Description
Einrichtung an Heckmotorfahrzeugen zur Zuführung von Luft zum Motorraum. Bei Kraftfahrzeugen: mit Heckmotor ist es schwierig, dem Motorraum :eine genügende Menge frischer Kühlluft zuzuführen. Bisher wurde die Kühlluft meist den bei der Fahrt an den Fahrzeugwänden entstehenden Luft strömen entnommen, und zwar entweder am Dach oder an den Seiten oberhalb der Hinter räder, wo Öffnungen und Kanäle angeord net sind, die die Luft in das Innere des Fahrzeuges führen.
Wenn :die Kühlluft durch Öffnungen von oben zugeführt wird, so hat das den Nachteil, dass der auf der Oberseite des Fahrzeuges, insbesondere an dessen, hinterem Teil während der Fahrt ge wöhnlich herrschende, ziemlich grosse Unter druck dem Eindringender Luft in das Innere des Fahrzeuges entgegenwirkt.
Bei den seit lichen Ansaugöffnungen: ergibt sich wie- derum die Schwierigkeit, dass für diese Öff- nungen, verhältnismässig wenig Platz zur Verfügung steht.
Gemäss der Erfindung soll bei mindestens einer Zufuhröffnung eine viel bessere und wirksamere Kühlung .dadurch erreicht wer den, dass die Öffnung für :die Kühlluftzu fuhr und der von dieser zum Motarraum führende Kanal. an der Unterseite ,des Fahr zeuges unter den hintern Sitzen vor der Hin terachse angeordnet und über .die ganze Breite des Fahrzeugbodens ausgedehnt ist.
Hier herrscht während :der Fahrt :ein ziem lich grosser. Überdruck, der ein starkes Ein dringen der Luft in den Motorraum des Fahrzeuges begünstigt, wobei .der Zufuhr kanal an :dieser Stelle die leichte Zugäng lichkeit der verschiedenen Motorteile nicht zu behindern braucht.
Der unter den hintern :Sitzen; befindliche Raum wurde bisher hauptsächlich zum La gern von Werkzeugen und ähnlichem ver wendet, was unpraktisch ist. Im Bedarfs falle ist es nämlich notwendig, dass die auf den Sitzen befindlichen Personen aussteigen, und so geschieht es, .dass die Werkzeuge und notwendigen Ersatzteile stets lieber ander- wärts gelagert werden, und dieser freie un- benützte Raum wird .dann zur Ablagerungs stätte verschiedener wenig gebrauchter Ge genstände, die darin gewöhnlich verrosten, beschlagen oder sonstwie verderben.
Die Ausnützung dieses Raumes für die Kühlluftzufuhr beseitigt also- gleichzeitig auch diesen bei den meisten Fahrzeugen der beschriebenen Bauart gewöhnlich auftreten den Übelstand.
Ein Ausführungsbeispiel des Erfin- dungsgegenstandes ist in der Zeichnung sche matisch im Längsschnitt dargestellt.
Der Wagenkasten 1 hat hinten einen ab geteilten Raum 2, in dem der Fahrzeug motor bezw. das ganze Antriebsaggregat un tergebracht ist. Unter den hintern Sitzen 3 ist vor der Hinterachse ein nach unten offe ner Kanal 4 für die Zufuhr der Kühlluft an gebracht, .die in diesen in der .durch einen Pfeil angedeuteten Richtung eintritt. Der Kanal ist dabei über die ganze Breite des Fahrzeugbodens ausgedehnt, um den Luft eintritt zu erleichtern.
Device on rear-engined vehicles for supplying air to the engine compartment. In motor vehicles: with a rear-engined engine, it is difficult to supply the engine compartment with a sufficient amount of fresh cooling air. So far, the cooling air has mostly been taken from the air flowing on the vehicle walls when driving, either on the roof or on the sides above the rear wheels, where openings and channels are net angeord that lead the air into the interior of the vehicle.
If: the cooling air is supplied through openings from above, this has the disadvantage that the rather high negative pressure that usually prevails on the top of the vehicle, especially on its rear part while driving, allows air to penetrate into the interior of the vehicle counteracts.
With the side suction openings: there is again the difficulty that there is relatively little space available for these openings.
According to the invention, with at least one supply opening, a much better and more effective cooling is to be achieved in that the opening for: the cooling air supply and the duct leading from this to the engine compartment. on the underside of the vehicle under the rear seats in front of the rear axle and extends over the entire width of the vehicle floor.
The rule here is during: the journey: quite a big one. Overpressure, which favors a strong penetration of air into the engine compartment of the vehicle, whereby .the supply channel at: this point does not need to hinder the easy accessibility of the various engine parts.
The one under the buttocks: sitting; The space available has so far been mainly used to store tools and the like, which is impractical. If necessary, it is necessary for the people in the seats to get out, and so it happens that the tools and necessary spare parts are always stored elsewhere, and this free, unused space then becomes a storage site Various little-used objects that usually rust, steam up or otherwise spoil in them.
The use of this space for the supply of cooling air thus eliminates - at the same time, these usually occur in most vehicles of the type described, the problem.
An embodiment of the subject of the invention is shown schematically in the drawing in longitudinal section.
The car body 1 has a rear from a divided space 2, in which the vehicle engine BEZW. the entire drive unit is housed. Under the rear seats 3 in front of the rear axle there is a downwardly open channel 4 for the supply of cooling air, which enters this in the direction indicated by an arrow. The channel is extended over the entire width of the vehicle floor in order to facilitate the entry of air.
