Abstract

Elément absorbant les vibrations (6a, 6b) situé à l'intérieur d'un évidement annulaire (5, 7) sur le côté de l'ensemble constitué par la bielle (1) et par le chapeau (4) ou, de plus, dans un autre mode de réalisation, entre le palier principal de vilebrequin et les coussinets principaux du vilebrequin. Cet élément absorbant les vibrations est composé, de préférence, de deux pièces (6a, 6b) conçues pour loger dans une partie évidée (5) de la bielle (1) et dans une partie évidée (7) du chapeau (4) afin de faciliter son montage. Cet élément (6a, 6b) absorbe les vibrations entre l'ensemble constitué par la bielle (1) et par le chapeau (4) et le vilebrequin. De même, cet élément (6a, 6b) absorbe les vibrations entre le vilebrequin et le bloc moteur quand il est placé entre le vilebrequin et le palier principal du vilebrequin. Dans des moteurs classiques comportant un ou de multiples cylindres en ligne, cet élément est placé des deux côtés de l'ensemble constitué par la bielle et par le chapeau. Dans des moteurs en V comportant deux bielles contiguës, une de ces bielles possède un élément unique absorbant les vibrations situé sur le côté de contact avec le vilebrequin.
