Abstract
A steering system has a steering rod longitudinally displaceable in a housing and a steering motor acting on the steering rod via a ball screw drive. The steering rod has a recirculating ball thread interacting via spherical transmission elements with a transmission nut driven by the steering motor and that is rotatably mounted by a bearing arrangement with a pivot bearing having an inner ring to which a mechanism wheel is fixedly attached. The transmission nut is pivotably mounted on the mechanism wheel about a pivot axis oriented perpendicularly to the longitudinal axis of the steering rod, and has a curved joint section which interacts with a curved joint section of the mechanism wheel to form a pivoting bearing. An elastically deformed spring ring arranged between the joint sections provides freedom from play of the pivoting joint.
