Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen Kettenspanner mit einem Grundkörper, an dem eine auf einen Lagerarm in axialer Richtung aufsteckbare Spannschiene zur Spannung eines Kettentriebs einer Brennkraftmaschine angebracht ist, wobei die Spannschiene über ein Sicherungselement lösbar an einem mit dem Grundkörper verbundenen Formelement befestigbar ist.The invention relates to a chain tensioner with a base body to which a clampable on a bearing arm in the axial direction clamping rail for tensioning a chain drive of an internal combustion engine is mounted, wherein the clamping rail via a fuse element releasably attached to a connected to the main body mold element can be fastened.
Hintergrund der ErfindungBackground of the invention

Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen konstruktiv einfacher aufgebauten Kettenspanner anzubieten, der funktionssicher mit dem Grundkörper verbunden ist.The invention has for its object to offer a structurally simple chain tensioner, which is connected functionally reliable with the body.
Zusammenfassung der ErfindungSummary of the invention
Diese und weitere Aufgaben, die sich u. a. auch aus der nachfolgenden Beschreibung der Erfindung ergeben, werden dadurch gelöst, daß das Formelement zur Lagefixierung der Spannschiene an einer Seitenflanke der Spannschiene anliegt.These and other tasks that u. a. also be apparent from the following description of the invention are achieved in that the mold element for fixing the position of the clamping rail rests against a side edge of the clamping rail.
Damit kann die Spannschiene montagefreundlich durch einfache formschlüssige Verbindung mit dem Lagerarm des Grundkörpers an letzterem angebracht werden und befindet sich in der Transportstellung im angelegten Zustand am Grundkörper in einer durch das Formelement gegen axiales Abrutschen vom Lagerarm gesicherten Stellung. Wenn der erfindungsgemäße Kettenspanner im Kettentrieb angeordnet und die Spannschiene gegen die Kette angefedert ist, die Spannschiene also in Arbeitsstellung ist, verhindert dieses Formelement ebenfalls ein axiales Abrutschen der Spannschiene vom Grundkörper.Thus, the clamping rail mounting friendly by simple positive connection with the bearing arm of the body are attached to the latter and is located in the transport position in the applied state on the body in a secured by the mold member against axial slipping from the bearing arm position. If the chain tensioner according to the invention arranged in the chain drive and the tensioning rail is spring-loaded against the chain, ie the tensioning rail is in working position, this form element also prevents axial slipping of the tensioning rail from the base body.
Die Spannschiene besitzt ein geschlossenes Lagerauge zur allein formschlüssigen Aufnahme des Zapfens des Lagerarms. Eine Anbringung von Einführschlitzen und eine Rastverbindung der Spannschiene mit dem Grundkörper ist nicht erforderlich.The clamping rail has a closed bearing eye for solely positive reception of the pin of the bearing arm. An attachment of insertion slots and a locking connection of the clamping rail with the body is not required.
Ein wesentlicher Grundgedanke des erfindungsgemäßen Kettenspanners liegt darin, daß das zur Aufnahme des Sicherungelementes verwendete Formelement am Grundkörper auch zur Lagefixierung der Spannschiene dient.An essential basic idea of the chain tensioner according to the invention is that the mold element used for receiving the securing element on the base body also serves for fixing the position of the tensioning rail.
Weiter Einzelheiten und Vorteile der Erfindung ergeben sich aus den in den Zeichnungsfiguren beschriebenen Ausführungsbeispielen.Further details and advantages of the invention will become apparent from the embodiments described in the drawing figures.
