Abstract
An electromechanical dual steering system for a utility vehicle includes two steering systems, each having a drive unit for actuating one steering linkage each for wheels of the utility vehicle. Each drive unit has an electric motor. The dual steering system has a main power supply for supplying the electric motors with energy. The electromechanical dual steering system is characterized in that the dual steering system has at least one emergency power supply for supplying at least one electric motor with energy in the event that the main power supply fails.
Claims19
An electromechanical dual-circuit steering system for a utility vehicle, comprising:
- two steering systems, each comprising a drive unit for actuating a respective steering linkage for wheels of the utility vehicle, wherein each drive unit has a respective electric motor;
- a main power supply of the dual-circuit steering system for supplying the electric motors with energy;
- and
- at least one emergency power supply for supplying at least one of the electric motors with energy in an event of a failure of the main power supply, wherein
- the dual-circuit steering system comprises one substantially independent emergency power supply per electric motor.
