Abstract

A steering column for a motor vehicle may comprise a steering column jacket with a jacket surface having a retaining segment. The retaining segment may at least partially surround a bearing for rotatably mounting a steering spindle about an axis of rotation. The retaining segment may have at least one tab that secures the bearing in the steering column jacket in a direction of the axis of rotation. The tab may be connected to the retaining segment of the steering column jacket along a bending edge. The bending edge may form a projection angle of at maximum 45° with a projected axis of rotation. The free end of the tab is bent around the bending edge towards the axis of rotation.

First claim

What is claimed is:

1. A steering column for a motor vehicle, the steering column comprising a steering column jacket with a jacket surface having a retaining segment, wherein the retaining segment at least partially surrounds a bearing for rotatably mounting a steering spindle about an axis of rotation, wherein the retaining segment includes a tab that secures the bearing in the steering column jacket in a direction of the axis of rotation, the tab being connected to the retaining segment of the steering column jacket along a bending edge and having a bevel disposed on a side of the tab that faces the bearing, wherein a projection angle between the bending edge and a projected axis of rotation is at most 45°, wherein a free end of the tab is bent around the bending edge toward the axis of rotation.

2. The steering column of claim 1 wherein the tab and the retaining segment are comprised of a formed sheet metal part.

3. The steering column of claim 1 wherein the bevel is configured to compensate for at least one of a predetermined tolerance in a width of the bearing or a tolerance in the tab.

4. The steering column of claim 1 wherein the bevel compensates for manufacturing variability in at least one of the bearing or the tab.

5. The steering column of claim 1 wherein the side of the tab facing the bearing forms an angle of inclination with the projected axis of rotation within a range of 45° to 85°.

6. The steering column of claim 1 wherein a shape of the tab is substantially triangular, wherein a base of the tab is formed by the bending edge, wherein a side of the tab facing the bearing is beveled, wherein a side of the tab facing away from the bearing is beveled or extends in a circumferential direction of the steering column jacket.

7. The steering column of claim 6 wherein the tab is flat.

8. The steering column of claim 1 wherein the tab is bent under force control around the bending edge to retain the bearing in the steering column jacket with a predetermined pretensioning force.

9. The steering column of claim 1 further comprising a bearing shoulder for positioning the bearing in the steering column jacket, wherein the tab is deformed such that the bearing is pretensioned against the bearing shoulder with a predetermined pretensioning force.

10. The steering column of claim 1 wherein the projected axis of rotation is parallel to the axis of rotation and is positioned radially outwards of the axis of rotation.

11. A steering column for a motor vehicle, the steering column comprising:
a bearing;
a steering column jacket with a jacket surface having a retaining segment, wherein the retaining segment at least partially surrounds the bearing for rotatably mounting a steering spindle about an axis of rotation; and
a tab that is disposed on the retaining segment and secures the bearing in the steering column jacket in a direction of the axis of rotation, the tab being connected to the retaining segment along a bending edge and having a bevel disposed on a side of the tab that faces the bearing, wherein a projection angle between the bending edge and a projected axis of rotation is at most 45°, wherein the tab is bendable inward from the bending edge.

12. The steering column of claim 11 wherein a side of the tab facing the bearing forms an angle of inclination with the projected axis of rotation within a range of 45° to 85°.

13. The steering column of claim 11 wherein a shape of the tab is substantially triangular.

14. The steering column of claim 11 wherein the tab is flat.

15. The steering column of claim 11 wherein the tab retains the bearing in the steering column jacket by applying a predetermined amount of force against the bearing.

16. The steering column of claim 11 wherein the tab is a first tab, the steering column further comprising a second tab that is disposed on the retaining segment and secures the bearing in the steering column jacket in the direction of the axis of rotation, the second tab being connected to the retaining segment along a second bending edge, wherein a projection angle between the second bending edge and a projected axis of rotation is at most 45°, wherein the second tab is bendable inward from the second bending edge.
