Description
Die Erfindung betrifft eine Sandstreueinrichtung, insbe sondere für Schienenfahrzeuge, mit einem im Bereich eines Rades angeordneten Sandrohr, das in einem Abstand ober halb der Schiene endet.The invention relates to a sand spreading device, in particular especially for rail vehicles, with one in the range Rades arranged sand pipe, which is at a distance above ends half of the track.
Eine Sandstreueinrichtung mit dem vorgenannten Merkmalen ist bei Schienenfahrzeugen allgemein bekannt. Das Sand rohr ist in der Regel am Rahmen beispielsweise eines Fahrwerks gehalten, wobei sich zwischen dem Rahmen und dem jeweiligen Rad eine Primärfederung befindet. Bei der Bemessung des Abstandes zwischen dem Sandrohr und der Schiene sind der maximale Federweg der Primärfederung und ein Sicherheitsmaß zu berücksichtigen, so daß auch bei tiefster Einfederung und möglicherweise auf der Schiene liegenden kleineren Fremdkörpern keine Kollisionen des Sandrohres vorkommen können. Dieser sich daraus ergebende Abstand ist häufig jedoch so groß, daß eine beträchtliche Sandmenge neben die Schiene fällt, also nicht wirksam zur Verfügung steht. Außerdem kann in das relativ hoch oberhalb der Schiene endende. Sandrohr im Fahrbetrieb eher Spritzwasser eindringen mit der ungünstigen Folge eines Zubackens des Sandrohres.A sand spreading device with the aforementioned features is generally known in rail vehicles. The sand pipe is usually one on the frame, for example Chassis held, being between the frame and there is primary suspension for each wheel. In the Dimensioning the distance between the sand pipe and the Rail are the maximum travel of the primary suspension and a safety measure to be taken into account, so that also at deepest deflection and possibly on the rail lying smaller foreign bodies no collisions of the Sand pipe can occur. This resulting one However, the distance is often so large that it is considerable Amount of sand falls next to the rail, so it is not effective for Available. It can also be quite high ending above the rail. Sand pipe when driving Splash water penetrate with the unfavorable consequence of a Grab the sand pipe.
Der Erfindung liegt die Aufgabe zugrunde, eine Sand streueinrichtung der gattungsgemäßen Art auf besonders einfache und kostengünstige Weise hinsichtlich der Streuwirkung und der Zuverlässigkeit im Betrieb auch unter ungünstigen Witterungsbedingungen (starker Regen, Frost) zu verbessern. The invention has for its object a sand Spreading device of the generic type in particular simple and inexpensive way in terms of Scattering effect and reliability in operation too under unfavorable weather conditions (heavy rain, Frost).
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Sandrohr ein den Abstand zur Schiene verkleinernder Sandaustrittskörper aus elastischem Werkstoff frei schwingend angebracht ist, der eine gegenüber der lichten Weite des Sandrohres wesentlich größere Sandaustritts öffnung aufweist.This object is achieved in that on Sand pipe reducing the distance to the rail Sand outlet body made of elastic material free is swinging attached, one opposite the light one Width of the sand pipe significantly larger sand outlet opening.
Durch den Gegenstand nach der Erfindung wird erreicht, daß praktisch die gesamte Menge des Streusandes gut verteilt auf die Schiene gelangt. Im Falle eines Zusam mentreffens mit ggf. auf der Schiene liegenden kleineren Fremdkörpern weicht der Sandaustrittskörper einfach elastisch aus. Wegen der Elastizität des Sandaustritts körpers und dessen frei schwingender Anbringung kommt es während der Fahrt zu permanenten Bewegungen, die durch Auslenkungen des Fahrwerks und den Fahrtwind unterstützt werden. Durch diese permanenten Bewegungen wird ein Festbacken des Streusandes im Sandaustrittskörper ver hindert, wobei dessen tiefliegende Plazierung einem Feuchtigkeitseintritt ohnehin entgegenwirkt. Im übrigen ist die auch von den Kosten her günstige erfindungsgemäße Lösung an beliebigen Fahrzeugen nachrüstbar.The object of the invention achieves that practically the entire amount of sand is good distributed on the rail. In the case of a together meeting with smaller ones that may be on the rails The sand outlet body simply gives way to foreign bodies elastic out. Because of the elasticity of the sand outlet body and its freely vibrating attachment while driving to permanent movements caused by Deflections of the landing gear and the airstream are supported become. Through these permanent movements a Baking of the sand in the sand outlet body ver hinders, its low-lying placement one Moisture ingress counteracts anyway. Furthermore is the cost-effective according to the invention Solution can be retrofitted to any vehicle.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are in the Subclaims specified.
