DESCRIPTION

Rolling lobe air springs are used in extremely confined spaces in tram bogies and low-floor bogies.

As an elastic link between the bogie and railcar body, air bellows distance the railcar body to the platform and absorb track irregularities by minimising the transmission.

Benefits

• Compact design
• Heigh load capacity (load / diameter)
• Reduced number of parts (no bead ring)

Specifications

• Diameter: ~ø450-750mm
• Vertical loads: up to 140kN
• Lateral deflection: up to ±100mm (in air spring system)
• Operating pressure range: 2-7 bar
• Operating temperature: -45°C (-50°C) up to +65°C (+70°C)
• Ride quality at the front of the trailer: The ride quality of the freight in the front of the trailer was examined and tests showed that the front ride quality was a function of the tractor suspension, not the trailer suspension, proving that the trailer suspension had little effect on the ride quality of the freight.

• Ride quality at the rear of the trailer: The graph (right) shows the industry standard spring suspension compared with the average results of the four most popular air suspensions, proving that the average ride quality of the top four air suspensions is very close to the industry standard spring suspension. In fact, under most circumstances, the spring-ride suspension provided a better ride quality.Spring Ride Protects Freight and your Bottom Line
