Abstract
Description
Diese
Fahrradschaltung besteht grundsätzlich
aus zwei Untergruppen und zwar aus dem Verstell-Mechanismus und der Verstell-Ableitung.
Beschreibung des Verstell-Mechanismus:Description of the adjustment mechanism:
Der
Verstell-Mechanismus besteht aus einer Mitnehmerscheibe(
Der Bereich der stufenlosen Verstellung entspricht einem Bereich von 40 zu 64 Zähnen, was ca. einer 3-stufigen Kettenradschaltung an der Pedalachse entspricht.Of the Range of stepless adjustment corresponds to a range of 40 to 64 teeth, what about a 3-stage sprocket on the pedal axle corresponds.
Bei
der Verstellung der Kettenräder(
EA-bedeutet im Eingriff bei Verstellung nach außen.EA means in the case of adjustment to the outside.
AA-bedeutet in Anpassung bei Verstellung nach außen.AA means in adaptation for adjustment to the outside.
Bei
der Verstellung der Kettenräder(
EI -bedeutet im Eingriff bei Verstellung nach innen. AI -bedeutet in Anpassung bei Verstellung nach innen.EGG - means engaged in adjustment to the inside. AI means in Adjustment when adjusting inwards.
Bei
konstanter Übersetzung
sind alle Kettenräder(
Die
stufenlose Verstellung ist nicht nur auf die Kettenteilung einstellbar,
sonder auch auf Brüche der
Kettenteilung (zum Beispiel 42,6 Zähne), weil sich die Kettenräder(
Das hat zur Folge, das man dadurch in wahrsten Sinne des Wortes eine stufenlose Schaltung erreicht.The As a result, it literally becomes one infinitely variable switching achieved.
Die
Abwicklung der Kette läuft über einem Polygon
den die Kettenräder(
Wirkungsgrad dieser stufenlosen Schaltung entspricht dem Wirkungsgrad eines Kettentriebes, weil sich die Zahnräder der Verstellableitung bei konstanter Übersetzung nicht drehen.efficiency this stepless circuit corresponds to the efficiency of a chain drive, because the gears do not turn the adjustment lead with constant translation.
Ein
Vorteil dieser Erfindung ist auch, das sich die Kette (
Weiterer Vorteil ist, das man bei Belastung sowie beim Rückwertstreten auch verstellen kann. Selbstverständlich ist eine Schaltung (Verstellung) ohne Belastung günstiger.Another The advantage is that you also adjust the load and the Rückwertstreten can. Of course is a circuit (adjustment) cheaper without load.
Diese stufenlose Fahrradschaltung bildet mit den bekannten gestuften Schaltungen am Hinterrad (Ketten oder Nabenschaltungen) eine ideale Lösung als komplette stufenlose Schaltung in den bekannten Schaltbereich der jetzigen Stufenschaltungen. Mit einer zusätzlichen Zahnradübersetzung in der Hinternabe ist diese stufenlose Schaltung auch an der Hinterachse anwendbar.These Stepless bicycle circuit forms with the known stepped circuits at the rear wheel (chains or hub gears) an ideal solution as complete stepless circuit in the known switching range of current stage circuits. With an additional gear ratio in the rear hub, this stepless circuit is also on the rear axle applicable.
Diese Erfindung eignet sich im Allgemeinem auch für alle gängigen Zugmittel wie Kette, Zahnriemen, Keilriemen, Flachriemen u.s.w. und ist auch Fahrzeugbau anwendbar.These Invention is generally suitable for all common traction means such as chain, Timing belt, V-belt, flat belt and so on and is also vehicle construction applicable.
