Abstract

The invention relates to an aerodynamic, easily detachable panelling for the underside of motor vehicles, in particular passenger cars and convertibles. In order to obtain a lightweight panelling which does not restrict the ground clearance of the vehicle, there is provision according to the invention for it to be composed of a flexible material, such as, for example, a plastic film which can yield to the movements of the wheel guidance elements.

Description

nAerodynamische Verkleidung für dienAerodynamic fairing for the

Unterseite von Kraftwagen" Die Erfindung betrifft eine aerodynamische, leicht lösbare Verkleidung für die Unterseite von Kraftwagen, insbesondere Personen- und Kombinationskraftwagen.Underside of motor vehicles "The invention relates to an aerodynamic, easily detachable cladding for the underside of motor vehicles, especially passenger and station wagons.

Zur aerodynamischen Optimierung eines Kraftwagens ist es unbedingt erforderlich, auch dessen Unterseite möglichst glattflächig zu gestalten, da dies einen wesentlichen Einfluß auf den c -Wert des Fahrzeugs hat. Es ist deshalb bereits vorgeschlagen worden (DE-Gm 18 85 798), die Fahrzeugunterseite mit einer eigensteifen Platte zu verkleiden. Abgesehen vom relativ hohen Gewicht einer solchen Platte ergeben sich bei der praktischen Ausführung dieses Gedankens Schwierigkeiten im Bereich der Radführungsglieder, deren Bewegung durch die Abdeckung nicht beeinträahtigt werden darf. Die Platte müßte also in einem ausreichenden Abstand von den Radführungsgliedern verlaufen, was jedoch zu einer wesentlichen Verringerung der Bodenfreiheit des damit ausgestalteten Fahrzeugs führen würde.It is essential for the aerodynamic optimization of a motor vehicle necessary to make its underside as smooth as possible, as this has a significant influence on the vehicle's c value. It is therefore already been proposed (DE-Gm 18 85 798), the vehicle underside with an inherently rigid Clad plate. Apart from the relatively high weight of such a plate difficulties arise in the practice of this idea the wheel guide members, the movement of which is not affected by the cover may be. The plate should therefore be at a sufficient distance from the wheel guide members run, which, however, leads to a substantial reduction in the ground clearance of the thus designed vehicle would lead.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, eine möglichst leichttevi¢htite Abdeckung für die Unterseite von Kraftwagen zu schaffen, die praktisch keine Verringerung der Bodenfreiheit des Fahrzeugs mit sich bringt.The present invention was therefore based on the object as possible Leichttevi ¢ htite cover for the underside of motor vehicles to create that practical does not result in a reduction in the ground clearance of the vehicle.

Diese Aufsabe wird bei einer Vorkleidungder eingangs definierten Gattung erfindungsgemäß gelöst, daß sie aus einem biegsamen Material wie z.B. einer Kunststoffolie, besteht, die den Bewegungen der Radführungsglieder ausweichen kann.In the case of a pre-clothing, this task is of the type defined at the beginning solved according to the invention that they are made of a flexible material such as a plastic film, exists, which can evade the movements of the wheel guide members.

Die Verkleidung kann dabei entweder aus einem elastischen Material bestehen oder aber sie kann elastisch, z.B. huber Zugfedern, am Wagenboden befestigt sein.The cladding can either be made of an elastic material or it can be attached to the floor of the car elastically, e.g. by means of tension springs be.

In weiterer Ausgestaltung der erfindungsgemäßen Verkleidung ist vorgesehen, daß sie sich lediglich über den Bereich der Vorder- und/oder Hinterradaufhängungen des Fahrzeugs erstreckt und diese nach unten abdeckt.In a further embodiment of the cladding according to the invention it is provided that they only extend over the area of the front and / or rear wheel suspensions of the vehicle and covers this down.

Schließlich kann es noch vorteilhaft sein, wenn in Fahrtrichtung vor der Verkleidung eine Abdeckleiste od. dgl. angeordnet ist, die ein Hinterströmen derselben verhindert.Finally, it can be advantageous if facing in the direction of travel the cladding a cover strip or the like. Is arranged that a rear flow the same prevented.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing schematically illustrated embodiment will be explained in more detail.

An der Unterseite 1 des in der Zeichnung dargestellten Personenkraftwagens 2 ist im Bereich der Vorder- und Hinterachse jeweils eine aus einer Folie od. dgl. bestehende Verkleidung 3 angeordnet, die die Radführungsglieder 4 abdeckt und die über Zugfedern 3 elastisch an der Unterseite 1 aufgehängt ist.On the underside 1 of the passenger car shown in the drawing 2 is in the area of the front and rear axles in each case one made of a film or the like. existing fairing 3 arranged, which covers the wheel guide members 4 and the above Tension springs 3 are elastically suspended from the underside 1.

Bei starken Ausfederwagabewegungen der Radführungsglieder 4 kann die Verkleidung 3 aufgrund ihrer elastischen Aufhängung ausweichen.With strong Ausfederwagabewegungen the wheel guide members 4 can Dodge cladding 3 due to its elastic suspension.

Anders als beim dargestellten Ausführungsbeispiel wäre es natürlich auch möglich, daß sich die Verkleidung ein- oder mehrteilig über die ganze Fahrzeuglänge erstreckt und z.B.In contrast to the illustrated embodiment, it would be natural It is also possible that the cladding is in one or more parts over the entire length of the vehicle extends and e.g.

im Bereich der Stoßfänger rolloartig befestigt ist.is attached like a roller blind in the area of the bumper.
