In addition to the quality of the tires, the use of management is also one of the main factors. In order to achieve the purpose of safety (tire failure) and economic (tire life), the correct use of management is the only way, can not be ignored. Details are as follows:
Internal pressure management
1. the influence of internal pressure deficiency:
Because of the increase of the amount of buckling deformation, the temperature of the tire interior increases, so that the strength of the matrix material and the decrease of the bonding force cause the separation of the tread or curtain layer, and even the explosion of the A..
B. excessive flexion, easy to crack (slip groove, tire edges are possible) and curtain yarn broken.
C. because of excessive shaking, resulting in abnormal friction between the fetal lip and steel ring, causing fetal lip injury, and even blasting.
D. fetal lips and steel rings are not closely fitted and cause the injury of the valve tip of the inner tube.
E. easy to produce Li Bo (Standing Wave), and vibration, rotation resistance, and heating, strength, etc..
F. accelerates the wear of the tire shoulder and affects the tire life.
G. internal pressure, tire rotation resistance increases, fuel consumption.
Two, load management
1, the impact of excessive load
A. high load and low internal pressure on the tyre is one of the two sides, so the fault of low internal pressure may occur, high load can also occur, so must pay attention to.
B. high load, easy to wear abnormal wear and affect tire life.
C. is too high to cause the tires to rotate, increase resistance, and burn fuel.
2., the wrong loading mode, in addition to affecting traffic safety, will also be selected as part of the tire load is too high.
Three speed management
1. the impact of high speed tires:
As the speed of A. increases, the driving force, braking force and centrifugal force increase relatively, which results in the increase of tire and road skid, so the wear speed will be accelerated, that is to say, the tire life will be reduced.
With the increase of B. speed, the bending and stretching activities of the tire increase, which makes the calorific value increase and leads to the breakdown.
2. increased speed, rotational resistance and increased air resistance, resulting in increased fuel costs.
3. speed and braking distance:
When the running speed is increased to 2 times, the braking distance must be 4 times. In other words, assuming the speed is 50km/h, the emergency braking distance is 25m, but the speed is increased to 100km/h, then the emergency braking distance is 100m.
Four, duplicate management
1. the weight of the wheel two tires may not be equal for the following reasons:
Drainage design of A. pavement (ARC)
B. rough pavement.
C. tire inflation pressure imbalance.
D. tires are not the same diameter.
Therefore, when the northern V3 fittings tire device in the wheel, it is necessary to reduce its load moderately, in order to reduce the possibility of failure.
2. when the wheel is loaded, the tyre with big outer diameter will be worn out, so the smaller the diameter of the compound wheel, the better the better.
3. when there is an external diameter difference between the multiple wheels, the smaller outer diameter shall be mounted on the inside.
Internal depression, high load, easy to reduce the wheel spacing, or even touch together, this situation will cause poor heat dissipation of the tires and failure.
Five, tire position exchange
1., North V3 fittings, front wheels due to lateral resistance and braking device, prone to partial wear. The rear wheel is more tired due to heavy load, especially the driving wheel. Therefore, if the tire position is properly switched in time, the wear and fatigue can be normalized to promote the tire life.
Note: beiben V3 accessory drive shaft and the guide shaft pattern is different, generally do not arbitrarily replace, but mainly run high-speed vehicles on design requirements are not so strict, can be replaced under the guidance of technical staff.
