Abstract

본 발명은 굴삭기나 크레인등과 같은 주행가능한 각종 건설기계의 주행 중 작업장치를 조작하더라도 주행의 직진성을 계속 유지할 수 있도록 하는 장치에 관한 것이다. 특히 본 발명은, 위와 같은 직진주행장치에서 작업장치계 엑츄에이터에 공급되는 유량의 일부를 분기하여 주행계에 보충공급함에 따라 직진주행장치 작동시 주행속도의 급감이 방지되도록 한 중장비의 직진주행장치에 관한 것이다. 본 발명에 의한 직진주행장치는, 주행직진 밸브를 경유한 직후의 주행계 유로의 소정위치와 작업장치계 유로의 소정위치를 상호 연결하는 연결유로와, 상기 연결유로 중에 설치되는 오리피스와, 상기 연결유로 중에 설치되며 상기 작업장치계 유로로부터 상기 주행계 유로로의 오일 흐름만을 허용하는 체크밸브를 구비하여 구성된다.The present invention relates to a device for maintaining the straightness of the running even when operating the work device during the running of a variety of runable construction machines such as excavators and cranes. In particular, the present invention, in the straight running device as described above by branching a part of the flow rate supplied to the work system actuator supplementary supply to the traveling system in the straight traveling device of heavy equipment to prevent a sudden drop in the running speed when the straight traveling device is operated. It is about. According to an aspect of the present invention, there is provided a straight traveling device comprising: a connection channel for interconnecting a predetermined position of a traveling system flow path immediately after passing through a traveling straight valve with a predetermined position of a working system flow path; an orifice provided in the connection flow path; It is provided in the flow path and is provided with the check valve which only permits the flow of oil from the said work system flow path to the said traveling system flow path.
