The invention relates to an electromechanical actuator for a vehicle brake comprising a body () in which are arranged an electric motor () and a threaded plunger cooperating via a helical link with a nut () driven in rotation by the electric motor (). According to the invention, the nut () is mounted to move axially in the body () of the actuator between a rest position towards which the nut () is pushed back by elastic means, and an active position towards which the nut is displaced against the elastic means when a braking force is applied, the actuator further comprising means for detecting the axial displacement of the nut.

Electromechanical actuator for vehicle brake and braking system comprising such an actuator

An electromechanical actuator for a vehicle brake, the actuator comprising first and second portionsandthat are separable. The first portionincludes an electric motorand connection structurefor connecting the actuator to an external control structure. The second portionincluding a slidable pusher, the second portionalso including measurement structure. The first portionincludes a first antennaconnected to the connection structure, and the second portionincludes a second antennaconnected to the measurement structure, the two antennasbeing arranged to be electromagnetically coupled together when the first portionand the second portionare coupled together, so as to enable electrical signals to be transferred between the measurement structureand the connection structure

Electromechanical actuator for a brake

An aircraft electromechanical braking system comprising a braking control unitand at least one electromechanical brake, the brakebeing fitted with at least one electromechanical actuatorhaving a pushersuitable for being moved by means of an electric motor. The actuatoralso has a blocking memberfor blocking the pusherin position. The control unitis adapted to cause the braking system to operate in an additional braking mode referred to as 'combined' mode, in which the motoris activated to bring the pusherinto a position in which it exerts a given holding force, and then the blocking memberis activated, while activation of the motoris maintained.

System for maintaining a pressing force by the combined action of two members

An electric brake for an aircraft wheel comprising a supportformed by a torsion tubeand by an actuator-carrier, a stackof disks mounted around the torsion tube, electromechanical actuatorscarried by the actuator-carrier, each actuator comprising an electric motorand a pusher, the electric motorbeing adapted to move the pusherfacing the stackof disks in order to apply a braking force selectively to the stackof disks; and temperature measurement means for measuring a temperature representative of a temperature that exists in the stackof disks. The temperature measurement means comprises at least one temperature sensorarranged in the pusherof one of the electromechanical actuatorsso as to be located in the immediate proximity of the stackof disks when the pusheris brought into contact therewith.
