1. A clamping apparatus for a steering column, the clamping apparatus comprising:
a stroke-generating disk that is rotatable about a clamping axis and is connected to a pressure disk via a first stroke-generating gearing and a second stroke-generating gearing, with the pressure disk being stationary relative to rotation of the stroke-generating disk,
wherein the first stroke-generating gearing is configured to convert a relative rotation of the stroke-generating disk in a first actuating angle range in a clamping direction into a first axial stroke relative to the pressure disk,
wherein the second stroke-generating gearing is configured to convert further rotation of the stroke-generating disk following the first actuating angle range in a second actuating angle range into a second axial stroke between the stroke-generating disk and the pressure disk,
wherein at least one of the first or second stroke-generating gearings is a tilting pin gearing with a tilting pin that is supported in a direction of a pin axis between corresponding bearing points on the stroke-generating disk and the pressure disk.
