The invention relates to the technical field of vehicle control, in particular to a closed pump driving system and an engineering vehicle. The closed pump driving system comprises an inner closed pump, an outer closed pump, an inner motor and an outer motor, the inner closed pump comprises an inner closed pump first oil port and an inner closed pump second oil port, the outer closed pump comprises an outer closed pump first oil port and an outer closed pump second oil port, and the inner motor and the outer motor are both used for driving an inner wheel and an outer wheel to rotate. The inner motor comprises an inner motor first oil port and an inner motor second oil port, the outer motor comprises an outer motor first oil port and an outer motor second oil port, and the inner closed pump is used for being communicated with the outer closed pump. When a vehicle normally runs and steers, the output flow of the inner closed pump and the output flow of the outer closed pump can be self-adaptive to the required flow of the inner motor and the required flow of the outer motor, the control effect of the closed pump driving system on the inner motor and the outer motor is improved, and the steering difficulty of the vehicle is reduced.

    本发明涉及车辆控制技术领域,具体而言,涉及一种闭式泵驱动系统及工程车。其中,一种闭式泵驱动系统,包括内闭式泵、外闭式泵、内马达、外马达,内闭式泵包括内闭式泵第一油口、内闭式泵第二油口,外闭式泵包括外闭式泵第一油口、外闭式泵第二油口,内马达和外马达均用于带动内车轮、外车轮转动,内马达包括内马达第一油口、内马达第二油口,外马达包括外马达第一油口、外马达第二油口,内闭式泵用于与外闭式泵连通。在车辆正常行驶和转向时,内闭式泵、外闭式泵的输出流量与内马达、外马达的所需流量可以实现自适应,提升了闭式泵驱动系统对内马达、外马达的控制作用,降低了车辆转向的难度。
