Abstract
Diese Art der Schaltung ermöglicht eine erhebliche Erleichterung für den Fahrradfahrer.
Durch die große Bandbreite der Übersetzung ist es möglich alle Herausforderungen bezüglich Geschwindigkeit und Steigfähigkeit zu meistern. Sie nimmt auch keinen extra Platz weg da eh ein Rahmen verbaut werden muß, lediglich ein bisschen breiter. Des weiteren spart die Schaltung Kosten für Kette, Zahnräder und Montage durch immer gerade laufende Kette. Es gibt auch keine Doppelgänge wie sie bei normalen Kettenschaltungen entstehen.
This type of gearshift makes things much easier for the cyclist.
The wide gear range makes it possible to master all challenges regarding speed and climbing ability. It also doesn't take up any extra space, since a frame is required anyway; it's just a bit wider. Furthermore, the gear system saves costs for the chain, sprockets, and assembly because the chain always runs straight. There are also no double gears like those found with conventional derailleur systems.
Description
Die Erfindung betrifft ein Liegefahrrad wo die Schaltung vorne im Rahmen verbaut werden kann. Der hintere auf den Reifenantrieb verbleibende Kettenstrang kann dadurch viel einfacher ohne Schaltstufen erfolgen.The invention relates to a recumbent bicycle where the gears can be installed at the front of the frame. The chain strand remaining on the rear wheel drive can thus be shifted much more easily without gear steps.
Durch diese Erfindung ist es möglich eine viel größere Bandbreite an Gängen zu haben ohne Überschneidungen.This invention makes it possible to have a much wider range of gears without overlap.
Und was eigentlich das wichtigste an dieser Erfindung ist, das man einen Geschwindigkeitsbereich bei Velomobilen abdecken kann wo bisher nicht möglich war ohne großen Aufwand oder Reibungsverlusten durch Getriebeübersetzungen.And what is actually the most important thing about this invention is that you can cover a speed range in velomobiles that was previously not possible without great effort or friction losses due to gear ratios.
Rechnen sie sich das Übersetzungsverhältnis aus bei 11/46 zu 46/11 und die Endübersetzung auf das Hinterrad ist auch noch frei und auf das Bedürfnis des Einzelnen einfach einzustellen durch verschieden große Kettenblätter. Das ermöglicht nun hohe Geschwindigkeiten und auch problemlos Bergfahrten zu absolvieren ohne das ich zwei spezielle Fahrräder besitze. Dadurch brauche ich auch keine Angst nicht mehr zu haben falls auf einer unbekannten Strecke doch mal ein Berg auftaucht. Auch hält die Kette viel länger als normal weil sie immer gerade verläuft. Bis zu 10 facher Standzeit ist möglich. (Siehe E-Bikes nach ca. 2000 Km muß der gesamte Antriebsstrang gewechselt werden.)Calculate the gear ratio at 11/46 to 46/11, and the final gear ratio on the rear wheel is also flexible and easy to adjust to individual needs thanks to different chainring sizes. This now allows for high speeds and easy uphill rides without having to own two dedicated bikes. This also means I no longer have to worry if a hill appears on an unfamiliar route. The chain also lasts much longer than normal because it always runs straight. It's possible to last up to 10 times longer. (See e-bikes: the entire drivetrain needs to be replaced after approximately 2,000 km.)
Die Kettenblätter werden auch viel gleichmäßiger verschlissen und halten dadurch auch viel länger. Ein Kettenschutz für die Hosen ist dadurch auch nicht mehr erforderlich weil man mit den Beinen nicht mehr zur Kette kommen kann.The chainrings also wear much more evenly and therefore last much longer. A chain guard for your trousers is also no longer necessary, as your legs can no longer reach the chain.
Auch ist es möglich nur vorne oder hinten einen Gang weiter zu Schalten und man hat dadurch immer einen Zwischengang und somit auch das doppelte an Gängen was auf der Kassette an Zahnrädern ist. Auch ist die Kurbellänge einfach zu ändern, indem man nicht die ganze Kurbelgarnitur wechseln muß sondern nur die einzelnen Kurbeln. So kann man auch mal einfach eine andere Kurbellänge versuchen.It's also possible to shift up one gear only at the front or rear, which always gives you an intermediate gear and thus doubles the number of gears on the cassette. The crank length is also easy to change, as you don't have to replace the entire crankset, just the individual cranks. This way, you can simply try a different crank length.
Durch diese Schaltung werden auch natürlich die Gelenke viel mehr geschont weil man immer den richtigen Gang zur Verfügung hat. Auch wenn man mit Gepäck unterwegs ist braucht man nicht extra vorher die Übersetzung zu ändern.This gear system also protects your joints much more, because you always have the right gear available. Even when traveling with luggage, you don't need to change the gear ratio beforehand.
Es können Kassetten von 2 bis 12 Zahnräder standardmäßig verbaut werden.Cassettes with 2 to 12 gears can be installed as standard.
Die Übersetzung auf das Hinterrad kann man der Größe des Hinterrads entsprechend anpassen(12).The gear ratio to the rear wheel can be adjusted according to the size of the rear wheel(12).
