Abstract

A steering column for a motor vehicle has a rotatably mounted steering spindle and a motor-powered steering assistance device for steer angle superposition and/or torque assistance. The steering assistance device is connected to the steering spindle by at least one transmission element, and the steering spindle has at least two steering spindle parts connected to one another in torque-transmitting fashion. The steering spindle parts connected to one another in at the steering spindle between the transmission element and a steering wheel connection of the steering spindle, by at least one damping body for damping vibrations transmitted via the steering spindle. At least one of the steering spindle parts is rotatably mounted in a casing unit of the steering column. In the damping body, there is formed a cavity into which the casing unit can slide preferably in the event of a crash-induced deformation and/or displacement within the steering column.

Dependent claims

A steering column for a motor vehicle, said steering column comprising:

a rotatably supported steering spindle having a steering wheel mounting adapter;
and
a motor-driven steering assist device for steering angle superposition, torque support, or steering angle superposition and torque support;
wherein the steering assist device is connected with the steering spindle by a transmission element, and the steering spindle comprises at least two steering spindle parts connected with one another such that the at least two steering spindle parts transmit torque,
wherein the steering spindle parts, in a region of the steering spindle between the transmission element and the steering wheel mounting adapter of the steering spindle, are connected with one another by a damping body for damping vibrations transferred via the steering spindle,
wherein at least one of the at least two steering spindle parts is rotatably supported in a jacket unit of the steering column, and in the damping body, a hollow volume is formed into which the jacket unit is slidable.
