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?
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.
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.
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.
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.
The tire of the mixer is still very important. Usually, we should pay more attention to the eccentric wear of the tire and do a good job in the maintenance of the tire of the mixer. Come to our website for more information http://www.zkzsljbc.com Take a look.
