Recently, major media have continuously disclosed investigation results to the “most beautiful driver caseâ€. Many media have made such reports: “The most beautiful driver case†is the brake drum on the east windmill emerged, causing injuries and causing Wu Bin to bus driver. According to the reporter's further understanding, it was found that “the brake drum was detached from the Dongfeng truck†and it was actually a misreading. The brake drum that was detached was actually the brake drum on the trailer behind the Dongfeng tractor.
Those who understand logistics transportation know that the whole vehicle of a tractor is composed of a tractor head and a trailer. The trailer is towed by a traction head. Generally, the tractor and the trailer are produced by different manufacturers, and they are licensed separately. Vehicle insurance is handled separately. A tractor can be equipped with a vehicle. With different trailers, the “splashing and transportation†promoted by the government in the past has been to promote the use of multiple tractors for one tractor.
According to the reporter’s further understanding, in the “Wu Bin caseâ€, the brake drum that hit Wu Bin came from the brake drum on the second row of wheels in the three-row wheel of the trailer in the rear half of the whole tractor vehicle. Car front. As the front of the tractor is the Dongfeng brand, many media misunderstood the iron block as the "Dongfeng truck brake drum."
In fact, compared to disc brakes, drum brakes commonly used in trucks in China do have a tendency to heat up after long brakes. In addition, vehicles frequently use brakes under overload or overspeed conditions, or adjust brake air pressure without permission, install shower devices, or perform regular inspections of brake drums in accordance with product instructions, and use inferior or counterfeit brake drums. Brake drum cracking can easily occur. In recent years, various accidents caused by the failure of brakes in China's trucks have emerged in an endless stream.
From a safety point of view, the use of disc brakes by trucks has gained consensus in the industry. Many vehicle companies are also promoting disc brakes. Now, many brand tractors have been equipped with disc brakes, and the trailer is still mostly drum brakes. In addition, many trailers are produced by small factories, parts lack a strict quality management system, and some trucks are heavily overloaded, which makes the brake drums of some truck trailers a potential killer.
Of course we need to praise heroes such as Wu Bin, but we need to pay more attention to the safety of trucks. We hope that Wu Bin’s case will become less and less, and hope that “flying things out of the sky†will not appear again.
