The invention relates to a steering wheel unit of an electromechanical steering system of a motor vehicle. The steering wheel unit comprises a force generating device for loading the steering wheel with a mechanical feedback force transmitted to a driver with respect to the current steering and/or driving state, and a steering movement sensor arranged in the region of the steering wheel axis of the steering wheel for sensing the position of the steering wheel. The force generating device comprise a straight torsion bar arranged along the steering wheel axis, the torsion bar is connected with the steering wheel at the end of a first end face and can be acted upon by first and second brake discs arranged for this purpose at the end of a second end face; and with the increasing adjustment, deviating from straight travel, of the steering wheel, a restoring force which increases with the angle of rotation of the steering wheel can be generated in a first stage and a constant restoring forcecan be generated on the steering wheel with a continuously increasing angle of rotation in a subsequent second stage in order to feed back a steering state dependent on the deflection of wheels to the driver.

    本发明涉及用于机动车机电式转向系统的方向盘单元。方向盘单元具有用于以传输给驾驶员的、关于当前转向和/或行驶状态的机械反馈力来加载方向盘的力产生器件和布置在方向盘的方向盘轴的区域中的转向运动传感器,其用于感测方向盘位置。力产生器件包括沿方向盘轴布置的直的扭力杆,扭力杆在第一端面的端部上与方向盘连接并且在第二端面的端部上能够被为此布置的第一制动盘和第二制动盘这样以力加载,使得随着方向盘的增大的、与直线行驶偏离的调节,首先能够在第一级别中在方向盘上产生随着方向盘的转角增大的的复位力并且在紧随其后的第二级别中能够随着继续增大的转角在方向盘上产生恒定的复位力,用于将与车轮偏转相关的转向状态反馈给驾驶员。
