How much suitable for car tire pressure? Is it better to turn up or down?

As the weather began to enter the hot solar terms, the car lovers who were caring for the car began to wonder how to do some cooling work for the car. Summer explosive tires, tire pressure adjustment is essential. Therefore, regarding the controversy over whether summer tire pressure should be adjusted to high or low levels, the following Xiaobian will speak for you.

General car owners have a habit of thinking that summer temperatures are high, thermal expansion and contraction, tire pressure is definitely higher than in winter, heat easily punctured, so it should be low in the tone. It was also pointed out that if the tire pressure is reduced, the friction between the tire and the ground will increase exponentially, the temperature of the tire will rise sharply, the tire will become soft and the strength will drop sharply. In this case, if the vehicle is driving at high speed, it may cause a puncture.

Let's make an analysis to reduce the tire pressure, which will bring two consequences. First, grinding tires will shorten the life of the tires; second, it will increase fuel consumption. In summer, due to the hot weather, especially when driving at high speeds, when the speed reaches 100 to 120 yards, the tread temperature will reach 80°C, or even exceed 100°C, and the internal pressure will increase.

As for increasing tire pressure, the only use is to reduce fuel consumption. However, increasing the tire pressure may cause many disadvantages in addition to possible punctures, such as increased braking distance, which is detrimental to safe driving.

The tire pressure value of a car tire is generally 2.3 to 2.8 BAR. As long as it is within this range, it is safe. However, in summer, when the temperature is high, the tire pressure within the normal range may actually rise above 3.0 BAR after the car is started. Therefore, summer should be taken in the normal tire pressure range is low tire pressure value, 2.3 ~ 2.5BAR more appropriate.

Many newcomers and even veterans are puzzled: how much is my tire pressure normal? Where can I find it? In fact, in addition to the instructions, each car will be marked with standard tire pressure values, and most riders do not pay attention to the place marked by the tire pressure value. This will take some time to find it. Most cars will be stuck on the cab door, some cars will be on the rear door, and some cars will be marked in the fuel tank cap.

Under normal circumstances, the owner should check the tire pressure once a month. Some owners are very busy and often forget to check regularly, so the most worry-free way is to monitor the tire pressure monitor values ​​at any time. Some high-end car manufacturers are equipped with tire pressure monitors and use speed sensors on the car brake system. To compare the number of rotations of the four tires, the principle is that if one of the tires has a low tire pressure, the rotation speed of the tire will inevitably be faster. Through the calculation of the on-board computer, the pressure relief condition of the tire can be known. . However, the disadvantage is that it is impossible to achieve real-time display of tire pressure in 4 tires.

Without a car equipped with tire pressure monitor, direct tire pressure monitoring system should be purchased, such as iron general tire pressure monitor, the tire pressure value at a glance, real-time monitoring of tire pressure and temperature, when the value changes, the tire leaks Gas, tire pressure is too high or too low, the temperature is too high and abnormal conditions, the terminal will automatically alarm, it can also ensure that the tire can be rescued in a timely manner, but also minimizes the risk of traffic safety. Now the tire pressure monitor is also very convenient. The latest external type can establish the connection with the mobile phone by sending and receiving bluetooth signals through the receiver and intuitively embody tire pressure data.

In addition, Xiao Bian also reminded me that the riders who like DIY tire pressure tests should carefully test the tires, because many riders often accidentally mess up the core of the door core and finally make a mistake, leading to tire leaks.

Mechanical properties of injection connector fittings as far as connection functions are concerned, insertion and extraction forces are important mechanical properties. Plug force is divided into insert force and pull out force (pull out force is also called separation force), the requirement of both is different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which indicate that, from the point of view of use, the insertion force should be small (hence the structure of LIF with low insertion force and ZIF without insertion force), and if the separation force is too small, it will affect the reliability of contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, which is called mechanical operation in GB5095. It is based on a cycle of one insert and one pull, and whether the connector can normally complete its connection function (such as contact resistance) after the specified plug cycle. The plug force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the contactor structure (positive pressure size) and the dimensional accuracy (alignment) of the contactor.
