Abstract

A power-assisted steering system includes a gear mechanism, coupled to a steering column, with a gear and a mating gear. The two transmission gears have teeth (4, 5) via which they engage with each other, movement and power being transmitted from one gear to the other gear via effective profiles of their tooth faces (11, 12). In order to provide a gear mechanism that has an enhanced load-bearing capacity and at the same time can be manufactured in a simple and economical way, the effective profiles of the tooth faces (11, 12) of the gear and the mating gear contact over the height (h4, h5) of the teeth (4, 5).
