FREE WHEEL CLUTCH MECHANISM Russian patent published in 2011 - IPC F16D41/12 

FIELD: machine building.

SUBSTANCE: free wheel clutch mechanism consists of case with front and back covers, of ratchet disk or unit of ratchet disks, of cassettes with spring-loaded triggers in them and of feed spring. Uniformly distributed grooves are made on internal surface of the case along its axis. The cassettes with the spring loaded triggers are installed in a slot of the case by several in a row axially travelling under influence of feed springs. Row travel is restricted with overlap between the trigger of the first cassette of each row and a cut in the front cover. Only triggers of the first cassette of each row interact with the ratchet disk; the triggers of the following cassettes are located on projecting cylinder part of the back cover and are not actuated. In case of breakage the trigger interacting with the ratchet disk will be withdrawn from the case together with its cassette. The next cassette of the row with the spring loaded trigger will replace the cassette withdrawn from the case; also, the trigger is immediately turned into operation.

EFFECT: increased service life of mechanism.
