Abstract
Description
Die Erfindung bezieht sich auf eine Verliersicherung für einen einen Einfüllstutzen abschließenden Tankdeckel.The invention relates to a Loss protection for a filler neck final Gas cap.
Üblicherweise erfolgt die Anbringung der Verliersicherung, insbesondere des Verbindungselementes, auch als Fang- oder Halteband bekannt, an der Fahrzeugkarosserie bzw. den naheliegenden Blech- oder Kunststoffteilen.Usually the attachment of the captive, in particular the connecting element, Also known as catch or tether on the vehicle body or the nearby sheet metal or plastic parts.
Aus der
Der Erfindung liegt als technisches Problem die Bereitstellung einer Verliersicherung der eingangs genannten Art zugrunde, die mit vergleichsweise geringem technischen Aufwand realisierbar ist und dabei an jedem freistehenden Einfüllstutzen unabhängig vom Fahrzeugtyp nachrüstbar ist.The invention is technical Problem providing a captive of the aforementioned Type based, with relatively little technical effort can be realized and at each freestanding filler neck independently Can be retrofitted to the vehicle type is.
Die Erfindung löst dieses Problem durch die Bereitstellung einer Verliersicherung mit den Merkmalen des Anspruchs 1. Die erfindungsgemäße Verliersicherung weist eine ringförmige, den Einfüllstutzen umschließbare Schelle mit einem Halter mit mindestens einer lochartigen Öffnung auf, über die das Verbindungselement mit der Schelle verbindbar ist.The invention solves this problem by providing a captive with the features of claim 1. The inventive captive has an annular, the filler neck umschließbare Clamp with a holder with at least one hole-like opening over the the connecting element is connectable to the clamp.
In einer Weiterbildung nach Anspruch 2 ist das Verbindungselement mittels eines Verschlusselementes am Halter befestigt.In a development according to claim 2 is the connecting element by means of a closure element on Holder attached.
Des Weiteren ist die Schelle gemäß Anspruch 4 unterhalb der Oberkante des Einfüllstutzens befestigbar oder verklemmbar. Der jeweilige Ort der Anbringung, d.h. der Abstand von der Oberkante des Einfüllstutzens, wobei als Oberkante die Auflagefläche des Tankdeckels bezeichnet wird, ist abhängig von der Länge des Verbindungselementes. Vorteilhaft ist hierbei die relativ einfache und unaufwendige Anbringung der Verliersicherung auf freistehende Einfüllstutzen. Die Nachrüstbarkeit unabhängig vom Fahrzeugtyp und von der Ausgestaltung des jeweiligen Einfüllstutzens erweist sich ebenfalls als Vorteil, die Entwicklungszeit und Kosten spart, da nicht konstruktiv vorgehalten werden muss.Furthermore, the clamp is according to claim 4 below the upper edge of the filler neck attachable or clamped. The particular location of attachment, i. the distance from the top of the filler neck, wherein referred to as the upper edge of the bearing surface of the tank lid will depend on the length of the connecting element. The advantage here is the relatively simple and uncomplicated attachment of the captive on freestanding filler neck. The retrofittability independently the type of vehicle and the design of the respective filler neck also proves to be an advantage, the development time and costs saves, because it does not have to be kept constructive.
Die zunehmende Verwendung von Kunststoffen im Automobilbau, insbesondere auch im Bereich der Kraftstoffzuführung, bergen den Nachteil, dass das Risiko einer elektrostatischen Aufladung, Entladung, Zündung und Verpuffung eines kritisch aufgeladenen Gas-Luft-Gemisches bei der Betankung nicht gänzlich auszuschließen ist, da sich Kunststoffe als elektrisch nicht leitende Werkstoffe infolge Reibung elektrisch aufladen.The increasing use of plastics in the automotive industry, especially in the field of fuel supply, salvage the disadvantage that the risk of electrostatic charge, discharge, ignition and deflagration of a critically charged gas-air mixture refueling not entirely excluded is because plastics are considered electrically non-conductive materials electrically charged due to friction.
Die Höhe der jeweiligen Aufladung hängt vom jeweiligen Kunststoff ab. wegen der geringen Leitfähigkeit der Kunststoffe fließen die Ladungen nur langsam zur Erde ab. Die Ursache der elektrostatischen Potentialaufladung kann unter anderem in der Bewegung des Treibstoffes innerhalb des Kunststofftanks, der Strömungsbewegung des Gasrückführstromes und des Kraft stoffstromes bei der Betankung, der vorausgegangenen Bewegung des Kraftfahrzeugs selbst oder in der Potentialübertragung durch die, die Betankung durchführende Person, liegen. Trotz antistatischer Ausrüstung der Kunststoffe muss das Restrisiko einer möglichen Aufladung durch geeignete technische Maßnahmen eliminiert werden, wie auch in der EG-Richtlinie 70/221 EWG gefordert. Um den gesetzlichen Vorgaben zu entsprechen, ist gemäß einer vorteilhaften Weiterbildung der Erfindung nach Anspruch 3 an einer weiteren lochartigen Öffnung des Halters eine Einrichtung zum Ableiten elektrostatischer Aufladungen angebracht.The amount of each charge depends on respective plastic. because of the low conductivity the plastics flow the charges only slowly to the earth. The cause of the electrostatic Potential charging can, among other things, in the movement of the fuel within the plastic tank, the flow movement of the gas recycle stream and the fuel flow during refueling, the previous one Movement of the motor vehicle itself or in the potential transmission through the ones performing the refueling Person, lying. Despite the antistatic finish of the plastics must the residual risk of a possible Charging be eliminated by appropriate technical measures, as required by EC Directive 70/221 EEC. To the legal To comply with specifications is according to a advantageous development of the invention according to claim 3 to a another hole-like opening the holder a device for dissipating electrostatic charges appropriate.
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind Gegenstand der Unteransprüche und der Beschreibung.Advantageous embodiments of Device according to the invention are the subject of the dependent claims and the description.
Die Erfindung wird anhand der beigefügten Zeichnung weiter beschrieben. Dabei zeigt in schematisch vereinfachter Darstellung beispielhaft:The invention will be apparent from the accompanying drawings further described. It shows in a simplified schematic representation example:
