    摘要： An electromechanical brake caliper (9) includes a caliper body (10) and an electromechanical actuator (11). The electromechanical actuator includes a screw (14) and a nut screw (16) coupled to it, so that the nut screw (16) engages a movable thrust element (18, 32) by coupling surfaces (C, C′ and CIV) that cooperate with each other in the thrust relationship. This configuration allows oscillation of the relative nut screw (16) with respect to the movable thrust element (18, 32) about a single transverse axis (k), impeding the relative rotation between the nut screw (16) and the piston (18) about a longitudinal axis (y) of the thrust element.

    摘要： An electro-hydraulic actuator for actuating a brake caliper may have an electric motor with a drive shaft, a transforming mechanism and a first housing to accommodate the transforming mechanism and support a second housing of the electric motor. The transforming mechanism may include a reduction gear to demultiply the rotary motion of the drive shaft. The reduction gear may have a crown with inner toothing in one piece and that is rotationally locked. The crown may have a front portion directly shape-coupled to and inserted in the second housing of the electric motor and a connection integral with the first housing of the transforming mechanism for a precise centering between the electric motor and the reduction gear with respect to the axis of the drive shaft and with respect to a central axis of the reduction gear.
