Some data show that the proportion of car accidents caused by explosive tires is as high as 70%in the evil accident, and the tire pressure in all factor that will cause explosive tires is the primary cause.This is not sensational. Even if you do not choose a model with tire pressure monitoring, you need to increase your attention to vehicle tires and avoid serious damage to people and vehicles.
Principles of tire pressure monitoring
Direct tire pressure monitoring
Direct tire pressure monitoring device is to use the pressure sensor installed in each tire to directly measure the air pressure of the tire. Use a wireless transmitter to send the pressure information from the tire inside toEssenceWhen the tire pressure is too low or the air leaks, the system will automatically call the police.
Indirect tire pressure monitoring
The working principle of indirect tire pressure monitoring is that when the air pressure of a tire is reduced, the weight of the vehicle will make the rolling radius of the wheels smaller, resulting in its speed faster than other wheels.By comparing the speed difference between tires, the purpose of monitoring tire pressure.The indirect tire alarm system actually relies on calculating tire rolling radius to monitor air pressure.
Tire pressure monitoring characteristics
These two tire pressure monitoring devices each have advantages.Direct tire pressure monitoring device can provide more advanced functions, and the actual instantaneous pressure inside each tire is determined at any time, which is easy to determine the fault tire.The cost of indirect systems is relatively low, and cars with 4 rounds of ABS (1 rotary sensor equipped with each tire equipment) only need to upgrade the software.However, the indirect tire pressure monitoring device does not have a high system accuracy. It cannot determine the fault tires at all, and the system calibration is extremely complicated. In some cases, the system will not work properly. For example, the two tire pressure of the same car shaft is low.hour.
The main role of tire pressure monitoring
1. Prevent accidents occur
The tire pressure monitoring system is a type of active safety equipment. It can call the police in a timely manner when the tire is in danger, reminding the driver to take corresponding measures to avoid serious accidents.
2. Extend the life of tires
With the tire pressure monitoring system, we can keep the tires in the prescribed pressure and temperature at any time, thereby reducing the damage of the tire and extending the life of the tire.Some information shows that when the tire pressure is insufficient, the wheels air pressure decreases by 10%compared
3. Make driving more economical
When the air pressure in the tire is too low, the contact area between the tire and the ground will be increased, thereby increasing the friction resistance. When the gas pressure value of the tire is 30%lower than the standard gas pressure value, the fuel consumption will increase by 10%.
4. Reduce the wear of the suspension system
When the tires internal gas pressure is too sufficient, the shock absorption effect of the tire itself will be reduced, thereby increasing the burden on the vehicle shock absorption system. Long -term use of the engine chassis and suspension system will cause great damage; if the tire pressure is uneven, it is also easyCauses the brake bias to increase the wear of the suspension system.
Tire pressure monitoring and purchase guide
mechanical
In terms of tire pressure meter, there are generally two types, one is mechanical, and the other is electronic.In the case, the machinery will be cheaper and much durable.However, in the process of use, the careful riders will find that the air pressure value on the valve and after winning will be different. There is a certain error, and even the condition of the tire leakage will affect our use.It has been used for a long time, and it is not accurate to the results of measurement.Therefore, it is best to replace regularly.
Electronic
After knowing what are the characteristics of the mechanical tire pressure meter, what is the electronic class?It is more accurate, but it should not be like mechanical categories when using it. There is no scruple. It is often stunned here and touched that.In fact, you are afraid of too much impact, otherwise it will affect the detection of the air pressure value. Try it as much as possible, so that we can provide us with accurate tire pressure.
Timely transmission of data
The last thing to say is that the tire pressure meter data is transmitted. The electronic tire pressure meter should be feeded in time through the sensor and displayed on the screen. Alert reminder should be issued for a rapid discouraged situation.This can ensure the safety of the tire, to inform the owner of the specific situation of the tire pressure, so as to make the corresponding preparation in advance to avoid accidental traffic accidents and greatly ensure personal safety in the car.
