Superimposed steering system for vehicle i.e. passenger car, has form-fitting resilient clutch integrated in one gear input shaft and/or gear output shaft, and variable ratio gear unit and/or servomotor fixed at body of car

摘要

The system (1) has a variable ratio gear unit (4) with gear input shafts (2, 3) for superimposing a rotation angle occurring at the shafts on a gear output shaft (5) of the gear unit. The input shafts are effectively connected with a steering handle (6) and a servomotor (7) e.g. electrical hollow shaft motor, respectively. The shafts (2, 5) form a steering shaft (8) for connecting the handle with a steering gear. A form-fitting resilient clutch (9) is integrated in the shaft (2) and/or the shaft (5), where the gear unit and/or the servomotor are fixed at a body of a vehicle.
