Inquiry: Why truck users are deterred from retarder

Every time you see a car accident, see blood, and see the tragic picture that was hit, your heart will be cool. The "safety" alarm rings again and again... "Safe departure, safe return" becomes the greatest wish of every driver and family member. How to make traffic safer? In addition to the driver’s experience, car brake systems such as retarders are gradually being noticed by truck drivers. When the car is decelerating or down a long slope, the retarder is enabled to decelerate smoothly, avoiding wear and heat caused by the use of brakes. It has a good effect on the safe operation of the driver." However, according to the reporter's investigation, many drivers have learned that the retarder but the ultimate retarder is installed to escort it is relatively small. What is the reason why the truck user to the retarder? Deterred?

Technical obstacles

Modification technology lags behind. China's auto-refining industry started relatively late, and development is relatively slow. Therefore, the overall technical level of car modification has a large gap with foreign countries. The current status quo is that the real professionals are relatively scarce. Most of the domestic automobile conversions are based on changing and changing, changing the racing seats, adding a rear wing and other simple parts modification, and more often than not. Hand-made live. Once it comes to relatively high-tech conversion projects such as the transformation of automobile oil circuits, it can be said that few domestic companies have the courage to change this technology. Some users who tried to hold down the retarder truck had contacted the local conversion plant and discovered that the retrofitting technology was relatively backward. The retrofitting and installation of the retarder in the old car was not only inexperienced but also could not be achieved on a technical level, leaving users with no confidence in it. .

Retarders are out of step with truck demand. China's heavy trucks are generally overloaded, and the retarder is designed based on the rated load. Once the truck is overloaded, the retarder's role is reduced. For example, in some mountainous regions, the amount of cargo transported is relatively large. If the weight of a vehicle with a retarder is less than 55 tons, the effect of the retarder will be good, but over this figure, the vehicle's installation torque will be affected. "A truck with the intention to install a retarder told the author. At the same time, with the national "three super" limit, truck weight is the trend of truck development, and the weight of the retarder is very heavy, adding a ton to the truck The weight is very restrictive for areas that are overly strict.

According to the author's understanding, many truck users have already contacted the retarder manufacturers, but no retarders have been installed. The main reason is that it is very worried about the conversion technology; whether the vehicle running after the retarder is installed will be normal and very worrying. It is not clear that the operation of the retarder will be consistent with the operation of the vehicle, and the import retarder is not clear. The accessories are imported from France and are very worried about whether it will satisfy the Chinese market's transportation.

Cost barrier

Currently, retarders used in the market include eddy current retarders and hydraulic retarders. Retarders foreign brands are Taylor, Voith, domestic Fast. It is understood that the purchase of any brand retarder at a price of about 30,000 yuan does not include the conversion fee. If the retarder is installed at the time of ordering a new car, the cost can be reduced. The cost of retrofitting the retarder to an old car will be much higher.

A user in Kunming told the author that he knew that the retarder had a high degree of integrity on the vehicle and the brake pads of the tires. It was indeed very good for the driver who frequently walked down the mountain, but it was too expensive. In the past two years, shipping costs ranged from 430 yuan/tonne to 360 yuan/tonne, and with high-speed tolls rising, the net profit in one year is very small. It is also necessary to support the family's life. Be careful and reluctant to spend so much money. The survey found that the application groups of retarders are more concentrated in group users or large logistics companies. Although the motor vehicle operating standards implemented last year clearly stipulated that more than 12 tons of trucks, dangerous goods transport vehicles, and road buses with a length of more than 9 meters, tourist buses will be forced to install retarders or other auxiliary braking devices. However, with the high cost of logistics transportation in our country, many logistics companies are also cutting expenditure and increasing expenditure. Although they understand the value of retarders, they are more careful in the face of additional expenses.

How can fish and paws double up? Truck users can either install retarders or invest in such risks. Although retarder manufacturers and vehicle companies have begun cooperation, the current results have not seen much improvement. I would like to think whether the retarder manufacturers can provide users with a more comprehensive understanding of the product. Can they add support for technical modification? Retarder manufacturers can be reduced in price, so that more truck users can have the ability to install retarders with ease, allowing trucks to move toward a safer itinerary.
