Under the influence rapid development of the times, the car has been seen everywhere, has become an important tool for everyday travel, we are concerned about in the purchase when the car exterior, interior and performance, and cost-effective, it is more important to consider to security. As more and more cars, traffic accidents have become more frequent, many of them because of traffic accidents caused by tire puncture, the tire is especially important when the vehicle is traveling. For a flat tire that we have a way to prevent what measures? Let’s look at tire pressure monitoring!
First look at tire pressure monitoring, which can be found in tire pressure is normal, if not normal will be issued a warning in advance, giving the driver a warning, thus avoiding tire leak or the occurrence of some of the gas blowouts. Of course, there are many reasons for a puncture, the tire itself is also possible that as a result of quality problems. The most common tire pressure monitoring is divided into: OBD, built-in, external-type tire pressure monitoring three types.
1, OBD type tire pressure monitoring
Most vehicles now have a OBD Interface , when the car is faulty, means for detecting the plug socket of the computer. Installation is very simple, as long as the tire pressure monitoring plug directly on the line. It can not display tire pressure values, when there is only one tire pressure abnormal alarm. Its principle is: within a small chip, it is possible to read values four ABS wheel sensor. The same tire pressure, rotational speed of the four wheels are the same, the air pressure becomes small when a wheel diameter becomes smaller wheels, the wheel speed will be faster than the other wheel, when it exceeds the preset value, it will finds that the wheel pressure less then the alarm. It can only deal with one round less pressure, if the four are missing, not alarm. The tire pressure monitoring is the easiest to install, but also less accurate.
2, built-in tire pressure monitoring
It has two components, a display alarm and tire pressure sensors. Alarm vehicle can be mounted in any position, as long as you can feel on the line, tire pressure sensors are placed inside the tire, each have a sensor in each tire. Tire pressure sensors to monitor tire pressure values, throughOver Bluetooth signals, transmitted to the car display, converts the pressure signal into a digital signal, the display can be seen by the tire pressure when the tire pressure is not a normal alarm automatically. The advantage is that the tire pressure display is very accurate, because the sensor hidden inside the tire, no wind and rain, safety, long life. Do not change the appearance, inflatable not affected, charge anytime, anywhere. The disadvantage: Installation trouble, they can not operate because of the need to separate the tires and wheels to install into, we need to repair shop. Note that, if it is because tire repair or replacement of tires and other reasons, need to remove tires, must we talk about the mechanics, the installation of tire pressure monitoring, because they can not see from the outside, if not pay attention, it is easy to disassemble when the tire, the tire pressure sensors broke.
3, tire pressure monitoring external type
It has the same composition and built-in type, is a display alarm and the four tire pressure sensor, tire pressure sensors to the signal transmission is also transmitted to the display tire pressure values, via Bluetooth is more accurate signal. The difference is the built-in mounting position of the tire pressure sensor, it is not attached to the interior of the tire, but directly fixed to the valve stem of the original car, can be screwed directly up. The top of the valve core opening sensor, pressure will press onto the sensor, the sensor can monitor the tire pressure. After installation, the valve core is in the top has been opened, the sealing tire pressure sensors rely on tire air pressure and the internal sensor are interlinked.
It is the advantage of easy installation, and that they can be operated, which is written on the sensor wheel, the wheel on which it can be screwed into, requires with a special wrench to tighten the nut theft. When tire rotation operation, without re-pair, simply remove the sensor, or can be placed in the original position. Its disadvantage is the appearance of unsightly, exposed valve stem of a plurality of tire pressure sensors, met easily damaged. Inflatable is not easy, every time the sensor can be removed when inflated to charge, so there is a dedicated breakout wrench onboard will not be lost, otherwise it can not be inflated. Whether built-in or external, as are more than one thing on wheels, the original dynamic balance will be destroyed, high speed could cause the steering wheel shake, shake, if, you need to make aFour-wheel balancing.
