The invention relates to a servo-assisted steering system, in particular for a motor vehicle, having a servo motor which drives an axially displaceable component via a nut () which is mounted in a frame () in a rotatable manner in a bearing (), wherein the nut () engages with a threaded spindle () formed on the component and is supported via the bearing () elastically with respect to the frame () in the axial direction by means of spring elements () and is supported on the frame () in the radial direction along a narrow encircling contact surface (), wherein the spring elements () are corrugated springs.

Electromechanical motor vehicle steering system

Ball screw comprising a ball nut (), which is rotatably mounted on a threaded shaft and on the inner circumference of which at least one ball thread () wound around an axis () in a coil shape is provided for balls () to roll on, wherein at least one recirculating element (), which is arranged on the outer circumference of the ball nut () and which is provided with a recirculating channel for the balls (), connects a start of a coil to an end of a coil of the ball thread by means of the two ends of the recirculating element in order to enable endless recirculation of the balls (), wherein the ball nut () is provided with a flange () for fastening a belt pulley () and with a bearing seat (), and a sleeve () pushed onto the ball nut is provided with a perfectly cylindrical outer circumferential surface, which outer circumferential surface secures the recirculating element () on the ball nut () and surrounds the ball nut () in a tubular shape between the flange () and the bearing seat ().
