The invention provides an actuating mechanism for a parking brake system, and the vehicle parking brake system. In the actuating mechanism, a lock plate is supported by a supporting piece fixed on a shell, and meanwhile, a limiting part formed by the supporting piece and/or the shell is used for clamping the lock plate from the two axial sides to limit the axial degree of freedom of the lock plate. Compared with the scheme that the platform part is in contact with the axial side face of the lock plate in the prior art, the contact area between the limiting part and the axial side face of the lock plate is greatly reduced, so that the contact point between the lock plate and a structure used for limiting the lock plate in the rotating process can be easily determined, and the friction force arm and the friction torque can be easily determined.

    本发明提供了一种驻车制动系统用致动机构及车辆驻车制动系统。在该致动机构中,锁板利用固定于壳体的支撑件支撑的同时,利用该支撑件和/或壳体形成的限位部从轴向两侧夹持锁板来限制锁板的轴向自由度。与现有技术中利用平台部与锁板的轴向侧面接触的方案相比,该限位部与锁板的轴向侧面之间的接触面积大幅缩小,使得容易确定锁板在转动过程中与用于限制锁板的结构之间的接触点,从而容易确定摩擦力臂和摩擦力矩的大小。
