According to the “Shanxi Evening News†report, at noon on October 7, 2012, a traffic accident occurred in the Salt Lake area of ​​Yuncheng. A Dongfeng truck with sand and gravel hit a pair of mothers and children riding an electric car. Unfortunately, when rescue workers When they arrived, the mother who had been pressed under the wheel had already died and the boy was seriously injured. It is understood that this is also a truck brake failure. The traffic accidents that occurred in the 11th this year can be described in too numerous ways. According to statistics, in just 8 days, there have been 68,422 accidents, 2,473 injuries and 794 deaths, of which truck-induced accidents are extremely high. proportion. The frequent occurrence of truck accidents inevitably has its causes. According to statistics from the Traffic Management Bureau, in the analysis of the causes of accidents, illegal driving was the first priority. There were so many car accidents caused by unfamiliar drivers. Second, it was the mechanical breakdown of vehicles. In various vehicle failure statistics, Braking failures occupy a very high proportion. The braking system should be regarded as one of the most important devices of a car. Its advantages and disadvantages directly affect the lives and health of drivers and others. But how should frequent brake failures be contained or mitigated? On this issue, the truck may wish to draw lessons from the bus. In China, the installation of a retarder on a passenger car has become a rigid requirement, and the effect after installation of a retarder is obvious. The cause of the bus accident is extremely low due to brake failure. However, there are very few truck users installing retarders, partly because users are not aware of the effect of retarders; the most important reason is that the price of retarders is generally high, and for truck users who want to save costs, This has become awkward. But which of life safety and economic costs is more important? Obviously it is "human life." However, the promotion of retarder cannot rely on the conscious of truck users. This requires the government to introduce policies to promote this, so as to objectively reduce the probability of truck accidents. How does the retarder ensure truck safety? It is understood that trucks are particularly prone to brake failures when they are on long downhill slopes, and the use of retarders can effectively reduce the braking distance. According to the person in charge of Taylor Mali retarder, Taylor Malo retarder can effectively reduce the braking distance by 30%, effectively improving the braking performance of the vehicle, making the vehicle more secure. In EU countries, the vehicle’s insurance premium decreased by 5% after the vehicle was installed. The retarder also provides a solution to the problem of overheating the brake system. The eddy current retarder can use electromagnetism to convert the kinetic energy of the car into heat energy to dissipate it, so as to realize a device for deceleration and braking. The maximum braking torque is 3300NM. For the output speed point, the maximum torque can be reached at 30km/h, and the effective speed point is 10km/h. That is, when the vehicle speed reaches 10km/h, the retarder can play a system of more than 85%. The action has greatly solved the problem of brake overheating and ensured the safety of the vehicle. The promotion of truck retarders is a matter of no time, and its merits are in the present day, which will benefit the future.
