ABSTRACT:
A hydraulic steering assistor, which can be switched off, for a vehicle with a hydraulic pump, an electric motor and a relay, which vehicle is driven by an electromotor, runs on wheels and is actuated by means of a drive control. By means of a switch disposed in the drive control, the motor of the hydraulic pump for the steering assistor is turned on through a time relay (having an activatable delay time) and another relay, and during the rotation of the armature shaft of the electromotor of the vehicle the time relay receives pulses from a pulse generator in the electromotor preventing the activation (initiation) and thus expiration of the delay time, and the pump driving motor for the steering assistor is stopped only after the absence of the pulses while in the neutral position, causing activation of the time relay and then after expiration of the delay time, by means of the drive control and opened switch.
