摘要

The power steering (1) has a servomotor (2), which actuates a nut (5) supported in a frame (4) in axially undisplaceable manner. The nut is in contact with an outer thread (7) of an axially undisplaceable component (8). A traction drive (3) is provided, which has a transmission greater than certain ratio.
