Product Information

Trailer Suspension Air Spring

1. The core function of air spring
Load support: adapt to different loads by adjusting the internal air pressure to avoid the rigid impact of traditional leaf springs.
Shock absorption and buffering: absorb road vibrations to protect cargo and vehicle structure.
Height adjustment: keep the vehicle level (especially when unevenly loaded), improve passability and safety.
Extended life: reduce wear of mechanical parts and reduce maintenance costs.

2. Main types
Bag air spring: composed of rubber airbags and metal cover plates, suitable for small and medium-sized trailers, lightweight and low cost.
Sleeve (piston) air spring: with piston structure, stronger support force, common in heavy trailers or high-load scenarios.
Membranous air spring: compact design, mostly used in suspension systems with limited space.

3. Key advantages
Adaptive load: air pressure automatically adjusts with load to avoid over-hard/soft suspension when overloaded or unloaded.
Improved comfort: compared with leaf springs, it reduces the transmission of road vibration by about 30%-50%.
Protect cargo: Reduce damage to delicate or fragile cargo caused by bumps.
Adjustability: Some systems support manual or electronic control to adjust the height and hardness of the suspension in real time.

4. Typical application scenarios
Freight trailers: such as container transport and logistics trailers.
RV/caravan trailers: Improve the stability when parking.
Special equipment trailers: such as transporting heavy machinery and precision instruments.
Modification and upgrade: Replace old leaf springs to improve trailer performance.
