The invention relates to an electro-hydraulic actuator (100) for actuating a brake caliper. The actuator comprises: an electric motor (1) with a drive shaft (2); a transforming mechanism (3) to transform a rotary motion of the drive shaft into a translational motion of a translatable portion configured to act on a hydraulic master cylinder of said brake; a first housing (5) to accommodate the transforming mechanism and support a second housing of the electric motor. Such a transforming mechanism includes a reduction gear (6; 36) configured to demultiply the rotary motion of the drive shaft. The reduction gear comprises a crown (12; 32) with inner toothing in one piece and rotationally locked. The actuator is characterized in that the crown comprises a front portion (42; 62) 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 so as to achieve 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 (X) of the reduction gear.

    本发明涉及一种用于致动制动钳的电动液压致动器(100)。该致动器包括:具有驱动轴(2)的电动机(1);转换机构(3),用于将驱动轴的旋转运动转换成可平移部分的平移运动,该可平移部分被构造成作用于所述制动器的液压主缸;第一壳体(5),用于容纳转换机构并支撑电动机的第二壳体。这种转换机构包括被构造成使驱动轴的旋转运动递减的减速齿轮(6;36)。减速齿轮包括具有内齿的冠状件(12;32),该冠状件成单件且被旋转地锁定。该致动器的特征在于,冠状件包括:前部部分(42;62),该前部部分直接地形状耦接至并插入电动机的第二壳体;以及一连接部,该连接部与转换机构的第一壳体成一体,以便实现电动机和减速齿轮之间相对于驱动轴的轴线以及相对于减速齿轮的中心轴线(X)的精确定中心。
