The invention provides an actuating mechanism for a parking brake system. In the actuating mechanism, a magnet assembly can be mounted on the shaft in a manner of reciprocating along with the shaft along the axial direction of the shaft, and the circumferential limiting piece of the magnet assembly directly realizes an adaptive guide relationship with the guide piece fixed on the shell without passing through the shaft; the magnet assembly is not rotatable relative to the housing in the circumferential direction of the shaft (fixedly positioned relative to each other). Therefore, because the magnet assembly is directly clamped into the shell without the shaft, a size chain is prevented from being too long, and the problem that the relative fixed positioning position of the magnet relative to the shell is inaccurate or the effect is poor due to accumulative errors is solved; furthermore, when the magnet assembly synchronously and axially reciprocates along with the shaft, the magnet assembly can be axially guided by the guiding piece without obstacles through the circumferential limiting piece, and the magnet assembly is properly guided in the process of being installed on the shell and detached from the shell.

    本发明提供了一种驻车制动系统用致动机构。在该致动机构中,磁体组件不仅以能够随着轴沿着轴的轴向进行往复运动的方式安装于轴,而且磁体组件的周向限位件不经由上述轴而与固定于壳体的导向件直接实现适配导向关系,使得磁体组件在轴的周向上不能相对于所述壳体转动(彼此相对固定定位)。因此,由于磁体组件不经由轴与壳体直接卡接,避免了尺寸链过长,从而减轻了累积误差导致磁体相对于壳体的相对固定定位的位置不准确或效果不佳的问题;进一步地,当磁体组件随轴同步轴向往复运动时,磁体组件可藉由周向限位件被导向件无障碍地轴向导向,在磁体组件安装于壳体和从壳体拆卸的过程中被适当地引导。
