View Patent ↗A clamping device for the positional fixing of a vehicle steering column which can be adjusted in its length and/or inclination has a clamping disc and a plurality of rolling bodies, with clamping ramps for the rolling bodies being formed on the surface of the clamping disc, wherein the rolling bodies each make contact with one of a plurality of separate contact elements arranged in a common plane.
1. A clamping device for the positional fixing of a vehicle steering column which can be adjusted in its length and/or inclination, comprising a single clamping disc and a plurality of rolling bodies, with clamping ramps for the rolling bodies being formed on a surface of the clamping disc, wherein a side of each of the rolling bodies that faces in a direction opposite to the single clamping disc makes contact with a respective one of a plurality of separate, axially movable contact elements arranged in a common plane.
2. A clamping device of claim 1 , wherein the contact elements are mounted in a common guide element.
3. A clamping device of claim 2 , wherein the guide element is manufactured from plastic.
4. A clamping device of claim 2 , wherein the guide element provided for the mounting of the contact elements serves at the same time to guide the rolling bodies.
5. A clamping device of claim 2 , wherein the guide element has an adjustment contour for a linear adjustment.
6. A clamping device of claim 2 , wherein the guide element has a latching element for the latching in place of a lever provided for pivoting the clamping disc.
7. A clamping device of claim 1 , wherein the contact elements have a cylindrical basic shape.
8. A clamping device of claim 1 , wherein the contact elements are manufactured of metal.
9. A clamping device of claim 1 , wherein the contact elements have greater elastic flexibility than the rolling bodies.
