The present invention relates to a disengageable (disconnectable) freewheel comprising an axle (10) and a ring (12), the ring being able to rotate only in one free predetermined direction with respect to the axle. According to the invention, the freewheel comprises a gear motor unit (18) for driving the axle (10) in rotation in the opposite direction to the predetermined direction, and this results in the fact that the ring (12) can rotate at most as quickly as the axle in the opposite direction to the predetermined direction. <IMAGE> |
