小型搅拌机主要适用于建筑工程中，其工作环境相对比较恶劣，灰尘大、道路高低不平等环境是常态，在这样恶劣的环境中，对搅拌机的影响是很大，尤其是对于搅拌机的轮胎，道路的高低不平会加速轮胎的磨损，有些搅拌机司机反映说，轮胎的偏磨比较严重，尤其是前轮。今天我们就来给大家解析下是什么原因造成的这种现象

Small mixers are mainly used in construction projects. Their working environment is relatively bad. It is normal to have large dust and uneven roads. In such a bad environment, the impact on the mixers is great, especially for the tires of the mixers. The uneven roads will accelerate the wear of the tires. Some mixer drivers Report that the tire eccentric wear is serious, especially the front wheels. Today, we will explain to you what causes this phenomenon

很多人认为搅拌机轮胎的偏磨是车轮的外倾角超差造成的，但其实轮胎的偏磨在很大程度上是因前束值的超差造成的，根据从事四轮定位工作多年的技术人员总结的经验和大量的定位检测数据分析认为：正确的前束值完全可以有效的避免轮胎的偏磨。

Many people think that the eccentric wear of the mixer tire is caused by the out of tolerance of the camber angle of the wheel, but in fact, the eccentric wear of the tire is largely caused by the out of tolerance of the toe in value. According to the experience summarized by the technicians engaged in four-wheel positioning for many years and the analysis of a large number of positioning detection data, it is believed that the correct toe in value can effectively avoid the eccentric wear of the tire.

还有一种轮胎偏磨是转向轮大总转角的超差、车轮外倾角和主销倾角的不正确导致的，搅拌机在实际的行驶中，大多数是直线行驶的，转弯、倒车和掉头时的大总转角的时间不多，所以由此引发的偏磨比较少。

Another kind of tire eccentric wear is caused by the out of tolerance of the large total angle of the steering wheel and the incorrect camber angle and kingpin angle. In the actual driving of the mixer, most of them drive in a straight line, and the time of large total angle during turning, reversing and turning is not much, so the eccentric wear caused by this is relatively small.

搅拌机轮胎与地面接触时的柔韧性和随意变形的特性很大程度上抵消了因车轮外倾角可能造成的轮胎偏磨，即便是高压轮胎超差的车轮外倾角对轮胎的磨损影响也不大，有很多的厢式货车在空车的时候为了减少轮胎与地面的摩擦、降低滚动阻力而专门设计了可变后轮外倾角。

The flexibility and random deformation of the mixer tire when contacting the ground largely offset the tire eccentric wear caused by the wheel camber angle. Even if the wheel camber angle of the high-pressure tire is out of tolerance, it has little impact on the tire wear. Many Van trucks specially designed variable rear wheel camber angle to reduce the friction between the tire and the ground and reduce the rolling resistance when they are empty.

从设计上考虑，为了约束搅拌机在直线行驶中车轮外倾角造成的轮胎偏磨，对搅拌机设定了一定的前束值，由于搅拌机行驶不同的路面情况和颠簸、冲撞、机件磨损等因素的存在，即使是坚固的搅拌机，它原有的定位角度都要不同程度的因上述原因逐渐改变原前束值。有的数值一发生变化，在行驶过程中就能感觉到，比如主销后倾角、车轮外倾角、比较严重的后轮前束值的改变。

From the design point of view, in order to restrain the tire eccentric wear caused by the camber angle of the wheel when the mixer is running in a straight line, a certain toe in value is set for the mixer. Due to the different road conditions of the mixer and the existence of factors such as bumping, collision and mechanical wear, even the original positioning angle of the solid mixer will gradually change the original toe in value due to the above reasons. Some values can be felt during driving as soon as they change, such as caster angle of kingpin, camber angle of wheel, and serious toe in value of rear wheel.

搅拌机的轮胎在行驶中尤为重要，所以在日常维护中一定要注意轮胎的保养，比如说规定时间一月中什么时候去修理厂去看看，平常中也要多多检查搅拌机的各个部件，毕竟很多问题都是从部件出现的故障的。更多注意事项您可以来我们网站https://www.zishangliaojiaobanji.cn咨询。

The tires of the mixer are particularly important in safe driving, so it is necessary to pay attention to the maintenance of the tires in daily maintenance. For example, go to the repair shop at the specified time in the middle of January, and check all parts of the mixer frequently. After all, many problems are caused by the failure of the parts.
