This suspension component, commonly found on heavy-duty trucks from a well-known manufacturer, combines an air ride system with leaf springs. This design allows for a balance between load-carrying capacity, ride comfort, and stability. For example, a Peterbilt truck hauling heavy freight across varied terrain might utilize this suspension type for optimized performance.
The incorporation of both air springs and leaf springs offers several advantages. The leaf springs provide the structural strength necessary to support substantial loads, while the air springs allow for adjustable ride height and improved isolation from road vibrations. Historically, this combination has been favored in applications where consistent load support and driver comfort are paramount, leading to reduced driver fatigue and potential vehicle maintenance costs over time.
