Description

Rahmen aus gepreßten Blechteilen für Fahrräder, Motorfahrräder, Kleinkrafträder u. dgl. Es sind bereits Rahmen aus gepreßten Blechteilen für Fahrräder, Motorfahrräder, Kleinkrafträder u. dgl. mit einem aus zwei spiegelbildlichen miteinander fest verbundenen Hälften bestehenden durchgehenden Hauptträger vorgeschlagen worden, der, vom Steuerkopf ausgehend, sich zur Hinterradlagerung hin gabelt. Ein Nebenträger durchsetzt den Hauptträger und ist mit diesem fest verbunden. An dem Nebenträger sitzt oben der Sattel. Unten ist an dem Nebenträger die Treteinrichtung bzw. der Motor mit dem Getriebe gehaltert.Frame made of pressed sheet metal parts for bicycles, motorcycles, mopeds and the like. There are already frames made of pressed sheet metal parts for bicycles, motorcycles, Small motorcycles and the like with one of two mirror images firmly connected to one another Halves existing through main beam has been proposed, the one from the steering head starting, forks towards the rear wheel bearing. A secondary beam penetrates the Main beam and is firmly connected to this. At the top of the secondary beam sits the Saddle. At the bottom of the secondary beam is the pedal device or the motor with the Gearbox supported.

Der Erfindung liegt die Aufgabe zugrunde, bei derartigen Fahrzeugen das Hinterrad an einer Schwinge zu befestigen, die durch eine oder mehrere Federn gegenüber dem Rahmen abgestützt ist.The invention is based on the object in such vehicles to attach the rear wheel to a swing arm, which is supported by one or more springs is supported against the frame.

Die Erfindung besteht darin, daß die Gabelenden des durchgehenden Hauptträgers in etwa senkrecht verlaufende Hohlkörper übergehen, in denen eine schwingungsdämpfende Einrichtung zum Abstützen einer am Rahmen angelenkten, das Hinterrad tragenden Schwinge vorgesehen ist.The invention consists in that the fork ends of the continuous Main support in approximately vertically extending hollow body, in which a vibration-damping Device for supporting a swing arm articulated to the frame and bearing the rear wheel is provided.

Es sind bereits federnde bzw. stoßdämpferartig wirkende Halterungen für die das Hinterrad tragende Schwinge bekannt, Diese bekannten Ausführungsformen benötigen jedoch besondere Verstrebungen nach oben und unten, um den ausreichenden Halt für die schwingungsdämpfende Einrichtung zu schaffen. Solche besonderen Halterungen sind, bei der Ausführungsform nach der Erfindung nicht erforderlich.There are already resilient or shock absorber-like brackets known for the swing arm carrying the rear wheel, these known embodiments however, need special bracing up and down in order to achieve the adequate To provide support for the vibration damping device. Such special mounts are not required in the embodiment according to the invention.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung wiedergegeben und wird im folgenden beschrieben Abb. 1 zeigt eine Seitenansicht.An embodiment of the invention is shown in the drawing and will be described below. Fig. 1 shows a side view.

Abb. 2 zeigt die Ansicht von oben mit Schnitt A-B durch die Sattelstütze, und Abb. 3 zeigt die Schwingen- und Federungsanordnung teilweise im Schnitt nach Abb. 1 im belasteten Zustand.Fig. 2 shows the view from above with section A-B through the seat post, and Fig. 3 shows the rocker and suspension arrangement partly in section Fig. 1 in the loaded state.

Es bedeuten: 1 den Hauptträger, 2 das Hintergabelteil, 3 die Schwinge, 4 den Drehpunkt der Schwinge, 5 den senkrecht verlaufenden Hohlkörper des Hauptträgers, 6 das Stoßdämpferrohr, 7 den Kolben, 8 die Kolbenstange, 9 die Feder, 10 den Anlenkungspunkt für die Kolbenstange, 11 den unteren Federteller, 12 den oberen Federteller, 13 den Verbindungspunkt für Schwinge und Federungsanordnung, 14 die Federung im entlasteten Zustand, 15 den Anfang der Aussparung, 16 das Ende der Aussparung des Hauptträgers, 17 das Hinterradschutzblech, 18 das Hinterrad, 19 den oberen Abschluß des Hohlkörpers und 20 die Stütze für das Hinterradschutzblech.It means: 1 the main beam, 2 the rear fork part, 3 the swing arm, 4 the pivot point of the rocker arm, 5 the vertical hollow body of the main beam, 6 the shock absorber tube, 7 the piston, 8 the piston rod, 9 the spring, 10 the articulation point for the piston rod, 11 the lower spring plate, 12 the upper spring plate, 13 the connection point for the swing arm and suspension arrangement, 14 the suspension in the unloaded State, 15 the beginning of the recess, 16 the end of the recess of the main beam, 17 the rear fender, 18 the rear wheel, 19 the upper end of the hollow body and 20 the support for the rear fender.

Die Federungsanordnung geht aus folgendem hervor: Bei Belastung des Fahrzeuges durch den Fahrer werden die beiden Hohlkörper 5 der Hintergabelteile 2 nach unten bewegt und die Federn 9 zusammengedrückt, wobei der Stoßdämpferkolben infolge der Anlenkung der Kolbenstange 8 am oberen Abschluß 19 diese Bewegungen mitmacht und die Federung dämpft. Die Schwinge 3 wird mit dem einen Ende am unteren, für die Motoraufhängung vorgesehenen Rahmenteil befestigt, während sie mit dem anderen Ende mit der Federung verbunden wird und die Hinterradachse aufnimmt. Die Schwinge beschreibt mit ihrem hinteren Teil einen Kreisbogen um den Drehpunkt 4. Zum Ausgleich der dabei auftretenden Längendifferenz wird die Kolbenstange 8 an ihrem oberen Ende etwas nachgiebig am Teil 19 gelagert.The suspension arrangement can be seen from the following: When the When the vehicle is driven by the driver, the two hollow bodies 5 of the rear fork parts become 2 moved down and the springs 9 compressed, the shock absorber piston as a result of the articulation of the piston rod 8 on the upper end 19, these movements join in and dampen the suspension. One end of the rocker 3 is attached to the lower, attached to the frame part provided for the engine suspension, while it is attached to the other End is connected to the suspension and receives the rear axle. The swing arm describes with its rear part an arc around the pivot point 4. To compensate the resulting difference in length is the piston rod 8 at its upper end mounted somewhat resiliently on part 19.
