Title (EN) AN OIL DISTRIBUTOR FOR A LUBRICATING AND COOLING SYSTEM IN A POWERTRAIN
(FR) DISTRIBUTEUR D'HUILE POUR UN SYSTÈME DE LUBRIFICATION ET DE REFROIDISSEMENT DANS UN GROUPE MOTOPROPULSEUR
Abstract:
(EN) The invention relates to an oil distributor (2) for a lubricating and cooling system (60) in a powertrain (14), the oil distributor (2) comprising a housing (20) provided with at least one first oil inlet (22) and at least two oil outlets (26, 28), wherein a first oil outlet (26) is connected to a first oil chamber (30) and wherein a second oil outlet (28) is connected to a second oil chamber (32); and a piston (34) arranged in a cavity (36) of the housing (20), which piston (34) is movable between a first and a second posi- tion, wherein the first oil outlet (26) is adapted to be connected to a first oil circuit (62) and the second oil outlet (28) is adapted to be connected to a second oil circuit (64). The piston (34) comprises a first bore (38) directed in a longitudinal direction of the piston (34), wherein the second oil chamber (32) is at least in part constituted by the first bore (38) in the piston (34), and wherein the piston (34) comprises a second bore (40) connecting the first bore (38) with an outer periphery of the piston (34), so that when the piston (34) is in the first position the at least one first oil inlet (22) is connected to the first oil chamber (30) and the first oil outlet (26), and when the pis- ton (34) is in the second position the at least one first oil inlet (22) is connected to the second oil chamber (32) and the second oil outlet (28). The invention also relates to a lubricating and cooling system (60) in a powertrain (14), a method of controlling a lubricating and cooling system (60) in a powertrain (14), a powertrain (14), a vehicle (1), a computer program and a computer program product.
(FR) L'invention concerne un distributeur d'huile (2) pour un système de lubrification et de refroidissement (60) dans un groupe motopropulseur (14), le distributeur d'huile (2) comprenant un boîtier (20) pourvu d'au moins une première entrée d'huile (22) et au moins deux sorties d'huile (26, 28), une première sortie d'huile (26) étant reliée à une première chambre d'huile (30) et une seconde sortie d'huile (28) étant reliée à une seconde chambre d'huile (32); et un piston (34) disposé dans une cavité (36) du boîtier (20), lequel piston (34) est mobile entre une première et une seconde position, la première sortie d'huile (26) est conçue pour être connectée à un premier circuit d'huile (62) et la seconde sortie d'huile (28) est conçue pour être connectée à un second circuit d'huile (64). Le piston (34) comprend un premier alésage (38) dirigé dans une direction longitudinale du piston (34), la seconde chambre d'huile (32) étant au moins en partie constituée par le premier alésage (38) dans le piston (34), et le piston (34) comprenant un second alésage (40) reliant le premier alésage (38) à une périphérie externe du piston (34), de telle sorte que, lorsque le piston (34) est dans la première position, l'au moins une première entrée d'huile (22) est reliée à la première chambre d'huile (30) et à la première sortie d'huile (26), et lorsque le piston (34) est dans la seconde position, l'au moins une première entrée d'huile (22) est reliée à la seconde chambre d'huile (32) et à la seconde sortie d'huile (28). L'invention concerne également un système de lubrification et de refroidissement (60) dans un groupe motopropulseur (14), un procédé de commande d'un système de lubrification et de refroidissement (60) dans un groupe motopropulseur (14), un groupe motopropulseur (14), un véhicule (1), un programme informatique et un produit programme d'ordinateur.
