661N Contitech Air Suspension Bag W01-095-0021 Firestone Commercial Bus Air Spring
A bus air spring is an elastic shock-absorbing component installed in a bus's air suspension system, primarily consisting of a rubber air bellows, piston, end cap, and mounting plate. It utilizes compressed air as the elastic medium to support the vehicle's weight and absorb road shocks and vibrations by varying air pressure.
Compared to traditional leaf springs, bus air springs offer superior ride comfort and shock absorption while maintaining stable ride height. They are widely used in suspension systems for city buses, coaches, tourist buses, and heavy-duty commercial vehicles.
