Description

Einrichtung zur Zuführung von Frischluft in den geschlossenen Führerraum .von. Kraftfahrzeugen Bei Kraftfahrzeugen mit geschlossenem Führerraum ist es bekannt, in den von der Stirnwand schräg zur Längsrichtung des Fahrzeugs verlaufenden Seitenwänden einstellbare Luftklappen anzubringen, welche den Zweck haben, bei Fahrt Frischluft einzuführen und dadurch eine stärkere Erwärmung der Luft in dem Führerraum zu verhindern bzw. die Atmungsluft frisch zu halten.Device for supplying fresh air to the closed driver's cab .from. Motor vehicles In motor vehicles with a closed driver's cab, it is known in the side walls running from the front wall at an angle to the longitudinal direction of the vehicle to attach adjustable air flaps, which have the purpose of fresh air when driving introduce and thereby prevent a stronger heating of the air in the driver's cab or to keep the air we breathe fresh.

Bei den bekannten Einrichtungen dieser Art tritt aber der Nachteil auf, daß die durch die offenen Luftklappen eintretende kalte Luft' unmittelbar auf die Beine des Fahrpersonals trifft, so daß dieses in dem kalten Luftzug sitzt. Daraus können sich gesundheitliche Schädigungen ergeben, und das Aufhalten der Klappen wird bei niedriger Außentemperatur auf die Dauer auch unmöglich.In the known devices of this type, however, the disadvantage occurs on that the cold air entering through the open air flaps' immediately hits the legs of the drivers so that they sit in the cold draft. From it health damage can result, and the opening of the valves becomes impossible in the long run when the outside temperature is low.

Durch die Erfindung wird dieser Nachteil vermieden. Die Erfindung besteht darin, daß im Innern des Führerraumes an den äußeren Begrenzungsrändern der Luftklappenöffnungen gekrümmte Leitwände angeschlossen sind, durch welche die zuströmende Frischluft gegen die Stirnwand geleitet wird, bevor sie sich in dem Raume verteilt.The invention avoids this disadvantage. The invention consists in the fact that inside the driver's cab at the outer boundary edges curved baffles are connected to the air flap openings, through which the incoming fresh air is directed against the front wall before it is in the Distributed spaces.

Es wird auf diese Weise erreicht, daß die Strömungsgeschwindigkeit der Frischluft an der Stirnwand verringert wird, ferner aber die Luft sich mäßig erwärmt, bevor sie mit dem Fahrpersonal in Berührung kommt. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in Abb. i in Seitenansicht des Führerraumes und in Abb. 2 im Grundriß mit Schnitt durch die schräge Seitenwand des Führerraumes veranschaulicht.It is achieved in this way that the flow rate the fresh air at the front wall is reduced, but furthermore the air is moderately warmed up before it comes into contact with the driver. In the drawing is an embodiment of the invention in Fig. i in side view of the driver's cab and in Fig. 2 in plan with a section through the sloping side wall of the driver's cab illustrated.

In den schräg nach hinten bzw. nach der Seite verlaufenden Seitenwänden a sind die bekannten einstellbaren Luftklappen b vorgesehen, mit denen ein kreisbogenförmiges Siebblech c verbunden ist, durch welches das Eindringen von Staub in den Führerraum d vermieden wird. Im Innern des Raumes d sind an den seitlichen Außenkanten der Luftklappenöffnungen e gekrümmte Leitwände f vorgesehen, durch welche die einströmende Luft in Richtung auf die Stirnwand geleitet wird, wie durch Pfeile in der Abb. 2 angedeutet ist.In the side walls that run obliquely to the rear or to the side a, the known adjustable air flaps b are provided, with which a circular arc-shaped Sieve plate c is connected through which the ingress of dust into the driver's cab d is avoided. Inside the room d are on the lateral outer edges of the Air flap openings e curved baffles f provided through which the inflowing Air is directed towards the front wall, as indicated by arrows in Fig. 2 is indicated.
