The invention relates to a vehicle steering system with a superimposing actuator which superimposes the steering movements exerted using a steering handle with additional steering movements and which has a motor and a superimposing transmission designed as a harmonic drive transmission. The harmonic drive transmission has a rigid outer ring with an inner toothing into which a flexible inner ring with an outer toothing engages at two opposing points. The vehicle steering system is characterized in that the outer toothing of the flexible inner ring has between 54 and 66 teeth, in particular precisely 60 teeth, and the inner toothing of the rigid outer ring has precisely two more teeth than the outer toothing of the flexible inner ring. |
