Abstract

La présente invention concerne un vilebrequin. Il s'agit d'un vilebrequin moulé doté d'évidements traversant les flasques-manivelles et réalisés dans le matériau de coulée formant les tourillons et manetons attenant à ces flasques par mise en place de noyaux avant la coulée, évidements servant à limiter le poids des masses rotatives asymétriques et des éléments d'équilibrage de celles-ci, caractérisé par le fait que le rapport entre la distance minimale a séparant le congé du maneton de la génératrice de l'évidement 9 d'une part et le diamètre 18 du maneton 4 d'autre part se situe entre 0,45 et 0,46, en particulier à la valeur 1/2, et que la distance a est à peu près de l'ordre de celle W séparant l'un de l'autre les congés voisins (20 et 27) du maneton 4 et du tourillon 5, 6. Ce vilebrequin peut être utilisé dans les moteurs.
