Abstract

The front spoiler for the lorry comprises an angled plate of elastic material mounted under the bumper strip (10) with a narrow front face (4) and a wide bottom face. The ends of the spoiler are reinforced by thickened seams (1, 2) and the whole assembly is held under the bumper with one fitting and by struts (6) pivoted on the chassis. The elastically mounted on that it is not damaged by stones or by high obstructions.

Description

Bugschürze für Großkraftwagen, insbesondere Front apron for large vehicles, in particular

Lastkraftwagen Die Erfindung betrifft eine Bugschüre fUr Großkraftwagen, insbesondere Lastkraftwagen, und dlewo vor allem zur Verminderung des Luftwiderstands, zum Fernhalten bzw. Abweisen von hochgeschleuderten Teilen und zur Verbesserung des äußeren Eindrucks. Trucks The invention relates to a front apron for large vehicles, especially trucks, and dlewo especially to reduce air resistance, to keep away or reject parts that have been thrown up and to improve the external impression.

Die bekannten Bugschürzen haben sich nicht bewährt.The well-known front aprons have not proven themselves.

Die Versuchsvarianten mit nur einer Randversteifung vorne haben nur unzufriedensteXlende Befestigungsmöglichkeiten.The test variants with only one edge stiffener at the front only have unsatisfactory mounting options.

Es ist deshalb Aufgabe der Erfindung, eine in jeder Weise verbesserte Bugschürze auEtuzeigen, die allen heutigen Anforderungen genügt.It is therefore the object of the invention to provide an improved in every way Show the front apron that meets all of today's requirements.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst, während die Ansprüche 2 bis 3 die weiter vorteilhafte Ausgestaltung der Bugschürze betreffen.This task is with the characterizing features of the claim 1 solved, while claims 2 to 3 the further advantageous embodiment of the Front apron concern.

Die Erfindung wird nun anhand der Zeichnung mit einem Ausführungsbeispiel erläutert; dabei zeigt Fig. 1 ein Lastkraftwagenvorderteil in Seitenansicht mit einer erfindungsgemäßen Bugschürze im Querschnitt, Fig. 2 diese Bugschürze allein in Draufsicht.The invention is now based on the drawing with an embodiment explained; Fig. 1 shows a truck front part in side view a front apron according to the invention in cross section, FIG. 2 this front apron alone in plan view.

Gemäß Fig. 1 ist an der vorderen Stoßstange 10 eines Lastkraftwagens unten eine Bugschürze angeordnet; diese ist gemäß Fig. 2 an die Grundrißfläche der Stoßstange angeglichen, reicht aber in Fahrzeuglängsrichtung über sie nach hinten hinaus, nämlich bis fast zu den Vorderrädern. Die Bugschürze ist vorn und seitlich mit einer Abrundung 4 bis zu einem in einer waagrechten Ebene liegenden, nach innen zu verstärktem Rand 1 hochgezogen; an diesem ist sie mittels mehrerer Schrauben 9 an der Stoßstange befestigt. Auf diese Weise wird eine geschlossene untere und seitliche Frontabdeckung des Fahrzeugs erzielt.1 is on the front bumper 10 of a truck a front apron arranged below; this is shown in FIG. 2 to the plan area of the Adjusted bumper, but extends over it to the rear in the longitudinal direction of the vehicle out, namely almost to the front wheels. The front apron is front and side with a rounding 4 up to one lying in a horizontal plane, inward pulled up to reinforced edge 1; it is attached to this by means of several screws 9 attached to the bumper. In this way it becomes a closed lower and side front cover of the vehicle achieved.

Die Bugschürze ist ferner an ihrem hinteren, in einer senkrechten Ebene liegenden Rand 2 nach außen zu verstärkt ausgebildet. Schließlich weist sie eine in Fahrzeuglängsrichtung liegende, nach innen reichende Verstärkungsrippe 3 auf, an der ein Gelenk 10a angeordnet ist. Von diesem führt eine Stütze 6 über ein weiteres Gelenk 10b zum Fahrzeugrahmen 7; auf diese Weise ist die mit der bestimmungsgemäß bei Stößen nachgebenden Stoßstange 10 fest verbundene Bugschürze verspannungsfrei am Fahrzeugrahmen abgestützt.The front apron is also at its rear, in a vertical position Flat edge 2 is designed to be reinforced to the outside. Finally she knows an inwardly extending reinforcing rib 3 lying in the longitudinal direction of the vehicle on, on which a joint 10a is arranged. From this a support 6 leads over another joint 10b to the vehicle frame 7; in this way the with the intended use bumper 10, which yields in the event of impacts, is firmly connected to the front apron without tension supported on the vehicle frame.

Mit Rücksicht auf die herunterreichende Fahrerhaustreppe weist die Bugschürze an einem hinter der Stoßstange 10 liegenden Seitenteil eine Aussparung 5 auf.In consideration of the downward-reaching driver's cab stairs, the Front apron on a side part lying behind the bumper 10 has a recess 5 on.

In der Bugschürze sind ferner Scheinwerfer 8 konstruktiv so eingebunden, daß eine einheitliche, nur etwas profilierte Front entsteht.Headlights 8 are also structurally integrated in the front apron so that that a uniform, only slightly profiled front is created.

Zur zerstörungsfreien Aufnahme von Stößen ist die Bugschürze schließlich aus nachgiebigem, jedoch nicht zurückfederndem sondern speicherndem Werkstoff gefertigt; z. B. kann Hartgummi verwendet werden.Finally, the front apron is used for non-destructive absorption of impacts made of resilient, but not resilient, but storing material; z. B. hard rubber can be used.
