Abstract

A steering column may comprise a casing tube and a steering spindle that is mounted in the casing tube so as to be rotatable about a longitudinal axis. The steering column may further comprise fastening elements for fastening the steering column on the vehicle body. The steering column may include a pivot bearing for height adjustment of the steering column. The pivot bearing may be provided on a region of the steering column that is remote from the steering wheel. Further, the pivot bearing may be disposed or formed in a supporting element that is fastened non-releasably on the casing tube.

Claims

1. A steering column for a motor vehicle comprising:

a casing tube;

a steering spindle that is mounted in the casing tube so as to be rotatable about a longitudinal axis;

a supporting element that is configured as a separate component and is fastened non-releasably on the casing tube; and

a pivot bearing configured to enable height adjustment of the steering column, the pivot bearing defining a pivot axis about which the casing tube pivots to adjust the height of the steering spindle, the pivot bearing being disposed on a region of the steering column that is remote from a driver-side end of the steering spindle, wherein the pivot bearing is either disposed or formed in the supporting element;

wherein the casing tube comprises a fastening structure that extends in a direction of the longitudinal axis, wherein the supporting element is fastenable to the fastening structure, and

wherein the fastening structure comprises longitudinal grooves that face away from each other, wherein the supporting element engages in the longitudinal grooves.

2. The steering column of claim 1 wherein the supporting element is caulked, pressed, welded, or adhesively bonded to the casing tube.

3. The steering column of claim 1 wherein the supporting element engages around an outer portion of the casing tube positioned between the longitudinal grooves.

4. The steering column of claim 1 wherein the supporting element comprises side walls that in a mounted state extend away from the longitudinal grooves and are oriented with flat sides parallel to the longitudinal axis.

5. The steering column of claim 4 wherein each of the side walls of the supporting element include an elongate recess, wherein a longitudinal extent of each elongate recess is oriented parallel to the longitudinal axis.

6. The steering column of claim 5 further comprising a tubular bushing disposed in the elongate recesses transversely with respect to the longitudinal axis, wherein the tubular bushing defines the pivot axis and is configured as a fastening element for fastening the steering column to the motor vehicle and in the mounted state serves as a bearing axis for vertically pivoting the steering column during operation.

7. The steering column of claim 6 wherein the supporting element comprises a guide groove disposed between the side walls, wherein a sliding member is guided with friction in the guide groove, wherein the sliding member projects into a region between the elongate recesses such that the tubular bushing carries along the sliding member during a movement in a direction of the longitudinal axis within the elongate recesses.

8. The steering column of claim 1 wherein the supporting element comprises a guide groove disposed between the side walls, wherein a sliding member is guided with friction in the guide groove.

9. The steering column of claim 8 wherein the guide groove is a T-groove, wherein the sliding member is a sliding block.

10. The steering column of claim 8 wherein the sliding member is fastenable in the guide groove with a fastening means.

11. The steering column of claim 1 further comprising fastening elements for fastening the steering column on the vehicle body.
