Abstract: A steering column for a motor vehicle may include a casing unit in which a steering spindle is mounted rotatably about a longitudinal axis that extends in a longitudinal direction. The casing unit has at least two casing tubes that have a polygonal cross section and are guided such that they can be adjusted relative to one another in the longitudinal direction. Rolling bodies that have a rolling body radius are arranged between the casing tubes such that the rolling bodies can roll in the longitudinal direction in at least three raceways that are distributed circumferentially. To increase rigidity and improve compactness, center points of the rolling bodies are at a radial spacing that is less than or equal to the rolling body radius from an envelope circle that circumscribes the casing tube, on which the rolling bodies can roll on the outside.

Abstract: The present disclosure relates to a steering column, comprising: a first sleeve, a second sleeve and a gap elimination means. The first sleeve is received in the second sleeve in a telescopic way in a longitudinal direction. The gap elimination means includes an elastic pretensioning element and a wedge-shaped body, the wedge-shaped body having a first wedge-shaped surface and a second mating surface. The gap elimination means further comprises an intermediate element, the intermediate element having a third wedge-shaped surface which abuts the first wedge-shaped surface and has a shape fitted to the shape of the first wedge-shaped surface. The pretensioning element applies a pressing force to the wedge-shaped body via the intermediate element. The steering column according to the present disclosure is capable of stably maintaining a gapless state between the first sleeve and second sleeve, thus preventing noise.
