The use of tyres is unusual, so truck drivers who work hard can ignore the small details, and tyres are a cost-effective waste, with emphasis on the small details of the use of tyres, which not only guarantee safety but also have good economic effects。
Tyre examination: tyre side and inner liner
Any re-inflating of tyres and rotor assemblies may result in serious personal injury or injury after a leak or inflating condition (with a tire pressure equal to or below 80 per cent of the recommended value). The interior of the tyre may have been damaged and exploded during inflating. The rims may be worn, damaged or dislocated and may be disengaged at the time of the explosion. Tyres can only be repaired after inflating and after careful examination of their internal condition。
In the visual examination of previously used tyres, the side and internal liner of tyres should be thoroughly examined, so that potential damage that may lead to the end-of-life of tyres may be identified. On the inner liner, check if there are bruises, wrinkles, colour changes or repairs, and check if there are any changes in drums or broken wires on the outside of the tyre。
Warning: do not inflate a pneumatic tyre before careful internal and external examination of it when it is inflated or leaks。
Tyres and rotor surgeries may be hazardous and must be performed by trained personnel using appropriate tools and following the right steps. Failure to read and comply with all operational steps may result in serious personal injury or injury。
Checkers: any damage or breakdown must be replaced
The condition of the rims must be checked regularly, any damage or break of the rims must be replaced and the rims cannot be repaired using welding. If welding has to be performed, the tyres must be removed from the wheels or there is a risk of explosion. Only when all components return to ambient temperature can they be installed. Wheels must be removed from the vehicle when welded in the background or near the tyre. It is recommended that tyres be pumped before the wheel components are removed。
Replacement of tyres: meeting conditions for use of vehicles and compliance with regulations
When tyre damage can no longer be used, it needs to be replaced. The option of replacing tyres is to purchase new tires, retread them, and sculpt them. When choosing to buy a new baby instead of using it, attention is drawn to:
The replacement tyre shall meet the conditions of use of the vehicle and be capable of being suitable for axle-load conditions and speed of operation of the vehicle. Ensure that tyres are installed in accordance with local regulations。
Double birth: ensure the same size and foetal pressure and not more than 4 mm differential in color
In the use of the twins, in order to avoid abnormal wear and overload problems, it is necessary to confirm that:
They are of the same size, manufacturer and beadline
2. Use the same foetal pressure
3. The difference in the depth of the tyre wreath cannot be greater than 4 mm。
The gas-enhanced doors are installed in the recycle to check the pressure. Ensure that they are properly installed and well fixed (if required) as shown in the figure above。
The higher the tire rolls, the worse the fuel economy
With rolling resistance, tyres are an important factor affecting vehicle efficiency. Rolling resistance is defined as the force required to rotate tyres in kg/t under a given load. For a tyre, an increase in load would lead to increased rolling resistance。
In general, in the 6x4 and 6x2 applications, this tyre rolling resistance accounts for about one third of the vehicle's driving resistance and 3 per cent of the rolling resistance will change fuel consumption by 1 per cent. Air resistance and motion friction are other major obstacles。
Conditions of use also have an important impact on the fuel economy of tyres. The fuel economy is more evident when vehicles with lower rolling drag tyres are used at stable speeds and long distances。
Other factors that may affect tyre rolling resistance:
Tyre wear: the rolling resistance of tyres will be reduced as the depth of the tyre's tread is reduced. The tires are the most fuel-efficient when they are the shallowest. This is why guttering is important for a comprehensive tyre maintenance plan。
(b) tire pressure: the rolling resistance of tyres increases when the pressure lowers below the value required for load. If the tire pressure increases above the value required for the load, the rolling resistance will be reduced slightly. Despite minor improvements in rolling resistance, excessive foetal pressure will lead to a significant reduction in the wear and durability of the tyre。
3. Speed: rolling resistance is close to constant within 60-90 km/h. Speed above this range will lead to a significant increase in air resistance and will significantly reduce fuel economy。
Temperature: when the temperature is lower, the rolling resistance is higher. When the vehicle is first activated in the morning, tyres will take up to one hour to reach a stable temperature, and therefore the rolling resistance will be reduced during the preheating time of the tyres。
Of course, there must be more experience for the old drivers who are running out of the country all the time, and it is possible to leave a message to you that, in the face of this bleak market this year, we are confident that your wisdom will keep us in the market。
