Description

Schienengebundene Fahrzeuge entwickeln vor allem bei höherer Geschwindigkeit und relativ kleinem Raddurchmesser Lärm, der vor allem bei Straßenbahnen, die in dicht besiedeltem Gebiet verkehren, als störend empfunden wird.Jedoch treten solche Probleme auch bei Eisenbahnfahrzeugen auf, da dort vor allem durch die angestrebten hohen Geschwindigkeiten mit bedeutender Lärmentwicklung zu rechnen ist.Rail-bound vehicles develop noise, especially at higher speeds and relatively small wheel diameters, which is particularly annoying for trams that travel in densely populated areas, but such problems also occur with railway vehicles, as this is mainly due to the desired high speeds significant noise is to be expected.

Die Erfindung betrifft eine Einrichtung für schienengebundene Fahrzeuge, wobei im Bereich zwischen dem Bodenniveau und der Laufebene des Fahrzeuges Schalldämm-Material, insbes. in Plattenform, bevorzugt in sich vom Bodenniveau gegen den Bereich der Laufebene erstreckenden Schürzen der Fahrzeugseitenwände, angeordnet ist. Bei einem aus der DE-OS 23 36 700 bekanntwordenen schienengebundenen Fahrzeug wurde das Schalldämmaterial in Form von Platten im Bereich zwischen dem Bodenniveau und der Laufebene des Fahrzeuges angeordnet. Weiters ist dort das Schalldämmaterial in Schürzen angeordnet, die sich vom Bodenniveau gegen den Bereich der Laufebene erstrecken.The invention relates to a device for rail-bound vehicles, soundproofing material, in particular in plate form, preferably in aprons of the vehicle side walls extending from the floor level towards the area of the running plane, being arranged in the area between the floor level and the running level of the vehicle. In a rail-bound vehicle known from DE-OS 23 36 700, the soundproofing material was arranged in the form of plates in the area between the floor level and the running level of the vehicle. Furthermore, the soundproofing material is arranged in aprons that extend from the floor level to the area of the running level.

Problematisch bei derartiger Schalldämmaterialanordnung ist die Art und Weise der Montage des Schalldämmaterials und auch der Ersatz des Schalldämmaterials nach etwaigen Beschädigungen, sei dies durch Verrottung oder •auch durch Beschädigung der. Blechschürzen bei Unfällen u.dgl.The problem with such a sound insulation material arrangement is the manner in which the sound insulation material is installed and also the replacement of the sound insulation material after any damage, whether due to rotting or • also due to damage to the. Metal aprons in accidents and the like

Hier eine Lösung zu finden, ist Aufgabe der Erfindung, die darin gelegen ist, daß das Schall-Dämmaterial in Wannen, bevorzugt aus korrosionsbeständigem Material, z.B. aus glasfaserverstärktem Kunststoff, eingebettet ist und daß gegebenenfalls die Wannen durch mit Perforationen versehene Platten, z.B. aus Aluminiumblech, abgedeckt sind, die insbes. dem Inneren des Fahrzeuges zugeordnet sind. Die Wannen können einfach ein- und ausgebaut werden, womit eine schalldämmende Nachrüstung bereits bestehender Fahrzeuge möglich wird, jedoch auch ein Ersatz des schalldämmenden Materials durch ein anderes, möglicherweise besser geeignetes ermöglicht ist. Es können somit komplette Schalldämmelemente vorgefertigt und dann zu jedem gewünschten Zeitpunkt in das Fahrzeug eingebaut werden. Dies kann sowohl im Zuge der Neuherstellung geschehen als auch bei bereits in Betrieb befindlichen Fahrzeugen.Finding a solution here is the object of the invention, which is that the soundproofing material is embedded in trays, preferably made of corrosion-resistant material, for example made of glass fiber reinforced plastic, and that the trays are optionally provided with perforated plates, for example made of aluminum sheet , are covered, which are assigned in particular to the interior of the vehicle. The trays can be easily installed and removed, which makes it possible to retrofit existing vehicles with sound insulation, but also to replace the sound insulation material is made possible by another, possibly more suitable one. Complete sound insulation elements can thus be prefabricated and then installed in the vehicle at any desired time. This can happen both in the course of the new production as well as in vehicles already in operation.

