Some concrete mixer truck owners will encounter this situation in the process of using concrete mixer truck: there will be a periodic sound during driving. The faster the driving speed is, the louder the sound is. When it's serious, the whole body is shaking. You can feel numb when holding the steering wheel in the cab. Such a situation indicates that the vehicle has been "sick". What is the problem? What are the reasons for the shaking of the mixer truck?

造成攪拌車振抖的原因有：

The causes of shaking of mixer truck are as follows:

一、傳動軸的彎曲；

1、 Bending of transmission shaft;

二、萬向節(jié)損壞，安裝不合要求；

2、 The universal joint is damaged and the installation is unqualified;

三、傳動軸上原平衡塊脫落；

3、 The original balance weight on the transmission shaft falls off;

四、中間支撐固定螺栓松動；

4、 The fixing bolts of the intermediate support are loose;

五、中間支承軸承偏斜；

5、 Deflection of intermediate support bearing;

六、傳動軸的凸緣和軸管焊接時位置歪斜；

6、 The position of the flange of the transmission shaft is skewed when welding with the shaft tube;

以上六點是造成混凝土攪拌車車身發(fā)生抖動的原因，逐一排查以上可能出現(xiàn)的故障，然后對應，就能使混凝土攪拌車恢復正常狀態(tài)。

The above six points are the reasons for the shaking of the concrete mixer truck body. Check the above possible faults one by one, and then solve them accordingly, so that the concrete mixer truck can return to normal state.

攪拌車罐怠速不轉是什么原因？

What is the reason why the mixing tank does not rotate at idle speed?

攪拌車攪拌罐的低工作轉速是不能低于650轉/分，按照重型底盤發(fā)動機的設計參數(shù)可知它的正常工作轉速為950轉/分，在工作過程中，如果出現(xiàn)混凝土攪拌車罐怠速不轉，我們可以從以下三個方面著手，我們一起來看看可能會導致攪拌車罐怠速不轉的三個原因：

The low working speed of the mixing tank of the mixer truck can not be lower than 650 rpm. According to the design parameters of the heavy chassis engine, its normal working speed is 950 rpm. In the process of work, if the concrete mixing tank idles, we can start from the following three aspects. Let's take a look at the three reasons that may lead to the idling of the mixing tank:

一、看一下液壓油是否干凈，在散熱器上有一個負壓表，如果表針指到紅色區(qū)域表示該換油換濾芯了；

1、 Check whether the hydraulic oil is clean. There is a negative pressure gauge on the radiator. If the gauge needle points to the red area, it indicates that it is time to change the oil and filter element;

二、也有可能表頭出現(xiàn)故障，可直接查看一下，液壓是否發(fā)黑，或者乳化；

2、 There may also be a fault in the meter. You can directly check whether the hydraulic pressure is blackened or emulsified;

三、測試壓力，看有無液壓梭閥堵塞現(xiàn)象，好有人員現(xiàn)場確認。

3、 Test the pressure to see if the hydraulic shuttle valve is blocked, so that personnel can confirm it on site.

以上三個原因會導致混凝土攪拌機罐怠速不轉，車主朋友們可根據(jù)情況逐一排查及問題。

The above three reasons will lead to the idling of the concrete mixer tank. The friends of the owner can check and solve the problems one by one according to the situation.
