Abstract:
Device for limiting the force of a linear jack having a reversible screw/nut system with one element of the screw and nut system being rotated by a drive system and another corresponding element being translated accordingly and controlling translation of a load, the device comprising a first translated member integral with the translated element of the screw/nut system and a second member integral with a load activated in translation by the jack, said two members being able to rotate with respect to each other, and having a friction system disposed between said two members for ensuring: i) the linking of said two members when a torsion torque subjected to the friction system by the second member and by the first translated member is less than a predetermined value, and ii) the sliding of said two members when the torsion torque exceeds the predetermined value.
