Abstract
Description
Die Erfindung betrifft eine Signalanlage zur Montage auf dem Dach von Einsatzfahrzeugen, umfassend ein Gehäuse mit einem Deckenabschluss sowie Außenwände, die mit Öffnungen versehen sind, hinter denen sich Signalleuchten befinden. Die Erfindung bezieht sich auch auf ein Kraftfahrzeug mit einer solchen Signalanlage.The Invention relates to a signal system for mounting on the roof of Emergency vehicles, including a housing with a ceiling finish as well Exterior walls that with openings are provided, behind which there are signal lights. The invention also relates to a motor vehicle with such a signal system.
Derartige Signalanlagen für Einsatzfahrzeuge sind in zahlreichen Variationen bekannt. Es sei beispielsweise genannt die GB-Schrift 2 359 179 A. Hier ist ein balkenartiger Aufsatz auf das Fahrzeugdach mit Hilfe von Reitern befestigt. Der Aufsatz ist mit lumineszenzemittierenden Dioden (LEDs) bestückt und gibt Signalinformationen in an sich bekannter Art akustisch und optisch ab.such Signal systems for Emergency vehicles are known in numerous variations. For example called GB 2 359 179 A. Here is a beam-like essay attached to the vehicle roof with the help of riders. The essay is equipped with luminescence emitting diodes (LEDs) and gives signal information in a known manner acoustically and optically.
Bei dieser Art des Aufbaus ist nachteilig, dass gegen den Fahrtwind sich hohe Luftwiderstände ergeben, die letztendlich die Einsatzmöglichkeiten des Fahrzeuges einschränken, da sie die Höchstgeschwindigkeit begrenzen. Außerdem wird bei der hohen Kilometerleistung derartiger Einsatzfahrzeuge ein signifikanter Kraftstoff- Mehrverbrauch beobachtet. Die Aufbauten erzeugen außerdem ein nachteiliges Fahrverhalten.at This type of construction is disadvantageous against the headwind high air resistance result, which ultimately the possible uses of the vehicle restrict since it's the top speed limit. Moreover is at the high mileage of such emergency vehicles significant fuel consumption observed. The superstructures also produce disadvantageous driving behavior.
Es stellt sich damit die Aufgabe, eine Signalanlage anzugeben, die einen wesentlich geringeren Luftwiderstand hat, das Fahrverhalten kaum negativ beeinflusst und die damit sowohl die Einsatzmöglichkeiten als auch die Performance des Fahrzeuges, bei Ausstattung mit einer derartigen Signalanlage, optimiert.It the task thus arises of specifying a signal system which has a much lower air resistance, the driving behavior hardly negatively influenced and thus both the possible uses as well as the performance of the vehicle when equipped with a such signaling system, optimized.
Diese Aufgabe wird gelöst durch eine Signalanlage der eingangs genannten Art, bei der das Gehäuse als flache gewölbte Haube gestaltet ist, deren unterer Rand dicht auf das Fahrzeugdach auflegbar und ohne Zwischenträger mit dem Fahrzeugdach verbindbar ist, und bei dem die Leuchten wenigstens in Fahrtrichtung von lumineszenzemittierende Halbleiter-Dioden mit einem Lichtstrom von jeweils größer als 30 lm gebildet sind.This Task is solved by a signal system of the type mentioned, in which the casing as a flat arched Hood is designed, the lower edge of which is tight on the vehicle roof can be put on and without intermediate straps is connectable to the vehicle roof, and in which the lights at least in Direction of travel of luminescence-emitting semiconductor diodes a luminous flux of greater than 30 lm are formed.
Der für den Luftwiderstand wichtige cw-Wert der Signalanlage sollte gegen die Fahrtrichtung, also gegen den Fahrtwind bei Geradeausfahrt, unter 0,5, vorzugsweise zwischen 0,15 und 0,40 liegen. Dabei sollte die Bauhöhe des Gehäuses, vom Wagendach-Scheitel gemessen, maximal 300 mm betragen. Hierdurch wird der Luftwiderstand des Fahrzeuges insgesamt nicht wesentlich erhöht; er liegt bedeutend unter dem Wert, der bei bekannten kastenförmigen Aufbauten von Signalanlagen beobachtet wird.The c w value of the signaling system, which is important for air resistance, should be less than 0.5, preferably between 0.15 and 0.40, against the direction of travel, i.e. against the wind when driving straight ahead. The overall height of the housing, measured from the top of the car roof, should be a maximum of 300 mm. As a result, the overall air resistance of the vehicle is not significantly increased; it is significantly below the value observed in known box-shaped structures of signaling systems.
Weitere Merkmale gehen aus den Unteransprüchen hervor.Further Features emerge from the subclaims.
Die Erfindung mit den Merkmalen der Ansprüche wird anhand der Zeichnung erläutert.The Invention with the features of the claims is based on the drawing explained.

Um
den Luftwiderstand zu verringern, der durch Fahrzeug-Aufbauten wesentlich
erhöht
wird, ist das Gehäuse
Dabei ist:there is:
- FL = LuftwiderstandF L = air resistance
- cW = Luftwiderstandsbeiwertc W = coefficient of drag
- A = QuerschnittsflächeA = cross-sectional area
- ρ = Luftdichteρ = Airtight
- v = Anströmgeschwindigkeitv = flow velocity
Der cW-Wert ist etwa 1 bei einer flachen, angeströmten Platte. Im vorliegenden Fall ergibt sich ein cW-Wert für das Gehäuse allein von etwa 0,2. Bei kastenförmigen Aufbauten, wie sie üblicherweise für Signalanlagen verwendet werden, liegt der cw-Wert etwa bei 0,6 bis 0,9, so dass bei diesen Konstruktionen der gesamte Luftwiderstand des Fahrzeugs wesentlich erhöht ist. Daraus resultiert eine geringere Höchstgeschwindigkeit des Fahrzeugs, eine für Einsatzfahrzeuge entscheidende Größe.The c W value is about 1 for a flat, flowed plate. In the present case, the c W value for the housing alone is approximately 0.2. In box-type structures, as are usually used for signaling systems, the drag coefficient is approximately 0.6 to 0.9, so that the overall air resistance of the vehicle is significantly increased in these constructions. This results in a lower top speed of the vehicle, a crucial factor for emergency vehicles.
