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?
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.
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.
