| 摘要 |
The present invention relates to a device for lubricating a step-up/down mechanical assembly (2), particularly a transmission gearbox, which comprises a reservoir (5A) of lubricating fluid (H) and a distribution circuit (8) capable of supplying lubricating fluid (H) from said reservoir (5A) to at least one element (11) of said assembly (2) that is to be lubricated. According to the invention, the distribution circuit (8) comprises at least one scoop (9), one end (9A) of which enters the reservoir (5A), the lubricating device (1A) comprises means (10A) for creating a relative movement between said end (9A) of the scoop (9) and the reservoir (5A), and said relative movement causes a dynamic effect in the lubricating fluid (H) such that it causes lubricating fluid (H) to enter the scoop (9) and causes it to flow through the distribution circuit (8).
