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

摘要

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.
