Abstract

본 발명은 휠 로더 등의 건설중장비의 트랜스 밋션 클러치 컷 오프 제어시스템 및 그 작동방법에 관한 것으로, 특히 차속이 일정속도 이하로 주행시에 브레이크를 밟으면 자동적으로 트랜스 밋션 클러치가 컷 오프되어 발생되는 동력손실 및 안전사고를 방지할 수 있는 클러치 컷 오프 제어시스템 및 그 작동방법에 관한 것으로, 브레이크 페달 조작에 의해 개폐 조정되는 압력스위치 및 차속센서로 구성된 입력부와, 상기 입력부로부터 입력신호를 받아 중앙처리장치에서 자체적으로 처리하여 출력신호를 보내는 처리부와, 상기 처리부로부터 명령신호를 받아서 클러치를 처리하여 출력신호를 보내는 처리부와, 상기 처리부로부터 명령신호를 받아서 클러치를 컷 오프 제어하는 구동부로 구성된 제어시스템 및 그 작동방법으로, 이와같이 구성된 본 발명을 실질적으로 중장비에 적용하여 제동장치의 제동기능을 향상시킬 뿐만아니라 제동시 차량에 대한 충격을 저하시켜 안전사고방지를 그 목적으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission clutch cut-off control system for a heavy construction equipment such as a wheel loader and a method of operating the same. Particularly, when the vehicle speed is below a certain speed, the transmission clutch automatically cuts off and the power loss is generated. And a clutch cut-off control system capable of preventing a safety accident and a method of operating the same, comprising: an input unit comprising a pressure switch and a vehicle speed sensor controlled to open and close by a brake pedal operation, and receiving an input signal from the input unit in a central processing unit. A control system comprising a processing unit which processes itself and sends an output signal, a processing unit which receives a command signal from the processing unit, processes the clutch and sends an output signal, and a drive unit which receives a command signal from the processing unit and controls the clutch to be cut off, and an operation thereof. In this way, the present foot Practical application in the heavy equipment is to prevent accidents as well as to improve the damping function of the damping device decreases the impact on the vehicle during braking for that purpose.
