Abstract
An actuator (10) of a steer-by-wire steering device of a motor vehicle comprises a housing (46, 146), a spindle (42, 142) and a positionally fixed spindle nut (43, 143) mounted so that it can rotate, which within the housing (46, 146) form a spindle drive (41, 141) for the axial displacement of the spindle (42, 142) relative to the spindle nut. An inertial mass (100, 300, 400, 400a, 500, 600) is at least indirectly coupled to the spindle (142), taking into account the oscillation behavior of at least one component of the actuator (10), in particular the spindle (142).
Claims13
An actuator of a steer-by-wire steering device of a motor vehicle, comprising:
- a housing;
- a spindle drive with a spindle and a positionally fixed spindle nut rotatably mounted within the housing (46, 146) for the axial displacement of the spindle relative to the spindle nut;
- and
- an inertial mass fixedly coupled to the spindle at least indirectly, the inertial mass having a mass moment of inertia configured to at least dampen or prevent oscillation behavior of at least one component of the actuator.
