Description

Die Erfindung betrifft einen Eisenbahnwaggon mit Heiz- bzw. Klimaanlage, wobei unterhalb des unteren Randes der in der Waggonaußenwand angeordneten Fenster der Abteile ein Luftführungskanal verläuft, von dem ausgehend Zuleitungskanäle bis zu Ausströmöffnungen in der Höhe der unteren Fensterränder einerseits und oberhalb der oberen Fensterränder andererseits verlaufen, welche Zuleitungskanäle zur Waggoninnenseite hin von einer auch zur Abdeckung von Fensterrändern dienenden zumindest einen Teil des senkrechten Bereichs der Innenseite der Waggonaußenwand oberhalb des Luftführungskanals überdeckenden Zwischenwand begrenzt sind.The invention relates to a railway wagon with heating or air conditioning, an air duct running below the lower edge of the compartment windows arranged in the outer wall of the wagon, from which supply ducts run to outlet openings at the height of the lower window edges on the one hand and above the upper window edges on the other hand Which supply channels are delimited to the inside of the wagon by an intermediate wall which also covers at least part of the vertical region of the inside of the outside of the wagon above the air duct and also serves to cover window edges.

Eine derartige Anordnung ist beispielsweise aus der AT-PS 355.618 bekannt, und ermöglicht zufolge der Ausströmung der erwärmten bzw. klimatisierten Luft am unteren Fensterrand einerseits und oberhalb des oberen Fensterrandes andererseits eine sehr gleichmäßige und zugfreie Beheizung bzw. Klimatisierung des Waggonabteils. Nachteilig ist dabei allenfalls, daß die Montage der die Zuleitungskanäle zur Waggoninnenseite hin begrenzenden Zwischenwand relativ aufwendig ist, da für eine ausreichende Abdichtung gegen die Innenseite der Waggonaußenwand bzw. gegen die Fensterränder sowie auch für die Einhaltung des erforderlichen Abstandes zu dieser Innenseite zur Sicherstellung der notwendigen Querschnitte für die Luftführung gesorgt werden muß.Such an arrangement is known, for example, from AT-PS 355.618, and, due to the outflow of the heated or air-conditioned air at the lower window edge on the one hand and above the upper window edge on the other hand, enables very even and draft-free heating or air conditioning of the wagon compartment. The disadvantage here is that the installation of the intermediate wall delimiting the supply ducts to the inside of the wagon is relatively complex, since for a sufficient seal against the inside of the outside of the wagon or against the window edges and also for maintaining the required distance from this inside to ensure the necessary Cross sections for the air flow must be provided.

Aufgate der vorliegenden Erfindung ist es, unter Seibehaltung cer genannten Vorteile der bekannten Anordnung hinsichtlich der Verteilung der einströmenden Luft in das Abteil eine Verbesserung der genannten bekannten Anordnung dahingehend zu erreichen, daß insbesonders die Montage der gesagten Anordnung vereinfacht und mit einfachen Mitteln eine geräuscharme, optisch ansprechende, geschlossene Konstruktion insbesonders im Hinblick aus die Luftführungskanäle erreicht wird.Ongate of the present invention is, while maintaining the advantages of the known arrangement with respect to the distribution of the inflowing air into the compartment, to achieve an improvement in the known arrangement in such a way that, in particular, the assembly of the said arrangement is simplified and, with simple means, a low-noise, optical appealing, closed construction is achieved in particular with regard to the air ducts.

Dies wird gemäß der Erfindung dadurch erreicht, daß die Zwischenwand als abteilseitige Begrenzung eines hohlen Rahmens ausgebildet ist, der die Zuleitungskanäle enthält und mit Überleitungsöffnungen des Luftführungskanals in Verbindung steht. Die Zuleitungskanäle zu den Ausströmöffnungen sind also unabhängig von der Innenseite der Waggonaußenwand in dem hohlen Rahmen ausgebildet, womit dieser bei der Montage des Eisenbahnwaggons nur mehr auf sehr einfache Weise an dieser Innenseite befestigt werden muß; dabei sind keinerlei Anforderungen hinsichtlich der Abdichtung bzw. der Einhaltung eines genauen Abstandes mehr zu erfüllen, was - bei gleichzeitiger Sicherstellung der optimalen Funktion - die Montagearbeit sehr vereinfacht.This is achieved according to the invention in that the intermediate wall is designed as a compartment-side boundary of a hollow frame which contains the supply ducts and is connected to transfer openings of the air duct. The supply channels to the outflow openings are thus formed independently of the inside of the outer wall of the wagon in the hollow frame, which means that this only has to be attached to this inside in a very simple manner when the railway wagons are assembled; there are no more requirements with regard to sealing or maintaining a precise distance, which - while ensuring the optimal function - simplifies assembly work.

