Six years ago, airbag suspension began to enter the field of vision of ordinary users. Since then, airbag suspension has gradually appeared on domestic high-end models, including main vehicles and trailers, with high prices and superior performance. Airbag suspension was once promoted to the "sacred altar" by truck enthusiasts. ?
Excellent shock absorption effect? ??Reduce cargo damage rate
So who were the first to use airbag suspension? In the early days, customers who could afford airbag suspensions were usually wealthy people, such as tobacco groups and precision instrument manufacturing companies, who were not short of money. After all, in the early days, the main cars and cars equipped with airbag suspensions The price of buying a trailer is at least a million dollars.
Why do you spend a lot of money to buy a car with airbag suspension? This is still related to the characteristics of the air bag suspension. The airbag suspension uses air springs as elastic elements and air as the elastic medium. Compressed air is filled in a sealed container, using the compressibility of the gas and elasticity to achieve shock absorption on the vehicle. To put it simply, it is just like the rubber ball we usually play. The process of pressing the ball hard is the process of the airbag suspension working.
This also makes the airbag suspension have an unparalleled shock-absorbing effect that other suspensions have, and good shock-absorbing effects can reduce the chance of damage to goods, especially in the transportation business of such high value-added goods. Once cargo damage occurs, the loss can easily exceed the value of the vehicle.
At the same time, the airbag suspension can also minimize the vibration of the vehicle from the road and minimize the damage to chassis components due to vibration. This can avoid the loosening of the screws of various components on the chassis and improve safety. . This is why you should buy airbag suspension even if you spend a lot of money.
Systematization increases vehicle weight and cargo capacity
In 2016, airbag suspension ushered in great growth. Due to the promulgation of GB1589-2016 at that time, the total weight of tractors, trucks and other models was reduced. The total weight of 6X4 six-axle tractors was reduced by 6 tons, and the total weight of 6X2 six-axle tractors was reduced by 9 tons.... Some are forward-looking Sexual users are beginning to look for lightweight products.
Lightweight is a system that needs to be optimized from the entire vehicle to its components. Airbag suspension also relies on diverse combinations, such as solutions with disc brakes and large single tires. User choice, taking BPW's airbag suspension as an example. If a six-axle tractor uses airbag suspension with disc brakes and large single tires throughout the vehicle, it can achieve a weight reduction of 1.5 tons. Taking the cheapest goods on the market at 200 yuan/ton, if you make 10 trips per month, you can earn more than 30,000 yuan more than ordinary steel plate suspension models in that year.
At that time, many people thought that the purchase cost of airbag suspension was too expensive, so they had no choice. Only some people with long-term vision chose airbag suspension. Facts have proved that the extra freight earned has already made up for the purchase. fee.
The policy has been clarified? There are more than a few advantages
With the development of airbag suspension to this day, many advantages have been verified by the market. And according to the requirements of GB7258-2017, starting from January 1, 2020, the rear axles of dangerous goods transport trucks with a total mass of 12,000kg or more, all dangerous goods transport semi-trailers, and three-axle fence type and warehouse gate semi-trailers shall Equipped with air suspension. Now that national policies have begun to promote airbag suspension, it is enough to prove that the advantages of airbag suspension are far beyond our imagination.
In addition to the advantages of light weight and good shock absorption effect mentioned above, the airbag suspension also has strong road adaptability and ultra-high cargo matching. Simply put, the airbag suspension The rack can run on almost any road and can carry all kinds of goods.
At the same time, if the whole vehicle uses a combination of air bags + disc brakes, then the main vehicle and the trailer will make a "squatting" deceleration action when using the brakes, which is detrimental to the braking system and extending tire life. All are very helpful. According to BPW Axle statistics, using airbag suspension + disc brakes can extend the service life of tires and brakes by 6%. These are the hidden costs of the vehicle, which will amount to a considerable expense over the long term.
Air bag suspension will definitely show explosive growth in the future. People who used air bag suspension in the early and mid-term have already realized its advantages and enjoyed the benefits it brings.
With the implementation of policies, airbag suspension will become the mainstream configuration in the future. Only when airbag suspension is fully popularized can more people enjoy the "dividends" of airbag suspension!
