Description

Die Erfindung bezieht sich auf eine federnde Lagerung des Hinterrades für Fahrräder, Motorräder u. dgl.The invention relates to a resilient mounting of the rear wheel for bicycles, motorcycles, etc.

Bekannt sind Hi-nterradfederungen, bei denen das Hinterrad in einer Schwinggabel gelagert ist, die am Rahmen drehbar angeordnet und gegen diese durch eine Federung abgestützt ist. Diese Federung hat den Nachteil, daß die Gabel beim Fahren starken Verwindungskräften ausgesetzt ist, die sich nachteilig auf die Gabelanlenkung am Rahmen aus--,virken. Gleichzeitig besteht die Gefahr, daß durch die Gabelverwindung eine schiefe Stellung des Hinterrades eintritt.Rear wheel suspension systems are known in which the rear wheel is in one Vibration fork is mounted, which is rotatably arranged on the frame and against this through a suspension is supported. This suspension has the disadvantage that the fork when Driving is exposed to strong torsional forces, which are detrimental to the fork linkage on the frame -, virken. At the same time there is the risk that the fork twisting an inclined position of the rear wheel occurs.

Die Erfindung bezweckt die Beseitigung dieser Nachteile dadurch, daß statt der einfachen Gabel eine Doppelgabel verwandt wird, deren Enden an der Lagerung am Rahmen und am Lager des Hinterrades zusammenlaufen. Dadurch erhält die Gabel eine Versteifung, die Verwindungen ausschließt. Zur weiteren Erhöhung der Steifheit wird das untere Führungsrohr der an sich bekannten Federung mit den vier Gabelarmen fest verbunden.The invention aims to eliminate these disadvantages in that instead of the simple fork a double fork is used, the ends of which are attached to the bearing converge on the frame and the bearing of the rear wheel. This gives the fork a stiffening that eliminates twisting. To further increase the rigidity becomes the lower guide tube of the suspension system known per se with the four fork arms firmly connected.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigt Abb. i ein Fahrrad mit der angebauten Schwinggabelfederung, Abb. 2 eine Ansicht der Schwinggabel, Abb. 3 eine Draufsicht und Abb. d. einen Schnitt durch die Federung in vergrößertem Maßstab.In the drawing, the invention is shown in one embodiment. It shows Fig. I a bicycle with the attached tuning fork suspension, Fig. 2 a View of the tuning fork, Fig. 3 a plan view and Fig. D. a cut through the suspension on an enlarged scale.

Die Schwinggabel besteht aus zwei oberen Gabelarmen i und zwei unteren Gabelarmen ?, die durch das untere Führungsrohr der Feder verbunden sind. Die Gabelarme sind an einem Ende paarweise verbunden, wodurch das Lager .1 für die Anlenkung 15 atn Fahrradrahmen entsteht. Die anderen Enden der beiden Gabeln sind ebenfalls zusammengeführt und bilden die Lagerung 14 für die Hinterradachse. In der Nähe des Rahmenlagers sind die oberen Gabelschenkel i durch einen Versteifungssteg 12 verbunden. Die untere Führungsbuchse 3 der Federung ist zwischen den Gabelpaaren i und 2 eingeschweißt und enthält die Schraubenfeder 7, die durch einen Querstift 5 am unteren Ende gehalten ist. In der unteren Buchse 3 ist die obere Buche 6 geführt, die das obere Ende der Feder 7 aufnimmt. Das obere Ende 8 der Buchse 6 ist gabelförinig ausgebildet und trägt zwei Bohrungen g: die mit einer am Sattelstützrohr i i befestigten Buchse i o die Lagerung der Federung am Rahmen bilden. An der oberen Gabel i können Laschen 13 für die Befestigung eines Gepäckträgers vorgesehen sein.The tuning fork consists of two upper fork arms i and two lower ones Fork arms? Which are connected by the lower guide tube of the spring. The fork arms are connected in pairs at one end, so that the bearing .1 for the linkage 15 atn bicycle frame is created. The other ends of the two forks are also brought together and form the bearing 14 for the rear wheel axle. Near the frame warehouse the upper fork legs i are connected by a stiffening web 12. The lower one Guide bush 3 of the suspension is welded between the fork pairs i and 2 and contains the coil spring 7 held by a transverse pin 5 at the lower end is. In the lower socket 3, the upper beech 6 is guided, which is the upper end of the Spring 7 picks up. The upper end 8 of the socket 6 is fork-shaped and carries two bores g: the one with a socket attached to the seat post i i i o form the mounting of the suspension on the frame. There can be tabs on the upper fork i 13 can be provided for attaching a luggage rack.
