Description
Die Erfindung bezieht sich auf Motorräder, insbesondere Leichtmotorräder oder Motorfahrräder, bei denen das Rahmenrohr zum Ableiten der Auspuffgase und zum Schalldämpfen verwendet wird. Derartige Motorräder sind bereits bekannt, haben aber den Nachteil, daß nur ein Teil des Rohrrahmens zum Ableiten der Auspuffgase und zum Schalldämpfen benutzt wird, der aber ungenügend ist. Außerdem war bei diesen bekannten Motorrädern der Rohranschluß zwischen Motor und Abgasleitung nicht so ausgebildet, daß eine Einstellung des Antriebsmotors in der Fahrtrichtung zwecks Nachstellung der Treibketten möglich war.The invention relates to motorcycles, in particular light motorcycles or motorcycles, where the frame tube is used to divert the exhaust gases and for soundproofing. Such motorcycles are already known, but have the disadvantage that only part of the pipe frame for discharging the exhaust gases and for Soundproofing is used, but this is insufficient. In addition, this was known Motorcycles the pipe connection between the engine and the exhaust pipe is not designed in such a way that an adjustment of the drive motor in the direction of travel for the purpose of readjusting the Driving chains was possible.
Durch den Gegenstand der Erfindung sollen die den bekannten Motorrädern anhaftenden Nachteile dadurch behoben werden, daß der Auspuffgasstrom geteilt durch den gesamten Hohlraum des Rohrrahmens geleitet wird, wodurch ein sehr erheblicher und vorteilhafter Ausdehnungsraum und" große Abkühlungsflächen für die wirksame und zweckmäßige Schalldämpfung und Ableitung der Auspuffgase geschaffen werden. Außerdem ist der Rohranschluß zwischen Antriebsmotor und Abgasleitung so eingerichtet, daß eine Einstellung des-Motors gegenüber dem Rahmen in der Fahrtrichtung und dadurch eine für die beiden hier vorhandenen Treibketten o. dgl. etwa notwendig werdende ungleiche Nachstellung ermöglicht wird.The object of the invention is intended to adhere to the known motorcycles Disadvantages are eliminated in that the exhaust gas flow is divided by the total Cavity of the tubular frame is passed, creating a very significant and beneficial Expansion space and "large cooling surfaces for the effective and appropriate soundproofing and dissipation of the Exhaust gases are created. In addition, the pipe connection is between the drive motor and exhaust pipe arranged so that an adjustment of the engine relative to the frame in the direction of travel and thus one for the two drive chains present here o. The like. Any unequal readjustment that may become necessary is made possible.
Die Erfindung ist als ein Ausführungsbeispiel in der Zeichnung in Seitenansicht dargestellt. The invention is shown as an embodiment in the drawing in side view.
In bekannter Weise besteht das Motorrad im wesentlichen aus den Läufrädern 1 und 2 und dem Rahmen 3, der aus zusammengesetzten Rohren, also aus einem Hohlkörper besteht. Der Antriebsmotor 4 ist in einer Brücke 5 gelagert und am Auspuff flansch 6 mit einem Rohrstück 7 versehen, das in ein am Rahmenrohr 3 befestigtes Rohrstück 8 greift. Um die Verstellung oder das leichte Ausbauen des Antriebsmotors zu gestatten, ist zwischen den Rohrstücken 7 und 8 ein Zwischenraum gelassen. Zur Verbindung beider Rohrstücke miteinander dienen in bekannter Weise Spannbänder o. dgl. Die vom Kolben ausgestoßenen Auspuffgase werden in Pfeilrichtung A durch die kurzen Rohrstücke 7 und 8 gepreßt und entweichen in den Pfeilrichtungen B, C und D. In der Zeichnung ist das Rahmenrohr 31 unterhalb des Tretkurbellägers 9 angeordnet, wie es für Rahmenneukonstruktionen vorgesehen ist. Das Rahmenrohr 31 kann aber auch beliebig am Tretkurbellager angebracht werden, und es kann jedes bereits vorhandene Fahrzeug erfindungsgemäß umgebaut werden.In a known manner, the motorcycle consists essentially of the running wheels 1 and 2 and the frame 3, which consists of composite tubes, that is, of a hollow body. The drive motor 4 is mounted in a bridge 5 and provided on the exhaust flange 6 with a pipe section 7 which engages in a pipe section 8 attached to the frame tube 3. In order to allow the drive motor to be adjusted or easily removed, a gap is left between the pipe sections 7 and 8. Tensioning straps or the like are used to connect the two pipe sections together in a known manner. The exhaust gases expelled by the piston are pressed in the direction of arrow A through the short pipe sections 7 and 8 and escape in the directions of arrows B, C and D. In the drawing, the frame tube 3 1 arranged below the pedal crank bearing 9, as is provided for frame new constructions. The frame tube 3 1 can, however, also be attached to the pedal crank as desired, and any existing vehicle can be converted according to the invention.
