Since today's tire mixing, we have been paying attention to the selection of small tire materials

自上料搅拌车等工程机械的轮胎选用主要应满足：保证工作负荷、在载重条件下达到允许的车速及在正常的使用工况下滚动阻力小、牵引性好、使用寿命长等要求。

The tire selection of construction machinery, such as self loading mixer, should meet the following requirements: ensuring working load, reaching the allowable speed under load conditions, small rolling resistance, good traction and long service life under normal working conditions.

工程机械轮胎的规格与使用范围，有专门的标准，自上料搅拌车通常选用低压宽基轮胎，按国标中第三类使用类型的相关参数进行选用，该类主要用于短距离装运，作业速度慢、运输距离短，车速10km／h，单程运距不超过75m的工程机械。

There are special national standards for the specifications and application scope of construction machinery tires. The low-pressure wide base tire is usually selected for the self loading mixer truck according to the relevant parameters of the third use type in the national standard. This kind of tire is mainly used for construction machinery with short distance shipment, slow operation speed, short transportation distance, speed of 10km / h and one-way transportation distance of 75m.

同时，轮胎的胎面花纹的选择也十分重要，其作用是传递工程机械的牵引力和制动力。对轮胎的与路面的附着性能、耐磨耗性能、滚动阻力等均有很大的影响。轮胎使用条件不同，对花纹的要求也不同。

At the same time, the selection of tire tread pattern is also very important, its role is to transfer the traction and braking force of construction machinery. It has a great influence on the adhesion, wear resistance and rolling resistance of the tire to the road surface. The requirements of tread patterns are different with different tire service conditions.

为保证车辆性能，通常胎面花纹应满足：特定的使用条件，满足车辆性能的要求；胎面与路面有良好的附着力；胎面抗滑性能和耐磨耗性能好、滚动阻力小；花纹中不夹带泥沙和石子，有较好的自洁性能；耐切割，不崩花掉块，不裂口等要求。在满足特定的使用条件下，还应有较好的综合性能和较高的使用寿命。

In order to ensure the vehicle performance, the tread pattern should meet the following requirements: specific use conditions, meet the requirements of vehicle performance; good adhesion between the tread and the road surface; good skid resistance and wear resistance of the tread; good self-cleaning performance without sand and stone in the tread pattern; good cutting resistance, no chipping, no cracking, etc. In order to meet the specific service conditions, it should also have better comprehensive performance and longer service life.

自上料搅拌车常用的轮胎胎面花纹与相应的适用条件如下：

The common tread patterns and corresponding applicable conditions of self loading mixer are as follows:

牵引花纹（L—2）：适用于在松软、泥泞的地面上的作业工况。能发挥极大的牵引力，并有较好的自洁性能。块状花纹（L—3）：适用于多种条件下的作业工况，具有一定的耐磨损和抗切割性能。

Traction pattern (L-2): suitable for working on soft and muddy ground. It can play a great traction force and has good self-cleaning performance. Block pattern (L-3): suitable for various working conditions, with certain wear resistance and cutting resistance.

块状加深花纹（L—4）：适用于较苛刻条件下的作业工况，具有较好的耐磨损和抗切割性能。可延长轮胎的使用寿命。块状超加深花纹（L—5）：适用于多岩石等苛刻条件下的作业工况，具有较好的耐切割和抗刺穿性能。并具有良好的稳定性能和牵引性能。

Block deepening pattern (L-4): it is suitable for working conditions under severe conditions, with good wear resistance and cutting resistance. It can prolong the service life of tire. Block super deep pattern (L-5): it is suitable for the working conditions under harsh conditions such as many rocks, and has good cutting and piercing resistance. It has good stability and traction performance.

每种轮胎均有其特定的用途和使用特点，通常只能在规定的范围内使用，超出使用范围将引起非正常损坏。因此，若轮胎选用不当，会严重影响轮胎的使用寿命，并影响其使用性能的发挥。具体的装载机轮胎规格及型号的选择是生产厂家根据整机的总体设计要求及负荷情况等来确定的。

Each kind of tire has its specific use and use characteristics, usually can only be used in the specified range, beyond the scope of use will cause abnormal damage. Therefore, if the tire is not selected properly, it will seriously affect the service life of the tire and affect its performance. The specific tire size and model selection is determined by the manufacturer according to the overall design requirements and load conditions of the whole machine.

而轮胎花纹形式厂家所配套的通常为应用范围较广的块状花纹（L—3）。用户可根据自己实际的作业场地的实际情况可提出特殊订货要求或自购合适胎面花纹形式的轮胎。

However, the block pattern (L-3) is usually used in a wide range of applications. Users can put forward special order requirements or purchase tires with suitable tread pattern according to the actual situation of their own actual operation site.
