PROCESS AND DEVICE FOR ACTUATING A BRAKE MECHANISM BY A ROTATING ELECTRIC MOTOR

摘要

The actuating device of a braking mechanism comprises an electric driving motor and a gear pinion meshing with a first gear wheel integral with a screw screwed into a nut pressing on a plunger for application of the brake. The nut 13 carries a second gear wheel 22 having number of teeth which differs very slightly from that of the first gear wheel 31, for example by one tooth, to make a drive system with this first wheel in differential translation of the nut 13. Application to an electrically controlled and quick release brake.