Als Schalldämm-Material kann beispielswelse Tel-Wolle Verwendung finden, jedoch ist es ebenso möglich, schalldämmenden Schaumstoff, insbes. Polyurethanschaumstoff, einzusetzen.Tel-wool, for example, can be used as sound insulation material, but it is also possible to use sound insulation foam, in particular polyurethane foam.

Besonders zweckmäßig ist es, Lärm, der im Bereich der Drehgestelle, also in unmittelbarer Nähe der Räder des Fahrzeuges, entsteht, zu dämmen. Zu diesem Zweck wird in besonderer Ausgestaltung der Erfindung vorgesehen, daß das Schalldämm-Material in an sich bekannter Weise am Drehgestell, insbes. an dessen Bahnräumer gehalten ist und sich bevorzugt etwa von der der Laufebene zugekehrten Bahnräumerebene bis in den Bereich der Ebene der Laufachsen des Drehgestelles erstreckt.It is particularly expedient to dampen noise that arises in the area of the bogies, that is to say in the immediate vicinity of the wheels of the vehicle. For this purpose, it is provided in a special embodiment of the invention that the soundproofing material is held in a manner known per se on the bogie, in particular on its platform clearer, and preferably extends approximately from the leveling plane facing the running level to the area of the level of the axis of travel Bogie stretches.

Es hat sich als besonders zweckmäßig erwiesen, wenn zwischen dem Boden der Wanne und der dem Boden benachbarten Wand der Schürze ein Zwischenraum vorhanden ist. Durch diese Ausgestaltung ist es möglich zu vermeiden, daß etwaige Vibrationen der Wanne auf die Schürze übertragen werden, wodurch zusätzlich Lärm entstehen würde.It has proven to be particularly expedient if there is a space between the bottom of the tub and the wall of the apron adjacent to the bottom. With this configuration, it is possible to avoid any vibrations in the tub being transmitted to the apron, which would cause additional noise.

Besonders günstige Ergebnisse hinsichtlich der Schalldämmung können erreicht werden, wenn in besonderer weiterer Ausgestaltung der erfindungsgemäßen Einrichtung die Wanne nur an zwei einander gegenüberliegenden Rändern, z.B. durch Schrauben, mit der Schürze, bevorzugt über mit der Schürze verbundene Tragwinkel, verbunden ist. Auf diese Art und Weise wird eine besonders günstige Absorption des Schalles erreicht.Particularly favorable results with regard to sound insulation can be achieved if, in a special further embodiment of the device according to the invention, the trough only on two opposite edges, e.g. is connected by screws to the apron, preferably via support brackets connected to the apron. In this way, particularly favorable absorption of the sound is achieved.

Zwecks Schalldämmung des Drehgestellbereiches kann vorgesehen werden, daß die Wanne auf an den Seitenholmen des Bahnräumers befestigten Tragbügeln abgestützt ist. Diese Anbringungsart hat sich als besonders einfach herausgestellt.For the purpose of soundproofing the bogie area, it can be provided that the trough is supported on support brackets attached to the side rails of the rail clearer. This type of attachment has proven to be particularly simple displayed.

Die Wanne kann in besonderer Ausgestaltung der Erfindung mit einem Seitenrand zwischen zwei im wesentlichen vertikal von einem horizontal angeordneten Schenkel der Tragbügel aufragenden Leisten eingesetzt sein. Dies erlaubt eine besonders einfache Montage. Die Leisten können dabei Flanschen eines am horizontalen Schenkel des Tragbügels befestigten U-Profiles sein.In a special embodiment of the invention, the trough can be inserted with a side edge between two strips projecting substantially vertically from a horizontally arranged leg of the support bracket. This allows a particularly simple assembly. The strips can be flanges of a U-profile attached to the horizontal leg of the bracket.

