Abstract
Description
In der Praxis sind viele nur in einer Drehrichtung wirkende Freilaufsysteme für Vielzahl von Anwendungsfällen bekannt, jedoch nur sehr wenige Freilaufsysteme, die sowohl im und gegen den Uhrzeigersinn wirken können.In practice, many are only in one Freewheel systems acting in the direction of rotation are known for a large number of applications, however, very few freewheel systems, both in and against can work clockwise.
Diese doppeltwirkenden Freiläufe benötigen zum Sperren des Freilaufes ein relativ hohes, von außerhalb des Freilaufsystems eingeleitetes Rückhaltereib- momentThese double-acting freewheels need to Locking the freewheel a relatively high one, from outside the freewheel system initiated retainer moment
Die im Patentanspruch 1,2 und 3 angegebene Erfindung benötigt kein von außerhalb des Freilaufes eingeleitetes Rückhaltemoment.The specified in claim 1,2 and 3 Invention needed no from outside retention torque initiated by the freewheel.
Die Wirkungsweise ergibt sich wie
im Patentanspruch 1,2,3 und 4 schon beschrieben:
In einer Buchse
einer Welle ist mit einem umlaufenden Spalt ein Sperr-Ring positioniert,
der beim Einsetzen der Drehbewegung einer zweiten Welle automatisch
eine reib- oder formschlüssige
Verbindung zwischen den beiden Wellen herstellt.The mode of operation results as already described in patent claims 1, 2, 3 and 4:
A locking ring is positioned in a bushing of a shaft with a circumferential gap, which automatically establishes a frictional or positive connection between the two shafts when the rotational movement of a second shaft begins.
Die exzentrische Verstellung des Sperr-Ringes erfolgt über ein Stellelement z.B. einer Nocke auf der zweiten Welle innerhalb des Sperr-Ringes.The eccentric adjustment of the Locking ring is made via an actuator e.g. a cam on the second shaft inside the lock ring.
Der in jeder Nockenstellung anfangs durch elastische Distanzhalter oder sonstige Rückhalteeinrichtungen in Position gehaltene Sperr-Ring wird dabei zunächst entweder über eine durch die Massenträgheit oder Schwerkraft am Rotieren gehinderten Bremsscheibe an einem wikungslosen Mitdrehen mit der Nocke durch geringfügige Reib- oder Magnetkräfte gehindert, so dass er sich exzentrisch in den Spalt hinein versetzt oder durch eine Bremsscheibe, die durch eine Befestigung außerhalb des Freilaufes an einer Drehbewegung gehindert istThe one in every cam position initially by elastic spacers or other restraint devices in position held lock ring is initially either via a through inertia or gravity to prevent the rotating disc from rotating Co-rotation with the cam prevented by slight friction or magnetic forces, so that it moves eccentrically into or through the gap a brake disc, which is attached to an outside of the freewheel Is prevented from rotating
Der Doppel-Freilauf eignet sich unter anderen dazu, Kindertretfahrzeuge bei stillstehender Tretkurbel zu schieben oder eine ungewollt hohe Fahrgeschwindigkeit über die Tretkurbel zu reduzieren.The double freewheel is suitable under others, children's pedal vehicles with the pedal crank at a standstill to push or an unintentionally high driving speed over the Reduce pedal crank.
