1. A steering system for a motor vehicle, comprising a steering wheel actuated by a driver and hydraulically positively coupled to steered vehicle wheels, a hydrostatic master unit mechanically drive-connected to the steering wheel, a hydrostatic slave unit mechanically drive-connected to the steered vehicle wheels, the master and slave units being hydraulically positively coupled to one another via hydraulic lines to form a hydraulic positive coupling, and a servo system, separate from the hydraulic positive coupling, arranged to be controlled as a function of the forces or torques transmitted between the steering wheel and the master unit, wherein springs are sized and operatively arranged to load the master unit into a central position, wherein the hydraulic positive coupling is under hydraulic preloading at least one line of the hydraulic lines between the master and slave units is connected to a hydraulic accumulator via a nonreturn valve opening in the direction of the at least one line.
