Description
Die Erfindung betrifft Außenleuchten an Fahrzeugen mit Merkmalen wie in den Oberbegriffen der Ansprüche 1 und 2 angegeben.The invention relates to outdoor lights on vehicles with features as indicated in the preambles of claims 1 and 2.
Die Erfindung geht aus von der
Bei diesem Fahrzeug mit den wie vorstehend angegebenen luftdurchströmten Scheinwerfern handelt es sich aber um ein solches für normale Einsatzzwecke.However, this type of vehicle with the headlamps through which air flows as indicated above is one for normal use.
Die Erfindung dagegen befasst sich mit der Lösung von Problemen, die bei so genannten watfähigen Kraftfahrzeugen auftreten. Unter watfähigen Kraftfahrzeugen versteht man z. B. Katastropheneinsatzfahrzeuge oder Militärfahrzeuge, die aufgrund ihres Einsatzzweckes in der Lage sein müssen, auch zumindest teilweise unter Wasser in einer Wassertiefe von beispielsweise 1,5 Meter mit geringer Geschwindigkeit, aber ansonsten uneingeschränkt gefahren werden zu können.The invention, however, deals with the solution of problems that occur in so-called watfähige vehicles. Under watfähige vehicles are understood z. As disaster response vehicles or military vehicles, which must be able to be driven at least partially under water in a water depth of, for example 1.5 meters at low speed, but otherwise unrestricted because of their purpose.
Um eine Watfähigkeit solcher Kraftfahrzeuge sicherstellen zu können, sind viele Zusatzmaßnahmen gegenüber nicht-watfähigen Kraftfahrzeugen erforderlich. Beispielsweise muss die Ansaugstelle für die Motorverbrennungsluft über der Wathöhe liegen. Ferner müssen die Antriebsachsen mit ihren Achsgetrieben absolut wasserdicht ausgebildet sein und deren Be- und Entlüftungsstellen müssen ebenfalls über der Wathöhe liegen. Auch die Elektrik muss wasserdicht ausgebildet, z. B. gekapselt oder über der Wathöhe angeordnet sein. Die Außenleuchten von watfähigen Fahrzeugen wurden bisher hermetisch wasserdicht ausgebildet, und zwar durch spezielle Dichtungen und dickere Gehäusewandungen und Streulichtscheiben. Solche hermetisch dichten Außenleuchten sind größer und schwerer sowie auch erheblich teurer als entsprechende Außenleuchten von nicht-watfähigen Fahrzeugen.In order to ensure a wading capability of such vehicles, many additional measures are required in relation to non-watertight motor vehicles. For example, the intake point for the engine combustion air must be above the wath height. Furthermore, the drive axles must be designed absolutely watertight with their final drives and their ventilation points must also lie above the wath height. The electrical system must be waterproof, z. B. encapsulated or arranged over the wad. The exterior lights of watertight vehicles have been hermetically waterproof to date, through special seals and thicker housing walls and diffuser lenses. Such hermetically sealed exterior lights are larger and heavier and also considerably more expensive than corresponding exterior lights of non-watertight vehicles.
Es ist daher Aufgabe der Erfindung, die aus der
Diese Aufgabe ist erfindungsgemäß durch Außenleuchten mit den kennzeichnenden Merkmalen der Ansprüche 1 und 2 gelöst.This object is achieved by outdoor lighting with the characterizing features of claims 1 and 2.
Vorteilhafte Weiterbildungen dieser Lösung sind in den abhängigen Unteransprüchen gekennzeichnet.Advantageous developments of this solution are characterized in the dependent subclaims.
In der Beschreibung ist die erfindungsgemäße Ausgestaltung eines Hauptscheinwerfers beschrieben und in der Zeichnung dargestellt. Die Ausgestaltung gilt sinngemäß für weitere Außenleuchten, wie z. B. Blinkleuchten, Rückleuchten, Mehrkammerschlussleuchten, Begrenzungsleuchten und dergleichen: Dadurch, dass erfindungsgemäß handelsübliche Außenleuchten von nichtwatfähigen Fahrzeugen verwendet, diese aber mit Druckluft beaufschlagt werden, sind diese Außenleuchten für den watfähigen Einsatz einsetzbar.In the description of the inventive design of a headlight is described and shown in the drawing. The design applies mutatis mutandis to other outdoor lights, such. As a result of the fact that according to the invention commercial outdoor lights used by non-wattfähigen vehicles, but these are acted upon with compressed air, these outdoor lights are used for the watfähige use.
