Technical Parameters

Triple Convoluted Type Air Spring

Triple convoluted air springs are a specific type of air spring characterized by three distinct lobes (or convolutions) in their flexible rubber bellows. This design offers a unique balance of properties, making them suitable for demanding applications where high load capacity, compactness, progressive spring rates, and stability are critical.

Primary Applications:

Heavy-Duty Truck & Trailer Suspensions:

Drive Axles: Handling the high static and dynamic loads of loaded trucks, especially on rough roads. The progressive rate helps manage varying loads and impacts.

Trailer Axles: Supporting heavy cargo loads efficiently. Compact height is often beneficial here.

Cab Suspensions: Isolating the driver's cabin from chassis vibrations and impacts, improving comfort and reducing fatigue.

Off-Highway & Construction Equipment:

Large Haul Trucks (Mining, Quarry): Essential for carrying massive payloads over extremely rough terrain. High load capacity and long stroke are critical.

Articulated Dump Trucks (ADTs): Handling heavy loads and the articulation stresses inherent in their design.

Wheel Loaders, Excavators (Suspension-equipped models): Providing ride comfort and stability for operators moving between sites or on rough job sites. Compactness can be important.

Agricultural Machinery (Large Tractors, Combines): Supporting heavy implements, improving ride quality over fields, and providing load leveling.

Industrial Machinery & Vibration Isolation:

Large Presses, Machine Tools: Leveling heavy machinery and isolating vibrations to protect the machine foundation and surrounding equipment.

Test Rigs & Simulators: Providing precise load support and vibration isolation for sensitive testing environments.

Foundations for Sensitive Equipment: Isolating equipment like MRI machines or precision manufacturing tools from building vibrations.

Bus Suspensions:

Heavy-Duty Coaches & City Buses: Supporting the vehicle structure, passengers, and cargo. The progressive rate provides a good balance of comfort when empty and stability when fully loaded. Compact height can be advantageous.
