Abstract
The invention relates to a motor vehicle steering system comprising a differential drive, said differential drive having a carrier structure (12, 33), a drive shaft (3) with a shaft end (3a) facing the differential drive, an output unit (2) with a shaft end (2a) facing the differential drive, and an auxiliary drive comprising a stator (4) and a rotor (6). The aim of the invention is to simplify the structure of one such differential drive as much as possible. To this end, the shaft end (3a) of the drive shaft (3) carries a first toothed disk (7) which is connected to the drive shaft (3) in a rotationally fixed manner, the shaft end (2a) of the output unit (2) is connected to at least parts of the carrier structure (12, 33) in a rotationally fixed manner; the carrier structure (12, 33) carries a second toothed disk (8) which is connected thereto in a rotationally fixed manner; and the rotor (6) comprises a first cylindrical section (6a) and a second cylindrical section (6b) that is bent in relation to the first section (6a) at an angle (a). The first section (6a) faces the output unit (2) and the second section (6b) faces the drive shaft (3). A swash unit (9a, 9b) arranged on the be…
