Large trucks, tires and wheel heating, and can not find out the problem, the general heat to the number of temperature, tires or wheels will be dangerous situation?
Brake drum burning: brake may not return or drum phenomenonThe brake drum is the commonly known as "pot" thermometer, as long as the brakes, it will be fever, is the largest local heat front. While the brake drum temperature is related to environmental temperature, speed, braking frequency, the weight of the car and the road, step on the brakes, 100-200 degrees are, even heavy truck can reach 300 degrees above in the downhill.
The hub (shaft head) is hot: it may be tight or abnormal wearThe hub is in the inside of the brake drum, which is the axle head that is installed when it is disassembled. The hub (shaft) is hot, usually bearing assembly too tight or lubrication is not good, the temperature is too high will lead to the inside of the grease melt, flow out, affect the brake effect, will burn the bearings seriously. If the shaft is hot, be careful. It may be that the bearings are tight or abnormally worn.
Usually the hub heating, resulting in heating tires, all cars brake drum will be hot. The faster the car, the greater the weight, the higher the degree of thermal brake, which is the principle of energy exchange. If the wheel heating abnormal, it is recommended to check in time, troubleshooting.There are two possibilities for the front wheel hub to burn, one is the wheel hub (the axle head), and the other is caused by the heat of the brake drum.
