Description
Stufenlos verstellbares Breitkeilriemengetriebe Die Erfindung betrifft ein stufenlos verstellbares Breitkeilriemengetriebe mit spannkraftabhängigem Längenausgleich, insbesondere für Iandmaschinen .Infinitely variable wide V-belt transmission The invention relates to an infinitely adjustable wide V-belt drive with length compensation depending on the tension force, especially for agricultural machinery.
bekannt sind stufenlos verstellbare Breitkeilriemengetriebe, 8ogenannte Keilriemenvariatoren, deren Achsabstand konstant ist.Infinitely variable wide V-belt transmissions are known, the so-called V-belt variators whose center distance is constant.
Die dabei verwendeten Breitkeilriemen längen eich und achränken den Regelbereich des Keilriemenvariators mit zunehmender Nutzungsdauer ein.The wide V-belts used for this are both long and short Control range of the V-belt variator with increasing service life.
Der Nachteil derartiger Ausführungen liegt folglich in der begienzten Einsatzdauer sowie in dem nach längerer Nutzungsdauer eingeschränkten Regelbereich.The disadvantage of such designs is consequently that they are limited Duration of use as well as in the control range restricted after a longer period of use.
Zweck der Erfindung ist es, die Begrenzung der Einsatzdauer und des Regelbereiches von Keilriemenvariatoren zu beseitigen.The purpose of the invention is to limit the duration of use and the To eliminate the control range of V-belt variators.
Der Erfindung liegt die Aufgabe zugrunde, ein stufenlos verstellbares Breitkeilriemengetriebe zu schaffen, das durch die Verstellemöglichkeit des Achsabstandes eine unbegrenzte Einsatzdauer bei vollem Regelbereich gewährleistet.The invention is based on the object of a continuously adjustable To create wide V-belt drive through the ability to adjust the center distance guarantees an unlimited period of use with the full control range.
Erfindungsgemäß wird das erreicht, indem die Abtriebsscheiben eines bekannten Breitkeilriemengetriebes auf einer Schwinge angeordnet sind, die am Rahmen des Breitkeilriemengetriebes gelagert ist und deren freien Schenkel ein verstellbares spannkraftbegrenzendes Spannelement aufweist, welches mit dem Rahmen in Verbindung steht.According to the invention this is achieved by the output disks of a known wide V-belt transmission are arranged on a rocker arm on the frame of the wide V-belt drive is mounted and its free leg is adjustable Has clamping force limiting clamping element, which is connected to the frame stands.
Die Längung des Keilriemens wird durch die Veränderung des Achsabstandes zwischen Antriebs- und Abtriebsscheibe somit ausgegleichen und der volle Regelbereich des Breitkeilriemengetriebes dadurch wieder hergestellt.The elongation of the V-belt is achieved by changing the center distance balance between drive and driven pulley and the full control range of the wide V-belt transmission is thereby restored.
Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden, In der Zeichnung zeigen: Fig. 1: eine Ansicht des Keilriemenvariators mit verstellbarer Schwinge, Fig. 2: die Seitenansicht zu Fig. 1, Das Breitkeilriemengetriebe besteht aus einer hydraulisch verstellbaren Antriebsscheibe 1 und einer mittels Federkraft zwangaldufig verstellbaren Abtriebsscheibe 2.The invention is to be described in more detail below using an exemplary embodiment be explained The drawing shows: FIG. 1: a view of the V-belt variator with adjustable rocker, Fig. 2: the side view to Fig. 1, The wide V-belt transmission consists of a hydraulically adjustable Drive pulley 1 and an output pulley which can be forced to adjust by means of spring force 2.
Die Abtriebsscheibe 2 ist erfindungsgemäß auf einer Schwinge 3 gelagert. Die Schwinge 3 ist im Drehpunkt 4 am Rahmen 5 des Breitkeilriemengetriebes schwenkbar angeordnet.According to the invention, the output disk 2 is mounted on a rocker arm 3. The rocker 3 can be pivoted at the pivot point 4 on the frame 5 of the wide V-belt transmission arranged.
Am gegentlberlie'genden Ende der an aer Schwinge 3 gelagerten Abtriebsscheibe 2 ist ein spannkraftbegrenzendes Spannelement 6 angeordnet, das mit dem Rahmen 5 in Verbindung steht.At the opposite end of the driven pulley mounted on the rocker arm 3 2, a clamping force-limiting clamping element 6 is arranged, which is connected to the frame 5 communicates.
Tritt bei längerer Nutzungsdauer eine Längung des Keilriemens 7 und somit eine Einschränkun& des Regelbereiches ein, so wird mit Hilfe des spannkraftbegrenzendes Spannelement 6 die Längung des Keilriemens 7 durch Veränderung des Achsabstandes zwischen der Antriebsscheibe 2 und der Abtriebsscheibe 3 ausgeglichen und damit der Regelbereich des Keilriemenvariators wieder hergestellt.If the V-belt 7 and thus a restriction of the control range, with the help of the clamping force limiting Tensioning element 6 the elongation of the V-belt 7 by changing the center distance balanced between the drive pulley 2 and the driven pulley 3 and thus the control range of the V-belt variator is restored.
