The invention relates to shipbuilding and power engineering. A disconnection clutch has a driving shaft on which the driving half-clutch of forward motion is rigidly fixed, a movable half-clutch, this is installed on slide bearings, a ratchet mechanism, this has ratchets and a ratchet ring, a screw pair (screw and nut), a driven half-clutch of forward motion, this is rigidly fixed at the screw of the screw pair, and a thrust rolling bearings. According to the invention the disconnection clutch additionally includes a reverse motion clutch and a control ring. The reverse motion clutch comprises a driving half-clutch of reverse motion with inner coupling teeth, this is arranged as one piece with the driven half-clutch of forward motion. On the driving half-clutch of forward motion ratchets are rigidly fixed, the movable half-clutch is made with inner coupling teeth placed in sectors uniformly in circle with one tooth in each sector, and there are rigidly fixed the ratchet ring and the nut of the screw pair, the driven half-clutch of forward motion is made with outer coupling teeth placed in sectors uniformly in circle with one tooth in each sector. The driving half-clutch of reverse motion is made with inner coupling teeth placed uniformly in circle, the driven half-clutch of reverse motion is made with outer teeth placed in sectors uniformly in circles as well, and in the placeswhere the teeth are not present fixation slats are rigidly fixed. The control ring is installed with possibility of motion on movable half-clutch and is connected to the support slide bearings. Those features of the invention provide implementation of disconnection clutch as reverse with force transfer at front and reverse motion at simultaneous increase of reliability and durability of the appliance.
