CONTINUOUSLY VARIABLE TRANSMISSION PROVIDED WITH A SET OF HYDRAULIC PUMPS |
摘要 |
<p>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).</p> |
