Abstract

See full text

An electric power-assisted steering system of a motor vehicle comprises a helical pinion which engages into a helical gear. A reloading device comprises a reloaded pressure piece which presses the helical pinion into the toothing of the helical gear. The requirements of assembly are reduced and the elastically urging of the helical pinion or the worm need not be adjusted during assembly since the necessary elastically urging is automatically adjusted such that friction in the gearing is minimized, improved efficiency is achieved and the spring force can be held as constant as possible throughout the service life and unwanted noise development in the gearing can be largely reduced.
