In the commercial vehicle sector, air springs are used for safety, economy, and cargo protection. They have high market penetration in Europe and the United States, and are rapidly gaining popularity in China, driven by relevant regulations.

Application Characteristics: Almost all high-end buses and tourist buses use air suspension systems.

Core Advantages: They significantly improve passenger comfort and reduce fatigue during long journeys.

Application Characteristics: Regulations have mandated the installation of air suspension on the rear axles of heavy-duty trucks, semi-trailers, and tractors, particularly those transporting dangerous goods.

• Automatic Load Leveling: Maintains vehicle leveling regardless of load, ensuring full suspension travel and reducing uneven tire wear.
• Protects Delicate Cargo: Prevents damage to delicate instruments, electronic equipment, or fragile items caused by bumpy roads, reducing the risk of cargo damage.
• Roadworthiness: Effectively controls dynamic wheel loads, minimizing wear on the road surface.
