Abstract: A power assisted steering system may include a threaded spindle that engages in a spindle nut, extends in a direction of a spindle axis, and is axially displaceable in a housing; and a drive unit having a gearwheel that is connected to the spindle nut in a rotationally fixed manner, can be driven rotatably about the spindle axis, and is rotatably mounted in the housing in a bearing arrangement. The bearing arrangement may have at least one bearing outer ring that is axially supported on the housing at an end face via a spring element, that is received coaxially in a sleeve element, and that is held radially in the housing. The spring element may be formed as a spring portion, and the sleeve element may be formed as a sleeve portion that is connected in one piece to the spring portion, on a one-piece carrier sleeve.

Abstract: An electromechanical power steering device may include a servomotor that drives an axially movable component via a ball nut mounted in a bearing such that the ball nut can be rotated about a longitudinal axis in a housing. The ball nut may be engaged with a threaded spindle configured on the axially movable component. The ball nut may include a ball screw on its inner side for balls to roll on, and an external ball return means that connects a start of the ball screw to an end of the ball screw to make endless circulation of the balls possible. A return channel of the ball return means may be formed by way of a deflecting body and a pulley wheel.

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.

Abstract: An electromechanical servo-assisted power steering system may include a servo motor that drives an axially displaceable structural element by way of a ball nut that is rotatably supported in a bearing in a housing. The ball nut may be engaged with a threaded spindle constructed on the axially displaceable structural element. The bearing may be a dual-row angular ball bearing having at least one bearing inner ring and at least one bearing outer ring. The at least one bearing outer ring may be received in a sleeve that is arranged in a bearing seat of the housing.

Abstract: An electromechanical power steering device, which may be used in a motor vehicle, may include a servomotor that drives an axially movable component via a ball nut that is mounted in a bearing such that the ball nut can be rotated in a housing. The ball nut may be engaged with a threaded spindle that is configured on the axially movable component. The bearing may be a double-row angular contact ball bearing with a single-part bearing inner ring. In some cases contact angles of the double-row angular contact ball bearing may be configured such that a supporting spacing other than zero is formed.
