Air ride trailer suspension—also called heavy duty air suspension or trailer air suspension—represents a sophisticated advancement in modern suspension technology, specifically engineered for heavy-duty trailers and truck-trailer combinations (trailer camion). This innovative system effectively replaces conventional steel springs with precision-engineered air-filled rubber bags, commonly referred to as suspension airbags or trailer airbags, to absorb impact forces and support substantial heavy loads. Operators frequently inquire, 'What is air ride suspension?' or 'What are air suspensions?' Air ride trailer suspension systems are meticulously designed to deliver a smoother operational experience, achieve superior weight distribution, and provide enhanced cargo protection compared to traditional suspension alternatives.
Air ride suspension utilizes air springs (frequently termed air bags or airlift suspensions) in place of conventional metal springs. A dedicated air pump and compressor delivers outside air into these airbags, creating a dynamic cushioning interface between the trailer frame and axle assembly. The air pressure within the suspension airbags is continuously monitored and automatically adjusted to maintain optimal ride height and ensure trailer stability, even during load variations. This sophisticated pressure management system gives airride trailers their distinctive capability to maintain level positioning and operational stability throughout transport operations.
The air ride trailer suspension system operates through maintaining precise air pressure levels within each airbag trailer system component:
Load Sensing: Advanced electronic systems and sensors continuously monitor trailer height and detect load variations.
Air Adjustment: When the trailer deviates from level position or experiences load changes, the height control valve signals the air compressor to increase or decrease air pressure within the airbags.
Even Load Distribution: This process maintains the trailer at optimal height regardless of load conditions, ensuring all axles bear their proportional weight share, benefiting from years of axle design expertise.
Comfort and Safety: As the trailer encounters road irregularities or rough surfaces, the trailer air suspension effectively absorbs shock forces, protecting both cargo integrity and trailer structure.
