Abstract

A slipstream guidance groove is formed along each side of a vehicle (1), above the wheel arches. The groove (2) produces a curtain of air which moves outwards to prevent road spray from being thrown up onto the side windows. The design is especially useful for buses with their large window area. The guides are pressed into the side panel and widen towards the rear. They have a smooth profile to generate a swirl effect. The rounded edges of the guides prevent damage to cleaning equipment and provide a decorative trim effect.

Description

11Vorrichtung zum Schmutzfreihalten der Seiten-11 Device for keeping the side panels free of dirt

scheiben von Kraftwagen, insbesondere Nutzkraftwagen Die Erfindung betrifft eine Vorrichtung zum Schmutzfreihalten der Seitenscheiben von Kraftwagen, insbesondere Nutzkraftwagen. windows of motor vehicles, in particular commercial vehicles The invention relates to a device for keeping the side windows of motor vehicles free of dirt, especially commercial vehicles.

Es sind bereits Vorrichtungen zur Verminderung der Verschmutzung der Seitenscheiben von Nutzkraftwagen bekannt, bei denen auf die Stirnfläche des Fahrzeugs auftreffende Luft durch geschlossene Kanäle zur Seitenwand geleitet wird, wo sie durch eine düsenartig ausgebildete Austrittsöffnung ausgeblasen wird und so einen Luftstrom bildet, der die Seitenscheiben gegen aufgewirbelten Schmutz abschirmt. Der wesentliche Nachteil einer solchen Einrichtung ist darin zu sehen, daß ein solcher Luftstrom schon bald nach Verlassen des Kanals seine Wirkung verliert, so daß er nur auf einer sehr begrenzten Länge seine Aufgabe erfüllt. Weitere Nachteile sind darin zu sehen, daß geschlossene Kanäle sehr anfällig gegen Umwelteinflüsse - wie z.B. Eis oder Schnee - sind und durch die Bürsten von Waschanlagen nicht gereinigt werden können.There are already devices to reduce the pollution of the Side windows of commercial vehicles known where on the front surface of the vehicle impinging air is directed through closed channels to the side wall, where it is blown out through a nozzle-like outlet opening and so one Forms air flow that shields the side windows against blown dirt. The main disadvantage of such a device is to be seen in the fact that such Air flow loses its effect soon after leaving the duct, so that it only fulfills its task over a very limited length. Other disadvantages are to see that closed channels are very susceptible to environmental influences - such as e.g. ice or snow - are not cleaned by the brushes of washing systems can be.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diese Nachteile zu vermeiden und insbesondere eine Vorrichtung zu schaffen, die auf der ganzen Länge des Fahrzeugs wirksam wird.The present invention was therefore based on the object of addressing these disadvantages to avoid and in particular to create a device that runs along the entire length of the vehicle takes effect.

Diese Aufgabe wird gelöst durch die im kennzeichnenden Teil des Anspruchs 1 angeführten Merkmale.This problem is solved by the characterizing part of the claim 1 listed features.

Eine besonders gute Wirkung wird erreicht, wenn sich der Luftführungskanal auch um den Bug des Fahrzeugs herumzieht und sich zum Bug hin trichterförmig erweitert und vertieft.A particularly good effect is achieved when the air duct also pulls around the bow of the vehicle and widens in a funnel shape towards the bow and deepened.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigen Fig. 1 in einer Prinzipdarstellung den vorderen Teil einer Seitenansicht eines Nutzkraftwagens, der mit einer erfindungsgemäßen Luftführungsvorrichtung ausgestattet ist, Fig. 2 einen Schnitt nach der Linie II-II in Fig. i, und Fig. 3 eine Prinzipdarstellung der Wirkungsweise der Einrichtung.The object of the invention is to be based on one in the Drawing schematically illustrated embodiment will be explained in more detail. In the drawing, Fig. 1 shows the front part of a schematic diagram Side view of a utility vehicle equipped with an air guiding device according to the invention is equipped, Fig. 2 shows a section along the line II-II in Fig. i, and Fig. 3 shows a basic illustration of the mode of operation of the device.

Der in der Zeichnung schematisch dargestellte Nutzkraftwagen weist unterhalb seiner Seitenscheiben i einen eingezogenen, nach außen offenen Luftführungskanal 2 auf, der sich vorzugsweise über die ganze Länge der zu schützenden Fläche erstreckt und sich auch um die Stirnwand des Fahrzeugs herumzieht, wobei er im Bereich der vorderen Ecken des Fahrzeugs trichterförmig erweitert und vertieft ausgebildet ist.The commercial vehicle shown schematically in the drawing has below its side windows i a retracted, outwardly open air duct 2, which is preferably over the entire length of the to be protected area extends and also pulls around the bulkhead of the vehicle, being in the area the front corners of the vehicle funnel-shaped expanded and deepened is.

In der Darstellung nach Fig 3 ist mit Pfeilen 3 die Bewegung der von vorn anströmenden Luft angedeutet, die den von unten kommenden Schmutz - Pfeil 4 - daran hindert, bis zu den Seitenscheiben aufzusteigen. Wesentlich dabei ist, daß der aus dem Kanal 2 austretenden Luft - Pfeil 3 - durch entsprechende Formgebung des Kanals 2 eine nach unten gerichtete Bewegung aufgezwungen wird.In the illustration according to FIG. 3, arrows 3 indicate the movement of the The air flowing in at the front is indicated, which removes the dirt coming from below - arrow 4 - prevents you from climbing up to the side windows. It is essential that the air emerging from channel 2 - arrow 3 - by appropriate shaping of the channel 2 a downward movement is imposed.
