Description

Es sind Luftfilteranordnungen an Krafträdern und. Motorfahrrädern bekannt, bei denen zum Zweck der Ansaugschalldämpfung die Luft durch den hohlen Rohr- bzw. Kastenrahmen an einer möglichst hoch gelegenen Stelle angesaugt wird und bei denen der Vergaser an diesen Rahmen mittels Stutzen und Anschlußrohrstücken angeschlossen ist. Bekannt ist ferner, den Filter am Eingang der Ansaugluft in den Hohlrahmen, und zwar in diesen hineinragend, anzuordnen. Auch wurde vorgeschlagen, bei Krafträdern im rückwärtigen Teil des Motorgehäuses einen Ringfilter konzentrisch zu dort befindlichen Lufteintrittsschlitzen so anzuordnen, daß die zunächst außerhalb des Filterumfanges in das Motorgehäuse eintretende Luft nach mehrmaliger Umlenkung und Durchsetzen des Filters durch dessen Mittelöffnung in die Vergaserleitung strömt.There are air filter arrangements on motorcycles and. Motorcycles known, in which the air through the hollow for the purpose of intake sound attenuation Pipe or box frame is sucked in as high as possible and where the carburetor is attached to this frame by means of a socket and connecting pipe pieces connected. It is also known, the filter at the entrance of the intake air in the To arrange a hollow frame, namely protruding into it. It was also suggested in the case of motorcycles, a concentric ring filter in the rear part of the motor housing to be arranged there air inlet slots so that the first outside around the filter circumference, air entering the motor housing after being deflected several times and flowing through the filter through its central opening into the carburetor conduit.

Von diesem Stand der Technik unterscheidet sich der Erfindungsgegenstand dadurch, daß der Filter im Innern des Hohlrahmens, und zwar an der Stelle des Austritts der Ansaugluft aus dem Hohlrahmen angeordnet ist und die Zuführung der Luft zum Hohlrahmen durch eine Öffnung im Rahmensteuerkopf erfolgt.The subject matter of the invention differs from this prior art in that the filter is inside the hollow frame, at the point of exit the intake air is arranged from the hollow frame and the supply of air to the Hollow frame takes place through an opening in the frame control head.

Durch diese Kombination wird der Vorteil erhalten, daß die Luft schon in möglichst staubarmem Zustand angesogen, auf einem möglichst langen Weg durch den Hohlrahmen hindurch beruhigt und vorgereinigt und erst dann den nach außen geschützten Filter zugeführt wird. Es fallen mithin die sonst so störenden Verschmutzungen des Filters fort, die den Fahrbetrieb sehr unangenehm beeinträchtigen können. Insbesondere für Krafträder und Motorfahrräder (Mopeds) ist die erwähnte erfinderische Maßnahme von hohem Wert, da tunlichst alles aufgewendet werden sollte, um den störungsfreien Dauerbetrieb der hier in Betracht kommenden kleinen Motoren zu gewährleisten.This combination has the advantage that the air is already sucked in with as little dust as possible, through as long as possible the hollow frame calms down and pre-cleaned and only then the outwardly protected Filter is fed. The otherwise annoying soiling of the Filters continue, which can have a very unpleasant effect on driving. In particular for motorcycles and motorcycles (mopeds) is the inventive measure mentioned of great value, since everything should be done to ensure that it runs smoothly To ensure continuous operation of the small motors in question here.

In der Zeichnung sind zwei verschiedene Ausführungsbeispiele der Erfindung dargestellt. Darin bedeutet 1 das Luftfiltergehäuse, 2 ein vom Luftfilter zum Vergaser führendes Rohrstück, 3 einen Rohrstutzen am Vergaser und 4 einen am Steuerkopf des Rahmens vorgesehenen Durchbruch für den Lufteintritt.In the drawing are two different embodiments of the invention shown. 1 means the air filter housing, 2 means one from the air filter to the carburetor leading pipe section, 3 a pipe socket on the carburetor and 4 one on the control head of the Frame provided breakthrough for the air inlet.

Bei der Ausführungsform nach Fig. I ist der vollständig im Innern des Rahmens untergebrachte Filter äußerlich .nicht sichtbar. Nach außen hin treten lediglich das Verbindungsstück 3 und der Durchbruch am Rahmenkopf in Erscheinung. Die hier eintretende Luft durchzieht den Hohlraum auf langem Wege und strömt über den Luftfilter und den hier beispielsweise in der Symmetrieebene des Rahmens anschließenden Rohrstutzen 3 zum Vergaser. Diese Ausführungsform hat den besonderen Vorteil, daß sie sich unauffällig in die Gesamtkonstruktion einfügt.In the embodiment according to FIG. I, it is completely inside The filters placed in the frame are not visible from the outside. Step outside only the connector 3 and the opening on the frame head appear. The air entering here pulls through the cavity for a long time and flows over it the air filter and the adjoining one here, for example, in the plane of symmetry of the frame Pipe socket 3 to the carburettor. This embodiment has the particular advantage that it blends inconspicuously into the overall construction.

Fallweise kann aber auch eine Anordnung zweckmäßig sein, bei welcher der gleichfalls im Rahmeninnern angeordnete Filter mit seinem Gehäuse eine Öffnung der Rahmenwand abdeckt, so daß das Filtergehäuse an dieser Öffnung sichtbar wird. Eine solche Ausführungsform zeigt Fig.2. Das Luftfiltergehäuse 1 ist unmittelbar mit dem Rahmen verbunden und deckt eine Öffnung in der Seitenwandung des Rahmens ab. Die Verbindung zum Vergaser ist durch ein besonderes Rohrstück 2 hergestellt. Im übrigen ist auch bei dieser Ausführungsform der in Fig. I dargestellte Durchbruch am Steuerkopf vorzusehen, so daß, wie bei dem ersten Ausführungsbeispiel, die Luft auf langem Wege dem an ihrer Austrittsstelle aus dem Rahmen angebrachten, in diesen geschützt liegenden Luftfilter zuströmt.In some cases, however, an arrangement in which the filter, which is also arranged inside the frame, has an opening with its housing covers the frame wall so that the filter housing is visible at this opening. Such an embodiment is shown in FIG. The air filter housing 1 is immediate connected to the frame and covers an opening in the side wall of the frame away. The connection to the carburetor is made by a special pipe section 2. In addition, the breakthrough shown in FIG. I is also in this embodiment to be provided on the control head, so that, as in the first embodiment, the air on a long way to the one attached to its exit point from the frame, in this protected air filter flows in.
