Abstract
Ratchet free wheel device comprising a first element 1 provided with cavities 14, a number of ratchets 28 able to project into said cavities 14, and a second element 2 for supporting the ratchets 28 so that the second element 2 rotates as one with the first element 1 in one direction of relative rotation of said first and second elements and is free to rotate in an opposite direction of relative rotation. The device comprises a means of controlling the ratchets 28 which is capable of preventing them from projecting into said cavities 14 so that the second element 2 is free to rotate with respect to the first element 1 in two opposite directions of relative rotation of said first and second elements when said control means is active.
