Within the secondary suspension between the bogie and the vehicle body, our air spring systems provide for the flexible mounting of the vehicle body. Air springs have a low natural frequency, which minimizes the transmission of vibrations. They decouple it from the majority of track irregularities, while also allowing the bogie to turn as the train negotiates bends.
An outstanding feature of the system is its combined air spring and integrated rubber-metal auxiliary spring. Using this technology, we can develop system configurations for a wide variety of bogies and vehicle body models.

Extra-high lateral deformability makes half bellows ideal for use in bolsterless bogies, including those used for high-speed trains, and in state-of-the-art bogies for local and Metro trains.
Rolling lobe air springs are used in extremely confined spaces in trams and low-floor bogies.
Belted air springs allow for increased load-bearing capacity in bolstered bogies when compared with conventional bellows.
Double convoluted air springs are the simplest solution from a technical point of view for air-suspended secondary springs. They are characterized by a high degree of reliability, and can perform large stroke movements.
Together with the air spring, auxiliary springs form an essential part of the secondary suspension.
The external guide provides for a greater load-bearing capacity when compared with unguided springs. The spring is effectively protected against external influences, such as vandalism.
