1. When the mixer controls the steering wheel on the way

这是抖动，一般在搅拌车中速以上速度行进时，底盘有规律性的响声，严峻时驾驶室和车门发抖，方向盘强烈震动，导致手发麻，这是方向传动装置动平衡被损坏了，搅拌车传动轴及其花键轴和花键套磨损过度引起的。

This is shaking. Generally, when the mixer is moving at medium speed or above, the chassis makes regular noise. When it is severe, the cab and the door shake. The steering wheel vibrates strongly, resulting in hand numbness. This is caused by the damage of the dynamic balance of the direction transmission device and the excessive wear of the drive shaft, spline shaft and spline sleeve of the mixer.

2、搅拌车在转向的时分沉重费力

2. The mixer is heavy and laborious when turning

这种现象产生的原因有：转向系统各部位的滚动轴承及滑动轴承合作过紧，轴承光滑不良，转向纵拉杆、横拉杆的球头调的过紧或许缺油，转向轴及套管弯曲，造成卡滞，前轮前束调整不妥，前桥或许车架弯曲、变形，搅拌车的轮胎胎压不足。

The reasons for this phenomenon are: the cooperation of rolling bearing and sliding bearing in all parts of the steering system is too tight, the bearing is smooth and poor, the ball joint of steering longitudinal rod and tie rod is too tight or lack of oil, the steering shaft and sleeve are bent, causing stagnation, the front toe in adjustment is not proper, the front axle or frame is bent and deformed, and the tire pressure of the mixer is insufficient.

3、搅拌车的方向盘欠好操纵

3. The steering wheel of the mixer is not easy to operate

在搅拌车的行进过程中，方向盘会主动的向道路一边偏，造成这种现象的原因有几个：两边的前轮规格不一致，两边的钢板弹簧拱度或弹力不一致，左右两边轴距相差不均匀等。

In the process of the mixer's moving, the steering wheel will actively lean to one side of the road, which is caused by several reasons: the specifications of the front wheels on both sides are inconsistent, the camber or spring force of the leaf springs on both sides are inconsistent, and the wheelbase on the left and right sides are not uniform.

4.、搅拌车方向盘发飘

4. The direction of mixer truck is floating

造成这种现象的原因一般是行进中前轮摆头，主要原因是：垫补轮胎或许修补轮胎造成前轮总成动平衡被损坏，搅拌车传动轴总成有零件松动，搅拌车传动轴总成平衡被损坏，减震失效，钢板弹簧刚度不一致，搅拌车转向系机件磨损松懈，前轮校准不妥。

The main reason for this phenomenon is that the front wheel swings its head in the process of moving. The main reason is that the dynamic balance of the front wheel assembly is damaged by patching the tire or repairing the tire. There are loose parts in the drive shaft assembly of the mixer, the balance of the drive shaft assembly of the mixer is damaged, the shock absorption is invalid, the spring rigidity of the steel plate is inconsistent, the steering system parts of the mixer are worn loosely, and the front wheel calibration is improper.
