Title (EN) A LUBRICATION SYSTEM FOR A GEARBOX ARRANGED IN A VEHICLE
(FR) SYSTÈME DE LUBRIFICATION POUR BOÎTE DE VITESSES DISPOSÉE DANS UN VÉHICULE
Abstract:
(EN) The present invention relates to a lubrication system (8) for a gearbox (3) which is arranged in a motor vehicle (1). The lubrication system comprises a first lubrication circuit (9) with a mechanical pump (12) delivering lubricant to the gearbox (3) and a second lubrication circuit (20) with an electric pump delivering lubricant to the gearbox (3). The mechanical pump (12) is driven by a component in a powertrain of the vehicle via a mechanical transmission (13). The mechanical transmission (13) comprises a coupling member (15) movably arranged between a connected state in which it transfers a driving force from said component (14) to the mechanical pump (12) and a disconnected state in which it breaks the transfer of driving force from the component (14) to the mechanical pump (12). A control unit (26) is configured to move the coupling member (15) to the disconnected state when the electric pump (21) has capacity to deliver a required lubricant flow to the gearbox (3).
(FR) La présente invention concerne un système de lubrification (8) pour une boîte de vitesses (3) qui est disposée dans un véhicule automobile (1). Le système de lubrification comprend un premier circuit de lubrification (9) comprenant une pompe mécanique (12) délivrant du lubrifiant à la boîte de vitesses (3) et un second circuit de lubrification (20) comprenant une pompe électrique délivrant du lubrifiant à la boîte de vitesses (3). La pompe mécanique (12) est entraînée par un composant dans un groupe motopropulseur du véhicule par l'intermédiaire d'une transmission mécanique (13). La transmission mécanique (13) comprend un élément d'accouplement (15) agencé de façon mobile entre un état connecté dans lequel il transfère une force d'entraînement en provenance dudit composant (14) à la pompe mécanique (12) et un état déconnecté dans lequel il interrompt le transfert de force d'entraînement du composant (14) à la pompe mécanique (12). Une unité de commande (26) est conçue pour déplacer l'élément d'accouplement (15) vers l'état déconnecté lorsque la pompe électrique (21) a la capacité de délivrer un flux de lubrifiant requis à la boîte de vitesses (3).
