Abstract

La présente invention a pour objet un système (100) de lubrification d’un vilebrequin (10) comportant un tourillon (12) dans lequel est percé un conduit diamétral (48) dont les deux extrémités opposées (50, 52) débouchent dans la surface périphérique (13) du tourillon (12), comportant une première bague (30) de coussinet qui comporte au moins un tronçon (42-1, 42-2) de rainure circulaire et un perçage radial associé (46-1, 46-2) qui est connecté à un circuit d'amenée d'huile, caractérisé en ce que la surface périphérique convexe (13) du tourillon (12) comporte au moins un tronçon (54 1, 54 2) de gorge circulaire qui communique avec une extrémité (50, 52) du conduit diamétral (48) du tourillon (12) et qui s’étend selon un secteur angulaire déterminé de manière que, pour au moins certaines positions angulaires du tourillon (12) par rapport au palier, le tronçon de rainure circulaire (42-1, 42-2) de la première bague (30) communique avec le tronçon (54-1, 54-2) de gorge circulaire du tourillon (12).
