According to on-site sources, the new GB7258 standard will be officially promulgated at the end of 2011. As for the brake system-retarder chapter, the state regulations will be implemented on a 24-month transition period from the date when the regulations are officially promulgated.
At the seminar site, representatives of truck companies have endorsed this, believing that the implementation of this regulation will bring higher safety protection to domestic trucks, while some companies previously installed retarders, which caused cost pressures or other truck companies. Concerns about expanding brand influence were also resolved by the promulgation of standards.
As a Telema retarder with a long history of more than 100 years, it is also pleased with the new regulations on retarders in GB7258, which believes that it can provide safe and stable operation for truck users in China, and also hopes to advance Teloma Technology brings truck users in China to work together for safe truck braking.
According to the reporter, European countries have already begun to install retarders for passenger cars and trucks with more than 8 tons in the 1950s. It also emphasizes that EU members must follow such regulations. But this is only a low limit. Some countries have adopted stricter national regulations due to historical reasons and specific geographical environments and road conditions.
However, the Ministry of Communications of China issued the JT / T325 "Classification and Rating of Operating Passenger Cars" standard in 1997. Only when it was revised in 2002, it was stipulated that large and medium-sized high-secondary and high-third-level operating highway buses must be installed with a These regulations, although later than foreign regulations, have played a positive role in the development of China's retarder industry and the safety of vehicle driving.
The so-called vehicle retarder is a vehicle auxiliary braking device whose maximum function is to enhance the safety of vehicle braking: the retarder can bear 30% -80% of the braking energy required when the vehicle is decelerated; Brake failure caused by excessive brake temperature; or tire puncture caused by excessive friction.
