Abstract
A steering shaft component (10) comprises a first and a second steering shaft section (12, 14) and at least a first bending section (28x) extending between the first and the second steering shaft sections (12, 14). The first bending section (28x) is formed integrally with at least one of the steering shaft sections (12, 14), but has a different cross section from this steering shaft section (12, 14). Furthermore, a mechanical stop for limiting the maximum angle of rotation of the two steering shaft sections relative to each other is provided.

-40. (canceled)
A steering shaft component, comprising
- a first and a second steering shaft section comprising a common longitudinal axis,
- at least two bending sections separate from one another, wherein each of the bending sections substantially extends in the axial direction between the first and the second steering shaft sections and is disposed spaced from the common longitudinal axis, and
- at least two cut-outs, wherein each bending section is laterally adjacent to at least one of these cut-outs, respectively,
- wherein at least one of the cut-outs defines at least one stop area of one of the steering shaft sections which is configured to limit as a mechanical stop the maximum angle of rotation of the two steering shaft sections relative to each other.
The steering shaft component according to claim 40, wherein the stop area is configured to come into contact with at least one bending section and/or the other steering shaft section in order to limit the maximum angle of rotation of the two steering shaft sections relative to each other.
The steering shaft component according to claim 40, wherein the at least one stop area is disposed, in the circumferential direction, next to at least one of the bending sections and/or next to at least one tab which is adjacent to one of the bending sections in the axial direction.
The steering shaft component according to claim 40, wherein each of the bending sections is subjected more to bending than to torsion during a rotation of the first steering shaft section relative to the second steering shaft section.
A steering shaft component, comprising
- a first and a second steering shaft section,
- at least one first bending section extending between the first and the second steering shaft sections, wherein the first bending section is formed integrally with at least one of the steering shaft sections but has a different cross section from this steering shaft section, and
- at least one mechanical stop for limiting the maximum angle of rotation of the two steering shaft sections relative to each other.
The steering shaft component according to claim 40, wherein the first and the second steering shaft sections are configured in a tubular shape.
The steering shaft component according to claim 40, wherein each bending section is formed integrally with at least one of the steering shaft sections, respectively.
The steering shaft component according to claim 40, wherein at least one bending section is formed integrally with the two steering shaft sections.
The steering shaft component according to claim 40, wherein each bending section is laterally limited by at least one cut-out in the steering shaft component, respectively.
A steering shaft component, comprising
- a tubular first steering shaft section, and
- a tubular second steering shaft section, wherein
- the first and the second steering shaft sections are formed integrally with one another and have at least one cut-out that defines at least one bending section of the steering shaft component,
- the steering shaft component further comprising at least one mechanical stop for limiting the maximum angle of rotation of the two steering shaft sections relative to each other.
The steering shaft component according to claim 40, wherein each bending section has a maximum width of at most 8 mm or at most 5 mm or at most 3 mm.
The steering shaft component according to claim 40, wherein each bending section has a length that is at least 5 times or at least 10 times of the maximum width of the bending section.
The steering shaft component according to claim 40, wherein at least one stop area of one of the steering shaft sections is configured to come into contact with at least one bending section and/or the other steering shaft section in order to limit the maximum angle of rotation of the two steering shaft sections relative to each other.
The steering shaft component according to claim 40, wherein the first and the second steering shaft sections are disposed axially one behind the other.
The steering shaft component according to claim 40, wherein a pull-out protection is provided which prevents the steering shaft sections from being pulled apart in the axial direction.
The steering shaft component according to claim 40, wherein the two steering shaft sections have approximately the same external circumference at least in the area of the bending section or bending sections.
The steering shaft component according to claim 40, further comprising an influencing device that reacts to a rotation of the first steering shaft section relative to the second steering shaft section.
The steering shaft component according to claim 40, further comprising at least one further component which comprises at least one web that reaches into one of the cut-outs between the bending sections and adjacent stop areas.
A method for producing a steering shaft component, the steering shaft component comprising a first and a second steering shaft section and at least one bending section substantially extending between the first and the second steering shaft sections, the method comprising stamping at least one cut-out into a flat metal workpiece, rounding the stamped workpiece to form a tube, and welding the tube to form at least the first and second steering shaft sections and the bending section.
