Correct interpretation of GB 7258 regulations on retarder or other auxiliary brake device

“Technical Conditions for Operational Safety of Motor Vehicles” The requirements of the brake system for vehicles set out in the new standard of the Regulations of the People's Republic of China (GB7258) proposes that trucks and dangerous goods transport vehicles with more than 12 tons will be forced to install retarders or other auxiliary braking devices. The China Truck Network reporter had already reflected in the article “The truck brake safety has taken a big step toward the international standard and the new standard of GB7258 emphasizes the mandatory installation of retarder”. However, during the reporter's visit, it was found that most people misunderstood the laws and regulations and thought that as long as the retarder or other auxiliary braking device was installed in this type of vehicle, it would surely meet the braking requirements in the regulations. However, at this time, we ignored the interpretation of “vehicle braking”. Actually, in the regulation of Regulation GB12676 , the vehicle brake has been explained in detail. In this regard, China Truck Network gives you a correct interpretation.

Does the other auxiliary brake device meet the braking requirements?

The China Truck Network reporter learned from industry experts that in the requirements of IIA test of GB12676 regulations, the following provisions have been made for truck brakes (experts want to make readers more readable, with special examples), and trucks with full load are on a 6% downhill slope. Instead of using the main brake system of the vehicle, only the auxiliary braking system is used. The truck should be able to descend at a steady speed of 30 km/h for 12 minutes. Experts told reporters that this rule determines that the truck brakes must meet the requirements. Only trucks equipped with retarders can be completed. The installation of other non-retarder auxiliary braking devices alone cannot meet the requirements of the regulation.

Retarder companies are actively preparing

As the representative of the eddy current retarder, Talima acknowledged the interpretation of the policy. Wang Xiaobin, the manager of the technical department of Talmar Brake System Co., Ltd., told the reporter that based on the good situation, the company also installed a retarder on the truck. The series matching and matching experiment hopes to get the user's approval quickly after entering the market. In spite of this, Wang Xiaobin also mentioned that there are still problems with the domestic truck-mounted retarder, such as user perception, price, and installation issues.

In terms of installation, Wang Xiaobin believes that the installation of a retarder before the new car leaves the factory is currently the best choice because the new car can be set aside to install the retarder at the time of design, and the design before leaving the factory will not affect Cost, and for the old car, because of the conversion, matching and cost increase the user's cost;

In terms of users’ perceptions, Wang Xiaobin stated that Tailemar will seize the opportunities of rare regulations to cultivate markets and carry out marketing activities so that users can truly understand the retarder and recognize the performance and characteristics of the product, especially the retarder. The sustainable economy brought about by the use of vehicles.

CNC feeding worktable can be divided into fixed part and movable part. The fixed part is set on the ground which is linked with main unit. To the fixed part, alongside the front-back direction of main unit is called Axis Y, and then the fixed part is called Axis Y rack. The movable part is installed on the Axis Y rack through the guide bush which is rolling in straight line, under the driven by the servo motor and ball screw shaft, the movable part is running though the Axis Y to realize precise positioning. To the movable part, alongside the left-right direction of main engine is called Axis X, and then the movable part is called Axis X rack. Axis X rack is closed to the head of the main engine, on both sides which is installed a supporting plate with universal transmission ball to support the work piece. At the back of the Axis X rack, two rolling guide bushes are installed with a sliding plate on the direction of Axis X. Under the driven by the servo motor and ball screw shaft, the sliding plate can running though the Axis X to realize precise positioning.
