Abstract: The invention relates to an electromechanical brake actuator for an aircraft wheel, comprising an electric motor (2) with a stator (3) and a rotor (4), a screw/nut assembly, of which one of the elements is rotationally driven by the motor and the other of the elements is compelled to slide without rotation to selectively exert a force on a stack of discs, the actuator comprising a park blocking member (10) suitable for selectively blocking the rotor of the motor at least when the sliding element exerts a force on the stack of discs. The park blocking member comprises a shuttle (17) that can move between a stable position of blocking of the rotor of the motor and a stable position of freeing the latter under the action of a pulse actuator (22, 24, 25) switching the shuttle from one position to the other, the brake actuator comprising means (9, 18) for forcing the shuttle to the freeing position when the motor of the brake actuator is powered.

Abstract: The invention relates to an electromechanical actuator for a vehicle brake comprising a body (4) in which are arranged an electric motor (5) and a threaded plunger cooperating via a helical link with a nut (8) driven in rotation by the electric motor (5). According to the invention, the nut (8) is mounted to move axially in the body (4) of the actuator between a rest position towards which the nut (8) 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.

Abstract: The invention relates to a latching box for selectively retaining a movable element such as an undercarriage or a hatch in position, the box comprising a body carrying: a hook pivotally mounted about a first pivot axis between an engaged position and a disengaged position relative to the movable element; a locking member pivotally mounted about a second pivot axis parallel to the first pivot axis to pivot between a position for blocking the hook in the engagement position and a release position for releasing the hook; and at least one cam actuator in which the cam co-operates operationally with the locking member to move it towards the release position. The cam of the actuator is a cylindrical cam mounted to rotate about an axis of rotation orthogonal to the first and second pivot axes.
