Air Springs for railcars
The railway industry requires robust and reliable anti-vibration solutions, and Larosi’s air springs, often associated with the Torpress Springhel brands Firestone, Continental, Saga and Pirelli, meet these high standards.

Progressive stability:
Progressive force/displacement characteristics ensure stability under varying loads, an advantage for trains with different passenger or freight weights.
Saga Springhel and Pirelli air springs for railways
Torpress Springhel Firestone Continental, Saga and Pirelli springs are designed for “modern rail technology” and are ideal for high-speed trains, subways and trams. They are divided into primary suspension, between hall and bogie (elastic bushings, conical springs), and secondary, between bogie and body, where air springs improve passenger comfort. They offer low vertical natural frequency to reduce vibrations and progressive stability under varying loads. A rubber-metal buffer acts as an emergency suspension in the event of an air leak, ensuring safety.
Both suspensions (primary and secondary) are considered safety-critical organs, subject to type approval and standard checks according to specifications and user manuals. This implies that Larosi products must meet stringent standards, guaranteeing reliability in high-responsibility contexts.
Primary or secondary suspensions?
The primaries (bushings, conical springs) are located between the hall and the bogie, absorbing vibrations directly from the rails.
Secondary (air springs) are between bogie and box, improving passenger comfort.
Primary suspensions:
Air springs for primary suspensions: Used in rail vehicles (trains, metro, trams) to dampen vibrations between the wheelset (the axle with the wheels) and the bogie.
Elastic bushings: Vulcanised rubber anti-vibration elements between metal bushings, used to dampen vibrations and allow articulation of the wheelset from the bogie.
Conical springs: Similar to bushings, but with a conical pivot and a metal casing, also used for primary suspension.
Elastic joint (Silentblock): A rubber joint that connects the bushing to the bogie frame, transmitting horizontal stresses and keeping the axes parallel.
Secondary suspension:
Air springs for secondary suspension: Designed for comfort and performance, combining a rubber-frame membrane with air and a rubber-metal pad to handle horizontal, vertical and torsional movements.
Technical characteristics and advantages of Continental Springhel Saga air springs
Adjustability and customisation:
- Elastic bushings and conical springs can be varied within permissible limits to fit project specifications, suggesting flexibility in design.
- Secondary air springs provide continuous levelling via automatic height control, keeping the vehicle at a constant height (e.g. alignment with the station platform) regardless of the load.
- Vibration damping: Air springs have a low natural frequency, reducing vibration transmission, with the possibility of lowering it further for specific needs.
Emergency function:
- The rubber-metal buffer of the secondary suspension acts as a complete emergency suspension in the event of pneumatic failure or air leakage, withstanding normal stresses.
Useful fact: This increases safety and operational continuity, which is essential for public transport.
