Air Springs – Vibracoustic SE

From the minimum loads of an unhitched tractor to the weight of a fully-loaded trailer, commercial vehicle axles need to cover extreme load fluctuations with the rear axles being exposed to the main load of those fluctuations. With their ability to quickly change the spring rate according to the current load situation, commercial vehicle air springs are an excellent solution for this challenge. Therefore, they are used in most commercial vehicles like trucks and buses as well as in trailers.

Commercial vehicle air springs from Vibracoustic CV Air Springs offer an excellent combination of reliability, safety, and comfort for trucks, tractors, trailers and buses. By adding or releasing air, the same level of driving comfort can be provided and a constant height can be maintained for all load situations.

Keeping the vehicle and trailer at a constant height level maintains vehicle stability and provides safe driving characteristics. Furthermore, it improves vibration damping in all load conditions. This reduces axle, transmission and tire wear and increases vehicle durability and efficiency. In addition, the truck suspension cannot bottom out thanks to the air springs and the chassis and the transported goods are strongly protected from damage.

The driver as well benefits from improved vibration damping, which provides high driving comfort and reduces driver fatigue for a relaxed and secure haulage.

Air Springs with Cross-Ply Bellows - Vibracoustic

The cross-ply bellows uses two layers of reinforcement fibers. These are placed in the bellows wall at an angle to each other and define the pressure resilience. The layers are coated from both sides with a sealing or protective elastomer layer. Another elastomer layer, the intermediate layer, is applied between the two layers of threads. The intermediate layer defines the geometrical cohesion of the two layers of threads, and thus influences service life and comfort. A steel reinforced crimp area ensures the bellows has a secure and air-tight fit. Cross-ply bellows can be combined with plastic top pots and pistons for a lightweight design.
