A tensioner (10, 70, 110) for tensioning a belt includes a support housing (12, 84, 130) at least in part defining a spring cavity (16). A damping member (24, 72, 112) having a first friction bearing surface (56; 96, 98; 164, 166) is at least partially disposed in the spring cavity (16). An arm (14) pivotal y attached to the support housing (12, 84, 130) has a second friction bearing surface (58, 114). A spring (18, 118) is located in the spring cavity (16) and operatively connected to the arm (14) and damping member (24, 72, 112) to pivot the damping member about a pivot location such that the first friction bearing surface (56; 96, 98; 164, 166) of the damping member (24, 72, 112) is biased against the second friction bearing surface (58, 114) of the arm (14) to dampen relative movement between the arm and the support housing (12, 84, 130).
Le tendeur (10, 70, 110) selon la présente invention destiné à tendre une courroie comprend un logement de support (12, 84, 130) définissant au moins en partie une cavité (16) destinée à un ressort. Un élément d'amortissement (24, 72, 112) comportant une première surface de frottement (56; 96, 98; 164, 166) est au moins partiellement disposé dans la cavité (16) destinée au ressort. Un bras (14) attaché pivotant au logement de support (12, 84, 130) possède une seconde surface de frottement (58, 114). Un ressort (18, 118) est placé dans la cavité (16) destinée au ressort et est relié fonctionnellement au bras (14) et à l'élément d'amortissement (24, 72, 112) de façon à faire pivoter l'élément d'amortissement autour d'un pivot de sorte que la première surface de frottement (56; 96, 98; 164, 166) de l'élément d'amortissement (24, 72, 112) soit soumise à une contrainte le faisant reposer contre la seconde surface de frottement (58, 114) du bras (14) pour amortir le mouvement relatif entre le bras et le logement de support (12, 84, 130).
