    • An electric screw actuator system, e.g. for an electrically driven and controlled steering device, comprises a screw actuator, an electric motor (2) engaging the screw actuator through a reduction gear mechanism (3), electronic operating means for operating the screw actuator electrically, and a mechanical back-up system for operating the screw actuator in the absence of electric power e.g. in the case of an electric power failure of in the case the electric power is switched off, maintenance, garage parking etc. The mechanical back-up system comprises a manually controllable operation member (4) and an electromagnetic coupling (6), said coupling disengaging the rotation member from the screw actuator in the case of nominal operation and availability of electric power, and engaging the rotation member with the screw actuator in the case of electric power failure.
    • 电动螺杆致动器系统,例如 对于电驱动和受控的转向装置,包括螺杆致动器,通过减速齿轮机构(3)接合螺杆致动器的电动机(2),用于电动操作螺杆致动器的电子操作装置和机械备用系统 用于在没有电力的情况下操作螺杆致动器,例如 在关闭电力的情况下,电力故障的情况下,维护,车库停车等。机械备用系统包括可手动控制的操作构件(4)和电磁联轴器(6),所述联接器 在额定运行和电力供应的情况下,将旋转构件从螺杆致动器分离,并且在电力故障的情况下将旋转构件与螺杆致动器接合。
