Description

  

  Stromlinienförmiges Fahrzeug mit Heckmotor.    Bei stromlinienförmigen Fahrzeugen mit  Heckmotor bietet die richtige Kühlung des  Motors eine     Hauptschwierigkeit.        Insbesondere     bei luftgekühlten Heckmotoren     wird    die       Kühlung        vorteilhaft    dadurch     unterstützt,     dass man nicht nur die Wände     und,den    Kopf  der Zylinder,     sondern    auch das Öl ,des Mo  tors in besonderen, dem     Kühlluftstrom        guss-          gesetzten    Kühlern kühlt.

   Dabei     tritt    aller  dings eine Schwierigkeit auf: In unmittel  barer Nähe des Motors     angeordnete        Ölküh-          ler    verbrauchen für     ihre        eigene    Kühlung  eine     bedeutende    Menge .der Kühlluft, die  ohnedies schon mit grossen Schwierigkeiten  dem     Motorraum        zugeführt    wird. Die für die       Kühlung    des     Öls        verbrauchte    Luft     isst    aber  für die Kühlung der     Motorzylinder    und ihrer  Köpfe ungeeignet.  



  Gemäss der     Erfindung    ist diese Schwie  rigkeit dadurch behoben, dass der Ölkühler  vorn im     Fahrzeug    angeordnet und mit -dem       im,        Heak        angeordneten    Motor durch Umlauf-         leitengen    verbunden ist.     Zweckmässig    ist der       Auslass,der    Kühlluft     für,diesen    Kühler noch  am Vorderteil des Fahrzeuges angeordnet,  während sich der Einlass für die Luft zur  Kühlung     es    Motors am     rückwärtigen    Teil  des Fahrzeuges befindet.

       Es    können Vorkeh  ren getroffen sein, um im     Winter    die durch  den Ölkühler erwärmte     frische    Luft zum  Heizen des     Wageninnern        verwenden    zu  können.  



  Ein     Ausführungsbeispiel    des     Erfindungs-          gegenstandes    ist in der Zeichnung durch  eine perspektivische Ansicht des Fahrzeug  vorderteils schematisch veranschaulicht.  



  Im     Vorderteil    der Karosserie 1 des strom  linienförmig gebauten Wagens ist der     ein-          oder        mehrteilige    Kühler 2 für     das        Öl    ange  ordnet, zu welchem die Luft durch die Öff  nungen d Zutritt hat. Vom Kühler, der  durch     Umlaufleitungen    mit dem Heckmotor       verbunden    ist, führen zu beiden Seiten  Kanäle 4 nach hinten, durch welche die er-      wärmte Luft     entweder    nach aussen entweicht,  oder nach Verstellung der Regelklappen 5  in den Fahrgastraum eintritt und diesen  beheizt.  



  Die Auslassöffnungen 6 der Ableitungs  hanäle sind zweckmässig an der Oberfläche  des     Karosserievorderteils    angeordnet, damit  die erwärmte Luft während der Fahrt nicht  in den Bereich der Öffnungen am rückwär  tigen Karosserieteil gelangt, durch welche  frische Luft in den Motorraum für die Küh  lung des Motors eintritt und welche sich in  der Regel im Dach des     obern    Karosserieauf  satzes befinden.



  Streamlined vehicle with a rear engine. On streamlined rear-engined vehicles, properly cooling the engine is a major difficulty. In the case of air-cooled rear-mounted engines in particular, cooling is advantageously supported by not only cooling the walls and the cylinder head, but also the oil of the engine in special coolers that are cast in the cooling air flow.

   However, one difficulty arises here: oil coolers arranged in the immediate vicinity of the engine consume a significant amount of cooling air for their own cooling, which is already supplied to the engine compartment with great difficulty. The air used to cool the oil is unsuitable for cooling the engine cylinders and their heads.



  According to the invention, this difficulty is eliminated in that the oil cooler is arranged in the front of the vehicle and is connected to the engine arranged in the heak by circulating ducts. The outlet for the cooling air for this radiator is expediently arranged on the front part of the vehicle, while the inlet for the air for cooling the engine is located on the rear part of the vehicle.

       Provisions can be made to use the fresh air warmed by the oil cooler to heat the interior of the car in winter.



  An embodiment of the subject matter of the invention is schematically illustrated in the drawing by a perspective view of the vehicle front part.



  In the front part of the body 1 of the streamlined car, the one-piece or multi-part cooler 2 is arranged for the oil, to which the air has access through the openings d. From the cooler, which is connected to the rear engine by circulation lines, ducts 4 lead to the rear on both sides, through which the heated air either escapes to the outside or, after adjusting the control flaps 5, enters the passenger compartment and heats it.



  The outlet openings 6 of the discharge channels are conveniently arranged on the surface of the front body part so that the heated air does not get into the area of the openings on the rear body part through which fresh air enters the engine compartment for cooling the engine while driving and which are usually in the roof of the upper body attachment.
