Description

Bei den Geschwindigkeitswechselgetrieben mit Kettenumschaltung, insbesondere für Fahrräder, ist der Umschaltvorgang von einem gewissen Flattern der Kette begleitet. Die den Gegenstand der Erfindung bildende soll ein Abspringen d'er Kette an der Auflaufstelle der Kette auf das Antriebskettenrad verhindern.In the case of speed change transmissions with chain switching, in particular for bicycles, the switching process is accompanied by a certain amount of chain flutter. The subject of the invention is intended to jump off d'er chain on the Prevent the chain from running into the drive sprocket.

Abb. i zeigt die Kettenführung i, die parallel zu dem Antriebskettenrad 2 liegt. Die Führung i hat cirie geeignete Länge, um Reibungen der Kette 3 oben oder unten bei 4 und 5 hei Flatterbewegungen in der Höhenrichtung zu vermeiden.Fig. I shows the chain guide i, which is parallel to the drive sprocket 2 lies. The guide i has cirie suitable length to avoid friction of the chain 3 above or at 4 and 5 at the bottom to avoid fluttering in the vertical direction.

Die Teile 4 und 5 können übrigens mit einem geeigneten -Material überzogen sein, «-elches die gel1gentlichen Stöße möglichst geräuschlos machen soll. Das Abspringen der Kette durch die seitliche Verschiebung derselben beim Umschalten ist durch zwei Wangen 6 und 7 (Abb. 2) unmöglich gemacht, welche die Kette 3 zwingen, auf das Antriebskettenrad -2 ausgerichtet zu bleiben.The parts 4 and 5 can also be coated with a suitable material be, "-which should make the occasional jolts as noiseless as possible. The jumping off the chain through the lateral displacement of the same when switching is through two Cheeks 6 and 7 (Fig. 2) made impossible, which force the chain 3 onto the drive sprocket -2 to stay aligned.

Die Kettenführung i ist an einer geeigneten Stelle durch ein bekanntes Mittel befestigt, z. B. durch die Schelle 8 mit Klemmschraube 9, was die Einstellung ihrer Höhe entsprechend dein Durchmesser des Antriebslcettenrades 2 gestattet. Der Teil io gleitet in einer Gleitschiene i i, damit die Anordnung auf das Kettenrad 2 (Abb. 2) eingestellt «-erden kann. Zur hinstellung oder Befestigung mit dieser Kettenführung zusammen kann jedes andere bekannte System benutzt werden.The chain guide i is attached to a suitable location by a known means, e.g. B. by the clamp 8 with clamping screw 9, which allows the adjustment of its height according to your diameter of the drive chain wheel 2. The part io slides in a slide rail ii so that the arrangement can be adjusted to the chain wheel 2 (Fig. 2). Any other known system can be used for positioning or fastening with this chain guide.

`Venn mehrere abgestufte Antriebskettenräder mit verschiedenen Durchmessern vorhanden sind, kann die Kettenführung dazu benutzt werden, die Kette auf das gerade in Eingriff befindliche Kettenrad ausgerichtet zu halten. Der Teil io ist dann mit einer f-lintindlierschaltvorrichtung verbunden,welche die Unischaltung der Kette und den Wechsel des An triebskettenrades gestattet, ohne daß die Kette wäh- rend des Umschaltens abspringt. Die Kettenführung kann vollständig oder teilweise mit einem geräusch- dämpfenden Überzug versehen «erden, z. B. einem gummihaltigen oder aus einem plastischen Werk- stoff bestehenden Erzeugnis. Zur Ermöglichung eines leichten Ein- und Aus- balls des S\'stenls können die Wangen 6 und 7 durch eine oder mehrere Schrauben miteinander verbunden werden, z. B. Schrauben 1 2 mit Abstandsstücken 13, welche einen geräuscli(läinpfeiT(1ci1 Leberzug haben oder nicht. If there are multiple stepped drive sprockets of different diameters, the chain guide can be used to keep the chain aligned with the sprocket being engaged. The part io is then connected to a f-lintindlierschaltungvorrichtung, which allows the uninhibition of the chain and the change of the drive chain wheel without the chain selecting rend of switching. The chain guide can be completely or partially with a noisy provided with damping coating «earth, z. B. a rubber-based or made of a plastic work- substance existing product. To enable easy on and off The balls of the S \ 'stenl can go through the cheeks 6 and 7 one or more screws connected together be e.g. B. Screws 1 2 with spacers 13, which have a noisy whistle (1ci1 liver train or not.
