Abstract

The invention relates to a fuel indicator, in particular for motor vehicles, with a pointer (2) which as main pointer indicates the amount of fuel contained in the fuel tank by means of a specific deflection angle of the pointer. According to the invention in addition to this main pointer (2), a second pointer (2) is provided as reserve fuel pointer for the amount of reserve fuel present. The reserve fuel pointer (1) also has a large degree of deflection in accordance with the deflection angle of the main pointer (2) so that the amount of reserve fuel still available can be read off precisely and clearly from the fuel indicator. In one embodiment of the invention, the main pointer (2) and the reserve fuel indicator (1) are to be driven by two separate coils, the resistance of the corresponding detector in the fuel tank being suitably adjusted for the given degrees of deflection of the pointers. <IMAGE>

Description

Die Erfindung betrifft eine Kraftstoffanzeige, insbesondere für Kraftfahrzeuge, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fuel gauge, in particular for motor vehicles, according to the preamble of claim 1.

Stand der TechnikState of the art

Die Kraftstoffanzeige ist meist sehr klein ausgeführt, somit ergibt sich eine Skaleneinteilung, die für die Reserveanzeige sehr kurz ist. Beim VW Polo ist die Reserveanzeige etwa 1/12 des gesamten Anzeigewinkels. Man kann deshalb nur ungenau ab­ lesen.The fuel gauge is usually very small, so there is a scale division for the reserve display is very short. The reserve display for the VW Polo is about 1/12 of the entire display angle. One can therefore only inaccurately read.

Beschreibung der ErfindungDescription of the invention

Solange der Kraftstofftank leer ist, sind beide Zeiger (1, 2) in der linken Skalenseite (Fig. 1). Wird der Kraftstofftank gefüllt, wandert zuerst der Reserveanzeiger (1) nach rechts und zeigt am Ende der Skala die vorgesehene Reservemenge an (beim Zeichnungsbeispiel 8 Ltr.) (Fig. 2). Nach weiterem Füllen des Kraftstofftanks bewegt sich der Hauptzeiger (2) nach rechts, bis er in der Endposition neben dem Reservezei­ ger zu stehen kommt. Durch Entnahme von Kraftstoff durch den Motor bewegt sich der Hauptzeiger (2) nach links, wie heute üblich. Nachdem dieser Zeiger bei weiterer Kraftstoffentnahme die linke Endposition erreicht hat (Fig. 3), fängt der Reser­ vezeiger (1) an, die vorgesehene Menge über den gesamten Be­ reich anzuzeigen (Fig. 3).As long as the fuel tank is empty, both pointers ( 1 , 2 ) are on the left side of the scale ( Fig. 1). If the fuel tank is filled, the reserve indicator ( 1 ) first moves to the right and shows the intended reserve quantity at the end of the scale (8 liters in the drawing example) ( Fig. 2). After filling the fuel tank further, the main pointer ( 2 ) moves to the right until it comes to a standstill next to the reserve pointer. When the engine draws fuel, the main pointer ( 2 ) moves to the left, as is common today. After this pointer has reached the left end position with further fuel removal ( Fig. 3), the reserve vezeiger ( 1 ) begins to display the intended amount over the entire loading range ( Fig. 3).

Claims (2)

1. Kraftstoffanzeige, insbesondere für Kraftfahrzeuge, dadurch gekennzeichnet, daß zwei Zeiger (1, 2), vorzugsweise auf derselben Achse, angeordnet sind, wobei der erste Zeiger (1) die Reserve­ menge und der zweite Zeiger (2) die gesamte Füllmenge anzeigt und beide Zeiger den gesamten Anzeigewinkel (α) beschreiben. (Fig. 1, 2, 3)1. Fuel gauge, in particular for motor vehicles, characterized in that two pointers ( 1 , 2 ), preferably on the same axis, are arranged, the first pointer ( 1 ) indicating the reserve quantity and the second pointer ( 2 ) indicating the total filling quantity and both pointers describe the entire display angle ( α ). ( Fig. 1, 2, 3) 2. Kraftstoffanzeige nach Anspruch 1, dadurch gekennzeichnet, daß die Zeiger durch zwei getrennte Spulen angetrieben wer­ den, wobei der Widerstand des Gebers im Tank entsprechend abgestimmt ist.2. Fuel gauge according to claim 1, characterized in that the hands are driven by two separate coils the, with the resistance of the sensor in the tank accordingly is coordinated.
