自动上料搅拌车在工作很长时间之后，可能会出现仪表台、驾驶室抖动现象，且抖动现象越来越严重，以至驾驶室、整机也产生抖动。抖动现象造成该机物料称重不准确，无法正常使用。下面技术人员给大家分析一下引起抖动的原因有哪些？

After the automatic feeding mixer works for a long time, the instrument panel and cab may shake, and the shaking phenomenon is getting more and more serious, so that the cab and the whole machine also shake. The shaking phenomenon causes the material weighing of the machine to be inaccurate and cannot be used normally. The following technicians will analyze the causes of jitter?

1、自动上料搅拌车液压系统采用转向优先方式，转向泵输出的压力油与工作泵输出的压力油合流后向工作装置供油。工作泵只有在工作装置动作时才承受负荷，而转向泵不但在工作装置动作时承受负荷，转向时也承受负荷，因此转向泵工作时间相对较长、磨损较大。

1. The hydraulic system of the automatic feeding mixer adopts the steering priority mode. The pressure oil output from the steering pump and the pressure oil output from the working pump combine to supply oil to the working device. The working pump bears the load only when the working device acts, while the steering pump bears the load not only when the working device acts, but also when steering, so the steering pump has a relatively long working time and great wear.

2、自动上料搅拌车在优先阀阀体、阀芯、调压弹簧和压力油的共同作用下，EF口开启与闭合按照一定频率相互变换，便发生一定频率的振动。由于该振动与仪表台、驾驶室的固有振动频率接近，导致仪表台、驾驶室发生共振。

2. Under the joint action of the priority valve body, valve core, pressure regulating spring and pressure oil, the opening and closing of EF port of the automatic feeding mixer change with each other according to a certain frequency, and a certain frequency of vibration occurs. As the vibration frequency is close to the natural vibration frequency of the instrument panel and cab, the instrument panel and cab will resonate.

此外自动上料搅拌车负载感应变速控制系统能缩短作业循环，降低燃油消耗率达15%，提高作业效率和作业经济性同时能减少因行驶方向改变或因发动机处于高转速时换挡所造成的换挡冲击，减轻司机的工作疲劳。

In addition, the load sensing speed change control system of the automatic feeding mixer can shorten the operation cycle, reduce the fuel consumption by 15%, improve the operation efficiency and operation economy, reduce the shift impact caused by the change of driving direction or the shift when the engine is at high speed, and reduce the driver's fatigue.

连杆机构可承受大的扭矩载荷，具有可靠性、耐用性和平行举升机构相类似的作业性能工作装置能以水平位置提升或降下放在托板上的物料，可配用多种作业装置，大限度地减少司机由地面到大高度对铲斗倾斜角的调整。

The linkage mechanism can bear large torque load, and has reliability, durability and similar operating performance to the parallel lifting mechanism. The working device can lift or lower materials on the pallet in a horizontal position, and can be equipped with a variety of operating devices to greatly reduce the driver's adjustment of the bucket tilt angle from the ground to a large height.