Die Befestigung der Wanne am Tragbügel wird vereinfacht, wenn in besonderer Ausgestaltung der Erfindung in der Wanne mindestens zwei, insbesondere als Rohr ausgebildete, Steher angeordnet sind, deren jeder mittels einer Schraube od.dgl. Befestigungsmittel, an einem im wesentlichen vertikal angeordneten Schenkel des Tragbügels befestigt ist.The attachment of the trough to the support bracket is simplified if, in a special embodiment of the invention, at least two uprights, in particular in the form of a tube, are arranged in the trough, each of which is or the like using a screw. Fastening means is attached to a substantially vertically arranged leg of the bracket.

Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise näher erläutert. Es zeigt,

  • 1 is a side view of the insulation device according to the invention for rail-bound vehicles,
  • 2 on a larger scale than a section along the line II-II in Fig. 1,

In der Zeichnung ist mit 1 das Niveau des Bodens des (nicht dargestellten) Fahrgastraumes eines schienengebundenen Fahrzeuges, insbes. eines Straßenbahnwagens, bezeichnet. Die Laufebene des Fahrzeuges, d.i. die Schienenoberkante, ist mit 2 bezeichnet. Die Laufräder sind aus Gründen der Deutlichkeit weggelassen. Zwischen dem Bodenniveau 1 und der Laufebene 2 des Fahrzeuges ist in den Schürzen 4 der Fahrzeugseitenwand 5 Schalldämm-Material 3 angeordnet. Als Schalldämmaterial können dabei Platten aus TeI-Wolle Verwendung finden. Auch am Drehgestell 6 (Fig. 4 und 5) kann Schalldämm-Material 3 angeordnet werden. Das Schalldämm-Material 3 wird dabei bevorzugt am Bahnräumer 7 gehalten, der die Schwenkbewegungen des Drehgestelles mitmacht und über einen Träger 29 mit dem Rahmen 30 des Drehgestelles verbunden ist. Das Schalldämm-Material am Drehgestell ist bevorzugt so angeordnet, daß es sich vom Bereich der der Laufebene 2 zugewandten Bahnräumerebene 8 bis in den Bereich der Ebene der Laufachsen 9 des Drehgestelles erstreckt (Fig. 6). Solcherart wird eine günstige Schallabschirmung nach außen erreicht.In the drawing, 1 denotes the level of the floor of the (not shown) passenger compartment of a rail-bound vehicle, in particular a tram car. The running level of the vehicle, ie the top edge of the rail, is designated by 2. The impellers are omitted for clarity. Between the floor level 1 and the running level 2 of the vehicle is in the box zen 4 of the vehicle side wall 5 soundproofing material 3 arranged. Sheets of TeI wool can be used as soundproofing material. Sound insulation material 3 can also be arranged on the bogie 6 (FIGS. 4 and 5). The soundproofing material 3 is preferably held on the rail clearer 7, which follows the pivoting movements of the bogie and is connected to the frame 30 of the bogie via a support 29. The soundproofing material on the bogie is preferably arranged in such a way that it extends from the area of the leveling plane 8 facing the running plane 2 to the area of the plane of the running axes 9 of the bogie (FIG. 6). In this way, a favorable sound shielding from the outside is achieved.

Aus Montagegründen und auch aus Gründen der Vorfertigung ist es günstig, wenn das Schalldämm-Material 3 in Wannen 10 eingebettet wird. Die Wannen 10 bestehen aus korrosionsbeständigem Material. Besonders eignet sich hiefür glasfaserverstärkter Kunststoff. Es müssen dabei nicht alle am Schienenfahrzeug vorgesehenen Schürzen mit schalldämmendem Material ausgelegt werden. In den Schürzen können bekanntermaßen auch Elektrogeräte u.dgl. angeordnet sein. Solche Schürzen werden daher häufig nicht mehr mit Schalldämm-Material 3 versehen. Es kann dort jedoch der Elektrogerätekasten od.dgl. mit schalldämmender Masse versehen werden, um auch an diesen Stellen einen verbesserten Schallschutz zu erzielen.For assembly reasons and also for reasons of prefabrication, it is advantageous if the soundproofing material 3 is embedded in trays 10. The tubs 10 are made of corrosion-resistant material. Glass fiber reinforced plastic is particularly suitable for this. It is not necessary to cover all the aprons provided on the rail vehicle with sound-absorbing material. As is known, electrical appliances and the like can also be used in the aprons. be arranged. Such aprons are therefore often no longer provided with sound insulation material 3. However, there can be the electrical equipment box or the like. be provided with sound-absorbing material in order to achieve improved sound insulation in these areas as well.