Gemäß einer Ausgestaltung der Erfindung sind im Inneren des hohlen Rahmens Luftführungseinrichtungen zur strömungsmäßigen Separierung der Zuleitungskanäle angeordnet. Diese Luftführungseinrichtungen können also bereits vor der Montage des hohlen Rahmens im Eisenbahnwaggon in diesem Rahmen beispielsweise bereits im Zuge von dessen Herstellung vorgesehen werden, was die Montagearbeiten im Eisenbahnwaggon nicht weiter belastet.According to one embodiment of the invention, air guiding devices for the flow separation of the supply ducts are arranged inside the hollow frame. These air guiding devices can therefore already be provided in this frame, for example in the course of its manufacture, even before the hollow frame is installed in the railway wagon, which does not further burden the assembly work in the railway wagon.

Gemäß einer vorteilhaften Ausgestaltung kann in diesem Zusammenhang auch vorgesehen sein, daß die Luftführungseinrichtungen verstellbare, z.B. von der Regelung der Heiz- bzw. Klimaanlage beeinflußbare, Steuereinrichtungen, insbesondere Klappen aufweisen, die die freien Durchströmquerschnitte der Zuleitungskanäle im hohlen Rahmen kontrollieren. Diese Klappen können beispielsweise so ausgebildet sein, daß sie nach der Montage des Rahmens im Eisenbahnwaggon einmal im'Hinblick auf optimale Ausströmbedingungen aus den verschiedenen Ausströmöffnungen eingestellt werden und im Betrieb der Heiz- bzw. Klimaanlage nicht mehr verstellt werden. Vorteilhaft wäre auch, eine Verstellung dieser Steuereinrichtungen durch die Regelung der Heiz- bzw. Klimaanlage vorzusehen. So könnten beispielsweise die am unteren Fensterrand angeordneten Ausströmöffnungen, die hauptsächlich im Heizbetrieb ein Beschlagen der Fenster verhindern sollen, durch Abschließen der zugehörigen Zuleitungskanäle im Kühlbetrieb geschlossen werden.According to an advantageous embodiment, it can also be provided in this connection that the air duct devices adjustable, for example, can be influenced by the regulation of the heating or air conditioning, control devices, in particular flaps, which control the free flow cross-sections of the supply channels in the hollow frame. These flaps can be designed, for example, so that once the frame has been installed in the railway wagon, they are once set for optimal outflow conditions from the various outflow openings and can no longer be adjusted during operation of the heating or air conditioning system. It would also be advantageous to provide an adjustment of these control devices by regulating the heating or air conditioning system. For example, the outflow openings arranged at the lower edge of the window, which are intended primarily to prevent the windows from fogging up in heating mode, could be closed by closing off the associated supply ducts in cooling mode.

Besonders vorteilhaft ist es, wenn der hohle Rahmen einteilig ausgeführt und an der Innenseite der Waggonaußenwand anbringbar ist, da damit die Montagearbeit lediglich auf Einrichten und Befestigen eines einzigen Bauteils an der Innenseite der Waggonaußenwand beschränkt ist.It is particularly advantageous if the hollow frame is made in one piece and can be attached to the inside of the outer wall of the wagon, since the assembly work is thus limited to setting up and fastening a single component on the inside of the outer wall of the wagon.

Der Rahmen kann gemäß einer Ausgestaltung der Erfindung als Kunststoffspritzteil ausgeführt sein, was einerseits eine kostengünstige Herstellung ermöglicht und andererseits auch Vorteile im Zusammenhang mit der Wärmeisolierung und Schalldämmung bringt.According to one embodiment of the invention, the frame can be designed as a plastic injection-molded part, which on the one hand enables cost-effective production and on the other hand also brings advantages in connection with thermal insulation and sound insulation.

Zur weiteren Vereinfachung der Montage des Eisenbahnwaggons ist vorgesehen, daß der hohle Rahmen mittels einer Dichtung gegenüber der Waggonaußenwand abgedichtet ist, die auch zur Halterung und Abdichtung des Fensters dient. Dabei muß lediglich der das vormontierte Fenster enthaltende Rahmen als vpr,pmtoerter Bauteil bei der Endmontage des Waggons an entsprechender Stelle der Innenseite der Außenwand angebracht, verbunden und abgedichtet werden.To further simplify the assembly of the railway wagon, it is provided that the hollow frame is sealed by means of a seal against the outer wall of the wagon, which also serves to hold and seal the window. All that has to be done is the pre-assembled window holding frames as vpr, pmtoERT component are attached, connected and sealed at the appropriate place on the inside of the outer wall during the final assembly of the wagon.

