An actuating device (1) for a disc brake (2) comprises: a piston (7); a first ramp-ball motion converter (100) having a first ramp portion (101) axially constrained and actuatable to rotate about an actuation axis (8), a second ramp portion (102) coupled to the piston (7), and a plurality of rolling elements (29) interposed in contact between ramp tracks (103) formed by the first ramp portion (101) and the second ramp portion (102); a second screw and nut motion converter (4) connected between the second ramp portion (102) and the piston (7); a torque limiter (10):-which effects a torsional connection of the first ramp part (101) and the second ramp part (102) such that they rotate together about the actuation axis (8) until a predetermined limiting torque is reached in said torsional connection,-when the predetermined limiting torque is exceeded, the first ramp part (101) and the second ramp part (102) are rotated together about the actuation axis (8), and-when the predetermined limiting torque is exceeded, the second ramp part (102) is rotated about the actuation axis (8). It decouples a rotation of the first ramp portion (101) about the actuation axis (8) relative to the second ramp portion (102).

    一种用于盘式制动器(2)的致动装置(1)包括:活塞(7);第一坡道‑滚珠运动转换器(100),其具有在轴向上被约束并且能够被致动成围绕致动轴线(8)旋转的第一坡道部分(101)、联接至活塞(7)的第二坡道部分(102)和以接触的方式被置于由第一坡道部分(101)和第二坡道部分(102)形成的坡道轨道(103)之间的多个滚动元件(29);连接在第二坡道部分(102)与活塞(7)之间的第二螺杆和螺母运动转换器(4);扭矩限制器(10):‑其实现第一坡道部分(101)与第二坡道部分(102)的扭转连接,使得它们围绕致动轴线(8)一起旋转,直至在所述扭转连接中达到预定限制扭矩为止,‑当预定限制扭矩被超出时,其将第一坡道部分(101)围绕致动轴线(8)相对于第二坡道部分(102)的旋转解耦。
