2B9-251 Goodyear Suspension Air Bags 578-92-3-206 Rubber Air Bellows For Heavy-Duty Vehicles
Brand: GUOMAT
Model Number: 2B9251
Material: Rubber
Warranty: 1 Year
Rubber suspension air springs use highly elastic rubber and compressed air as their core components, achieving load-bearing and shock absorption through inflation and deflation, replacing traditional steel springs. They can automatically adjust vehicle height according to load changes, effectively absorbing road impacts and vibrations, reducing noise, and extending the service life of tires and suspension components. They are widely used in the suspension systems of trucks, trailers, buses, and modified vehicles.
Top Plate: 2 holes/studs; 6.4-inch diameter; 3.5-inch bolt circle diameter. Bottom Plate: 2 holes/studs; 6.4-inch diameter; 3.5-inch bolt circle diameter; aligned parallel to the top plate.
Design & Stroke
Internal Bumper: Included Operating Height Range: 3.8 in (min.) to 12.2 in (max.) Total Stroke: 8.4 in (calculated)
Product Applications
For nearly a century, air springs have been successfully applied to the suspension systems of heavy-duty trucks, tractors, and trailers, becoming a crucial component of modern air suspension systems. Air springs typically utilize compressed air supplied by the vehicle's braking system or an independent air source as their working medium. Through changes in air pressure, they achieve load-bearing, cushioning, and height adjustment functions, playing an irreplaceable role in the commercial vehicle sector.
Compared to traditional mechanical leaf springs or coil springs, air springs offer significant structural and performance advantages. Firstly, the air suspension system automatically adjusts the internal air pressure of the air springs according to changes in vehicle load and road conditions, thereby altering the suspension stiffness. This ensures good ride smoothness and comfort whether the vehicle is unloaded, partially loaded, or fully loaded, effectively reducing vibration and noise. Secondly, air springs allow for flexible adjustment of the vehicle chassis, cargo platform, or trailer height. Even without a fixed loading platform, the cargo platform can be aligned with the loading/unloading position, significantly improving loading and unloading efficiency and reducing manual labor intensity.
Furthermore, air springs can significantly reduce fatigue damage to vehicle chassis, frames, and critical components caused by vibration, extending the service life of tires, suspension, and the entire vehicle, while reducing maintenance costs. Simultaneously, a more stable vehicle posture and balanced axle load distribution contribute to improved driving safety, handling performance, and overall vehicle operating efficiency.
Therefore, air springs have become one of the key technologies for enhancing comfort, safety, and economy in modern heavy-duty vehicles and high-end transportation equipment.
