Abstract
The invention relates to a steering-column assembly 1, in which the telescopic spindle 5.1 is fastened to the inner casing tube 2.1 via a crash element 4. The telescopic spindle 5.1 moves into the crash element 4 by virtue of the fact that the spindle nut 5.6 is fixed to the crash element 4, which permits reduced installation space for the telescopic spindle 5.1. In order to improve acoustic decoupling, the spindle nut 5.6 is composed at least partially of plastic. By mechanical decoupling of the tensile and compressive forces of the telescopic spindle 5.1 from the torque which acts on the telescopic spindle 5.1, the possibility is provided of using plastic for a drive shaft 5.4 of the telescopic spindle 5.1 and for the bearings 5.7, 5.7′ of the telescopic drive 5.3.
