Title:
CONTROL SYSTEM FOR HYBRID CONSTRUCTION MACHINERY
Document Type and Number:
WIPO Patent Application WO/2011/105279
Kind Code:
A1
Abstract:
The disclosed control system for hybrid construction machinery is provided with: a pair that is a first and a second main pump, which are variable displacement pumps; a first and a second pathway system that are connected to the first and the second main pumps and that have a plurality of control valves; main switching valves that are provided between the first and second pathway systems and the first and second main pumps; a hydraulic motor for electricity generation that is connected to the first and second main pumps with the main switching valves therebetween; a generator that is connected to the hydraulic motor for electricity generation; and a battery that stores power generated by the generator. When the main switching valve connected to at least one of the pathway systems is in a position that interconnects the main pump connected thereto with the hydraulic motor for electricity generation, the main switching valve connected to the other pathway system causes the other main pump to interconnect with the other pathway system.