Bei der Lösung gemäß Anspruch 1 wird Druckluft an einer Stelle der Außenleuchte in diese einspeist und an einer anderen Stelle derselben, z. B. gegenüberliegend, wieder abgeführt. in der Außenleuchte entsteht dabei ein leichter Überdruck. Vorzugsweise verwendet man getrocknete Druckluft nach einem Lufttrockner, der Bestandteil der bordinternen Druckluftversorgungsanlage ist.In the solution according to claim 1 compressed air is fed at one point of the outdoor light in this and at another point the same, z. B. opposite, again dissipated. in the outdoor light creates a slight overpressure. Preferably used dried compressed air after an air dryer, which is part of the onboard compressed air supply system.
Die Druckluftmenge, die durch die Außenleuchte strömt, ist relativ gering. Da der Systemdruck der Druckluft an Bord eines watfähigen Fahrzeuges im Normalfall etwa 10 bar und höher ist, muss sowohl der Druck wie auch die Druckluftmenge der Druckluftzufuhr „A” zur Außenleuchte entsprechend reduziert werden. Die hierfür notwendigen Ventile bzw. Geräte sind handelsüblich erhältlich und an geeigneten Stellen vorzusehen.The amount of compressed air flowing through the outdoor light is relatively low. Since the system pressure of the compressed air on board a watertight vehicle is normally about 10 bar and higher, both the pressure and the compressed air quantity of the compressed air supply "A" to the outdoor light must be reduced accordingly. The necessary valves or devices are commercially available and provided at appropriate locations.
Der Luftaustritt aus der Außenleuchte ist vorzugsweise mittels eines Schlauches durchzuführen. Dabei kann der Schlauch über die Wathöhe geführt und mit einem einfachen Druckbegrenzungsventil versehen sein. Es ist auch denkbar, dass man einen Schlauch mit sehr kleinem Innendurchmesser verwendet, so dass über die Schlauchlänge der gewünschte geringe Überdruck in der Außenleuchte entsteht, oder man setzt eine Blende oder eine Drossel am Ende der Luftaustrittsleitung ein, die eine kleine Ausströmbohrung aufweist, die ebenfalls die Druckluftmenge begrenzt und den Druckluftaufbau in der Außenleuchte sicherstellt. Durch die beschriebenen Maßnahmen dringt weder Wasser in die Außenleuchte ein noch kann sich Kondensat in deren Innenraum bilden. Etwaige nach einer längeren Standzeit des Fahrzeugs in den Außenleuchten gebildetes Kondensat wird durch die zugeführte Druckluft aus den Außenleuchte abgeführt.The air outlet from the outdoor light is preferably carried out by means of a hose. The hose can be guided over the wath height and provided with a simple pressure relief valve. It is also conceivable that one uses a tube with a very small inner diameter, so that over the hose length of the desired low pressure in the outdoor lamp is formed, or it uses a shutter or a throttle at the end of the air outlet pipe, which has a small outflow hole, the also limits the amount of compressed air and ensures the air pressure build-up in the outdoor light. Due to the measures described, neither water penetrates into the outdoor light nor can condensate form in its interior. Any condensate formed in the exterior lights after a longer service life of the vehicle is removed from the outdoor light by the supplied compressed air.
Bei der erfindungsgemäßen Lösung nach Anspruch 2 wird die Außenleuchte nur mit Druckluft beaufschlagt, so dass sie unter geringerem Überdruck steht und somit kein Wasser eindringen kann. Der Überdruck kann z. B. 0,10 bis 0,20 bar betragen. Bei der Ausführung nach Anspruch 2 ist ebenfalls eine Druckregelung der Druckluft vorzusehen. Eine Abfuhr des Kondensates durch durchströmende Luft ist hier nicht vorgesehen. Dafür ist die Ausgestaltung der erfindungsgemäßen Vorrichtung einfacher und billiger und kann z. B. bei einer Heckleuchte oder einer Mehrkammerschlussleuchte schon genügen.In the inventive solution according to claim 2, the outdoor lamp is acted upon only with compressed air, so that it is under lower pressure and thus no water can penetrate. The overpressure can z. B. 0.10 to 0.20 bar. In the embodiment according to claim 2, a pressure control of the compressed air is also provided. A removal of the condensate by air flowing through is not provided here. For the design of the device according to the invention is simpler and cheaper and can, for. B. at a tail light or a Mehrkammerschlussleuchte already enough.
Nachfolgend sind zwei Ausführungsbeispiele der Erfindung anhand der Zeichnung näher beschrieben.Below, two embodiments of the invention are described in more detail with reference to the drawing.
