Description

Die Erfindung betrifft ein einziehbares Flugfahrzeuggestell mit radtragenden Federbeinen, von denen jedes aus zwei oder mehreren um ein oder mehrere Verbindungsgelenke knickbaren Teilen besteht. Bei den bekannten Federbeinen jeder Art sind jedoch die Federungs- bzw. Dämpfungsmittel nur im unteren, radtragenden Teil vorgesehen.The invention relates to a retractable aircraft frame with wheel-bearing spring struts, each of which consists of two or more parts that can be bent around one or more connecting joints. With the known However, the suspension or damping means are only provided in the lower, wheel-bearing part.

Um gegenüber den bekannten Einrichtungen eine größere Federungs- bzw. Dämpfungswirkung zu erzielen, enthält erfindungsgemäß jeder knickbare Teil des Federbeines Stoßdämpfungsmittel, die in der gestreckten Lage des Federbeins kraftschlüssig hintereinandergeschaltet sind. Dabei bilden die Einzelfederwege der Dämpfungsvorrichtungen den -Gesamtfederweg des Federbeines.In order to have a greater suspension or damping effect compared to the known devices to achieve, according to the invention, each articulated part of the strut contains shock absorbing means, which are frictionally connected in series in the extended position of the shock absorber are. The individual spring travel of the damping devices form the total spring travel of the shock absorber.

Der in den bekannten knickbaren Federbeinen vorhandene obere Leerraum ist somit in vorteilhafter Weise für den Einbau von Dämpfungsmitteln ausgenutzt.The upper empty space present in the known articulated struts is thus advantageously used for the installation of damping means.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Abb. ι zeigt schematisch das Federbein im aus- und eingefahrenen Zustand sowie in einer Zwischenstellung. An exemplary embodiment of the invention is shown in the drawing. The fig. Ι shows schematically the strut in the extended and retracted state and in an intermediate position.

ι ist der Rumpf mit Tragflügel 2, in welchem bei 3 das aus Oberteil 4 und Unterteil 5 mit Rad 6 bestehende, um Gelenk 7 knickbare Federbein des Fahrgestells angelenkt ist. Der Oberteil 4 des Federbeines enthält eine arbeitaufnehmende Dämpfungsvorrichtung 8, der Unterteil 5 ebenfalls eine solche Vorrichtung 9. In der gestrecken Lage des Federbeines, also im ausgefahrenen Zustand, sind diese beiden arbeitaufnehmenden Dämpfungsvorrichtungen zwangsläufig kraftschlüssig hintereinandergeschaltet. Die Strebe 10 ist bei 11 im Flügel, bei 12 am unteren Teil 5 des knickbaren Federbeines angelenkt. Das Einziehen des Federbeines erfolgt im übrigen durch an sich bekannte Einziehvorrichtungen. Die Abb. 2 und 3 zeigen schematisch einen Teil des Federbeines im unbelasteten und belasteten Zustand. <5ι is the fuselage with the wing 2, in which at 3 the upper part 4 and lower part 5 is articulated with wheel 6 existing, around joint 7 articulated strut of the chassis. The upper part 4 of the strut contains a work-absorbing damping device 8, the lower part 5 also has such a device 9. In the extended position of the strut, so in the extended state, these two work-absorbing damping devices inevitably frictionally connected in series. The strut 10 is at 11 in the wing, at 12 on the lower part 5 of the articulated strut. The retraction of the strut takes place in the rest by pull-in devices known per se. Figs. 2 and 3 show schematically a Part of the shock absorber in the unloaded and loaded state. <5
