Description

Bei Fahrradmotoren ist man trotz verhältnismäßig höherer Leistungen darauf bedacht, • die Abmessungen möglichts gering zu halten und den ganzen Aufbau ohne Einbuße des Wirkungsgrades gedrängt zu gestalten.In the case of bicycle motors, despite their relatively higher performance, one is careful to • to keep the dimensions as small as possible and the entire structure without sacrificing the To make efficiency rushed.

Die vorliegende Erfindung hat einen Auspufftopf mit Luftansauger an Fahrradmotoren zum Gegenstand, welcher diesem Zweck besonders dienlich ist. Gemäß der Erfindung ist der Auspufftopf mit dem Ansaugrohr zu einer Einheit verbunden, derart, daß die Frischluft durch den Auspufftopf hindurch angesaugt wird, der an der, Vorderseite einen Luftfangtrichter und eine in der Achse des Topfes verlaufende Luftleitung besitzt. Dadurch wird der Auspufftopf wirksam gekühlt und das gesamte Wärmegefälle vergrößert. Nebenbei erfährt auch die Ansaugluft eine Vorwärmung, welche an sich nicht neu ist. Die Vereinigung von Auspufftopf und Ansaugrohr ergeben einen einheitlichen Aufbau des Motors, indem Vergaser, Ansaugrohr, Auspuffrohr und Auspufitopf sämtlich in der in.der Fahrtrichtung liegenden Mittelas ebene angebracht sein können.The present invention has an air intake muffler on bicycle engines to the object which is particularly useful for this purpose. According to the invention the muffler is connected to the intake pipe to form a unit, such that the fresh air is sucked in through the muffler on the front has an air collecting funnel and an air line running in the axis of the pot. This effectively cools the muffler and increases the overall heat gradient. In addition, the intake air is also preheated, which in itself is not new. The muffler union and intake pipe result in a uniform structure of the engine, in that the carburetor, intake pipe, The exhaust pipe and muffler are all in the middle in the direction of travel level can be attached.

Der Erfindungsgegenstand ist auf der Zeichnung dargestellt.The subject of the invention is shown in the drawing.

Abb. 2' eine Gesamtansicht der Anordnung an einem Motorrade veranschaulicht.Fig. 2 'illustrates an overall view of the arrangement on a motorcycle.

Das Auspuffrohr« befindet sich vorn am Motor b, der Vergaser c hinter dem Motor. An den Vergaser schließt sich das Ansaugrohr d an, welches sich allmählich nach vorn in den Auffangtrichter e erweitert. Dieser Trichter ist innerhalb des Auspufftopfes f untergebracht. Vergaser, Ansaugrohr, Auspuffrohr und Auspufftopf liegen sämtlich in der Mittelebene des Rades. Bei der Fahrt dringt die Luft durch den Trichter e in das Ansaugrohr und in den Vergaser ein. Da der Auffangtrichter in den Auspufftopf eingebaut ist, werden die Auspuffgase stark abgekühlt und dadurch das Wärmegefälle vergrößert. Der Auffangtrichter ist vorn durch ein Luftfilter abgeschlossen.The exhaust pipe «is at the front of the engine b, the carburetor c behind the engine. The intake pipe d connects to the carburettor and gradually widens forward into the collecting funnel e . This funnel is housed inside the muffler f. The carburetor, intake pipe, exhaust pipe and muffler all lie in the center plane of the wheel. When driving, the air penetrates through the funnel e into the intake pipe and into the carburetor. Since the collecting funnel is built into the muffler, the exhaust gases are cooled down considerably, thereby increasing the heat gradient. The collecting funnel is closed at the front by an air filter.

Der Gesamtaufbau ergibt ein geschlossenes gefälliges Ganzes, welches sich in den Fahrradrahmen leicht einfügt und nach den Seiten nicht ausbaut.The overall structure results in a closed, pleasing whole, which is integrated into the bicycle frame Easily inserts and does not expand on the sides.