Gemäß einer anderen Ausgestaltung der Erfindung kann vorgesehen sein, daß der hohle Rahmen aus mehreren Teilen besteht, welche je für sich einen separaten, zu einer Ausströmöffnung bzw. einer Gruppe von Ausströmöffnungen führenden Zuleitungskanal bilden. Auf diese Weise können beispielsweise für jede der vorgesehenen Ausströmöffnungen eigene jeweils aneinander anschließende Rahmenteile vorgesehen sein, deren Herstellung gegenüber einem einzigen, die ganze Abteilwand bedeckenden Bauteil vereinfacht ist und die trotzdem vom Abteil aus gesehen eine einzige, praktisch durchgehende Zwischenwand zur Abteilinnenseite hin bilden.According to another embodiment of the invention, it can be provided that the hollow frame consists of several parts, each of which forms a separate feed channel leading to an outflow opening or a group of outflow openings. In this way it is possible, for example, for each of the outflow openings provided to have its own adjacent frame parts, the manufacture of which is simplified compared to a single component covering the entire compartment wall and which, however, form a single, practically continuous partition wall from the compartment towards the inside of the compartment.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß der hohle Rahmen zusammen mit zumindest einem Teil des im Abteil verlaufenden Luftführungskanals eine vormontierbare Baueinheit bildet. Damit ist auf sehr einfache Weise die Montage der in jedem Abteil vorhandenen Teile der Luftführung erleichtert, da der eigentliche Luftführungskanal mit dem die Zuleitungskanäle enthaltenden hohlen Rahmen vormontierbar ist und somit bei der eigentlichen Montage im Abteil nur noch die Anschlüsse zu den sonstigen Teilen der Luftführung der Heiz- bzw. Klimaanlage hergestellt werden müssen.A further embodiment of the invention provides that the hollow frame forms a preassembled structural unit together with at least part of the air duct running in the compartment. This simplifies the assembly of the parts of the air duct in each compartment in a very simple manner, since the actual air duct can be preassembled with the hollow frame containing the inlet ducts and thus only the connections to the other parts of the air duct during the actual assembly in the compartment Heating or air conditioning must be manufactured.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß die Baueinheit im Bereich des Luftführungskanals an beiden Seiten Anschlußteile ausweist, die im eingebauten Zustand im Abteil gegen dort vorgesehene Anschlußöffnungen abdichten. Im Bereich der zusammenwirkenden Anschlußöffnungen bzw. -teile können bedarfsweise Dichtungen, Befestigungseinrichtungen (wie Schrauben. Befestigungswinkel od. dgl.) oder sonstige die Montage ermöglichende und eine sichere Abdichtung bewirkende Zusatzteile angebracht werden. Schließlich ist gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung vorgesehen, daß die Baueinheit als einstückiger Kunststoffspritzteil ausgebildet ist. Dadurch ist die Vormontage überflüssig und infolge der Leichtheit, sowie auch der wärmeisolierenden Eigenschaften von Kunststoff sind weitere Vorteile gegeben.In an advantageous embodiment of the invention it is provided that the structural unit in the area of the air duct has connection parts on both sides which, in the installed state, seal in the compartment against connection openings provided there. In the area of the interacting connection openings or parts, seals, fastening devices (such as screw ben. Fastening bracket or the like) or other additional parts that enable assembly and provide a secure seal. Finally, according to a particularly advantageous embodiment of the invention, it is provided that the structural unit is designed as a one-piece plastic injection-molded part. This eliminates the need for pre-assembly and, due to the lightness and the heat-insulating properties of plastic, there are further advantages.

Klimaanlage verstellt werden können.The supply channels 6, 7, 8 are delimited towards the inside of the wagon by an intermediate wall 14, which also serves to cover the window edges 3, 11, 12, 13 and covers at least part of the vertical area of the inside of the outside of the wagon 4 above the air duct 2, which serves as a compartment Limiting a hollow frame 15 is formed, which receives the supply channels 6,7,8 and is connected to transfer openings 16 (Fig. 2) of the air duct 2. This hollow frame has air guiding devices 17 for separating the supply ducts 6, 7, 8 in terms of flow, the free flow cross-sections being able to be controlled via adjustable flaps 18 or similar control devices and being adjusted, for example, as a function of the regulation of the heating or air conditioning system.

