The invention relates to a feedback actuator (5) for a motor vehicle steering system (1), comprising a driving wheel (53) drivable by an electric motor (51) for rotation about a drive axis (M) and a driven wheel (54) in driving engagement with the driving wheel by a circulating belt (55), the driven wheel being connected to a steering shaft (22), the steering shaft is spaced apart from the drive axis (M) and is rotatably mounted about the steering axis (L), and the feedback actuator comprises a rotational angle detection device (7) having a first electrical position sensor (72) corresponding to the drive wheel (53), a second position sensor (75) corresponding to the driven wheel (54), and a circuit board (73, 76) carrying the position sensors (72, 75). In order to achieve an improved rotational angle detection device that is less susceptible to interference, the invention proposes that the printed circuit board (73, 76) have a first printed circuit board section (73) carrying the first position sensor (72), which is connected in a spatially displaceable and electrically conductive manner to a second printed circuit board section (76) carrying the second position sensor (75) by means of a flexible conductor element (77).
本发明涉及一种用于机动车辆转向系统(1)的反馈致动器(5),包括可由电动马达(51)驱动以绕驱动轴线(M)旋转的驱动轮(53)和通过环绕的皮带(55)与该驱动轮传动啮合的从动轮(54),该从动轮与转向轴(22)连接,该转向轴与驱动轴线(M)间隔开并且绕转向轴线(L)可旋转地支承,并且该反馈致动器包括转动角度检测装置(7),其具有与驱动轮(53)对应的第一电位置传感器(72)、与从动轮(54)对应的第二位置传感器(75)和承载位置传感器(72、75)的电路板(73、76)。为了实现改进的、更不易干扰的转动角度检测装置,本发明建议,电路板(73、76)具有承载第一位置传感器(72)的第一电路板区段(73),其通过柔性的导体元件(77)在空间上可移位地并且导电地与承载第二位置传感器(75)的第二电路板区段(76)连接。
