Rotational connection system provided with a free-wheel and a lubrication device

A method for lubricating the rotational connection system that is provided with a free-wheel, the free-wheel including a driving part and a driven part that are able to rotate about an axis of rotation, the free-wheel including at least one rotational link member arranged in a linking space, the linking space being located radially, relative to the axis of rotation, between a driving linking section of the driving part and a driven linking section of the driven part, the rotational connection system including a lubrication device for lubricating the free-wheel, the lubrication device including a lubricating fluid,

• wherein the method includes the following steps:
• during a disengaged operating mode of the free-wheel during which the driving part and the driven part are rotationally disengaged from each other about the axis of rotation, a fluid circulation device of the lubrication device is set in rotation, relative to a driving pumping section of the driving part, by speed differential between a driving speed of rotation, about the axis of rotation, of the driving pumping section and a driven speed of rotation, about the axis of rotation, of a driven pumping section constrained to rotate with the fluid circulation device, and the lubricating fluid is forced to move within the linking space at least under the influence of the fluid circulation device.
