Abstract
A steering device for steering the wheels of a steering axle of a motor vehicle having at least three axles. The steering axle is designed as a trailing or leading axle, with a hydraulic arrangement which has an actuating assembly for the steering actuation of the wheels, and a regulating/control valve for pressure to act upon hydraulic connections of the actuating assembly and a clearing valve, by means of which the steering device can be changed over between normal operation and emergency operation. In the emergency operation, the hydraulic connections of the actuating assembly are connected to one another. Four throttle elements are provided. The first is arranged upstream and the second downstream of a connection point of the clearing valve to a first hydraulic line connecting the regulating/ control valve and actuating assembly. The third is arranged upstream and the fourth downstream of a connection point of the clearing valve to a second hydraulic line connecting the regulating/control valve and actuating assembly.
