Abstract
Description
Claims (4)
- 엔진의 목표 회전수를 설정하기 위해 전기적 신호를 출력하는 엔진회전수 설정수단(11)과, 상기 엔진회전수 설정수단(11)에서 제공되는 전기적 신호를 수신하여 엔진회전수 제어신호를 출력하는 스로틀 컨트롤러(12)와, 상기 스로틀 컨트롤러(12)에서 제공되는 제어신호에 의해 구동되어 스로틀레버(13)의 각도를 조절하는 스로틀레버 제어모터(14)와, 상기 스로틀레버 제어모터(14)의 작동에 의해 각도가 조절되어 엔진으로 공급되는 연료량을 조절하는 스로틀레버(13)를 포함한 굴삭기의 엔진제어장치에 있어서,상기 스로틀 컨트롤러(12)에 엔진회전수를 증감시키는 전기적 신호를 제공하도록 작업장치를 조작하는 작업레버(20)에 설치된 엔진회전수 가속제어수단(21)을 더 포함하고,상기 엔진회전수 가속제어수단(21)은 운전자가 조작하면, 미리 설정된 엔진회전수만큼 엔진회전수를 증가시키거나 감소시키는 출력신호를 스로틀 컨트롤러(12)로 인가하는 것을 특징으로 하는 굴삭기의 엔진제어장치.
- 삭제
- 제1항에 있어서, 상기 엔진회전수 가속제어수단(21)은 조작변위량에 비례하 여 출력신호값을 제공하는 가변스위치로 구성된 것을 특징으로 하는 굴삭기의 엔진제어장치.
- 제1항에 있어서, 상기 엔진회전수 가속제어수단(21)은 온ㆍ오프스위치로 구성되고, 온신호에 의해 미리 설정된 엔진회전수만큼 증가시키도록 출력신호를 제공하는 것을 특징으로 하는 굴삭기의 엔진제어장치.
