Description

Anordnung der Kühllufteinlaßschlitze in den Seitenwänden des Motorraumdeckels eines stromlinienförmigen Heckmotorfahrzeuges Die Erfindung bezieht sich auf eine Anordnung der Kühllufteintrittsschlitze in den Seitenwänden des Motorraumdeckels bei stromlinienförmigen Heckmotorfahrzeugen. Die Schwierigkeiten bei der Kühlluftzufuhr zum Motorraum stromlinienförmiger Fahrzeuge mit im Heck des Wagenkastens angeordneten luftgekühltem Motor sind bekannt. Bisher werden zu diesem Zwecke ariz Ende des. eigentlichen Wagenkastens oder am Anfang des Motorraumes an der oberen Fläche oder zu dessen beiden Seiten Öffnungen vorgesehen, die die den Wagenkasten während der Fahrt umströmende Luft auffangen und den Motorgebläsen im Motorraum zuführen. Häufig werden diese Offfnungen so ausgeführt, daß zum Erhöhen der Lüftungswirkung ihre Ränder in zum Luftstrom entgegengesetzter Richtung trichterförmig erweitert sind. Diese vorstehenden Ränder der Eintrittsöffnungen beeinträchtigen aber die richtige Stromlinienform des Wagenkastens.Arrangement of the cooling air inlet slots in the side walls of the engine compartment cover of a streamlined rear engine vehicle The invention relates to a Arrangement of the cooling air inlet slots in the side walls of the engine compartment lid in streamlined rear-engined vehicles. The difficulties with the cooling air supply to the engine compartment of streamlined vehicles with arranged in the rear of the car body air-cooled engines are known. So far, for this purpose ariz the end of the. actual car body or at the beginning of the engine compartment on the upper surface or on both sides of which openings are provided, which the car body during the Catch air flowing around the vehicle and feed it to the engine fan in the engine compartment. Frequently these openings are carried out so that to increase the ventilation effect Edges are widened funnel-shaped in the opposite direction to the air flow. However, these protruding edges of the inlet openings impair the correct one Streamlined shape of the car body.

Es ist auch bereits bekannt, waagerechte Schlitze in Richtung der Luftströmung anzuordnen. In diese kann jedoch Luft nur dann eintreten, wenn außen ein Überdruck bzw. innen ein entsprechender Unterdruck herrscht. Ferner ist es nicht neu, vor dem hinteren Kotflügel nach hinten geneigte, mit Abdeckstreifen versehene Schlitze anzuordnen. Hier wird jedoch die Luft an der Vorderseite des Kotflügels nach oben abgelenkt, so daß sie etwa senkrecht zu den Schlitzen strömt und die Fangschaufeln der einzelnen Schlitze jeweils im Windschatten der in Strömungsrichtung davorIleggenden Fangschaufel bzw. Fangschaufeln liegen.It is also already known to have horizontal slots in the direction of the Arrange air flow. However, air can only enter this when outside an overpressure or a corresponding negative pressure prevails inside. Further it is not new, inclined backwards in front of the rear fender, provided with cover strips To arrange slots. Here, however, the air is at the front of the fender deflected upwards so that it flows approximately perpendicular to the slots and the catch blades of the individual slots in the slipstream of the one in front of it in the direction of flow The catch shovel or shovels lie.

Gemäß der Erfindung wird die Luftzufuhr in den Motorraum dadurch erzielt, daß in den Seitenwänden des Motorraumdeckels Schlitze angeordnet sind, die etwas geneigt zur Richtung der an diesen Wänden auftretenden Luftstromlinien verlaufen und mit die obere Begrenzung der Schlitze bildenden, nach außen und etwas nach unten gerichteten Abdeckstreifen versehen sind, so daß die Luft während der Fahrt sich an den Abdeckstreifen staut und gleichsam in den Motorraurn eingepreßt wird.According to the invention, the air supply in the engine compartment achieved in that slots are arranged in the side walls of the engine compartment cover which are slightly inclined to the direction of the air flow lines occurring on these walls run and with the upper limit of the slots forming, outward and something downward facing cover strips are provided so that the air during the Ride is jammed on the cover strips and pressed into the engine compartment, as it were will.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch veranschaulicht. Es zeigen Abb. i in schaubildlicher Darstellung ein Heckmotorfahrzelrg mit erfindungsgemäß angeordneten Schlitzen und Abb. 2 im größeren Maßstabe einen Querschnitt durch die Schlitze.The drawing shows an exemplary embodiment of the subject matter of the invention illustrated schematically. Fig. I shows a diagrammatic representation Heckmotorfahrzelrg with slots arranged according to the invention and Fig. 2 in the larger Scale a cross-section through the slots.

In den Seitenwänden des Motorraümdeckels i sind annähernd in Richtung der Luftstromlinien verlaufende Schlitze 2 und oberhalb dieser Schlitze parallel dazu Abdeckblechstreifen 3 vorgesehen, deren Unterseiten die obere Begrenzung der Schlitze bilden. Die Schlitze 2 und somit auch die Abdeckble:chstreifen 3 sind gegenüber den Luftstromlinien schwach nach hinten unten geneigt. Ferner sind die Abdeckstreifen 3 nach außen und etwas nach unten gerichtet, so daß sie die Luft von außen in (las Innere des Moto.rrauines hineinleiten. Durch diese Anordnung wird nicht nur die Stromlinienform des Wagenkastens besser eingehalten, sondern es wird auch ein besseres Aussehen des Fahrzeuges erzielt, weil die hervorstehenden, in der Längsrichtung verlaufenden Schlitzränder die -Möglichkeit verschiedenartiger Verzierungen, z. B. durch Verchromen o. dgl., bieten.In the side walls of the engine compartment cover i are approximately in the direction the air stream lines extending slots 2 and above these slots parallel for this purpose cover sheet strips 3 are provided, the undersides of which are the upper limit of the Form slots. The slots 2 and thus also the cover plate 3 are opposite the air stream lines inclined slightly backwards and downwards. Furthermore, the cover strips 3 directed outwards and a little downwards, so that the air from the outside into (read Lead inside the Moto.rrauines. With this arrangement, not only the Streamlined shape of the car body is better maintained, but it will also be a better one Appearance of the vehicle achieved because the protruding, in the longitudinal direction running slot edges the possibility of various decorations, z. B. by chrome plating o. The like. Offer.
