The invention relates to a steering wheel unit for an electromechanical steering system of a motor vehicle, wherein the steering wheel unit comprises a force generating device for applying a mechanical feedback force to a steering wheel to feed back a current steering and/or driving state to a driver. The force generating device comprises two steering shaft nuts, two flanges, a first elastic element and a second elastic element, wherein the two steering shaft nuts are axially and adjustably arranged on an external thread section of the steering wheel shaft. Each steering shaft nut is matched with one of the flanges. The flanges are arranged around a first flange shaft and a second flange shaft in an axially adjustable manner, the first elastic element is arranged on the first flange shaft,and the second elastic element is arranged on the second flange shaft. The elastic elements can be deformed by an axial movement of the flanges, and the force generating device applies a force to thesteering wheel shaft so that a feedback force, which can be generated on the steering wheel, for feeding back a steering state dependent on a wheel steering angle to a driver increases with an increase in the adjustment of the steering wheel deviating from straight travel.
一种用于机动车的机电式转向系统的方向盘单元,其包括力产生装置,用于给方向盘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两个轴向可调节地布置在方向盘轴的外螺纹区段上的转向轴螺母、两个法兰、一个第一和第二弹性元件。每个转向轴螺母与所述法兰之一配合。所述法兰轴向可调节地围绕第一和第二法兰轴布置,所述第一弹性元件布置在所述第一法兰轴上并且所述第二弹性元件布置在所述第二法兰轴上。这些弹性元件能够通过所述法兰的轴向运动变形,所述力产生装置给所述方向盘轴加载力,使得随着方向盘偏离直线行驶的调节的增大,在该方向盘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反馈力上升。
