    摘要： An electro-hydraulic actuator (1) for actuating a brake (2) with a hydraulic thrust unit comprises an electric motor (3), a converting mechanism (5) to convert a rotational motion of the motor (4) into a translational motion, a cylinder (8), and a piston (9) connected to the converting mechanism, wherein the converting mechanism (5) is configured so that, for a given angular speed of the drive shaft (4), the translation speed of the piston (9) decreases from a maximum value in a rear length (14) of the piston stroke to a minimum value in a front length (13) of the piston stroke.

    摘要： A locking device of an electromechanically-operated brake caliper for a disc brake, comprising a ratchet comprising a rotating element having at least one first cam and one first follower pushed elastically against said rotating element, configured to act in conjunction with said at least one first cam to allow the rotation of the rotating element in a first direction of rotation, and to prevent the rotation of the rotating element in a second direction of rotation, opposite to said first direction of rotation; a selector element sliding between a first selector element position and a second selector element position, said selector element being adapted to operate said first follower so that, in said first selector element position, said selector element keeps said first follower in a disengaged position away from the rotating element in which the application of a parking braking action is prevented, and so that, in said second selector element position, the selector element keeps said first follower in an engaged position in contact with said rotating element in which a parking braking action can be applied; said selector element having a second cam and said first follower having a first follower opening forming a second follower, said second cam being configured to act in conjunction with said second follower to operate said first follower between said engaged position and said disengaged position.
