The air suspension was born in the middle of the nineteenth century, and it went through the development process of pneumatic springs, airbag composite suspensions, semi-active air suspensions, and central inflatable suspensions.
By the 1950s, air suspensions had matured. Began to be applied in passenger cars, trucks, buses and railway cars. In some developed countries, especially in Europe and the United States, the application proportion of air suspension on trucks and semi-trailers has reached more than 95%.
Whether in Europe or North America, the air suspension cannot open the airbag structure, but due to differences in road conditions and load requirements, the air suspensions they use are not exactly the same. At present, the domestic air suspension is mainly based on these two types.
American air suspension features
The guide arm is welded by multiple steel plates, and generally has the design of “I-beam”. The weight of the guide arm will be relatively light.
The contact area between the guide arm and the axle of the American air suspension is larger, and the lateral support performance of the vehicle will be better. However, due to the relatively short stroke of the airbag, it is more suitable for use under better road conditions.
Features of European air suspension
The guide arm of European-style air suspension (also called German-style air suspension) is more like a traditional leaf spring structure. It is generally one-piece or multi-piece, directly forged, and has better load-bearing performance.
Because the shape of the guide arm can be bent, the stroke of the airbag is relatively longer and the shock absorption performance is better. In addition, the leaf spring guide arm itself also has good shock filtering performance and is more adaptable to road conditions. Some.
For countries with relatively complex road conditions, the transportation is also biased towards heavy loads, so there are relatively more applications for European-style air suspension.
Panda mech’s air suspension is built with new technology, strong toughness, good sealing, can calmly deal with the impact of bumpy roads on the frame, reduce load and stress, classic European design, long service life, high bearing strength, Equipped with Darong disc axle, the accuracy, dead weight, rigidity, wear resistance, bearing capacity, fatigue resistance, etc. are fully up to standard, which can effectively reduce cargo loss and improve operational efficiency.
