The air suspension in modern chassis is a combination of finely tuned assemblies: the air spring bellows and the rubber-metal bearer spring, which supports the system especially when there is torsional strain and large horizontal excursions. It also absorbs a portion of the vertical deflection and reacts as an emergency spring.
Benefits & features
ContiTech and Phoenix air spring systems play a key role in the secondary suspension. It's all a matter of the air: air springs have a low natural frequency, which minimizes the transmission of vibrations.
An outstanding feature of the system is the combination of the rubber-metal auxiliary spring integrated in the air spring. Using this technology, we can develop system configurations for a wide variety of bogies and vehicle body models.
- Increase in ride comfort thanks to pneumatic suspension irrespective of the load conditions
- Reduction in structure-borne noise transmission from the bogie to the carbody
- Adjustment of the vehicle height at different loads
- Stabilisation of running dynamics
- With a constant, adjustable height, the railcar body can maintain an ideal distance from the platform
- Passengers can board and disembark the vehicle safely and comfortably
Reliability in the original
We supply exclusively original spare parts with identical qualities to the first generation of products. Also for customer-specific solutions.
Thanks to a global network of dealers, qualified, in-house technicians, and experienced assemblers, our products are available on short notice anywhere in the world and are exchanged reliably.
Above all, our exemplary set of measures ensures that customers' spare parts and maintenance needs are predictable in the long term. With competent consultation, preventative inspections of used parts, precise laboratory measurements and early needs assessment, we offer you the security of preparing maintenance and replacement work more than twelve months in advance, in a systematic and thus cost-optimized manner.
Another advantage: We generally only provide complete suspension kits that contain all truck suspension components. This eases the logistics for our customers in the long term and guarantees that no components are missing.