Die Wannen 10 können durch Platten 12 nach außen verschlossen werden. Die Platten 12 müssen dabei (aus schalltechnischen Gründen) Perforationen 11 aufweisen. Die Platten können aus Aluminiumblech bestehen. Im montierten Zustand sind die Platten dem Inneren des Fahrzeuges zugekehrt, d.h. die in gegenüberliegenden Seitenwandschürzen des Fahrzeuges angeordneten Wannen 10 sind mit ihren Abdeckplatten 12 einander zugekehrt.The tubs 10 can be closed to the outside by plates 12. The panels 12 must have perforations 11 (for acoustic reasons). The plates can be made of aluminum sheet. When assembled, the panels face the interior of the vehicle, i.e. the tubs 10 arranged in opposite side wall aprons of the vehicle are facing each other with their cover plates 12.

Zwischen dem Boden 14 der Wannen 10 und der dem Boden benachbarten Wand der Schürze 4 ist ein Zwischenraum 15 vorhanden. Die Wanne 10 ist nur an zwei einander gegenüberliegenden Rändern 16, 17 mit der Schürze 4 verbunden. Bevorzugt werden zur Verbindung Schrauben 18 verwendet. Die Anzahl der für die Befestigung zu verwendenden Schrauben hängt dabei von der Größe der Wanne bzw. der Schürze ab, in welche die Wanne eingebaut wird. Zur Verbindung der Wannen 10 mit der jeweiligen Schürze 4 dienen Tragwinkel 19, 20, die ihrerseits mit der Schürze, z.B. durch Schweißen, verbunden sind. Auf den Drehgestellen wird die Wanne 10 von Tragbügeln abgestützt, die an den Seitenholmen des Bahnräumers,z.B. mittels Schrauben 31, befestigt sind. Die Wanne 10 wird auf den Tragbügel 21 aufgesetzt. Hiebei wird die Wanne 10 mit einem Seitenrand 22 zwischen zwei im wevertikal von einem horizontal angeordneten Schenkel 23 der Tragbügel 21 aufragenden Leisten 24 eingesetzt, wie dies Fig. 6 erkennen läßt.A space 15 is present between the bottom 14 of the tubs 10 and the wall of the apron 4 adjacent to the bottom. The tub 10 is connected to the apron 4 only at two mutually opposite edges 16, 17. Screws 18 are preferred for connection turns. The number of screws to be used for fastening depends on the size of the tub or apron in which the tub is installed. Support brackets 19, 20, which in turn are connected to the apron, for example by welding, are used to connect the tubs 10 to the respective apron 4. On the bogies, the trough 10 is supported by support brackets which are fastened to the side rails of the rail clearer, for example by means of screws 31. The tub 10 is placed on the bracket 21. The trough 10 is inserted with a side edge 22 between two strips 24 projecting vertically from a horizontally arranged leg 23 of the support bracket 21, as can be seen in FIG. 6.

Die Leisten 24 werden bevorzugt von den Flanschen eines am horizontalen Schenkel 23 des Tragbügels 21 befestigten U-Profiles 25 gebildet. Das U-Profil 25 kann dabei durch Schweißen mit dem horizontalen Schenkel 23 des Tragbügels 21 verbunden sein.The strips 24 are preferably formed by the flanges of a U-profile 25 fastened to the horizontal leg 23 of the mounting bracket 21. The U-profile 25 can be connected by welding to the horizontal leg 23 of the bracket 21.

Wie die Fig. 4 und 6 zeigen, sind in der Wanne Steher 26 angeordnet. Diese Steher können von Rohren gebildet werden. Jeder Steher 26 ist mittels einer Schraube 27 an einem vertikalen Schenkel 28 des Tragbügels 21 befestigt.As shown in FIGS. 4 and 6, uprights 26 are arranged in the tub. These uprights can be formed by pipes. Each upright 26 is fastened to a vertical leg 28 of the support bracket 21 by means of a screw 27.
