摘要： A longitudinal displacement unit includes a first shaft element including an outer face having a plurality of first grooves and a second shaft element having a through-bore that receives the first shaft element. The second shaft element has a plurality of second grooves opposite the first plurality of grooves. A sleeve-shaped cage is disposed between the first shaft element and the second shaft element for guiding rolling contact members that engage the first plurality of grooves and the second plurality of grooves. The cage is provided with through-apertures that are circumferentially distributed, extend parallel to the longitudinal axis, and include longitudinal ends. Pressure springs are disposed within the through-apertures and are loaded between the longitudinal ends thereof. At least one stop is associated with one of the shaft elements, against which the pressure springs abut after having passed through a free displacement path of the cage between the two shaft elements, which free displacement path is not loaded by the pressure springs.

摘要： A telescoping steering column assembly includes lower and upper jackets having inner and outer surfaces, respectively, disposed with respect to one another in telescoping relationship. The telescoping steering column assembly includes a linear bushing disposed between the inner surface of the upper jacket and the outer surface of the lower jacket, that includes a plurality of convolutions disposed axially in side-by-side relationship as viewed in cross-section to provide outer and inner load bearing surfaces to engage the upper and lower jackets and to provide radial walls for flexing to maintain the bearing surfaces in engagement with the jackets to allow the bushing to radially expand and contract. The present invention provides the length-wise grooves formed by the convolutions to allow for reservoirs for lubricant solution to help reduce friction between the jackets, wherein the convolutions are elastically deformed to adapt to the annual clearance between the jackets.

摘要： A hand-guided working tool has a telescopic rod with a first and a second end. A drive motor is connected to the first end of the telescopic rod. A working tool, connected to the second end of the telescopic rod, is driven by the drive motor. The telescopic rod includes an outer tube and an inner tube inserted with an inner end into the outer tube and displacable in the longitudinal direction of the telescopic rod. A first clamping member is connected to the first end of the outer tube for fixing the axial position of the inner tube. The inner tube has an outer mantle surface and the outer tube has an inner circumferential surface. The outer mantle surface is spaced at a radial distance from the inner circumferential surface. A first cylindrical bearing body is supported on the inner end of the inner tube. The first bearing body is displacably supported in the outer tube. The first clamping member has an inner circumferential guide surface matching the outer mantle surface of the inner tube such that the inner tube is secured coaxially relative to the outer tube by the first clamping member and the first bearing body.

摘要： A telescopic shaft useful, for example, on an automobile steering assembly includes an external sleeve and an internal bolt within the sleeve and axially extending rows of rolling elements in respective axially extending raceways for defining the axial bearing between the bolt and the sleeve. The disclosure concerns a cage for the bearing which is comprised of resilient wire and includes a pair of yokes at the axially opposite ends of the rows of rollers, and the yokes are held together by lengths of wire at their circumferential ends. The yokes are of a circumferential length so as to cover the axial ends of the rows of rollers, whereby the yokes generally extend over more than 180.degree.. One cage yoke includes radially directed extensions which extend into a borehole in the bolt or the sleeve. The one yoke is interrupted intermediate its arcuate length and the extensions are defined at the interruption.
