Lightweight is a major trend in the development of freight vehicles. From the situation of vehicle upgrading in recent years, various parts that can reduce the vehicle's dead weight are used more and more frequently, and airbag bridge is one of them. With the promotion of relevant laws and regulations and the support of its own advantages, the airbag bridge has gradually stepped out of the application limitations of passenger cars, passenger cars and small cars and started to march towards freight trailers.

However, the car owner who is used to the leaf spring inevitably thinks: Compared with the leaf spring, the air bag is light, and how much load can it bear? Will it break down easily? Today, Darong Axle will discuss with you.

Objectively speaking, the airbag bridge can be supported by policies, which is only one of the reasons why it conforms to the trend of lightweight. In addition, the airbag bridge can also lift the single axle or the whole vehicle. On the one hand, it can lift the single axle when the vehicle returns empty, reducing tire loss and saving fuel; On the other hand, the vehicle height can be reduced during loading and unloading, which is more conducive to operation.

In addition, the elastic coefficient of the air bag can be automatically adjusted to match the speed of the vehicle, improve the stability and driving comfort of the body, ensure the constant height of the cargo box, and fully protect goods and reduce the rate of cargo damage on poor road conditions. This is also the reason why many Lvtong owners choose airbag bridge.

Some people say that the advantages of installing airbag bridges on trucks are many, and the disadvantages are almost gone except for the high maintenance costs. To be realistic, this statement is not very objective. There are advantages and disadvantages in everything, but the perspective is different.

One of the disadvantages of the airbag bridge is that the purchase cost is high, which is not a little expensive compared with the traditional leaf spring; Secondly, as just mentioned, the maintenance cost in the later stage is high. After all, the structure is relatively complex, which is understandable; Then there is the bearing capacity. The airbag bridge is very sensitive to the tonnage of goods, so it is easy to meet the demand for standard load transportation of vehicles. However, once the overload occurs, especially when the overload reaches more than 10%, the airbag will be accelerated to damage, greatly affecting the service life of the airbag. If the airbag is damaged, the replacement cost is not cheap.

In general, the service life of a set of airbag bridges is about 3-5 years. In this range, they basically need to be replaced. If the service condition is particularly good, they can be used for about 5 years. If the daily driving conditions are poor or there are problems in use, the service life may also be discounted.

The airbag bridge is durable but not durable, mainly due to the following points:

1. Whether the working conditions are suitable. The air bag bridge is suitable for the transportation of goods such as Lvtong, flowers, electronic instruments, dangerous chemicals, fragile goods, etc. It can protect goods and improve transportation safety. The road condition is poor and it is not bad. At the same time, the loading capacity of these goods is generally not too high. If the air bag bridge is used, the weight of the vehicle can be reduced to a certain extent and more loading space can be provided.

However, if the car owner usually transports heavy goods, such as building materials, sand, concrete, wood, coal, etc., it is not appropriate to use the airbag bridge. Even if it is reluctantly used, I am afraid that the frequency of maintenance and replacement will be very high.

2. Daily usage habits. Do you usually run more on highways, national highways, provincial highways, or down roads or mountain roads? Is there any overload, overrun or overspeed? Do you usually check and adjust the airbag height? Is the air bag bridge often exposed to high temperature, sediment, gravel and other environments? Do you pay attention to the air leakage of the airbag? Is there grease on the rubber parts of airbag bridge? These are closely related to the service life of airbag bridge.

3. Manufacturing process. The quality of airbag bridge also directly affects its service life, whether it is material selection, design, processing or quality inspection. Car owners must choose airbag bridges produced by formal brands, such as Darong Airbag Bridge. They entered the market early, their product performance has been fully tested by the market, and their user reputation is good. They can be more comfortable with such products.

In addition, the airbag bridge is also divided into American style and European style. The American style airbag bridge adopts the "I-beam" design, which generally has smaller deadweight and tends to be lighter; The European air bag bridge uses a leaf spring type guide arm, which has a relatively high bearing capacity and is more adaptable to poor road conditions. Car owners can choose according to their actual operating conditions.
