The invention relates to the technical field of hydraulic systems, and provides a hydraulic control system, an operation machine and a power output control method. In the hydraulic control system, a pressure regulating valve group is connected with an oil source so as to regulate the output pressure of the oil source. And the auxiliary power execution unit is connected with the rear drive axle. The auxiliary power control valve group is connected between the oil source and the auxiliary power execution unit. The transmission speed ratio detection device is used for detecting the transmission speed ratio. The control device adjusts the working state of the auxiliary power control valve set and the set pressure of the pressure adjusting valve set based on the detection result of the transmission speed ratio detection device. The control device not only can control the starting state of the auxiliary power execution unit through the auxiliary power control valve set, but also can flexibly adjust the set pressure of the pressure adjusting valve set based on the transmission speed ratio, and then the output pressure of the oil source is controlled. Therefore, not only can the actual working efficiency of the hydraulic control system be improved, but also energy waste caused in the working process of the hydraulic control system can be reduced.
本发明涉及液压系统技术领域,提供了一种液压控制系统、作业机械及动力输出控制方法。在液压控制系统中,压力调节阀组与油源连接,以调节油源的输出压力。辅助动力执行单元与后驱动桥连接。辅助动力控制阀组连接于油源与辅助动力执行单元之间。传动速比检测装置用于检测传动速比。控制装置基于传动速比检测装置的检测结果调节辅助动力控制阀组的工作状态以及压力调节阀组的设定压力。控制装置不仅能通过辅助动力控制阀组控制辅助动力执行单元的启动状态,还能基于传动速比灵活调节压力调节阀组的设定压力,进而控制油源的输出压力。由此,不仅能提升液压控制系统的实际工作效率,还能够减少其在工作过程中所造成的能源浪费。
