Abstract
A superimposed steering system of a vehicle steering system, has an input shaft and an output shaft that are at least partially rotationally mounted on a support system fixed to the vehicle body, a servodrive comprising a rotor arranged in a coaxial manner in relation to one of the shafts and is connected in a rigid manner to a first transmission element and a locking device for selectively coupling the shafts. The first transmission element transmits the rotational speed of the rotor to the rotational speed of the input shaft, and the rotor is rotationally connected to a ferromagnetic or permanently magnetic first contact element. The coupling which is rotationally connected to the shafts can be obtained by a friction connection of a first contact element to a second contact element which is rotationally connected to the support system. The pressure force can be magnetically produced and at least one of both contact elements is arranged in a displaceable manner in the axial direction.
