<p>The invention relates to a brake (14) for a vehicle wheel (10) which is mounted in such a way that it can be rotated in relation to a wheel support (12), said brake comprising a frame (25) which is fixed to the wheel support (12), and additional mobile and fixed friction elements (20, 22). The inventive brake also comprises a device (15) for measuring a parameter representing the energetic capacity of the brake. Said measuring device (15) comprises a capacitive sensor (40) and an information processing unit (42), the capacitive sensor (40) comprising two measuring reinforcements (44) mounted face-to-face and carried by the frame (25), and a dielectric screen (46) carried by a friction element (20, 22) which can be displaced by the action of each actuator. The dielectric screen (46) slides between the two reinforcements during the clamping of the friction elements (20, 22) in order to modify the capacity of the condenser formed by the two measuring reinforcements (44). The invention also relates to the use of said brake in an aeroplane.</p> |
