Embodiment Construction
[0019] The specific implementation will be described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, the steering hydraulic system in this embodiment is the steering hydraulic system of the loader, which includes a variable pump 2, an electric proportional control valve 13, a flow amplification valve 7, a steering cylinder 8, and a hydraulic oil tank 1. The hydraulic oil tank 1 is used to store The hydraulic oil used in the hydraulic system is installed; the variable pump 2 draws hydraulic oil from the hydraulic oil tank 1 and pumps it out from its oil outlet, the load feedback port X on the variable pump 2 obtains the load signal, and the variable pump 2 pumps the appropriate oil according to the load signal flow of hydraulic oil.
[0021] The flow amplifying valve 7 is used to control the expansion and contraction of the steering oil cylinder 8 to realize steering. The flow amplifying valve 7 has an oil inlet HP connected to the oil...

The invention relates to a steering hydraulic system and a loader. In order to solve the problem that the existing loader has too many steering turns and easily cause operational fatigue, it provides a steering hydraulic system for a loader, including a controller, a steering handle, an electric proportional control valve and an electromagnetic switch. valve group, one-way throttle valve group, and steering operation detection device of the steering gear; the controller controls the electric proportional control valve to output steering pilot pressure oil according to the steering electric signal output by the steering handle; the electric proportional control valve passes through the electromagnetic switch valve group 1. The steering gear is connected to the steering control end of the flow amplifying valve through the one-way throttle valve group; when the steering gear has a steering operation, the controller controls the electromagnetic switch valve group to be in the cut-off position. In the present invention, in addition to performing normal steering operations by turning the steering wheel, the operator can also perform steering operations by operating the steering handle when the loader frequently turns in a fixed field. Steering by the steering handle has low labor intensity and is suitable for Frequent steering operations.
Description
technical field [0001] The invention relates to a steering control, in particular to a steering hydraulic system and a loader. Background technique [0002] For existing operating machinery, such as loaders, forklifts, etc., such machinery is equipped with a steering hydraulic system, the steering hydraulic system includes a steering gear driven by the steering wheel, a flow amplification valve connected to the steering gear, controlled by the flow amplification valve Steering cylinders, etc. In this type of steering system, the operator achieves steering control by turning the steering wheel. However, for some operating machinery operating in a fixed area, for example, when a loader loads and unloads materials in a mine, its running track is basically fixed, and the steering operation of the loader is also basically fixed. In order to improve the working efficiency of the machine, the loader is usually required to achieve fast steering, which requires the operator to turn...
