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.

Half bellows for bolster-less bogies enable vast lateral deformation. For high-speed trains and modern bogies in local and metro transportation.
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 l...
Rolling lobe air springs are used in extremely confined spaces in tram bogies and low-floor bogies.
Rolling Rubber Spring for primary and secondary suspension.
Enable high lateral deflections in combination with air springs in secondary suspensions.
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.
