Claims (3)
- 엔진과, 이 엔진에 의해 구동되는 유압펌프와, 상기 유압펌프로부터의 토출유(吐出油)에 의해 작동되는 유압 액추에이터와, 엔진과 조합되는 전동기와, 엔진에 의해 구동되는 발전기와, 상기 발전기에 의한 발전전력을 충전하는 배터리를 갖춘 다기능식 건설기계에 있어서,조작레버 또는 조작패널에 파워업(power up)용 스위치가 설치됨과 아울러 상기 파워업용 스위치로부터의 신호가 입력되는 컨트롤러가 설치되며, 상기 컨트롤러는, 상기 파워업용 스위치로부터의 신호입력에 의해, 상기 유압펌프의 구동을 도와주는 토크를 출력하도록 상기 전동기의 출력토크를 제어하는 것을 특징으로 하는 다기능식 건설기계.
- 제 1항에 있어서, 상기 파워업용 스위치의 조작시에, 상기 컨트롤러는, 상기 유압펌프의 흡수토크와 엔진의 정격출력점 토크를 비교하여, 그 흡수토크가 그 정격출력점 토크보다도 낮다고 판단한 경우에, 엔진의 회전수를 일정하게 제어함과 아울러, 그 정격출력점 토크근방까지 가도록 도와주는 토크를 출력하도록 상기 전동기의 출력토크를 제어하는 다기능식 건설기계.
- 제 1 항 또는 제 2항에 있어서, 상기 파워업용 스위치의 조작시에, 상기 컨트롤러는, 상기 유압펌프의 흡수토크와 엔진의 정격출력점 토크를 비교하여, 그 흡수토크가 그 정격출력점 토크를 포함한 그 근방이라고 판단한 경우에, 엔진의 회전수를 일정하게 제어함과 아울러, 그 정격출력점 토크를 초과하여 가게 도와주는 토크를 출력하도록 상기 전동기의 출력토크를 제어하는 다기능식 건설기계.
