Abstract
Disclosed is a device for superimposing rotational speeds in a vehicle steering system. Said device comprises an input shaft (1) and an output shaft (2) that are arranged in a longitudinal direction relative to each other, a support system (IIa, IIb) which is fixed to the vehicle body and in which the input shaft (1) and the output shaft (2) are rotatably positioned so as to be mounted at least in part, a servodrive (6, 7) encompassing a stator (7) that is located on the support system (IIa, IIb) and a rotor (6) that is mounted so as to be rotatable parallel to the axis of the input shaft. The input shaft (1) is connected to a first toothed disk (3) while the output shaft (2) is joined to a second toothed disk (4). At least one additional toothed wheel (5) is mounted on the rotor (6) at a distance from the axis of rotation of the rotor (6) so as to be rotatable about its own axis around the input shaft (1). The toothing of said additional toothed wheel (5) engages into both toothings of the first and second toothed disk (3, 4).
