Abstract
Zugmitteltrieb, dadurch gekennzeichnet, dass die excentrische Schwenkung des Antriebsrades (2) und die dadurch hervorgerufene Achsabstandsänderung mittels gekoppelter Gelenke (4, 6, 13, 14) durch Schienen (5) oder Räder (15) ausgeglichen wird, derart, dass in beiden Trumms entsprechend der Erfordernisse im gewünschten maße eingeschwenkt wird.traction drive, characterized in that the eccentric pivoting of the drive wheel (2) and the resulting change in axle distance by means of coupled joints (4, 6, 13, 14) by rails (5) or wheels (15) is compensated, so that in both Trumms accordingly the requirements swung in the desired dimensions becomes.
Description
Die vorliegende Erfindung betrifft den Ausgleich der Änderung des Achsabstandes zweier Kettenräder, ohne dass daher eine Phasenverschiebung auftritt.The The present invention relates to the compensation of the change the center distance of two sprockets, without therefore a Phase shift occurs.
Aus
der Patentliteratur (
Die Verlagerung der Kurbelwelle führt zur Änderung des Achsabstandes im Steuertrieb. Da die Verstellung dynamisch ist und je nach Position der Kurbelwelle Zugmittel (Riemen, Kette) freigegeben (spannen) oder benötigt wird (lösen), muss ein Ausgleich integriert werden. Herkömmliche Riemen- oder Kettenspanner sind dafür nicht geeignet. Damit beim Verstellen keine Phasenverschiebeng zwischen Kurbelwelle und Nockenwelle auftaucht, ist der Ausgleich möglichst symmetrisch zu realisieren.The Displacement of the crankshaft leads to change the center distance in the control drive. Because the adjustment is dynamic and depending on the position of the crankshaft traction means (belt, chain) released (cocking) or needed (solving), must be a compensation to get integrated. Conventional belt or chain tensioners are not suitable for it. So when adjusting no Phase shifting between crankshaft and camshaft emerges, the balance should be realized as symmetrically as possible.
Der Erfindung liegt nun die Aufgabe zu Grunde, diese Nachteile aus der Welt zu schaffen.Of the Invention is now the object of these disadvantages from the To create the world.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, indem eine Nebenlagerstelle erzeugt wird und diese fest mit dem Block verbunden ist. Von hier aus kann der Steuertrieb wie gewohnt fortgesetzt werden. Zwischen dem Kurbelwellenrad und dem Zwischenrad ändert sich beim Schwenken der Excentereinheit der Achsabstand. Je nach Anordnung kann dieses wenige Zehntel Millimeter bis mehrere Millimeter betragen. Um beim Verstellen die Zugmittelspannung zu halten, muss ein mit dem Schwenksystem (Excentereinheit) gekoppelter Mechanismus Spannsysteme nachführen. Dieses wird mit einseitig angelenkten Spannschienen bewerkstelligt, so dass synchron eine Anpassung der Schienenlage gewährleistet wird.These Problem is solved according to the invention characterized by creating a sub-depository and this firmly with the Block is connected. From here, the tax drive as usual to be continued. Between the crankshaft gear and the idler wheel changes when pivoting the Excentereinheit the center distance. Depending on Arrangement can this few tenths of a millimeter to several millimeters be. In order to hold the Zugmittelspannung when adjusting, must a mechanism coupled to the pivoting system (eccentric unit) clamping systems tracking the. This is with one-sided hinged slide rails brought about so that synchronous adjustment of the rail position is guaranteed.
Eine weitere Art und Weise ist die Realisierung des Ausgleiches mit Rädern. Dabei werden zwei Räder an ein Gestänge gelagert und um einen Drehpunkt verdreht. Diese Verdrehung ist mit der Verdrehung des Excenters gekoppelt, so dass mit der passenden Auslegung der Gelenklängen, die gewünschte Nachführung des Zugmittels bewerkstelligt wird.A Another way is the realization of compensation with wheels. Two wheels are mounted on a linkage and twisted around a pivot. This twist is with the twist Coupled with the Excenters, so with the appropriate interpretation of the Joint sounds, the desired tracking the traction means is accomplished.
Dieser Art des Zugmitteltriebes kann auch getriebeseitig zur Anwendung kommen.This Type of traction drive can also be used on the transmission side come.
