Claims

Demands

1. Lubrication device (20) for speed reducer (1), the reducer (1) comprising a reduction device disposed in a housing (60) comprising a lubricating fluid, the reduction device comprising at least: - an input shaft (100) intended to be driven by a motor, in particular an electric machine, - a second shaft (120) coaxially carrying an input wheel of the differential (30), - an intermediate shaft (110) capable of transmitting a torque between the input shaft (100) and an input wheel of the differential (30), characterized in that the lubrication device (20) comprises at least two reservoirs (23, 24) for the lubricating fluid.

2. Lubrication device (20) according to claim 1, in which a first reservoir (23) is arranged to recover the dispersed lubrication fluid.

3. Lubrication device (20) according to claim 1 or 2, wherein the first reservoir (23) is held in place by the bottom of the housing (60) and a cover, for example by a system.

4. Lubrication device (20) according to any one of claims 1 to 3, wherein a second reservoir (24) is arranged to recover the lubricating fluid poured from the first reservoir (23).
