大型自上料水泥攪拌車輪胎容易出現問題嗎?

大型自上料水泥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,比如大型自上料水泥攪拌車的輪胎,道路的高低不平會加速輪胎的磨損,輪胎的偏磨比較嚴重,尤其是前輪。這到底是怎么回事呢?
Large concrete mixer is mainly used in engineering construction, and its working environment is generally poor, such as large dust, uneven road and so on. In such a bad environment, the impact on the mixer is very large, such as the tire of large concrete mixer, the uneven road will accelerate the tire wear, the tire eccentric wear is more serious, especially the front wheel. What's going on?
很多人認為大型自上料水泥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。還有一種輪胎偏磨是轉向輪zui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zui大總轉角的時間不多,所以由此引發的偏磨比較少。

Many people think that the eccentric wear of the tire of large concrete mixer is caused by the out of tolerance of camber angle of the wheel, but in fact, the eccentric wear of the tire is caused by the out of tolerance of toe in value to a large extent. According to the experience summarized by the technicians who have been 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. Another kind of tire eccentric wear is caused by the out of tolerance of steering wheel Zui's big total angle, the incorrect camber angle and kingpin angle. In the actual driving, most of the agitators are driving in a straight line, and the time of Zui's big total angle when turning, reversing and turning is not much, so the resulting eccentric wear is relatively less.
大型自上料水泥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。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,由于大型自上料水泥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zui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。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。
The flexibility and random deformation of large concrete mixer tire in contact with the ground largely offset the tire eccentric wear caused by wheel camber. Even if the wheel camber of high-pressure tire is out of tolerance, it has little impact on tire wear. Many vans are specially designed to reduce tire friction with the ground and rolling resistance when empty Variable rear camber is taken into account. From the design point of view, in order to restrict the tire eccentric wear caused by the wheel camber angle of the mixer during the straight-line driving, a certain toe in value is set for the mixer. Due to the different road conditions of the large concrete mixer driving and the existence of bumps, collisions, machine wear and other factors, that is to say, Zui solid mixer, its original positioning angle should be different degrees because of the above reasons one by one Gradually change the original toe in value. As soon as some values change, it can be felt during driving, such as caster angle, camber angle, and more serious change of rear wheel toe in value. The tires of the mixer are still very important. Usually, we should pay more attention to the eccentric wear of the tires and do a good job in the maintenance of the tires of the mixer.
