On the National Day in 2012, the 28-year-old Tang Pan experienced great joy in his life. On October 3, the wife was only picked up, but when the bride returned to the gate on October 4, a truck that had lost control of the brakes caused him to lose his new wife. However, tragedy is not an example. According to statistics, in just 8 days, there have been 68,422 accidents, 2,473 injuries and 794 deaths, of which truck-induced accidents account for a very high percentage.
The eight-day long vacation should have been reunited or relaxed, but so many tragedies have occurred. It is heartbreaking but also provocative. What are the reasons for the accident?
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 failure of the brake caused serious damage to the truck accident. It was a pain to people's casualties. Solving the brake failure is not an ineffective solution. Adding a retarder device to solve the brake failure on the existing brake system is a line The effective way.
It is understood that in the domestic truck industry, retarder is still in the promotion stage. The author learned from Talloman Retarder Co., Ltd. that Tellomar retarder is used in foreign brands such as Renault, Mercedes-Benz, Volvo, and Scania. All of them have been widely used, but in China's truck market, retarders are beginning to emerge.
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.
Automotive retarder is the product of China’s entry into the market in the 1990s. With the introduction of China’s relevant policies and regulations on automobile retarder since the late 1990s, China’s automobile retarder industry has also achieved rapid development. Vehicle retarder, as an auxiliary brake device, is influenced by domestic policies. After several years of rapid development, the development of China's automobile retarder industry is at a critical stage. At present, the retarder is widely used in passenger cars, but it is still not a lot in trucks and it is in a cognitive stage. However, the current high-speed truck accidents have made the use of retarders more urgent. It is believed that trucks equipped with retarders will become a hard requirement in the near future.
