(EN) TENSIONER UNIT FOR ENGINE ACCESSORY BELT
(FR) ENSEMBLE TENDEUR POUR COURROIE DE MACHINE AUXILIAIRE
要約
(EN) A tensioner unit (A) for an engine accessory belt is provided which includes a pivot arm (2) supported to be pivotable about a fulcrum shaft (4); a tension pulley (3) supported by the pivot arm (2); spring abutment pins (34) and a damper abutment pin (41) that are fixed in position; compression coil springs (30) pressing the respective spring abutment pins (34) so as to bias the pivot arm (2) due to the reaction forces received from the spring abutment pins (34); and a hydraulic damper (31) mounted in the pivot arm (2) so as to be in contact with the damper abutment pin (41).
(FR) La présente invention concerne une unité de tendeur pour une courroie de machine auxiliaire qui est configurée pour être pourvue: d'un bras oscillant (2) qui est supporté de façon à pouvoir osciller sur un arbre de pivot (4); d'une poulie de tension (3) supportée par le bras oscillant (2); d'une broche de butée de ressort (34) et d'une broche de butée d'amortisseur (41) qui sont disposées et fixées; d'un ressort hélicoïdal de compression (30) qui appuie sur la broche de butée de ressort (34) de façon à solliciter le bras oscillant (2) avec la force de réaction reçue à partir de la broche de butée de ressort (34); et d'un amortisseur hydraulique (31) qui est fixé au bras oscillant (2) de façon à être en contact avec la broche de butée d'amortisseur (41).
