Title
(DE) SPANNVORRICHTUNG FÜR EINEN STEUERTRIEB
(EN) TENSIONING DEVICE FOR A CONTROL DRIVE
(FR) DISPOSITIF TENDEUR POUR ORGANE DE COMMANDE
Abstract
(DE)
Eine Spannvorrichtung für die Kette (3) eines Verbrennungsmotors, beispielweise eines Steuertriebes, weist eine Führungsschiene (8), einen schwenkbar gelagerten Spannhebel (15) und ein Spannelement (13) auf, welches mittels einer Druckfeder (14) eine Spannkraft auf den Gleitschuh (18) ausübt. Erfindungsgemäß sind an dem, eine feste Schwenkachse (16) aufweisenden Spannhebel (15) zwei in unterschiedlichen Richtungen auf die Kette (3) einwirkende Gleitschuhe (17, 18) angeordnet. Dadurch wird die Spannvorrichtung in einem sehr kleinen Einbauraum einsetzbar und kann eine große Kettenlängung ausgleichen.
(EN)
The invention concerns a tensioning device for the chain (3) of an internal combustion engine, for example a control drive, the tensioning device comprising a guide rail (8), a pivotably mounted tension lever (15) and a tension element (13) which exerts tension force on the sliding block (18) by means of a pressure spring (14). According to the invention, two sliding blocks (17, 18) acting on the chain (3) in different directions are disposed on the tension lever (15) which has a fixed pivot axis (16). In this way, the tensioning device can be used in a very small space and can equalize a long chain elongation.
(FR)
La présente invention concerne un dispositif tendeur pour la chaîne (3) d'un moteur à combustion interne, par exemple d'un organe de commande, comportant une glissière (8), un levier de tension (15) monté pivotant et un élément de tension (13), ce dernier exerçant au moyen d'un ressort de compression (14) une force de tension sur le patin (18). Selon la présente invention, deux patins (17, 18) sont disposés sur le levier de tension (15) comportant un axe de pivotement fixe (16). Ces patins agissent sur la chaîne (3) dans deux directions différentes, ce qui permet d'utiliser le dispositif de tension dans un espace de montage limité et de compenser un allongement de chaîne important.
