  • ACTUATOR OF A STEER-BY-WIRE STEERING DEVICE OF A MOTOR VEHICLE AND METHOD FOR ASSEMBLING AN ACTUATOR OF A STEER-BY-WIRE STEERING DEVICE
    Publication number: 20230331289
    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).

  • Actuator with a spindle drive and rear-axle steering system
    Patent number: 11248689
    Abstract: Actuator having a spindle drive (1) for a rear wheel steering system, including a spindle (2) with a spindle thread (2a) and a spindle nut (3) with a nut thread (3a). The spindle thread (2a) and the nut thread (3a) are designed as displacement threads and the spindle nut (3) threadedly engages with the axially displaceable spindle (2) by way of the displacement thread. The spindle thread (2a) and the nut thread (3a) are braced against one another, in the longitudinal direction of the spindle (2), by a bracing element (4). The bracing element (4) is in the form of a threaded ring having an internal thread (4a) which engages with the spindle thread (2a). The threaded ring (4) is supported relative to the spindle nut (3) by at least one spring element (5, 6), and the at least one spring element (5, 6) is made of an elastomer.
