摘要： The invention relates to steering columns for motor vehicles, having a steering shaft (1) which comprises two interlocking steering shaft parts (2, 3) that can be moved relative to each other. In steer-by-wire steering devices, a sensor detects and feeds the rotational angle position of the steering wheel to an evaluation unit, which activates an actuator (9). The actuator shaft is connected to the steering shaft in a rotationally fixed manner. The production is elaborate and difficult because in particular the axes of the actuator shaft and the steering shaft must be exactly aligned. In order to simplify assembly and production, one of the two steering shaft parts (2, 3) forms the actuator shaft, thus making it very easy to assemble the actuator shaft and the steering shaft (1) with axial precision. The steering column is used in steer-by-wire steering devices in motor vehicles.
