ABSTRACT:
The invention relates to a switchable freewheeling ratchet unit 1a having a coupling sleeve 2 and a coupling hub 5 as well as radially resilient locking ratchets 13 and 38 per direction of rotation, which engage recesses 11 and 39 of the coupling hub 5 and which, depending on the direction of rotation, may be disengagable from the coupling hub 5 by a control ring 23 with control elements 21. The control elements 21 have first control faces 19, 19a and the locking ratchets 13 and 38 have second control faces 18, 18a facing the first control faces 19 and 19a for freewheeling purposes. The locking ratchets 13 or 38 not serving torque transmitting purposes are completely disengaged from the recesses 11 and 39, respectively, and are out of contact with the coupling hub.
