摘要

WHEEL BRAKE FOR A VEHICLE AND METHOD FOR CONTROLING THE ELECTRICAL POWER SUPPLY OF A NON-REVERSIBLE ELECTRICAL ACTUATOR FOR A WHEEL BRAKE OF A VEHICLE. The invention relates to a wheel brake for a vehicle, in particular for an aircraft, the brake comprising a support (2) which receives at least one electromechanical actuator (1) equipped with a friction element (8) impeller (8). 3) and movable by driving an electric motor (6) to selectively apply a braking force to the friction elements. According to the invention, the actuator is non-reversible, such that a reaction force applied to the booster cannot cause the electric motor to operate, and wherein the actuator is associated with devices (30, 31, 32, 33 34) to selectively turn off the electric motor power supply, the device of which allows power to be distributed to the actuator under normal circumstances, and to turn off the power supply if: - the measured rotation speed (sym ~ mes ~ ) the electric motor falls below a predetermined first threshold (S ~ 1 ~); and - the commanded rotational speed (sym) of the electric motor falls below a predetermined second threshold (S ~ 2 ~).
