Patent ID: 8646351

Claim:
Helical gearing for a steering system of a motor vehicle comprising a helical pinion which engages into a helical gear, a preloading device that has a preloaded pressure piece, which presses the helical pinion into toothing of the helical gear wherein: a) the preloading device comprises a housing part which has a section having an internal thread in which a readjusting element is screwed, wherein the readjusting element is loaded with a force in the direction of the pressure piece by way of a readjusting spring, b) the pressure piece is guided by way of a guide contour in the housing part so that it is axially displaceable between the helical pinion and the readjusting element, c) a preloading means which is disposed between the readjusting element and the pressure piece is provided and presses the pressure piece against the helical pinion, and d) the pressure piece comprises guide components which engage in an axially movable manner into axially extending guide sections of a guide contour of the readjusting element, wherein the guide components exit the axially extending guide sections in the direction of the helical pinion when the distance between the pressure piece and the readjusting element exceeds a defined value.
