The invention relates to a steering wheel unit (1) of an electromechanical steering system of a motor vehicle (10) and to the electromechanical steering system, provided with the steering wheel unit (1), of the motor vehicle (10). The steering wheel unit (1) has a force generating means for loading a steering wheel with a mechanical feedback force to a driver in relation to the current steering state and/or driving state; a force generating means has a cam unit (16a, 16b), an elastic element (15) and a preload mechanism (11, 12, 13), wherein the elastic element (15) is arranged between the camunit (16a, 16b) arranged on a steering wheel shaft (3) and a preload mechanism (11, 12, 13) and can be deformed by an axial movement of the cam unit (16a, 16b). The force generating means loads the steering wheel shaft (3) with the force, and with the increasing adjustment, deviating from straight travel, of the steering wheel, an increased restoring force can be generated on the steering wheel,so as to feed back a steering state dependent on the deflection of wheels to a driver.
本发明涉及一种用于机动车(10)的机电式转向系统的方向盘单元(1)和用于机动车(10)的具有这种方向盘单元(1)的机电式转向系统。方向盘单元(1)具有力产生器件,其用于以给驾驶员的、关于当前的转向状态和/或行驶状态并且机械反馈力来加载方向盘。力产生器件具有凸轮单元(16a,16b)、弹性元件(15)和预紧机构(11,12,13),其中,弹性元件(15)布置在在方向盘轴(3)上布置的凸轮单元(16a,16b)与预紧机构(11,12,13)之间并且能通过凸轮单元(16a,16b)的轴向运动发生变形。力产生器件这样以力加载方向盘轴(3),使得随着方向盘的增大的、与直线行驶偏离的调节能在方向盘上产生增大的复位力用于将与车轮偏转相关的转向状态反馈给驾驶员。
