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 transportation of people, with one of side walls, one body floor and one Car roof limited car body, which is 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.It was general for rail vehicles, especially for passenger transportation usual, for the air exchange the design, component and / or production-dependent Leaks in the car body or in its Access openings, such as entrance doors or bellows at vehicle crossings, exploit. The air supplied via supply air devices is thereby through the opened doors and / or through the existing cracks and gaps as a result of different Air pressure conveyed to the outside. A disadvantage of this type of air exchange was the undefined air flow, which was often expressed as drafts and impaired driving comfort. Nor was it closed Avoid getting dirt, noise and moisture in through the random openings that could get inside the car.

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 Kukkuckslüfter. Aber auch diese Art der Entlüftung ist mit Nachteilen behaftet, wie nachfolgend gezeigt wird.Rail vehicles of modern design, which are particularly due to the high Speeds are streamlined and largely free of If there are leakage openings, this option of automatic air exchange is eliminated. 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. But this type of ventilation also has disadvantages, such as is 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 a thermal short circuit, as the supply air openings are frequent are also arranged in the roof area. This is the desired air exchange inside the vehicle is no longer guaranteed because 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.Vents, for example slots, on the side wall of the vehicle are visible and therefore disturb the external appearance alone, whereby this disruptive effect due to the required covers on the outside of the vehicle is reinforced. In addition, there is also a defined air flow from the ceiling to the floor is not guaranteed.

Aus der DE-A-41 23 584 ist ein Autoreisezug mit Transportwagen für Kraftfahrzeuge und Personenwagen bekannt, bei dem ein gleichzeitig als Regen- und Schnee-Schmelzwasseraustritt dienender Luftaustritt vom Ladeboden des Transportwagens nach außen führt. Ein Eindringen von Feuchtigkeit, Schmutz oder Geräuschen durch den Luftaustritt in den Innenraum des Transportwagens kann aufgrund des verhältnismäßig großen Durchtrittsquerschnitt des Luftaustritts nicht zuverlässig verhindert werden.From DE-A-41 23 584 is a car train with a trolley for motor vehicles and passenger cars are known, in which a simultaneously as rain and snow melt water outlet serving air outlet from the loading floor of the transport vehicle leads outside. Penetration of moisture, dirt or noise through the Air leakage into the interior of the trolley can be proportionate large cross-section of the air outlet cannot be reliably prevented.

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 for a Rail vehicle of the type mentioned a device for ventilation the interior of the car body, which is simple and can be produced with little effort and which is an effective air exchange guaranteed while avoiding any interference from drafts or unwanted ingress 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. According to the invention, this object is achieved by the characterizing features of claim 1. Further advantageous refinements and improvements 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 by one arranged on the car roof Supply air device and at least one embedded in the floor of the car body Exhaust air opening is formed. It should be noted that those arranged on the roof Supply air devices are already known in many forms, for example in the form of scheduled or retrofitted on the car roof Air conditioning systems that supply conditioned fresh air into the vehicle interior. However, there was an arrangement of exhaust vents in the floor area apart from that, because of an unfavorable design, an unfavorable temperature distribution, the occurrence of drafts and annoyance from a high noise level cannot be ruled out.

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 with a Wagon body floor arranged air duct is connected. Here, the Air duct compared to one that communicates directly with the outside air Exhaust air opening, as it were, a barrier for direct exposure to the Vehicle interior due to driving noise, moisture and pollution, because these must first flow through the air duct before entering the car interior can reach.

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 be or advantageously arranged below the car body floor and formed by a collar molded onto the body of the car body be 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 manufacture because the air duct is made of Flat material, in particular made of sheet metal or possibly made of Plastic panels that can be molded. The design with a collar ensures a uniform air outlet, according to the design the collar of this as a chicane for one backwards, that is, inside the car, directed flow works.

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 extends in the air duct over its length and is formed like a gap. The longitudinal gap is open to the middle of the car to prevent the rolling noise to complicate the wheels of the rail vehicle.

