Abstract
Official abstract text for this publication.
A control system for hybrid construction machine includes an engine, a main pump to be driven by the engine, a rotary shaft linking an assist pump, a regenerative hydraulic motor and a motor generator, and a clutch for linking the engine and the rotary shaft.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for hybrid construction machine, comprising: an engine; a main pump to be driven by the engine; a rotary shaft coupled to an assist pump, a regenerative hydraulic motor and a motor generator; and a clutch for linking the engine and the rotary shaft, wherein a hydraulic pressure from an actuator is regenerated in the regenerative hydraulic motor by disengaging the clutch and allowing a hydraulic pressure from the assist pump dri…
