In recent years, the traffic accidents caused by punctures and failures of heavy trucks due to overheating of brakes have been increasing year by year. Therefore, the deployment of retarders for heavy vehicles is increasing. Previously, due to factors such as cognition and price, the promotion of retarder on trucks has been difficult. In the past few years, has the heavy truck user's awareness and concern about the retarder changed?
Increased user attention
In Europe, retarders or other auxiliary braking devices have long been regarded as routine equipment, not only because of the promotion of policies and regulations, but also because users have realized that the total cost of use of assembled retarder vehicles is much lower than that of unassembled vehicles. After investigating multiple truck users, the reporter found that some domestic users are beginning to realize the importance of retarders and are no longer simply concerned about the relatively high prices of retarders.
The truck driver named Westwind is a user who dares to "early adopt". He has been in touch with the retarder since 2005. Through years of in-depth research, he will now install it as soon as he updates the vehicle. According to him, installing a retarder is a safety measure. “I always use Chengdu as a starting point. No matter where I go, I have to go through the mountain. It is precisely because there are many ups and downs in the area. The demand for vehicle braking performance is high."
"West Wind" pointed out that the current domestic heavy-duty truck's braking performance is not sufficient to meet the complex mountain conditions, so the water shower is currently the most common way to deal with the lack of braking. However, even if a shower device is used to cool the brake drum, the expected braking effect cannot be fully guaranteed. After a long time downhill, the truck brake distance will be longer. In case of an emergency, the consequences will be unthinkable. “There are more and more cars on the highway, and traffic jams are very serious. In the event of a downhill car, it is just a traffic jam. Because of the short braking distance, a traffic accident is likely to occur. I personally witnessed a dangerous goods transport. Because the brakes were not enough, the car caught fire with the rear-end vehicle. The fire was said to have burned for three days and three nights.†“West Wind†said with an oversight.
In fact, the "West Wind" car also encountered insufficient braking before installing the retarder. He recalled that every time a car goes downhill it will be scared for a while. With the retarder installed, the braking effect of the vehicle is improved significantly, the number of showering is less, and the road is more time-saving. The most important thing is that when the user goes downhill, his heart is also “more bottomedâ€.
Although still not enough awareness <br> <br> attention begins to lift, but users will eventually install retarder is relatively small, the reason is product awareness is still not enough.
The “crows†of truck driver netizens from Sichuan are experts in the study of retarders. Due to their reputation, many users visit and consult. He believes that the retarder is a very important part of the vehicle. The reason why it has not yet been popularized is that everyone does not know enough about the retarder.
“When the vehicle is downhill, the overheating of the brake pads will cause problems such as brake failure. Therefore, it is very important to install a retarder. Not only that, but many owners think that running in a flat terrain can be done without a retarder. This is a misunderstanding. In fact, braking through a retarder on a flat road can make the car brakes softer and decelerate more smoothly, and it can reduce the loss of the main brake," said Raven.
Not only does the user not know enough about the retarder, many vehicle companies do not have enough knowledge of the retarder. There is a truck driver who knows the technology and is well-known in the truck driver circle. Even the technicians of the car company find him asking about the installation and use of the retarder.
Now through the "Crow" recommendation, many users around the world have gradually learned about the retarder. However, “West Wind†believes that the retarder is still a new thing for Chinese truck users. Cognition needs a process, but it will develop very well in the future.
Vehicle matching problems to be solved <br> <br> retarder in addition to lack of awareness, the "crows" that the matching between the retarder and the vehicle is also problematic. If you want to effectively promote, you need to do a lot of work for OEMs, engine companies, and retarder manufacturers.
“Retarders are not standard at the time of delivery of domestic cars, and users will have to install them on their own.†“Raven†pointed out that after installing the retarder, because it needs to disperse a large amount of heat for a short period of time, the vehicle needs to be added. Large water tanks, increased cold water, and increased water flow rate of the pumps, many of these car companies did not consider them when designing products, and they would not leave any room for installation.
Therefore, vehicles that install retarders on their own generally have problems such as large instantaneous temperature difference of the retarder and vaporization of coolant at a local high temperature. Moreover, almost no car company in China can provide pre-sales and post-sales training on the use of retarder, resulting in the user being unable to correctly judge the problem of the retarder. In addition, the problem that the retarder cannot be effectively compatible with GPS is also a problem.
"Because of these problems, many users who installed the retarder have later dismantled themselves." "Raven" said that he had communicated with some of the car's technical personnel, hoping they would do more matching experiments with the retarder. Can be rectified as soon as possible.
Some people in the industry also believe that the reason why the retarder has not been promoted, the higher purchase cost is only one of the reasons, the greater obstacle is the car company's non-cooperation.
"Now, many large-scale logistics companies are not bad. They buy imported vehicles that are fitted with retarders, and the prices they purchase will far exceed those of domestic products. Imported vehicles, even if they are not equipped with retarders at the factory, are The design also makes it easy to install a retarder,†said the person in the industry. If domestic car companies formulate matching strategies and allow users to use well, I believe most users are willing to use retarders.
A good sign is that some manufacturers now have retarders installed at the time of delivery of their vehicles, such as some of Shaanxi Automobile Delong, Dongfeng New Tianlong, and high-end heavy trucks using heavy-duty trucks.
When it comes to Electric Bicycle Display , I believe everyone is familiar with them. They are a visual expression of the bicycle's state to the cyclist. Currently, bicycle Bicycle come in black and white screen and color screen designs, and their sizes vary depending on your personal aesthetic and choice. Through the instrument panel of an Electric Power Assisted Bicycle, you can intuitively understand the speed and distance you have ridden. You can also see whether the Lithium Battery is fully charged or not through it. After the battery is fully charged, the instrument panel will also display whether the battery is charging or fully charged. More intelligent and technologically advanced than regular bicycles without added bicycle gauges. If you like simple and elegant, choose a black and white LCD screen. If you like cool technology, choose a color TFT screen. In terms of cost, of course, the price of color TFT screens is slightly higher than that of black and white LCD screens. Would you mind or not about the cost.
