An actuating device (1) for a brake disc (2), comprising: a circulating ball screw-nut screw assembly (3), where the circulating ball screw-nut screw assembly (3) comprises a threaded shaft (4) and a nut screw (5) externally screwed onto the threaded shaft (4), where the thrust bearing (8) is mounted on the threaded shaft (4), where the thrust bearing (8) is mounted on the threaded shaft (4). The threaded shaft (4) and the nut screwing portion (5) extend in a direction of an actuation axis (6) coaxial with the threaded shaft (4), and wherein the threaded shaft (4) extends between a front end and a rear end of the threaded shaft (4), and wherein the nut screwing portion (5) is configured to receive a torque generated by a gear motor (7), and rotation of the nut screw (5) relative to the threaded shaft (4) causes the threaded shaft (4) to translate relative to the nut screw (5) in the direction of the actuation axis (6), the thrust bearing (8) providing a reaction stop for the nut screw (5) in the direction of the actuation axis (6), and the thrust bearing (8) being positioned within an extension of the threaded shaft (4) and between the front and rear ends of the threaded shaft (4).
一种用于制动盘(2)的致动装置(1),包括:循环式滚珠丝杠‑螺母旋拧部组件(3)、推力轴承(8),其中,循环式滚珠丝杠‑螺母旋拧部组件(3)包括螺纹轴(4)和在外部旋拧到螺纹轴(4)上的螺母旋拧部(5),其中,螺纹轴(4)和螺母旋拧部(5)沿与螺纹轴(4)同轴的致动轴线(6)的方向延伸,以及其中,螺纹轴(4)在螺纹轴(4)的前端部与后端部之间延伸,其中,螺母旋拧部(5)构造成接收由齿轮马达(7)产生的扭矩,以及螺母旋拧部(5)相对于螺纹轴(4)的旋转导致螺纹轴(4)相对于螺母旋拧部(5)沿致动轴线(6)的方向平移,推力轴承(8)在致动轴线(6)的方向上为螺母旋拧部(5)提供反作用歇止部,且推力轴承(8)定位在螺纹轴(4)的延伸部内并且位于螺纹轴(4)的前端部与后端部之间。
