Description
Federungsvorrichtung für das Vorderrad von Fahrrädern, Motorrädern u. dgl. Es ist bekannt, das Vor:derrad von Fahrrädern, Motorrädern u. dgl., mit einer Federungsvorrichtung zu versehen, welche aus einem U-förmig gebogenen, die Radachse tragenden Schwinghebel besteht, der mit an den Gabelarmen hängenden Federbüchsen verbunden ist. Hierbei ist aber bei auftretenden starken Seitendrücken und scharfen Kurvenfahrten das gefährliche Anschleifen des Rades an der Fahrra@dgab(2l nicht zu vermeiden, weil niemals der lang geführte Schwinghebelbolzen so genau bearbeitet bzw. ,montiert ist, daß er diesen Seitendrücken Rechnung trägt.Suspension device for the front wheel of bicycles, motorcycles It is known that the front wheel of bicycles, motorcycles and the like, with to provide a suspension device, which consists of a U-shaped bent, the The rocker arm carrying the wheel axle consists of the spring bushes hanging on the fork arms connected is. Here, however, is when strong side pressures and sharp Cornering, the dangerous grinding of the wheel on the bicycle (2l not to be avoided, because the long rocker arm bolt never machined so precisely or, is mounted that it takes these side pressures into account.
Der Erfindungsgegenstand beseitigt diese Übelstände dadurch, @daß die zur Lagerung der an den Wangen des Schwinghebels angesetzten Drehzapfen dienenden Hülsen in den Schlitzen .am Ende der Gabelarme befestigt sind.The subject of the invention eliminates these evils by @ that those used to support the pivot pins attached to the cheeks of the rocker arm Sleeves are attached in the slots at the end of the fork arms.
In der Zeichnung .ist eine Ausführungsform des Erfindungsgegenstandes in Abb. i schaubildlich dargestellt, während Albb. 2 in vergrößertem Maßstäbe auseinandergezogen die Verbindung der die Gabelenden tragenden Hülsen auf dem Tragzapfen veranschaulicht.In the drawing .is an embodiment of the subject matter of the invention shown diagrammatically in Fig. i, while Albb. 2 pulled apart on an enlarged scale illustrates the connection of the sleeves carrying the fork ends on the trunnion.
Der an die Federbüchsen i, 2 angelenkte und auf der Fahrradachse 3 befestigte Schwinghebel 4, welcher zweckmäßig als Bügel ausgebildet ist, trägt seitlich Zapfen 5, die in der von den Gabelenden 6 gehaltenen und durch Muttern daran befestilgtenHülsen7 gelagert sind. Die mit Gewinde g versehenen Zapfen 5 tragen, ohne ihre Drehbarkeit in den Hülsen 7 zu verlieren, je eine Mutter und Gegenmutter B. Jede Hülse 7 ist mit einem Ausnehmungen io tragenden Kopf ii versehen, die in die korrespondierenden Schlitze der Gabelenden 6 hineinpassen. In der Bohrung der Hülsen 7 ist am Kopfende eine konische Ausfräsung vorgesehen, welche auf eine entsprechende konische Verdickung 12 des Zapfens 5 paßt.The one hinged to the spring bushes i, 2 and on the bicycle axle 3 attached rocker arm 4, which is expediently designed as a bracket, carries laterally Pins 5, which are held in the sleeves 7 held by the fork ends 6 and fastened to them by nuts are stored. The threaded pin 5 carry g without their rotatability To lose in the sleeves 7, one nut and one lock nut B. Each sleeve 7 is provided with a recesses io carrying head ii, which in the corresponding Fit the slots in the fork ends 6. In the bore of the sleeves 7 is at the head end a conical cutout provided, which on a corresponding conical thickening 12 of the pin 5 fits.
Hierdurch sind die mittels Mutter und Gegenmutter 8 .gegen achsiale Verschiebung gesicherten Zapfen 5 in den Hülsen 7 frei beweglich.This means that the nut and counter nut 8. Against axial Displacement secured pin 5 in the sleeves 7 freely movable.
Der Schwinghebel4 kann mit einer beliebigen Anzahl Löcher 13, die nebeneinander angeordnet sind, versehen sein, in welchen die Kolbenstangen 16 der Federbüchsen i, 2 je nach Zweckmäßigkeit befestigt werden können. Außerdem können die in den Büchsen i, 2 angeordneten Federn regelbar sein. Es kann dies, wie die Zeichnung zeigt, in der Weise erfolgen, daß über den die Federn 14, 15 tragenden Stangen 16 eine Außengewinde besitzende Hülse 17 angeordnet ist, die in das Muttergewinde 18 der Federbüchsen i, 2 einschraubbar ist. Eine über die Hülse 17 geschraubte Mutter i9 dient als Begrenzung und Gegenmutter der Verschraubung.The rocker arm 4 can have any number of holes 13 that are arranged side by side, be provided in which the piston rods 16 of the Spring bushes i, 2 can be attached depending on the expediency. Also can the springs arranged in the bushes i, 2 can be regulated. It can do this, like that Drawing shows, done in such a way that over the springs 14, 15 supporting Rods 16 an externally threaded sleeve 17 is arranged, which in the nut thread 18 of the spring sleeves i, 2 can be screwed in. A nut screwed over the sleeve 17 i9 serves as a limitation and lock nut for the screw connection.
Die als besonders günstig zu bezeichnenden Konstruktionen der vorgenannten Teile sind natürlich belanglos für die Erfindung, welche lediglich darin besteht, daß die zur Lagerune; der an den Wangen des Schwinghebels 4 angesetzten Drehzapfen 5 dienenden Hülsen 7 in den Schlitzen am Ende- der Gabelarme 6 befestigt sind.The constructions of the aforementioned which can be described as particularly favorable Parts are of course irrelevant to the invention, which only consists in that they go to the warehouse; the pivot pin attached to the cheeks of the rocker arm 4 5 serving sleeves 7 are fastened in the slots at the end of the fork arms 6.
