Abstract
Official abstract text for this publication.
The invention relates to a telescopable steering spindle having an inner spindle and an outer spindle, which are arranged coaxially in relation to one another and have an out-of-round cross section for torque transmission, wherein an intermediate space is provided between the outer spindle and the inner spindle, a sliding sleeve being arranged in the said intermediate space, wherein the sliding sleeve is provided with a surface structuring on at least one surface facing the inner spindle or the outer spindle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A telescopable steering spindle, comprising: an inner steering spindle of the teloscopable steering spindle; an outer steering spindle of the telescopable steering spindle, wherein the inner steering spindle and an outer steering spindle are arranged coaxially in relation to one another and have an out-of-round cross section for torque transmission, wherein an intermediate space is provided between the outer steering spindle and the inner steering spindle; and a sliding sleeve of the telescopable steering spindle arranged in the intermediate space, wherein the sliding sleeve comprises long-chain polymers and includes a surface structuring on at least one surface facing the inner spindle or the outer spindle, the surface structuring comprising broken-up chains of the long-chain polymers, wherein structured surface areas of the sliding sleeve are provided with indentations or recesses on a microscopic level, and are for lubricant retention wherein the sliding sleeve is calibrated to a profile of the inner steering spindle, and wherein the indentations or recesses are a result of the calibration to the profile of the inner steering spindle. 2. The telescopable steering spindle according to claim 1 , wherein indentations or recesses comprise rolled indentations or recess.
