The tire is an important component in the entire electric vehicle.
It supports the full weight of the vehicle and bears the load of the vehicle; it transmits the torsion force of traction and braking to ensure the adhesion of the wheels and the road surface; it reduces and absorbs the vibration and absorption of the vehicle during driving. The impact force prevents the auto parts from violent vibration and early damage. So as to ensure the handling stability, driving safety, comfort and energy saving economy. Such an important part, the maintenance and overhaul of electric vehicles cannot be ignored.
Among them, the tires are divided into vacuum tires and ordinary tires. Tubeless tires are tires without inner tubes. When the vehicle is moving at high speed, the amount of change is small, and it can maintain good driving stability and low friction, which is conducive to the absorption of shock and impact. And the increase in vehicle speed.
Tubeless tires are much thicker than ordinary tube-type tires, and there is a layer of high-quality rubber on the surface. After inflation, the surface tension increases, and a certain pressure is formed on the inner surface, which improves the self-sealing ability to the breach. Once punctured, it is not like The gas of ordinary tires is completely exhausted in an instant, and it will last for a certain period of time, ensuring completeness during high-speed driving.
Pay attention to
The tire pressure of the tire during normal use. Generally, the speed of the car is very fast, and the shape of the tire is in a high-frequency alternating state. If the air pressure is insufficient, the deformation will increase, the tread pattern on both sides of the tread will be excessively worn, and the carcass will be twisted and deformed because it cannot withstand the pressure on the ground. , Generating high temperature and accelerating tire wear, eventually leading to a puncture.
Regularly check the tires for damage and remove any embedded objects that may penetrate the carcass. Because they may severely damage the carcass. It has a great impact on the life of electric vehicle tires. If you find protrusions and unevenness on the side and bottom of the tire; excessive wear on the bottom of the tire; cuts, splits, and cracks on the bottom, replace these tires.
When people often use electric vehicles as a travel tool, the bike tire are often the most worn out during travel. Because the bike tire are in contact with the ground for a long time during riding, coupled with the impact of different road sections, the wear and tear of the bike tire is great; its condition is good or bad It will directly affect driving safety, from choosing bike tire to judging the degree of wear is particularly important.
There are also big differences in structure and naming . Electric vehicle bike tire generally uses tubeless bike tire , steel to wire bike tire , radial bike tire , and bias bike tire . Tubeless bike tires are mainly composed of outer tread (rubber ) and plies (nylon ) ; of course , steel tubeless bike tire are also better quality and more secure bike tire . For bias bikes to tire , the plies is used to stagger each other , and the diagonal intersections increase stability . For radial bike tire , the plies is arranged vertically like the warp of the earth , and are 90 degrees to the center of the tread , thereby increase the grip .
The main factors of us to choose tires include wear resistance and grip , which can achieve the best balance under consideration of many factors ; electric vehicle tires use steel wire vacuum tires , and the outer tires are thickened with four layers of stab-resistant materials . , The main non-slip rubber layer , puncture-resistant metal braided layer , metal sealing steel ring , cord layer ; thicker tires , safe and secure
Usually when the degree of wear reaches a certain level, the tires must be replaced in time; cracks on the surface of the electric bicycle tires will also become a safety hazard. Perhaps the cracks in the tires at the beginning have little effect on riding, but after a long period of riding After that, it will not only damage the inner tube, but also cause the risk of bulging or puncture. Therefore, when we find obvious cracks, we should replace it in time. Generally speaking, the service life of electric vehicle tires is about 5 years, of course, it depends on the daily traffic conditions; after a certain number of years, the electric vehicle tires will begin to age, and continued use will cause the tread to deform and cause explosions.
Replacement of electric vehicle tires:
1. Generally, electric vehicle tires are replaced after they have passed their service life. The service life of electric vehicle tires is generally about three years. 2. When the tire is found to be worn to the limit mark at the bottom of the groove, the tire should be replaced. 3. The tire should be replaced when there is a crack in the tire of the electric car. 4. If the electric vehicle has a bulging phenomenon, it is necessary to go to a regular repair shop for professional inspection and replacement. 5. When the white steel wire appears on the tire surface due to excessive wear, it indicates that its various performances are already very weak, which affects the comfort and safety of the vehicle. At this time, new tires must be replaced.
