Claims

Claim

1. A safety friction clutch comprising a driving and driven half coupling coupled by means of a driven friction disk placed between a thrust disk rigidly connected to the driving half coupling and a pressure disk freely spring-loaded on this half coupling, 'and a release device including rolling elements in the form of balls placed in the nests of variable depth of the thrust disk and in the recesses of the pressure plate, characterized in that, in order to reduce the level of dynamic loads in transition If the clutch operates, it is equipped with an operation moderator mounted on the leading coupling half with the possibility of interaction in the axial direction with the pressure disk, in which the recesses are made through, and the rolling bodies located in them are axially spring-loaded relative to the moderator.

2. Coupling in π. 1, characterized in that the moderator is made in the form of a housing mounted with the possibility of movement relative to the leading coupling half, and a piston located in this housing, rigidly connected with the coupling half and dividing the housing into two cavities filled with a liquid or gaseous working fluid, while between the end face the housing facing the balls and the piston has a compression spring, and the cavity of the moderator are communicated by means of a throttle device.

3. The clutch according to claim 2, characterized in that the throttle device is adjustable.
