Superposition device for steering system of motor vehicle, has output shaft, which is implemented as hollow shaft and encloses axial section of drive shaft

摘要

The superposition device (6a), has a controllable servo unit (8) and an output shaft (17), which is implemented as a hollow shaft and encloses an axial section (35) of the drive shaft (9). The superposition gear (7a) is implemented as a planetary gear. An independent claim is also included for the steering system with superposition device.
