Retarder installed why a suspended

80% foreign heavy truck equipped with retarder, the developed countries in Europe and America in the early 50's of the last century has asked more than 8 tons of truck mandatory installation of retarder retarder, at present has become the standard configuration of many developed countries in Europe and America buses, tourist buses, medium and heavy duty truck. Why in our country, but also from the wagon retarder so far? The Yangcheng Evening News reporter interviewed industry stakeholders.

The law does not mandatory norms

People in the industry generally pointed out that, due to our truck with retarder retarding devices such as not clearly defined, it becomes difficult to use the important reason retarder on wagon.

"Because there is no mandatory provisions, the earliest time retarder popularization and application is very difficult," Shenzhen teerjia Limited by Share Ltd chairman Zhang Huimin told reporters. He said, retarder while in foreign countries has been in use for fifty or sixty years, but only began around 2000 Chinese import market. "At that time, no one knows what is it. Technical personnel carrying equipment, daily run bus company, after a lot of persuasion, please free installation experience."

UBS Securities analyst said the city bus, grading technical requirements and relevant regulations of our country allocation of retarder industry only in 2002 the Ministry of Construction issued "" (CJ/T162-2002) and the Ministry of communications in 2006 issued the "operating passenger car type classification and rating" (JT/T325-2006). These two rules separately to the higher level of the large and medium-sized bus mounted retarder made non mandatory requirements. But for large trucks do not require.

The personage inside course of study says, China's auto industry on the safe operation of motor vehicles of the most important aspects of the standard GB7258 "the safe operation of motor vehicle technical condition". However, according to the reporter consulted, the current GB7258-2004 released in 2004. This version of the regulations on the braking distance and vehicle emergency braking and parking braking condition reducing speed and braking force distribution, but for the retarder is mainly to solve the "braking" no relevant provisions.
