Abstract

Réducteur pour véhicule automobile, comprenant un arbre creux (2) supportant au moins un engrenage (3) et des roulements compris dans un carter (1) et définissant un espace intérieur (5c) et un collecteur amont (5a). Le réducteur comprend une mise à l’air libre (6) connectant le collecteur amont (5a) et l’environnement du réducteur, le réducteur comprenant par ailleurs un déflecteur (7) disposé dans le collecteur amont (5a), conçu de sorte à rediriger l’huile dans le collecteur amont (5a) vers le roulement conique amont (4a) de sorte qu’elle soit aspirée vers l’espace intérieur (5c), le déflecteur (7) ménageant par ailleurs la mise à l’air libre du collecteur amont avec l’environnement. Figure pour l’abrégé : Fig 3Reducer for a motor vehicle, comprising a hollow shaft (2) supporting at least one gear (3) and bearings included in a casing (1) and defining an interior space (5c) and an upstream collector (5a). The reducer comprises a vent (6) connecting the upstream collector (5a) and the environment of the reducer, the reducer further comprising a deflector (7) arranged in the upstream collector (5a), designed so as to redirect the oil in the upstream manifold (5a) towards the upstream tapered bearing (4a) so that it is sucked towards the interior space (5c), the deflector (7) also providing the vent of the upstream collector with the environment. Figure for abstract: Fig 3
