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.

Steering column

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.

The steering shaft is rotatably mounted about a longitudinal axis in a casing unit. A feedback actuator may be operatively coupled to the steering shaft. The casing unit may have a second length in a direction of the longitudinal axis, and the steering shaft may project into the casing unit by a first length. Consequently, installation space volume and weight are saved, particularly where the first length is less than the second length. In some cases, the first length is less than or equal to half of the second length.

Steering column and steer-by-wire steering system

A method can be used to adjust a steering column for a motor vehicle that includes a casing unit in which a steering spindle is mounted rotatably about a longitudinal axis and at least two casing tubes that are guided so as to be adjustable relative to one another by adjustment travel in a longitudinal direction of the longitudinal axis. Along the adjustment travel, the casing tubes are extended farther out of one another in an operating region than in a transitional region, and a motorized adjustment drive acting on the casing tubes is actuated electrically for the relative adjustment of the casing tubes at a predetermined adjustment speed. To allow optimized switching between the operating region and the stowage position, a first adjustment speed is set in the operating region and a second adjustment speed, which is higher than the first adjustment speed, is set in the transitional region.

A steering column may include a casing unit in which a steering spindle is rotatably mounted about a longitudinal axis and which has at least three telescopically guided casing tubes that are mutually adjustable in an axial direction.
