Abstract
A free-wheel comprising a driving part and a driven part that are able to rotate about an axis of rotation, the free-wheel comprising at least one rotational connecting member arranged in a connection space, a driven connection section of the driven part surrounding a driving connection section of the driving part, the connection space being located radially, with respect to the axis of rotation, between the driving connection section and the driven connection section. The free-wheel comprises at least one barrier, the geometry of which varies depending on the speed of rotation of the driving part, arranged radially between the driving part and the driven part and longitudinally against the connection space, the barrier being constrained to rotate with the driving connection section.