Im weiteren wird die Erfindung anhand eines Ausführungs beispiels näher beschrieben, das in der Zeichnung schematisch dargestellt ist. Es zeigenFurthermore, the invention is based on an embodiment example described in more detail in the drawing is shown schematically. Show it
Fig. 1 den unteren Bereich eines Schienenfahrzeuges mit einer Sandstreueinrichtung, Fig. 1 the lower part of a rail vehicle with a sanding device,
Fig. 2 die Seitenansicht zu Fig. 1. Fig. 2 shows the side view of FIG. 1,.
Zur Sandstreueinrichtung gehört ein Sandrohr 1 aus Metall, das an einem primär gegenüber einem Rad 2 abge federten Rahmenteil 6 angeschraubt ist. Die bei einer Sandstreueinrichtung üblichen sonstigen Baugruppen - wie Vorratsbehälter, Dosiergerät und Verbindungsschlauch zum Sandrohr 1 - sind hier weggelassen, da deren jeweilige Ausführung von der Erfindung unabhängig ist.The sand-spreading device includes a sand pipe 1 made of metal, which is screwed to a frame part 6 , which is primarily spring-loaded relative to a wheel 2 . The other assemblies customary in a sand spreading device - such as a storage container, metering device and connecting hose to the sand pipe 1 - are omitted here, since their respective design is independent of the invention.
Am Sandrohr 1, das in einem Abstand a oberhalb der Schiene 3 (SO = Schienenoberkante) endet, ist ein Sand austrittskörper 4 aus elastischem Werkstoff mit Hilfe eines Klemmelements 5 freischwingend angeschlossen. Durch diesen Sandaustrittskörper 4 wird der besagte Abstand a zur Schiene 3 auf den Abstand b verkleinert, der im wesentlichen dem maximalen Einfederweg der Primärfederung entspricht. Der nach Art eines Faltenbalges gestaltete Sandaustrittskörper 4 weist eine Sandaustrittsöffnung 4a auf, die wesentlich größer ist als die lichte Weite des Sandrohres 1. Ein solcher Sandaustrittskörper 4 kann die Form eines Kegelstumpfes haben oder - wie aus Fig. 1 und 2 ersichtlich ist - an seiner Sandaustrittsöffnung 4a rechteckförmig ausgebildet sein, wobei die größere Länge dieses Rechtecks in Längsrichtung der Schiene 3 verläuft und die kürzere Seite etwa die Breite der Schiene 3 hat.On the sand pipe 1 , which ends at a distance a above the rail 3 (SO = rail top edge ) , a sand outlet body 4 made of elastic material is connected in a freely swinging manner with the aid of a clamping element 5 . This sand outlet body 4 reduces the said distance a to the rail 3 to the distance b, which essentially corresponds to the maximum deflection of the primary suspension. The sand outlet body 4 , designed in the manner of a bellows, has a sand outlet opening 4 a, which is substantially larger than the clear width of the sand pipe 1 . Such a sand outlet body 4 can have the shape of a truncated cone, or - as shown in Figures 1 and 2 it can be seen -. Be formed on its sand outlet opening 4 a rectangular shaped, extends the greater length of the rectangle in the longitudinal direction of the rail 3 and the shorter side approximately the width the rail 3 has.
Im Hinblick auf möglichst permanente schwingende Bewe gungen während der Fahrt ist der Sandaustrittskörper 4 aus elastischem Werkstoff entsprechend weich ausgeführt. Er weist vorzugsweise eine Härte nach Shore in der Grö ßenordnung von 60 auf.With regard to the most permanent possible vibrations while driving, the sand outlet body 4 is made of elastic material accordingly soft. It preferably has a Shore hardness of the order of 60.
