<p>A steering mechanism for a motor vehicle, comprising a worm gear which is engaged inside a worm (11). The worm has a movable bearing (13) on one end thereof. The movable bearing (13) needs to be movable in the direction of the worm gear in order to compensate erosion on the worm or worm gear with the aid of a hydraulic damper, requiring a minimum amount of clearance between the movable bearing (13) and a bearing bushing (20). Since the worm is very quickly moved back and forth during operation, the movable bearing (13) hits against the bearing bushing (20) as a result of said clearance, resulting in disturbing noise. The aim of the invention is to reduce said disturbing noise and to enable displacement of the movable bearing (13) in order to compensate for erosion. According to the invention, the movable bearing (13) can be clamped by a spring (21) inside a bearing bushing (20).</p> |
