Description
Hinterradfederung für Fahrräder (Mountainbike, Trekking- und Citybikes)Rear suspension for bicycles (mountain bikes, trekking and city bikes)
Die Erfindung betrifftThe invention relates to
a) eine optimierte Anlenkung der Hinterradschwinge an voligefederten Fahrrädern (sogenannten Fullies)a) an optimized linkage of the rear swing arm on full suspension bikes (so-called fullies)
b) eine verbesserte Ausnutzung der Stoßdämpfereigenschaften, insbesondere der von Luft (Gas)federetementenb) improved utilization of shock absorber properties, especially those of air (gas) spring elements
Die Erfindung wird in folgenden anhand einer Zeichnung /FIG) erläutert Die Figur zeigt einen herkömmlichen (handelsüblichen) Diamantrahmen 1.The invention is explained below with reference to a drawing (FIG). The figure shows a conventional (commercially available) diamond frame 1.
Die Hinterradschwinge 2 ist so ausgebildet dass der linke Schwingenarm 2' und der rechte Schwingenarm 2" unter dem Tretlagen 3 hindurch zum Schwingenlagerdrehpunkt 4 geführt wird, der im Abstand von vorzugsweise 60 +- mm über und ca. 100 +- 20 mm vor dem Tretlager 3 entfernt am Unterrohr angeordnet istThe rear swing arm 2 is designed in such a way that the left swing arm 2' and the right swing arm 2" are guided under the bottom bracket 3 to the swing arm pivot point 4, which is arranged on the down tube at a distance of preferably 60 +- mm above and approx. 100 +- 20 mm in front of the bottom bracket 3.
Damit ist zum einen die Behinderung des Kettenumwerfers ausgeschlossen, zum anderen ist durch die Absenkung der Schwingenarme 2' + 2" ein aufschlagen der Kette weitgehend verhindert. On the one hand, this prevents the derailleur from being obstructed, and on the other hand , the lowering of the swing arms 2' + 2" largely prevents the chain from hitting the frame.
Des weiteren kann die Sichelartige Konstruktion des Schwingenarms 2'+2" unter dem Tretlager 3 als Schutz der vorderen Kettenblattzähne genutzt werden.Furthermore, the sickle-like construction of the swing arm 2'+2" under the bottom bracket 3 can be used to protect the front chainring teeth.
Ein wichtiger Vorteil des Konstruktion ist die austauschbare untere Befestigung 5 des Feder-Dämpfer-Elementes 6 an dem Schwingenarm 2' 2" nahe dem Schwingenlagerdrehpunkt 4.An important advantage of the design is the replaceable lower attachment 5 of the spring-damper element 6 on the swing arm 2'2" near the swing arm pivot point 4.
Beim Einfedern des Hinterradschwinge wird der Dämpfer 6 sozusagen doppelt komprimiert.When the rear swing arm is compressed, the damper 6 is , so to speak, doubly compressed.
1) durch den Hebel 7 welcher die Hauptarbeit verrichtet1) by lever 7 which does the main work
2) durch die Anlenkung der Befestigung 52) by the articulation of the fastening 5
D.h. es wirken zwei Drehmomente auf die Hinterradschwinge. Das Hauptdrehmoment überträgt Hebel 7, Das Nebendrehmoment (ca. 1/4 des Hauptdrehmomentes) wirkt direkt über Befestigung 5 auf die Hinterradschwinge. Folge - Progressive Federkennlinie, dadurch kann der Dämpfer mit weniger Gasdruck betrieben werden. Bei Stahlfedersystem analog geringere Federrate.This means that two torques act on the rear swing arm. The main torque is transmitted by lever 7. The secondary torque (approx. 1/4 of the main torque) acts directly on the rear swing arm via fastening 5. Result - progressive spring characteristic, which means that the shock absorber can be operated with less gas pressure . With a steel spring system, the spring rate is similarly lower.