Bei einer Teilung der Baueinheit 32 in hohlen Rahmen 15 und Luftführungskanal 2, ist es auch möglichldie einzelnen Bestandteile aus jeweils geeigneten Materialien anzufertigen, beispielsweise Blech einerseits und Kunststoff andererseits.At a pitch of the assembly 32 in the hollow frame 15 and air duct 2, it is also possible to customize l of the single components from respective suitable materials, such as sheet metal on the one hand and on the other hand plastic.

In der Darstellung nach Fig. 1a ist auch zu erkennen, daß die Baueinheit 32 im Bereich des Luftführungskanals 2 an beiden Seiten Anschlußteile 33 aufweist, die in eingebautem Zustand der Baueinheit im Abteil 1 gegen dort - beispielsweise in Form von Stutzen od. dgl. - vorgesehene Anschlußöffnungen 34 abdichten. Bei der Montage allenfalls vorzusehende Dichtungen, Befestigungsteile, usw. sind nicht dargestellt.In the illustration according to FIG. 1a it can also be seen that the assembly 32 in the area of the air duct 2 has connection parts 33 on both sides, which in the installed state of the assembly in compartment 1 against it - for example in the form of connecting pieces or the like. Seal the intended connection openings 34. Any seals, fasteners, etc. to be provided during assembly are not shown.

Der hohle Rahmen 15 bzw. die Baueinheit 32 sind einstückig, beispielsweise als Kunststoffspritzteil ausgeführt, und weisen auch unmittelbar die Ausströmöffnungen 9 (Fensterunterkante) und 10 (Fensteroberkante) auf. Es ist auch möglich, den Rahmen als Blechpreßteil auszubilden und zumindest an der Abteilinnenseite mit einer vorzugsweise geräusch- bzw. wärmedämmenden Beschichtung zu versehen. Zusätzlich dazu könnten in beiden Fällen auch im Bereich der seitlichen Fensterränder 12, 13 Ausströmöffnungen vorgesehen sein, die jeweils zum gegenüberliegenden Fensterrand ausgerichtet wären, da infolge des zur Verfügung stehenden relativ großen Querschnittes der Buleitungskanäle nur geringe Strömungsgesohwindigkeiten vorgesehen werder. müssen und somit keine Belästigung der jewils am Fensterplatr gegenüber sitmender. Reisenden zu befürchten ist, Für diese Ausströmöffnungen könnten auch gegebenenfalls zusätzliche Luftführungseinrichtungen bzw. Steuereinrichtungen vorgesehen sein.The hollow frame 15 or the structural unit 32 are made in one piece, for example as a plastic injection-molded part, and also have the outflow openings 9 (lower window edge) and 10 (upper window edge). It is also possible to design the frame as a pressed sheet metal part and to provide it with a preferably noise or heat-insulating coating at least on the inside of the compartment. In addition to this, in both cases, outflow openings could also be provided in the area of the lateral window edges 12, 13, each of which would be aligned with the opposite window edge, since the relatively large cross section of the Pipeline channels only low flow velocities are provided. must and therefore no annoyance of the jewils on the window plate opposite sitmender. Travelers are to be feared, additional air guidance devices or control devices could also be provided for these outflow openings.

Wie insbesonders aus Fig. 2 ersichtlich ist, kann der hohle Rahmen 15 im Bereich des Zuleitungskanals 7 zur Ausströmöffnung 9 an der Fensterunterkante 3 eine Einlaßöffnung 19 zur Zufuhr von Abteilumluft aufweisen. Durch die Anordnung dieser Einlaßöffnungen 19 wird die Ausbildung des hohlen Rahmens 15 nicht wesentlich komplizierter und kann auch die im Abteil vorhandene Warmluft zur Beschlagfreihaltung des Fensters 5 herangezogen werden. Dabei kann es von Vorteil sein, wenn im Bereich der Einlaßöffnung 19 ein zusätzlicher Heizkörper im Rahmen angeordnet ist, der zur Aufwärmung der dem Fenster 5 zuzuführungen Mischluft dient.As can be seen in particular from FIG. 2, the hollow frame 15 can have an inlet opening 19 in the region of the supply duct 7 to the outflow opening 9 at the lower window edge 3 for the supply of compartment air. The arrangement of these inlet openings 19 does not make the formation of the hollow frame 15 much more complicated and the warm air present in the compartment can also be used to keep the window 5 free of fogging. It may be advantageous if an additional heating element is arranged in the frame in the area of the inlet opening 19, which serves to heat the mixed air supplied to the window 5.

