Abstract

L'invention concerne un dispositif de transmission de puissance pour un véhicule, le dispositif comportant une paroi latérale (17a) vers l'avant d'une partie d'engrènement (38) entre un engrenage mené final (29) et un engrenage d'entraînement final (28), ladite paroi étant munie d'un évidement de collecte d'huile (50) servant à collecter l'huile ayant été ramassée par l'engrenage mené final (29) à partir d'une partie inférieure d'un carter d'engrenage (16, 17), et à alimenter en huile un palier (32). Par conséquent, même lorsque l'huile ramassée par l'engrenage mené final (29) est bloquée par la partie d'engrènement (38) et a peu de chances d'atteindre le palier (32), l'huile ayant traversé la partie d'engrènement (38) peut être collectée de manière efficace par l'évidement de collecte d'huile (50) et alimentée au palier (32), ce qui permet de lubrifier efficacement le palier (32) portant un engrenage différentiel (13).
