Generally, the main reason for the hot tire bolts of the truck should be the brake of the car. A lot of heat is generated by car braking, and the heat will be transferred to the tire bolts, causing the bolts to be hot. In particular, if the car brake is jammed or delayed, and the brake element cannot be released in time, the heat generated will be greater, the temperature will be higher, and the temperature of the brake hub and tire bolt will also be higher, which will bring hidden dangers to the safe driving of the car.
Truck tire bolts are hot
For example, if the car bolts are loosened and broken, the bolts will produce heat decay, causing tire blowout, and so on. So in normal driving, we should check and maintain the car brake system in time to make it work normally at all times to avoid unnecessary trouble. So, in cars, is it only the brake of the car that causes the heat of the tire bolt? What other factors can cause car bolts to heat or even burn? This starts with the structural properties of the metal and the stress of the tire bolts.
As you know, the main element of automotive bolts is iron, and iron is composed of an infinite number of iron atoms. Many iron atoms can squeeze and move with each other under the action of strong external force, and friction and heat will be generated by mutual movement, which is also the reason why metal materials have ductility. Of course, this is another heating factor besides the heating of the bolt caused by braking. To explore carefully, it is necessary to analyze the stress of automotive bolts.
Under normal conditions, the nuts and bolts auto mainly bear the gravity of automobile and load. This force is perpendicular to the direction of the black nuts and bolt (of course, there is also a reaction force with the same size and the opposite direction is the supporting force of the wheel hub). The magnitude of this force will change with the ups and downs of the car during driving. At the same time, the tire bolt of the car also bears the front and rear forces. When the car is moving forward, the direction of this force is backward, and when the car is reversing, the direction of this force is forward and perpendicular to the heavy load force of the car, It changes with the size of driving resistance.
The truck tire bolt will cause tire blowout
If the car brakes suddenly or starts suddenly, the force will become very large. In addition, when the car is turning, the tire bolt will be subjected to a force to the left or right, etc. (these forces have corresponding reaction forces, which will not be explained here).
In short, the stress of tire bolts is relatively complex. It is precisely because of the generation of these forces that certain squeezing or stretching effects will be produced on the nuts and bolts auto , so that the iron atoms inside them will move with each other and generate heat. Of course, if the strength of our tire bolts is large enough, the model is correct, and the tightening torque of the bolts meets the requirements, these heat will not affect the safe driving of the car. In addition, the heat generated by braking will be emitted into the air with the driving of the car, so the tire bolts will not be too hot, and will not affect the driving safety of the car. However, if our car doesn't pay attention to inspection and maintenance in time, for example, there is a problem with the toe-in of the tire, the deformation of the tire, the camber of the front wheel and the kingpin inclination of the front wheel, or the torque of the bolt doesn't meet the requirements, it will cause the stress of the tire bolt to change and generate a lot of heat, which will cause the bolt temperature to be too high, and over time, it will cause the bolt to loosen, If it is serious, it will cause the heat decay of bolts, and even cause accidents. So our driver friends can't ignore the problem of hot tire bolts when driving. They should always check and find out the reasons, so as to really drive safely and happily.
