Description

Die Erfindung bezieht sich auf eine Rohrverbindung zwischen Vergaser und Ansauggeräuschdämpfer an Brennkraftmaschinen, insbesondere für Zweiradmotorfahrzeuge.The invention relates to a pipe connection between the carburetor and intake silencers on internal combustion engines, in particular for two-wheeled motor vehicles.

Kammern mit Luftfilteranordnungen zur Dämpfung des Ansauggeräusches sind bereits in verschiedenen Ausführungen bekanntgeworden. Sinn und Zweck dieser Dämpfungskammern ist, ein Vorvolumen zu schaffen, welches die Schwingungen der Ansaugluft dämpft. Ferner wird durch dieses Vorvolumen ein nahezu kontinuierliches Einströmen der Ansaugluft in die Dämpfungskammer erzielt, so daß die durch das sonst stoßweise Eintreten der Luft durch das, Filter entstehenden Geräusche fortfallen. Die zwischen Filter und Vergaser liegende Dämpfungskammer hat aber noch den Vorteil, daß sie die Steuergeräusche der Ansaugschlitze bei Zweitaktmotoren schluckt.Chambers with air filter arrangements to dampen the intake noise have already become known in various versions. Sense and purpose of this Damping chambers is to create a preliminary volume, which the vibrations of the intake air dampens. Furthermore, this pre-volume creates an almost continuous inflow the intake air is achieved in the damping chamber, so that the otherwise intermittent Entry of air through the filter noises arising noises. The between Filter and carburetor lying damping chamber has the advantage that it swallows the control noises of the intake slots in two-stroke engines.

Die Verbindung zwischen Vergaser und Dämpfungskammer wurde bisher durch starre Verbindungsrohre hergestellt, deren Montage sich oft schwierig gestaltete. Diese Schwierigkeiten traten dann besonders kraß in Erscheinung, wenn sich im Abstand zwischen Dämpfungskammer und Vergaser große Differenzen ergaben.The connection between the carburetor and the damping chamber was previously made by rigid connecting pipes, which were often difficult to assemble. These difficulties were particularly evident when they were at a distance there were large differences between the damping chamber and the carburetor.

Die Erfindung hat sich nun die Aufgabe gestellt, eine Lösung zu finden, mit welcher die vorstehenden Nachteile beseitigt werden.The invention has now set itself the task of finding a solution with which the above disadvantages are eliminated.

Gemäß der Erfindung wird dies dadurch erreicht, daß die Ansaugrohre in der Dämpfungskammer in Büchsen axial verschiebbar gelagert und in diese teleskopartig einschiebbar sind.According to the invention this is achieved in that the suction pipes mounted axially displaceably in bushes in the damping chamber and telescopically into them are retractable.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt Fig. I eine Seitenansicht des Erfindungsgegenstandes und Fig. 2 einen Schnitt nach der Ebene A-A der Fig. I.The drawing shows an embodiment of the subject matter of the invention shown. It shows FIG. I a side view of the subject matter of the invention and FIG. 2 shows a section along the plane A-A of Fig. I.

Eine Dämpfungskammer I, die sich, um ein möglichst großes Volumen zu erlangen, in ihrer Form vorzugsweise den benachbarten Bauteilen, wie dem Schutzblech 2 od. dgl., anpaßt, ist mit einem Bügel 3 am Rahmenoberzug 4 befestigt. I@ ihren Seitenwänden 5 sind beispielsweise symmetrisch zur Mittelebene der Kammer I Öffnungen 6 für zwei Luftfilter 7 vorgesehen. Diese beiden Luftfilter 7 sind durch eine Welle 8 od. dgl. miteinander verbunden und von einer Seifte aus mittels eines Hebels 9 gemeinsam verstellbar. Zwei an der Dämpfungskammer I vorgesehene Stutzen Io sind zur Führung und Lagerung teleskopartig verschiebbarer Ansaugstutzen I I mit je einer Büchse I2 ausgestattet. In eine Ringwulst der Büchsen I2 eingelegte Ringe I3 von kreisförmigem Querschnitt aus elastischem Werkstoff dienen der Abdichtung und dämpfenden Lagerung der Ansaugstutzen I I in der Dämpfungskammer I. Die Ansaugstutzen I I sind vergaserseitig auf Stutzen I4 der Mischkammern I5 aufgeschoben und auf diesen mittels Schellen 16 festgeklemmt.A damping chamber I, which is to have as large a volume as possible to obtain, in their shape, preferably the neighboring components, such as the mudguard 2 or the like., Is attached to the frame cover 4 with a bracket 3. I @ their Side walls 5 are, for example, symmetrical to the center plane of the chamber I openings 6 intended for two air filters 7. These two air filters 7 are through a shaft 8 or the like connected to one another and from a soap by means of a lever 9 adjustable together. Two stubs Io provided on the damping chamber I are for the guidance and storage of telescopically movable intake ports I I each with one Bushing I2 equipped. Rings I3 of circular cross-section made of elastic material are used for sealing and damping Storage of the intake ports I I in the damping chamber I. The intake ports I I are on the carburetor side pushed onto the connection I4 of the mixing chambers I5 and on this by means of Clamps 16 clamped.

Beim Ausbau der Vergaser werden die beiden Schellen I6 gelöst und die Ansaugstutzen II teleskopartig in die Dämpfungskammer I eingeschoben. Ein schmaler Bund 17 am vergaserseitigen Ende der Ansaugstutzen dient als Anschlag gegen die Büchsen 12 und begrenzt so den Einschubweg.When removing the carburettor, the two clamps I6 are loosened and the intake port II telescoped into the damping chamber I. A narrow one Collar 17 at the end of the intake manifold on the carburetor side serves as a stop against the Bushings 12 and so limits the insertion path.
