Description

Ansauggeräuschdämpfung bei Motorrädern, insbesondere Motorfahrrädern Im modernen Fahrzeug-, insbesondere Motorradbau, geht unter anderem das allgemeine Bestreben dahin, das Ansauggeräusch der dem Vergaser zugeführten Luft zu dämpfen. Zu diesem Zweck wurden verschiedene Einrichtungen und Maßnahmen vorgeschlagen. In diesem Zusammenhang ist es auch bekannt, die Ansaugluft bei Motorrädern einem hohlen Rahmenbauteil zu entnehmen, der eine Dämpfungskammer bildet und an den der Vergaser mit seinem Saugstutzen angeschlossen ist; der Luftfilter ist dabei in die Eintrittsöffnung der Dämpfungskammer eingebaut.Intake noise suppression in motorcycles, in particular motorcycles In modern vehicle, especially motorcycle construction, the general goes, among other things Endeavor to dampen the suction noise of the air supplied to the carburetor. Various facilities and measures have been proposed to this end. In In this context, it is also known that the intake air in motorcycles is a hollow one To take frame component, which forms a damping chamber and to which the carburetor is connected with its suction nozzle; the air filter is in the inlet opening built into the damping chamber.

Weiter ist es bekannt, an einem Rahmenrohr eine kastenförmige Dämpfungskammer anzubringen, welche gleichzeitig zur Aufhängung des Motors dient. Dabei ist in der Dämpfungskammer zwangläufig eine Öffnung zum Anschluß des Vergasers und eine Lufteinlaßöffnung vorgesehen. Diese Ausbildung hat den Nachteil, daß durch de Öffnungen eine Schwächung des tragenden Querschnittes der Dämpfungskammer eintritt. Durch das Vibrieren des Motors können bei längerem Betrieb Ermüdungserscheinungen in der Aufhängung auftreten, die sieh insbesondere in dem durch die Öffnungen geschwächten Querschnitt auswirken, wodurch die Dämpfungskammer und damit die Motoraufhängung zerstört werden können.It is also known to have a box-shaped damping chamber on a frame tube to be attached, which also serves to suspend the engine. It is in the Damping chamber necessarily has an opening for connecting the carburetor and an air inlet opening intended. This training has the disadvantage that a weakening by de openings of the supporting cross-section of the damping chamber occurs. By vibrating the If the engine is operated for a long time, the suspension may show signs of fatigue, which have an effect in particular in the cross-section weakened by the openings, which can destroy the damping chamber and thus the engine mount.

Gegenstand der vorliegenden Erfindung ist eine Ansauggeräuschdämpfungsvorrichtung bei Motorrädern, insbesondere bei Motorfahrrädern, mit einer vor den Saugstutzen des Vergasers geschalteten, am Fahrzeugrahmen in Form eines Anbauteiles angeordneten Dämpfungskammer, bei der die vorerwähnten Nachteile vermieden werden. Zu diesem Zweck wird ein Hohlkörper vorgesehen, der einen im wesentlichen querschnittsgleichen, an sich bekannten langgestreckten Dämpfungskammerraum besitzt und sich in seiner Längserstreckung dem Formverlauf eines Rahmenrohres anpaßt. Dieser Hohlkörper kann das Rahmenrohr ganz oder teilweise umschließen und bildet die Dämpfungskammer für die Ansaugluft und ist an diesen der Vergaser mit seinem Saugstutzen angeschlossen. Der Hohlkörper kann dabei in sich. allseitig geschlossen und auf irgendwelche einfache Weise mit dem Rahmenrohr verbunden sein, z. B. durch Punktschweißen od. dgl. Es ist auch möglich, die vorzugsweise als Blechkörper ausgebildete Dämpfungskammer so auszubilden, daß der Hohlraum auf der Rückseite vom Rahmenrohr abgeschlossen wird, also der Blechkörper nicht in sich geschlossen ausgeführt ist.The subject of the present invention is an intake noise suppression device with motorcycles, especially with motorcycles, with one in front of the suction nozzle of the carburetor, arranged on the vehicle frame in the form of an attachment Damping chamber in which the aforementioned disadvantages are avoided. To this Purpose, a hollow body is provided, which has an essentially identical cross-section, has known elongated damping chamber space and is in his Longitudinal extension the Adjusts the shape of a frame tube. This Hollow body can completely or partially enclose the frame tube and form the damping chamber for the intake air and the carburetor is connected to this with its suction nozzle. The hollow body can be in itself. closed on all sides and in some simple way Way to be connected to the frame tube, for. B. by spot welding or the like. It is also possible, the damping chamber, which is preferably designed as a sheet metal body to form so that the cavity on the back of the frame tube is closed is, so the sheet metal body is not designed to be closed in itself.

