Steering column comprising a steering bearing, and a steering bearing of a steering column

A steering column comprising:

• at least one steering column tube;
• a steering spindle;
• and
• at least one steering bearing for a rotatable mounting of the steering spindle in the steering column tube, the steering bearing including at least an outer ring seated in the steering column tube, an inner ring, and rolling elements arranged between the outer ring and a raceway section of the inner ring, the inner ring bearing only at a first and a second point against the steering spindle and including a first section axially adjoining the raceway section and bearing under pre-stress against the first point on the steering spindle, and further comprising a second section axially spaced apart from the first section and axially adjoining the raceway section and including a first end of the inner ring interacting with the steering spindle at the second point, a third section made in one piece with the first section axially adjoining the first section without contact with the steering spindle in a radial direction so that the first section extends axially between the raceway section and the third section and that the third section merges into a second end of the inner ring, the second end of the inner ring without contact with the steering spindle,
• wherein the inner ring includes at least one edge on the first end, the edge interacting at the second point with a surface of the steering spindle, and
• wherein the at least one edge includes at least two edges interacting at the second point with the surface of the steering spindle, each one of the edges being configured on a respective tooth-shaped tab configured in one piece with the inner ring and that the at least two tabs are separated from each other in a peripheral direction through recesses configured on the first end.

A steering bearing for a steering column having at least one steering column tube and a steering spindle, the steering bearing for a rotatable mounting of the steering spindle in the steering column tube and comprising:

• at least an outer ring seated in the steering column tube, an inner ring, and rolling elements arranged between the outer ring and a raceway section of the inner ring, the inner ring bearing only at a first and a second point against the steering spindle and including a first section axially adjoining the raceway section and bearing under pre-stress against the first point on the steering spindle, and further comprising a second section axially spaced apart from the first section and axially adjoining the raceway section and including a first end of the inner ring interacting with the steering spindle at the second point, a third section made in one piece with the first section axially adjoining the first section without contact with the steering spindle in a radial direction so that the first section extends axially between the raceway section and the third section and that the third section merges into a second end of the inner ring, the second end of the inner ring without contact with the steering spindle, a smallest radial inner dimension of the third section being larger than a largest radial inner dimension of the first section;
• wherein radial outer dimensions of the first section are larger than those of the third section at least at a point where the third section axially adjoins the first section.
