摘要

The servo steering system (1) has a driving screw (2) driven by a servomotor out of a nut (4) supported in a frame (3) in an axially undisplaced manner. An axially displaced component (5) is provided whose taper thread (6) is engaged with an internal thread (7) of the nut. A bearing (8) is provided for axial or radial support of the nut in the frame. A ring (9) of the bearing is integrally formed with the nut. The bearing is a radial bearing (10).
