Description

Das Zusatzpatent 903 180 zum Hauptpatent 880 7i2 betrifft einen gegossenen Fahrradrahmen aus Leichtmetall, bei dem der vorzugsweise alshohler Flachkörper ausgebildete Hauptrahmenträger einschließlich des von diesem im spitzen Winkel abzweigenden Sattelstützrohres, des Tretlagerrohres und des Lenkkopfes aus einem in der Kokille gegossenen oder gespritzten Stück bestellt. An das Sattelstützrohr schließt sich, ebenfalls angegossen, eine nach unten und hinten offene Tasche an, deren oberer Abschluß vorzugsweise als Gepäckträger ausgebildet ist. Bei Verwendung eines um das Tretlagerrohr schwenkbaren, das Hinterrad tragenden Kettenkastens wird der letztere an der oberen Abschlußplatte der Tasche bzw. am Gepäckträger federnd abgestützt.The additional patent 903 180 to the main patent 880 7i2 relates to a cast bicycle frame made of light metal, in which the main frame support, which is preferably designed as a hollow flat body, including the saddle support tube branching off at an acute angle, the bottom bracket tube and the steering head is ordered from a piece cast or injection-molded in the mold. A pocket, which is open at the bottom and at the rear and is also molded, connects to the seat post tube, the upper end of which is preferably designed as a luggage rack. When using a chain case pivotable about the bottom bracket tube and carrying the rear wheel, the latter is resiliently supported on the upper end plate of the bag or on the luggage rack.

Die Erfindung betrifft eine `'Weiterentwicklung des Gegenstandes des Zusatzpatents. Für die Verwendung des Rahmens als Motorradrahmen soll eine konstruktiv und- festigkeitsmäßig günstige Anbringung des Motorgetriebeblocks geschaffen werden. Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß die untere Gußkernöffnung des als hohler Flachkörper ausgebildeten, vorzugsweise in. der Kokille gegossenen Rahmens bei dessen Verwendung als Motorradrahmen durch den angeschraubten Motorgetriebeblock abgeschlossen ist.The invention relates to a '' further development of the subject matter of Additional patents. For the use of the frame as a motorcycle frame, one should constructively and- favorable attachment of the engine transmission block in terms of strength can be created. The inventive solution to this problem is that the lower cast core opening of the formed as a hollow flat body, preferably cast in. The mold Frame when used as a motorcycle frame through the screwed-on engine transmission block is completed.

Durch eine derartige Anordnung des Motorgetriebeblocks am Rahmen werden zwei wesentliche Vorteile erreicht. Einmal ist dadurch der Festigkeitsverband des Rahmens gewährleistet, und zum anderen ist eine Verschmutzung des durch den Rahmenkörper eingeschlossenen Hohlraumes ausgeschlossen.Such an arrangement of the engine transmission block on the frame achieved two main advantages. On the one hand, this creates the strength association of the Guaranteed frame, and on the other hand is a contamination of the frame body enclosed cavity excluded.

:Dach einem weiteren Merkmal der Erfindung wird in dem Hohlraum des Hauptrahmenträ.gers der mit dem Getriebegehäuse in einem Stück gegossene oder an das Gehäuse, angeschraubte Brennstoffbehälter untergebracht.: Another feature of the invention is in the cavity of the roof Hauptrahmenträ.gers, which is cast in one piece with the gearbox housing or is attached to it the housing, screwed fuel container housed.

In der Abbildung ist ein Ausführungsbei,spiel des Erfindungsgegenstandes dargestellt. Mit i ist das Vorder- und mit 2 das Hinterrad bezeichnet. Im Lenkkopf- des Hauptrahmenträgers 3 ist der Lenker4 gelagert. Auf dem rechten, als Sattelstütze ausgebildeten. Arm des V-förmigen Rahmens ist der Sattel 5 angeordnet. Die Sattelstütze ist nach dem Hinterrad zu ausladend als Gepäckträger 6 ausgebildet. Die Federung des Vorderrades ist dadurch gewährleistet, daß am Vorderradgabelrohr 7 ein Doppelhebel 8 schwenkbar gelagert ist, dessen einer Arm das Vorderrad i trägt und dessen anderer Arm mittels der Gummizugfeder g am Gabelrohr 7 aufgehängt ist.In the figure is a Ausführungsbei, game of the subject invention shown. The front wheel is designated by i and the rear wheel by 2. In the steering head of the main frame support 3, the handlebar 4 is mounted. On the right, as a seat post trained. The saddle 5 is arranged on the arm of the V-shaped frame. The seat post is designed as a luggage rack 6 too expansive after the rear wheel. The suspension the front wheel is ensured by the fact that a double lever on the front fork tube 7 8 is pivotally mounted, one arm of which carries the front wheel i and the other Arm is suspended from the fork tube 7 by means of the elastic tension spring g.

Mit io ist der Motorgetriebeblock und mit ii sind die Zylinder bezeichnet. Um die Lagerung der Tretkurbeln 14 ist der das Hinterrad 2 tragende Kettenkasten i2 schwenkbar gelagert und gegen den Gepäckträger 6 mittels des Teleskopfederrohres 13 federnd abgestützt. Der Brennstoffbehälter 1s ist entweder mit dem Getriebegehäuse io aus einem Stück gegossen oder auf dieses aufgeschraubt. Der Behälter ragt in den nach unten durch das angeflanschte Getriebegehäuse i o abgeschlossenen. Hohlraum des Rahmens 3 hinein. Am Rücken des Hauptrahmenträgers 3 befindet sich die Einfüllverschraubung 16 des Brennstoffbehälters 1s. Mit 17 sind die Schrauben bezeichnet, die den Motorgetriebeblock io am Rahmen 3 befestigen.The engine transmission block is denoted by io and the cylinders are denoted by ii. The chain case carrying the rear wheel 2 is used to support the cranks 14 i2 pivotally mounted and against the luggage rack 6 by means of the telescopic spring tube 13 resiliently supported. The fuel tank 1s is either with the gearbox io cast from one piece or screwed onto it. The container protrudes in which is closed off at the bottom by the flange-mounted gear housing i o. cavity of frame 3 into it. The filler fitting is located on the back of the main frame support 3 16 of the fuel tank 1s. With 17 the screws are designated, which the engine gearbox block Attach io to frame 3.
