Suspension System Air Spring Bag 1R1A 380 260 Firestone Rubber Air
Bellow W01-095-0204
Product Description
Bus air spring bags (commonly called air springs or air bellows)
are durable, flexible rubber containers mounted at each wheel or
axle of a bus. Instead of metal coils or leaf springs, they use
compressed air to support the vehicle's weight, absorb road shocks,
and provide a smooth, level ride.

How They Work
The system is more than just the bags; it's a complete,
interconnected setup:
Air Supply: An engine-driven air compressor fills storage tanks with
compressed air.
Height Control Valves: Mechanical or electronic sensors are linked to the axles. They
monitor the height of the bus.
Automatic Adjustment:
- When passengers board and the bus gets heavier, the chassis starts
to sink.
- The height sensor detects this drop and opens a valve, allowing
compressed air to fill the air spring bags, raising the bus back to
its pre-set "ride height."
- When passengers exit and the bus gets lighter, the chassis rises.
The sensor releases air from the bags to lower the bus back to the
correct height.
- This process ensures the bus always stays level, which is critical
for safety, handling, and passenger comfort.
Common Issues and Maintenance
Leaks: The most common issue. Air can leak from a cracked or perished
rubber bag, a faulty seal, or a damaged air line. You'll often hear
a hissing sound.
Failed Compressor or Dryer: If the compressor fails, the entire system loses pressure, and the
bus will sag. A failed dryer can lead to water in the system,
causing corrosion and valve failures.
Faulty Height Valve: A stuck valve can cause the bus to over-inflate (ride too high) or
deflate completely (ride on the emergency stops).
