Abstract
A soil processing machine, in particular a soil compactor, includes a hydraulic steering system with at least one steering element actuated with pressurized fluid and an electrohydraulic pressurized fluid source with at least one steering pressurized fluid pump that can be driven by at least one electric motor for feeding pressurized fluid into a steering pressurized fluid circuit.
Claims16
A soil processing machine comprising:
- a hydraulic steering system with at least one steering element actuated with pressurized fluid and an electrohydraulic steering pressurized fluid source with at least one hydraulic steering pump driven by at least one electric motor for feeding pressurized fluid into a hydraulic steering circuit;
- and
- a hydraulic drive system, wherein the hydraulic drive system includes an electrohydraulic pressurized fluid source with at least one electric motor and at least one hydraulic drive pump for supplying pressurized fluid to a hydraulic drive circuit and at least one hydraulic drive motor supplied with pressurized fluid from the hydraulic drive circuit,
- wherein at least one electric motor of the at least one electric motor of the electrohydraulic steering pressurized fluid source of the hydraulic steering system and at least one electric motor of the at least one electric motor of the electrohydraulic pressurized fluid source of the hydraulic drive system are selectively operated independently of one another.
