小型搅拌车主要使用在工程建筑中，其作业环境一般都比较差，比如灰尘大、道路高低不平等等，在这样恶劣的环境中，对搅拌车的影响是非常大的，比如搅拌车的轮胎，道路的高低不平会加速轮胎的磨损，有些搅拌车司机反映说，轮胎的偏磨比较严重，尤其是前轮。那这到底是怎么回事呢？

Small mixers are mainly used in engineering buildings, and their working environment is generally poor, such as heavy dust, uneven roads, etc. in such a harsh environment, the impact on mixers is very great, such as the tires of mixers. Uneven roads will accelerate the wear of tires. Some mixer drivers report that the eccentric wear of tires is serious, especially the front wheels. So what's going on?

很多人认为搅拌车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 believe that the eccentric wear of mixer tires is caused by the out of tolerance camber of wheels, but in fact, the eccentric wear of tires is largely caused by the out of tolerance toe in value. According to the experience summarized by technicians engaged in four-wheel alignment for many years and the analysis of a large number of positioning and detection data, it is believed that the correct toe in value can effectively avoid the eccentric wear of tires.

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，搅拌车在实际的行驶中，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。

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

搅拌车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 camber angle. Even the camber angle of the high-pressure tire with out of tolerance has little effect on the tire wear. Many Van trucks specially designed the variable rear wheel camber angle in order to reduce the friction between the tire and the ground and reduce the rolling resistance when empty.

从设计上考虑，为了约束搅拌车在直线行驶中车轮外倾角造成的轮胎偏磨，对搅拌车设定了一定的前束值，由于搅拌车行驶不同的路面情况和颠簸、冲撞、机件磨损等因素的存在，即使是坚固的搅拌车，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 restrict the tire eccentric wear caused by the camber of the wheels of the mixer truck when driving in a straight line, a certain toe in value is set for the mixer truck. Due to the different road conditions of the mixer truck and the existence of factors such as bumps, collisions, and wear of parts, even a solid mixer truck, its original positioning angle should gradually change the original toe in value to varying degrees due to the above reasons. Some values can be felt during driving as soon as they change, such as kingpin caster, camber, and serious changes in rear wheel toe in.

搅拌车的轮胎还是很重要的，平时要多注意轮胎的偏磨问题，做好搅拌车轮胎的保养。更多有关事项就来我们网站http://www.zkzsljbc.com看看吧。
