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?

造成搅拌车振抖的原因有：

The causes of shaking of mixer truck are as follows:

一、传动轴的弯曲；

1、 Bending of transmission shaft;

二、万向节损坏，安装不合要求；

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

三、传动轴上原平衡块脱落；

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

四、中间支撑固定螺栓松动；

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

五、中间支承轴承偏斜；

5、 Deflection of intermediate support bearing;

六、传动轴的凸缘和轴管焊接时位置歪斜；

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

以上六点是造成混凝土搅拌车车身发生抖动的原因，逐一排查以上可能出现的故障，然后对应，就能使混凝土搅拌车恢复正常状态。

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.

搅拌车罐怠速不转是什么原因？

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

搅拌车搅拌罐的低工作转速是不能低于650转/分，按照重型底盘发动机的设计参数可知它的正常工作转速为950转/分，在工作过程中，如果出现混凝土搅拌车罐怠速不转，我们可以从以下三个方面着手，我们一起来看看可能会导致搅拌车罐怠速不转的三个原因：

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、看一下液压油是否干净，在散热器上有一个负压表，如果表针指到红色区域表示该换油换滤芯了；

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、也有可能表头出现故障，可直接查看一下，液压是否发黑，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、测试压力，看有无液压梭阀堵塞现象，好有人员现场确认。

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

以上三个原因会导致混凝土搅拌机罐怠速不转，车主朋友们可根据情况逐一排查及问题。

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.
