Abstract: An electrically assisted, power steering system for motor vehicles having an input shaft (6) connected to a pinion shaft (2) by a torsionally elastic member (5) is supported in a steering housing (1) by a rolling bearing. The rolling bearing is formed as an elastic, flexible roller bearing (13), whose cylinder rollers (13.5, 13.6) have at least at one peripheral position an elastically deformable cylinder roller (13.6), having a diameter that is slightly greater than a diameter of the other cylinder rollers (13.5). In this way, an exact guidance of the input shaft (6) is achieved, so that the applied steering torque can be used accurately by an evaluation unit (15) for controlling the servo motor (7).

Abstract: In a linear guide for transmitting a torque between a tubular housing, rotatable about a longitudinal axis, and a shaft, received in the housing and movable in the direction of the axis in relation to the housing, a plurality of axial rolling bearings are received in the housing in surrounding relationship to the shaft. The axial rolling bearings are disposed in two radial planes in axial spaced-apart relationship, wherein the axial rolling bearings in each of the two radial planes have each two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing retained in the housing and defining a center axis which is shifted parallel at an offset to a normal upon a longitudinal shaft axis, while the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

Abstract: A play-free radial ball bearing, includes an inner bearing ring and two outer bearing rings which are disposed in spaced-apart relationship and define a common raceway. A spring element applies an axial force on one of the outer bearing rings to thereby press the outer bearing rings resiliently against one another. The outer bearing rings and the spring element are surrounded by a tolerance ring which is made of plastic material to provide a structural unit, whereby the tolerance ring has a shoulder on one end for radially surrounding the spring element and at least one retaining lug on another end for radially surrounding the other one of the outer bearing rings.

Abstract: A suspension strut used in a wheel suspension of an automotive vehicle, includes a shock absorber, a suspension strut bearing, and a coil spring at least partially coaxially surrounding the shock absorber and having one spring end supported by the shock absorber. The suspension strut bearing includes two plastic carrier elements, and a roller bearing positioned between the carrier elements. One carrier element is a guide ring connected to a vehicle body of the vehicle, and the other carrier element is a single-piece housing having incorporated therein plural hollow chambers in partial concentric surrounding relationship to the shock absorber and formed with a guide collar and a support surface for supporting the other end of the coil spring. The guide ring has a radially inner collar and a radially outer collar which together receive the roller bearing and extend at least beyond a midsection of the roller bearing.
