Abstract
A power steering system for a motor vehicle may include a servomotor, which drives an axially-movable rack via a ball nut. The ball nut may be mounted in a bearing such that the ball nut can be rotated in a housing. The ball nut engages with a threaded spindle formed on the axially-movable rack and has a ball screw thread on an inside thereof for balls to roll on. An external ball return means may connect a beginning of the ball screw thread to an end of the ball screw thread to allow endless circulation of the balls. A deflector and a sleeve may form a return channel of the ball return means.”
