Description

       

  Kühlluftzuführungseinrichtung an stromlinienförmigen Fahrzeugen mit Heckmotor.    Die     Schwierigkeiten    bei der Zuführung  :der Kühlluft an stromlinienförmigen Fahr  eugen mit Heckmotor sind bekannt. Die  zeugen mit Heckmotor sind bekannt. Die       Unterbringung    des     Motors    im Heck des Fahr  zeuges hat zur Folge,     dass    die Zuführung  der Kühlluft vom Vorderende des Fahrzeuges  erschwert ist, da die zugehörigen Führungs  kanäle sonst zuviel Raum in der eigentlichen  Karosserie einnehmen.

   Aus diesem Grunde  wird die Kühlluft gewöhnlich erst hinter :dem       eigentlichen        Nutzraum    der Karosserie ange  saugt, wo     aber        während:    der Fahrt sauf der  obern Rückwand :der Karosserie und auch zu.  beiden     Seiten,des    Fahrzeuges durch die Luft  strümung     ein        Unterdruck        am    :den Karosserie  wänden     hervorgerufen    wird, der     direkt    gegen  :das Eindringender Kühlluft in die zugehöri  gen     Öffnungen        wirkt.     



  Die     einzige        Stelle,    wo auch beim Heck  ein Überdruck an, der Karosserieoberfläche  herrscht, isst ihre Unterseite, und es wurde  deshalb schon vorgeschlagen, die Eintritts-    öffnungen für die Kühlduft an der     Unter-          seite    der Karosserie, z.

   B. unter     :den    rück  wärtigen Sitzen,     anzubringen.    An der     Unter-          steite    der     Karosserie        kann    auch     .die    ganze  Breite     :des        Fahrzeuges    ausgenützt werden,  so dass die über die ,ganze Breite ausgeführ  ten Zuführungen imstande sind, eine genü  gende Kühlluftmenge zu liefern.

   Der einzige  Nachteil dieser Anordnung ist :der Umstand,  dass bei Regen und bei kotigem Terrain die       Fahrzeugräder    Wasser     verspritzen    und Ver  unreinigungen in diese Öffnungen eindringen  und durch sie in den Motorraum gelangen  können.  



  Die     Erfindung    bezweckt,     diesen    Übel  stand dadurch zu beseitigen, dass :die Öffnun  gen,     durch        welche    ,die Kühlduft von aussen in  .die Karosserie eindringt, in lotrechten, :der  Fahrzeuglängsmittelebene zugekehrten Flä  chen von Vorsprüngen .an der flachen     Ka-          rossierieunterseite    angebracht sind, wobei für       .die        in        diese        Öffnungen        eintretende    Luft Füh-      rungsflächen vorgesehen sind, -die in :

  einem  Bogen von der Längsmittelebene dress Fahr  zeuges zu     diesen        Öffnungen    verlaufen.  



  Die beigefügte     Zeichnung        zeigt        Schema-          ,buch:    ein Ausführungsbeispiel des Erfin  dungsgegenstandes in perspektivischer     An-          isicht    auf     ,das    Fahrzeug von unten.  



  An: der flachen Unterseite 1 des Fahr  zeuges     sind    zu Meiden     Seiten    dicht vor den       Hinterrädern    2 hohle Vorsprünge 3 angeord  net, deren der Längsmittelebene des Fahr  zeuges     zugekehrte        Flächen    4     mit        Öffnun-          gen    5     versehen    sind, durch, welche die Luft  in das Inneine dem Karosserie zum Heckmotor  raum dringt. Von :der Längsmittelebene des  Fahrzeuges laufen zu diesen Vorsprüngen 3  im Bogen angeordnete Führungsflächen 6,  damit die unter dem Fahrzeug während der  Fahrt komprimierte Luft in die Öffnungen 5  gelenkt wird.

   Vorteilhaft werden die Vor  sprünge 3 und die Flächen 6     mit    dem Blech  bodlen des Fahrzeuges aus einem Stück ge  presst, wodurch dieser Boden gut versteift       wird.     



  Es     isst        klar,    dass die Öffnungen 5 vollkom  men ausserhalb der     Richtung    des durch die       Wagenrüder        verspritzten    Wassers und     Kotes          angebracht    sind und     dass,    .durch die Fahrt         unter    dein Fahrzeug ein bedeutender Luft  druck erzielt     wird,    wodurch die Luft durch  die Öffnungen 5 in den Motorraum gepresst  wird, was dem Motorgebläse die Arbeit er-



  Cooling air supply device on streamlined vehicles with a rear engine. The difficulties with the supply: the cooling air on streamlined driving eugen with rear engine are known. The rear-engined witnesses are known. The accommodation of the engine in the rear of the vehicle has the consequence that the supply of cooling air from the front end of the vehicle is more difficult, since the associated guide channels otherwise take up too much space in the actual body.

   For this reason, the cooling air is usually only sucked in behind: the actual usable space of the body, but where: during the journey it s on the upper rear wall: the body and also closed. Both sides of the vehicle, the air flow creates a negative pressure on the body walls, which acts directly against: the penetration of cooling air into the associated openings.



  The only point where there is overpressure on the body surface at the rear is its underside, and it has therefore already been proposed to open the inlet openings for the cooling fragrance on the underside of the body, e.g.

   B. under: the back wärtigen seats to attach. The entire width of the vehicle can also be used on the underside of the body so that the inlets made over the entire width are able to deliver a sufficient quantity of cooling air.

   The only disadvantage of this arrangement is the fact that when it rains and on muddy terrain, the vehicle wheels splash water and contaminants can penetrate into these openings and get through them into the engine compartment.



  The aim of the invention is to eliminate this problem in that: the openings through which the cooling fragrance penetrates from the outside into .the body, in vertical,: the vehicle longitudinal center plane facing areas of projections are attached to the flat underside of the body , whereby guide surfaces are provided for the air entering these openings, -the in:

  an arc from the longitudinal center plane dress vehicle to these openings.



  The accompanying drawing shows a schematic, book: an embodiment of the subject of the invention in perspective view, the vehicle from below.



  On: the flat underside 1 of the vehicle are to avoid sides close to the rear wheels 2 hollow projections 3 angeord net, whose surfaces 4 facing the longitudinal center plane of the vehicle are provided with openings 5 through which the air in the interior Body penetrates to the rear engine compartment. From: the longitudinal center plane of the vehicle, guide surfaces 6 arranged in an arc run to these projections 3 so that the air compressed under the vehicle during travel is directed into the openings 5.

   Advantageously, the front jumps 3 and the surfaces 6 with the sheet metal bodlen of the vehicle are pressed in one piece ge, whereby this floor is well stiffened.



  It is clear that the openings 5 are placed completely outside the direction of the water and manure sprayed by the carriages and that a significant air pressure is achieved by driving under your vehicle, whereby the air through the openings 5 into the engine compartment is pressed, which makes the motor fan work
