Working principle of hydraulic system of dump truck
In the dump truck with some hydraulic steering device, because the lift mechanism is parking condition, so also use its steering pump and lift pump for hydraulic system oil pump lift mechanism, in order to get more oil flow. When lifting, cut off the passage between the steering pump and the steering booster so that the oil output from the steering pump is applied to the tilting cylinder by the booster valve.
The utility model is mainly composed of a lifting cylinder, a control valve, a lifting control valve, a limit valve and an elevating oil pump. The tilting of the tilting mechanism is accomplished by lifting the lift cylinder. The operation of the tilting cylinder is controlled by the control valve, and the control valve is operated by the driver to limit the maximum inclination angle of the container, and the container can be stabilized at an inclined position as required, and a limit valve is arranged in the hydraulic system.
The automatic tipping box of the dump truck is realized by a special tilting mechanism. At present, hydraulic tilting mechanism is widely adopted in large tonnage dump trucks.
