自動上料攪拌車在工作很長時間之后，可能會出現(xiàn)儀表臺、駕駛室抖動現(xiàn)象，且抖動現(xiàn)象越來越嚴重，以至駕駛室、整機也產(chǎn)生抖動。抖動現(xiàn)象造成該機物料稱重不準確，無法正常使用。下面技術(shù)人員給大家分析一下引起抖動的原因有哪些？

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、自動上料攪拌車液壓系統(tǒng)采用轉(zhuǎn)向優(yōu)先方式，轉(zhuǎn)向泵輸出的壓力油與工作泵輸出的壓力油合流后向工作裝置供油。工作泵只有在工作裝置動作時才承受負荷，而轉(zhuǎn)向泵不但在工作裝置動作時承受負荷，轉(zhuǎn)向時也承受負荷，因此轉(zhuǎn)向泵工作時間相對較長、磨損較大。

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、自動上料攪拌車在優(yōu)先閥閥體、閥芯、調(diào)壓彈簧和壓力油的共同作用下，EF口開啟與閉合按照一定頻率相互變換，便發(fā)生一定頻率的振動。由于該振動與儀表臺、駕駛室的固有振動頻率接近，導致儀表臺、駕駛室發(fā)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.

此外自動上料攪拌車負載感應變速控制系統(tǒng)能縮短作業(yè)循環(huán)，降低燃油消耗率達15%，提高作業(yè)效率和作業(yè)經(jīng)濟性同時能減少因行駛方向改變或因發(fā)動機處于高轉(zhuǎn)速時換擋所造成的換擋沖擊，減輕司機的工作疲勞。

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.

連桿機構(gòu)可承受大的扭矩載荷，具有可靠性、耐用性和平行舉升機構(gòu)相類似的作業(yè)性能工作裝置能以水平位置提升或降下放在托板上的物料，可配用多種作業(yè)裝置，大限度地減少司機由地面到大高度對鏟斗傾斜角的調(diào)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.
