Abstract: A steering system includes a steering rod mounted for longitudinal axial sliding in a housing and a steering motor acting on the steering rod via a ball screw drive, for which the steering rod forms a ball recirculation screw thread, which interacts with a transmission nut that can be driven by the steering motor. A transmission wheel of a flexible transmission, by means of which driving power of the steering motor is transmitted to the transmission nut, is untiltably connected to an inner ring of a rotary bearing. The transmission nut is pivotably mounted on the transmission wheel about an arbitrary pivot axis, which is oriented perpendicularly to the longitudinal axis of the steering rod. The transmission nut, which is pivoted as a result of a flexural load on the steering rod, can be decoupled from the rotary bearing and from a tensile load on the transmission wheel.