Diese erfindungsgemäße Ausbildung der Dämpfungskammer hat den Vorteil, daß eine Schwächung des Rahmenrohres oder eines anderen tragenden Bauteiles durch Vorsehung von Öffnungen für den Lufteinlaß und Luftaustritt nicht eintritt. Andererseits ist es leicht möglich, diese Dämpfungskammer in gefälliger Form am Rahmen vorzusehen oder auch nachträglich anzubringen. Die Dämpfungskammer kann gleichzeitig zur Verkleidung von irgendwelchen Kabeln oder sonstigen Leitungen dienen.This design of the damping chamber according to the invention has the advantage that a weakening of the frame tube or another load-bearing component through Provision of openings for air inlet and air outlet does not enter. on the other hand it is easily possible to provide this damping chamber in a pleasing form on the frame or to be attached later. The damping chamber can also be used for cladding of any cables or other lines.

Der Luftfilter wird vorzugsweise an der Lufteinlaßöffnung der Dämpfungskammer angeordnet. In der Dämpfungskammer bzw. an deren Luftein-und -auslaßöffnungen können Leitmittel zur besseren Luftstromführung vorgesehen werden.The air filter is preferably located at the air inlet opening of the damping chamber arranged. In the damping chamber or at its air inlet and outlet openings Guide means are provided for better air flow guidance.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Prinzip dargestellt.In the drawing, an embodiment of the invention is in principle shown.

Das Rahmenrohr i, an dem der Motor 2 befestigt ist, trägt den langgestreckten Hohlkörper 3, der an den Stellen 4 mit dem Rahmenrohr i durch Punktschweißen verbunden ist. Es ist dabei nicht erforderlich, daß der als Dämpfungskammer dienende Hohlkörper 3 vollkommen luftdicht ist.The frame tube i, to which the engine 2 is attached, carries the elongated Hollow body 3, which is connected at points 4 to the frame tube i by spot welding is. It is not necessary that the hollow body serving as a damping chamber 3 is completely airtight.

Wie aus Fig. 2 ersichtlich, kann der Hohlkörper 3 auf das Rahmenrohr i aufgesetzt werden, so daß das Rahmenrohr i deren rückwärtige Begrenzung bildet. Es ist auch möglich, wie aus Fig. 3 ersichtlich, den Hohlkörper mittels einer eigenen, z. B. angeschweißten Rückenwand 9, in sich .geschlossen auszubilden und an: den Stellen 4 mit dem Rahmenrohr i zu verbinden. Die Querschnittsform des Hohlkörpers 3 kann entsprechend den jeweiligen Gegebenheiten und Erfordernissen der Querschnittsform des Rahmens angepaßt werden. Der Luftfilter 5 ist an der Lufteinlaßöffnung 6 des Hohlkörpers 3 angeordnet. Der Vergaser 7 ist über den Ansaugstutzen 8 an den Hohlkörper 3 angeschlossen.As can be seen from Fig. 2, the hollow body 3 can be placed on the frame tube i are placed so that the frame tube i forms the rear boundary thereof. It is also possible, as can be seen from Fig. 3, the hollow body by means of its own, z. B. welded back wall 9, to form closed in itself and to: the Connect 4 with the frame tube i. The cross-sectional shape of the hollow body 3 can according to the respective circumstances and requirements of the cross-sectional shape of the frame. The air filter 5 is at the air inlet opening 6 of the Hollow body 3 arranged. The carburetor 7 is connected to the hollow body via the intake port 8 3 connected.
