The invention relates to the field of vehicles, in particular to a hydraulic walking system and an engineering vehicle. The hydraulic walking system comprises a power assembly, a first motor set, a second motor set, a speed control valve set and a switching valve set, according to the hydraulic walking system and the engineering vehicle, the rotating speed of the first motor set is adjusted through the speed control valve set, so that the first motor set walks at different rotating speeds in the two-drive state, and the working efficiency is improved. And the switching valve group is used for communicating the walking pump with the second motor group, so that the engineering vehicle can climb and walk in a four-wheel drive mode, and the speed control valve group and the switching valve group are matched with each other, so that the engineering vehicle can walk in the four-wheel drive mode, a two-wheel drive low-speed mode and a two-wheel drive high-speed mode, the walking requirements under different working conditions are met, and the working efficiency of the engineering vehicle is improved. The working efficiency of the engineering vehicle is improved.
本发明涉及车辆领域,尤其涉及一种液压行走系统及工程车辆。液压行走系统包括动力组件、第一马达组、第二马达组、速度控制阀组和切换阀组,本发明提供的液压行走系统及工程车辆,通过速度控制阀组调节第一马达组的转速,以使第一马达组在两驱状态下实现不同转速的行走,切换阀组则用于将行走泵与第二马达组连通,从而实现工程车辆在四驱模式下爬坡行走,通过速度控制阀组与切换阀组二者相互配合,以实现工程车辆在四驱模式、两驱低速模式和两驱高速模式下行走,进而满足不同工况下的行走需求,提高工程车辆的工作效率。
