Secondary Suspension

Secondary Suspension

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.

These products are not available in South America.

Benefits & Features

• Increase in ride comfort thanks to pneumatic suspension, regardless of the load conditions
• Reduction in structure-borne noise transmission from the bogie to the vehicle body
• Adjustment of the vehicle height with varying loads
• Stabilization of running dynamics
• Thanks to its 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 Guaranteed by Original Parts

We exclusively supply spare parts with identical qualities to the equipment originally installed. Thanks to our global network of dealers, qualified in-house technicians, and experienced assemblers, our products are available at short notice anywhere in the world and are replaced in a reliable manner.

Thanks to our competent consultations, preventative inspections of used parts, precise laboratory measurements and early needs assessments, we are able to offer you the security of preparing maintenance and replacement work more than twelve months in advance, in a systematic and therefore cost-optimized manner.

We generally only provide complete suspension kits that contain all the components for the bogie suspension. This eases the logistics for our customers in the long term and guarantees functional complete solutions.
