Description

  

  Stromlinienförmiges Heckmotorfahrzeug mit vorn liegendem Kühllufteinlass.    Bei stromlinienförmigen Heckmotorfahr  zeugen herrscht an dem hintern Teil des  Fahrzeuges bei rascher Fahrt gewöhnlich ein  bedeutender Unterdruck. Deshalb bereitet es  grosse Schwierigkeiten, dem Motor eine ge  nügende Kühlluftmenge zuzuführen, auch  wenn dieser mit sehr wirksamen Gebläsen  ausgestattet ist. Es wurden schon vorn be  findliche Kühllufteintrittsöffnungen vorge  schlagen, von denen aus die Luft durch  Kanäle dem im Heck befindlichen Motor  zugeführt wird. Je höher die Temperatur der  Aussenluft ist, umsomehr Kühlluft muss zu  geführt werden, was jedoch bei geschlossenen  Stromlinienkarosserien nicht durch einfache  Mittel, z. B.     durch.    blosse Vergrösserung der       Öffnungen,    erzielt werden kann.  



  Gemäss der Erfindung wird ein Teil der  Kühlluft unmittelbar durch das Innere der  Karosserie hindurchgeführt.  



  Vorteilhaft wird die Kühlluft vom Vorder  teil des Fahrzeuges, an welchem bei rascher  Fahrt ein bedeutender     Überdruck    herrscht,    durch     Öffnungen    und Kanäle zur Vorderwand  des     Karosserieinnenraumes    geführt, wo sie  durch mittels Klappen regelbare Öffnungen  in den Fahrgastraum eintritt, um an den  Sitzen vorbei den in der Rückwand des  Raumes angeordneten Öffnungen und von  diesen dem     Motorraum    zuzuströmen.     Diese     Ausbildung hat den Vorteil, dass die Kühl  luft durch den Innenraum der Karosserie  streicht, ohne dass dadurch die Fahrgäste  behindert werden. Im Gegenteil wird eine  wirksame Belüftung des Innenraumes erzielt.  



  Auf der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes schema  tisch im Horizontalschnitt dargestellt.  



  Im Vorderteil 1 des Fahrzeuges sind An  saugöffnungen 2 und Kanäle 3 vorgesehen,  durch welche die Luft an der Innenseite- der  Kotflügel zu den Regelklappen 4 an der  Vorderwand des Fahrgastraumes geführt  wird. Seitlich an den Vordersitzen 5 sind  Leitwände 6 für die Luft und an den rück  wärtigen Sitzen 7 die Öffnungen 8 ver-      schliessende Regelklappen 9 vorgesehen, von  denen Kanäle 10 zu     Öffnungen    in der Rück  wand des     Fahrgastraumes    und weiter zum  Motorraum 11 im Heck der Karosserie  führen.  



  Statt ausserhalb der Sitze zwischen diesen  und den Karosserieseitenwänden bezw. den  Türen kann die Luft auch zwischen den  Sitzen geführt werden. Die Luftführung kann  zum Beispiel auch durch den Vorderteil des  Fahrzeuges erfolgen.  



  Im Motorraum wird die Luft durch Ge  bläse oder Ventilatoren angesaugt.



  Streamlined rear engine vehicle with cooling air intake at the front. In the case of streamlined rear-engined vehicles, there is usually a significant negative pressure at the rear of the vehicle when driving rapidly. It is therefore very difficult to supply a sufficient amount of cooling air to the engine, even if it is equipped with very effective fans. There were already front be sensitive cooling air inlets propose, from which the air is fed through ducts to the engine located in the rear. The higher the temperature of the outside air, the more cooling air has to be supplied, but this cannot be achieved by simple means in closed streamlined bodies, e.g. B. by. mere enlargement of the openings can be achieved.



  According to the invention, part of the cooling air is passed directly through the interior of the body.



  Advantageously, the cooling air from the front part of the vehicle, on which there is significant overpressure when driving fast, is passed through openings and channels to the front wall of the body interior, where it enters the passenger compartment through openings that can be regulated by means of flaps, in order to pass the seats in the Rear wall of the space arranged openings and flow from these to the engine compartment. This training has the advantage that the cooling air passes through the interior of the body without the passengers being hindered. On the contrary, effective ventilation of the interior is achieved.



  In the drawing, an embodiment example of the subject invention is shown schematically in horizontal section.



  In the front part 1 of the vehicle suction openings 2 and channels 3 are provided through which the air on the inside of the fenders is guided to the control flaps 4 on the front wall of the passenger compartment. At the side of the front seats 5 are baffles 6 for the air and on the rear seats 7 the openings 8 closing control flaps 9 are provided, of which channels 10 lead to openings in the rear wall of the passenger compartment and on to the engine compartment 11 in the rear of the body .



  Instead of outside the seats between these and the body side walls respectively. The doors can also be used to guide the air between the seats. The air can also be routed through the front part of the vehicle, for example.



  In the engine compartment, the air is drawn in by blowers or fans.
