  • Patent number: 9080646
    Abstract: 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.

  • Patent number: 8646351
    Abstract: 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.

  • Publication number: 20130206497
    Abstract: 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.

  • Patent number: 8087830
    Abstract: Disclosed is a radially movable floating bearing for a shaft of a gear of a steering system, comprising a bushing or an inner ring or a rolling bearing, which is supported in a seat of a frame or housing of the gear. The inner ring or the bushing or the rolling bearing is held by at least one support element made of material having elastomeric properties which is inserted into a gap between the seat and the inner ring, the support element being designed as a pivot bearing. In order to provide a radially movable floating bearing for a steering system gear shaft, which is low-noise, easy to pivot and highly resilient, the pivot bearing cooperates with a damping stop disposed tangentially at a distance thereto, the stop being disposed at a radial distance from the inner ring or the seat.
