Abstract
The disclosure relates to a steering wheel actuator unit for a steer-by-wire steering apparatus for a motor vehicle and having a steering axle, wherein a free end of the steering axle is designed for arranging a steering wheel and the steering axle is rotatably mounted about its longitudinal axle, the steering wheel actuator unit comprising at least one feedback device which acts on the steering axle to realize a predetermined torque and/or a predetermined damping, and a spindle device connected to the steering axle for providing end stops for the rotational movement of the steering axle. In order to be able to reduce and/or avoid incorrect operation in case of failure of the feedback device, the steering wheel actuator unit further comprising an eddy current device which generates a resistance for the rotation of the steering axle about its longitudinal axle.
