BALL SCREW DRIVE OF AN ELECTROMECHANICAL SERVO-ASSISTED POWER STEERING SYSTEM HAVING INTEGRATED ANGULAR BALL BEARING AND COMPENSATION FOR DIFFERING THERMAL EXPANSION

摘要

The invention relates to an electromechanical servo-assisted power steering system (1), in particular for a motor vehicle, having a servo motor (9), which drives an axially displaceable component (6) via a ball nut (13), which is rotatably mounted in a bearing (15) in a housing (21), wherein the ball nut (13) engages with a threaded spindle (6') formed on the component (6), wherein the bearing (15) is a two-rowed angular ball bearing having at least one bearing inner ring (16) and at least one bearing outer ring (18), and wherein the at least one bearing outer ring (18) is accommodated in a sleeve (19), which is arranged in a bearing seat (20) of the housing (21).
