Electromechanical power steering system with play compensation for the worm gear unit

摘要

The present invention relates to an electromechanical power steering system with an electric servomotor (1), which drives a worm shaft (2) with a on a steering shaft (8) which meshes arranged worm wheel (7), the worm wheel (7) with an input shaft of a steering gear is in operative connection, and wherein the worm shaft (2) and the steering shaft (8) in a common transmission housing (9) are rotatably supported, in which the worm shaft (2) a free motor distal end (12) which, in a roller bearing (13) with an inner ring (14), rolling elements (15) and an intermediate ring (16) is mounted, wherein the intermediate ring, an internal running surface for the rolling elements (15) and an external running surface for the outer rolling elements (17), and wherein the internal running surface and the external running surface of the intermediate ring (16) are arranged eccentrically to each other.
