Abstract
A steering column for a steer-by-wire steering system may include a casing unit in which a steering spindle is received such that the steering spindle is rotatable about a longitudinal axis. The casing unit may have an inner casing tube, which is rotatable and longitudinally displaceable, received coaxially in an outer casing tube. The steering spindle may have a longitudinally displaceable inner shaft that is received coaxially in an outer shaft in a torque-transmitting manner. The steering spindle may be coupled to a drive unit of a feedback actuator that has an electric motor for the generation and introduction of a feedback torque into the steering spindle. The drive unit has a recess that is arranged coaxially with respect to the longitudinal axis, is open toward the outer shaft, and has a maximum inscribed internal diameter that is greater than an external diameter of the outer shaft.
