Abstract
본 발명은 중장비용 선회모터 유압시스템에 관한 것으로, 특히 굴삭기나 크레인등과 같이 하부프레임에 대해 상부프레임이 선회가능하게 결합된 각종 중장비의 선회모터를 위한 유압시스템에 관한 것이다. 본 발명은, 중장비의 선회모터 유압시스템에 있어서, 유압펌프와, 상기 유압펌프에 의해 작동되며 사판 경전각 변화에 의해 용량이 가변조절되는 가변용량형 선회모터와, 상기 유압펌프로부터 상기 선회모터로의 유로를 절환접속함에 의해 상기 선회모터를 구동 및 정지시키고 상기 선회모터의 회전방향을 제어하는 콘트롤밸브와, 운전자로부터 소정의 조작신호를 입력받기 위한 조작수단과, 상기 조작수단에 입력된 상기 조작신호에 따라 상기 선회모터의 상기 사판 경전각을 조절하여 상기 선회모터의 용량을 가변조절하는 사판 경전각 조정수단을 구비하여 구성된다(제2도).BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic system for a swing motor for heavy equipment, and more particularly to a hydraulic system for a swing motor of a variety of heavy equipment in which an upper frame is pivotably coupled to a lower frame such as an excavator or a crane. The present invention relates to a hydraulic system of a heavy-duty swing motor, a hydraulic pump, a variable displacement swing motor operated by the hydraulic pump and variable in capacity by a swash plate tilt angle change, and from the hydraulic pump to the swing motor. A control valve for driving and stopping the swing motor by controlling the flow path of the flow path and controlling the rotation direction of the swing motor, operation means for receiving a predetermined operation signal from a driver, and the operation input to the operation means. And swash plate tilt angle adjusting means for controlling the capacity of the swing motor by adjusting the swash plate tilt angle of the swing motor according to a signal (FIG. 2).
