许多农用运输车上设有专门的自卸系统,其功用是使货厢自动倾斜一个角度,将厢内的货物倾卸出来,以减轻人工卸车的劳动强度。自卸系统的工作是由专设的液压系统实现的。液压系统主要由油泵、分配器、油缸和油箱等组成。工作时液压油泵由变速箱的动力输出轴或其他装置驱动,从油箱泵出液压油,并将压力油经过分配器压入油缸的工作腔,使车厢抬起,实现自动倾卸,货物倾卸完毕,操纵分配器停止向油缸供油,同时使油缸与油箱相通,车厢在自重作用下实现复位。农用运输车的液压自卸系统多采用齿轮油泵。齿轮泵结构简单,体积小,
Many agricultural transport vehicles are equipped with a special dump system, whose function is to automatically tilt the cargo box at an angle to dump the contents of the cabin so as to reduce the labor intensity of manual unloading. The work of the dump system is achieved by a dedicated hydraulic system. Hydraulic system consists of pumps, distributors, fuel tanks and fuel tanks and other components. When working, the hydraulic pump is driven by the power output shaft or other device of the transmission, pumps the hydraulic oil from the fuel tank, and presses the pressure oil into the working chamber of the cylinder through the distributor to lift the carriage to achieve automatic dumping and cargo dumping Finished, the manipulator to stop the fuel supply to the cylinder, while the fuel tank and the tank connected to the compartment under the weight of a reset. Agricultural truck hydraulic dump system to use more gear pump. Gear pump structure is simple, small size,
