    • 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.

    • A bearing is provided including a first part provided with a first coil (4) and a second part rotatable with respect to the first part about a bearing axis and being provided with a second coil which is electromagnetically coupled to the first coil. The first and second coil are magnetically enclosed by a first covering and a second covering, respectively. The first covering is fixed to the first part and the second covering is fixed to the second part. An air gap is formed between facing ends of the first and second coverings, with at least one of the facing ends of the first and second coverings being provided with at least one recession, such that the air gap varies when the first part and second part rotate with respect to each other. This may be used to provide an indication of speed (bearing rotation) without further sensors. Next to contactless transmission of power or data signals, the coupling between the first and second coil vary to provide a signal representative of the relative rotational speed of the first part of the bearing with respect to the second part.
    • 提供一种轴承,其包括设置有第一线圈(4)的第一部分和相对于第一部分绕轴承轴线旋转的第二部分,并且设置有与第一线圈电磁耦合的第二线圈。 第一和第二线圈分别由第一覆盖物和第二覆盖物包围。 第一覆盖件固定到第一部分,第二覆盖物固定到第二部分。 在第一和第二覆盖物的相对端部之间形成气隙,其中第一和第二覆盖物的至少一个面向端部设置有至少一个凹部,使得当第一部分和第二部分 相对于彼此旋转。 这可以用于提供速度(轴承旋转)的指示,而不需要其他传感器。 在电力或数据信号的无接触传输之后,第一和第二线圈之间的耦合变化,以提供表示轴承的第一部分相对于第二部分的相对转速的信号。
