Abstract

Système de lubrification de roulement (6) d'une sortie de différentiel tournant dans un carter (1, 7), par guidage de l'huile raclée autour du boîtier de différentiel sur une partie conique du carter en direction du roulement (6), caractérisé en ce que l'huile est acheminée en direction du roulement par un canal brut de fonderie (4) dans la paroi intérieure du carter, qui débouche à mi-hauteur du roulement.Bearing lubrication system (6) of a differential output rotating in a housing (1, 7), by guiding the scraped oil around the differential housing on a conical portion of the housing towards the bearing (6), characterized in that the oil is conveyed in the direction of the rolling by a raw casting channel (4) in the inner wall of the housing, which opens at half height of the bearing.