Durch diese Ausbildung der Zuleitungskanäle zu den Ausströmöffnungen der Heiz- bzw. Klimaanlage in dem gleichzeitig große Teile der Innenseite der Waggonaußenwand bedeckenden hohlen Rahmen bzw. der Baueinheit 32,ist insbesonders eine große Erleichterung der Montage gegeben, da einerseits die aufwendige Abdichtung der Zuleitungskanäle und andererseits die Justierung eines definierten Abstandes der Zwischenwand 14 zur Innenseite der Waggonaußenwand wegfällt und nur noch ein kompletter Teil an der Innenseite der Fensterwand montiert zu werden braucht. In diesem Zusammenhang wäre es zur Erleichterung der Herstellung bzw. Montage aber auch möglich, den hohlen Rahmen beispielsweise entlang der Luftführungseinrichtungen 17' und des dann bis zu den oberen Ausströmöffnungen anschließenden Fensterrandes zu teilen, wobei nach der Montage aber nach wie vor eine zumindest weitgehend geschlossene einheitliche Abteilinnenwand gegeben wäre.This design of the supply ducts to the outflow openings of the heating or air conditioning system in the hollow frame or the structural unit 32, which at the same time covers large parts of the inside of the outside of the wagon, greatly facilitates assembly, since on the one hand the complex sealing of the supply ducts and on the other hand the adjustment of a defined distance of the intermediate wall 14 to the inside of the outside of the wagon is eliminated and only a complete part needs to be installed on the inside of the window wall. In this context, it would also be possible to facilitate the manufacture or assembly by dividing the hollow frame, for example, along the air guiding devices 17 'and the window edge which then adjoins up to the upper outflow openings, but still at least largely closed after the assembly uniform compartment inner wall would be given.

Der Vollständigkeit, halber ist noch darauf hinzuweisen, daß in Fig. 1 bzw. Fig. 1a mit 20 eine Deckenleuchte, mit 21 die Gepäckträger, mit 22 die Sitze, mit 23 die Abstelltischchen, mit 24 ein Abfallbehälter und mit 25 und 26 die Abteilseitenwände bezeichnet sind.For the sake of completeness, it should also be pointed out that in Fig. 1 or Fig. 1a with 20 a ceiling lamp, with 21 the luggage rack, with 22 the seats, with 23 the storage tables, with 24 a waste container and with 25 and 26 the compartment side walls are designated.

In der Schnittdarstellung der Fig. 4 ist ersichtlich, daß der Querschnitt des hohlen Rahmens und damit des Zuleitungskanals 6 relativ groß gewählt werden kann, sodaß sich niedere Durchströmgeschwindigkeiten ergeben, was sich insbesonders auch in einer sehr niederen Geräuschentwicklung bemerkbar macht. Soferne in diesem Bereich - wie erwähnt - seitliche Ausströmöffnungen vorgesehen werden, ist eine Belästigung von am Fensterplatz gegenübersitzenden Reisenden durch direkte Zugwirkung ausgeschlossen.In the sectional view of FIG. 4 it can be seen that the cross section of the hollow frame and thus of the feed channel 6 can be chosen to be relatively large, so that low flow rates result, which is particularly noticeable in a very low noise level. If, as mentioned, lateral outflow openings are provided in this area, annoyance to passengers sitting opposite at the window seat by direct train action is excluded.

Im Detail der Fig. 5 ist schließlich noch eine Möglichkeit dargestellt, die Zuleitungskanäle 6 bzw. 8 im Bereich der Oberkante 27 des hohlen Rahmens 15 in eine überströmöffnung 28 münden zu lassen, welche die zugeführte Luft hinter die Innenhaut 29 des gewölbten Waggondaches 30 führt, von wo sie über Ausströmöffnungen 31 austreten kann. Auf diese Weise kann unter Umständen eine weitere Verbesserung der Verteilung der geheizten bzw. klimatisierten Luft im Abteil erreicht werden.Finally, in detail in FIG. 5, a possibility is shown of having the supply ducts 6 and 8 open into an overflow opening 28 in the region of the upper edge 27 of the hollow frame 15, which leads the supplied air behind the inner skin 29 of the curved wagon roof 30, from where it can exit through outflow openings 31. In this way, a further improvement in the distribution of the heated or conditioned air in the compartment can be achieved under certain circumstances.
