaped and made of sheet metal or, if appropriate, of plastic plates. It delimits a space 32 with a rectangular cross-section, in which first and second air baffles 34, 35 are arranged and to which a gap-like space 36 adjoins, which is provided with a sound-absorbing layer 37 and is open towards the middle of the carriage, so that it extends over the exhaust air openings 28 inflow of used air can flow to the environment.

Die Abluftöffnungen 28 sind, wie in Fig. 3 gezeigt jeweils mit einer luftdurchlässigen, zum Beispiel als Gitter oder als Lochblech ausgebildeten Abdeckung 38 versehen, die bündig mit dem Wagenkastenboden 14 beziehungsweise mit einem darauf angeordneten Bodenbelag 15 abschließt. sehen, die bündig mit dem Wagenkastenboden 14 beziehungsweise mit einem darauf angeordneten Bodenbelag 15 abschließt.As shown in FIG. 3, the exhaust air openings 28 are each provided with an air-permeable cover 38, for example in the form of a grille or a perforated plate, which ends flush with the car body floor 14 or with a floor covering 15 arranged thereon. see that ends flush with the car body floor 14 or with a floor covering 15 arranged thereon.
