At 1:10 a.m. yesterday, a large truck caught fire near the West Exit of Quzhou, Hangzhou-Jinhua-Quzhou Expressway. Zhou Jianguang, a police officer of the high-speed traffic police dezhou detachment, said that during the fight, the right rear wheel exploded and one person suffered a fracture of his right hand.
As the outer packaging of the freezer is made of foam plastic and cardboard boxes, the fire spread rapidly after the fire broke out, and a large amount of smoke emerged. The sandwich inside the freezer was still smoldering.
The first two fire engines that had arrived had used up all the water and had not yet managed to control the fire. Later, three fire trucks were dispatched to reinforce the fire.
Post analysis
Afterwards, the driver Yang said he set off from Ningbo, and when he drove to the Ganzhou section, he smelled a burnt smell. He quickly got out of the car and saw the smoke in the right rear wheel. He took the fire extinguisher from the cab. Just ten minutes after the extinguishing of the open flame, he began to burn again. In desperation, he only had an alarm.
Yang said that this fire was the hub of the right rear wheel (the metal part in the middle of the tire) and it only ignited the tire.
special reminder
Chen Tao, manager of Zhejiang Jiangling Motors Service Co., Ltd., said that the car has been in service for a long time, and the brakes have been used for a long time. The wheels are prone to heat. In addition, the friction between the tire itself and the ground also generates heat. In general, large trucks have a spray water cooling system to prevent hub heating. This fire is likely related to the failure of the spray water cooling system.
The average person who is out of the car often inspects the tank, the oil circuit, the circuit, and the surface of the tire. It is easy to overlook the wheel hub. In fact, when the tires are used for a long time, the hubs will wear more severely, especially for those vehicles that are overloaded with long-term overload, the wheels are more likely to wear, and the cooling system may also malfunction.
Because the hub structure is concealed, it is difficult for the driver to discover the problem. The precautionary measure is that, after driving about 5,000 kilometers, he should regularly go to a professional repair shop to do inspection and maintenance.
