Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft eine Kettenspannvorrichtung eines Verbrennungsmotors, mit einer Kettengleitschiene, die für die Einwirkung auf eine Antriebskette vorgesehen ist, wobei sie für die verschwenkbare Anordnung an dem Verbrennungsmotor eine Schwenkachse aufweist und einem Spannelement zugeordnet ist, in welchem sich eine die Verschwenkung der Kettengleitschiene bewirkende Drehfeder befindet.The Invention relates to a chain tensioning device of an internal combustion engine, with a chain slide, designed for action on a drive chain is provided, while for the pivotable assembly on the internal combustion engine has a pivot axis has and is associated with a clamping element in which a pivoting the chain slide causing torsion spring located.
Hintergrund der Erfindungbackground the invention
Kettentriebe von Verbrennungsmotoren mit Kunststoffgleitschuhen und Kettenspanner mit hydraulischer Dämpfung sind bekannt. Nachteile der hydraulischen Spanner bestehen in der zweiteiligen Ausführung, welche sowohl eine Kettengleitschiene als auch ein zusätzliches Spannelement als einzelne Bauteile erfordert. Dadurch ergeben sich hohe Herstellungskosten, ein großes Ge wicht und wegen der Befestigung des Spannelementes am Motor und der erforderlichen Ölversorgung eine aufwändige Bearbeitung.chain drives combustion engines with plastic skates and chain tensioners with hydraulic damping are known. Disadvantages of the hydraulic tensioner exist in the two-piece design, which both a chain slide and an additional Clamping element required as individual components. This results high production costs, a large Ge weight and because of the attachment the tensioning element on the engine and the required oil supply an elaborate one Processing.

Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, eine am Motor leicht montierbare Kettenspannvorrichtung zu schaffen, welche ein geringes Gewicht aufweist und mit mechanischer Reibung arbeitet, also kein Hydrauliköl benötigt. Die Vorrichtung soll, wegen des begrenzten Ausgleichsweges im Vergleich zu einem hydraulischen Spanner mit einem Ratschenmechanismus, auch in kurzen Kettentrieben eingesetzt werden können.Of the Invention is based on the object, one easily mounted on the engine To provide a chain tensioning device which has a low weight and works with mechanical friction, so no hydraulic oil needed. The Device should, because of the limited compensation path in comparison to a hydraulic tensioner with a ratchet mechanism, too can be used in short chain drives.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Spannelement in der Kettengleitschiene integriert ist und mit dieser eine einstückige Baueinheit bildet. Die so ausgebildete Kettenspannvorrichtung lässt sich in einfacher Weise am Verbrennungsmotor montieren.These Task is inventively characterized solved, that the tensioning element is integrated in the chain slide rail and with this one-piece Building unit forms. The thus formed chain tensioning device can be easily mount to the combustion engine.
Das Spannelement kann von einem mit der Kettengleitschiene einstückig ausgeführten Spannergehäuse, einer darin geradlinig verschiebbar gelagerten Flachbuchse, einer in dieser drehbar gelagerten Exzenterbuchse, einem darin exzentrisch angeordneten Innenbolzen, an welchem die Exzenterbuchse drehbar gelagert ist, und einer Befestigungsschraube gebildet sein, welche an dem Innenbolzen in eine exzentrische zweite Befestigungsbohrung eingesteckt und für das Anschrauben des Spannelementes an dem Verbrennungsmotor vorgesehen ist. Dabei können die Kettengleitschiene mit dem Spannergehäuse und/oder die Flachbuchse und/oder die Exzenterbuchse aus Kunststoff hergestellt sein. Dadurch ergibt sich in vorteilhafter Weise für die Kettenspannvorrichtung ein geringes Gewicht.The Clamping element can of a one piece with the chain slide rail tensioner housing, a Sliding bush mounted linearly in it, one in this rotatably mounted eccentric bush, an eccentric arranged therein Inner bolt, on which the eccentric bush is rotatably mounted, and a fastening screw, which on the inner bolt in an eccentric second mounting hole inserted and for screwing the tensioning element is provided on the internal combustion engine. there can the chain slide with the tensioner housing and / or the flat bush and / or the eccentric bush made of plastic. Thereby results in an advantageous manner for the chain tensioning device a low weight.
