On September 29, 2017, with the release of GB7258-2017, it had a significant impact on the truck industry. GB7258 is an important part of my country’s national motor vehicle safety technical standards. It is the most basic technical standard for vehicle operation safety management and accident vehicle inspections such as registration inspection, in-use motor vehicle inspection, motor vehicle inspection, etc. It is also the most basic technical standard for motor vehicle inspection in my country. One of the important technical basis for new car type mandatory inspection, new car factory inspection and imported motor vehicle inspection.

Like GB1589-2016, this time GB7258-2017 is also aggressive. More stringent safety indicators have prompted our manufacturers to improve their technical level.

Article 11.10.1 of GB7258 requires trucks with a total mass of more than 7500kg and special operating vehicles modified with truck chassis shall be equipped with anti-splash systems, and all wheels of other motor vehicles shall have mudguards. This means that our existing products: self-unloading, mixing, and semi-trailer all need to be equipped with anti-splash systems. So what is a splash system? What are the technical requirements for the anti-splash system? How can we design and manufacture to meet the requirements of the standard?

Next, let’s get to know the anti-splash system together:

Friends who have been on a high speed on a rainy day may have seen that the truck is racing in front, and a lot of water mist is generated around the tires of the vehicle, which reduces the visibility of the rear vehicle, affects the line of sight, and poses a very big safety hazard. The anti-splash system required to be installed in the standard is aimed at this problem and reduces the generation of water mist through the energy absorption device and the water vapor separation device of the fender.

The performance requirements and measurement methods of anti-splash systems for automobiles and trailers (GB 34659-2017) give a detailed description of the anti-splash system. The anti-splash system is equipped with anti-splash devices (including air/water separation devices and energy absorption devices). ) Composed of mudguards, outer baffles and rain curtains. The anti-splash system is equipped with an anti-splash device to meet the standard requirements, and it is not necessary to add both devices.
