초록 ▼

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.

대표청구항 ▼

A braking mechanism, comprising a plunger moving in translation to apply brake pads on at least one member to be braked, a nut able to press on the plunger during translation and disposed on a screw driven in rotation by a first gearwheel turning at a first rotational speed by means of an electric motor in order to move the nut and plunger at a first linear speed, characterized in that the mechanism comprises a second gearwheel driven by the motor and rotatable on the nut with which the second gearwheel is coaxial, means for connecting the second gearwheel and nut in rotatation as a result of loading transmitted by the plunger to the second gearwheel when the brake pads apply a load on the member to be braked, the nut and second gearwheel then being driven in rotation by the motor at a second rotational speed less than the first rotational speed in order to move the nut and plunger at a second linear speed proportional to the difference of the rotational speeds so as to effect an amplification of loading effected by the brake pads on the member to be braked, a pinion effecting simultaneous communication of the motor with the first and second gearwheels which are disposed coaxial to the screw, the number of teeth of the second gearwheel very slightly more than the number of teeth of the first gearwheel to permit coaxial rotation of the gearwheels despite the difference in the number of teeth, threading of the screw in the nut achieved by means of a member with reversible thread, a connection between the pinion and the screw via the first gearwheel comprising a clutch which is engageable during an application phase of braking and disengageable during a release phase of braking, during the release phase of braking the clutch permitting free rotation of the screw which is reversible, the screw rotating reversely due to the effect of reaction force exerted on the plunger, the motor rotating the pinion in the same rotational direction for both phases of braking and the clutch being alternately actuated and deactuated.
