Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION PROVIDED WITH A SET OF HYDRAULIC PUMPS
(FR) BOITE DE VITESSES A VARIATION CONTINUE EQUIPEE D'UN ENSEMBLE DE POMPES HYDRAULIQUES
Abstract:
(EN) Continuously variable transmission (1) for transmitting a driving force of an engine (E) to a load (L) to be driven, provided with a set of hydraulic pumps (PM, PE) for realising a pressurised supply of hydraulic medium, at least for the actuation of the transmission (1) within a range of transmission ratios and of at least one auxiliary hydraulic user (U1, U2) of the transmission (1), such as a coupling means (C), which set of hydraulic pumps (PM, PE) comprises a mechanically driven pump (PM), which is driveable by the said engine (E) and is capable of supplying hydraulic medium from a reservoir (10) for hydraulic medium to a main hydraulic line (11) of the transmission (1), and an electrically driven pump (PE), which is driveable by an electric motor independently from the said engine (E) and is arranged in series with the mechanically driven pump (PM), capable of drawing hydraulic medium from the main hydraulic line (11).
(FR) Boîte de vitesses à variation continue (1) pour transmettre la force motrice d'un moteur (E) à une charge (L) à entraîner, équipée d'un ensemble de pompes hydrauliques (PM, PE) de façon à réaliser une alimentation sous pression d'un milieu hydraulique, au moins pour l'actionnement de la boîte de vitesses (1) dans une plage de rapports de boîte et d'au moins un utilisateur hydraulique auxiliaire (U1, U2) de la boîte de vitesse (1) tel qu'un organe de couplage (C), lequel ensemble de pompes hydrauliques (PM, PE) comprend une pompe mécaniquement entraînée (PM), qui peut être mue par ledit moteur (E) et est capable de fournir du milieu hydraulique provenant d'un réservoir (10) à milieu hydraulique à une ligne hydraulique principale (11) de la boîte de vitesses (1), et une pompe électriquement entraînée (PE) qui peut être mue par un moteur électrique indépendamment dudit moteur (E) et est montée en série avec la pompe mécaniquement entraînée (PM), capable d'aspirer le milieu hydraulique de la ligne hydraulique principale (11).
