2B14-354 Truck Single Convoluted Air Spring W01-358-7145 Firestone Air Suspension Air Bags

The application of air springs in truck suspensions primarily replaces traditional leaf springs, achieving three main functions: shock absorption, load bearing, and vehicle height adjustment. By adjusting the internal air pressure of the air spring, the suspension stiffness can automatically adjust with changes in load, resulting in greater comfort when unloaded and greater stability when heavily loaded, effectively reducing bumps and impacts. Simultaneously, air springs maintain a constant vehicle height, preventing the vehicle from tilting forward and backward due to changes in load, thus improving driving safety and handling. Compared to traditional steel suspensions, air suspensions significantly reduce damage from cargo vibrations and extend the lifespan of the entire vehicle and tires.

Trailer Suspension Applications

The GUOMAT 2B7145 is a double-fold air spring developed by GUOMAT specifically for trailer air suspension systems. It is widely used in the rear axle suspension of semi-trailers, flatbed trailers, refrigerated trailers, and heavy-duty transport trailers.

Key Application Advantages

Stable Load Bearing: Double-fold structure design provides strong support, suitable for medium to heavy-duty trailer conditions.
Shock Absorption and Cushioning: Effectively filters road impacts, reducing fatigue damage to the axle and frame.
Height Adjustable: Automatically levels the trailer with a height valve, ensuring consistency between full and empty loads.
Cargo Protection: Reduces bumps and vibrations, particularly suitable for cold chain, precision equipment, and high-value cargo transportation.
Durable and Reliable: High-strength rubber and metal end cap structure, adaptable to long-term, high-frequency use environments.

Applicable Working Conditions

Long-haul logistics transportation
Port container transportation
Refrigerated and cold chain trailers
Heavy-duty engineering transport trailers

The GUOMAT 2B7145 can directly replace many international brand models of the same type. It supports customized matching of installation dimensions, interface direction, and working stroke. Easy installation and low maintenance costs make it an ideal core component of trailer air suspension systems.
