The present invention relates to a hydraulic power driving system for a cargo vehicle, and more particularly, to a hydraulic power driving system for a cargo vehicle, in which, when a power unit necessary for work is driven by using engine power of a cargo vehicle equipped with a loading box, the power unit is driven by circulation oil circulating through a direct hydraulic pump connected to a power take off (PTO) device, an oil tank, a hydraulic motor, and an operating valve, so that various power units are used according to a type of work. The system according to the present invention includes: a power take-off device installed to be connected to a transmission of a cargo vehicle, the cabin including a cabin to be indoors and a loading box to be positioned behind the cabin; a direct hydraulic pump mounted on one side of the power take-off unit and configured to have a pair of branching members for projecting to the outside; an oil tank connected to the direct hydraulic pump through a flow pipe in a state of being mounted on a lower side of the cargo vehicle and containing circulating oil therein; a hydraulic motor connected to the power unit required for the operation in a state of being loaded on the loading box; and a working valve for circulating the circulating oil contained in the oil tank by operation of an operator so that the hydraulic motor can be driven, in which the direct hydraulic pump and the hydraulic motor are connected to each other via the flow pipe in a state where they are mounted on the loading box. Accordingly, the engine power of the cargo vehicle is used for driving the power unit.

    본 발명은 화물차량용 유압식 동력구동시스템에 관한 것으로, 보다 상세하게는 적재함이 구비된 화물차량의 엔진 동력을 이용하여 작업에 필요한 동력장치를 구동하는 경우, 동력인출장치(PTO: Power Take Off)에 연결된 직결유압펌프, 오일탱크, 유압모터, 작동밸브를 순환하는 순환오일에 의해 상기 동력장치를 구동함으로써 작업종류에 따른 다양한 동력장치를 사용할 수 있도록 하는 화물차량용 유압식 동력구동시스템에 관한 것이다. 본 발명은 실내가 조성되는 캐빈과, 상기 캐빈의 후방에 위치되도록 설치되는 적재함을 포함하여 이루어진 화물차량의 트랜스미션에 연결되게 설치되는 동력인출장치; 상기 동력인출장치의 일측에 장착되되 유로관의 연결을 위한 한 쌍의 분기구가 외부로 돌출되게 형성된 직결유압펌프; 상기 화물차량의 하측에 장착된 상태로 상기 직결유압펌프에 유로관을 매개로 연결되어 내부에 순환오일이 수용된 오일탱크; 상기 적재함에 적재된 상태로 작업에 필요한 동력장치가 연결되는 유압모터;상기 적재함에 장착된 상태로 상기 직결유압펌프 및 유압모터가 유로관을 매개로 연결되어 작업자의 조작에 의해 상기 오일탱크에 수용된 순환오일이 순환되면서 상기 유압모터가 구동될 수 있도록 하는 작동밸브;로 구성되어 화물차량의 엔진 동력을 상기 동력장치의 구동에 이용할 수 있도록 하는 것을 특징으로 한다.
