Power steering, particularly power assisted steering system for vehicle, has motion screw that is driven by servo motor, where outer ring or inner ring of roller bearing is impinged with higher thermal expansion coefficient

摘要

The power steering (1) has a motion screw (3) that is driven by a servo motor (2). An outer ring (10) or an inner ring (11) of a roller bearing (9) or a component of a building panel (12) is impinged with a higher thermal expansion coefficient as the thermal expansion coefficient of the outer ring or inner ring with a force. The force is operated by thermal expansion of the building panel. The component of the building panel is operatively connected with the outer ring or the inner ring.
