Abstract
Description
Die Erfindung betrifft ein Dreigang-Schaltgetriebe, insbesondere für Kindertretfahrzeuge, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a three-speed manual transmission, in particular for child pedal vehicles, according to the preamble of claim 1.

der
Die Aufgabe der Erfindung besteht somit darin, ein Dreigang-Schaltgetriebe, insbesondere für Kindertretfahrzeuge, anzugeben, bei dem die Kette auf einfache Weise und ohne Beeinflussung der Schaltpositionen der Schaltbetätigung zu spannen ist.The The object of the invention is thus to provide a three-speed manual transmission, especially for children's pedal vehicles, specify where the chain is simple and without interference the switching positions of the switching operation is to be clamped.
Diese Aufgabe wird durch ein Dreigang-Schaltgetriebe, insbesondere für Kindertretfahrzeuge, mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a three-speed manual transmission, especially for child pedal vehicles, solved with the features of claim 1.
Erfindungsgemäß ist die Tretkurbelwelle des Umlaufgetriebes des Dreigang-Schaltgetriebes zur Spannung der Kette vom Umlaufgetriebe zu den Fahrzeugrädern in Befestigungsscheiben exzentrisch gelagert. Weiterhin sind einerseits die Verzahnungen der Befestigungsscheiben und der entsprechenden Arretierelemente des Umlaufgetriebes lösbar und können in einer ersten Richtung gegeneinander verdreht werden. Andererseits sind Haltestifte der Haltescheibe mit einer ungleichen Teilung gegenüber der Verzahnung der Befestigungsscheiben versehen. Es kann durch Verdrehung in einer zweiten Richtung eine derartige Einschnapp Position gewählt werden, dass es möglich ist, eine Kettenspannung so vorzunehmen, dass die Rastpositionen des Gangschalthebels im Fahrzeuggehäuse nahezu unverändert bleiben.According to the invention Pedal crankshaft of the epicyclic gearbox of the three-speed gearbox for tensioning the chain from the planetary gear to the vehicle wheels in Mounting discs eccentrically mounted. Furthermore, on the one hand the toothings of the mounting washers and the corresponding ones Locking elements of the planetary gear detachable and can in a first direction be twisted against each other. On the other hand, retaining pins are the Holding disc with an unequal pitch relative to the teeth of the mounting discs Mistake. It can be twisted in a second direction such snap position be chosen that it is possible to make a chain tension so that the locking positions of Gear shift lever in the vehicle housing almost unchanged stay.
Weitere vorteilhafte Ausbildungen des Dreigang-Schaltgetriebes, insbesondere für Kindertretfahrzeuge, sind in den abhängigen Ansprüchen angegeben.Further advantageous embodiments of the three-speed gearbox, in particular for child pedal vehicles, are in the dependent claims specified.
Im Folgenden wird anhand der Figuren ein Ausführungsbeispiel des erfindungsgemäßen Dreigang-Schaltgetriebes, insbesondere für Kindertretfahrzeuge, näher beschrieben.in the Below is an exemplary embodiment of the three-speed gearbox according to the invention with reference to the figures, especially for Child pedal vehicles, closer described.
