Abstract

An auxiliary steering device for a hydrostatic vehicle steering system, includes an input shaft, which can be actuated or set in rotation by a steering wheel, an output shaft for actuating a steering metering valve, and a planetary gearing. The planetary gearing includes a planetary wheel carrier with multiple planetary wheels, which mesh with a sun gear and a surrounding ring gear. The input shaft is connected to the planetary wheel carrier and the output shaft is connected to the sun gear in each case for conjoint rotation. The auxiliary steering device has an electric drive for exerting a torque on the ring gear, a braking device for fixing the input shaft, and a coupling device for producing a rotationally fixed connection between the output shaft and the planetary wheel carrier.
