搅拌车使用时间久了偶尔也会出现这样那样的故障，很多时候在发生故障之前都是有一些不正常的表现的，所以一些细心的搅拌车司机总是能够提前发现问题，这样就尽可能的避免了一些大型故障的出现，让搅拌车工作起来事半功倍。

The mixer truck has been used for a long time and occasionally has such and such failures. Most of the time, there are some abnormal performances before the failure, so some careful mixer truck drivers can always find the problems in advance, so as to avoid some large failures as far as possible and make the mixer truck work with half the effort.

今天由搅拌车的人员给我们讲解一下怎么从方向盘上判断出故障问题。

Today, the personnel of the mixer truck will explain to us how to judge the fault from the steering wheel.

搅拌车在行驶途中控制方向盘时手发麻，这是抖动，一般在搅拌车中速以上速度行驶时，底盘有规律性的响声，严重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破坏了，搅拌车传动轴及其花键轴和花键套磨损过度引起的。

When the mixer truck controls the steering wheel during driving, the hands become numb, which is caused by shaking. Generally, when the mixer truck runs at a speed above the medium speed, the chassis makes a regular sound. In serious cases, the cab and door tremble, and the steering wheel vibrates strongly, resulting in hand numbness. This is caused by the damage of the dynamic balance of the steering gear, and the excessive wear of the mixer truck transmission shaft, its spline shaft and spline sleeve.

2. 搅拌车在转向的时候沉重费力，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配合过紧，轴承润滑不良，转向纵拉杆、横拉杆的球头调的过紧或者缺油，转向轴及套管弯曲，造成卡滞，前轮前束调整不当，前桥或者车架弯曲、变形，搅拌车的轮胎胎压不足。

2. the mixer truck is heavy and laborious in steering. The reasons for this phenomenon are: the rolling bearings and sliding bearings at various parts of the steering system are too tight, the bearings are poorly lubricated, the ball joints of the steering longitudinal and tie rods are adjusted too tight or lack of oil, the steering shaft and sleeve are bent, resulting in stagnation, improper adjustment of the front wheel toe in, bending and deformation of the front axle or frame, and insufficient tire pressure of the mixer truck.

3. 搅拌车的方向盘不好操纵，在搅拌车的行驶过程中，方向盘会自动的向道路一边偏，造成这种现象的原因有几个：两侧的前轮规格不一致，两侧的钢板弹簧拱度或弹力不一致，左右两侧轴距相差不均匀等。

3. the steering wheel of the mixer truck is not easy to operate. During the driving process of the mixer truck, the steering wheel will automatically deviate to one side of the road. There are several reasons for this phenomenon: the specifications of the front wheels on both sides are inconsistent, the camber or elasticity of the leaf springs on both sides are inconsistent, and the wheelbase difference between the left and right sides is uneven.

4. 搅拌车方向盘发飘，造成这种现象的原因一般是行驶中前轮摆头，主要原因是：垫补轮胎或者修补轮胎造成前轮总成动平衡被破坏，搅拌车传动轴总成有零件松动，搅拌车传动轴总成平衡被破坏，减震失效，钢板弹簧刚度不一致，搅拌车转向系机件磨损松散，前轮校准不当。

4. the steering wheel of the mixer truck floats. The main reason for this phenomenon is that the front wheel swings during driving. The main reasons are: the dynamic balance of the front wheel assembly is damaged due to tyre padding or tyre repair, parts of the transmission shaft assembly of the mixer truck are loose, the balance of the transmission shaft assembly of the mixer truck is damaged, the shock absorption is invalid, the stiffness of the leaf spring is inconsistent, the steering components of the mixer truck are worn loose, and the front wheel is improperly calibrated.

不管是搅拌车还是随车吊，它的一些小小异常就可能是潜在的故障，希望各位专用车友们平时开车一定要细心。

Whether it's a mixer truck or a truck mounted crane, some of its small abnormalities may be potential faults. I hope you special purpose drivers will drive carefully at ordinary times.
