Title (DE) KRAFTFAHRZEUG MIT ZUMINDEST ZWEI TANKS FÜR DIE AUFNAHME VON BRENNSTOFF UNTER HOHEM DRUCK
(EN) MOTOR VEHICLE WITH AT LEAST TWO TANKS FOR RECEIVING FUEL UNDER HIGH PRESSURE
(FR) VÉHICULE AUTOMOBILE COMPRENANT AU MOINS DEUX RÉSERVOIRS DESTINÉS À CONTENIR DU CARBURANT SOUS HAUTE PRESSION
Abstract:
(DE) Die Erfindung betrifft ein zweispuriges mehrachsiges Kraftfahrzeug mit zumindest zwei Brennstoff-Tanks (1, 2), in denen ein Brennstoff zur Erzeugung von Antriebsenergie für ein Fahrzeug-Antriebsaggregat unter hohem Druck in der Größenordnung von 300 bar und mehr speicherbar ist, wobei jeder Tank eine Sicherheitsventil-Einrichtung (13, 23) mit einem nur einen Teilbereich der Tank-Oberfläche überwachenden temperatursensitiven Element aufweist, welche auf höhere, beispielsweise bei einem Brand auftretende Temperaturen hin zumindest eine Teilmenge des gespeicherten Brennstoffs aus dem jeweiligen Tank entweichen lässt. Dabei sind die temperatursensitiven Elemente zumindest zweier Tanks solchermaßen angeordnet, dass sich der Abstand zwischen einem linksseitigen Rad (RL) derjenigen Fahrzeug-Achse, in deren Nähe die zumindest zwei Brennstoff-Tanks (1, 2) im Fahrzeug angeordnet sind, und dem diesem Rad nächstliegenden temperatursensitiven Element nicht signifikant vom Abstand des anderen dieser beiden temperatursensitiven Elemente vom rechtsseitigen Rad (RR) dieser Achse unterscheidet.
(EN) The invention relates to a two-track multi-axle motor vehicle with at least two fuel tanks (1, 2) in which a fuel for producing driving energy for a vehicle drive unit can be stored under high pressure of the order of magnitude of 300 bar and more, wherein each tank has a safety valve device (13, 23) with a temperature-sensitive element monitoring only a partial region of the tank surface, said safety valve device allowing at least a partial quantity of the stored fuel to escape from the respective tank at higher temperatures occurring, for example, in a fire. The temperature-sensitive elements of at least two tanks are arranged here in such a manner that the distance between a left-side wheel (RL) of that vehicle axle, in the vicinity of which the at least two fuel tanks (1, 2) are arranged in the vehicle, and the temperature-sensitive element closest to said wheel does not significantly differ from the distance of the other of said two temperature-sensitive elements from the right-side wheel (RR) of said axle.
(FR) L'invention concerne un véhicule automobile à deux voies à essieux multiples comprenant au moins deux réservoirs de carburant (1, 2), dans lesquels un carburant pour la génération d'énergie de propulsion pour un groupe motopropulseur de véhicule peut être stocké sous une haute pression de l'ordre de 300 bars et plus, chaque réservoir comprenant un dispositif formant soupape de sécurité (13, 23) doté d'un élément sensible à le température ne surveillant qu'une partie de la surface du réservoir, lequel dispositif laisse s'échapper, à des températures plus élevées se produisant par exemple lors d'un incendie, au moins une partie du carburant stocké hors du réservoir respectif. Selon l'invention, les éléments sensibles à la température d'au moins deux réservoirs sont disposés de telle sorte que la distance entre une roue (RL) côté gauche de l'essieu de véhicule à proximité duquel lesdits au moins deux réservoirs de carburant (1, 2) sont disposés dans le véhicule et l'élément sensible à la température le plus proche de cette roue n'est pas significativement différente de la distance entre l'autre de ces deux éléments sensibles à la température et la roue (RR) côté droit de cet essieu.