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 determined according to 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. As a result, sufficient, largely uniform air removal is achieved and good air circulation is ensured.

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.For the disturbing inflow of external air and the penetration of moisture are to be prevented, at least below each exhaust air opening in the air duct Air baffles are arranged. It can be provided that the air baffles overlap and are inclined and thus the penetration of moisture and prevent foreign objects through the exhaust air 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.To prevent noise from entering the interior of the car body be provided according to an advantageous embodiment of the invention, that the air duct with sound-absorbing at least in the area of the gap-like opening Material is lined, 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 is on Vehicle floor with a cover, preferably a grille, for example 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.To reduce the risk of stumbling and to favor floor cleaning advantageously provided that the cover of each exhaust opening is flush with the floor of the car body. Fall with 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 one The air duct on the car body is removable for easy replacement if damaged appropriate.

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 device for loading and Ventilation not only in air-conditioned vehicles, that is, in vehicles which provided a cooling device for cooling the air for the passenger compartment is, is an advantage, but also in a conventional heating ventilation system. at Vehicles that are equipped with such a system do exist Air flow that is up to three times higher than that of fully air-conditioned vehicles Case is.

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 Heizund Klimaanlagen mit Lüfterbetrieb aufbauen.Furthermore, with the device according to the invention, the excess pressure in the interior of the car avoided that with the ever better sealing of modern rail vehicles can lead to problems, for example difficult automatic opening the vehicle doors. Such overpressure can occur especially in heating and Install air conditioners with fan operation.

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

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.Using an exemplary embodiment shown in the schematic drawing the invention, advantageous refinements and improvements and special Advantages of the invention are explained and described in more detail.

In Fig. 1 ist ein Querschnitt durch einen Wagenkasten 10 eines nicht näher dargestellten Schienenfahrzeuges zur Personenbeförderung gezeigt, der von Seitenwänden 12, 13, von einem Wagenkastenboden 14 und von einem Dach 16 begrenzt ist. Im Innenraum 11 des Wagenkastens 10 sind Sitzplätze 18 für Fahrgäste angeordnet.In Fig. 1 is a cross section through a car body 10 of a not shown Rail vehicle shown for passenger transport from the side walls 12, 13, bounded by a car body floor 14 and by a roof 16 is. In the interior 11 of the car body 10 there are seats 18 for passengers arranged.

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 there is an air conditioning system and a device 20 for the ventilation of the car body 10 associated supply air device 22 arranged, which via two supply air openings 24 in the roof 16 with the interior 11 is connected and through this the interior as needed heated or cooled fresh air. Using two drawn Arrows 26, which are each assigned to one of the two supply air openings 24, is the Flow path for the fresh air shown. This illustration shows that the fed Fresh air flows through the cross section of the interior 11 and below the Seating 18 flows out 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 in the floor of the vehicle body recesses formed, which are close to the edge along the Longitudinal outside, as in particular from the oblique view of the cut car body 10 can be seen in the longitudinal direction to each other are staggered.

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 shown in the schematic representation of FIG. 2 Car body 10 without windows, doors or entry areas the supply air device 22 is arranged approximately in the middle of the body and extends over the entire width of the body 10. Over a Inlet opening 23 is sucked in ambient air into the supply air device 22, therein processed, i.e. cleaned with a filter, heated or cooled and then in the Interior 11 promoted. There the supplied air leaves the interior after it Flow through the exhaust air openings provided on the car body floor 12 28, which in turn has an air duct shown in FIG. 1 and more clearly in FIG. 3 30 is connected.

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 made from plastic sheets. It delimits a space 32 with a rectangular shape Cross section in which first and second air baffles 34, 35 are arranged and to which a gap-like space 36 connects, which has a sound-absorbing Layer 37 is provided and is open to the middle of the carriage, so that the over Exhaust air openings 28 flow out used air to the environment can.

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. The exhaust air openings 28 are, as shown in FIG. 3, each with an air-permeable, provided, for example, as a grille or perforated sheet 38, which are flush with the body floor 14 or with one floor covering 15 arranged thereon completes.
