The invention relates to a steering wheel unit (1) for detecting a steering movement of a steering wheel (4) of an electromechanical steering system of a motor vehicle in a sensing manner, wherein thesteering wheel unit comprises a steering movement sensor (21) arranged in the region of a steering wheel shaft (3) of the steering wheel (4) and used for detecting a steering wheel position, and a force generating device used for loading mechanical feedback force to the steering wheel (4) so as to feed back the current steering and/or driving state to a driver. The force generating device comprises a steering shaft nut (11) which is arranged axially adjustably on an external thread section (10) of the steering wheel shaft (3), the steering shaft nut (11) is acted on by at least one linear spring (16a, 16b) coaxially arranged with the steering shaft nut at the end side, so that a return force, which can be generated on the steering wheel (4), for feeding back a steering state dependent ona wheel steering angle to a driver increases with an increase in the adjustment of the steering wheel (4) deviating from straight travel.
本发明涉及一种用于以传感方式检测机动车的机电式转向系统的方向盘(4)的转向运动的方向盘单元(1),其包括:布置在该方向盘(4)的方向盘轴(3)的区域中的转向运动传感器(21),用于检测方向盘姿态;以及力产生装置,用于给该方向盘(4)加载机械反馈力以向驾驶员反馈当前的转向和/或驾驶状态。所述力产生装置包括轴向可调节地布置在该方向盘轴(3)的外螺纹区段(10)上的转向轴螺母(11),该转向轴螺母在端侧由分别至少一个与其同轴布置的线性弹簧(16a,16b)加载力,使得随着方向盘(4)偏离直线行驶的调节的增大,在方向盘(4)上所能产生的用于向驾驶员反馈与车轮转向角相关的转向状态的复位力上升。
