Description

  

  Einrichtung an Fahrzeugen mit Heckmotor zur Kühlung desselben  durch ein Achsialgebläse.    Bei Fahrzeugen mit Heckmotor wird die  Kühlluft in den Motorraum vielfach durch  oberhalb des Motors vor diesem etwa zwi  schen dem Ende des Daches der eigentlichen  Karosserie und dem     vordern    Rand des Mo  tordeckels befindliche Schlitze zugeführt,  wobei die Gebläse so angeordnet sind, dass  die Kühlluft mehrere Male die Richtung  ändern muss, was stets einen Widerstand und  dadurch eine Verschlechterung der Kühlwir  kung der Luft bedeutet. Aus diesem Grunde  ist es vorteilhaft, für die Zuführung der  Kühlluft Achsialgebläse zu benutzen, weil  diese die Richtung des Luftstromes fast gar  nicht ändern, während ein Radialgebläse die  Richtung der Luft direkt im rechten     Winkel     ändert.  



  Gemäss der Erfindung ist bei Verwen  dung eines Achsialgebläses dieses in der  Längsrichtung eines Luftleitkanals angeord  net, der die Luft von den Eintrittsschlitzen    oberhalb des Motors vor diesem schräg nach  unten zu Luftaustrittslöchern unter dem  Motor führt. Vorteilhaft wird die schräg ge  lagerte Gebläsewelle durch ein Kegelgetriebe  von der Kurbelwelle des Motors angetrieben.  



  In der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes schema  tisch im     Schnitt    durch den rückwärtigen  Karosserieteil eines stromlinienförmigen  Fahrzeuges mit Heckmotor veranschaulicht.  



  Im rückwärtigen Teil 1 der stromlinien  förmigen Karosserie 2 des Fahrzeuges ist  der Motor     ä    mit dem Antrieb 4 der     hintern     Achsen und dem Schaltgetriebe 5 angeord  net. Der Motordeckel 6 ist     aufklappbar.    Zwi  schen seiner obern Kante 7 und dem Ende 8  des Daches der eigentlichen Karosserie be  steht vor dem Motor ein Schlitz, durch wel  chen die Luft in den     Motorraum    eindringt.  



  In dem schrägen     Luftleitkanal   <B>13</B> zwi  schen dem Eintrittsschlitz und Öffnungen 14      unter dem Motor ist ein Achsialgebläse 9 in  dessen Längsrichtung angeordnet, dessen  Welle 10 schräg nach unten zum Motor  führt, wo sie durch das Kegelgetriebe 11 an  getrieben wird.  



  Der Pfeil 12 gibt die Richtung des Luft  stromes an. Es ist ersichtlich, dass an Stelle  des veranschaulichten vierzylindrigen Mo  tors mit in waagrechter Ebene angeordneten  Zylindern ein achtzylindriger Motor mit in  V-Form angeordneten Zylindern Verwendung  finden kann, wobei der Luftstrom in den  Raum zwischen diesen Zylindern eindringt  und an den     Kühlrippen    vorbei nach unten  strömt, um ebenso wie bei der veranschau  lichten     Ausführung    unterhalb des Motors  nach aussen zu gelangen.



  Device on vehicles with a rear engine for cooling the same by an axial fan. In vehicles with rear-mounted engines, the cooling air is often fed into the engine compartment through slots located above the engine in front of it, roughly between the end of the roof of the actual body and the front edge of the engine cover, the fans being arranged so that the cooling air is released several times has to change direction, which always means resistance and thus a deterioration in the cooling effect of the air. For this reason, it is advantageous to use axial fans to supply the cooling air, because they hardly change the direction of the air flow at all, while a radial fan changes the direction of the air directly at a right angle.



  According to the invention, when using an axial fan, this is angeord net in the longitudinal direction of an air duct, which leads the air from the inlet slots above the motor obliquely downwards to air outlet holes below the motor. The obliquely mounted fan shaft is advantageously driven by a bevel gear from the crankshaft of the engine.



  In the drawing, an embodiment example of the subject invention is schematically illustrated in section through the rear body part of a streamlined vehicle with a rear engine.



  In the rear part 1 of the streamlined body 2 of the vehicle, the motor - with the drive 4 of the rear axles and the gearbox 5 is angeord net. The motor cover 6 can be opened. Between tween its upper edge 7 and the end 8 of the roof of the actual body be in front of the engine is a slot through which the air penetrates into the engine compartment.



  In the inclined air duct <B> 13 </B> between the inlet slot and openings 14 under the motor, an axial fan 9 is arranged in its longitudinal direction, the shaft 10 of which leads obliquely down to the motor, where it is driven by the bevel gear 11 .



  The arrow 12 indicates the direction of the air flow. It can be seen that instead of the illustrated four-cylinder motor with cylinders arranged in a horizontal plane, an eight-cylinder motor with cylinders arranged in a V shape can be used, the air flow penetrating the space between these cylinders and flowing down past the cooling fins to get to the outside just like in the illustrated version below the engine.
