Is it a trend for trailer air suspension to match disc trailer axles?
From the current trailer development history, China's road transport industry has gone through the previous savage development stage, into a new development process, you can look at the advantages of air bag suspension and disc trailer axle, to analyze what the development trend of China's trailer is.
At present, the trailer in developed countries is basically airbag suspension + disc brake trailer axle, mainly because the safety has been greatly improved, air bag suspension can not only protect the chassis or effectively reduce the damage to the overall frame of the trailer.
At present, the new national standard GB7258-2017 mandatory installation of air suspension and disc trailer axles for three-axle pallet trucks and warehouse grid semi-trailers shows that the country really wants to govern the freight industry, three-axle pallet trucks and warehouse grid semi-trailers account for more than 50% of domestic production of trailers, basically in addition to some special purpose vehicles. Other goods three axis pallet car and warehouse grid basically can meet the needs.
Lightweight airbag suspension with adjustable height:
1, air bag suspension in popular terms, is to replace the common steel plate with air bags. A sealed gas tank is filled with compressed air, which takes advantage of the compressibility and elasticity of the gas to achieve shock absorption of the vehicle. You can think of it as a ball, and we can squeeze it hard, and we can inflate and deflate it, and it can withstand tons of pressure.
2, high comfort, good shock absorption effect: air bag suspension uses compressed air to achieve soft connection. It can alleviate most of the impact from the road surface, reduce the turbulence when the road is too bad, not only the driving experience is comfortable, but also the protection of the goods is also very strong, especially high value-added items, such as precision instruments, express delivery, tank trucks, cold chain transportation, etc., to avoid damage caused by turbulence.
3, lighter weight: Now the new national standard has been implemented, only legitimate and compliant trailers can go further. After the rated load is calibrated according to the axle, lightweight is what the major manufacturers have to do. The air bag suspension is definitely lighter than the steel plate suspension, and a set of air suspension is at least more than 100 kilograms lighter than the steel plate suspension, which can effectively increase the weight of the goods.
At present, the disc brake trailer axle + air suspension system launched by DARO trailer axle is very comfortable, suitable for road transportation, not only can protect the chassis system and tires of the trailer, but also the service life of other parts on the trailer with the air suspension system will be correspondingly extended.
In the long run, the use cost of the trailer is similar to the previous plate suspension and drum brake system, so now the country slowly eliminated the drum brake under the premise of ensuring safety, and now it is only a three-axis fence truck and warehouse fence trailer, which may cover other trailer models in the later stage.
