Abstract

하이브리드 굴삭기 붐 구동시스템 및 그 제어방법이 개시된다. 개시된 발명은 모터 또는 발전기로 작동되는 전동기(110),상기 전동기(110)에서 생산된 전기를 저장하는 축전장치(115), 상기 전동기(110)로 구동되어 붐(100)에 작동유를 공급하는 유압펌프모터(120), 상기 유압펌프모터(120)의 토출라인(121)과 유입라인(122)을 붐(100)의 헤드(106) 또는 로드(107) 측과 선택적으로 연결하거나 차단하는 폐회로를 구성하는 붐 제어밸브(125), 상기 전동기(110)와 별도로 마련된 구동원(141)에 의해 구동되며 버켓, 주행모터 또는 암에 작동유를 공급하는 메인펌프(140), 상기 메인펌프(140)의 토출라인을 상기 유압펌프모터(120)의 토출라인(121)에 연결시켜, 상기 메인펌프(140) 및 상기 유압펌프모터(120) 각각으로 부터 토출되는 작동유를 합류 가능하게 하는 붐 보조밸브(144) 및 상기 전동기(110), 상기 유압펌프모터(120), 상기 붐 제어밸브(125)를 제어하는 제어부(160)를 포함한다. 이와 같은 본 발명은 전동기를 이용하면서도 굴삭기의 주된 사용 용도인 굴삭 작업 시 에너지 손실을 최소화하고, 붐의 작동성능을 확보하며, 봄의 회생 가능한 에너지를 회수할 수 있다.
