摘要： An electric power-assisted steering system of a motor vehicle comprises a helical pinion which engages into a helical gear. A reloading device comprises a reloaded pressure piece which presses the helical pinion into the toothing of the helical gear. The requirements of assembly are reduced and the elastically urging of the helical pinion or the worm need not be adjusted during assembly since the necessary elastically urging is automatically adjusted such that friction in the gearing is minimized, improved efficiency is achieved and the spring force can be held as constant as possible throughout the service life and unwanted noise development in the gearing can be largely reduced.

摘要： A thrust device, in particular for a roller cam mechanism in a steering system, includes a first mechanism member which is held on a frame in engagement with a second mechanism member. The thrust device comprises a pressure piece which is mounted on the frame so as to be displaceable along an axis and is acted on by a spring element for pressing the first and second mechanism members against one another. In order to construct the thrust device for compensating for wear and thermal expansion of the engagement of the mechanism members and to configure it to be inexpensive and quiet during operation, there is provision for the spring element to be formed from rolling bodies which are spring loaded approximately transversely with respect to the axis of the pressure piece, the rolling bodies being supported on oblique surfaces between the pressure piece and a frame part which is configured as a setting screw or cover. The pressure piece can additionally be spring loaded axially by a compression spring.

摘要： A helical gear mechanism for a steering system in a motor vehicle comprises a helical pinion which engages with a helical gear and a bearing bushing which accommodates a bearing of the helical pinion. An inner ring of the bearing bushing is connected to an outer ring via a pivot bearing so that a pivoting motion of the helical pinion relative to the helical gear is possible. A pressure piece is disposed between the inner ring and the outer ring of the bearing bushing. The pressure piece is movable in a spring-loaded manner in a section of an annular gap between the inner ring and the outer ring. The inner ring and/or the outer ring are designed in the section so that the annular gap between the inner ring and the outer ring is tapered in the direction in which the pressure piece can be moved in a spring-loaded manner.

摘要： Helical gearing for a steering system of a motor vehicle comprises a helical pinion which engages a helical gear. Minimization of friction in the gearing and increased efficiency since continuous elastically urging with an approximately consistent spring force during the entire service life is attained. It is not necessary for a very large spring force to be applied. By way of the continuous elastically urging with an approximately consistent spring force, clattering noises or disturbing noises are prevented or largely reduced throughout the entire service life. Due to the simple design the requirements on assembly are reduced. It is advantageous that the elastically urging of the helical pinion or the worm need not be adjusted during assembly since the necessary elastically urging is automatically adjusted.
