小型攪拌車主要使用在工程建筑中，其作業環境一般都比較差，比如灰塵大、道路高低不平等等，在這樣惡劣的環境中，對攪拌車的影響是非常大的，比如攪拌車的輪胎，道路的高低不平會加速輪胎的磨損，有些攪拌車司機反映說，輪胎的偏磨比較嚴重，尤其是前輪。那這到底是怎么回事呢？

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?

很多人認為攪拌車輪胎的偏磨是車輪的外傾角超差造成的，但其實輪胎的偏磨在很大程度上是因前束值的超差造成的，根據從事四輪定位工作多年的技術人員總結的經驗和大量的定位檢測數據分析認為：正確的前束值完全可以有效的避免輪胎的偏磨。

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.

還有一種輪胎偏磨是轉向輪大總轉角的超差、車輪外傾角和主銷傾角的不正確導致的，攪拌車在實際的行駛中，大多數是直線行駛的，轉彎、倒車和掉頭時的大總轉角的時間不多，所以由此引發的偏磨比較少。

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.

攪拌車輪胎與地面接觸時的柔韌性和隨意變形的特性很大程度上抵消了因車輪外傾角可能造成的輪胎偏磨，即便是高壓輪胎超差的車輪外傾角對輪胎的磨損影響也不大，有很多的廂式貨車在空車的時候為了減少輪胎與地面的摩擦、降低滾動阻力而專門設計了可變后輪外傾角。

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.

從設計上考慮，為了約束攪拌車在直線行駛中車輪外傾角造成的輪胎偏磨，對攪拌車設定了一定的前束值，由于攪拌車行駛不同的路面情況和顛簸、沖撞、機件磨損等因素的存在，即使是堅固的攪拌車，它原有的定位角度都要不同程度的因上述原因逐漸改變原前束值。有的數值一發生變化，在行駛過程中就能感覺到，比如主銷后傾角、車輪外傾角、比較嚴重的后輪前束值的改變。

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.

攪拌車的輪胎還是很重要的，平時要多注意輪胎的偏磨問題，做好攪拌車輪胎的保養。更多有關事項就來我們網站http://www.www.boy7up.cn看看吧。
